1857 - Dred Scott decision in the U.S. Supreme Court (originated in the Missouri Territory) - declared the American Citizenship rights did not extend to blacks whether they were slaves or free.

# data[].attributes.attachment_link.readable_text
Dred Scott v. Sandford, 60 U.S. (19 How.) 393 (1857), was a landmark decision of the United States Supreme Court that held the U.S. Constitution did not extend American citizenship to people of black African descent, and thus they could not enjoy the rights and privileges the Constitution conferred upon American citizens. The decision is widely considered the worst ever rendered in the Supreme Court's history, being widely denounced for its overt racism, perceived judicial activism and poor legal reasoning, and for its crucial role in the start of the American Civil War four years later. Legal scholar Bernard Schwartz said that it "stands first in any list of the worst Supreme Court decisions". Chief Justice Charles Evans Hughes called it the Court's "greatest self-inflicted wound".

The decision involved the case of Dred Scott, an enslaved black man whose owners had taken him from Missouri, a slave-holding state, into Illinois and the Wisconsin Territory, where slavery was illegal. When his owners later brought him back to Missouri, Scott sued for his freedom and claimed that because he had been taken into " free" U.S. territory, he had automatically been freed and was legally no longer a slave. Scott sued first in Missouri state court, which ruled that he was still a slave under its law. He then sued in U.S. federal court, which ruled against him by deciding that it had to apply Missouri law to the case. He then appealed to the U.S. Supreme Court.

In March 1857, the Supreme Court issued a 7-2 decision against Scott. In an opinion written by Chief Justice Roger Taney, the Court ruled that people of African descent "are not included, and were not intended to be included, under the word 'citizens' in the Constitution, and can therefore claim none of the rights and privileges which that instrument provides for and secures to citizens of the United States". Taney supported his ruling with an extended survey of American state and local laws from the time of the Constitution's drafting in 1787 that purported to show that a "perpetual and impassable barrier was intended to be erected between the white race and the one which they had reduced to slavery". Because the Court ruled that Scott was not an American citizen, he was also not a citizen of any state and, accordingly, could never establish the " diversity of citizenship" that Article III of the U.S. Constitution requires for a U.S. federal court to be able to exercise jurisdiction over a case. After ruling on those issues surrounding Scott, Taney struck down the Missouri Compromise as a limitation on slave owners' property rights that exceeded the U.S. Congress's constitutional powers.

Although Taney and several other justices hoped the decision would settle the slavery controversy, which was increasingly dividing the American public, the decision only exacerbated interstate tension. Taney's majority opinion suited the slaveholding states, but was intensely decried in all the other states. The decision inflamed the national debate over slavery and deepened the divide that led ultimately to the American Civil War. In 1865, after the Union's victory, the Court's ruling in Dred Scott was superseded by the passage of the Thirteenth Amendment to the U.S. Constitution, which abolished slavery, and the Fourteenth Amendment, whose first section guaranteed citizenship for "[a]ll persons born or naturalized in the United States and subject to the jurisdiction thereof".

Historians agree that the Court decision was a major disaster for the nation as it dramatically inflamed tensions leading to the Civil War. In 2022 historian David W. Blight argues that 1857 was, "the great pivot on the road to disunion...largely because of the Dred Scott case, which stoked the fear, distrust and conspiratorial hatred already common in both the North and the South to new levels of intensity." The ruling is widely considered a blatant act of judicial activism with the intent of bringing finality to the territorial crisis resulting from the Louisiana Purchase by creating a constitutional right to own slaves anywhere in the country while permanently disenfranchising all people of African descent. The court's decision to overturn the Missouri Compromise, which had already been replaced with the Kansas-Nebraska Act and thus was a legally moot issue, is cited as proof of this because the latter act was determined by the due process of popular sovereignty, and thus could not be overturned the same way the court did the Missouri compromise. During the United States election of 1860, abolitionists formed the Republican Party that rejected the ruling as being corrupted by partisanship and non-binding because the court had no jurisdiction. Their Presidential nominee, Abraham Lincoln, stated he would not permit slavery anywhere in the country except where it already existed, which directly contradicted the court's ruling. His election is considered the final event that led the Southern states to secede from the Union, igniting the American Civil War.

In the late 1810s, a major political dispute arose over the creation of new American states from the vast territory the United States had acquired from France in 1803 through the Louisiana Purchase. The dispute centered on whether the new states would be "free" states, like the Northern states, in which slavery would be illegal, or whether they would be "slave" states, like the Southern states, in which slavery would be legal. The Southern states wanted the new states to be slave states in order to enhance their own political and economic power. The Northern states wanted the new states to be free states for their own political and economic reasons, as well as their moral concerns over allowing the institution of slavery to expand.

In 1820, the U.S. Congress passed legislation known as the " Missouri Compromise" that was intended to resolve the dispute. The Compromise first admitted Maine into the Union as a free state, then created Missouri out of a portion of the Louisiana Purchase territory and admitted it as a slave state; at the same time it prohibited slavery in the area north of the Parallel 36°30′ north, where most of the territory lay. The legal effects of a slaveowner taking his slaves from Missouri into the free territory north of the 36°30′ north parallel, as well as the constitutionality of the Missouri Compromise itself, eventually came to a head in the Dred Scott case.

Dred Scott was born a slave in Virginia around 1799. Little is known of his early years. His owner, Peter Blow, moved to Alabama in 1818, taking his six slaves along to work a farm near Huntsville. In 1830, Blow gave up farming and settled in St. Louis, Missouri, where he sold Scott to U.S. Army surgeon Dr. John Emerson. After purchasing Scott, Emerson took him to Fort Armstrong in Illinois. A free state, Illinois had been free as a territory under the Northwest Ordinance of 1787, and had prohibited slavery in its constitution in 1819 when it was admitted as a state.

In 1836, Emerson moved with Scott from Illinois to Fort Snelling in the Wisconsin territory in what has become the state of Minnesota. Slavery in the Wisconsin Territory (some of which, including Fort Snelling, was part of the Louisiana Purchase) was prohibited by the U.S. Congress under the Missouri Compromise. During his stay at Fort Snelling, Scott married Harriet Robinson in a civil ceremony by Harriet's owner, Major Lawrence Taliaferro, a justice of the peace who was also an Indian agent. The ceremony would have been unnecessary had Dred Scott been a slave, as slave marriages had no recognition in the law.

In 1837, the army ordered Emerson to Jefferson Barracks Military Post, south of St. Louis. Emerson left Scott and his wife at Fort Snelling, where he leased their services out for profit. By hiring Scott out in a free state, Emerson was effectively bringing the institution of slavery into a free state, which was a direct violation of the Missouri Compromise, the Northwest Ordinance, and the Wisconsin Enabling Act.

Before the end of the year, the army reassigned Emerson to Fort Jesup in Louisiana, where Emerson married Eliza Irene Sanford in February 1838. Emerson sent for Scott and Harriet, who proceeded to Louisiana to serve their master and his wife. Within months, Emerson was transferred back to Fort Snelling. While en route to Fort Snelling, Scott's daughter Eliza was born on a steamboat under way on the Mississippi River between Illinois and what would become Iowa. Because Eliza was born in free territory, she was technically born as a free person under both federal and state laws. Upon entering Louisiana, the Scotts could have sued for their freedom, but did not. One scholar suggests that, in all likelihood, the Scotts would have been granted their freedom by a Louisiana court, as it had respected laws of free states that slaveholders forfeited their right to slaves if they brought them in for extended periods. This had been the holding in Louisiana state courts for more than 20 years.

Toward the end of 1838, the army reassigned Emerson back to Fort Snelling. By 1840, Emerson's wife Irene returned to St. Louis with their slaves, while Dr. Emerson served in the Seminole War. While in St. Louis, she hired them out. In 1842, Emerson left the army. After he died in the Iowa Territory in 1843, his widow Irene inherited his estate, including the Scotts. For three years after John Emerson's death, she continued to lease out the Scotts as hired slaves. In 1846, Scott attempted to purchase his and his family's freedom, but Irene Emerson refused, prompting Scott to resort to legal recourse.

Having been unsuccessful in his attempt to purchase his freedom, Dred Scott, with the help of his legal advisers, sued Emerson for his freedom in the Circuit Court of St. Louis County on April 6, 1846. A separate petition was filed for his wife Harriet, making them the first married couple to file freedom suits in tandem in its 50-year history. They received financial assistance from the family of Dred's previous owner, Peter Blow. Blow's daughter Charlotte was married to Joseph Charless, an officer at the Bank of Missouri. Charless signed legal documents as security for the Scotts and later secured the services of the bank's attorney, Samuel Mansfield Bay, for the trial.

It was expected that the Scotts would win their freedom with relative ease. By 1846, dozens of freedom suits had been won in Missouri by former slaves. Most had claimed their legal right to freedom on the basis that they, or their mothers, had previously lived in free states or territories. Among the most important legal precedents were Winny v. Whitesides and Rachel v. Walker. In Winny v. Whitesides, the Missouri Supreme Court had ruled in 1824 that a person who had been held as a slave in Illinois, where slavery was illegal, and then brought to Missouri, was free by virtue of residence in a free state. In Rachel v. Walker, the state supreme court had ruled that a U.S. Army officer who took a slave to a military post in a territory where slavery was prohibited and retained her there for several years, had thereby "forfeit[ed] his property". Rachel, like Dred Scott, had accompanied her enslaver to Fort Snelling.

Scott was represented by three different lawyers from the filing of the original petition to the time of the actual trial, over one year later. The first was Francis B. Murdoch, a prolific freedom suit attorney who abruptly left St. Louis. Murdoch was replaced by Charles D. Drake, an in-law of the Blow family. When Drake also left the state, Samuel M. Bay took over as the Scotts' lawyer. Irene Emerson was represented by George W. Goode, a proslavery lawyer from Virginia. By the time the case went to trial, it had been reassigned from Judge John M. Krum, who was proslavery, to Judge Alexander Hamilton, who was known to be sympathetic to freedom suits.

Dred Scott v. Irene Emerson finally went to trial for the first time on June 30, 1847. Henry Peter Blow testified in court that his father had owned Dred and sold him to John Emerson. The fact that Scott had been taken to live on free soil was clearly established through depositions from witnesses who had known Scott and Dr. Emerson at Fort Armstrong and Fort Snelling. Grocer Samuel Russell testified that he had hired the Scotts from Irene Emerson and paid her father, Alexander Sanford, for their services. Upon cross examination, however, Russell admitted that the leasing arrangements had actually been made by his wife, Adeline.

Thus, Russell's testimony was ruled hearsay, and the jury returned a verdict for Emerson. This created a seemingly contradictory outcome in which Scott was ordered by the court to remain Irene Emerson's slave, because he had been unable to prove that he was previously Irene Emerson's slave.

Bay moved immediately for a new trial on the basis that Scott's case had been lost due to a technicality which could be rectified, rather than the facts. Judge Hamilton finally issued the order for a new trial on December 2, 1847. Two days later, Emerson's lawyer objected to a new trial by filing a bill of exceptions. The case was then taken on writ of error to the Supreme Court of Missouri. Scott's new lawyers, Alexander P. Field and David N. Hall, argued that the writ of error was inappropriate because the lower court had not yet issued a final judgment. The state supreme court agreed unanimously with their position and dismissed Emerson's appeal on June 30, 1848. The main issue before the court at this stage was procedural and no substantive issues were discussed.

Before the state supreme court had convened, Goode had presented a motion on behalf of Emerson to have Scott taken into custody and hired out. On March 17, 1848, Judge Hamilton issued the order to the St. Louis County sheriff. Anyone hiring Scott had to post a bond of six-hundred dollars. Wages he earned during that time were placed in escrow, to be paid to the party that prevailed in the lawsuit. Scott would remain in the sheriff's custody or hired out by him until March 18, 1857. One of Scott's lawyers, David N. Hall, hired him starting March 17, 1849.

The St. Louis Fire of 1849, a cholera epidemic, and two continuances delayed the retrial in the St. Louis Circuit Court until January 12, 1850. Irene Emerson was now defended by Hugh A. Garland and Lyman D. Norris, while Scott was represented by Field and Hall. Judge Alexander Hamilton was presiding. The proceedings were similar to the first trial. The same depositions from Catherine A. Anderson and Miles H. Clark were used to establish that Dr. Emerson had taken Scott to free territory.

This time, the hearsay problem was surmounted by a deposition from Adeline Russell stating that she had hired the Scotts from Irene Emerson, thereby proving that Emerson claimed them as her slaves. Samuel Russell testified in court once again that he had paid for their services. The defense then changed strategy and argued in their summation that Mrs. Emerson had every right to hire out Dred Scott, because he had lived with Dr. Emerson at Fort Armstrong and Fort Snelling under military jurisdiction, not under civil law. In doing so, the defense ignored the precedent set by Rachel v. Walker. In his rebuttal, Hall stated that the fact that they were military posts did not matter, and pointed out that Dr. Emerson had left Scott behind at Fort Snelling, hired out to others, after being reassigned to a new post.

The jury quickly returned a verdict in favor of Dred Scott, nominally making him a free man. Judge Hamilton declared Harriet, Eliza and Lizzie Scott to be free as well. Garland moved immediately for a new trial, and was overruled. On February 13, 1850, Emerson's defense filed a bill of exceptions, which was certified by Judge Hamilton, setting into motion another appeal to the Missouri Supreme Court. Counsel for the opposing sides signed an agreement that moving forward, only Dred Scott v. Irene Emerson would be advanced, and that any decision made by the high court would apply to Harriet's suit, also. In 1849 or 1850, Irene Emerson left St. Louis and moved to Springfield, Massachusetts. Her brother, John F. A. Sanford, continued looking after her business interests when she left, and her departure had no impact on the case.

Both parties filed briefs with the Supreme Court of Missouri on March 8, 1850. A busy docket delayed consideration of the case until the October term. By then, the issue of slavery had become politically charged, even within the judiciary. Although the Missouri Supreme Court had not yet overturned precedent in freedom suits, in the 1840s, the court's proslavery justices had explicitly stated their opposition to freeing slaves. After the court convened on October 25, 1850, the two justices who were proslavery anti-Benton Democrats - William Barclay Napton and James Harvey Birch - persuaded John Ferguson Ryland, a Benton Democrat, to join them in a unanimous decision that Dred Scott remained a slave under Missouri law. However, Judge Napton delayed writing the court's opinion for months. Then in August 1851, both Napton and Birch lost their seats in the Missouri Supreme Court, following the state's first supreme court election, with only Ryland remaining as an incumbent. The case thus needed to be considered again by the newly elected court. The reorganized Missouri Supreme Court now included two "moderates" - Hamilton Gamble and John Ryland - and one staunch proslavery justice, William Scott.

David N. Hall had prepared the brief for Dred Scott, but died in March 1851. Alexander P. Field continued alone as counsel for Dred Scott, and resubmitted the same briefs from 1850 for both sides. On November 29, 1851, the case was taken under consideration, on written briefs alone, and a decision was reached. However, before Judge Scott could write the court's opinion, Lyman Norris, co-counsel for Irene Emerson, obtained permission to submit a new brief he had been preparing, to replace the original one submitted by Garland.

Norris's brief has been characterized as "a sweeping denunciation of the authority of both the [Northwest] Ordinance of 1787 and the Missouri Compromise." Although he stopped short of questioning their constitutionality, Norris questioned their applicability and criticized the early Missouri Supreme Court, ridiculing former Justice George Tompkins as "the great apostle of freedom at that day." Reviewing the court's past decisions on freedom suits, Norris acknowledged that if Rachel v. Walker was allowed to stand, his client would lose. Norris then challenged the concept of "once free, always free", and asserted that the court under Tompkins had been wrong to rule that the Ordinance of 1787 remained in force after the ratification of the U.S. Constitution in 1788. Finally, he argued that the Missouri Compromise should be disregarded whenever it interfered with Missouri law, and that the laws of other states should not be enforced, if their enforcement would cause Missouri citizens to lose their property. In support of his argument, he cited Chief Justice Roger B. Taney's opinion in the United States Supreme Court case Strader v. Graham, which argued that the status of a slave returning from a free state must be determined by the slave state itself. According to historian Walter Ehrlich, the closing of Norris's brief was "a racist harangue that not only revealed the prejudices of its author, but also indicated how the Dred Scott case had become a vehicle for the expression of such views". Noting that Norris's proslavery "doctrines" were later incorporated into the court's final decision, Ehrlich writes (emphasis his):

From this point on, the Dred Scott case clearly changed from a genuine freedom suit to the controversial political issue for which it became infamous in American history.

On March 22, 1852, Judge William Scott announced the decision of the Missouri Supreme Court that Dred Scott remained a slave, and ordered the trial court's judgment to be reversed. Judge Ryland concurred, while Chief Justice Hamilton Gamble dissented. The majority opinion written by Judge Scott focused on the issue of comity or conflict of laws, and relied on " states' rights" rhetoric:

Every State has the right of determining how far, in a spirit of comity, it will respect the laws of other States. Those laws have no intrinsic right to be enforced beyond the limits of the State for which they were enacted. The respect allowed them will depend altogether on their conformity to the policy of our institutions. No State is bound to carry into effect enactments conceived in a spirit hostile to that which pervades her own laws.

Judge Scott did not deny the constitutionality of the Missouri Compromise, and acknowledged that its prohibition of slavery was "absolute", but only within the specified territory. Thus, a slave crossing the border could obtain his freedom, but only within the court of the free state. Rejecting the court's own precedent, Scott argued that "'Once free' did not necessarily mean 'always free.'" He cited the Kentucky Court of Appeals decision in Graham v. Strader, which had held that a Kentucky slaveowner who permitted a slave to go to Ohio temporarily, did not forfeit ownership of the slave. To justify overturning three decades of precedent, Judge Scott argued that circumstances had changed:

Times now are not as they were when the former decisions on this subject were made. Since then not only individuals but States have been possessed with a dark and fell spirit in relation to slavery, whose gratification is sought in the pursuit of measures, whose inevitable consequence must be the overthrow and destruction of our government. Under such circumstances it does not behoove the State of Missouri to show the least countenance to any measure which might gratify this spirit. She is willing to assume her full responsibility for the existence of slavery within her limits, nor does she seek to share or divide it with others.

On March 23, 1852, the day after the Missouri Supreme Court decision had been announced, Irene Emerson's lawyers filed an order in the St. Louis Circuit Court for the bonds signed by the Blow family to cover the Scotts' court costs; return of the slaves themselves; and transfer of their wages earned over four years, plus 6 percent interest. On June 29, 1852, Judge Hamilton overruled the order.

The case looked hopeless, and the Blow family could no longer pay for Scott's legal costs. Scott also lost both of his lawyers when Alexander Field moved to Louisiana and David Hall died. The case was undertaken by Roswell Field, who employed Scott as a janitor. Field also discussed the case with LaBeaume, who had taken over the lease on the Scotts in 1851. After the Missouri Supreme Court decision, Judge Hamilton turned down a request by Emerson's lawyers to release the rent payments from escrow and to deliver the slaves into their owner's custody.

In 1853, Dred Scott again sued his current owner John Sanford, but this time in federal court. Sanford returned to New York and the federal courts had diversity jurisdiction under Article III, Section 2 of the U.S. Constitution. In addition to the existing complaints, Scott alleged that Sanford had assaulted his family and held them captive for six hours on January 1, 1853.

At trial in 1854, Judge Robert William Wells directed the jury to rely on Missouri law on the question of Scott's freedom. Since the Missouri Supreme Court had held that Scott remained a slave, the jury found in favor of Sanford. Scott then appealed to the U.S. Supreme Court, where the clerk misspelled the defendant's name, and the case was recorded as Dred Scott v. Sandford, with an ever-erroneous title. Scott was represented before the Supreme Court by Montgomery Blair and George Ticknor Curtis, whose brother Benjamin was a Supreme Court Justice. Sanford was represented by Reverdy Johnson and Henry S. Geyer.

When the case was filed, the two sides agreed on a statement of facts that claimed Scott had been sold by Dr. Emerson to John Sanford, though this was a legal fiction. Dr. Emerson had died in 1843, and Dred Scott had filed his 1847 suit against Irene Emerson. There is no record of Dred Scott's transfer to Sanford or of his transfer back to Irene. John Sanford died shortly before Scott's manumission, and Scott was not listed in the probate records of Sanford's estate. Also, Sanford was not acting as Dr. Emerson's executor, as he was never appointed by a probate court, and the Emerson estate had been settled when the federal case was filed.

The murky circumstances of ownership led many to conclude the parties to Dred Scott v. Sandford contrived to create a test case. Mrs. Emerson's remarriage to abolitionist U.S. Representative Calvin C. Chaffee seemed suspicious to contemporaries, and Sanford was thought to be a front and to have allowed himself to be sued, despite not actually being Scott's owner. Nevertheless, Sanford had been involved in the case since 1847, before his sister married Chaffee. He had secured counsel for his sister in the state case, and he engaged the same lawyer for his own defense in the federal case. Sanford also consented to be represented by genuine pro-slavery advocates before the Supreme Court, rather than to put up a token defense.

Historians discovered that after the Supreme Court heard arguments in the case but before it issued a ruling, President-elect James Buchanan wrote to his friend, Supreme Court Associate Justice John Catron, to ask whether the case would be decided by the Court before his inauguration in March 1857. Buchanan hoped that the decision would quell unrest in the country over the slavery issue by issuing a ruling to take it out of political debate. He later successfully pressured Associate Justice Robert Cooper Grier, a Northerner, to join the Southern majority in Dred Scott to prevent the appearance that the decision was made along sectional lines. According to historian Paul Finkelman:

Buchanan already knew what the Court was going to decide. In a major breach of Court etiquette, Justice Grier, who, like Buchanan, was from Pennsylvania, had kept the President-elect fully informed about the progress of the case and the internal debates within the Court. When Buchanan urged the nation to support the decision, he already knew what Taney would say. Republican suspicions of impropriety turned out to be fully justified.

Biographer Jean H. Baker argues that Buchanan's use of political pressure on a member of a sitting court was regarded then, as now, to be highly improper. Republicans fueled speculation as to Buchanan's influence by publicizing that Taney had secretly informed Buchanan of the decision. Buchanan declared in his inaugural address that the slavery question would "be speedily and finally settled" by the Supreme Court.

On March 6, 1857, the U.S. Supreme Court ruled against Dred Scott in a 7-2 decision that fills over 200 pages in the United States Reports. The decision contains opinions from all nine justices, but the "majority opinion" has always been the focus of the controversy.

Seven justices formed the majority and joined an opinion written by Chief Justice Roger Taney. Taney began the Court's opinion with what he saw as the core issue in the case: whether or not black people could possess federal citizenship under the U.S. Constitution.

The question is simply this: Can a negro, whose ancestors were imported into this country, and sold as slaves, become a member of the political community formed and brought into existence by the Constitution of the United States, and as such become entitled to all of the rights, and privileges, and immunities, guarantied [sic] by that instrument to the citizen?

In answer, the Court ruled that they could not. It held that black people could not be American citizens, and therefore a lawsuit to which they were a party could never qualify for the " diversity of citizenship" that Article III of the Constitution requires for American federal courts to have jurisdiction over cases that do not involve federal questions.

The primary rationale for the Court's ruling was Taney's assertion that black African slaves and their descendants were never intended to be part of the American social and political landscape.

We think ... that they [black people] are not included, and were not intended to be included, under the word "citizens" in the Constitution, and can therefore claim none of the rights and privileges which that instrument provides for and secures to citizens of the United States. On the contrary, they were at that time [of America's founding] considered as a subordinate and inferior class of beings who had been subjugated by the dominant race, and, whether emancipated or not, yet remained subject to their authority, and had no rights or privileges but such as those who held the power and the Government might choose to grant them.

Taney then extensively reviewed laws from the original American states that involved the status of black Americans at the time of the Constitution's drafting in 1787. He concluded that these laws showed that a "perpetual and impassable barrier was intended to be erected between the white race and the one which they had reduced to slavery". Thus, he concluded, black people were not American citizens, and could not sue as citizens in federal courts. This meant that U.S. states lacked the power to alter the legal status of black people by granting them state citizenship.

It is difficult at this day to realize the state of public opinion in relation to that unfortunate race, which prevailed in the civilized and enlightened portions of the world at the time of the Declaration of Independence, and when the Constitution of the United States was framed and adopted. ... They had for more than a century before been regarded as beings of an inferior order ... and so far inferior, that they had no rights which the white man was bound to respect; and that the negro might justly and lawfully be reduced to slavery for his benefit.

This holding normally would have ended the decision, since it disposed of Dred Scott's case, but Taney did not conclude the matter before the Court in the normal manner. He went on to assess the constitutionality of the Missouri Compromise itself, writing that the Compromise's legal provisions intended to free slaves who were living north of the 36°N latitude line in the western territories. In the Court's judgment, this would constitute the government depriving slaveowners of their property-since slaves were legally the property of their owners-without due process of law, which is forbidden under the Fifth Amendment to the Constitution. Taney also reasoned that the Constitution and the Bill of Rights implicitly precluded any possibility of constitutional rights for black African slaves and their descendants. Thus, Taney concluded:

Now, ... the right of property in a slave is distinctly and expressly affirmed in the Constitution. ... Upon these considerations, it is the opinion of the court that the act of Congress which prohibited a citizen from holding and owning property of this kind in the territory of the United States north of the [36°N 36' latitude] line therein mentioned is not warranted by the Constitution, and is therefore void....

Taney held that the Missouri Compromise was unconstitutional, marking the first time since the 1803 case Marbury v. Madison that the Supreme Court had struck down a federal law, although the Missouri Compromise had already been effectively overridden by the Kansas-Nebraska Act. Taney made this argument on a narrow definition of the Property Clause of Section 3 of Article 4 of the Constitution. The Property Clause states, "The Congress shall have Power to dispose of and make all needful Rules and Regulations respecting the Territory or other Property belonging to the United States..." Taney made the argument that the Property Clause "applied only to the property which the States held in common at that time, and has no reference whatever to any territory or other property which the new sovereignty might afterwards itself acquire." Taney asserted that because the Northwest Territory was not part of the United States at the time of the Constitution's ratification, Congress did not have the authority to ban slavery in the territory. According to Taney, the Missouri Compromise exceeded the scope of Congress's powers and was unconstitutional, and thus Dred Scott was still a slave regardless of his time spent in the parts of the Northwest Territory that were north of 36°N, and he was still a slave under Missouri law, and the Court had to follow Missouri law in the matter. For all these reasons, the Court concluded that Scott could not bring suit in U.S. federal court.

Justices Benjamin Robbins Curtis and John McLean were the only two dissenters from the Court's decision, and both filed dissenting opinions.

Curtis's 67-page dissent argued that the Court's conclusion that black people could not possess federal U.S. citizenship was legally and historically baseless. Curtis pointed out that at the time of the Constitution's adoption in 1789, black men could vote in five of the 13 states. Legally, that made them citizens of both their individual states and the United States federally. Curtis cited many state statutes and state court decisions supporting his position. His dissent was "extremely persuasive", and it prompted Taney to add 18 additional pages to his opinion in an attempt to rebut Curtis's arguments.

McLean's dissent deemed the argument that black people could not be citizens "more a matter of taste than of law". He attacked much of the Court's decision as obiter dicta that was not legally authoritative on the ground that once the court determined that it did not have jurisdiction to hear Scott's case, it should have simply dismissed the action, rather than passing judgment on the merits of the claims.

Curtis and McLean both attacked the Court's overturning of the Missouri Compromise on its merits. They noted that it was not necessary to decide the question and that none of the authors of the Constitution had ever objected on constitutional grounds to the Congress's adoption of the antislavery provisions of the Northwest Ordinance passed by the Continental Congress or the subsequent acts that barred slavery north of 36°30' N, or the prohibition on importing slaves from overseas passed in 1808. Curtis said slavery was not listed in the constitution as a "natural right", but rather a creation of municipal law. He pointed out the constitution said "The Congress shall have Power to dispose of and make all needful Rules and Regulations respecting the Territory or other Property belonging to the United States; and nothing in this Constitution shall be so construed as to Prejudice any Claims of the United States, or of any particular State." Since slavery was not mentioned as an exception, he felt a prohibition of it fell within the scope of needed rules and regulations Congress was free to pass.

The Supreme Court's decision in Dred Scott was "greeted with unmitigated wrath from every segment of the United States except the slave holding states." The American political historian Robert G. McCloskey described:

The tempest of malediction that burst over the judges seems to have stunned them; far from extinguishing the slavery controversy, they had fanned its flames and had, moreover, deeply endangered the security of the judicial arm of government. No such vilification as this had been heard even in the wrathful days following the Alien and Sedition Acts. Taney's opinion was assailed by the Northern press as a wicked "stump speech" and was shamefully misquoted and distorted. "If the people obey this decision," said one newspaper, "they disobey God."

Many Republicans, including Abraham Lincoln, who was rapidly becoming the leading Republican in Illinois, regarded the decision as part of a plot to expand and eventually impose the legalization of slavery throughout all of the states. Some southern extremists wanted all states to recognize slavery as a constitutional right. Lincoln rejected the court's majority opinion that "the right of property in a slave is distinctly and expressly affirmed in the Constitution," pointing out that the constitution did not ever mention property in reference to slaves and in fact explicitly referred to them as "persons". Southern Democrats considered Republicans to be lawless rebels who were provoking disunion by their refusal to accept the Supreme Court's decision as the law of the land. Many northern opponents of slavery offered a legal argument for refusing to recognize the Dred Scott decision on the Missouri Compromise as binding. They argued that the Court's determination that the federal courts had no jurisdiction to hear the case rendered the remainder of the decision obiter dictum-a non binding passing remark rather than an authoritative interpretation of the law. Douglas attacked that position in the Lincoln-Douglas debates:

Mr. Lincoln goes for a warfare upon the Supreme Court of the United States, because of their judicial decision in the Dred Scott case. I yield obedience to the decisions in that court-to the final determination of the highest judicial tribunal known to our constitution.

In a speech at Springfield, Illinois, Lincoln responded that the Republican Party was not seeking to defy the Supreme Court, but he hoped they could convince it to reverse its ruling.

We believe, as much as Judge Douglas, (perhaps more) in obedience to, and respect for the judicial department of government. We think its decisions on Constitutional questions, when fully settled, should control, not only the particular cases decided, but the general policy of the country, subject to be disturbed only by amendment of the Constitution as provided in that instrument itself. More than this would be revolution. But we think the Dred Scott decision is erroneous. We know the court that made it, has often over-ruled its own decisions, and we shall do what we can to have it to over-rule this. We offer no resistance to it.

Democrats had refused to accept the court's interpretation of the U.S. Constitution as permanently binding. During the Andrew Jackson administration, Taney, then Attorney General, had written:

Whatever may be the force of the decision of the Supreme Court in binding the parties and settling their rights in the particular case before them, I am not prepared to admit that a construction given to the constitution by the Supreme Court in deciding any one or more cases fixes of itself irrevokably [ sic] and permanently its construction in that particular and binds the states and the Legislative and executive branches of the General government, forever afterwards to conform to it and adopt it in every other case as the true reading of the instrument although all of them may unite in believing it erroneous.

Frederick Douglass, a prominent black abolitionist who considered the decision to be unconstitutional and Taney's reasoning contrary to the Founding Fathers' vision, predicted that political conflict could not be avoided:

The highest authority has spoken. The voice of the Supreme Court has gone out over the troubled waves of the National Conscience.... [But] my hopes were never brighter than now. I have no fear that the National Conscience will be put to sleep by such an open, glaring, and scandalous tissue of lies....

According to Jefferson Davis, then a U.S. Senator from Mississippi, and future President of the Confederate States of America, the case merely "presented the question whether Cuffee [a derogatory term for a black person] should be kept in his normal condition or not . . . [and] whether the Congress of the United States could decide what might or might not be property in a Territory-the case being that of an officer of the army sent into a Territory to perform his public duty, having taken with him his negro slave".

Irene Emerson moved to Massachusetts in 1850 and married Calvin C. Chaffee, a doctor and abolitionist who was elected to Congress on the Know Nothing and Republican tickets. Following the Supreme Court ruling, pro-slavery newspapers attacked Chaffee as a hypocrite. Chaffee protested that Dred Scott belonged to his brother-in-law and that he had nothing to do with Scott's enslavement. Nevertheless, the Chaffees executed a deed transferring the Scott family to Henry Taylor Blow, the son of Scott's former owner, Peter Blow. Chaffee's lawyer suggested the transfer as the most convenient way of freeing Scott since Missouri law required manumitters to appear in person before the court.

Taylor Blow filed the manumission papers with Judge Hamilton on May 26, 1857. The emancipation of Dred Scott and his family was national news and was celebrated in northern cities. Scott worked as a porter in a hotel in St. Louis, where he was a minor celebrity. His wife took in laundry. Dred Scott died of tuberculosis on November 7, 1858. Harriet died on June 17, 1876.

Economist Charles Calomiris and historian Larry Schweikart discovered that uncertainty about whether the entire West would suddenly become slave territory or engulfed in combat like " Bleeding Kansas" gripped the markets immediately. The east-west railroads collapsed immediately (although north-south lines were unaffected), causing, in turn, the near-collapse of several large banks and the runs that ensued. What followed the runs has been called the Panic of 1857.

The Panic of 1857, unlike the Panic of 1837, almost exclusively impacted the North, a fact that Calomiris and Schweikart attribute to the South's system of branch banking, as opposed to the North's system of unit banking. In the South's branch banking system, information moved reliably among the branch banks and transmission of the panic was minor. Northern unit banks, in contrast, were competitors and seldom shared such vital information.

Southerners, who had grown uncomfortable with the Kansas-Nebraska Act, argued that they had a constitutional right to bring slaves into the territories, regardless of any decision by a territorial legislature on the subject. The Dred Scott decision seemed to endorse that view.

Although Taney believed that the decision represented a compromise that would be a final settlement of the slavery question by transforming a contested political issue into a matter of settled law, the decision produced the opposite result. It strengthened Northern opposition to slavery, divided the Democratic Party on sectional lines, encouraged secessionist elements among Southern supporters of slavery to make bolder demands, and strengthened the Republican Party.

In 1860, the Republican Party explicitly rejected the Dred Scott verdict in their official platform, stating "the new dogma that the Constitution, of its own force, carries slavery into any or all of the territories of the United States, is a dangerous political heresy, at variance with the explicit provisions of that instrument itself, with contemporaneous exposition, and with legislative and judicial precedent; is revolutionary in its tendency, and subversive of the peace and harmony of the country."

In 1859, when defending John Anthony Copeland and Shields Green from the charge of treason, following their participation in John Brown's raid on Harpers Ferry, their attorney, George Sennott, cited the Dred Scott decision in arguing successfully that since they were not citizens according to that Supreme Court ruling, they could not commit treason. The charge of treason was dropped, but they were found guilty and executed on other charges.

Justice John Marshall Harlan was the lone dissenting vote in Plessy v. Ferguson (1896), which declared racial segregation constitutional and created the concept of " separate but equal". In his dissent, Harlan wrote that the majority's opinion would "prove to be quite as pernicious as the decision made by this tribunal in the Dred Scott case".

Charles Evans Hughes, writing in 1927 on the Supreme Court's history, described Dred Scott v. Sandford as a "self-inflicted wound" from which the court would not recover for many years.

In a memo to Justice Robert H. Jackson in 1952, for whom he was clerking, on the subject of Brown v. Board of Education, the future Chief Justice William H. Rehnquist wrote that " Scott v. Sandford was the result of Taney's effort to protect slaveholders from legislative interference."

Justice Antonin Scalia made the comparison between Planned Parenthood v. Casey (1992) and Dred Scott in an effort to see overturned:

Dred Scott ... rested upon the concept of " substantive due process" that the Court praises and employs today. Indeed, Dred Scott was very possibly the first application of substantive due process in the Supreme Court, the original precedent for... .

Scalia noted that the Dred Scott decision had been written and championed by Taney and left the justice's reputation irrevocably tarnished. Taney, who was attempting to end the disruptive question of the future of slavery, wrote a decision that "inflamed the national debate over slavery and deepened the divide that led ultimately to the American Civil War".

Chief Justice John Roberts compared Obergefell v. Hodges (2015) to Dred Scott, as another example of trying to settle a contentious issue through a ruling that went beyond the scope of the Constitution.

1977: The Scotts' great-grandson John A. Madison, Jr., an attorney, gave the invocation at the ceremony at the Old Courthouse in St. Louis, a National Historic Landmark, for the dedication of a National Historic Marker commemorating the Scotts' case tried there.

2000: Harriet and Dred Scott's petition papers in their freedom suit were displayed at the main branch of the St. Louis Public Library, following the discovery of more than 300 freedom suits in the archives of the U.S. circuit court.

2006: A new historic plaque was erected at the Old Courthouse to honor the active roles of both Dred and Harriet Scott in their freedom suit and the case's significance in U.S. history.

2012: A monument depicting Dred and Harriet Scott was erected at the Old Courthouse's east entrance facing the St. Louis Gateway Arch.

Dred Scott v. Sandford , 60 U.S. (19 How.) 393 (1857), was a landmark decision of the United States Supreme Court that held the U.S. Constitution did not extend American citizenship to people of black African descent, and thus they could not enjoy the rights and privileges the Constitution conferred upon American citizens.

The history of slavery spans many cultures, nationalities, and religions from ancient times to the present day. However the social, economic, and legal positions of slaves have differed vastly in different systems of slavery in different times and places.

Slavery occurs relatively rarely among hunter-gatherer populations because it develops under conditions of social stratification. Slavery operated in the very first civilizations (such as Sumer in Mesopotamia, which dates back as far as 3500 BCE). Slavery features in the Mesopotamian Code of Hammurabi (c. 1860 BCE), which refers to it as an established institution. Slavery became common within much of Europe during the Early Middle Ages and it continued into the following centuries. The Byzantine-Ottoman wars (1265-1479) and the Ottoman wars in Europe (14th to 20th centuries) resulted in the capture of large numbers of Christian slaves. The Dutch, French, Spanish, Portuguese, British, Arabs and a number of West African kingdoms played a prominent role in the Atlantic slave trade, especially after 1600. The Republic of Ragusa became the first European country to ban the slave trade in 1416. In modern times Denmark-Norway abolished the trade in 1802.

Although slavery is no longer legal anywhere in the world (with the exception of penal labour), human trafficking remains an international problem and an estimated 25-40 million people were enslaved as of 2013, the majority in Asia. During the 1983-2005 Second Sudanese Civil War people were taken into slavery. Evidence emerged in the late 1990s of systematic child-slavery and -trafficking on cacao plantations in West Africa. Slavery continues into the 21st century. Although Mauritania criminalized slavery in August 2007, an estimated up to 600,000 men, women and children, or 20% of the population of Mauritania, are currently enslaved, many of them used as bonded labor. Slavery in the 21st century continues, with the top ten countries with the highest prevalence according to the Global Slavery Index being North Korea, Eritrea, Burundi, the Central African Republic, Afghanistan, Mauritania, South Sudan, Pakistan, Cambodia and Iran. Islamist quasi-states such as the Islamic State of Iraq and the Levant and Boko Haram have abducted and enslaved women and children (often to serve as sex slaves).

Evidence of slavery predates written records, and has existed in many cultures. Mass slavery requires economic surpluses and a high population density to be viable. Due to these factors, the practice of slavery would have only proliferated after the invention of agriculture during the Neolithic Revolution, about 11,000 years ago.

C. 1480 BCE, fugitive slave treaty between Idrimi of Alakakh (now Tell Atchana) and Pillia of Kizzuwatna (now Cilicia).

French historian Fernand Braudel noted that slavery was endemic in Africa and part of the structure of everyday life. "Slavery came in different guises in different societies: there were court slaves, slaves incorporated into princely armies, domestic and household slaves, slaves working on the land, in industry, as couriers and intermediaries, even as traders". During the 16th century, Europe began to outpace the Arab world in the export traffic, with its slave traffic from Africa to the Americas. The Dutch imported slaves from Asia into their colony in South Africa. In 1807 Britain, which held extensive, although mainly coastal, colonial territories on the African continent (including southern Africa), made the international slave trade illegal, as did the United States in 1808.

Slavery in Ethiopia persisted until 1942. The Anti-Slavery Society estimated that there were 2,000,000 slaves in the early 1930s, out of an estimated population of between 8 and 16 million. It was finally abolished by order of emperor Haile Selassie on 26 August 1942.

When British rule was first imposed on the Sokoto Caliphate and the surrounding areas in northern Nigeria at the turn of the 20th century, approximately 2 million to 2.5 million people there were slaves. Slavery in northern Nigeria was finally outlawed in 1936.

Elikia M'bokolo, April 1998, Le Monde diplomatique. Quote: "The African continent was bled of its human resources via all possible routes. Across the Sahara, through the Red Sea, from the Indian Ocean ports and across the Atlantic. At least ten centuries of slavery for the benefit of the Muslim countries (from the ninth to the nineteenth)." He continues: "Four million slaves exported via the Red Sea, another four million through the Swahili ports of the Indian Ocean, perhaps as many as nine million along the trans-Saharan caravan route, and eleven to twenty million (depending on the author) across the Atlantic Ocean"

Zanzibar was once East Africa's main slave-trading port, and under Omani Arabs in the 19th century, as many as 50,000 slaves were passing through the city each year.

Prior to the 16th century, the bulk of slaves exported from Africa were shipped from East Africa to the Arabian peninsula. Zanzibar became a leading port in this trade. Arab slave traders differed from European ones in that they would often conduct raiding expeditions themselves, sometimes penetrating deep into the continent. They also differed in that their market greatly preferred the purchase of female slaves over male ones.

The increased presence of European rivals along the East coast led Arab traders to concentrate on the overland slave caravan routes across the Sahara from the Sahel to North Africa. The German explorer Gustav Nachtigal reported seeing slave caravans departing from Kukawa in Bornu bound for Tripoli and Egypt in 1870. The slave trade represented the major source of revenue for the state of Bornu as late as 1898. The eastern regions of the Central African Republic have never recovered demographically from the impact of 19th-century raids from the Sudan and still have a population density of less than 1 person/km². During the 1870s, European initiatives against the slave trade caused an economic crisis in northern Sudan, precipitating the rise of Mahdist forces. Mahdi's victory created an Islamic state, one that quickly reinstituted slavery.

The Middle Passage, the crossing of the Atlantic to the Americas, endured by slaves laid out in rows in the holds of ships, was only one element of the well-known triangular trade engaged in by Portuguese, Dutch, Danish-Norwegians, French, British and others. Ships having landed slaves in Caribbean ports would take on sugar, indigo, raw cotton, and later coffee, and make for Liverpool, Nantes, Lisbon or Amsterdam. Ships leaving European ports for West Africa would carry printed cotton textiles, some originally from India, copper utensils and bangles, pewter plates and pots, iron bars more valued than gold, hats, trinkets, gunpowder and firearms and alcohol. Tropical shipworms were eliminated in the cold Atlantic waters, and at each unloading, a profit was made.

While talking about the slave trade in East Africa in his journals, "To overdraw its evil is a simple impossibility."

To overdraw its evil is a simple impossibility.

David Livingstone while travelling in the African Great Lakes Region in 1866 described a trail of slaves as such:

19th June 1866 - We passed a woman tied by the neck to a tree and dead, the people of the country explained that she had been unable to keep up with the other slaves in a gang, and her master had determined that she should not become anyone's property if she recovered.
26th June. - ...We passed a slave woman shot or stabbed through the body and lying on the path: a group of men stood about a hundred yards off on one side, and another of the women on the other side, looking on; they said an Arab who passed early that morning had done it in anger at losing the price he had given for her, because she was unable to walk any longer.
27th June 1866 - To-day we came upon a man dead from starvation, as he was very thin. One of our men wandered and found many slaves with slave-sticks on, abandoned by their masters from want of food; they were too weak to be able to speak or say where they had come from; some were quite young.

The strangest disease I have seen in this country seems really to be broken-heartedness, and it attacks free men who have been captured and made slaves... Twenty one were unchained, as now safe; however all ran away at once; but eight with many others still in chains, died in three days after the crossing. They described their only pain in the heart, and placed the hand correctly on the spot, though many think the organ stands high up in the breast-bone.

African states played a role in the slave trade, and slavery was a common practice among Sub Saharan Africans before the involvement of the Arabs, Berbers and Europeans. There were three types: those who were slaves through conquest, those who were slaves due to unpaid debts, or those whose parents gave them as slaves to tribal chiefs. Chieftains would barter their slaves to Arab, Berber, Ottoman or European buyers for rum, spices, cloth or other goods. Selling captives or prisoners was commonly practiced among Africans, Turks, Berbers and Arabs during that era. However, as the Atlantic slave trade increased its demand, local systems which primarily serviced indentured servitude expanded. European slave trading, as a result, was the most pivotal change in the social, economic, cultural, spiritual, religious, political dynamics of the concept of slave trading. It ultimately undermined local economies and political stability as villages' vital labour forces were shipped overseas as slave raids and civil wars became commonplace. Crimes which were previously punishable by some other means became punishable by enslavement.

The kings of Dahomey sold their war captives into transatlantic slavery, who otherwise may have been killed in a ceremony known as the Annual Customs. As one of West Africa's principal slave states, Dahomey became extremely unpopular with neighbouring peoples. Like the Bambara Empire to the east, the Khasso kingdoms depended heavily on the slave trade for their economy. A family's status was indicated by the number of slaves it owned, leading to wars for the sole purpose of taking more captives. This trade led the Khasso into increasing contact with the European settlements of Africa's west coast, particularly the French. Benin grew increasingly rich during the 16th and 17th centuries on the slave trade with Europe; slaves from enemy states of the interior were sold, and carried to the Americas in Dutch and Portuguese ships. The Bight of Benin's shore soon came to be known as the "Slave Coast".

The slave trade is the ruling principle of my people. It is the source and the glory of their wealth...the mother lulls the child to sleep with notes of triumph over an enemy reduced to slavery...

In 1807, under internal and external pressures, the United Kingdom made illegal the international trade in slaves. The Royal Navy was deployed to prevent slavers from the United States, France, Spain, Portugal, Holland, West Africa and Arabia. The King of Bonny (now in Nigeria) allegedly became dissatisfied of the British intervention in stopping slave trading.

We think this trade must go on. That is the verdict of our oracle and the priests. They say that your country, however great, can never stop a trade ordained by God himself.

Joseph Miller states that African buyers would prefer males, but in reality, women and children would be more easily captured as men fled. Those captured would be sold for various reasons such as food, debts, or servitude. Once captured, the journey to the coast killed many and weakened others. Disease engulfed many, and insufficient food damaged those who made it to the coasts. Scurvy was so common that it was known as mal de Luanda (Luanda sickness). The assumption for those who died on the journey died from malnutrition. As food was limited, water may have been just as bad. Dysentery was widespread and poor sanitary conditions at ports did not help. Since supplies were poor, slaves were not equipped with the best clothing that further exposed to more diseases.

If the fear of disease caused terror, the psyche of slaves for being captured was just as terrifying. The most popular assumption for being captured was Europeans were cannibals. Stories and rumours spread that whites captured Africans to eat them. Olaudah Equiano accounts his experience about the sorrow slaves encountered at the ports. He talks about his first moment on a slave ship and asked if he was going to be eaten. Yet, the worst for slaves has only begun, and the journey on the water proved to be more terrifying. For every 100 Africans captured, only 64 would reach the coast, and only about 50 would reach the New World.

Others believe that slavers had a vested interest in capturing rather than killing, and in keeping their captives alive; and that this coupled with the disproportionate removal of males and the introduction of new crops from the Americas ( cassava, maize) would have limited general population decline to particular regions of western Africa around 1760-1810, and in Mozambique and neighbouring areas half a century later. There has also been speculation that within Africa, females were most often captured as brides, with their male protectors being a "bycatch" who would have been killed if there had not been an export market for them.

British explorer Mungo Park encountered a group of slaves when traveling through Mandinka country:

They were all very inquisitive, but they viewed me at first with looks of horror, and repeatedly asked if my countrymen were cannibals. They were very desirous to know what became of the slaves after they had crossed the salt water. I told them that they were employed in cultivation the land; but they would not believe me ... A deeply-rooted idea that the whites purchase negroes for the purpose of devouring them, or of selling them to others that they may be devoured hereafter, naturally makes the slaves contemplate a journey towards the coast with great terror, insomuch that the slatees are forced to keep them constantly in irons, and watch them very closely, to prevent their escape.

During the period from the late 19th century and early 20th century, demand for the labour-intensive harvesting of rubber drove frontier expansion and forced labour. The personal monarchy of Belgian King Leopold II in the Congo Free State saw mass killings and slavery to extract rubber.

Stephanie Smallwood in her book Saltwater Slavery uses Equiano's account on board ships to describe the general thoughts of most slaves.

Then," said I, "how comes it in all our country we never heard of them?" They told me because they lived so very far off. I then asked where were their women? Had they any like themselves? I was told that they had. "And why," said I, "do we not see them?" They answered, because they were left behind. I asked how the vessel could go? They told me they could not tell; but that there was cloth put upon the masts by the help of the ropes I saw, and then the vessel went on; and the white men had some spell or magic they put in the water when they liked, in order to stop the vessel. I was exceedingly amazed at this account, and really thought they were spirits. I there-fore wished much to be from amongst them, for I expected they would sacrifice me; but my wishes were vain-for we were so quartered that it was impossible for any of us to make our escape.

Accounts like these raised many questions as some slaves grew philosophical with their journey. Smallwood points out the challenges for slaves were physical and metaphysical. The physical would be obvious as the challenge to overcome capacity, lack of ship room, and food. The metaphysical was unique as the open sea would challenge African slaves' vision of the ocean as habitable. At essence, the journey on the ocean would prove to be an African's biggest fear that would keep them in awe. Combining this with the lack of knowledge of the sea, Africans would be entering a world of anxiety never seen before. Yet, Europeans were also fearful of the sea, but not to the extent of Africans. One of these dilemmas came with the sense of time. Africans used seasonal weather to predict time and days. The moon was a sense of time, but used like in other cultures. On the sea, Africans used the moon to best count the days, but the sea did not provide seasonal changes for them to know how long they were at sea. Counting the days on a ship was not the main priority, however. Surviving the voyage was the main horror. No one escaped diseases as the close quarters infected everyone including the crew. Death was so common that ships were called tumbeiros or floating tombs. What shocked Africans the most was how death was handled in the ships. Smallwood says the traditions for an African death was delicate and community-based. On ships, bodies would be thrown into the sea. Because the sea represented bad omens, bodies in the sea represented a form of purgatory and the ship a form of hell. In the end, the Africans who made the journey would have survived disease, malnutrition, confined space, close death, and the trauma of the ship.

In Algiers during the time of the Regency of Algiers in North Africa in the 19th century, 1.5 million Christians and Europeans were captured and forced into slavery. This eventually led to the Bombardment of Algiers in 1816 by the British and Dutch, forcing the Dey of Algiers to free many slaves.

The trading of children has been reported in modern Nigeria and Benin. In parts of Ghana, a family may be punished for an offense by having to turn over a virgin female to serve as a sex slave within the offended family. In this instance, the woman does not gain the title or status of "wife". In parts of Ghana, Togo, and Benin, shrine slavery persists, despite being illegal in Ghana since 1998. In this system of ritual servitude, sometimes called trokosi (in Ghana) or voodoosi in Togo and Benin, young virgin girls are given as slaves to traditional shrines and are used sexually by the priests in addition to providing free labor for the shrine.

An article in the Middle East Quarterly in 1999 reported that slavery is endemic in Sudan. Estimates of abductions during the Second Sudanese Civil War range from 14,000 to 200,000 people.

During the Second Sudanese Civil War people were taken into slavery; estimates of abductions range from 14,000 to 200,000. Abduction of Dinka women and children was common. In Mauritania it is estimated that up to 600,000 men, women and children, or 20% of the population, are currently enslaved, many of them used as bonded labor. Slavery in Mauritania was criminalized in August 2007.

During the Darfur conflict that began in 2003, many people were kidnapped by Janjaweed and sold into slavery as agricultural labor, domestic servants and sex slaves.

In Niger, slavery is also a current phenomenon. A Nigerien study has found that more than 800,000 people are enslaved, almost 8% of the population. Niger installed an anti-slavery provision in 2003. In a landmark ruling in 2008, the ECOWAS Community Court of Justice declared that the Republic of Niger failed to protect Hadijatou Mani Koraou from slavery, and awarded Mani CFA 10,000,000 (approximately US$20,000) in reparations.

Sexual slavery and forced labor are common in the Democratic Republic of Congo.

Many pygmies in the Republic of Congo and Democratic Republic of Congo belong from birth to Bantus in a system of slavery.

Evidence emerged in the late 1990s of systematic slavery in cacao plantations in West Africa; see the chocolate and slavery article.

On the night of 14-15 April 2014, a group of militants attacked the Government Girls Secondary School in Chibok, Nigeria. They broke into the school, pretending to be guards, telling the girls to get out and come with them. A large number of students were taken away in trucks, possibly into the Konduga area of the Sambisa Forest where Boko Haram were known to have fortified camps. Houses in Chibok were also burned down in the incident. According to police, approximately 276 children were taken in the attack, of whom 53 had escaped as of 2 May. Other reports said that 329 girls were kidnapped, 53 had escaped and 276 were still missing. The students have been forced to convert to Islam and into marriage with members of Boko Haram, with a reputed " bride price" of ₦2,000 each ($12.50/ £7.50). Many of the students were taken to the neighbouring countries of Chad and Cameroon, with sightings reported of the students crossing borders with the militants, and sightings of the students by villagers living in the Sambisa Forest, which is considered a refuge for Boko Haram.

On 5 May 2014 a video in which Boko Haram leader Abubakar Shekau claimed responsibility for the kidnappings emerged. Shekau claimed that "Allah instructed me to sell them...I will carry out his instructions" and "[s]lavery is allowed in my religion, and I shall capture people and make them slaves." He said the girls should not have been in school and instead should have been married since girls as young as nine are suitable for marriage.

During the Second Libyan Civil War Libyans started capturing some of the Sub-Saharan African migrants trying to get to Europe through Libya and selling them on slave markets. Slaves are often ransomed to their families and in the meantime until ransom can be paid, they may be tortured, forced to work, sometimes worked to death, and eventually they may be executed or left to starve if the payment has not been made after a period of time. Women are often raped and used as sex slaves and sold to brothels.

Many child migrants also suffer from abuse and child rape in Libya.

In Pre-Columbian Mesoamerica the most common forms of slavery were those of prisoners of war and debtors. People unable to pay back debts could be sentenced to work as slaves to the persons owed until the debts were worked off. Warfare was important to Maya society, because raids on surrounding areas provided the victims required for human sacrifice, as well as slaves for the construction of temples. Most victims of human sacrifice were prisoners of war or slaves. Slavery was not usually hereditary; children of slaves were born free. In the Inca Empire, workers were subject to a in lieu of taxes which they paid by working for the government. Each , or extended family, would decide which family member to send to do the work. It is unclear if this labor draft or corvée counts as slavery. The Spanish adopted this system, particularly for their silver mines in Bolivia.

Other slave-owning societies and tribes of the New World were, for example, the Tehuelche of Patagonia, the Comanche of Texas, the Caribs of Dominica, the Tupinambá of Brazil, the fishing societies, such as the Yurok, that lived along the coast from what is now Alaska to California, the Pawnee and Klamath. Many of the indigenous peoples of the Pacific Northwest Coast, such as the Haida and Tlingit, were traditionally known as fierce warriors and slave-traders, raiding as far as California. Slavery was hereditary, the slaves being prisoners of war. Among some Pacific Northwest tribes about a quarter of the population were slaves. One slave narrative was composed by an Englishman, John R. Jewitt, who had been taken alive when his ship was captured in 1802; his memoir provides a detailed look at life as a slave, and asserts that a large number were held.

During the period from the late 19th century and early 20th century, demand for the labor-intensive harvesting of rubber drove frontier expansion and slavery in Latin America and elsewhere. Indigenous peoples were enslaved as part of the rubber boom in Ecuador, Peru, Colombia, and Brazil. In Central America, rubber tappers participated in the enslavement of the indigenous Guatuso-Maleku people for domestic service.

Slavery was a mainstay of the Brazilian colonial economy, especially in mining and sugarcane production. 35.3% of all slaves involved in the Atlantic Slave trade went to Brazil. 4 million slaves were obtained by Brazil, 1.5 million more than any other country. Starting around 1550, the Portuguese began to trade African slaves to work the sugar plantations, once the native Tupi people deteriorated. Although Portuguese Prime Minister Sebastião José de Carvalho e Melo, 1st Marquis of Pombal abolished slavery in mainland Portugal on 12 February 1761, slavery continued in her overseas colonies. Slavery was practiced among all classes. Slaves were owned by upper and middle classes, by the poor, and even by other slaves.

From São Paulo, the Bandeirantes, adventurers mostly of mixed Portuguese and native ancestry, penetrated steadily westward in their search for Indian slaves. Along the Amazon river and its major tributaries, repeated slaving raids and punitive attacks left their mark. One French traveler in the 1740s described hundreds of miles of river banks with no sign of human life and once-thriving villages that were devastated and empty. In some areas of the Amazon Basin, and particularly among the Guarani of southern Brazil and Paraguay, the Jesuits had organized their Jesuit Reductions along military lines to fight the slavers. In the mid-to-late 19th century, many Amerindians were enslaved to work on rubber plantations.

Escaped slaves formed Maroon communities which played an important role in the histories of Brazil and other countries such as Suriname, Puerto Rico, Cuba, and Jamaica. In Brazil, the Maroon villages were called palenques or quilombos. Maroons survived by growing vegetables and hunting. They also raided plantations. At these attacks, the maroons would burn crops, steal livestock and tools, kill slavemasters, and invite other slaves to join their communities.

Jean-Baptiste Debret, a French painter who was active in Brazil in the first decades of the 19th century, started out with painting portraits of members of the Brazilian Imperial family, but soon became concerned with the slavery of both blacks and indigenous inhabitants. His paintings on the subject (two appear on this page) helped bring attention to the subject in both Europe and Brazil itself.

The Clapham Sect, a group of evangelical reformers, campaigned during much of the 19th century for Britain to use its influence and power to stop the traffic of slaves to Brazil. Besides moral qualms, the low cost of slave-produced Brazilian sugar meant that British colonies in the West Indies were unable to match the market prices of Brazilian sugar, and each Briton was consuming 16 pounds (7 kg) of sugar a year by the 19th century. This combination led to intensive pressure from the British government for Brazil to end this practice, which it did by steps over several decades.

Brazil's 1877-78 Grande Seca (Great Drought) in the cotton-growing northeast led to major turmoil, starvation, poverty and internal migration. As wealthy plantation holders rushed to sell their slaves south, popular resistance and resentment grew, inspiring numerous emancipation societies. They succeeded in banning slavery altogether in the province of Ceará by 1884. Slavery was legally ended nationwide on 13 May by the ("Golden Law") of 1888. It was an institution in decadence at these times, as since the 1880s the country had begun to use European immigrant labor instead. Brazil was the last nation in the Western Hemisphere to abolish slavery.

Slavery was commonly used in the parts of the Caribbean controlled by France and the British Empire. The Lesser Antilles islands of Barbados, St. Kitts, Antigua, Martinique and Guadeloupe, which were the first important slave societies of the Caribbean, began the widespread use of African slaves by the end of the 17th century, as their economies converted from sugar production.

England had multiple sugar islands in the Caribbean, especially Jamaica, Barbados, Nevis, and Antigua, which provided a steady flow of sugar sales; slave labor produced the sugar. By the 1700s, there were more slaves in Barbados than all the colonies combined. Since Barbados did not have many mountains, the British were able to clear land for sugar cane. Indentured servants were initially sent to Barbados to work in the sugar fields. These indentured servants were treated so poorly that future indentured servants stopped going to Barbados, and there were not enough people to work the fields. This is when the British started bringing in African slaves. It was important for the slaves to be in Barbados because sugar had become a necessity for most people and the demand for it was high.

An important result of Britain's victory in the War of the Spanish Succession (1702-1714) was enlarging its role in the slave trade. Of special importance was the successful secret negotiation with France to obtain thirty-year monopoly on the Spanish slave trade, called the Queen Anne of Great Britain also allowed her North American colonies like Virginia to make laws that promoted black slavery. Anne had secretly negotiated with France to get its approval regarding the Asiento. She boasted to Parliament of her success in taking the Asiento away from France and London celebrated her economic coup. Most of the slave trade involved sales to Spanish colonies in the Caribbean, and to Mexico, as well as sales to British colonies in the Caribbean and in North America. Historian Vinita Ricks says the agreement allotted Queen Anne "22.5% (and King Philip V, of Spain 28%) of all profits collected for her personal fortune." Ricks concludes that the Queen's "connection to slave trade revenue meant that she was no longer a neutral observer. She had a vested interest in what happened on slave ships."

By 1778, the French were importing approximately 13,000 Africans for enslavement yearly to the French West Indies.

To regularise slavery, in 1685 Louis XIV had enacted the , which accorded certain human rights to slaves and responsibilities to the master, who was obliged to feed, clothe and provide for the general well-being of his slaves. Free blacks owned one-third of the plantation property and one-quarter of the slaves in Saint Domingue (later Haiti). Slavery in the French First Republic was abolished on 4 February 1794. When it became clear that Napoleon intended to re-establish slavery in Haiti, Dessalines and Pétion switched sides, in October 1802. On 1 January 1804, Jean-Jacques Dessalines, the new leader under the dictatorial 1801 constitution, declared Haiti a free republic. Thus Haiti became the second independent nation in the Western Hemisphere, after the United States, and the only successful slave rebellion in world history.

Whitehall in England announced in 1833 that slaves in its territories would be totally freed by 1840. In the meantime, the government told slaves they had to remain on their plantations and would have the status of "apprentices" for the next six years.

In Port-of-Spain, Trinidad, on 1 August 1834, an unarmed group of mainly elderly Negroes being addressed by the Governor at Government House about the new laws, began chanting: "Pas de six ans. Point de six ans" ("Not six years. No six years"), drowning out the voice of the Governor. Peaceful protests continued until a resolution to abolish apprenticeship was passed and de facto freedom was achieved. Full emancipation for all was legally granted ahead of schedule on 1 August 1838, making Trinidad the first British colony with slaves to completely abolish slavery.

In late August 1619, the frigate , a privateer ship owned by Robert Rich, 2nd Earl of Warwick, but flying a Dutch flag arrived at Point Comfort, Virginia (several miles downstream from the colony of Jamestown, Virginia) with the first recorded slaves from Africa to Virginia. The approximately 20 Africans were from the present-day Angola. They had been removed by the White Lion's crew from a Portuguese slave ship, the São João Bautista.

Only a fraction of the enslaved Africans brought to the New World came to British North America, perhaps as little as 5% of the total. The vast majority of slaves were sent to the Caribbean sugar colonies, Brazil, or Spanish America.

By the 1680s, with the consolidation of England's Royal African Company, enslaved Africans were arriving in English colonies in larger numbers, and the institution continued to be protected by the British government. Colonists now began purchasing slaves in larger numbers.

1640: Virginia courts sentence John Punch to lifetime slavery, marking the earliest legal sanctioning of slavery in English colonies.

1641: Massachusetts legalizes slavery.

1650: Connecticut legalizes slavery.

1654: Virginia sanctions "the right of Negros to own slaves of their own race" after African Anthony Johnson, former indentured servant, sued to have fellow African John Casor declared not an indentured servant but "slave for life."

1661: Virginia officially recognizes slavery by statute.

1662: A Virginia statute declares that children born would have the same status as their mother.

1663: Maryland legalizes slavery.

1664: Slavery is legalized in New York and New Jersey.

1670: Carolina (later, South Carolina and North Carolina) is founded mainly by planters from the overpopulated British sugar island colony of Barbados, who brought relatively large numbers of African slaves from that island.

The shift from indentured servants to African slaves was prompted by a dwindling class of former servants who had worked through the terms of their indentures and thus became competitors to their former masters. These newly freed servants were rarely able to support themselves comfortably, and the tobacco industry was increasingly dominated by large planters. This caused domestic unrest culminating in Bacon's Rebellion. Eventually, chattel slavery became the norm in regions dominated by plantations.

Several local slave rebellions took place during the 17th and 18th centuries: Gloucester County, Virginia Revolt (1663); New York Slave Revolt of 1712; Stono Rebellion (1739); and New York Slave Insurrection of 1741.

Within the British Empire, the Massachusetts courts began to follow England when, in 1772, England became the first country in the world to outlaw the slave trade within its borders (see Somerset v Stewart) followed by the Knight v. Wedderburn decision in Scotland in 1778. Between 1764 and 1774, seventeen slaves appeared in Massachusetts courts to sue their owners for freedom. In 1766, John Adams' colleague Benjamin Kent won the first trial in the present-day United States to free a slave (Slew vs. Whipple).

The Republic of Vermont banned slavery in its constitution of 1777 and continued the ban when it entered the United States in 1791. Through the Northwest Ordinance of 1787 under the Congress of the Confederation, slavery was prohibited in the territories north west of the Ohio River. By 1804, abolitionists succeeded in passing legislation that ended legal slavery in every northern state (with slaves above a certain age legally transformed to indentured servants). Congress banned the international importation or export of slaves on 1 January 1808; but not the internal slave trade.

Despite the actions of abolitionists, free blacks were subject to racial segregation in the Northern states. While England did not ban slavery in present-day Canada until 1833, free blacks found refugee and liberty there after the America Revolution and again after the War of 1812. Slavery in Canada was largely ended by judicial court decisions by the early nineteenth century. Refugees from slavery fled the South across the Ohio River to the North via the Underground Railroad. Midwestern state governments asserted States Rights arguments to refuse federal jurisdiction over fugitives. Some juries exercised their right of jury nullification and refused to convict those indicted under the Fugitive Slave Act of 1850.

After the passage of the Kansas-Nebraska Act in 1854, armed conflict broke out in Kansas Territory, where the question of whether it would be admitted to the Union as a slave state or a free state had been left to the inhabitants. The radical abolitionist John Brown was active in the mayhem and killing in " Bleeding Kansas." The true turning point in public opinion is better fixed at the Lecompton Constitution fraud. Pro-slavery elements in Kansas had arrived first from Missouri and quickly organized a territorial government that excluded abolitionists. Through the machinery of the territory and violence, the pro-slavery faction attempted to force an unpopular pro-slavery constitution through the state. This infuriated Northern Democrats, who supported popular sovereignty, and was exacerbated by the Buchanan administration reneging on a promise to submit the constitution to a referendum-which would surely fail. Anti-slavery legislators took office under the banner of the newly formed Republican Party. The Supreme Court in the Dred Scott decision of 1857 asserted that one could take one's property anywhere, even if one's property was chattel and one crossed into a free territory. It also asserted that African Americans could not be federal citizens. Outraged critics across the North denounced these episodes as the latest of the Slave Power (the politically organized slave owners) taking more control of the nation.

The slave population in the United States stood at four million. Ninety-five percent of blacks lived in the South, comprising one third of the population there as opposed to 1% of the population of the North. The central issue in politics in the 1850s involved the extension of slavery into the western territories, which settlers from the Northern states opposed. The Whig Party split and collapsed on the slavery issue, to be replaced in the North by the new Republican Party, which was dedicated to stopping the expansion of slavery. Republicans gained a majority in every northern state by absorbing a faction of anti-slavery Democrats, and warning that slavery was a backward system that undercut democracy and economic modernization. Numerous compromise proposals were put forward, but they all collapsed. A majority of Northern voters were committed to stopping the expansion of slavery, which they believed would ultimately end slavery. Southern voters were overwhelmingly angry that they were being treated as second-class citizens. In the election of 1860, the Republicans swept Abraham Lincoln into the Presidency and his party took control (with only 39.8% of the popular vote) and legislators into Congress. The states of the deep South, convinced that the economic power of what they called " King Cotton" would overwhelm the North and win support from Europe voted to seceded from the U.S. (the Union). They formed the Confederate States of America, based on the promise of maintaining slavery. War broke out in April 1861, as both sides sought wave after wave of enthusiasm among young men volunteering to form new regiments and new armies. In the North, the main goal was to preserve the union as an expression of American nationalism.

By 1862 most northern leaders realized that the mainstay of Southern secession, slavery, had to be attacked head-on. All the border states rejected President Lincoln's proposal for compensated emancipation. However, by 1865 all had begun the abolition of slavery, except Kentucky and Delaware. The Emancipation Proclamation was an executive order issued by Lincoln on 1 January 1863. In a single stroke, it changed the legal status, as recognized by the U.S. government, of 3 million slaves in designated areas of the Confederacy from "slave" to "free." It had the practical effect that as soon as a slave escaped the control of the Confederate government, by running away or through advances of federal troops, the slave became legally and actually free. Plantation owners, realizing that emancipation would destroy their economic system, sometimes moved their slaves as far as possible out of reach of the Union army. By June 1865, the Union Army controlled all of the Confederacy and liberated all of the designated slaves. The owners were never compensated. Over 200,000 free blacks and newly freed slaves fought for the Union in the Army and Navy, thereby validating their claims to full citizenship.

The severe dislocations of war and Reconstruction had a severe negative impact on the black population, with a large amount of sickness and death. After liberation, many of the Freedmen remained on the same plantation. Others fled or crowded into refugee camps operated by the Freedmen's Bureau. The Bureau provided food, housing, clothing, medical care, church services, some schooling, legal support, and arranged for labor contracts. Fierce debates about the rights of the Freedmen, and of the defeated Confederates, often accompanied by killings of black leaders, marked the Reconstruction Era, 1863-77.

Slavery was never reestablished, but after 1877, white Democrats took control of all the southern states and blacks lost nearly all the political power they had achieved during Reconstruction. By 1900 they also lost the right to vote. They had become second class citizens. The great majority lived in the rural South in poverty working as laborers, sharecroppers or tenant farmers; a small proportion owned their own land. The black churches, especially the Baptist Church, was the center of community activity and leadership.

Slavery in the Middle East first developed out of the slavery practices of the Ancient Near East, and these practices were radically different at times, depending on social-political factors such as the Arab slave trade. Two rough estimates by scholars of the number of slaves held over twelve centuries in Muslim lands are 11.5 million and 14 million.

Under Sharia (Islamic law), children of slaves or prisoners of war could become slaves but only non-Muslims. Manumission of a slave was encouraged as a way of expiating sins. Many early converts to Islam, such as Bilal ibn Rabah al-Habashi, were the poor and former slaves. In theory, slavery in Islamic law does not have a racial or color component, although this has not always been the case in practice.

Bernard Lewis writes: "In one of the sad paradoxes of human history, it was the humanitarian reforms brought by Islam that resulted in a vast development of the slave trade inside, and still more outside, the Islamic empire." He notes that the Islamic injunctions against the enslavement of Muslims led to massive importation of slaves from the outside. According to Patrick Manning, Islam by recognizing and codifying the slavery seems to have done more to protect and expand slavery than the reverse.

Slavery was a legal and important part of the economy of the Ottoman Empire and Ottoman society until the slavery of Caucasians was banned in the early 19th century, although slaves from other groups were allowed. In Constantinople (present-day Istanbul), the administrative and political center of the Empire, about a fifth of the population consisted of slaves in 1609. Even after several measures to ban slavery in the late 19th century, the practice continued largely unfazed into the early 20th century. As late as 1908, female slaves were still sold in the Ottoman Empire. Sexual slavery was a central part of the Ottoman slave system throughout the history of the institution.

A member of the Ottoman slave class, called a in Turkish, could achieve high status. Harem guards and janissaries are some of the better-known positions a slave could hold, but slaves were actually often at the forefront of Ottoman politics. The majority of officials in the Ottoman government were bought slaves, raised free, and integral to the success of the Ottoman Empire from the 14th century into the 19th. Many officials themselves owned a large number of slaves, although the Sultan himself owned by far the largest amount. By raising and specially training slaves as officials in palace schools such as Enderun, the Ottomans created administrators with intricate knowledge of government and fanatic loyalty.

Ottomans practiced , a sort of "blood tax" or "child collection", young Christian boys from the Balkans and Anatolia were taken from their homes and families, brought up as Muslims, and enlisted into the most famous branch of the , the Janissaries, a special soldier class of the Ottoman army that became a decisive faction in the Ottoman invasions of Europe.

During the various 18th and 19th century persecution campaigns against Christians as well as during the culminating Assyrian, Armenian and Greek genocides of World War I, many indigenous Armenian, Assyrian and Greek Christian women and children were carried off as slaves by the Ottoman Turks and their Kurdish allies. Henry Morgenthau, Sr., U.S. Ambassador in Constantinople from 1913 to 1916, reports in his Ambassador Morgenthau's Story that there were gangs trading white slaves during his term in Constantinople. He also reports that Armenian girls were sold as slaves during the Armenian Genocide.

The Arab or Islamic slave trade lasted much longer than the Atlantic or European slave trade: "It began in the middle of the seventh century and survives today in Mauritania and Sudan. With the Islamic slave trade, we're talking of 14 centuries rather than four." Further, "whereas the gender ratio of slaves in the Atlantic trade was two males to every female, in the Islamic trade, it was two females to every male," according to Ronald Segal

According to media reports from late 2014 the Islamic State of Iraq and the Levant (ISIL) was selling Yazidi and Christian women as slaves. According to Haleh Esfandiari of the Woodrow Wilson International Center for Scholars, after ISIL militants have captured an area "[t]hey usually take the older women to a makeshift slave market and try to sell them." In mid-October 2014, the UN estimated that 5,000 to 7,000 Yazidi women and children were abducted by ISIL and sold into slavery. In the digital magazine , ISIL claimed religious justification for enslaving Yazidi women whom they consider to be from a heretical sect. ISIL claimed that the Yazidi are idol worshipers and their enslavement is part of the old shariah practice of spoils of war. According to The Wall Street Journal, ISIL appeals to apocalyptic beliefs and claims "justification by a Hadith that they interpret as portraying the revival of slavery as a precursor to the end of the world".

ISIL announced the revival of slavery as an institution. In 2015 the official slave prices set by ISIL were following:

Children aged 1 to 9 were sold for 200,000 dinars ($169).

Women and children 10 to 20 years old for 150,000 dinars ($127).

Women 20 to 30 years old for 100,000 dinar ($85).

Women 30 to 40 years old are 75,000 dinar ($63).

Women 40 to 50 years old for 50,000 dinar ($42).

However some slaves have been sold for as little as a pack of cigarettes. Sex slaves were sold to Saudi Arabia, other Persian Gulf states and Turkey.

Slavery has existed all throughout Asia, and forms of slavery still exist today.

Scholars differ as to whether or not slaves and the institution of slavery existed in ancient India. These English words have no direct, universally accepted equivalent in Sanskrit or other Indian languages, but some scholars translate the word , mentioned in texts like Manu Smriti, as slaves. Ancient historians who visited India offer the closest insights into the nature of Indian society and slavery in other ancient civilizations. For example, the Greek historian Arrian, who chronicled India about the time of Alexander the Great, wrote in his Indika,

The Indians do not even use aliens as slaves, much less a countryman of their own.

Qin dynasty (221-206 BC) Men sentenced to castration became eunuch slaves of the Qin dynasty state and as a result they were made to do forced labor, on projects like the Terracotta Army. The Qin government confiscated the property and enslaved the families of those who received castration as a punishment for rape.
Slaves were deprived of their rights and connections to their families.

Han dynasty (206 BC - 220 AD) One of Emperor Gao's first acts was to set free from slavery agricultural workers who were enslaved during the Warring States period, although domestic servants retained their status.

Men punished with castration during the Han dynasty were also used as slave labor.

Deriving from earlier Legalist laws, the Han dynasty set in place rules that the property of and families of criminals doing three years of hard labor or sentenced to castration were to have their families seized and kept as property by the government.

During the millennium long Chinese domination of Vietnam, Vietnam was a great source of slave girls who were used as sex slaves in China. The slave girls of Viet were even eroticized in Tang dynasty poetry.

The Islamic invasions, starting in the 8th century, also resulted in hundreds of thousands of Indians being enslaved by the invading armies, one of the earliest being the armies of the Umayyad commander Muhammad bin Qasim. Qutb-ud-din Aybak, a Turkic slave of Muhammad Ghori rose to power following his master's death. For almost a century, his descendants ruled North-Central India in form of Slave Dynasty. Several slaves were also brought to India by the Indian Ocean trades; for example, the Siddi are descendants of Bantu slaves brought to India by Arab and Portuguese merchants.

Andre Wink summarizes the slavery in 8th and 9th century India as follows,

(During the invasion of Muhammad al-Qasim), invariably numerous women and children were enslaved. The sources insist that now, in dutiful conformity to religious law, 'the one-fifth of the slaves and spoils' were set apart for the caliph's treasury and despatched to Iraq and Syria. The remainder was scattered among the army of Islam. At Rūr, a random 60,000 captives reduced to slavery. At Brahamanabad 30,000 slaves were allegedly taken. At Multan 6,000. Slave raids continued to be made throughout the late Umayyad period in Sindh, but also much further into Hind, as far as Ujjain and Malwa. The Abbasid governors raided Punjab, where many prisoners and slaves were taken.

In the early 11th century Tarikh al-Yamini, the Arab historian Al-Utbi recorded that in 1001 the armies of Mahmud of Ghazna conquered Peshawar and Waihand (capital of Gandhara) after Battle of Peshawar (1001), "in the midst of the land of Hindustan", and captured some 100,000 youths. Later, following his twelfth expedition into India in 1018-19, Mahmud is reported to have returned with such a large number of slaves that their value was reduced to only two to ten dirhams each. This unusually low price made, according to Al-Utbi, "merchants [come] from distant cities to purchase them, so that the countries of Central Asia, Iraq and Khurasan were swelled with them, and the fair and the dark, the rich and the poor, mingled in one common slavery". Elliot and Dowson refer to "five hundred thousand slaves, beautiful men and women.". Later, during the Delhi Sultanate period (1206-1555), references to the abundant availability of low-priced Indian slaves abound. Levi attributes this primarily to the vast human resources of India, compared to its neighbors to the north and west (India's Mughal population being approximately 12 to 20 times that of Turan and Iran at the end of the 16th century).

Slavery and empire-formation tied in particularly well with iqta and it is within this context of Islamic expansion that elite slavery was later commonly found. It became the predominant system in North India in the thirteenth century and retained considerable importance in the fourteenth century. Slavery was still vigorous in fifteenth-century Bengal, while after that date it shifted to the Deccan where it persisted until the seventeenth century. It remained present to a minor extent in the Mughal provinces throughout the seventeenth century and had a notable revival under the Afghans in North India again in the eighteenth century.

The Delhi sultanate obtained thousands of slaves and eunuch servants from the villages of Eastern Bengal (a widespread practice which Mughal emperor Jahangir later tried to stop). Wars, famines, pestilences drove many villagers to sell their children as slaves. The Muslim conquest of Gujarat in Western India had two main objectives. The conquerors demanded and more often forcibly wrested both land owned by Hindus and Hindu women. Enslavement of women invariably led to their conversion to Islam. In battles waged by Muslims against Hindus in Malwa and Deccan plateau, a large number of captives were taken. Muslim soldiers were permitted to retain and enslave POWs as plunder.

The first Bahmani sultan, Alauddin Bahman Shah is noted to have captured 1,000 singing and dancing girls from Hindu temples after he battled the northern Carnatic chieftains. The later Bahmanis also enslaved civilian women and children in wars; many of them were converted to Islam in captivity. About the Mughal empire, W.H. Moreland observed, "it became a fashion to raid a village or group of villages without any obvious justification, and carry off the inhabitants as slaves."

During the rule of Shah Jahan, many peasants were compelled to sell their women and children into slavery to meet the land revenue demand. Slavery was officially abolished in British India by the Indian Slavery Act, 1843. However, in modern India, Pakistan and Nepal, there are millions of bonded laborers, who work as slaves to pay off debts.

The Tang dynasty purchased Western slaves from the Radanite Jews. Tang Chinese soldiers and pirates enslaved Koreans, Turks, Persians, Indonesians, and people from Inner Mongolia, Central Asia, and northern India. The greatest source of slaves came from southern tribes, including Thais and aboriginals from the southern provinces of Fujian, Guangdong, Guangxi, and Guizhou. Malays, Khmers, Indians, and black Africans were also purchased as slaves in the Tang dynasty. Slavery was prevalent until the late 19th century and early 20th century China. All forms of slavery have been illegal in China since 1910.

Slavery in Japan was, for most of its history, indigenous, since the export and import of slaves was restricted by Japan being a group of islands. In late-16th-century Japan, slavery was officially banned; but forms of contract and indentured labor persisted alongside the period penal codes' forced labor. During the Second Sino-Japanese War and the Pacific War, the Japanese military used millions of civilians and prisoners of war from several countries as forced laborers.

In Korea, slavery was officially abolished with the Gabo Reform of 1894. During the Joseon period, in times of poor harvest and famine, many peasants voluntarily sold themselves into the nobi system in order to survive.

In Southeast Asia, there was a large slave class in Khmer Empire who built the enduring monuments in Angkor Wat and did most of the heavy work. Between the 17th and the early 20th centuries one-quarter to one-third of the population of some areas of Thailand and Burma were slaves. By the 19th century, Bhutan had developed a slave trade with Sikkim and Tibet, also enslaving British subjects and Brahmins. According to the International Labour Organization (ILO), during the early 21st century an estimated 800,000 people are subject to forced labor in Myanmar.

Slavery in pre-Spanish Philippines was practiced by the tribal Austronesian peoples who inhabited the culturally diverse islands. The neighbouring Muslim states conducted slave raids from the 1600s into the 1800s in coastal areas of the Gulf of Thailand and the Philippine islands. Slaves in Toraja society in Indonesia were family property. People would become slaves when they incurred a debt. Slaves could also be taken during wars, and slave trading was common. Torajan slaves were sold and shipped out to Java and Siam. Slaves could buy their freedom, but their children still inherited slave status. Slavery was abolished in 1863 in all Dutch colonies.

Records of slavery in Ancient Greece go as far back as Mycenaean Greece. The origins are not known, but it appears that slavery became an important part of the economy and society only after the establishment of cities. Slavery was common practice and an integral component of ancient Greece, as it was in other societies of the time, including ancient Israel. It is estimated that in Athens, the majority of citizens owned at least one slave. Most ancient writers considered slavery not only natural but necessary, but some isolated debate began to appear, notably in Socratic dialogues. The Stoics produced the first condemnation of slavery recorded in history.

During the 8th and the 7th centuries BC, in the course of the two Messenian Wars, the Spartans reduced an entire population to a pseudo-slavery called . According to Herodotus (IX, 28-29), helots were seven times as numerous as Spartans. Following several helot revolts around the year 600 BC, the Spartans restructured their city-state along authoritarian lines, for the leaders decided that only by turning their society into an armed camp could they hope to maintain control over the numerically dominant helot population. In some Ancient Greek city-states, about 30% of the population consisted of slaves, but paid and slave labor seem to have been equally important.

Romans inherited the institution of slavery from the Greeks and the Phoenicians. As the Roman Republic expanded outward, it enslaved entire populations, thus ensuring an ample supply of laborers to work in Rome's farms, quarries and households. The people subjected to Roman slavery came from all over Europe and the Mediterranean. Such oppression by an elite minority eventually led to slave revolts; the Third Servile War led by Spartacus was the most famous and severe. Greeks, Berbers, Germans, Britons, Slavs, Thracians, Gauls (or Celts), Jews, Arabs and many more ethnic groups were enslaved to be used for labor, and also for amusement (e.g. gladiators and sex slaves). If a slave ran away, they were liable to be crucified.

The overall impact of slavery on the Italian genetics was insignificant though, because the slaves imported in Italy were native Europeans, and very few if any of them had extra European origin. This has been further confirmed by recent biochemical analysis of 166 skeletons from three non-elite imperial-era cemeteries in the vicinity of Rome (where the bulk of the slaves lived), which shows that only 1 individual definitely came from outside of Europe (North Africa), and another 2 possibly did, but results are inconclusive. In the rest of the Italian peninsula, the amount of non European slaves was definitively much lower than that.

The chaos of invasion and frequent warfare also resulted in victorious parties taking slaves throughout Europe in the early Middle Ages. St. Patrick, himself captured and sold as a slave, protested against an attack that enslaved newly baptized Christians in his "Letter to the Soldiers of Coroticus". As a commonly traded commodity, like cattle, slaves could become a form of internal or trans-border currency. Slavery during the Early Middle Ages had several distinct sources.

The Vikings raided across Europe, but took the most slaves in raids on the British Isles and in Eastern Europe. While the Vikings kept some slaves as servants, known as , they sold most captives in the Byzantine or Islamic markets. In the West, their target populations were primarily English, Irish, and Scottish, while in the East they were mainly Slavs. The Viking slave-trade slowly ended in the 11th century, as the Vikings settled in the European territories they had once raided. They converted serfs to Christianity and themselves merged with the local populace.

In central Europe, specifically the Frankish/German/Holy Roman Empire of Charlemagne, raids and wars to the east generated a steady supply of slaves from the Slavic captives of these regions. Because of high demand for slaves in the wealthy Muslim empires of Northern Africa, Spain, and the Near East, especially for slaves of European descent, a market for these slaves rapidly emerged. So lucrative was this market that it spawned an economic boom in central and western Europe, today known as the Carolingian Renaissance. This boom period for slaves stretched from the early Muslim conquests to the High Middle Ages but declined in the later Middle Ages as the Islamic Golden Age waned.

Medieval Spain and Portugal saw almost constant warfare between Muslims and Christians. Al-Andalus sent periodic raiding expeditions to loot the Iberian Christian kingdoms, bringing back booty and slaves. In a raid against Lisbon, Portugal in 1189, for example, the Almohad caliph Yaqub al-Mansur took 3,000 female and child captives. In a subsequent attack upon Silves, Portugal in 1191, his governor of Córdoba took 3,000 Christian slaves.

The Byzantine-Ottoman wars and the Ottoman wars in Europe resulted in the taking of large numbers of Christian slaves and using or selling them in the Islamic world too. After the battle of Lepanto the victors freed approximately 12,000 Christian galley slaves from the Ottoman fleet.

Similarly, Christians sold Muslim slaves captured in war. The Order of the Knights of Malta attacked pirates and Muslim shipping, and their base became a centre for slave trading, selling captured North Africans and Turks. Malta remained a slave market until well into the late 18th century. One thousand slaves were required to man the galleys (ships) of the Order.

Poland banned slavery in the 15th century; in Lithuania, slavery was formally abolished in 1588; the institution was replaced by the second enserfment. Slavery remained a minor institution in Russia until 1723, when Peter the Great converted the household slaves into house serfs. Russian agricultural slaves were formally converted into serfs earlier, in 1679. The escaped Russian serfs and kholops formed autonomous communities in the southern steppes, where they became known as Cossacks (meaning "outlaws").

Capture in war, voluntary servitude and debt slavery became common within the British Isles before 1066. Slaves were routinely bought and sold. Running away was also common and slavery was never a major economic factor in the British Isles during the Middle Ages. Ireland and Denmark provided markets for captured Anglo-Saxon and Celtic slaves. Pope Gregory I reputedly made the pun, Non Angli, sed Angeli ("Not Angles, but Angels"), after a response to his query regarding the identity of a group of fair-haired Angles, slave children whom he had observed in the marketplace. After the Norman Conquest, the law no longer supported chattel slavery and slaves became part of the larger body of serfs.

Barbary pirates and Maltese corsairs both raided for slaves and purchased slaves from European merchants, often the Radhanites, one of the few groups who could easily move between the Christian and Islamic worlds.

In the late Middle Ages, from 1100 to 1500, the European slave-trade continued, though with a shift from being centered among the Western Mediterranean Islamic nations to the Eastern Christian and Muslim states. The city-states of Venice and Genoa controlled the Eastern Mediterranean from the 12th century and the Black Sea from the 13th century. They sold both Slavic and Baltic slaves, as well as Georgians, Turks, and other ethnic groups of the Black Sea and Caucasus. The sale of European slaves by Europeans slowly ended as the Slavic and Baltic ethnic groups Christianized by the Late Middle Ages. European slaves did not pass on an inherited status and was thus more akin to forced labor, or indentured servitude.

From the 1440s into the 18th century, Europeans from Italy, Spain, Portugal, France, and England were sold into slavery by North Africans, as described in the book "Christian Slaves, Muslim Masters". This same book states that "white slavery had been minimised or ignored because academics preferred to treat Europeans as evil colonialists rather than as victims." and likely overestimates the number of slaves taken. In 1575, the Tatars captured over 35,000 Ukrainians; a 1676 raid took almost 40,000. About 60,000 Ukrainians were captured in 1688; some were ransomed, but most were sold into slavery. Some of the Roma people were enslaved over five centuries in Romania until abolition in 1864 (see Slavery in Romania).

The Mongol invasions and conquests in the 13th century also resulted in taking numerous captives into slavery. The Mongols enslaved skilled individuals, women and children and marched them to Karakorum or Sarai, whence they were sold throughout Eurasia. Many of these slaves were shipped to the slave market in Novgorod.

Slave commerce during the Late Middle Ages was mainly in the hands of Venetian and Genoese merchants and cartels, who were involved in the slave trade with the Golden Horde. In 1382 the Golden Horde under Khan Tokhtamysh sacked Moscow, burning the city and carrying off thousands of inhabitants as slaves. Between 1414 and 1423, some 10,000 eastern European slaves were sold in Venice. Genoese merchants organized the slave trade from the Crimea to Mamluk Egypt. For years, the Khanates of Kazan and Astrakhan routinely made raids on Russian principalities for slaves and to plunder towns. Russian chronicles record about 40 raids by Kazan Khans on the Russian territories in the first half of the 16th century.

In 1441 Haci I Giray declared independence from the Golden Horde and established the Crimean Khanate. For a long time, until the early 18th century, the khanate maintained an extensive slave-trade with the Ottoman Empire and the Middle East. In a process called the "harvesting of the steppe" they enslaved many Slavic peasants. About 30 major Tatar raids were recorded into Muscovite territories between 1558 and 1596.

Moscow was repeatedly a target. In 1521, the combined forces of Crimean Khan Mehmed Giray and his Kazan allies attacked the city and captured thousands of slaves. In 1571, the Crimean Tatars attacked and sacked Moscow, burning everything but the Kremlin and taking thousands of captives as slaves. In Crimea, about 75% of the population consisted of slaves.

In the Viking era beginning circa 793, the Norse raiders often captured and enslaved militarily weaker peoples they encountered. The Nordic countries called their slaves ( Old Norse: Þræll). The thralls were mostly from Western Europe, among them many Franks, Frisians, Anglo-Saxons, and both Irish and Britonnic Celts. Many Irish slaves travelled in expeditions for the colonization of Iceland. The Norse also took German, Baltic, Slavic and Latin slaves. The slave trade was one of the pillars of Norse commerce during the 6th through 11th centuries. The 10th-century Persian traveller Ibn Rustah described how Swedish Vikings, the Varangians or Rus, terrorized and enslaved the Slavs taken in their raids along the Volga River. The thrall system was finally abolished in the mid-14th century in Scandinavia.

Mediterranean powers frequently sentenced convicted criminals to row in the war- galleys of the state (initially only in time of war). After the revocation of the Edict of Nantes in 1685 and Camisard rebellion, the French Crown filled its galleys with French Huguenots, Protestants condemned for resisting the state. Galley-slaves lived and worked in such harsh conditions that many did not survive their terms of sentence, even if they survived shipwreck and slaughter or torture at the hands of enemies or of pirates. Naval forces often turned 'infidel' prisoners-of-war into galley-slaves. Several well-known historical figures served time as galley slaves after being captured by the enemy-the Ottoman corsair and admiral Turgut Reis and the Knights Hospitaller Grand Master Jean Parisot de la Valette among them.

Denmark-Norway was the first European country to ban the slave trade. This happened with a decree issued by King Christian VII of Denmark in 1792, to become fully effective by 1803. Slavery as an institution was not banned until 1848. At this time Iceland was a part of Denmark-Norway but slave trading had been abolished in Iceland in 1117 and had never been reestablished.

Slavery in the French Republic was abolished on 4 February 1794, including in its colonies. The lengthy Haitian Revolution by its slaves and free people of color established Haiti as a free republic in 1804 ruled by blacks, the first of its kind. At the time of the revolution, Haiti was known as Saint-Domingue and was a colony of France. Napoleon Bonaparte gave up on Haiti in 1803, but re-established slavery in Guadeloupe and Martinique in 1804, at the request of planters of the Caribbean colonies. Slavery was permanently abolished in the French empire during the French Revolution of 1848.

The 15th-century Portuguese exploration of the African coast is commonly regarded as the harbinger of European colonialism. In 1452, Pope Nicholas V issued the papal bull Dum Diversas, granting Afonso V of Portugal the right to reduce any "Saracens, pagans and any other unbelievers" to hereditary slavery which legitimized slave trade under Catholic beliefs of that time. This approval of slavery was reaffirmed and extended in his Romanus Pontifex bull of 1455. These papal bulls came to serve as a justification for the subsequent era of the slave trade and European colonialism. Although for a short period as in 1462, Pius II declared slavery to be "a great crime". The followers of the church of England and Protestants did not use the papal bull as a justification. The position of the church was to condemn the slavery of Christians, but slavery was regarded as an old established and necessary institution which supplied Europe with the necessary workforce. In the 16th century, African slaves had replaced almost all other ethnicities and religious enslaved groups in Europe. Within the Portuguese territory of Brazil, and even beyond its original borders, the enslavement of Native Americans was carried out by the Bandeirantes.

Among many other European slave markets, Genoa, and Venice were some well-known markets, their importance and demand growing after the great plague of the 14th century which decimated much of the European workforce. The maritime town of Lagos, Portugal, was the first slave market created in Portugal for the sale of imported African slaves, the Mercado de Escravos, which opened in 1444. In 1441, the first slaves were brought to Portugal from northern Mauritania. Prince Henry the Navigator, major sponsor of the Portuguese African expeditions, as of any other merchandise, taxed one fifth of the selling price of the slaves imported to Portugal. By the year 1552 African slaves made up 10 percent of the population of Lisbon. In the second half of the 16th century, the Crown gave up the monopoly on slave trade and the focus of European trade in African slaves shifted from import to Europe to slave transports directly to tropical colonies in the Americas-in the case of Portugal, especially Brazil. In the 15th century, one-third of the slaves were resold to the African market in exchange of gold. Slavery was abolished in mainland Portugal and Portuguese India in 1761. It was finally abolished in all Portuguese colonies in 1869.

The Spaniards were the first Europeans to use African slaves in the New World on islands such as Cuba and Hispaniola, due to a shortage of labor caused by the spread of diseases, and so the Spanish colonists gradually became involved in the Atlantic slave trade. The first African slaves arrived in Hispaniola in 1501; by 1517, the natives had been "virtually annihilated" mostly to diseases. The problem of the justness of Native American's slavery was a key issue for the Spanish Crown. It was Charles V who gave a definite answer to this complicated and delicate matter. To that end, on 25 November 1542, the Emperor abolished slavery by decree in his Leyes Nuevas New Laws. This bill was based on the arguments given by the best Spanish theologists and jurists who were unanimous in the condemnation of such slavery as unjust; they declared it illegitimate and outlawed it from America-not just the slavery of Spaniards over Natives-but also the type of slavery practiced among the Natives themselves Thus, Spain became the first country to officially abolish slavery.

However, in the Spanish colonies of Cuba and Puerto Rico, where sugarcane production was highly profitable based on slave labor, African slavery persisted until 1873 in Puerto Rico "with provisions for periods of apprenticeship", and 1886 in Cuba.

Although slavery was illegal inside the Netherlands it flourished throughout the Dutch Empire in the Americas, Africa, Ceylon and Indonesia. The Dutch Slave Coast ( Dutch: Slavenkust) referred to the trading posts of the Dutch West India Company on the Slave Coast, which lie in contemporary Ghana, Benin, Togo and Nigeria. Initially the Dutch shipped slaves to northern Brazil, and during the second half of the 17th century they had a controlling interest in the trade to the Spanish colonies. Today's Suriname and Guyana became prominent markets in the 18th century. Between 1612 and 1872, the Dutch operated from some 10 fortresses along the Gold Coast (now Ghana), from which slaves were shipped across the Atlantic. Dutch involvement on the Slave Coast increased with the establishment of a trading post in Offra in 1660. Willem Bosman writes in his Nauwkeurige beschrijving van de Guinese Goud- Tand- en Slavekust (1703) that Allada was also called Grand Ardra, being the larger cousin of Little Ardra, also known as Offra. From 1660 onward, Dutch presence in Allada and especially Offra became more permanent. A report from this year asserts Dutch trading posts, apart from Allada and Offra, in Benin City, Grand-Popo, and Savi.

The Offra trading post soon became the most important Dutch office on the Slave Coast. According to a 1670 report, annually 2,500 to 3,000 slaves were transported from Offra to the Americas. These numbers were only feasible in times of peace, however, and dwindled in time of conflict. From 1688 onward, the struggle between the Aja king of Allada and the peoples on the coastal regions, impeded the supply of slaves. The Dutch West India Company chose the side of the Aja king, causing the Offra office to be destroyed by opposing forces in 1692. By 1650 the Dutch had the pre-eminent slave trade in Europe and South East Asia. Later, trade shifted to Ouidah. On the instigation of Governor-General of the Dutch Gold Coast Willem de la Palma, Jacob van den Broucke was sent in 1703 as "opperkommies" (head merchant) to the Dutch trading post at Ouidah, which according to sources was established around 1670. Political unrest caused the Dutch to abandon their trading post at Ouidah in 1725, and they then moved to Jaquim, at which place they built Fort Zeelandia. The head of the post, Hendrik Hertog, had a reputation for being a successful slave trader. In an attempt to extend his trading area, Hertog negotiated with local tribes and mingled in local political struggles. He sided with the wrong party, however, leading to a conflict with Director-General Jan Pranger and to his exile to the island of Appa in 1732. The Dutch trading post on this island was extended as the new centre of the slave trade. In 1733, Hertog returned to Jaquim, this time extending the trading post into Fort Zeelandia. The revival of the slave trade at Jaquim was only temporary, however, as his superiors at the Dutch West India Company noticed that Hertog's slaves were more expensive than at the Gold Coast. From 1735, Elmina became the preferred spot to trade slaves. As of 1778, it was estimated that the Dutch were shipping approximately 6,000 Africans for enslavement in the Dutch West Indies each year. Slavery also characterised the Dutch possessions in Indonesia, Ceylon and South Africa, where Indonesians have made a significant contribution to the Cape Coloured population of that country. The Dutch part in the Atlantic slave trade is estimated at 5-7 percent, as they shipped about 550,000-600,000 African slaves across the Atlantic, about 75,000 of whom died on board before reaching their destinations. From 1596 to 1829, the Dutch traders sold 250,000 slaves in the Dutch Guianas, 142,000 in the Dutch Caribbean islands, and 28,000 in Dutch Brazil. In addition, tens of thousands of slaves, mostly from India and some from Africa, were carried to the Dutch East Indies. The Netherlands was one of the last countries to abolish slavery in 1863. Although the decision was made in 1848, it took many years for the law to be implemented. Furthermore, slaves in Suriname would be fully free only in 1873, since the law stipulated that there was to be a mandatory 10-year transition.

Barbary Corsairs continued to trade in European slaves into the Modern time-period. Muslim pirates, primarily Algerians with the support of the Ottoman Empire, raided European coasts and shipping from the 16th to the 19th centuries, and took thousands of captives, whom they sold or enslaved. Many were held for ransom, and European communities raised funds such as Malta's Monte della Redenzione degli Schiavi to buy back their citizens. The raids gradually ended with the naval decline of the Ottoman Empire in the late 16th and 17th centuries, as well as the European conquest of North Africa throughout the 19th century.

From 1609 to 1616, England lost 466 merchant ships to Barbary pirates. 160 English ships were captured by Algerians between 1677 and 1680. Many of the captured sailors were made into slaves and held for ransom. The corsairs were no strangers to the South West of England where raids were known in a number of coastal communities. In 1627 Barbary Pirates under command of the Dutch renegade Jan Janszoon (Murat Reis), operating from the Moroccan port of Salé, occupied the island of Lundy. During this time there were reports of captured slaves being sent to Algiers.

Ireland, despite its northern position, was not immune from attacks by the corsairs. In June 1631 Janszoon, with pirates from Algiers and armed troops of the Ottoman Empire, stormed ashore at the little harbor village of Baltimore, County Cork. They captured almost all the villagers and took them away to a life of slavery in North Africa. The prisoners were destined for a variety of fates-some lived out their days chained to the oars as galley slaves, while others would spend long years in the scented seclusion of the harem or within the walls of the sultan's palace. Only two of them ever saw Ireland again.

The Congress of Vienna (1814-15), which ended the Napoleonic Wars, led to increased European consensus on the need to end Barbary raiding. The sacking of Palma on the island of Sardinia by a Tunisian squadron, which carried off 158 inhabitants, roused widespread indignation. Britain had by this time banned the slave trade and was seeking to induce other countries to do likewise. States that were more vulnerable to the corsairs complained that Britain cared more for ending the trade in African slaves than stopping the enslavement of Europeans and Americans by the Barbary States.

In order to neutralise this objection and further the anti-slavery campaign, in 1816 Britain sent Lord Exmouth to secure new concessions from Tripoli, Tunis, and Algiers, including a pledge to treat Christian captives in any future conflict as prisoners of war rather than slaves. He imposed peace between Algiers and the kingdoms of Sardinia and Sicily. On his first visit, Lord Exmouth negotiated satisfactory treaties and sailed for home. While he was negotiating, a number of Sardinian fishermen who had settled at Bona on the Tunisian coast were brutally treated without his knowledge. As Sardinians they were technically under British protection, and the government sent Exmouth back to secure reparation. On 17 August, in combination with a Dutch squadron under Admiral Van de Capellen, Exmouth bombarded Algiers. Both Algiers and Tunis made fresh concessions as a result.

The Barbary states had difficulty securing uniform compliance with a total prohibition of slave-raiding, as this had been traditionally of central importance to the North African economy. Slavers continued to take captives by preying on less well-protected peoples. Algiers subsequently renewed its slave-raiding, though on a smaller scale. Europeans at the Congress of Aix-la-Chapelle in 1818 discussed possible retaliation. In 1820 a British fleet under Admiral Sir Harry Neal bombarded Algiers. Corsair activity based in Algiers did not entirely cease until France conquered the state in 1830.

The Crimeans frequently mounted raids into the Danubian principalities, Poland-Lithuania, and Muscovy to enslave people whom they could capture; for each captive, the khan received a fixed share (savğa) of 10% or 20%. These campaigns by Crimean forces were either sefers ("sojourns" - officially declared military operations led by the khans themselves), or çapuls ("despoiling" - raids undertaken by groups of noblemen, sometimes illegally because they contravened treaties concluded by the khans with neighbouring rulers).

For a long time, until the early 18th century, the Crimean Khanate maintained a massive slave trade with the Ottoman Empire and the Middle East, exporting about 2 million slaves from Russia and Poland-Lithuania over the period 1500-1700. Caffa (modern Feodosia) became one of the best-known and significant trading ports and slave markets. In 1769 the last major Tatar raid saw the capture of 20,000 Russian and Ruthenian slaves.

Author and historian Brian Glyn Williams writes:

Fisher estimates that in the sixteenth century the Polish-Lithuanian Commonwealth lost around 20,000 individuals a year and that from 1474 to 1694, as many as a million Commonwealth citizens were carried off into Crimean slavery.

Early modern sources are full of descriptions of sufferings of Christian slaves captured by the Crimean Tatars in the course of their raids:

It seems that the position and everyday conditions of a slave depended largely on his/her owner. Some slaves indeed could spend the rest of their days doing exhausting labor: as the Crimean vizir (minister) Sefer Gazi Aga mentions in one of his letters, the slaves were often "a plough and a scythe" of their owners. Most terrible, perhaps, was the fate of those who became galley-slaves, whose sufferings were poeticized in many Ukrainian dumas (songs). ... Both female and male slaves were often used for sexual purposes.

Britain played a prominent role in the Atlantic slave trade, especially after 1640, when sugar cane was introduced to the region. At first, most were white Britons, or Irish, enslaved as indentured labour - for a fixed period - in the West Indies. These people may have been criminals, political rebels, the poor with no prospects or others who were simply tricked or kidnapped. Slavery was a legal institution in all of the 13 American colonies and Canada (acquired by Britain in 1763). The profits of the slave trade and of West Indian plantations amounted to 5% of the British economy at the time of the Industrial Revolution.

A little-known incident in the career of Judge Jeffreys refers to an assize in Bristol in 1685 when he made the mayor of the city, then sitting fully robed beside him on the bench, go into the dock and be fined £1000 for being a 'kidnapping knave'; some Bristol traders at the time were known at the time to kidnap their own countrymen and ship them away as slaves.

Somersett's case in 1772 was generally taken at the time to have decided that the condition of slavery did not exist under English law in England. In 1785, English poet William Cowper wrote: "We have no slaves at home - Then why abroad? Slaves cannot breathe in England; if their lungs receive our air, that moment they are free. They touch our country, and their shackles fall. That's noble, and bespeaks a nation proud. And jealous of the blessing. Spread it then, And let it circulate through every vein." However, slavery continued to thrive in England itself, much like it did in the British Empire, until full emancipation in the 1830s. In 1807, following many years of lobbying by the abolitionist movement, led primarily by William Wilberforce, the British Parliament voted to make the slave trade illegal anywhere in the Empire with the Slave Trade Act 1807. Thereafter Britain took a prominent role in combating the trade, and slavery itself was abolished in the British Empire (except for India) with the Slavery Abolition Act 1833. Between 1808 and 1860, the West Africa Squadron seized approximately 1,600 slave ships and freed 150,000 Africans who were aboard. Action was also taken against African leaders who refused to agree to British treaties to outlaw the trade. Akitoye, the 11th Oba of Lagos, is famous for having used British involvement to regain his rule in return for suppressing slavery among the Yoruba people of Lagos in 1851. Anti-slavery treaties were signed with over 50 African rulers. In 1839, the world's oldest international human rights organization, Anti-Slavery International, was formed in Britain by Joseph Sturge, which worked to outlaw slavery in other countries.

After 1833, the freed African slaves declined employment in the cane fields. This led to the importation of indentured labour again - mainly from India, and also China.

In 1811, Arthur William Hodge was executed for the murder of a slave in the British West Indies. He was not, however, as some have claimed, the first white person to have been lawfully executed for the murder of a slave.

During World War II Nazi Germany operated several categories of Arbeitslager (Labor Camps) for different categories of inmates. The largest number of them held Polish and Jewish civilians forcibly abducted in the occupied countries (see Łapanka) to provide labor in the German war industry, repair bombed railroads and bridges or work on farms. By 1944, 20% of all workers were foreigners, either civilians or prisoners of war.

This is not classed as slavery per se, as defined in the first paragraph, i.e. slavery under this definition does not include other forced labour systems, such as historical forced labor by prisoners, labor camps, or other forms of unfree labor, in which labourers are not legally considered property. Slavery typically requires a shortage of labor and a surplus of land to be viable.

As agreed by the Allies at the Yalta conference Germans were used as forced labor as part of the reparations to be extracted. By 1947 it is estimated that 400,000 Germans (both civilians and POWs) were being used as forced labor by the U.S., France, the UK and the Soviet Union. German prisoners were for example forced to clear minefields in France and the Low Countries. By December 1945 it was estimated by French authorities that 2,000 German prisoners were being killed or injured each month in accidents. In Norway the last available casualty record, from 29 August 1945, shows that by that time a total of 275 German soldiers died while clearing mines, while 392 had been injured. Death rates for the German civilians doing forced labor in the Soviet Union ranged between 19% and 39%, depending on category.

In the first half of the 19th century, small-scale slave raids took place across Polynesia to supply labor and sex workers for the whaling and sealing trades, with examples from both the westerly and easterly extremes of the Polynesian triangle. By the 1860s this had grown to a larger scale operation with Peruvian slave raids in the South Sea Islands to collect labor for the guano industry.

Ancient Hawaii was a caste society. People were born into specific social classes. Kauwa were those of the outcast or slave class. They are believed to have been war captives, or the descendants of war captives. Marriage between higher castes and the kauwa was strictly forbidden. The kauwa worked for the chiefs and were often used as human sacrifices at the luakini heiau. (They were not the only sacrifices; law-breakers of all castes or defeated political opponents were also acceptable as victims.)

The kapu system was abolished during the ʻAi Noa in 1819, and with it the distinction between the kauwā slave class and the makaʻāinana (commoners). The 1852 Constitution of the Kingdom of Hawaii officially made slavery illegal.

Before the arrival of European settlers, each Maori tribe () considered itself a separate entity equivalent to a nation. In traditional Maori society of Aotearoa, prisoners of war became taurekareka, slaves, unless released, ransomed or eaten. With some exceptions, the child of a slave remained a slave.

As far as it is possible to tell, slavery seems to have increased in the early 19th century with increased numbers of prisoners being taken by Māori military leaders, such as Hongi Hika and Te Rauparaha to satisfy the need for labor in the Musket Wars, to supply whalers and traders with food, flax and timber in return for western goods. The intertribal Musket Wars lasted 1807 to 1843 when large numbers of slaves were captured by northern tribes who had acquired muskets. About 20,000 Maori died in the wars which were concentrated in the North Island. An unknown number of slaves were captured. Northern tribes used slaves (called mokai) to grow large areas of potatoes for trade with visiting ships. Chiefs started an extensive sex trade in the Bay of Islands in the 1830s using mainly slave girls. By 1835 about 70-80 ships per year called into the port. One French captain described the impossibility of getting rid of the girls who swarmed over his ship outnumbering his crew of 70 by 3 to 1. All payments to the girls were stolen by the chief. By 1833 Christianity had become established in the north and large numbers of slaves were freed. However two Taranaki tribes, Ngati Tama and Ngati Mutunga, displaced by the wars carried out a carefully planned invasion of the Chatham Islands, 800 km east of Christchurch, in 1835. About 15% of the Polynesian Moriori natives who had migrated to the islands at about 1500 CE were killed, with many women being tortured to death. The remaining population was enslaved for the purpose of growing food, especially potatoes. The Moriori were treated in an inhumane and degrading manner for many years. Their culture was banned and they were forbidden to marry. Slavery was outlawed when the British entered into a constitutional arrangement with New Zealand in 1840 via the Treaty of Waitangi, although it did not end completely until government was effectively extended over the whole of the country with the defeat of the Kingi movement in the Wars of the mid-1860s.

Some Maori took Moriori partners. The state of enslavement of Moriori lasted until the 1860s although it had been discouraged by CMS missionaries in North New Zealand from the late 1820s. In 1870 Ngati Mutunga, one of the invading tribes, argued before the Native Land Court in New Zealand that their gross mistreatment of the Moriori was standard Maori practice or tikanga.

One group of Polynesians who migrated to the Chatham Islands became the Moriori who developed a largely pacifist culture. It was originally speculated that they settled the Chathams direct from Polynesia, but it is now widely believed they were disaffected Maori who emigrated from the South Island of New Zealand. Their pacifism left the Moriori unable to defend themselves when the islands were invaded by mainland Māori in the 1830s. Two Taranaki tribes, Ngati Tama and Ngati Mutunga, displaced by the musket wars, carried out a carefully planned invasion of the Chatham Islands, 800 km east of Christchurch, in 1835. About 15% of the Polynesian Moriori natives who had migrated to the islands at about 1500 CE were killed, with many women being tortured to death. The remaining population was enslaved for the purpose of growing food, especially potatoes. The Moriori were treated in an inhumane and degrading manner for many years. Their culture was banned and they were forbidden to marry. Slavery was outlawed when the British annexed New Zealand in 1840, immediately prior to the signing of the Treaty of Waitangi, although it did not end completely until government was effectively extended over the whole of the country with the defeat of the Kingi movement in the Wars of the mid-1860s.

Some 300 Moriori men, women and children were massacred and the remaining 1,200 to 1,300 survivors were enslaved.

Rapa Nui / Easter Island

The isolated island of Rapa Nui/ Easter Island was inhabited by the Rapanui, who suffered a series of slave raids from 1805 or earlier, culminating in a near genocidal experience in the 1860s. The 1805 raid was by American sealers and was one of a series that changed the attitude of the islanders to outside visitors, with reports in the 1820s and 1830s that all visitors received a hostile reception. In December 1862, Peruvian slave raiders took between 1,400 and 2,000 islanders back to Peru to work in the guano industry; this was about a third of the island's population and included much of the island's leadership, the last ariki-mau and possibly the last who could read Rongorongo. After intervention by the French ambassador in Lima, the last 15 survivors were returned to the island, but brought with them smallpox, which further devastated the island.

Slavery has existed, in one form or another, throughout the whole of human history. So, too, have movements to free large or distinct groups of slaves. However, abolitionism should be distinguished from efforts to help a particular group of slaves, or to restrict one practice, such as the slave trade.

Although there were numerous slave revolts in the Caribbean, the only successful uprising came in the French colony of Haiti in the 1790s, where the slaves rose up, killed the mulattoes and whites, and established the independent Republic of Haiti. Europe recoiled in horror.

Cyrus the Great, the founder of Persian Empire prohibited the systematic enslavement of conquered non-combatant population. Cyrus also freed slaves and allowed all deported peoples who were enslaved by preceding Assyrian and Babylonian kings, to return home. It is said that he freed up to 40,000 Jews and allowed them to return home. Cylinder of Cyrus the Great containing the Decree on the conquered non-combatant population.

In 1772, the Somersett Case (R. v. Knowles, ex parte Somersett) of the English Court of King's Bench ruled that it was unlawful for a slave to be forcibly taken abroad. The case has since been misrepresented as finding that slavery was unlawful in England (although not elsewhere in the British Empire). A similar case, that of Joseph Knight, took place in Scotland five years later and ruled slavery to be contrary to the law of Scotland.

Following the work of campaigners in the United Kingdom, such as William Wilberforce and Thomas Clarkson, the Act for the Abolition of the Slave Trade was passed by Parliament on 25 March 1807, coming into effect the following year. The act imposed a fine of £100 for every slave found aboard a British ship. The intention was to outlaw entirely the Atlantic slave trade within the whole British Empire.

The significance of the abolition of the British slave trade lay in the number of people hitherto sold and carried by British slave vessels. Britain shipped 2,532,300 Africans across the Atlantic, equalling 41% of the total transport of 6,132,900 individuals. This made the British empire the biggest slave-trade contributor in the world due to the magnitude of the empire, which made the abolition act all the more damaging to the global trade of slaves. Britain used its diplomatic influence to press other nations into treaties to ban their slave trade and to give the Royal Navy the right to interdict slave ships sailing under their national flag.

The Slavery Abolition Act, passed on 1 August 1833, outlawed slavery itself throughout the British Empire, with the exception of India. On 1 August 1834 slaves became indentured to their former owners in an apprenticeship system for six years. Full emancipation was granted ahead of schedule on 1 August 1838. Britain abolished slavery in both Hindu and Muslim India with the Indian Slavery Act, 1843.

Domestic slavery practised by the educated African coastal elites (as well as interior traditional rulers) in Sierra Leone was abolished in 1928. A study found practices of domestic slavery still widespread in rural areas in the 1970s.

There were slaves in mainland France (especially in trade ports such as Nantes or Bordeaux)., but the institution was never officially authorized there. The legal case of Jean Boucaux in 1739 clarified the unclear legal position of possible slaves in France, and was followed by laws that established registers for slaves in mainland France, who were limited to a three-year stay, for visits or learning a trade. Unregistered "slaves" in France were regarded as free. However, slavery was of vital importance in France's Caribbean possessions, especially Saint-Domingue.

In 1793, influenced by the French Declaration of the Rights of Man of August 1789 and alarmed as the massive slave revolt of August 1791 that had become the Haitian Revolution threatened to ally itself with the British, the French Revolutionary commissioners Sonthonax and Polverel declared general emancipation to reconcile them with France. In Paris, on 4 February 1794, Abbé Grégoire and the Convention ratified this action by officially abolishing slavery in all French territories outside mainland France, freeing all the slaves both for moral and security reasons.

Napoleon came to power in 1799 and soon had grandiose plans for the French sugar colonies; to achieve them he reintroduced slavery. Napoleon's major adventure into the Caribbean-sending 30,000 troops in 1802 to retake Saint Domingue (Haiti) from ex-slaves under Toussaint L'Ouverture who had revolted. Napoleon wanted to preserve France's financial benefits from the colony's sugar and coffee crops; he then planned to establish a major base at New Orleans. He therefore re-established slavery in Haiti and Guadeloupe, where it had been abolished after rebellions. Slaves and black freedmen fought the French for their freedom and independence. Revolutionary ideals played a central role in the fighting for it was the slaves and their allies who were fighting for the revolutionary ideals of freedom and equality, while the French troops under General Charles Leclerc fought to restore the order of the ancien régime. The goal of re-establishing slavery explicitly contradicted the ideals of the French Revolution. The French soldiers were unable to cope with the tropical diseases, and most died of yellow fever. Slavery was reimposed in Guadeloupe but not in Haiti, which became an independent black republic. Napoleon's vast colonial dreams for Egypt, India, the Caribbean, Louisiana, and even Australia were all doomed for lack of a fleet capable of matching Britain's Royal Navy. Realizing the fiasco Napoleon liquidated the Haiti project, brought home the survivors and sold off the huge Louisiana territory to the US in 1803.

In 1794 slavery was abolished in the French Empire. After seizing Lower Egypt in 1798, Napoleon Bonaparte issued a proclamation in Arabic, declaring all men to be free and equal. However, the French bought males as soldiers and females as concubines. Napoleon personally opposed the abolition and restored colonial slavery in 1802, a year after the capitulation of his troops in Egypt.

Victor Schœlcher and the 1848 abolition

The American Colonization Society, the primary vehicle for returning black Americans to greater freedom in Africa, established the colony of Liberia in 1821-23, on the premise that former American slaves would have greater freedom and equality there. The ACS assisted in the movement of thousands of African Americans to Liberia, with its founder Henry Clay stating; "unconquerable prejudice resulting from their color, they never could amalgamate with the free whites of this country. It was desirable, therefore, as it respected them, and the residue of the population of the country, to drain them off". Abraham Lincoln, an enthusiastic supporter of Clay, adopted his position on returning the blacks to their own land.

Slaves in the United States who escaped ownership would often make their way to Canada via the " Underground Railroad". The more famous of the African American abolitionists include former slaves Harriet Tubman, Sojourner Truth and Frederick Douglass. Many more people who opposed slavery and worked for abolition were northern whites, such as William Lloyd Garrison and John Brown. Slavery was legally abolished in 1865 by the Thirteenth Amendment to the United States Constitution.

While abolitionists agreed on the evils of slavery, there were differing opinions on what should happen after African Americans were freed. By the time of Emancipation, African-Americans were now native to the United States and did not want to leave. Most believed that their labor had made the land theirs as well as that of the whites.

The Declaration of the Powers, on the Abolition of the Slave Trade, of 8 February 1815 (Which also formed ACT, No. XV. of the Final Act of the Congress of Vienna of the same year) included in its first sentence the concept of the "principles of humanity and universal morality" as justification for ending a trade that was "odious in its continuance".

The 1926 Slavery Convention, an initiative of the League of Nations, was a turning point in banning global slavery. Article 4 of the Universal Declaration of Human Rights, adopted in 1948 by the UN General Assembly, explicitly banned slavery. The United Nations 1956 Supplementary Convention on the Abolition of Slavery was convened to outlaw and ban slavery worldwide, including child slavery. In December 1966, the UN General Assembly adopted the International Covenant on Civil and Political Rights, which was developed from the Universal Declaration of Human Rights. Article 4 of this international treaty bans slavery. The treaty came into force in March 1976 after it had been ratified by 35 nations.

As of November 2003, 104 nations had ratified the treaty. However, illegal forced labour involves millions of people in the 21st century, 43% for sexual exploitation and 32% for economic exploitation.

In May 2004, the 22 members of the Arab League adopted the Arab Charter on Human Rights, which incorporated the 1990 Cairo Declaration on Human Rights in Islam, which states:

Human beings are born free, and no one has the right to enslave, humiliate, oppress or exploit them, and there can be no subjugation but to God the Most-High.

-  Article 11, Cairo Declaration on Human Rights in Islam, 1990

Currently, the Anti-trafficking Coordination Team Initiative (ACT Team Initiative), a coordinated effort between the U.S. departments of justice, homeland security and labor, addresses human trafficking. The International Labour Organization estimates that there are 20.9 million victims of human trafficking globally, including 5.5 million children, of which 55% are women and girls.

The history of slavery originally was the history of the government's laws and policies toward slavery, and the political debates about it. Black history was promoted very largely at black colleges. The situation changed dramatically with the coming of the Civil Rights Movement of the 1950s. Attention shifted to the enslaved humans, the free blacks, and the struggles of the black community against adversity.

Peter Kolchin described the state of historiography in the early 20th century as follows:

During the first half of the twentieth century, a major component of this approach was often simply racism, manifest in the belief that blacks were, at best, imitative of whites. Thus Ulrich B. Phillips, the era's most celebrated and influential expert on slavery, combined a sophisticated portrait of the white planters' life and behavior with crude passing generalizations about the life and behavior of their black slaves.

Historians James Oliver Horton and Lois E. Horton described Phillips' mindset, methodology and influence:

His portrayal of blacks as passive, inferior people, whose African origins made them uncivilized, seemed to provide historical evidence for the theories of racial inferiority that supported racial segregation. Drawing evidence exclusively from plantation records, letters, southern newspapers, and other sources reflecting the slaveholder's point of view, Phillips depicted slave masters who provided for the welfare of their slaves and contended that true affection existed between master and slave.

Their account of the era rested, as one member of the Dunning school put it, on the assumption of "negro incapacity." Finding it impossible to believe that blacks could ever be independent actors on the stage of history, with their own aspirations and motivations, Dunning et al. portrayed African Americans either as "children", ignorant dupes manipulated by unscrupulous whites, or as savages, their primal passions unleashed by the end of slavery.

In the portrayal of the slave as a victim, the historian Stanley M. Elkins in his 1959 work Slavery: A Problem in American Institutional and Intellectual Life compared the effects of United States slavery to that resulting from the brutality of the Nazi concentration camps. He stated the institution destroyed the will of the slave, creating an "emasculated, docile Sambo" who identified totally with the owner. Elkins' thesis was challenged by historians. Gradually historians recognized that in addition to the effects of the owner-slave relationship, slaves did not live in a "totally closed environment but rather in one that permitted the emergence of enormous variety and allowed slaves to pursue important relationships with persons other than their master, including those to be found in their families, churches and communities."

Economic historians Robert W. Fogel and Stanley L. Engerman in the 1970s, through their work Time on the Cross, portrayed slaves as having internalized the Protestant work ethic of their owners. In portraying the more benign version of slavery, they also argue in their 1974 book that the material conditions under which the slaves lived and worked compared favorably to those of free workers in the agriculture and industry of the time. (This was also an argument of Southerners during the 19th century.)

In the 1970s and 1980s, historians made use of sources such as black music and statistical census data to create a more detailed and nuanced picture of slave life. Relying also on 19th-century autobiographies of ex-slaves (known as slave narratives) and the WPA Slave Narrative Collection, a set of interviews conducted with former slaves in the 1930s by the Federal Writers' Project, historians described slavery as the slaves remembered it. Far from slaves' being strictly victims or content, historians showed slaves as both resilient and autonomous in many of their activities. Despite their exercise of autonomy and their efforts to make a life within slavery, current historians recognize the precariousness of the slave's situation. Slave children quickly learned that they were subject to the direction of both their parents and their owners. They saw their parents disciplined just as they came to realize that they also could be physically or verbally abused by their owners. Historians writing during this era include John Blassingame ( Slave Community), Eugene Genovese ( Roll, Jordan, Roll), Leslie Howard Owens ( This Species of Property), and Herbert Gutman ( The Black Family in Slavery and Freedom).

Important work on slavery has continued; for instance, in 2003 Steven Hahn published the Pulitzer Prize-winning account, A Nation under Our Feet: Black Political Struggles in the Rural South from Slavery to the Great Migration, which examined how slaves built community and political understanding while enslaved, so they quickly began to form new associations and institutions when emancipated, including black churches separate from white control. In 2010, Robert E. Wright published a model that explains why slavery was more prevalent in some areas than others (e.g. southern than northern Delaware) and why some firms (individuals, corporations, plantation owners) chose slave labor while others used wage, indentured, or family labor instead.

Historical revisionism arrived when West Indian historian Eric Williams, a Marxist, in Capitalism and Slavery (1944), rejected this moral explanation and argued that abolition was now more profitable, for a century of sugarcane raising had exhausted the soil of the islands, and the plantations had become unprofitable. It was more profitable to sell the slaves to the government than to keep up operations. The 1807 prohibition of the international trade, Williams argued, prevented French expansion on other islands. Meanwhile, British investors turned to Asia, where labor was so plentiful that slavery was unnecessary. Williams went on to argue that slavery played a major role in making Britain prosperous. The high profits from the slave trade, he said, helped finance the Industrial Revolution. Britain enjoyed prosperity because of the capital gained from the unpaid work of slaves.

Since the 1970s numerous historians have challenged Williams from various angles and Gad Heuman has concluded, "More recent research has rejected this conclusion; it is now clear that the colonies of the British Caribbean profited considerably during the Revolutionary and Napoleonic Wars." In his major attack on the Williams's thesis, Seymour Drescher argues that Britain's abolition of the slave trade in 1807 resulted not from the diminishing value of slavery for Britain but instead from the moral outrage of the British voting public. Critics have also argued that slavery remained profitable in the 1830s because of innovations in agriculture so the profit motive was not central to abolition. Richardson (1998) finds Williams's claims regarding the Industrial Revolution are exaggerated, for profits from the slave trade amounted to less than 1% of domestic investment in Britain. Richardson further challenges claims (by African scholars) that the slave trade caused widespread depopulation and economic distress in Africa-indeed that it caused the "underdevelopment" of Africa. Admitting the horrible suffering of slaves, he notes that many Africans benefited directly because the first stage of the trade was always firmly in the hands of Africans. European slave ships waited at ports to purchase cargoes of people who were captured in the hinterland by African dealers and tribal leaders. Richardson finds that the "terms of trade" (how much the ship owners paid for the slave cargo) moved heavily in favor of the Africans after about 1750. That is, indigenous elites inside West and Central Africa made large and growing profits from slavery, thus increasing their wealth and power.

Economic historian Stanley Engerman finds that even without subtracting the associated costs of the slave trade (e.g., shipping costs, slave mortality, mortality of British people in Africa, defense costs) or reinvestment of profits back into the slave trade, the total profits from the slave trade and of West Indian plantations amounted to less than 5% of the British economy during any year of the Industrial Revolution. Engerman's 5% figure gives as much as possible in terms of benefit of the doubt to the Williams argument, not solely because it does not take into account the associated costs of the slave trade to Britain, but also because it carries the full-employment assumption from economics and holds the gross value of slave trade profits as a direct contribution to Britain's national income. Historian Richard Pares, in an article written before Williams's book, dismisses the influence of wealth generated from the West Indian plantations upon the financing of the Industrial Revolution, stating that whatever substantial flow of investment from West Indian profits into industry there was occurred after emancipation, not before.

The history of slavery spans many cultures, nationalities, and religions from ancient times to the present day. However the social, economic, and legal positions of slaves have differed vastly in different systems of slavery in different times and places.

Slavery occurs relatively rarely among hunter-gatherer populations because it develops under conditions of social stratification. Slavery operated in the very first civilizations (such as Sumer in Mesopotamia, which dates back as far as 3500 BCE). Slavery features in the Mesopotamian Code of Hammurabi (c. 1860 BCE), which refers to it as an established institution. Slavery became common within much of Europe during the Early Middle Ages and it continued into the following centuries. The Byzantine-Ottoman wars (1265-1479) and the Ottoman wars in Europe (14th to 20th centuries) resulted in the capture of large numbers of Christian slaves. The Dutch, French, Spanish, Portuguese, British, Arabs and a number of West African kingdoms played a prominent role in the Atlantic slave trade, especially after 1600. The Republic of Ragusa became the first European country to ban the slave trade in 1416. In modern times Denmark-Norway abolished the trade in 1802.

Although slavery is no longer legal anywhere in the world (with the exception of penal labour), human trafficking remains an international problem and an estimated 25-40 million people were enslaved as of 2013, the majority in Asia. During the 1983-2005 Second Sudanese Civil War people were taken into slavery. Evidence emerged in the late 1990s of systematic child-slavery and -trafficking on cacao plantations in West Africa. Slavery continues into the 21st century. Although Mauritania criminalized slavery in August 2007, an estimated up to 600,000 men, women and children, or 20% of the population of Mauritania, are currently enslaved, many of them used as bonded labor. Slavery in the 21st century continues, with the top ten countries with the highest prevalence according to the Global Slavery Index being North Korea, Eritrea, Burundi, the Central African Republic, Afghanistan, Mauritania, South Sudan, Pakistan, Cambodia and Iran. Islamist quasi-states such as the Islamic State of Iraq and the Levant and Boko Haram have abducted and enslaved women and children (often to serve as sex slaves).

Evidence of slavery predates written records, and has existed in many cultures. Mass slavery requires economic surpluses and a high population density to be viable. Due to these factors, the practice of slavery would have only proliferated after the invention of agriculture during the Neolithic Revolution, about 11,000 years ago.

C. 1480 BCE, fugitive slave treaty between Idrimi of Alakakh (now Tell Atchana) and Pillia of Kizzuwatna (now Cilicia).

French historian Fernand Braudel noted that slavery was endemic in Africa and part of the structure of everyday life. "Slavery came in different guises in different societies: there were court slaves, slaves incorporated into princely armies, domestic and household slaves, slaves working on the land, in industry, as couriers and intermediaries, even as traders". During the 16th century, Europe began to outpace the Arab world in the export traffic, with its slave traffic from Africa to the Americas. The Dutch imported slaves from Asia into their colony in South Africa. In 1807 Britain, which held extensive, although mainly coastal, colonial territories on the African continent (including southern Africa), made the international slave trade illegal, as did the United States in 1808.

Slavery in Ethiopia persisted until 1942. The Anti-Slavery Society estimated that there were 2,000,000 slaves in the early 1930s, out of an estimated population of between 8 and 16 million. It was finally abolished by order of emperor Haile Selassie on 26 August 1942.

When British rule was first imposed on the Sokoto Caliphate and the surrounding areas in northern Nigeria at the turn of the 20th century, approximately 2 million to 2.5 million people there were slaves. Slavery in northern Nigeria was finally outlawed in 1936.

Elikia M'bokolo, April 1998, Le Monde diplomatique. Quote: "The African continent was bled of its human resources via all possible routes. Across the Sahara, through the Red Sea, from the Indian Ocean ports and across the Atlantic. At least ten centuries of slavery for the benefit of the Muslim countries (from the ninth to the nineteenth)." He continues: "Four million slaves exported via the Red Sea, another four million through the Swahili ports of the Indian Ocean, perhaps as many as nine million along the trans-Saharan caravan route, and eleven to twenty million (depending on the author) across the Atlantic Ocean"

Zanzibar was once East Africa's main slave-trading port, and under Omani Arabs in the 19th century, as many as 50,000 slaves were passing through the city each year.

Prior to the 16th century, the bulk of slaves exported from Africa were shipped from East Africa to the Arabian peninsula. Zanzibar became a leading port in this trade. Arab slave traders differed from European ones in that they would often conduct raiding expeditions themselves, sometimes penetrating deep into the continent. They also differed in that their market greatly preferred the purchase of female slaves over male ones.

The increased presence of European rivals along the East coast led Arab traders to concentrate on the overland slave caravan routes across the Sahara from the Sahel to North Africa. The German explorer Gustav Nachtigal reported seeing slave caravans departing from Kukawa in Bornu bound for Tripoli and Egypt in 1870. The slave trade represented the major source of revenue for the state of Bornu as late as 1898. The eastern regions of the Central African Republic have never recovered demographically from the impact of 19th-century raids from the Sudan and still have a population density of less than 1 person/km². During the 1870s, European initiatives against the slave trade caused an economic crisis in northern Sudan, precipitating the rise of Mahdist forces. Mahdi's victory created an Islamic state, one that quickly reinstituted slavery.

The Middle Passage, the crossing of the Atlantic to the Americas, endured by slaves laid out in rows in the holds of ships, was only one element of the well-known triangular trade engaged in by Portuguese, Dutch, Danish-Norwegians, French, British and others. Ships having landed slaves in Caribbean ports would take on sugar, indigo, raw cotton, and later coffee, and make for Liverpool, Nantes, Lisbon or Amsterdam. Ships leaving European ports for West Africa would carry printed cotton textiles, some originally from India, copper utensils and bangles, pewter plates and pots, iron bars more valued than gold, hats, trinkets, gunpowder and firearms and alcohol. Tropical shipworms were eliminated in the cold Atlantic waters, and at each unloading, a profit was made.

While talking about the slave trade in East Africa in his journals, "To overdraw its evil is a simple impossibility."

To overdraw its evil is a simple impossibility.

David Livingstone while travelling in the African Great Lakes Region in 1866 described a trail of slaves as such:

19th June 1866 - We passed a woman tied by the neck to a tree and dead, the people of the country explained that she had been unable to keep up with the other slaves in a gang, and her master had determined that she should not become anyone's property if she recovered.
26th June. - ...We passed a slave woman shot or stabbed through the body and lying on the path: a group of men stood about a hundred yards off on one side, and another of the women on the other side, looking on; they said an Arab who passed early that morning had done it in anger at losing the price he had given for her, because she was unable to walk any longer.
27th June 1866 - To-day we came upon a man dead from starvation, as he was very thin. One of our men wandered and found many slaves with slave-sticks on, abandoned by their masters from want of food; they were too weak to be able to speak or say where they had come from; some were quite young.

The strangest disease I have seen in this country seems really to be broken-heartedness, and it attacks free men who have been captured and made slaves... Twenty one were unchained, as now safe; however all ran away at once; but eight with many others still in chains, died in three days after the crossing. They described their only pain in the heart, and placed the hand correctly on the spot, though many think the organ stands high up in the breast-bone.

African states played a role in the slave trade, and slavery was a common practice among Sub Saharan Africans before the involvement of the Arabs, Berbers and Europeans. There were three types: those who were slaves through conquest, those who were slaves due to unpaid debts, or those whose parents gave them as slaves to tribal chiefs. Chieftains would barter their slaves to Arab, Berber, Ottoman or European buyers for rum, spices, cloth or other goods. Selling captives or prisoners was commonly practiced among Africans, Turks, Berbers and Arabs during that era. However, as the Atlantic slave trade increased its demand, local systems which primarily serviced indentured servitude expanded. European slave trading, as a result, was the most pivotal change in the social, economic, cultural, spiritual, religious, political dynamics of the concept of slave trading. It ultimately undermined local economies and political stability as villages' vital labour forces were shipped overseas as slave raids and civil wars became commonplace. Crimes which were previously punishable by some other means became punishable by enslavement.

The kings of Dahomey sold their war captives into transatlantic slavery, who otherwise may have been killed in a ceremony known as the Annual Customs. As one of West Africa's principal slave states, Dahomey became extremely unpopular with neighbouring peoples. Like the Bambara Empire to the east, the Khasso kingdoms depended heavily on the slave trade for their economy. A family's status was indicated by the number of slaves it owned, leading to wars for the sole purpose of taking more captives. This trade led the Khasso into increasing contact with the European settlements of Africa's west coast, particularly the French. Benin grew increasingly rich during the 16th and 17th centuries on the slave trade with Europe; slaves from enemy states of the interior were sold, and carried to the Americas in Dutch and Portuguese ships. The Bight of Benin's shore soon came to be known as the "Slave Coast".

The slave trade is the ruling principle of my people. It is the source and the glory of their wealth...the mother lulls the child to sleep with notes of triumph over an enemy reduced to slavery...

In 1807, under internal and external pressures, the United Kingdom made illegal the international trade in slaves. The Royal Navy was deployed to prevent slavers from the United States, France, Spain, Portugal, Holland, West Africa and Arabia. The King of Bonny (now in Nigeria) allegedly became dissatisfied of the British intervention in stopping slave trading.

We think this trade must go on. That is the verdict of our oracle and the priests. They say that your country, however great, can never stop a trade ordained by God himself.

Joseph Miller states that African buyers would prefer males, but in reality, women and children would be more easily captured as men fled. Those captured would be sold for various reasons such as food, debts, or servitude. Once captured, the journey to the coast killed many and weakened others. Disease engulfed many, and insufficient food damaged those who made it to the coasts. Scurvy was so common that it was known as mal de Luanda (Luanda sickness). The assumption for those who died on the journey died from malnutrition. As food was limited, water may have been just as bad. Dysentery was widespread and poor sanitary conditions at ports did not help. Since supplies were poor, slaves were not equipped with the best clothing that further exposed to more diseases.

If the fear of disease caused terror, the psyche of slaves for being captured was just as terrifying. The most popular assumption for being captured was Europeans were cannibals. Stories and rumours spread that whites captured Africans to eat them. Olaudah Equiano accounts his experience about the sorrow slaves encountered at the ports. He talks about his first moment on a slave ship and asked if he was going to be eaten. Yet, the worst for slaves has only begun, and the journey on the water proved to be more terrifying. For every 100 Africans captured, only 64 would reach the coast, and only about 50 would reach the New World.

Others believe that slavers had a vested interest in capturing rather than killing, and in keeping their captives alive; and that this coupled with the disproportionate removal of males and the introduction of new crops from the Americas ( cassava, maize) would have limited general population decline to particular regions of western Africa around 1760-1810, and in Mozambique and neighbouring areas half a century later. There has also been speculation that within Africa, females were most often captured as brides, with their male protectors being a "bycatch" who would have been killed if there had not been an export market for them.

British explorer Mungo Park encountered a group of slaves when traveling through Mandinka country:

They were all very inquisitive, but they viewed me at first with looks of horror, and repeatedly asked if my countrymen were cannibals. They were very desirous to know what became of the slaves after they had crossed the salt water. I told them that they were employed in cultivation the land; but they would not believe me ... A deeply-rooted idea that the whites purchase negroes for the purpose of devouring them, or of selling them to others that they may be devoured hereafter, naturally makes the slaves contemplate a journey towards the coast with great terror, insomuch that the slatees are forced to keep them constantly in irons, and watch them very closely, to prevent their escape.

During the period from the late 19th century and early 20th century, demand for the labour-intensive harvesting of rubber drove frontier expansion and forced labour. The personal monarchy of Belgian King Leopold II in the Congo Free State saw mass killings and slavery to extract rubber.

Stephanie Smallwood in her book Saltwater Slavery uses Equiano's account on board ships to describe the general thoughts of most slaves.

Then," said I, "how comes it in all our country we never heard of them?" They told me because they lived so very far off. I then asked where were their women? Had they any like themselves? I was told that they had. "And why," said I, "do we not see them?" They answered, because they were left behind. I asked how the vessel could go? They told me they could not tell; but that there was cloth put upon the masts by the help of the ropes I saw, and then the vessel went on; and the white men had some spell or magic they put in the water when they liked, in order to stop the vessel. I was exceedingly amazed at this account, and really thought they were spirits. I there-fore wished much to be from amongst them, for I expected they would sacrifice me; but my wishes were vain-for we were so quartered that it was impossible for any of us to make our escape.

Accounts like these raised many questions as some slaves grew philosophical with their journey. Smallwood points out the challenges for slaves were physical and metaphysical. The physical would be obvious as the challenge to overcome capacity, lack of ship room, and food. The metaphysical was unique as the open sea would challenge African slaves' vision of the ocean as habitable. At essence, the journey on the ocean would prove to be an African's biggest fear that would keep them in awe. Combining this with the lack of knowledge of the sea, Africans would be entering a world of anxiety never seen before. Yet, Europeans were also fearful of the sea, but not to the extent of Africans. One of these dilemmas came with the sense of time. Africans used seasonal weather to predict time and days. The moon was a sense of time, but used like in other cultures. On the sea, Africans used the moon to best count the days, but the sea did not provide seasonal changes for them to know how long they were at sea. Counting the days on a ship was not the main priority, however. Surviving the voyage was the main horror. No one escaped diseases as the close quarters infected everyone including the crew. Death was so common that ships were called tumbeiros or floating tombs. What shocked Africans the most was how death was handled in the ships. Smallwood says the traditions for an African death was delicate and community-based. On ships, bodies would be thrown into the sea. Because the sea represented bad omens, bodies in the sea represented a form of purgatory and the ship a form of hell. In the end, the Africans who made the journey would have survived disease, malnutrition, confined space, close death, and the trauma of the ship.

In Algiers during the time of the Regency of Algiers in North Africa in the 19th century, 1.5 million Christians and Europeans were captured and forced into slavery. This eventually led to the Bombardment of Algiers in 1816 by the British and Dutch, forcing the Dey of Algiers to free many slaves.

The trading of children has been reported in modern Nigeria and Benin. In parts of Ghana, a family may be punished for an offense by having to turn over a virgin female to serve as a sex slave within the offended family. In this instance, the woman does not gain the title or status of "wife". In parts of Ghana, Togo, and Benin, shrine slavery persists, despite being illegal in Ghana since 1998. In this system of ritual servitude, sometimes called trokosi (in Ghana) or voodoosi in Togo and Benin, young virgin girls are given as slaves to traditional shrines and are used sexually by the priests in addition to providing free labor for the shrine.

An article in the Middle East Quarterly in 1999 reported that slavery is endemic in Sudan. Estimates of abductions during the Second Sudanese Civil War range from 14,000 to 200,000 people.

During the Second Sudanese Civil War people were taken into slavery; estimates of abductions range from 14,000 to 200,000. Abduction of Dinka women and children was common. In Mauritania it is estimated that up to 600,000 men, women and children, or 20% of the population, are currently enslaved, many of them used as bonded labor. Slavery in Mauritania was criminalized in August 2007.

During the Darfur conflict that began in 2003, many people were kidnapped by Janjaweed and sold into slavery as agricultural labor, domestic servants and sex slaves.

In Niger, slavery is also a current phenomenon. A Nigerien study has found that more than 800,000 people are enslaved, almost 8% of the population. Niger installed an anti-slavery provision in 2003. In a landmark ruling in 2008, the ECOWAS Community Court of Justice declared that the Republic of Niger failed to protect Hadijatou Mani Koraou from slavery, and awarded Mani CFA 10,000,000 (approximately US$20,000) in reparations.

Sexual slavery and forced labor are common in the Democratic Republic of Congo.

Many pygmies in the Republic of Congo and Democratic Republic of Congo belong from birth to Bantus in a system of slavery.

Evidence emerged in the late 1990s of systematic slavery in cacao plantations in West Africa; see the chocolate and slavery article.

On the night of 14-15 April 2014, a group of militants attacked the Government Girls Secondary School in Chibok, Nigeria. They broke into the school, pretending to be guards, telling the girls to get out and come with them. A large number of students were taken away in trucks, possibly into the Konduga area of the Sambisa Forest where Boko Haram were known to have fortified camps. Houses in Chibok were also burned down in the incident. According to police, approximately 276 children were taken in the attack, of whom 53 had escaped as of 2 May. Other reports said that 329 girls were kidnapped, 53 had escaped and 276 were still missing. The students have been forced to convert to Islam and into marriage with members of Boko Haram, with a reputed " bride price" of ₦2,000 each ($12.50/ £7.50). Many of the students were taken to the neighbouring countries of Chad and Cameroon, with sightings reported of the students crossing borders with the militants, and sightings of the students by villagers living in the Sambisa Forest, which is considered a refuge for Boko Haram.

On 5 May 2014 a video in which Boko Haram leader Abubakar Shekau claimed responsibility for the kidnappings emerged. Shekau claimed that "Allah instructed me to sell them...I will carry out his instructions" and "[s]lavery is allowed in my religion, and I shall capture people and make them slaves." He said the girls should not have been in school and instead should have been married since girls as young as nine are suitable for marriage.

During the Second Libyan Civil War Libyans started capturing some of the Sub-Saharan African migrants trying to get to Europe through Libya and selling them on slave markets. Slaves are often ransomed to their families and in the meantime until ransom can be paid, they may be tortured, forced to work, sometimes worked to death, and eventually they may be executed or left to starve if the payment has not been made after a period of time. Women are often raped and used as sex slaves and sold to brothels.

Many child migrants also suffer from abuse and child rape in Libya.

In Pre-Columbian Mesoamerica the most common forms of slavery were those of prisoners of war and debtors. People unable to pay back debts could be sentenced to work as slaves to the persons owed until the debts were worked off. Warfare was important to Maya society, because raids on surrounding areas provided the victims required for human sacrifice, as well as slaves for the construction of temples. Most victims of human sacrifice were prisoners of war or slaves. Slavery was not usually hereditary; children of slaves were born free. In the Inca Empire, workers were subject to a in lieu of taxes which they paid by working for the government. Each , or extended family, would decide which family member to send to do the work. It is unclear if this labor draft or corvée counts as slavery. The Spanish adopted this system, particularly for their silver mines in Bolivia.

Other slave-owning societies and tribes of the New World were, for example, the Tehuelche of Patagonia, the Comanche of Texas, the Caribs of Dominica, the Tupinambá of Brazil, the fishing societies, such as the Yurok, that lived along the coast from what is now Alaska to California, the Pawnee and Klamath. Many of the indigenous peoples of the Pacific Northwest Coast, such as the Haida and Tlingit, were traditionally known as fierce warriors and slave-traders, raiding as far as California. Slavery was hereditary, the slaves being prisoners of war. Among some Pacific Northwest tribes about a quarter of the population were slaves. One slave narrative was composed by an Englishman, John R. Jewitt, who had been taken alive when his ship was captured in 1802; his memoir provides a detailed look at life as a slave, and asserts that a large number were held.

During the period from the late 19th century and early 20th century, demand for the labor-intensive harvesting of rubber drove frontier expansion and slavery in Latin America and elsewhere. Indigenous peoples were enslaved as part of the rubber boom in Ecuador, Peru, Colombia, and Brazil. In Central America, rubber tappers participated in the enslavement of the indigenous Guatuso-Maleku people for domestic service.

Slavery was a mainstay of the Brazilian colonial economy, especially in mining and sugarcane production. 35.3% of all slaves involved in the Atlantic Slave trade went to Brazil. 4 million slaves were obtained by Brazil, 1.5 million more than any other country. Starting around 1550, the Portuguese began to trade African slaves to work the sugar plantations, once the native Tupi people deteriorated. Although Portuguese Prime Minister Sebastião José de Carvalho e Melo, 1st Marquis of Pombal abolished slavery in mainland Portugal on 12 February 1761, slavery continued in her overseas colonies. Slavery was practiced among all classes. Slaves were owned by upper and middle classes, by the poor, and even by other slaves.

From São Paulo, the Bandeirantes, adventurers mostly of mixed Portuguese and native ancestry, penetrated steadily westward in their search for Indian slaves. Along the Amazon river and its major tributaries, repeated slaving raids and punitive attacks left their mark. One French traveler in the 1740s described hundreds of miles of river banks with no sign of human life and once-thriving villages that were devastated and empty. In some areas of the Amazon Basin, and particularly among the Guarani of southern Brazil and Paraguay, the Jesuits had organized their Jesuit Reductions along military lines to fight the slavers. In the mid-to-late 19th century, many Amerindians were enslaved to work on rubber plantations.

Escaped slaves formed Maroon communities which played an important role in the histories of Brazil and other countries such as Suriname, Puerto Rico, Cuba, and Jamaica. In Brazil, the Maroon villages were called palenques or quilombos. Maroons survived by growing vegetables and hunting. They also raided plantations. At these attacks, the maroons would burn crops, steal livestock and tools, kill slavemasters, and invite other slaves to join their communities.

Jean-Baptiste Debret, a French painter who was active in Brazil in the first decades of the 19th century, started out with painting portraits of members of the Brazilian Imperial family, but soon became concerned with the slavery of both blacks and indigenous inhabitants. His paintings on the subject (two appear on this page) helped bring attention to the subject in both Europe and Brazil itself.

The Clapham Sect, a group of evangelical reformers, campaigned during much of the 19th century for Britain to use its influence and power to stop the traffic of slaves to Brazil. Besides moral qualms, the low cost of slave-produced Brazilian sugar meant that British colonies in the West Indies were unable to match the market prices of Brazilian sugar, and each Briton was consuming 16 pounds (7 kg) of sugar a year by the 19th century. This combination led to intensive pressure from the British government for Brazil to end this practice, which it did by steps over several decades.

Brazil's 1877-78 Grande Seca (Great Drought) in the cotton-growing northeast led to major turmoil, starvation, poverty and internal migration. As wealthy plantation holders rushed to sell their slaves south, popular resistance and resentment grew, inspiring numerous emancipation societies. They succeeded in banning slavery altogether in the province of Ceará by 1884. Slavery was legally ended nationwide on 13 May by the ("Golden Law") of 1888. It was an institution in decadence at these times, as since the 1880s the country had begun to use European immigrant labor instead. Brazil was the last nation in the Western Hemisphere to abolish slavery.

Slavery was commonly used in the parts of the Caribbean controlled by France and the British Empire. The Lesser Antilles islands of Barbados, St. Kitts, Antigua, Martinique and Guadeloupe, which were the first important slave societies of the Caribbean, began the widespread use of African slaves by the end of the 17th century, as their economies converted from sugar production.

England had multiple sugar islands in the Caribbean, especially Jamaica, Barbados, Nevis, and Antigua, which provided a steady flow of sugar sales; slave labor produced the sugar. By the 1700s, there were more slaves in Barbados than all the colonies combined. Since Barbados did not have many mountains, the British were able to clear land for sugar cane. Indentured servants were initially sent to Barbados to work in the sugar fields. These indentured servants were treated so poorly that future indentured servants stopped going to Barbados, and there were not enough people to work the fields. This is when the British started bringing in African slaves. It was important for the slaves to be in Barbados because sugar had become a necessity for most people and the demand for it was high.

An important result of Britain's victory in the War of the Spanish Succession (1702-1714) was enlarging its role in the slave trade. Of special importance was the successful secret negotiation with France to obtain thirty-year monopoly on the Spanish slave trade, called the Queen Anne of Great Britain also allowed her North American colonies like Virginia to make laws that promoted black slavery. Anne had secretly negotiated with France to get its approval regarding the Asiento. She boasted to Parliament of her success in taking the Asiento away from France and London celebrated her economic coup. Most of the slave trade involved sales to Spanish colonies in the Caribbean, and to Mexico, as well as sales to British colonies in the Caribbean and in North America. Historian Vinita Ricks says the agreement allotted Queen Anne "22.5% (and King Philip V, of Spain 28%) of all profits collected for her personal fortune." Ricks concludes that the Queen's "connection to slave trade revenue meant that she was no longer a neutral observer. She had a vested interest in what happened on slave ships."

By 1778, the French were importing approximately 13,000 Africans for enslavement yearly to the French West Indies.

To regularise slavery, in 1685 Louis XIV had enacted the , which accorded certain human rights to slaves and responsibilities to the master, who was obliged to feed, clothe and provide for the general well-being of his slaves. Free blacks owned one-third of the plantation property and one-quarter of the slaves in Saint Domingue (later Haiti). Slavery in the French First Republic was abolished on 4 February 1794. When it became clear that Napoleon intended to re-establish slavery in Haiti, Dessalines and Pétion switched sides, in October 1802. On 1 January 1804, Jean-Jacques Dessalines, the new leader under the dictatorial 1801 constitution, declared Haiti a free republic. Thus Haiti became the second independent nation in the Western Hemisphere, after the United States, and the only successful slave rebellion in world history.

Whitehall in England announced in 1833 that slaves in its territories would be totally freed by 1840. In the meantime, the government told slaves they had to remain on their plantations and would have the status of "apprentices" for the next six years.

In Port-of-Spain, Trinidad, on 1 August 1834, an unarmed group of mainly elderly Negroes being addressed by the Governor at Government House about the new laws, began chanting: "Pas de six ans. Point de six ans" ("Not six years. No six years"), drowning out the voice of the Governor. Peaceful protests continued until a resolution to abolish apprenticeship was passed and de facto freedom was achieved. Full emancipation for all was legally granted ahead of schedule on 1 August 1838, making Trinidad the first British colony with slaves to completely abolish slavery.

In late August 1619, the frigate , a privateer ship owned by Robert Rich, 2nd Earl of Warwick, but flying a Dutch flag arrived at Point Comfort, Virginia (several miles downstream from the colony of Jamestown, Virginia) with the first recorded slaves from Africa to Virginia. The approximately 20 Africans were from the present-day Angola. They had been removed by the White Lion's crew from a Portuguese slave ship, the São João Bautista.

Only a fraction of the enslaved Africans brought to the New World came to British North America, perhaps as little as 5% of the total. The vast majority of slaves were sent to the Caribbean sugar colonies, Brazil, or Spanish America.

By the 1680s, with the consolidation of England's Royal African Company, enslaved Africans were arriving in English colonies in larger numbers, and the institution continued to be protected by the British government. Colonists now began purchasing slaves in larger numbers.

1640: Virginia courts sentence John Punch to lifetime slavery, marking the earliest legal sanctioning of slavery in English colonies.

1641: Massachusetts legalizes slavery.

1650: Connecticut legalizes slavery.

1654: Virginia sanctions "the right of Negros to own slaves of their own race" after African Anthony Johnson, former indentured servant, sued to have fellow African John Casor declared not an indentured servant but "slave for life."

1661: Virginia officially recognizes slavery by statute.

1662: A Virginia statute declares that children born would have the same status as their mother.

1663: Maryland legalizes slavery.

1664: Slavery is legalized in New York and New Jersey.

1670: Carolina (later, South Carolina and North Carolina) is founded mainly by planters from the overpopulated British sugar island colony of Barbados, who brought relatively large numbers of African slaves from that island.

The shift from indentured servants to African slaves was prompted by a dwindling class of former servants who had worked through the terms of their indentures and thus became competitors to their former masters. These newly freed servants were rarely able to support themselves comfortably, and the tobacco industry was increasingly dominated by large planters. This caused domestic unrest culminating in Bacon's Rebellion. Eventually, chattel slavery became the norm in regions dominated by plantations.

Several local slave rebellions took place during the 17th and 18th centuries: Gloucester County, Virginia Revolt (1663); New York Slave Revolt of 1712; Stono Rebellion (1739); and New York Slave Insurrection of 1741.

Within the British Empire, the Massachusetts courts began to follow England when, in 1772, England became the first country in the world to outlaw the slave trade within its borders (see Somerset v Stewart) followed by the Knight v. Wedderburn decision in Scotland in 1778. Between 1764 and 1774, seventeen slaves appeared in Massachusetts courts to sue their owners for freedom. In 1766, John Adams' colleague Benjamin Kent won the first trial in the present-day United States to free a slave (Slew vs. Whipple).

The Republic of Vermont banned slavery in its constitution of 1777 and continued the ban when it entered the United States in 1791. Through the Northwest Ordinance of 1787 under the Congress of the Confederation, slavery was prohibited in the territories north west of the Ohio River. By 1804, abolitionists succeeded in passing legislation that ended legal slavery in every northern state (with slaves above a certain age legally transformed to indentured servants). Congress banned the international importation or export of slaves on 1 January 1808; but not the internal slave trade.

Despite the actions of abolitionists, free blacks were subject to racial segregation in the Northern states. While England did not ban slavery in present-day Canada until 1833, free blacks found refugee and liberty there after the America Revolution and again after the War of 1812. Slavery in Canada was largely ended by judicial court decisions by the early nineteenth century. Refugees from slavery fled the South across the Ohio River to the North via the Underground Railroad. Midwestern state governments asserted States Rights arguments to refuse federal jurisdiction over fugitives. Some juries exercised their right of jury nullification and refused to convict those indicted under the Fugitive Slave Act of 1850.

After the passage of the Kansas-Nebraska Act in 1854, armed conflict broke out in Kansas Territory, where the question of whether it would be admitted to the Union as a slave state or a free state had been left to the inhabitants. The radical abolitionist John Brown was active in the mayhem and killing in " Bleeding Kansas." The true turning point in public opinion is better fixed at the Lecompton Constitution fraud. Pro-slavery elements in Kansas had arrived first from Missouri and quickly organized a territorial government that excluded abolitionists. Through the machinery of the territory and violence, the pro-slavery faction attempted to force an unpopular pro-slavery constitution through the state. This infuriated Northern Democrats, who supported popular sovereignty, and was exacerbated by the Buchanan administration reneging on a promise to submit the constitution to a referendum-which would surely fail. Anti-slavery legislators took office under the banner of the newly formed Republican Party. The Supreme Court in the Dred Scott decision of 1857 asserted that one could take one's property anywhere, even if one's property was chattel and one crossed into a free territory. It also asserted that African Americans could not be federal citizens. Outraged critics across the North denounced these episodes as the latest of the Slave Power (the politically organized slave owners) taking more control of the nation.

The slave population in the United States stood at four million. Ninety-five percent of blacks lived in the South, comprising one third of the population there as opposed to 1% of the population of the North. The central issue in politics in the 1850s involved the extension of slavery into the western territories, which settlers from the Northern states opposed. The Whig Party split and collapsed on the slavery issue, to be replaced in the North by the new Republican Party, which was dedicated to stopping the expansion of slavery. Republicans gained a majority in every northern state by absorbing a faction of anti-slavery Democrats, and warning that slavery was a backward system that undercut democracy and economic modernization. Numerous compromise proposals were put forward, but they all collapsed. A majority of Northern voters were committed to stopping the expansion of slavery, which they believed would ultimately end slavery. Southern voters were overwhelmingly angry that they were being treated as second-class citizens. In the election of 1860, the Republicans swept Abraham Lincoln into the Presidency and his party took control (with only 39.8% of the popular vote) and legislators into Congress. The states of the deep South, convinced that the economic power of what they called " King Cotton" would overwhelm the North and win support from Europe voted to seceded from the U.S. (the Union). They formed the Confederate States of America, based on the promise of maintaining slavery. War broke out in April 1861, as both sides sought wave after wave of enthusiasm among young men volunteering to form new regiments and new armies. In the North, the main goal was to preserve the union as an expression of American nationalism.

By 1862 most northern leaders realized that the mainstay of Southern secession, slavery, had to be attacked head-on. All the border states rejected President Lincoln's proposal for compensated emancipation. However, by 1865 all had begun the abolition of slavery, except Kentucky and Delaware. The Emancipation Proclamation was an executive order issued by Lincoln on 1 January 1863. In a single stroke, it changed the legal status, as recognized by the U.S. government, of 3 million slaves in designated areas of the Confederacy from "slave" to "free." It had the practical effect that as soon as a slave escaped the control of the Confederate government, by running away or through advances of federal troops, the slave became legally and actually free. Plantation owners, realizing that emancipation would destroy their economic system, sometimes moved their slaves as far as possible out of reach of the Union army. By June 1865, the Union Army controlled all of the Confederacy and liberated all of the designated slaves. The owners were never compensated. Over 200,000 free blacks and newly freed slaves fought for the Union in the Army and Navy, thereby validating their claims to full citizenship.

The severe dislocations of war and Reconstruction had a severe negative impact on the black population, with a large amount of sickness and death. After liberation, many of the Freedmen remained on the same plantation. Others fled or crowded into refugee camps operated by the Freedmen's Bureau. The Bureau provided food, housing, clothing, medical care, church services, some schooling, legal support, and arranged for labor contracts. Fierce debates about the rights of the Freedmen, and of the defeated Confederates, often accompanied by killings of black leaders, marked the Reconstruction Era, 1863-77.

Slavery was never reestablished, but after 1877, white Democrats took control of all the southern states and blacks lost nearly all the political power they had achieved during Reconstruction. By 1900 they also lost the right to vote. They had become second class citizens. The great majority lived in the rural South in poverty working as laborers, sharecroppers or tenant farmers; a small proportion owned their own land. The black churches, especially the Baptist Church, was the center of community activity and leadership.

Slavery in the Middle East first developed out of the slavery practices of the Ancient Near East, and these practices were radically different at times, depending on social-political factors such as the Arab slave trade. Two rough estimates by scholars of the number of slaves held over twelve centuries in Muslim lands are 11.5 million and 14 million.

Under Sharia (Islamic law), children of slaves or prisoners of war could become slaves but only non-Muslims. Manumission of a slave was encouraged as a way of expiating sins. Many early converts to Islam, such as Bilal ibn Rabah al-Habashi, were the poor and former slaves. In theory, slavery in Islamic law does not have a racial or color component, although this has not always been the case in practice.

Bernard Lewis writes: "In one of the sad paradoxes of human history, it was the humanitarian reforms brought by Islam that resulted in a vast development of the slave trade inside, and still more outside, the Islamic empire." He notes that the Islamic injunctions against the enslavement of Muslims led to massive importation of slaves from the outside. According to Patrick Manning, Islam by recognizing and codifying the slavery seems to have done more to protect and expand slavery than the reverse.

Slavery was a legal and important part of the economy of the Ottoman Empire and Ottoman society until the slavery of Caucasians was banned in the early 19th century, although slaves from other groups were allowed. In Constantinople (present-day Istanbul), the administrative and political center of the Empire, about a fifth of the population consisted of slaves in 1609. Even after several measures to ban slavery in the late 19th century, the practice continued largely unfazed into the early 20th century. As late as 1908, female slaves were still sold in the Ottoman Empire. Sexual slavery was a central part of the Ottoman slave system throughout the history of the institution.

A member of the Ottoman slave class, called a in Turkish, could achieve high status. Harem guards and janissaries are some of the better-known positions a slave could hold, but slaves were actually often at the forefront of Ottoman politics. The majority of officials in the Ottoman government were bought slaves, raised free, and integral to the success of the Ottoman Empire from the 14th century into the 19th. Many officials themselves owned a large number of slaves, although the Sultan himself owned by far the largest amount. By raising and specially training slaves as officials in palace schools such as Enderun, the Ottomans created administrators with intricate knowledge of government and fanatic loyalty.

Ottomans practiced , a sort of "blood tax" or "child collection", young Christian boys from the Balkans and Anatolia were taken from their homes and families, brought up as Muslims, and enlisted into the most famous branch of the , the Janissaries, a special soldier class of the Ottoman army that became a decisive faction in the Ottoman invasions of Europe.

During the various 18th and 19th century persecution campaigns against Christians as well as during the culminating Assyrian, Armenian and Greek genocides of World War I, many indigenous Armenian, Assyrian and Greek Christian women and children were carried off as slaves by the Ottoman Turks and their Kurdish allies. Henry Morgenthau, Sr., U.S. Ambassador in Constantinople from 1913 to 1916, reports in his Ambassador Morgenthau's Story that there were gangs trading white slaves during his term in Constantinople. He also reports that Armenian girls were sold as slaves during the Armenian Genocide.

The Arab or Islamic slave trade lasted much longer than the Atlantic or European slave trade: "It began in the middle of the seventh century and survives today in Mauritania and Sudan. With the Islamic slave trade, we're talking of 14 centuries rather than four." Further, "whereas the gender ratio of slaves in the Atlantic trade was two males to every female, in the Islamic trade, it was two females to every male," according to Ronald Segal

According to media reports from late 2014 the Islamic State of Iraq and the Levant (ISIL) was selling Yazidi and Christian women as slaves. According to Haleh Esfandiari of the Woodrow Wilson International Center for Scholars, after ISIL militants have captured an area "[t]hey usually take the older women to a makeshift slave market and try to sell them." In mid-October 2014, the UN estimated that 5,000 to 7,000 Yazidi women and children were abducted by ISIL and sold into slavery. In the digital magazine , ISIL claimed religious justification for enslaving Yazidi women whom they consider to be from a heretical sect. ISIL claimed that the Yazidi are idol worshipers and their enslavement is part of the old shariah practice of spoils of war. According to The Wall Street Journal, ISIL appeals to apocalyptic beliefs and claims "justification by a Hadith that they interpret as portraying the revival of slavery as a precursor to the end of the world".

ISIL announced the revival of slavery as an institution. In 2015 the official slave prices set by ISIL were following:

Children aged 1 to 9 were sold for 200,000 dinars ($169).

Women and children 10 to 20 years old for 150,000 dinars ($127).

Women 20 to 30 years old for 100,000 dinar ($85).

Women 30 to 40 years old are 75,000 dinar ($63).

Women 40 to 50 years old for 50,000 dinar ($42).

However some slaves have been sold for as little as a pack of cigarettes. Sex slaves were sold to Saudi Arabia, other Persian Gulf states and Turkey.

Slavery has existed all throughout Asia, and forms of slavery still exist today.

Scholars differ as to whether or not slaves and the institution of slavery existed in ancient India. These English words have no direct, universally accepted equivalent in Sanskrit or other Indian languages, but some scholars translate the word , mentioned in texts like Manu Smriti, as slaves. Ancient historians who visited India offer the closest insights into the nature of Indian society and slavery in other ancient civilizations. For example, the Greek historian Arrian, who chronicled India about the time of Alexander the Great, wrote in his Indika,

The Indians do not even use aliens as slaves, much less a countryman of their own.

Qin dynasty (221-206 BC) Men sentenced to castration became eunuch slaves of the Qin dynasty state and as a result they were made to do forced labor, on projects like the Terracotta Army. The Qin government confiscated the property and enslaved the families of those who received castration as a punishment for rape.
Slaves were deprived of their rights and connections to their families.

Han dynasty (206 BC - 220 AD) One of Emperor Gao's first acts was to set free from slavery agricultural workers who were enslaved during the Warring States period, although domestic servants retained their status.

Men punished with castration during the Han dynasty were also used as slave labor.

Deriving from earlier Legalist laws, the Han dynasty set in place rules that the property of and families of criminals doing three years of hard labor or sentenced to castration were to have their families seized and kept as property by the government.

During the millennium long Chinese domination of Vietnam, Vietnam was a great source of slave girls who were used as sex slaves in China. The slave girls of Viet were even eroticized in Tang dynasty poetry.

The Islamic invasions, starting in the 8th century, also resulted in hundreds of thousands of Indians being enslaved by the invading armies, one of the earliest being the armies of the Umayyad commander Muhammad bin Qasim. Qutb-ud-din Aybak, a Turkic slave of Muhammad Ghori rose to power following his master's death. For almost a century, his descendants ruled North-Central India in form of Slave Dynasty. Several slaves were also brought to India by the Indian Ocean trades; for example, the Siddi are descendants of Bantu slaves brought to India by Arab and Portuguese merchants.

Andre Wink summarizes the slavery in 8th and 9th century India as follows,

(During the invasion of Muhammad al-Qasim), invariably numerous women and children were enslaved. The sources insist that now, in dutiful conformity to religious law, 'the one-fifth of the slaves and spoils' were set apart for the caliph's treasury and despatched to Iraq and Syria. The remainder was scattered among the army of Islam. At Rūr, a random 60,000 captives reduced to slavery. At Brahamanabad 30,000 slaves were allegedly taken. At Multan 6,000. Slave raids continued to be made throughout the late Umayyad period in Sindh, but also much further into Hind, as far as Ujjain and Malwa. The Abbasid governors raided Punjab, where many prisoners and slaves were taken.

In the early 11th century Tarikh al-Yamini, the Arab historian Al-Utbi recorded that in 1001 the armies of Mahmud of Ghazna conquered Peshawar and Waihand (capital of Gandhara) after Battle of Peshawar (1001), "in the midst of the land of Hindustan", and captured some 100,000 youths. Later, following his twelfth expedition into India in 1018-19, Mahmud is reported to have returned with such a large number of slaves that their value was reduced to only two to ten dirhams each. This unusually low price made, according to Al-Utbi, "merchants [come] from distant cities to purchase them, so that the countries of Central Asia, Iraq and Khurasan were swelled with them, and the fair and the dark, the rich and the poor, mingled in one common slavery". Elliot and Dowson refer to "five hundred thousand slaves, beautiful men and women.". Later, during the Delhi Sultanate period (1206-1555), references to the abundant availability of low-priced Indian slaves abound. Levi attributes this primarily to the vast human resources of India, compared to its neighbors to the north and west (India's Mughal population being approximately 12 to 20 times that of Turan and Iran at the end of the 16th century).

Slavery and empire-formation tied in particularly well with iqta and it is within this context of Islamic expansion that elite slavery was later commonly found. It became the predominant system in North India in the thirteenth century and retained considerable importance in the fourteenth century. Slavery was still vigorous in fifteenth-century Bengal, while after that date it shifted to the Deccan where it persisted until the seventeenth century. It remained present to a minor extent in the Mughal provinces throughout the seventeenth century and had a notable revival under the Afghans in North India again in the eighteenth century.

The Delhi sultanate obtained thousands of slaves and eunuch servants from the villages of Eastern Bengal (a widespread practice which Mughal emperor Jahangir later tried to stop). Wars, famines, pestilences drove many villagers to sell their children as slaves. The Muslim conquest of Gujarat in Western India had two main objectives. The conquerors demanded and more often forcibly wrested both land owned by Hindus and Hindu women. Enslavement of women invariably led to their conversion to Islam. In battles waged by Muslims against Hindus in Malwa and Deccan plateau, a large number of captives were taken. Muslim soldiers were permitted to retain and enslave POWs as plunder.

The first Bahmani sultan, Alauddin Bahman Shah is noted to have captured 1,000 singing and dancing girls from Hindu temples after he battled the northern Carnatic chieftains. The later Bahmanis also enslaved civilian women and children in wars; many of them were converted to Islam in captivity. About the Mughal empire, W.H. Moreland observed, "it became a fashion to raid a village or group of villages without any obvious justification, and carry off the inhabitants as slaves."

During the rule of Shah Jahan, many peasants were compelled to sell their women and children into slavery to meet the land revenue demand. Slavery was officially abolished in British India by the Indian Slavery Act, 1843. However, in modern India, Pakistan and Nepal, there are millions of bonded laborers, who work as slaves to pay off debts.

The Tang dynasty purchased Western slaves from the Radanite Jews. Tang Chinese soldiers and pirates enslaved Koreans, Turks, Persians, Indonesians, and people from Inner Mongolia, Central Asia, and northern India. The greatest source of slaves came from southern tribes, including Thais and aboriginals from the southern provinces of Fujian, Guangdong, Guangxi, and Guizhou. Malays, Khmers, Indians, and black Africans were also purchased as slaves in the Tang dynasty. Slavery was prevalent until the late 19th century and early 20th century China. All forms of slavery have been illegal in China since 1910.

Slavery in Japan was, for most of its history, indigenous, since the export and import of slaves was restricted by Japan being a group of islands. In late-16th-century Japan, slavery was officially banned; but forms of contract and indentured labor persisted alongside the period penal codes' forced labor. During the Second Sino-Japanese War and the Pacific War, the Japanese military used millions of civilians and prisoners of war from several countries as forced laborers.

In Korea, slavery was officially abolished with the Gabo Reform of 1894. During the Joseon period, in times of poor harvest and famine, many peasants voluntarily sold themselves into the nobi system in order to survive.

In Southeast Asia, there was a large slave class in Khmer Empire who built the enduring monuments in Angkor Wat and did most of the heavy work. Between the 17th and the early 20th centuries one-quarter to one-third of the population of some areas of Thailand and Burma were slaves. By the 19th century, Bhutan had developed a slave trade with Sikkim and Tibet, also enslaving British subjects and Brahmins. According to the International Labour Organization (ILO), during the early 21st century an estimated 800,000 people are subject to forced labor in Myanmar.

Slavery in pre-Spanish Philippines was practiced by the tribal Austronesian peoples who inhabited the culturally diverse islands. The neighbouring Muslim states conducted slave raids from the 1600s into the 1800s in coastal areas of the Gulf of Thailand and the Philippine islands. Slaves in Toraja society in Indonesia were family property. People would become slaves when they incurred a debt. Slaves could also be taken during wars, and slave trading was common. Torajan slaves were sold and shipped out to Java and Siam. Slaves could buy their freedom, but their children still inherited slave status. Slavery was abolished in 1863 in all Dutch colonies.

Records of slavery in Ancient Greece go as far back as Mycenaean Greece. The origins are not known, but it appears that slavery became an important part of the economy and society only after the establishment of cities. Slavery was common practice and an integral component of ancient Greece, as it was in other societies of the time, including ancient Israel. It is estimated that in Athens, the majority of citizens owned at least one slave. Most ancient writers considered slavery not only natural but necessary, but some isolated debate began to appear, notably in Socratic dialogues. The Stoics produced the first condemnation of slavery recorded in history.

During the 8th and the 7th centuries BC, in the course of the two Messenian Wars, the Spartans reduced an entire population to a pseudo-slavery called . According to Herodotus (IX, 28-29), helots were seven times as numerous as Spartans. Following several helot revolts around the year 600 BC, the Spartans restructured their city-state along authoritarian lines, for the leaders decided that only by turning their society into an armed camp could they hope to maintain control over the numerically dominant helot population. In some Ancient Greek city-states, about 30% of the population consisted of slaves, but paid and slave labor seem to have been equally important.

Romans inherited the institution of slavery from the Greeks and the Phoenicians. As the Roman Republic expanded outward, it enslaved entire populations, thus ensuring an ample supply of laborers to work in Rome's farms, quarries and households. The people subjected to Roman slavery came from all over Europe and the Mediterranean. Such oppression by an elite minority eventually led to slave revolts; the Third Servile War led by Spartacus was the most famous and severe. Greeks, Berbers, Germans, Britons, Slavs, Thracians, Gauls (or Celts), Jews, Arabs and many more ethnic groups were enslaved to be used for labor, and also for amusement (e.g. gladiators and sex slaves). If a slave ran away, they were liable to be crucified.

The overall impact of slavery on the Italian genetics was insignificant though, because the slaves imported in Italy were native Europeans, and very few if any of them had extra European origin. This has been further confirmed by recent biochemical analysis of 166 skeletons from three non-elite imperial-era cemeteries in the vicinity of Rome (where the bulk of the slaves lived), which shows that only 1 individual definitely came from outside of Europe (North Africa), and another 2 possibly did, but results are inconclusive. In the rest of the Italian peninsula, the amount of non European slaves was definitively much lower than that.

The chaos of invasion and frequent warfare also resulted in victorious parties taking slaves throughout Europe in the early Middle Ages. St. Patrick, himself captured and sold as a slave, protested against an attack that enslaved newly baptized Christians in his "Letter to the Soldiers of Coroticus". As a commonly traded commodity, like cattle, slaves could become a form of internal or trans-border currency. Slavery during the Early Middle Ages had several distinct sources.

The Vikings raided across Europe, but took the most slaves in raids on the British Isles and in Eastern Europe. While the Vikings kept some slaves as servants, known as , they sold most captives in the Byzantine or Islamic markets. In the West, their target populations were primarily English, Irish, and Scottish, while in the East they were mainly Slavs. The Viking slave-trade slowly ended in the 11th century, as the Vikings settled in the European territories they had once raided. They converted serfs to Christianity and themselves merged with the local populace.

In central Europe, specifically the Frankish/German/Holy Roman Empire of Charlemagne, raids and wars to the east generated a steady supply of slaves from the Slavic captives of these regions. Because of high demand for slaves in the wealthy Muslim empires of Northern Africa, Spain, and the Near East, especially for slaves of European descent, a market for these slaves rapidly emerged. So lucrative was this market that it spawned an economic boom in central and western Europe, today known as the Carolingian Renaissance. This boom period for slaves stretched from the early Muslim conquests to the High Middle Ages but declined in the later Middle Ages as the Islamic Golden Age waned.

Medieval Spain and Portugal saw almost constant warfare between Muslims and Christians. Al-Andalus sent periodic raiding expeditions to loot the Iberian Christian kingdoms, bringing back booty and slaves. In a raid against Lisbon, Portugal in 1189, for example, the Almohad caliph Yaqub al-Mansur took 3,000 female and child captives. In a subsequent attack upon Silves, Portugal in 1191, his governor of Córdoba took 3,000 Christian slaves.

The Byzantine-Ottoman wars and the Ottoman wars in Europe resulted in the taking of large numbers of Christian slaves and using or selling them in the Islamic world too. After the battle of Lepanto the victors freed approximately 12,000 Christian galley slaves from the Ottoman fleet.

Similarly, Christians sold Muslim slaves captured in war. The Order of the Knights of Malta attacked pirates and Muslim shipping, and their base became a centre for slave trading, selling captured North Africans and Turks. Malta remained a slave market until well into the late 18th century. One thousand slaves were required to man the galleys (ships) of the Order.

Poland banned slavery in the 15th century; in Lithuania, slavery was formally abolished in 1588; the institution was replaced by the second enserfment. Slavery remained a minor institution in Russia until 1723, when Peter the Great converted the household slaves into house serfs. Russian agricultural slaves were formally converted into serfs earlier, in 1679. The escaped Russian serfs and kholops formed autonomous communities in the southern steppes, where they became known as Cossacks (meaning "outlaws").

Capture in war, voluntary servitude and debt slavery became common within the British Isles before 1066. Slaves were routinely bought and sold. Running away was also common and slavery was never a major economic factor in the British Isles during the Middle Ages. Ireland and Denmark provided markets for captured Anglo-Saxon and Celtic slaves. Pope Gregory I reputedly made the pun, Non Angli, sed Angeli ("Not Angles, but Angels"), after a response to his query regarding the identity of a group of fair-haired Angles, slave children whom he had observed in the marketplace. After the Norman Conquest, the law no longer supported chattel slavery and slaves became part of the larger body of serfs.

Barbary pirates and Maltese corsairs both raided for slaves and purchased slaves from European merchants, often the Radhanites, one of the few groups who could easily move between the Christian and Islamic worlds.

In the late Middle Ages, from 1100 to 1500, the European slave-trade continued, though with a shift from being centered among the Western Mediterranean Islamic nations to the Eastern Christian and Muslim states. The city-states of Venice and Genoa controlled the Eastern Mediterranean from the 12th century and the Black Sea from the 13th century. They sold both Slavic and Baltic slaves, as well as Georgians, Turks, and other ethnic groups of the Black Sea and Caucasus. The sale of European slaves by Europeans slowly ended as the Slavic and Baltic ethnic groups Christianized by the Late Middle Ages. European slaves did not pass on an inherited status and was thus more akin to forced labor, or indentured servitude.

From the 1440s into the 18th century, Europeans from Italy, Spain, Portugal, France, and England were sold into slavery by North Africans, as described in the book "Christian Slaves, Muslim Masters". This same book states that "white slavery had been minimised or ignored because academics preferred to treat Europeans as evil colonialists rather than as victims." and likely overestimates the number of slaves taken. In 1575, the Tatars captured over 35,000 Ukrainians; a 1676 raid took almost 40,000. About 60,000 Ukrainians were captured in 1688; some were ransomed, but most were sold into slavery. Some of the Roma people were enslaved over five centuries in Romania until abolition in 1864 (see Slavery in Romania).

The Mongol invasions and conquests in the 13th century also resulted in taking numerous captives into slavery. The Mongols enslaved skilled individuals, women and children and marched them to Karakorum or Sarai, whence they were sold throughout Eurasia. Many of these slaves were shipped to the slave market in Novgorod.

Slave commerce during the Late Middle Ages was mainly in the hands of Venetian and Genoese merchants and cartels, who were involved in the slave trade with the Golden Horde. In 1382 the Golden Horde under Khan Tokhtamysh sacked Moscow, burning the city and carrying off thousands of inhabitants as slaves. Between 1414 and 1423, some 10,000 eastern European slaves were sold in Venice. Genoese merchants organized the slave trade from the Crimea to Mamluk Egypt. For years, the Khanates of Kazan and Astrakhan routinely made raids on Russian principalities for slaves and to plunder towns. Russian chronicles record about 40 raids by Kazan Khans on the Russian territories in the first half of the 16th century.

In 1441 Haci I Giray declared independence from the Golden Horde and established the Crimean Khanate. For a long time, until the early 18th century, the khanate maintained an extensive slave-trade with the Ottoman Empire and the Middle East. In a process called the "harvesting of the steppe" they enslaved many Slavic peasants. About 30 major Tatar raids were recorded into Muscovite territories between 1558 and 1596.

Moscow was repeatedly a target. In 1521, the combined forces of Crimean Khan Mehmed Giray and his Kazan allies attacked the city and captured thousands of slaves. In 1571, the Crimean Tatars attacked and sacked Moscow, burning everything but the Kremlin and taking thousands of captives as slaves. In Crimea, about 75% of the population consisted of slaves.

In the Viking era beginning circa 793, the Norse raiders often captured and enslaved militarily weaker peoples they encountered. The Nordic countries called their slaves ( Old Norse: Þræll). The thralls were mostly from Western Europe, among them many Franks, Frisians, Anglo-Saxons, and both Irish and Britonnic Celts. Many Irish slaves travelled in expeditions for the colonization of Iceland. The Norse also took German, Baltic, Slavic and Latin slaves. The slave trade was one of the pillars of Norse commerce during the 6th through 11th centuries. The 10th-century Persian traveller Ibn Rustah described how Swedish Vikings, the Varangians or Rus, terrorized and enslaved the Slavs taken in their raids along the Volga River. The thrall system was finally abolished in the mid-14th century in Scandinavia.

Mediterranean powers frequently sentenced convicted criminals to row in the war- galleys of the state (initially only in time of war). After the revocation of the Edict of Nantes in 1685 and Camisard rebellion, the French Crown filled its galleys with French Huguenots, Protestants condemned for resisting the state. Galley-slaves lived and worked in such harsh conditions that many did not survive their terms of sentence, even if they survived shipwreck and slaughter or torture at the hands of enemies or of pirates. Naval forces often turned 'infidel' prisoners-of-war into galley-slaves. Several well-known historical figures served time as galley slaves after being captured by the enemy-the Ottoman corsair and admiral Turgut Reis and the Knights Hospitaller Grand Master Jean Parisot de la Valette among them.

Denmark-Norway was the first European country to ban the slave trade. This happened with a decree issued by King Christian VII of Denmark in 1792, to become fully effective by 1803. Slavery as an institution was not banned until 1848. At this time Iceland was a part of Denmark-Norway but slave trading had been abolished in Iceland in 1117 and had never been reestablished.

Slavery in the French Republic was abolished on 4 February 1794, including in its colonies. The lengthy Haitian Revolution by its slaves and free people of color established Haiti as a free republic in 1804 ruled by blacks, the first of its kind. At the time of the revolution, Haiti was known as Saint-Domingue and was a colony of France. Napoleon Bonaparte gave up on Haiti in 1803, but re-established slavery in Guadeloupe and Martinique in 1804, at the request of planters of the Caribbean colonies. Slavery was permanently abolished in the French empire during the French Revolution of 1848.

The 15th-century Portuguese exploration of the African coast is commonly regarded as the harbinger of European colonialism. In 1452, Pope Nicholas V issued the papal bull Dum Diversas, granting Afonso V of Portugal the right to reduce any "Saracens, pagans and any other unbelievers" to hereditary slavery which legitimized slave trade under Catholic beliefs of that time. This approval of slavery was reaffirmed and extended in his Romanus Pontifex bull of 1455. These papal bulls came to serve as a justification for the subsequent era of the slave trade and European colonialism. Although for a short period as in 1462, Pius II declared slavery to be "a great crime". The followers of the church of England and Protestants did not use the papal bull as a justification. The position of the church was to condemn the slavery of Christians, but slavery was regarded as an old established and necessary institution which supplied Europe with the necessary workforce. In the 16th century, African slaves had replaced almost all other ethnicities and religious enslaved groups in Europe. Within the Portuguese territory of Brazil, and even beyond its original borders, the enslavement of Native Americans was carried out by the Bandeirantes.

Among many other European slave markets, Genoa, and Venice were some well-known markets, their importance and demand growing after the great plague of the 14th century which decimated much of the European workforce. The maritime town of Lagos, Portugal, was the first slave market created in Portugal for the sale of imported African slaves, the Mercado de Escravos, which opened in 1444. In 1441, the first slaves were brought to Portugal from northern Mauritania. Prince Henry the Navigator, major sponsor of the Portuguese African expeditions, as of any other merchandise, taxed one fifth of the selling price of the slaves imported to Portugal. By the year 1552 African slaves made up 10 percent of the population of Lisbon. In the second half of the 16th century, the Crown gave up the monopoly on slave trade and the focus of European trade in African slaves shifted from import to Europe to slave transports directly to tropical colonies in the Americas-in the case of Portugal, especially Brazil. In the 15th century, one-third of the slaves were resold to the African market in exchange of gold. Slavery was abolished in mainland Portugal and Portuguese India in 1761. It was finally abolished in all Portuguese colonies in 1869.

The Spaniards were the first Europeans to use African slaves in the New World on islands such as Cuba and Hispaniola, due to a shortage of labor caused by the spread of diseases, and so the Spanish colonists gradually became involved in the Atlantic slave trade. The first African slaves arrived in Hispaniola in 1501; by 1517, the natives had been "virtually annihilated" mostly to diseases. The problem of the justness of Native American's slavery was a key issue for the Spanish Crown. It was Charles V who gave a definite answer to this complicated and delicate matter. To that end, on 25 November 1542, the Emperor abolished slavery by decree in his Leyes Nuevas New Laws. This bill was based on the arguments given by the best Spanish theologists and jurists who were unanimous in the condemnation of such slavery as unjust; they declared it illegitimate and outlawed it from America-not just the slavery of Spaniards over Natives-but also the type of slavery practiced among the Natives themselves Thus, Spain became the first country to officially abolish slavery.

However, in the Spanish colonies of Cuba and Puerto Rico, where sugarcane production was highly profitable based on slave labor, African slavery persisted until 1873 in Puerto Rico "with provisions for periods of apprenticeship", and 1886 in Cuba.

Although slavery was illegal inside the Netherlands it flourished throughout the Dutch Empire in the Americas, Africa, Ceylon and Indonesia. The Dutch Slave Coast ( Dutch: Slavenkust) referred to the trading posts of the Dutch West India Company on the Slave Coast, which lie in contemporary Ghana, Benin, Togo and Nigeria. Initially the Dutch shipped slaves to northern Brazil, and during the second half of the 17th century they had a controlling interest in the trade to the Spanish colonies. Today's Suriname and Guyana became prominent markets in the 18th century. Between 1612 and 1872, the Dutch operated from some 10 fortresses along the Gold Coast (now Ghana), from which slaves were shipped across the Atlantic. Dutch involvement on the Slave Coast increased with the establishment of a trading post in Offra in 1660. Willem Bosman writes in his Nauwkeurige beschrijving van de Guinese Goud- Tand- en Slavekust (1703) that Allada was also called Grand Ardra, being the larger cousin of Little Ardra, also known as Offra. From 1660 onward, Dutch presence in Allada and especially Offra became more permanent. A report from this year asserts Dutch trading posts, apart from Allada and Offra, in Benin City, Grand-Popo, and Savi.

The Offra trading post soon became the most important Dutch office on the Slave Coast. According to a 1670 report, annually 2,500 to 3,000 slaves were transported from Offra to the Americas. These numbers were only feasible in times of peace, however, and dwindled in time of conflict. From 1688 onward, the struggle between the Aja king of Allada and the peoples on the coastal regions, impeded the supply of slaves. The Dutch West India Company chose the side of the Aja king, causing the Offra office to be destroyed by opposing forces in 1692. By 1650 the Dutch had the pre-eminent slave trade in Europe and South East Asia. Later, trade shifted to Ouidah. On the instigation of Governor-General of the Dutch Gold Coast Willem de la Palma, Jacob van den Broucke was sent in 1703 as "opperkommies" (head merchant) to the Dutch trading post at Ouidah, which according to sources was established around 1670. Political unrest caused the Dutch to abandon their trading post at Ouidah in 1725, and they then moved to Jaquim, at which place they built Fort Zeelandia. The head of the post, Hendrik Hertog, had a reputation for being a successful slave trader. In an attempt to extend his trading area, Hertog negotiated with local tribes and mingled in local political struggles. He sided with the wrong party, however, leading to a conflict with Director-General Jan Pranger and to his exile to the island of Appa in 1732. The Dutch trading post on this island was extended as the new centre of the slave trade. In 1733, Hertog returned to Jaquim, this time extending the trading post into Fort Zeelandia. The revival of the slave trade at Jaquim was only temporary, however, as his superiors at the Dutch West India Company noticed that Hertog's slaves were more expensive than at the Gold Coast. From 1735, Elmina became the preferred spot to trade slaves. As of 1778, it was estimated that the Dutch were shipping approximately 6,000 Africans for enslavement in the Dutch West Indies each year. Slavery also characterised the Dutch possessions in Indonesia, Ceylon and South Africa, where Indonesians have made a significant contribution to the Cape Coloured population of that country. The Dutch part in the Atlantic slave trade is estimated at 5-7 percent, as they shipped about 550,000-600,000 African slaves across the Atlantic, about 75,000 of whom died on board before reaching their destinations. From 1596 to 1829, the Dutch traders sold 250,000 slaves in the Dutch Guianas, 142,000 in the Dutch Caribbean islands, and 28,000 in Dutch Brazil. In addition, tens of thousands of slaves, mostly from India and some from Africa, were carried to the Dutch East Indies. The Netherlands was one of the last countries to abolish slavery in 1863. Although the decision was made in 1848, it took many years for the law to be implemented. Furthermore, slaves in Suriname would be fully free only in 1873, since the law stipulated that there was to be a mandatory 10-year transition.

Barbary Corsairs continued to trade in European slaves into the Modern time-period. Muslim pirates, primarily Algerians with the support of the Ottoman Empire, raided European coasts and shipping from the 16th to the 19th centuries, and took thousands of captives, whom they sold or enslaved. Many were held for ransom, and European communities raised funds such as Malta's Monte della Redenzione degli Schiavi to buy back their citizens. The raids gradually ended with the naval decline of the Ottoman Empire in the late 16th and 17th centuries, as well as the European conquest of North Africa throughout the 19th century.

From 1609 to 1616, England lost 466 merchant ships to Barbary pirates. 160 English ships were captured by Algerians between 1677 and 1680. Many of the captured sailors were made into slaves and held for ransom. The corsairs were no strangers to the South West of England where raids were known in a number of coastal communities. In 1627 Barbary Pirates under command of the Dutch renegade Jan Janszoon (Murat Reis), operating from the Moroccan port of Salé, occupied the island of Lundy. During this time there were reports of captured slaves being sent to Algiers.

Ireland, despite its northern position, was not immune from attacks by the corsairs. In June 1631 Janszoon, with pirates from Algiers and armed troops of the Ottoman Empire, stormed ashore at the little harbor village of Baltimore, County Cork. They captured almost all the villagers and took them away to a life of slavery in North Africa. The prisoners were destined for a variety of fates-some lived out their days chained to the oars as galley slaves, while others would spend long years in the scented seclusion of the harem or within the walls of the sultan's palace. Only two of them ever saw Ireland again.

The Congress of Vienna (1814-15), which ended the Napoleonic Wars, led to increased European consensus on the need to end Barbary raiding. The sacking of Palma on the island of Sardinia by a Tunisian squadron, which carried off 158 inhabitants, roused widespread indignation. Britain had by this time banned the slave trade and was seeking to induce other countries to do likewise. States that were more vulnerable to the corsairs complained that Britain cared more for ending the trade in African slaves than stopping the enslavement of Europeans and Americans by the Barbary States.

In order to neutralise this objection and further the anti-slavery campaign, in 1816 Britain sent Lord Exmouth to secure new concessions from Tripoli, Tunis, and Algiers, including a pledge to treat Christian captives in any future conflict as prisoners of war rather than slaves. He imposed peace between Algiers and the kingdoms of Sardinia and Sicily. On his first visit, Lord Exmouth negotiated satisfactory treaties and sailed for home. While he was negotiating, a number of Sardinian fishermen who had settled at Bona on the Tunisian coast were brutally treated without his knowledge. As Sardinians they were technically under British protection, and the government sent Exmouth back to secure reparation. On 17 August, in combination with a Dutch squadron under Admiral Van de Capellen, Exmouth bombarded Algiers. Both Algiers and Tunis made fresh concessions as a result.

The Barbary states had difficulty securing uniform compliance with a total prohibition of slave-raiding, as this had been traditionally of central importance to the North African economy. Slavers continued to take captives by preying on less well-protected peoples. Algiers subsequently renewed its slave-raiding, though on a smaller scale. Europeans at the Congress of Aix-la-Chapelle in 1818 discussed possible retaliation. In 1820 a British fleet under Admiral Sir Harry Neal bombarded Algiers. Corsair activity based in Algiers did not entirely cease until France conquered the state in 1830.

The Crimeans frequently mounted raids into the Danubian principalities, Poland-Lithuania, and Muscovy to enslave people whom they could capture; for each captive, the khan received a fixed share (savğa) of 10% or 20%. These campaigns by Crimean forces were either sefers ("sojourns" - officially declared military operations led by the khans themselves), or çapuls ("despoiling" - raids undertaken by groups of noblemen, sometimes illegally because they contravened treaties concluded by the khans with neighbouring rulers).

For a long time, until the early 18th century, the Crimean Khanate maintained a massive slave trade with the Ottoman Empire and the Middle East, exporting about 2 million slaves from Russia and Poland-Lithuania over the period 1500-1700. Caffa (modern Feodosia) became one of the best-known and significant trading ports and slave markets. In 1769 the last major Tatar raid saw the capture of 20,000 Russian and Ruthenian slaves.

Author and historian Brian Glyn Williams writes:

Fisher estimates that in the sixteenth century the Polish-Lithuanian Commonwealth lost around 20,000 individuals a year and that from 1474 to 1694, as many as a million Commonwealth citizens were carried off into Crimean slavery.

Early modern sources are full of descriptions of sufferings of Christian slaves captured by the Crimean Tatars in the course of their raids:

It seems that the position and everyday conditions of a slave depended largely on his/her owner. Some slaves indeed could spend the rest of their days doing exhausting labor: as the Crimean vizir (minister) Sefer Gazi Aga mentions in one of his letters, the slaves were often "a plough and a scythe" of their owners. Most terrible, perhaps, was the fate of those who became galley-slaves, whose sufferings were poeticized in many Ukrainian dumas (songs). ... Both female and male slaves were often used for sexual purposes.

Britain played a prominent role in the Atlantic slave trade, especially after 1640, when sugar cane was introduced to the region. At first, most were white Britons, or Irish, enslaved as indentured labour - for a fixed period - in the West Indies. These people may have been criminals, political rebels, the poor with no prospects or others who were simply tricked or kidnapped. Slavery was a legal institution in all of the 13 American colonies and Canada (acquired by Britain in 1763). The profits of the slave trade and of West Indian plantations amounted to 5% of the British economy at the time of the Industrial Revolution.

A little-known incident in the career of Judge Jeffreys refers to an assize in Bristol in 1685 when he made the mayor of the city, then sitting fully robed beside him on the bench, go into the dock and be fined £1000 for being a 'kidnapping knave'; some Bristol traders at the time were known at the time to kidnap their own countrymen and ship them away as slaves.

Somersett's case in 1772 was generally taken at the time to have decided that the condition of slavery did not exist under English law in England. In 1785, English poet William Cowper wrote: "We have no slaves at home - Then why abroad? Slaves cannot breathe in England; if their lungs receive our air, that moment they are free. They touch our country, and their shackles fall. That's noble, and bespeaks a nation proud. And jealous of the blessing. Spread it then, And let it circulate through every vein." However, slavery continued to thrive in England itself, much like it did in the British Empire, until full emancipation in the 1830s. In 1807, following many years of lobbying by the abolitionist movement, led primarily by William Wilberforce, the British Parliament voted to make the slave trade illegal anywhere in the Empire with the Slave Trade Act 1807. Thereafter Britain took a prominent role in combating the trade, and slavery itself was abolished in the British Empire (except for India) with the Slavery Abolition Act 1833. Between 1808 and 1860, the West Africa Squadron seized approximately 1,600 slave ships and freed 150,000 Africans who were aboard. Action was also taken against African leaders who refused to agree to British treaties to outlaw the trade. Akitoye, the 11th Oba of Lagos, is famous for having used British involvement to regain his rule in return for suppressing slavery among the Yoruba people of Lagos in 1851. Anti-slavery treaties were signed with over 50 African rulers. In 1839, the world's oldest international human rights organization, Anti-Slavery International, was formed in Britain by Joseph Sturge, which worked to outlaw slavery in other countries.

After 1833, the freed African slaves declined employment in the cane fields. This led to the importation of indentured labour again - mainly from India, and also China.

In 1811, Arthur William Hodge was executed for the murder of a slave in the British West Indies. He was not, however, as some have claimed, the first white person to have been lawfully executed for the murder of a slave.

During World War II Nazi Germany operated several categories of Arbeitslager (Labor Camps) for different categories of inmates. The largest number of them held Polish and Jewish civilians forcibly abducted in the occupied countries (see Łapanka) to provide labor in the German war industry, repair bombed railroads and bridges or work on farms. By 1944, 20% of all workers were foreigners, either civilians or prisoners of war.

This is not classed as slavery per se, as defined in the first paragraph, i.e. slavery under this definition does not include other forced labour systems, such as historical forced labor by prisoners, labor camps, or other forms of unfree labor, in which labourers are not legally considered property. Slavery typically requires a shortage of labor and a surplus of land to be viable.

As agreed by the Allies at the Yalta conference Germans were used as forced labor as part of the reparations to be extracted. By 1947 it is estimated that 400,000 Germans (both civilians and POWs) were being used as forced labor by the U.S., France, the UK and the Soviet Union. German prisoners were for example forced to clear minefields in France and the Low Countries. By December 1945 it was estimated by French authorities that 2,000 German prisoners were being killed or injured each month in accidents. In Norway the last available casualty record, from 29 August 1945, shows that by that time a total of 275 German soldiers died while clearing mines, while 392 had been injured. Death rates for the German civilians doing forced labor in the Soviet Union ranged between 19% and 39%, depending on category.

In the first half of the 19th century, small-scale slave raids took place across Polynesia to supply labor and sex workers for the whaling and sealing trades, with examples from both the westerly and easterly extremes of the Polynesian triangle. By the 1860s this had grown to a larger scale operation with Peruvian slave raids in the South Sea Islands to collect labor for the guano industry.

Ancient Hawaii was a caste society. People were born into specific social classes. Kauwa were those of the outcast or slave class. They are believed to have been war captives, or the descendants of war captives. Marriage between higher castes and the kauwa was strictly forbidden. The kauwa worked for the chiefs and were often used as human sacrifices at the luakini heiau. (They were not the only sacrifices; law-breakers of all castes or defeated political opponents were also acceptable as victims.)

The kapu system was abolished during the ʻAi Noa in 1819, and with it the distinction between the kauwā slave class and the makaʻāinana (commoners). The 1852 Constitution of the Kingdom of Hawaii officially made slavery illegal.

Before the arrival of European settlers, each Maori tribe () considered itself a separate entity equivalent to a nation. In traditional Maori society of Aotearoa, prisoners of war became taurekareka, slaves, unless released, ransomed or eaten. With some exceptions, the child of a slave remained a slave.

As far as it is possible to tell, slavery seems to have increased in the early 19th century with increased numbers of prisoners being taken by Māori military leaders, such as Hongi Hika and Te Rauparaha to satisfy the need for labor in the Musket Wars, to supply whalers and traders with food, flax and timber in return for western goods. The intertribal Musket Wars lasted 1807 to 1843 when large numbers of slaves were captured by northern tribes who had acquired muskets. About 20,000 Maori died in the wars which were concentrated in the North Island. An unknown number of slaves were captured. Northern tribes used slaves (called mokai) to grow large areas of potatoes for trade with visiting ships. Chiefs started an extensive sex trade in the Bay of Islands in the 1830s using mainly slave girls. By 1835 about 70-80 ships per year called into the port. One French captain described the impossibility of getting rid of the girls who swarmed over his ship outnumbering his crew of 70 by 3 to 1. All payments to the girls were stolen by the chief. By 1833 Christianity had become established in the north and large numbers of slaves were freed. However two Taranaki tribes, Ngati Tama and Ngati Mutunga, displaced by the wars carried out a carefully planned invasion of the Chatham Islands, 800 km east of Christchurch, in 1835. About 15% of the Polynesian Moriori natives who had migrated to the islands at about 1500 CE were killed, with many women being tortured to death. The remaining population was enslaved for the purpose of growing food, especially potatoes. The Moriori were treated in an inhumane and degrading manner for many years. Their culture was banned and they were forbidden to marry. Slavery was outlawed when the British entered into a constitutional arrangement with New Zealand in 1840 via the Treaty of Waitangi, although it did not end completely until government was effectively extended over the whole of the country with the defeat of the Kingi movement in the Wars of the mid-1860s.

Some Maori took Moriori partners. The state of enslavement of Moriori lasted until the 1860s although it had been discouraged by CMS missionaries in North New Zealand from the late 1820s. In 1870 Ngati Mutunga, one of the invading tribes, argued before the Native Land Court in New Zealand that their gross mistreatment of the Moriori was standard Maori practice or tikanga.

One group of Polynesians who migrated to the Chatham Islands became the Moriori who developed a largely pacifist culture. It was originally speculated that they settled the Chathams direct from Polynesia, but it is now widely believed they were disaffected Maori who emigrated from the South Island of New Zealand. Their pacifism left the Moriori unable to defend themselves when the islands were invaded by mainland Māori in the 1830s. Two Taranaki tribes, Ngati Tama and Ngati Mutunga, displaced by the musket wars, carried out a carefully planned invasion of the Chatham Islands, 800 km east of Christchurch, in 1835. About 15% of the Polynesian Moriori natives who had migrated to the islands at about 1500 CE were killed, with many women being tortured to death. The remaining population was enslaved for the purpose of growing food, especially potatoes. The Moriori were treated in an inhumane and degrading manner for many years. Their culture was banned and they were forbidden to marry. Slavery was outlawed when the British annexed New Zealand in 1840, immediately prior to the signing of the Treaty of Waitangi, although it did not end completely until government was effectively extended over the whole of the country with the defeat of the Kingi movement in the Wars of the mid-1860s.

Some 300 Moriori men, women and children were massacred and the remaining 1,200 to 1,300 survivors were enslaved.

Rapa Nui / Easter Island

The isolated island of Rapa Nui/ Easter Island was inhabited by the Rapanui, who suffered a series of slave raids from 1805 or earlier, culminating in a near genocidal experience in the 1860s. The 1805 raid was by American sealers and was one of a series that changed the attitude of the islanders to outside visitors, with reports in the 1820s and 1830s that all visitors received a hostile reception. In December 1862, Peruvian slave raiders took between 1,400 and 2,000 islanders back to Peru to work in the guano industry; this was about a third of the island's population and included much of the island's leadership, the last ariki-mau and possibly the last who could read Rongorongo. After intervention by the French ambassador in Lima, the last 15 survivors were returned to the island, but brought with them smallpox, which further devastated the island.

Slavery has existed, in one form or another, throughout the whole of human history. So, too, have movements to free large or distinct groups of slaves. However, abolitionism should be distinguished from efforts to help a particular group of slaves, or to restrict one practice, such as the slave trade.

Although there were numerous slave revolts in the Caribbean, the only successful uprising came in the French colony of Haiti in the 1790s, where the slaves rose up, killed the mulattoes and whites, and established the independent Republic of Haiti. Europe recoiled in horror.

Cyrus the Great, the founder of Persian Empire prohibited the systematic enslavement of conquered non-combatant population. Cyrus also freed slaves and allowed all deported peoples who were enslaved by preceding Assyrian and Babylonian kings, to return home. It is said that he freed up to 40,000 Jews and allowed them to return home. Cylinder of Cyrus the Great containing the Decree on the conquered non-combatant population.

In 1772, the Somersett Case (R. v. Knowles, ex parte Somersett) of the English Court of King's Bench ruled that it was unlawful for a slave to be forcibly taken abroad. The case has since been misrepresented as finding that slavery was unlawful in England (although not elsewhere in the British Empire). A similar case, that of Joseph Knight, took place in Scotland five years later and ruled slavery to be contrary to the law of Scotland.

Following the work of campaigners in the United Kingdom, such as William Wilberforce and Thomas Clarkson, the Act for the Abolition of the Slave Trade was passed by Parliament on 25 March 1807, coming into effect the following year. The act imposed a fine of £100 for every slave found aboard a British ship. The intention was to outlaw entirely the Atlantic slave trade within the whole British Empire.

The significance of the abolition of the British slave trade lay in the number of people hitherto sold and carried by British slave vessels. Britain shipped 2,532,300 Africans across the Atlantic, equalling 41% of the total transport of 6,132,900 individuals. This made the British empire the biggest slave-trade contributor in the world due to the magnitude of the empire, which made the abolition act all the more damaging to the global trade of slaves. Britain used its diplomatic influence to press other nations into treaties to ban their slave trade and to give the Royal Navy the right to interdict slave ships sailing under their national flag.

The Slavery Abolition Act, passed on 1 August 1833, outlawed slavery itself throughout the British Empire, with the exception of India. On 1 August 1834 slaves became indentured to their former owners in an apprenticeship system for six years. Full emancipation was granted ahead of schedule on 1 August 1838. Britain abolished slavery in both Hindu and Muslim India with the Indian Slavery Act, 1843.

Domestic slavery practised by the educated African coastal elites (as well as interior traditional rulers) in Sierra Leone was abolished in 1928. A study found practices of domestic slavery still widespread in rural areas in the 1970s.

There were slaves in mainland France (especially in trade ports such as Nantes or Bordeaux)., but the institution was never officially authorized there. The legal case of Jean Boucaux in 1739 clarified the unclear legal position of possible slaves in France, and was followed by laws that established registers for slaves in mainland France, who were limited to a three-year stay, for visits or learning a trade. Unregistered "slaves" in France were regarded as free. However, slavery was of vital importance in France's Caribbean possessions, especially Saint-Domingue.

In 1793, influenced by the French Declaration of the Rights of Man of August 1789 and alarmed as the massive slave revolt of August 1791 that had become the Haitian Revolution threatened to ally itself with the British, the French Revolutionary commissioners Sonthonax and Polverel declared general emancipation to reconcile them with France. In Paris, on 4 February 1794, Abbé Grégoire and the Convention ratified this action by officially abolishing slavery in all French territories outside mainland France, freeing all the slaves both for moral and security reasons.

Napoleon came to power in 1799 and soon had grandiose plans for the French sugar colonies; to achieve them he reintroduced slavery. Napoleon's major adventure into the Caribbean-sending 30,000 troops in 1802 to retake Saint Domingue (Haiti) from ex-slaves under Toussaint L'Ouverture who had revolted. Napoleon wanted to preserve France's financial benefits from the colony's sugar and coffee crops; he then planned to establish a major base at New Orleans. He therefore re-established slavery in Haiti and Guadeloupe, where it had been abolished after rebellions. Slaves and black freedmen fought the French for their freedom and independence. Revolutionary ideals played a central role in the fighting for it was the slaves and their allies who were fighting for the revolutionary ideals of freedom and equality, while the French troops under General Charles Leclerc fought to restore the order of the ancien régime. The goal of re-establishing slavery explicitly contradicted the ideals of the French Revolution. The French soldiers were unable to cope with the tropical diseases, and most died of yellow fever. Slavery was reimposed in Guadeloupe but not in Haiti, which became an independent black republic. Napoleon's vast colonial dreams for Egypt, India, the Caribbean, Louisiana, and even Australia were all doomed for lack of a fleet capable of matching Britain's Royal Navy. Realizing the fiasco Napoleon liquidated the Haiti project, brought home the survivors and sold off the huge Louisiana territory to the US in 1803.

In 1794 slavery was abolished in the French Empire. After seizing Lower Egypt in 1798, Napoleon Bonaparte issued a proclamation in Arabic, declaring all men to be free and equal. However, the French bought males as soldiers and females as concubines. Napoleon personally opposed the abolition and restored colonial slavery in 1802, a year after the capitulation of his troops in Egypt.

Victor Schœlcher and the 1848 abolition

The American Colonization Society, the primary vehicle for returning black Americans to greater freedom in Africa, established the colony of Liberia in 1821-23, on the premise that former American slaves would have greater freedom and equality there. The ACS assisted in the movement of thousands of African Americans to Liberia, with its founder Henry Clay stating; "unconquerable prejudice resulting from their color, they never could amalgamate with the free whites of this country. It was desirable, therefore, as it respected them, and the residue of the population of the country, to drain them off". Abraham Lincoln, an enthusiastic supporter of Clay, adopted his position on returning the blacks to their own land.

Slaves in the United States who escaped ownership would often make their way to Canada via the " Underground Railroad". The more famous of the African American abolitionists include former slaves Harriet Tubman, Sojourner Truth and Frederick Douglass. Many more people who opposed slavery and worked for abolition were northern whites, such as William Lloyd Garrison and John Brown. Slavery was legally abolished in 1865 by the Thirteenth Amendment to the United States Constitution.

While abolitionists agreed on the evils of slavery, there were differing opinions on what should happen after African Americans were freed. By the time of Emancipation, African-Americans were now native to the United States and did not want to leave. Most believed that their labor had made the land theirs as well as that of the whites.

The Declaration of the Powers, on the Abolition of the Slave Trade, of 8 February 1815 (Which also formed ACT, No. XV. of the Final Act of the Congress of Vienna of the same year) included in its first sentence the concept of the "principles of humanity and universal morality" as justification for ending a trade that was "odious in its continuance".

The 1926 Slavery Convention, an initiative of the League of Nations, was a turning point in banning global slavery. Article 4 of the Universal Declaration of Human Rights, adopted in 1948 by the UN General Assembly, explicitly banned slavery. The United Nations 1956 Supplementary Convention on the Abolition of Slavery was convened to outlaw and ban slavery worldwide, including child slavery. In December 1966, the UN General Assembly adopted the International Covenant on Civil and Political Rights, which was developed from the Universal Declaration of Human Rights. Article 4 of this international treaty bans slavery. The treaty came into force in March 1976 after it had been ratified by 35 nations.

As of November 2003, 104 nations had ratified the treaty. However, illegal forced labour involves millions of people in the 21st century, 43% for sexual exploitation and 32% for economic exploitation.

In May 2004, the 22 members of the Arab League adopted the Arab Charter on Human Rights, which incorporated the 1990 Cairo Declaration on Human Rights in Islam, which states:

Human beings are born free, and no one has the right to enslave, humiliate, oppress or exploit them, and there can be no subjugation but to God the Most-High.

-  Article 11, Cairo Declaration on Human Rights in Islam, 1990

Currently, the Anti-trafficking Coordination Team Initiative (ACT Team Initiative), a coordinated effort between the U.S. departments of justice, homeland security and labor, addresses human trafficking. The International Labour Organization estimates that there are 20.9 million victims of human trafficking globally, including 5.5 million children, of which 55% are women and girls.

The history of slavery originally was the history of the government's laws and policies toward slavery, and the political debates about it. Black history was promoted very largely at black colleges. The situation changed dramatically with the coming of the Civil Rights Movement of the 1950s. Attention shifted to the enslaved humans, the free blacks, and the struggles of the black community against adversity.

Peter Kolchin described the state of historiography in the early 20th century as follows:

During the first half of the twentieth century, a major component of this approach was often simply racism, manifest in the belief that blacks were, at best, imitative of whites. Thus Ulrich B. Phillips, the era's most celebrated and influential expert on slavery, combined a sophisticated portrait of the white planters' life and behavior with crude passing generalizations about the life and behavior of their black slaves.

Historians James Oliver Horton and Lois E. Horton described Phillips' mindset, methodology and influence:

His portrayal of blacks as passive, inferior people, whose African origins made them uncivilized, seemed to provide historical evidence for the theories of racial inferiority that supported racial segregation. Drawing evidence exclusively from plantation records, letters, southern newspapers, and other sources reflecting the slaveholder's point of view, Phillips depicted slave masters who provided for the welfare of their slaves and contended that true affection existed between master and slave.

Their account of the era rested, as one member of the Dunning school put it, on the assumption of "negro incapacity." Finding it impossible to believe that blacks could ever be independent actors on the stage of history, with their own aspirations and motivations, Dunning et al. portrayed African Americans either as "children", ignorant dupes manipulated by unscrupulous whites, or as savages, their primal passions unleashed by the end of slavery.

In the portrayal of the slave as a victim, the historian Stanley M. Elkins in his 1959 work Slavery: A Problem in American Institutional and Intellectual Life compared the effects of United States slavery to that resulting from the brutality of the Nazi concentration camps. He stated the institution destroyed the will of the slave, creating an "emasculated, docile Sambo" who identified totally with the owner. Elkins' thesis was challenged by historians. Gradually historians recognized that in addition to the effects of the owner-slave relationship, slaves did not live in a "totally closed environment but rather in one that permitted the emergence of enormous variety and allowed slaves to pursue important relationships with persons other than their master, including those to be found in their families, churches and communities."

Economic historians Robert W. Fogel and Stanley L. Engerman in the 1970s, through their work Time on the Cross, portrayed slaves as having internalized the Protestant work ethic of their owners. In portraying the more benign version of slavery, they also argue in their 1974 book that the material conditions under which the slaves lived and worked compared favorably to those of free workers in the agriculture and industry of the time. (This was also an argument of Southerners during the 19th century.)

In the 1970s and 1980s, historians made use of sources such as black music and statistical census data to create a more detailed and nuanced picture of slave life. Relying also on 19th-century autobiographies of ex-slaves (known as slave narratives) and the WPA Slave Narrative Collection, a set of interviews conducted with former slaves in the 1930s by the Federal Writers' Project, historians described slavery as the slaves remembered it. Far from slaves' being strictly victims or content, historians showed slaves as both resilient and autonomous in many of their activities. Despite their exercise of autonomy and their efforts to make a life within slavery, current historians recognize the precariousness of the slave's situation. Slave children quickly learned that they were subject to the direction of both their parents and their owners. They saw their parents disciplined just as they came to realize that they also could be physically or verbally abused by their owners. Historians writing during this era include John Blassingame ( Slave Community), Eugene Genovese ( Roll, Jordan, Roll), Leslie Howard Owens ( This Species of Property), and Herbert Gutman ( The Black Family in Slavery and Freedom).

Important work on slavery has continued; for instance, in 2003 Steven Hahn published the Pulitzer Prize-winning account, A Nation under Our Feet: Black Political Struggles in the Rural South from Slavery to the Great Migration, which examined how slaves built community and political understanding while enslaved, so they quickly began to form new associations and institutions when emancipated, including black churches separate from white control. In 2010, Robert E. Wright published a model that explains why slavery was more prevalent in some areas than others (e.g. southern than northern Delaware) and why some firms (individuals, corporations, plantation owners) chose slave labor while others used wage, indentured, or family labor instead.

Historical revisionism arrived when West Indian historian Eric Williams, a Marxist, in Capitalism and Slavery (1944), rejected this moral explanation and argued that abolition was now more profitable, for a century of sugarcane raising had exhausted the soil of the islands, and the plantations had become unprofitable. It was more profitable to sell the slaves to the government than to keep up operations. The 1807 prohibition of the international trade, Williams argued, prevented French expansion on other islands. Meanwhile, British investors turned to Asia, where labor was so plentiful that slavery was unnecessary. Williams went on to argue that slavery played a major role in making Britain prosperous. The high profits from the slave trade, he said, helped finance the Industrial Revolution. Britain enjoyed prosperity because of the capital gained from the unpaid work of slaves.

Since the 1970s numerous historians have challenged Williams from various angles and Gad Heuman has concluded, "More recent research has rejected this conclusion; it is now clear that the colonies of the British Caribbean profited considerably during the Revolutionary and Napoleonic Wars." In his major attack on the Williams's thesis, Seymour Drescher argues that Britain's abolition of the slave trade in 1807 resulted not from the diminishing value of slavery for Britain but instead from the moral outrage of the British voting public. Critics have also argued that slavery remained profitable in the 1830s because of innovations in agriculture so the profit motive was not central to abolition. Richardson (1998) finds Williams's claims regarding the Industrial Revolution are exaggerated, for profits from the slave trade amounted to less than 1% of domestic investment in Britain. Richardson further challenges claims (by African scholars) that the slave trade caused widespread depopulation and economic distress in Africa-indeed that it caused the "underdevelopment" of Africa. Admitting the horrible suffering of slaves, he notes that many Africans benefited directly because the first stage of the trade was always firmly in the hands of Africans. European slave ships waited at ports to purchase cargoes of people who were captured in the hinterland by African dealers and tribal leaders. Richardson finds that the "terms of trade" (how much the ship owners paid for the slave cargo) moved heavily in favor of the Africans after about 1750. That is, indigenous elites inside West and Central Africa made large and growing profits from slavery, thus increasing their wealth and power.

Economic historian Stanley Engerman finds that even without subtracting the associated costs of the slave trade (e.g., shipping costs, slave mortality, mortality of British people in Africa, defense costs) or reinvestment of profits back into the slave trade, the total profits from the slave trade and of West Indian plantations amounted to less than 5% of the British economy during any year of the Industrial Revolution. Engerman's 5% figure gives as much as possible in terms of benefit of the doubt to the Williams argument, not solely because it does not take into account the associated costs of the slave trade to Britain, but also because it carries the full-employment assumption from economics and holds the gross value of slave trade profits as a direct contribution to Britain's national income. Historian Richard Pares, in an article written before Williams's book, dismisses the influence of wealth generated from the West Indian plantations upon the financing of the Industrial Revolution, stating that whatever substantial flow of investment from West Indian profits into industry there was occurred after emancipation, not before.

The history of slavery spans many cultures, nationalities, and religions from ancient times to the present day. However the social, economic, and legal positions of slaves have differed vastly in different systems of slavery in different times and places. Slavery occurs relatively rarely among hunter-gatherer populations because it develops under conditions of social stratification.

The New York Slave Revolt of 1712 was an uprising in New York City, in the Province of New York, of 23 enslaved Africans. They killed nine whites and injured another six before they were stopped. More than three times that number of black people, 70, were arrested and jailed. Of these, 27 were put on trial, and 21 convicted and executed.

In the early 18th century, New York City had one of the largest slave populations of any of England's colonies. Slavery in the city differed from some of the other colonies because there were no large plantations. Slaves worked as domestic servants, artisans, dock workers, and various skilled laborers. Enslaved Africans lived near each other, making communication easy. They also often worked among free black people, a situation that did not exist on most Southern plantations. Slaves in the city could communicate and plan a conspiracy more easily than among those on plantations.

Events that presumably led to the revolt include a decrease in freedom and status when the English took over the colony in 1664. Under Dutch rule, when the city was part of New Netherland, freed slaves had certain legal rights, such as the rights to own land and to marry. After the English took over New Amsterdam and made it the colony of New York, they enacted laws that restricted the lives of enslaved peoples. A slave market was built near present-day Wall Street to accommodate the increase in slaves being imported by the Royal African Company.[citation needed ]

By the early 1700s, about 20 percent of the population were enslaved black people. The colonial government restricted this group through several measures: requiring slaves to carry a pass if traveling more than a mile (1.6 km) from home; discouraging marriage among them; prohibiting gatherings in groups of more than three persons; and requiring them to sit in separate galleries at church services.

A group of more than twenty black slaves gathered on the night of April 6, 1712, and set fire to a building on Maiden Lane near Broadway. While the white colonists tried to put out the fire, the enslaved blacks, armed with guns, hatchets, and swords, attacked the whites then ran off. Almost immediately all runaway slaves were captured and returned to their owners.

Colonial forces arrested seventy blacks and jailed them. Six are reported to have committed suicide. Twenty-seven were put on trial, 21 of whom were convicted and sentenced to death, including one woman with child. Twenty were burned to death and one was executed on a breaking wheel.[citation needed ]

After the revolt, the city and colony passed more restrictive laws governing black and Indian slaves. Slaves were not permitted to gather in groups of more than three, they were not permitted to carry firearms, and gambling was outlawed. Crimes of property damage, rape, and conspiracy to kill qualified for the death penalty. Free blacks were still allowed to own land, however. Anthony Portuguese (alternately spelled Portugies), owned land that makes up a portion of present-day Washington Square Park; this continued to be owned by his daughter and grandchildren.

The colony required slave owners who wanted to free their slaves to pay a tax of £200 per person, then an amount much higher than the cost of a slave. In 1715 Governor Robert Hunter argued in London before the Lords of Trade that manumission and the chance for a slave to inherit part of a master's wealth was important to maintain in New York. He said that this was a proper reward for a slave who had helped a master earn a lifetime's fortune, and that it could keep the slave from descending into despair.

The history of slavery spans many cultures, nationalities, and religions from ancient times to the present day. However the social, economic, and legal positions of slaves have differed vastly in different systems of slavery in different times and places.

Slavery occurs relatively rarely among hunter-gatherer populations because it develops under conditions of social stratification. Slavery operated in the very first civilizations (such as Sumer in Mesopotamia, which dates back as far as 3500 BCE). Slavery features in the Mesopotamian Code of Hammurabi (c. 1860 BCE), which refers to it as an established institution. Slavery became common within much of Europe during the Early Middle Ages and it continued into the following centuries. The Byzantine-Ottoman wars (1265-1479) and the Ottoman wars in Europe (14th to 20th centuries) resulted in the capture of large numbers of Christian slaves. The Dutch, French, Spanish, Portuguese, British, Arabs and a number of West African kingdoms played a prominent role in the Atlantic slave trade, especially after 1600. The Republic of Ragusa became the first European country to ban the slave trade in 1416. In modern times Denmark-Norway abolished the trade in 1802.

Although slavery is no longer legal anywhere in the world (with the exception of penal labour), human trafficking remains an international problem and an estimated 25-40 million people were enslaved as of 2013, the majority in Asia. During the 1983-2005 Second Sudanese Civil War people were taken into slavery. Evidence emerged in the late 1990s of systematic child-slavery and -trafficking on cacao plantations in West Africa. Slavery continues into the 21st century. Although Mauritania criminalized slavery in August 2007, an estimated up to 600,000 men, women and children, or 20% of the population of Mauritania, are currently enslaved, many of them used as bonded labor. Slavery in the 21st century continues, with the top ten countries with the highest prevalence according to the Global Slavery Index being North Korea, Eritrea, Burundi, the Central African Republic, Afghanistan, Mauritania, South Sudan, Pakistan, Cambodia and Iran. Islamist quasi-states such as the Islamic State of Iraq and the Levant and Boko Haram have abducted and enslaved women and children (often to serve as sex slaves).

Evidence of slavery predates written records, and has existed in many cultures. Mass slavery requires economic surpluses and a high population density to be viable. Due to these factors, the practice of slavery would have only proliferated after the invention of agriculture during the Neolithic Revolution, about 11,000 years ago.

French historian Fernand Braudel noted that slavery was endemic in Africa and part of the structure of everyday life. "Slavery came in different guises in different societies: there were court slaves, slaves incorporated into princely armies, domestic and household slaves, slaves working on the land, in industry, as couriers and intermediaries, even as traders". During the 16th century, Europe began to outpace the Arab world in the export traffic, with its slave traffic from Africa to the Americas. The Dutch imported slaves from Asia into their colony in South Africa. In 1807 Britain, which held extensive, although mainly coastal, colonial territories on the African continent (including southern Africa), made the international slave trade illegal, as did the United States in 1808.

Slavery in Ethiopia persisted until 1942. The Anti-Slavery Society estimated that there were 2,000,000 slaves in the early 1930s, out of an estimated population of between 8 and 16 million. It was finally abolished by order of emperor Haile Selassie on 26 August 1942.

When British rule was first imposed on the Sokoto Caliphate and the surrounding areas in northern Nigeria at the turn of the 20th century, approximately 2 million to 2.5 million people there were slaves. Slavery in northern Nigeria was finally outlawed in 1936.

Elikia M'bokolo, April 1998, Le Monde diplomatique. Quote: "The African continent was bled of its human resources via all possible routes. Across the Sahara, through the Red Sea, from the Indian Ocean ports and across the Atlantic. At least ten centuries of slavery for the benefit of the Muslim countries (from the ninth to the nineteenth)." He continues: "Four million slaves exported via the Red Sea, another four million through the Swahili ports of the Indian Ocean, perhaps as many as nine million along the trans-Saharan caravan route, and eleven to twenty million (depending on the author) across the Atlantic Ocean"

Zanzibar was once East Africa's main slave-trading port, and under Omani Arabs in the 19th century, as many as 50,000 slaves were passing through the city each year.

Prior to the 16th century, the bulk of slaves exported from Africa were shipped from East Africa to the Arabian peninsula. Zanzibar became a leading port in this trade. Arab slave traders differed from European ones in that they would often conduct raiding expeditions themselves, sometimes penetrating deep into the continent. They also differed in that their market greatly preferred the purchase of female slaves over male ones.

The increased presence of European rivals along the East coast led Arab traders to concentrate on the overland slave caravan routes across the Sahara from the Sahel to North Africa. The German explorer Gustav Nachtigal reported seeing slave caravans departing from Kukawa in Bornu bound for Tripoli and Egypt in 1870. The slave trade represented the major source of revenue for the state of Bornu as late as 1898. The eastern regions of the Central African Republic have never recovered demographically from the impact of 19th-century raids from the Sudan and still have a population density of less than 1 person/km². During the 1870s, European initiatives against the slave trade caused an economic crisis in northern Sudan, precipitating the rise of Mahdist forces. Mahdi's victory created an Islamic state, one that quickly reinstituted slavery.

The Middle Passage, the crossing of the Atlantic to the Americas, endured by slaves laid out in rows in the holds of ships, was only one element of the well-known triangular trade engaged in by Portuguese, Dutch, Danish-Norwegians, French, British and others. Ships having landed slaves in Caribbean ports would take on sugar, indigo, raw cotton, and later coffee, and make for Liverpool, Nantes, Lisbon or Amsterdam. Ships leaving European ports for West Africa would carry printed cotton textiles, some originally from India, copper utensils and bangles, pewter plates and pots, iron bars more valued than gold, hats, trinkets, gunpowder and firearms and alcohol. Tropical shipworms were eliminated in the cold Atlantic waters, and at each unloading, a profit was made.

While talking about the slave trade in East Africa in his journals, "To overdraw its evil is a simple impossibility."

To overdraw its evil is a simple impossibility.

David Livingstone while travelling in the African Great Lakes Region in 1866 described a trail of slaves as such:

19th June 1866 - We passed a woman tied by the neck to a tree and dead, the people of the country explained that she had been unable to keep up with the other slaves in a gang, and her master had determined that she should not become anyone's property if she recovered.
26th June. - ...We passed a slave woman shot or stabbed through the body and lying on the path: a group of men stood about a hundred yards off on one side, and another of the women on the other side, looking on; they said an Arab who passed early that morning had done it in anger at losing the price he had given for her, because she was unable to walk any longer.
27th June 1866 - To-day we came upon a man dead from starvation, as he was very thin. One of our men wandered and found many slaves with slave-sticks on, abandoned by their masters from want of food; they were too weak to be able to speak or say where they had come from; some were quite young.

The strangest disease I have seen in this country seems really to be broken-heartedness, and it attacks free men who have been captured and made slaves... Twenty one were unchained, as now safe; however all ran away at once; but eight with many others still in chains, died in three days after the crossing. They described their only pain in the heart, and placed the hand correctly on the spot, though many think the organ stands high up in the breast-bone.

African states played a role in the slave trade, and slavery was a common practice among Sub Saharan Africans before the involvement of the Arabs, Berbers and Europeans. There were three types: those who were slaves through conquest, those who were slaves due to unpaid debts, or those whose parents gave them as slaves to tribal chiefs. Chieftains would barter their slaves to Arab, Berber, Ottoman or European buyers for rum, spices, cloth or other goods. Selling captives or prisoners was commonly practiced among Africans, Turks, Berbers and Arabs during that era. However, as the Atlantic slave trade increased its demand, local systems which primarily serviced indentured servitude expanded. European slave trading, as a result, was the most pivotal change in the social, economic, cultural, spiritual, religious, political dynamics of the concept of slave trading. It ultimately undermined local economies and political stability as villages' vital labour forces were shipped overseas as slave raids and civil wars became commonplace. Crimes which were previously punishable by some other means became punishable by enslavement.

The kings of Dahomey sold their war captives into transatlantic slavery, who otherwise may have been killed in a ceremony known as the Annual Customs. As one of West Africa's principal slave states, Dahomey became extremely unpopular with neighbouring peoples. Like the Bambara Empire to the east, the Khasso kingdoms depended heavily on the slave trade for their economy. A family's status was indicated by the number of slaves it owned, leading to wars for the sole purpose of taking more captives. This trade led the Khasso into increasing contact with the European settlements of Africa's west coast, particularly the French. Benin grew increasingly rich during the 16th and 17th centuries on the slave trade with Europe; slaves from enemy states of the interior were sold, and carried to the Americas in Dutch and Portuguese ships. The Bight of Benin's shore soon came to be known as the "Slave Coast".

The slave trade is the ruling principle of my people. It is the source and the glory of their wealth...the mother lulls the child to sleep with notes of triumph over an enemy reduced to slavery...

In 1807, under internal and external pressures, the United Kingdom made illegal the international trade in slaves. The Royal Navy was deployed to prevent slavers from the United States, France, Spain, Portugal, Holland, West Africa and Arabia. The King of Bonny (now in Nigeria) allegedly became dissatisfied of the British intervention in stopping slave trading.

We think this trade must go on. That is the verdict of our oracle and the priests. They say that your country, however great, can never stop a trade ordained by God himself.

Joseph Miller states that African buyers would prefer males, but in reality, women and children would be more easily captured as men fled. Those captured would be sold for various reasons such as food, debts, or servitude. Once captured, the journey to the coast killed many and weakened others. Disease engulfed many, and insufficient food damaged those who made it to the coasts. Scurvy was so common that it was known as mal de Luanda (Luanda sickness). The assumption for those who died on the journey died from malnutrition. As food was limited, water may have been just as bad. Dysentery was widespread and poor sanitary conditions at ports did not help. Since supplies were poor, slaves were not equipped with the best clothing that further exposed to more diseases.

If the fear of disease caused terror, the psyche of slaves for being captured was just as terrifying. The most popular assumption for being captured was Europeans were cannibals. Stories and rumours spread that whites captured Africans to eat them. Olaudah Equiano accounts his experience about the sorrow slaves encountered at the ports. He talks about his first moment on a slave ship and asked if he was going to be eaten. Yet, the worst for slaves has only begun, and the journey on the water proved to be more terrifying. For every 100 Africans captured, only 64 would reach the coast, and only about 50 would reach the New World.

Others believe that slavers had a vested interest in capturing rather than killing, and in keeping their captives alive; and that this coupled with the disproportionate removal of males and the introduction of new crops from the Americas ( cassava, maize) would have limited general population decline to particular regions of western Africa around 1760-1810, and in Mozambique and neighbouring areas half a century later. There has also been speculation that within Africa, females were most often captured as brides, with their male protectors being a "bycatch" who would have been killed if there had not been an export market for them.

British explorer Mungo Park encountered a group of slaves when traveling through Mandinka country:

They were all very inquisitive, but they viewed me at first with looks of horror, and repeatedly asked if my countrymen were cannibals. They were very desirous to know what became of the slaves after they had crossed the salt water. I told them that they were employed in cultivation the land; but they would not believe me ... A deeply-rooted idea that the whites purchase negroes for the purpose of devouring them, or of selling them to others that they may be devoured hereafter, naturally makes the slaves contemplate a journey towards the coast with great terror, insomuch that the slatees are forced to keep them constantly in irons, and watch them very closely, to prevent their escape.

During the period from the late 19th century and early 20th century, demand for the labour-intensive harvesting of rubber drove frontier expansion and forced labour. The personal monarchy of Belgian King Leopold II in the Congo Free State saw mass killings and slavery to extract rubber.

Stephanie Smallwood in her book Saltwater Slavery uses Equiano's account on board ships to describe the general thoughts of most slaves.

Then," said I, "how comes it in all our country we never heard of them?" They told me because they lived so very far off. I then asked where were their women? Had they any like themselves? I was told that they had. "And why," said I, "do we not see them?" They answered, because they were left behind. I asked how the vessel could go? They told me they could not tell; but that there was cloth put upon the masts by the help of the ropes I saw, and then the vessel went on; and the white men had some spell or magic they put in the water when they liked, in order to stop the vessel. I was exceedingly amazed at this account, and really thought they were spirits. I there-fore wished much to be from amongst them, for I expected they would sacrifice me; but my wishes were vain-for we were so quartered that it was impossible for any of us to make our escape.

Accounts like these raised many questions as some slaves grew philosophical with their journey. Smallwood points out the challenges for slaves were physical and metaphysical. The physical would be obvious as the challenge to overcome capacity, lack of ship room, and food. The metaphysical was unique as the open sea would challenge African slaves' vision of the ocean as habitable. At essence, the journey on the ocean would prove to be an African's biggest fear that would keep them in awe. Combining this with the lack of knowledge of the sea, Africans would be entering a world of anxiety never seen before. Yet, Europeans were also fearful of the sea, but not to the extent of Africans. One of these dilemmas came with the sense of time. Africans used seasonal weather to predict time and days. The moon was a sense of time, but used like in other cultures. On the sea, Africans used the moon to best count the days, but the sea did not provide seasonal changes for them to know how long they were at sea. Counting the days on a ship was not the main priority, however. Surviving the voyage was the main horror. No one escaped diseases as the close quarters infected everyone including the crew. Death was so common that ships were called tumbeiros or floating tombs. What shocked Africans the most was how death was handled in the ships. Smallwood says the traditions for an African death was delicate and community-based. On ships, bodies would be thrown into the sea. Because the sea represented bad omens, bodies in the sea represented a form of purgatory and the ship a form of hell. In the end, the Africans who made the journey would have survived disease, malnutrition, confined space, close death, and the trauma of the ship.

In Algiers during the time of the Regency of Algiers in North Africa in the 19th century, 1.5 million Christians and Europeans were captured and forced into slavery. This eventually led to the Bombardment of Algiers in 1816 by the British and Dutch, forcing the Dey of Algiers to free many slaves.

The trading of children has been reported in modern Nigeria and Benin. In parts of Ghana, a family may be punished for an offense by having to turn over a virgin female to serve as a sex slave within the offended family. In this instance, the woman does not gain the title or status of "wife". In parts of Ghana, Togo, and Benin, shrine slavery persists, despite being illegal in Ghana since 1998. In this system of ritual servitude, sometimes called trokosi (in Ghana) or voodoosi in Togo and Benin, young virgin girls are given as slaves to traditional shrines and are used sexually by the priests in addition to providing free labor for the shrine.

An article in the Middle East Quarterly in 1999 reported that slavery is endemic in Sudan. Estimates of abductions during the Second Sudanese Civil War range from 14,000 to 200,000 people.

During the Second Sudanese Civil War people were taken into slavery; estimates of abductions range from 14,000 to 200,000. Abduction of Dinka women and children was common. In Mauritania it is estimated that up to 600,000 men, women and children, or 20% of the population, are currently enslaved, many of them used as bonded labor. Slavery in Mauritania was criminalized in August 2007.

During the Darfur conflict that began in 2003, many people were kidnapped by Janjaweed and sold into slavery as agricultural labor, domestic servants and sex slaves.

In Niger, slavery is also a current phenomenon. A Nigerien study has found that more than 800,000 people are enslaved, almost 8% of the population. Niger installed an anti-slavery provision in 2003. In a landmark ruling in 2008, the ECOWAS Community Court of Justice declared that the Republic of Niger failed to protect Hadijatou Mani Koraou from slavery, and awarded Mani CFA 10,000,000 (approximately US$20,000) in reparations.

Sexual slavery and forced labor are common in the Democratic Republic of Congo.

Many pygmies in the Republic of Congo and Democratic Republic of Congo belong from birth to Bantus in a system of slavery.

Evidence emerged in the late 1990s of systematic slavery in cacao plantations in West Africa; see the chocolate and slavery article.

On the night of 14-15 April 2014, a group of militants attacked the Government Girls Secondary School in Chibok, Nigeria. They broke into the school, pretending to be guards, telling the girls to get out and come with them. A large number of students were taken away in trucks, possibly into the Konduga area of the Sambisa Forest where Boko Haram were known to have fortified camps. Houses in Chibok were also burned down in the incident. According to police, approximately 276 children were taken in the attack, of whom 53 had escaped as of 2 May. Other reports said that 329 girls were kidnapped, 53 had escaped and 276 were still missing. The students have been forced to convert to Islam and into marriage with members of Boko Haram, with a reputed " bride price" of ₦2,000 each ($12.50/ £7.50). Many of the students were taken to the neighbouring countries of Chad and Cameroon, with sightings reported of the students crossing borders with the militants, and sightings of the students by villagers living in the Sambisa Forest, which is considered a refuge for Boko Haram.

On 5 May 2014 a video in which Boko Haram leader Abubakar Shekau claimed responsibility for the kidnappings emerged. Shekau claimed that "Allah instructed me to sell them...I will carry out his instructions" and "[s]lavery is allowed in my religion, and I shall capture people and make them slaves." He said the girls should not have been in school and instead should have been married since girls as young as nine are suitable for marriage.

During the Second Libyan Civil War Libyans started capturing some of the Sub-Saharan African migrants trying to get to Europe through Libya and selling them on slave markets. Slaves are often ransomed to their families and in the meantime until ransom can be paid, they may be tortured, forced to work, sometimes worked to death, and eventually they may be executed or left to starve if the payment has not been made after a period of time. Women are often raped and used as sex slaves and sold to brothels.

Many child migrants also suffer from abuse and child rape in Libya.

In Pre-Columbian Mesoamerica the most common forms of slavery were those of prisoners of war and debtors. People unable to pay back debts could be sentenced to work as slaves to the persons owed until the debts were worked off. Warfare was important to Maya society, because raids on surrounding areas provided the victims required for human sacrifice, as well as slaves for the construction of temples. Most victims of human sacrifice were prisoners of war or slaves. Slavery was not usually hereditary; children of slaves were born free. In the Inca Empire, workers were subject to a in lieu of taxes which they paid by working for the government. Each , or extended family, would decide which family member to send to do the work. It is unclear if this labor draft or corvée counts as slavery. The Spanish adopted this system, particularly for their silver mines in Bolivia.

Other slave-owning societies and tribes of the New World were, for example, the Tehuelche of Patagonia, the Comanche of Texas, the Caribs of Dominica, the Tupinambá of Brazil, the fishing societies, such as the Yurok, that lived along the coast from what is now Alaska to California, the Pawnee and Klamath. Many of the indigenous peoples of the Pacific Northwest Coast, such as the Haida and Tlingit, were traditionally known as fierce warriors and slave-traders, raiding as far as California. Slavery was hereditary, the slaves being prisoners of war. Among some Pacific Northwest tribes about a quarter of the population were slaves. One slave narrative was composed by an Englishman, John R. Jewitt, who had been taken alive when his ship was captured in 1802; his memoir provides a detailed look at life as a slave, and asserts that a large number were held.

During the period from the late 19th century and early 20th century, demand for the labor-intensive harvesting of rubber drove frontier expansion and slavery in Latin America and elsewhere. Indigenous peoples were enslaved as part of the rubber boom in Ecuador, Peru, Colombia, and Brazil. In Central America, rubber tappers participated in the enslavement of the indigenous Guatuso-Maleku people for domestic service.

Slavery was a mainstay of the Brazilian colonial economy, especially in mining and sugarcane production. 35.3% of all slaves involved in the Atlantic Slave trade went to Brazil. 4 million slaves were obtained by Brazil, 1.5 million more than any other country. Starting around 1550, the Portuguese began to trade African slaves to work the sugar plantations, once the native Tupi people deteriorated. Although Portuguese Prime Minister Sebastião José de Carvalho e Melo, 1st Marquis of Pombal abolished slavery in mainland Portugal on 12 February 1761, slavery continued in her overseas colonies. Slavery was practiced among all classes. Slaves were owned by upper and middle classes, by the poor, and even by other slaves.

From São Paulo, the Bandeirantes, adventurers mostly of mixed Portuguese and native ancestry, penetrated steadily westward in their search for Indian slaves. Along the Amazon river and its major tributaries, repeated slaving raids and punitive attacks left their mark. One French traveler in the 1740s described hundreds of miles of river banks with no sign of human life and once-thriving villages that were devastated and empty. In some areas of the Amazon Basin, and particularly among the Guarani of southern Brazil and Paraguay, the Jesuits had organized their Jesuit Reductions along military lines to fight the slavers. In the mid-to-late 19th century, many Amerindians were enslaved to work on rubber plantations.

Escaped slaves formed Maroon communities which played an important role in the histories of Brazil and other countries such as Suriname, Puerto Rico, Cuba, and Jamaica. In Brazil, the Maroon villages were called palenques or quilombos. Maroons survived by growing vegetables and hunting. They also raided plantations. At these attacks, the maroons would burn crops, steal livestock and tools, kill slavemasters, and invite other slaves to join their communities.

Jean-Baptiste Debret, a French painter who was active in Brazil in the first decades of the 19th century, started out with painting portraits of members of the Brazilian Imperial family, but soon became concerned with the slavery of both blacks and indigenous inhabitants. His paintings on the subject (two appear on this page) helped bring attention to the subject in both Europe and Brazil itself.

The Clapham Sect, a group of evangelical reformers, campaigned during much of the 19th century for Britain to use its influence and power to stop the traffic of slaves to Brazil. Besides moral qualms, the low cost of slave-produced Brazilian sugar meant that British colonies in the West Indies were unable to match the market prices of Brazilian sugar, and each Briton was consuming 16 pounds (7 kg) of sugar a year by the 19th century. This combination led to intensive pressure from the British government for Brazil to end this practice, which it did by steps over several decades.

Brazil's 1877-78 Grande Seca (Great Drought) in the cotton-growing northeast led to major turmoil, starvation, poverty and internal migration. As wealthy plantation holders rushed to sell their slaves south, popular resistance and resentment grew, inspiring numerous emancipation societies. They succeeded in banning slavery altogether in the province of Ceará by 1884. Slavery was legally ended nationwide on 13 May by the ("Golden Law") of 1888. It was an institution in decadence at these times, as since the 1880s the country had begun to use European immigrant labor instead. Brazil was the last nation in the Western Hemisphere to abolish slavery.

Slavery was commonly used in the parts of the Caribbean controlled by France and the British Empire. The Lesser Antilles islands of Barbados, St. Kitts, Antigua, Martinique and Guadeloupe, which were the first important slave societies of the Caribbean, began the widespread use of African slaves by the end of the 17th century, as their economies converted from sugar production.

England had multiple sugar islands in the Caribbean, especially Jamaica, Barbados, Nevis, and Antigua, which provided a steady flow of sugar sales; slave labor produced the sugar. By the 1700s, there were more slaves in Barbados than all the colonies combined. Since Barbados did not have many mountains, the British were able to clear land for sugar cane. Indentured servants were initially sent to Barbados to work in the sugar fields. These indentured servants were treated so poorly that future indentured servants stopped going to Barbados, and there were not enough people to work the fields. This is when the British started bringing in African slaves. It was important for the slaves to be in Barbados because sugar had become a necessity for most people and the demand for it was high.

An important result of Britain's victory in the War of the Spanish Succession (1702-1714) was enlarging its role in the slave trade. Of special importance was the successful secret negotiation with France to obtain thirty-year monopoly on the Spanish slave trade, called the Queen Anne of Great Britain also allowed her North American colonies like Virginia to make laws that promoted black slavery. Anne had secretly negotiated with France to get its approval regarding the Asiento. She boasted to Parliament of her success in taking the Asiento away from France and London celebrated her economic coup. Most of the slave trade involved sales to Spanish colonies in the Caribbean, and to Mexico, as well as sales to British colonies in the Caribbean and in North America. Historian Vinita Ricks says the agreement allotted Queen Anne "22.5% (and King Philip V, of Spain 28%) of all profits collected for her personal fortune." Ricks concludes that the Queen's "connection to slave trade revenue meant that she was no longer a neutral observer. She had a vested interest in what happened on slave ships."

By 1778, the French were importing approximately 13,000 Africans for enslavement yearly to the French West Indies.

To regularise slavery, in 1685 Louis XIV had enacted the , which accorded certain human rights to slaves and responsibilities to the master, who was obliged to feed, clothe and provide for the general well-being of his slaves. Free blacks owned one-third of the plantation property and one-quarter of the slaves in Saint Domingue (later Haiti). Slavery in the French First Republic was abolished on 4 February 1794. When it became clear that Napoleon intended to re-establish slavery in Haiti, Dessalines and Pétion switched sides, in October 1802. On 1 January 1804, Jean-Jacques Dessalines, the new leader under the dictatorial 1801 constitution, declared Haiti a free republic. Thus Haiti became the second independent nation in the Western Hemisphere, after the United States, and the only successful slave rebellion in world history.

Whitehall in England announced in 1833 that slaves in its territories would be totally freed by 1840. In the meantime, the government told slaves they had to remain on their plantations and would have the status of "apprentices" for the next six years.

In Port-of-Spain, Trinidad, on 1 August 1834, an unarmed group of mainly elderly Negroes being addressed by the Governor at Government House about the new laws, began chanting: "Pas de six ans. Point de six ans" ("Not six years. No six years"), drowning out the voice of the Governor. Peaceful protests continued until a resolution to abolish apprenticeship was passed and de facto freedom was achieved. Full emancipation for all was legally granted ahead of schedule on 1 August 1838, making Trinidad the first British colony with slaves to completely abolish slavery.

In late August 1619, the frigate , a privateer ship owned by Robert Rich, 2nd Earl of Warwick, but flying a Dutch flag arrived at Point Comfort, Virginia (several miles downstream from the colony of Jamestown, Virginia) with the first recorded slaves from Africa to Virginia. The approximately 20 Africans were from the present-day Angola. They had been removed by the White Lion's crew from a Portuguese slave ship, the São João Bautista.

Only a fraction of the enslaved Africans brought to the New World came to British North America, perhaps as little as 5% of the total. The vast majority of slaves were sent to the Caribbean sugar colonies, Brazil, or Spanish America.

By the 1680s, with the consolidation of England's Royal African Company, enslaved Africans were arriving in English colonies in larger numbers, and the institution continued to be protected by the British government. Colonists now began purchasing slaves in larger numbers.

1640: Virginia courts sentence John Punch to lifetime slavery, marking the earliest legal sanctioning of slavery in English colonies.

1641: Massachusetts legalizes slavery.

1650: Connecticut legalizes slavery.

1654: Virginia sanctions "the right of Negros to own slaves of their own race" after African Anthony Johnson, former indentured servant, sued to have fellow African John Casor declared not an indentured servant but "slave for life."

1661: Virginia officially recognizes slavery by statute.

1662: A Virginia statute declares that children born would have the same status as their mother.

1663: Maryland legalizes slavery.

1664: Slavery is legalized in New York and New Jersey.

1670: Carolina (later, South Carolina and North Carolina) is founded mainly by planters from the overpopulated British sugar island colony of Barbados, who brought relatively large numbers of African slaves from that island.

The shift from indentured servants to African slaves was prompted by a dwindling class of former servants who had worked through the terms of their indentures and thus became competitors to their former masters. These newly freed servants were rarely able to support themselves comfortably, and the tobacco industry was increasingly dominated by large planters. This caused domestic unrest culminating in Bacon's Rebellion. Eventually, chattel slavery became the norm in regions dominated by plantations.

Several local slave rebellions took place during the 17th and 18th centuries: Gloucester County, Virginia Revolt (1663); New York Slave Revolt of 1712; Stono Rebellion (1739); and New York Slave Insurrection of 1741.

Within the British Empire, the Massachusetts courts began to follow England when, in 1772, England became the first country in the world to outlaw the slave trade within its borders (see Somerset v Stewart) followed by the Knight v. Wedderburn decision in Scotland in 1778. Between 1764 and 1774, seventeen slaves appeared in Massachusetts courts to sue their owners for freedom. In 1766, John Adams' colleague Benjamin Kent won the first trial in the present-day United States to free a slave (Slew vs. Whipple).

The Republic of Vermont banned slavery in its constitution of 1777 and continued the ban when it entered the United States in 1791. Through the Northwest Ordinance of 1787 under the Congress of the Confederation, slavery was prohibited in the territories north west of the Ohio River. By 1804, abolitionists succeeded in passing legislation that ended legal slavery in every northern state (with slaves above a certain age legally transformed to indentured servants). Congress banned the international importation or export of slaves on 1 January 1808; but not the internal slave trade.

Despite the actions of abolitionists, free blacks were subject to racial segregation in the Northern states. While England did not ban slavery in present-day Canada until 1833, free blacks found refugee and liberty there after the America Revolution and again after the War of 1812. Slavery in Canada was largely ended by judicial court decisions by the early nineteenth century. Refugees from slavery fled the South across the Ohio River to the North via the Underground Railroad. Midwestern state governments asserted States Rights arguments to refuse federal jurisdiction over fugitives. Some juries exercised their right of jury nullification and refused to convict those indicted under the Fugitive Slave Act of 1850.

After the passage of the Kansas-Nebraska Act in 1854, armed conflict broke out in Kansas Territory, where the question of whether it would be admitted to the Union as a slave state or a free state had been left to the inhabitants. The radical abolitionist John Brown was active in the mayhem and killing in " Bleeding Kansas." The true turning point in public opinion is better fixed at the Lecompton Constitution fraud. Pro-slavery elements in Kansas had arrived first from Missouri and quickly organized a territorial government that excluded abolitionists. Through the machinery of the territory and violence, the pro-slavery faction attempted to force an unpopular pro-slavery constitution through the state. This infuriated Northern Democrats, who supported popular sovereignty, and was exacerbated by the Buchanan administration reneging on a promise to submit the constitution to a referendum-which would surely fail. Anti-slavery legislators took office under the banner of the newly formed Republican Party. The Supreme Court in the Dred Scott decision of 1857 asserted that one could take one's property anywhere, even if one's property was chattel and one crossed into a free territory. It also asserted that African Americans could not be federal citizens. Outraged critics across the North denounced these episodes as the latest of the Slave Power (the politically organized slave owners) taking more control of the nation.

The slave population in the United States stood at four million. Ninety-five percent of blacks lived in the South, comprising one third of the population there as opposed to 1% of the population of the North. The central issue in politics in the 1850s involved the extension of slavery into the western territories, which settlers from the Northern states opposed. The Whig Party split and collapsed on the slavery issue, to be replaced in the North by the new Republican Party, which was dedicated to stopping the expansion of slavery. Republicans gained a majority in every northern state by absorbing a faction of anti-slavery Democrats, and warning that slavery was a backward system that undercut democracy and economic modernization. Numerous compromise proposals were put forward, but they all collapsed. A majority of Northern voters were committed to stopping the expansion of slavery, which they believed would ultimately end slavery. Southern voters were overwhelmingly angry that they were being treated as second-class citizens. In the election of 1860, the Republicans swept Abraham Lincoln into the Presidency and his party took control (with only 39.8% of the popular vote) and legislators into Congress. The states of the deep South, convinced that the economic power of what they called " King Cotton" would overwhelm the North and win support from Europe voted to seceded from the U.S. (the Union). They formed the Confederate States of America, based on the promise of maintaining slavery. War broke out in April 1861, as both sides sought wave after wave of enthusiasm among young men volunteering to form new regiments and new armies. In the North, the main goal was to preserve the union as an expression of American nationalism.

By 1862 most northern leaders realized that the mainstay of Southern secession, slavery, had to be attacked head-on. All the border states rejected President Lincoln's proposal for compensated emancipation. However, by 1865 all had begun the abolition of slavery, except Kentucky and Delaware. The Emancipation Proclamation was an executive order issued by Lincoln on 1 January 1863. In a single stroke, it changed the legal status, as recognized by the U.S. government, of 3 million slaves in designated areas of the Confederacy from "slave" to "free." It had the practical effect that as soon as a slave escaped the control of the Confederate government, by running away or through advances of federal troops, the slave became legally and actually free. Plantation owners, realizing that emancipation would destroy their economic system, sometimes moved their slaves as far as possible out of reach of the Union army. By June 1865, the Union Army controlled all of the Confederacy and liberated all of the designated slaves. The owners were never compensated. Over 200,000 free blacks and newly freed slaves fought for the Union in the Army and Navy, thereby validating their claims to full citizenship.

The severe dislocations of war and Reconstruction had a severe negative impact on the black population, with a large amount of sickness and death. After liberation, many of the Freedmen remained on the same plantation. Others fled or crowded into refugee camps operated by the Freedmen's Bureau. The Bureau provided food, housing, clothing, medical care, church services, some schooling, legal support, and arranged for labor contracts. Fierce debates about the rights of the Freedmen, and of the defeated Confederates, often accompanied by killings of black leaders, marked the Reconstruction Era, 1863-77.

Slavery was never reestablished, but after 1877, white Democrats took control of all the southern states and blacks lost nearly all the political power they had achieved during Reconstruction. By 1900 they also lost the right to vote. They had become second class citizens. The great majority lived in the rural South in poverty working as laborers, sharecroppers or tenant farmers; a small proportion owned their own land. The black churches, especially the Baptist Church, was the center of community activity and leadership.

Slavery in the Middle East first developed out of the slavery practices of the Ancient Near East, and these practices were radically different at times, depending on social-political factors such as the Arab slave trade. Two rough estimates by scholars of the number of slaves held over twelve centuries in Muslim lands are 11.5 million and 14 million.

Under Sharia (Islamic law), children of slaves or prisoners of war could become slaves but only non-Muslims. Manumission of a slave was encouraged as a way of expiating sins. Many early converts to Islam, such as Bilal ibn Rabah al-Habashi, were the poor and former slaves. In theory, slavery in Islamic law does not have a racial or color component, although this has not always been the case in practice.

Bernard Lewis writes: "In one of the sad paradoxes of human history, it was the humanitarian reforms brought by Islam that resulted in a vast development of the slave trade inside, and still more outside, the Islamic empire." He notes that the Islamic injunctions against the enslavement of Muslims led to massive importation of slaves from the outside. According to Patrick Manning, Islam by recognizing and codifying the slavery seems to have done more to protect and expand slavery than the reverse.

Slavery was a legal and important part of the economy of the Ottoman Empire and Ottoman society until the slavery of Caucasians was banned in the early 19th century, although slaves from other groups were allowed. In Constantinople (present-day Istanbul), the administrative and political center of the Empire, about a fifth of the population consisted of slaves in 1609. Even after several measures to ban slavery in the late 19th century, the practice continued largely unfazed into the early 20th century. As late as 1908, female slaves were still sold in the Ottoman Empire. Sexual slavery was a central part of the Ottoman slave system throughout the history of the institution.

A member of the Ottoman slave class, called a in Turkish, could achieve high status. Harem guards and janissaries are some of the better-known positions a slave could hold, but slaves were actually often at the forefront of Ottoman politics. The majority of officials in the Ottoman government were bought slaves, raised free, and integral to the success of the Ottoman Empire from the 14th century into the 19th. Many officials themselves owned a large number of slaves, although the Sultan himself owned by far the largest amount. By raising and specially training slaves as officials in palace schools such as Enderun, the Ottomans created administrators with intricate knowledge of government and fanatic loyalty.

Ottomans practiced , a sort of "blood tax" or "child collection", young Christian boys from the Balkans and Anatolia were taken from their homes and families, brought up as Muslims, and enlisted into the most famous branch of the , the Janissaries, a special soldier class of the Ottoman army that became a decisive faction in the Ottoman invasions of Europe.

During the various 18th and 19th century persecution campaigns against Christians as well as during the culminating Assyrian, Armenian and Greek genocides of World War I, many indigenous Armenian, Assyrian and Greek Christian women and children were carried off as slaves by the Ottoman Turks and their Kurdish allies. Henry Morgenthau, Sr., U.S. Ambassador in Constantinople from 1913 to 1916, reports in his Ambassador Morgenthau's Story that there were gangs trading white slaves during his term in Constantinople. He also reports that Armenian girls were sold as slaves during the Armenian Genocide.

The Arab or Islamic slave trade lasted much longer than the Atlantic or European slave trade: "It began in the middle of the seventh century and survives today in Mauritania and Sudan. With the Islamic slave trade, we're talking of 14 centuries rather than four." Further, "whereas the gender ratio of slaves in the Atlantic trade was two males to every female, in the Islamic trade, it was two females to every male," according to Ronald Segal

According to media reports from late 2014 the Islamic State of Iraq and the Levant (ISIL) was selling Yazidi and Christian women as slaves. According to Haleh Esfandiari of the Woodrow Wilson International Center for Scholars, after ISIL militants have captured an area "[t]hey usually take the older women to a makeshift slave market and try to sell them." In mid-October 2014, the UN estimated that 5,000 to 7,000 Yazidi women and children were abducted by ISIL and sold into slavery. In the digital magazine , ISIL claimed religious justification for enslaving Yazidi women whom they consider to be from a heretical sect. ISIL claimed that the Yazidi are idol worshipers and their enslavement is part of the old shariah practice of spoils of war. According to The Wall Street Journal, ISIL appeals to apocalyptic beliefs and claims "justification by a Hadith that they interpret as portraying the revival of slavery as a precursor to the end of the world".

ISIL announced the revival of slavery as an institution. In 2015 the official slave prices set by ISIL were following:

Children aged 1 to 9 were sold for 200,000 dinars ($169).

Women and children 10 to 20 years old for 150,000 dinars ($127).

Women 20 to 30 years old for 100,000 dinar ($85).

Women 30 to 40 years old are 75,000 dinar ($63).

Women 40 to 50 years old for 50,000 dinar ($42).

However some slaves have been sold for as little as a pack of cigarettes. Sex slaves were sold to Saudi Arabia, other Persian Gulf states and Turkey.

Slavery has existed all throughout Asia, and forms of slavery still exist today.

Scholars differ as to whether or not slaves and the institution of slavery existed in ancient India. These English words have no direct, universally accepted equivalent in Sanskrit or other Indian languages, but some scholars translate the word , mentioned in texts like Manu Smriti, as slaves. Ancient historians who visited India offer the closest insights into the nature of Indian society and slavery in other ancient civilizations. For example, the Greek historian Arrian, who chronicled India about the time of Alexander the Great, wrote in his Indika,

The Indians do not even use aliens as slaves, much less a countryman of their own.

Qin dynasty (221-206 BC) Men sentenced to castration became eunuch slaves of the Qin dynasty state and as a result they were made to do forced labor, on projects like the Terracotta Army. The Qin government confiscated the property and enslaved the families of those who received castration as a punishment for rape.
Slaves were deprived of their rights and connections to their families.

Han dynasty (206 BC - 220 AD) One of Emperor Gao's first acts was to set free from slavery agricultural workers who were enslaved during the Warring States period, although domestic servants retained their status.

Men punished with castration during the Han dynasty were also used as slave labor.

Deriving from earlier Legalist laws, the Han dynasty set in place rules that the property of and families of criminals doing three years of hard labor or sentenced to castration were to have their families seized and kept as property by the government.

During the millennium long Chinese domination of Vietnam, Vietnam was a great source of slave girls who were used as sex slaves in China. The slave girls of Viet were even eroticized in Tang dynasty poetry.

The Islamic invasions, starting in the 8th century, also resulted in hundreds of thousands of Indians being enslaved by the invading armies, one of the earliest being the armies of the Umayyad commander Muhammad bin Qasim. Qutb-ud-din Aybak, a Turkic slave of Muhammad Ghori rose to power following his master's death. For almost a century, his descendants ruled North-Central India in form of Slave Dynasty. Several slaves were also brought to India by the Indian Ocean trades; for example, the Siddi are descendants of Bantu slaves brought to India by Arab and Portuguese merchants.

Andre Wink summarizes the slavery in 8th and 9th century India as follows,

(During the invasion of Muhammad al-Qasim), invariably numerous women and children were enslaved. The sources insist that now, in dutiful conformity to religious law, 'the one-fifth of the slaves and spoils' were set apart for the caliph's treasury and despatched to Iraq and Syria. The remainder was scattered among the army of Islam. At Rūr, a random 60,000 captives reduced to slavery. At Brahamanabad 30,000 slaves were allegedly taken. At Multan 6,000. Slave raids continued to be made throughout the late Umayyad period in Sindh, but also much further into Hind, as far as Ujjain and Malwa. The Abbasid governors raided Punjab, where many prisoners and slaves were taken.

In the early 11th century Tarikh al-Yamini, the Arab historian Al-Utbi recorded that in 1001 the armies of Mahmud of Ghazna conquered Peshawar and Waihand (capital of Gandhara) after Battle of Peshawar (1001), "in the midst of the land of Hindustan", and captured some 100,000 youths. Later, following his twelfth expedition into India in 1018-19, Mahmud is reported to have returned with such a large number of slaves that their value was reduced to only two to ten dirhams each. This unusually low price made, according to Al-Utbi, "merchants [come] from distant cities to purchase them, so that the countries of Central Asia, Iraq and Khurasan were swelled with them, and the fair and the dark, the rich and the poor, mingled in one common slavery". Elliot and Dowson refer to "five hundred thousand slaves, beautiful men and women.". Later, during the Delhi Sultanate period (1206-1555), references to the abundant availability of low-priced Indian slaves abound. Levi attributes this primarily to the vast human resources of India, compared to its neighbors to the north and west (India's Mughal population being approximately 12 to 20 times that of Turan and Iran at the end of the 16th century).

Slavery and empire-formation tied in particularly well with iqta and it is within this context of Islamic expansion that elite slavery was later commonly found. It became the predominant system in North India in the thirteenth century and retained considerable importance in the fourteenth century. Slavery was still vigorous in fifteenth-century Bengal, while after that date it shifted to the Deccan where it persisted until the seventeenth century. It remained present to a minor extent in the Mughal provinces throughout the seventeenth century and had a notable revival under the Afghans in North India again in the eighteenth century.

The Delhi sultanate obtained thousands of slaves and eunuch servants from the villages of Eastern Bengal (a widespread practice which Mughal emperor Jahangir later tried to stop). Wars, famines, pestilences drove many villagers to sell their children as slaves. The Muslim conquest of Gujarat in Western India had two main objectives. The conquerors demanded and more often forcibly wrested both land owned by Hindus and Hindu women. Enslavement of women invariably led to their conversion to Islam. In battles waged by Muslims against Hindus in Malwa and Deccan plateau, a large number of captives were taken. Muslim soldiers were permitted to retain and enslave POWs as plunder.

The first Bahmani sultan, Alauddin Bahman Shah is noted to have captured 1,000 singing and dancing girls from Hindu temples after he battled the northern Carnatic chieftains. The later Bahmanis also enslaved civilian women and children in wars; many of them were converted to Islam in captivity. About the Mughal empire, W.H. Moreland observed, "it became a fashion to raid a village or group of villages without any obvious justification, and carry off the inhabitants as slaves."

During the rule of Shah Jahan, many peasants were compelled to sell their women and children into slavery to meet the land revenue demand. Slavery was officially abolished in British India by the Indian Slavery Act, 1843. However, in modern India, Pakistan and Nepal, there are millions of bonded laborers, who work as slaves to pay off debts.

The Tang dynasty purchased Western slaves from the Radanite Jews. Tang Chinese soldiers and pirates enslaved Koreans, Turks, Persians, Indonesians, and people from Inner Mongolia, Central Asia, and northern India. The greatest source of slaves came from southern tribes, including Thais and aboriginals from the southern provinces of Fujian, Guangdong, Guangxi, and Guizhou. Malays, Khmers, Indians, and black Africans were also purchased as slaves in the Tang dynasty. Slavery was prevalent until the late 19th century and early 20th century China. All forms of slavery have been illegal in China since 1910.

Slavery in Japan was, for most of its history, indigenous, since the export and import of slaves was restricted by Japan being a group of islands. In late-16th-century Japan, slavery was officially banned; but forms of contract and indentured labor persisted alongside the period penal codes' forced labor. During the Second Sino-Japanese War and the Pacific War, the Japanese military used millions of civilians and prisoners of war from several countries as forced laborers.

In Korea, slavery was officially abolished with the Gabo Reform of 1894. During the Joseon period, in times of poor harvest and famine, many peasants voluntarily sold themselves into the nobi system in order to survive.

In Southeast Asia, there was a large slave class in Khmer Empire who built the enduring monuments in Angkor Wat and did most of the heavy work. Between the 17th and the early 20th centuries one-quarter to one-third of the population of some areas of Thailand and Burma were slaves. By the 19th century, Bhutan had developed a slave trade with Sikkim and Tibet, also enslaving British subjects and Brahmins. According to the International Labour Organization (ILO), during the early 21st century an estimated 800,000 people are subject to forced labor in Myanmar.

Slavery in pre-Spanish Philippines was practiced by the tribal Austronesian peoples who inhabited the culturally diverse islands. The neighbouring Muslim states conducted slave raids from the 1600s into the 1800s in coastal areas of the Gulf of Thailand and the Philippine islands. Slaves in Toraja society in Indonesia were family property. People would become slaves when they incurred a debt. Slaves could also be taken during wars, and slave trading was common. Torajan slaves were sold and shipped out to Java and Siam. Slaves could buy their freedom, but their children still inherited slave status. Slavery was abolished in 1863 in all Dutch colonies.

Records of slavery in Ancient Greece go as far back as Mycenaean Greece. The origins are not known, but it appears that slavery became an important part of the economy and society only after the establishment of cities. Slavery was common practice and an integral component of ancient Greece, as it was in other societies of the time, including ancient Israel. It is estimated that in Athens, the majority of citizens owned at least one slave. Most ancient writers considered slavery not only natural but necessary, but some isolated debate began to appear, notably in Socratic dialogues. The Stoics produced the first condemnation of slavery recorded in history.

During the 8th and the 7th centuries BC, in the course of the two Messenian Wars, the Spartans reduced an entire population to a pseudo-slavery called . According to Herodotus (IX, 28-29), helots were seven times as numerous as Spartans. Following several helot revolts around the year 600 BC, the Spartans restructured their city-state along authoritarian lines, for the leaders decided that only by turning their society into an armed camp could they hope to maintain control over the numerically dominant helot population. In some Ancient Greek city-states, about 30% of the population consisted of slaves, but paid and slave labor seem to have been equally important.

Romans inherited the institution of slavery from the Greeks and the Phoenicians. As the Roman Republic expanded outward, it enslaved entire populations, thus ensuring an ample supply of laborers to work in Rome's farms, quarries and households. The people subjected to Roman slavery came from all over Europe and the Mediterranean. Such oppression by an elite minority eventually led to slave revolts; the Third Servile War led by Spartacus was the most famous and severe. Greeks, Berbers, Germans, Britons, Slavs, Thracians, Gauls (or Celts), Jews, Arabs and many more ethnic groups were enslaved to be used for labor, and also for amusement (e.g. gladiators and sex slaves). If a slave ran away, they were liable to be crucified.

The overall impact of slavery on the Italian genetics was insignificant though, because the slaves imported in Italy were native Europeans, and very few if any of them had extra European origin. This has been further confirmed by recent biochemical analysis of 166 skeletons from three non-elite imperial-era cemeteries in the vicinity of Rome (where the bulk of the slaves lived), which shows that only 1 individual definitely came from outside of Europe (North Africa), and another 2 possibly did, but results are inconclusive. In the rest of the Italian peninsula, the amount of non European slaves was definitively much lower than that.

The chaos of invasion and frequent warfare also resulted in victorious parties taking slaves throughout Europe in the early Middle Ages. St. Patrick, himself captured and sold as a slave, protested against an attack that enslaved newly baptized Christians in his "Letter to the Soldiers of Coroticus". As a commonly traded commodity, like cattle, slaves could become a form of internal or trans-border currency. Slavery during the Early Middle Ages had several distinct sources.

The Vikings raided across Europe, but took the most slaves in raids on the British Isles and in Eastern Europe. While the Vikings kept some slaves as servants, known as , they sold most captives in the Byzantine or Islamic markets. In the West, their target populations were primarily English, Irish, and Scottish, while in the East they were mainly Slavs. The Viking slave-trade slowly ended in the 11th century, as the Vikings settled in the European territories they had once raided. They converted serfs to Christianity and themselves merged with the local populace.

In central Europe, specifically the Frankish/German/Holy Roman Empire of Charlemagne, raids and wars to the east generated a steady supply of slaves from the Slavic captives of these regions. Because of high demand for slaves in the wealthy Muslim empires of Northern Africa, Spain, and the Near East, especially for slaves of European descent, a market for these slaves rapidly emerged. So lucrative was this market that it spawned an economic boom in central and western Europe, today known as the Carolingian Renaissance. This boom period for slaves stretched from the early Muslim conquests to the High Middle Ages but declined in the later Middle Ages as the Islamic Golden Age waned.

Medieval Spain and Portugal saw almost constant warfare between Muslims and Christians. Al-Andalus sent periodic raiding expeditions to loot the Iberian Christian kingdoms, bringing back booty and slaves. In a raid against Lisbon, Portugal in 1189, for example, the Almohad caliph Yaqub al-Mansur took 3,000 female and child captives. In a subsequent attack upon Silves, Portugal in 1191, his governor of Córdoba took 3,000 Christian slaves.

The Byzantine-Ottoman wars and the Ottoman wars in Europe resulted in the taking of large numbers of Christian slaves and using or selling them in the Islamic world too. After the battle of Lepanto the victors freed approximately 12,000 Christian galley slaves from the Ottoman fleet.

Similarly, Christians sold Muslim slaves captured in war. The Order of the Knights of Malta attacked pirates and Muslim shipping, and their base became a centre for slave trading, selling captured North Africans and Turks. Malta remained a slave market until well into the late 18th century. One thousand slaves were required to man the galleys (ships) of the Order.

Poland banned slavery in the 15th century; in Lithuania, slavery was formally abolished in 1588; the institution was replaced by the second enserfment. Slavery remained a minor institution in Russia until 1723, when Peter the Great converted the household slaves into house serfs. Russian agricultural slaves were formally converted into serfs earlier, in 1679. The escaped Russian serfs and kholops formed autonomous communities in the southern steppes, where they became known as Cossacks (meaning "outlaws").

Capture in war, voluntary servitude and debt slavery became common within the British Isles before 1066. Slaves were routinely bought and sold. Running away was also common and slavery was never a major economic factor in the British Isles during the Middle Ages. Ireland and Denmark provided markets for captured Anglo-Saxon and Celtic slaves. Pope Gregory I reputedly made the pun, Non Angli, sed Angeli ("Not Angles, but Angels"), after a response to his query regarding the identity of a group of fair-haired Angles, slave children whom he had observed in the marketplace. After the Norman Conquest, the law no longer supported chattel slavery and slaves became part of the larger body of serfs.

Barbary pirates and Maltese corsairs both raided for slaves and purchased slaves from European merchants, often the Radhanites, one of the few groups who could easily move between the Christian and Islamic worlds.

In the late Middle Ages, from 1100 to 1500, the European slave-trade continued, though with a shift from being centered among the Western Mediterranean Islamic nations to the Eastern Christian and Muslim states. The city-states of Venice and Genoa controlled the Eastern Mediterranean from the 12th century and the Black Sea from the 13th century. They sold both Slavic and Baltic slaves, as well as Georgians, Turks, and other ethnic groups of the Black Sea and Caucasus. The sale of European slaves by Europeans slowly ended as the Slavic and Baltic ethnic groups Christianized by the Late Middle Ages. European slaves did not pass on an inherited status and was thus more akin to forced labor, or indentured servitude.

From the 1440s into the 18th century, Europeans from Italy, Spain, Portugal, France, and England were sold into slavery by North Africans, as described in the book "Christian Slaves, Muslim Masters". This same book states that "white slavery had been minimised or ignored because academics preferred to treat Europeans as evil colonialists rather than as victims." and likely overestimates the number of slaves taken. In 1575, the Tatars captured over 35,000 Ukrainians; a 1676 raid took almost 40,000. About 60,000 Ukrainians were captured in 1688; some were ransomed, but most were sold into slavery. Some of the Roma people were enslaved over five centuries in Romania until abolition in 1864 (see Slavery in Romania).

The Mongol invasions and conquests in the 13th century also resulted in taking numerous captives into slavery. The Mongols enslaved skilled individuals, women and children and marched them to Karakorum or Sarai, whence they were sold throughout Eurasia. Many of these slaves were shipped to the slave market in Novgorod.

Slave commerce during the Late Middle Ages was mainly in the hands of Venetian and Genoese merchants and cartels, who were involved in the slave trade with the Golden Horde. In 1382 the Golden Horde under Khan Tokhtamysh sacked Moscow, burning the city and carrying off thousands of inhabitants as slaves. Between 1414 and 1423, some 10,000 eastern European slaves were sold in Venice. Genoese merchants organized the slave trade from the Crimea to Mamluk Egypt. For years, the Khanates of Kazan and Astrakhan routinely made raids on Russian principalities for slaves and to plunder towns. Russian chronicles record about 40 raids by Kazan Khans on the Russian territories in the first half of the 16th century.

In 1441 Haci I Giray declared independence from the Golden Horde and established the Crimean Khanate. For a long time, until the early 18th century, the khanate maintained an extensive slave-trade with the Ottoman Empire and the Middle East. In a process called the "harvesting of the steppe" they enslaved many Slavic peasants. About 30 major Tatar raids were recorded into Muscovite territories between 1558 and 1596.

Moscow was repeatedly a target. In 1521, the combined forces of Crimean Khan Mehmed Giray and his Kazan allies attacked the city and captured thousands of slaves. In 1571, the Crimean Tatars attacked and sacked Moscow, burning everything but the Kremlin and taking thousands of captives as slaves. In Crimea, about 75% of the population consisted of slaves.

In the Viking era beginning circa 793, the Norse raiders often captured and enslaved militarily weaker peoples they encountered. The Nordic countries called their slaves ( Old Norse: Þræll). The thralls were mostly from Western Europe, among them many Franks, Frisians, Anglo-Saxons, and both Irish and Britonnic Celts. Many Irish slaves travelled in expeditions for the colonization of Iceland. The Norse also took German, Baltic, Slavic and Latin slaves. The slave trade was one of the pillars of Norse commerce during the 6th through 11th centuries. The 10th-century Persian traveller Ibn Rustah described how Swedish Vikings, the Varangians or Rus, terrorized and enslaved the Slavs taken in their raids along the Volga River. The thrall system was finally abolished in the mid-14th century in Scandinavia.

Mediterranean powers frequently sentenced convicted criminals to row in the war- galleys of the state (initially only in time of war). After the revocation of the Edict of Nantes in 1685 and Camisard rebellion, the French Crown filled its galleys with French Huguenots, Protestants condemned for resisting the state. Galley-slaves lived and worked in such harsh conditions that many did not survive their terms of sentence, even if they survived shipwreck and slaughter or torture at the hands of enemies or of pirates. Naval forces often turned 'infidel' prisoners-of-war into galley-slaves. Several well-known historical figures served time as galley slaves after being captured by the enemy-the Ottoman corsair and admiral Turgut Reis and the Knights Hospitaller Grand Master Jean Parisot de la Valette among them.

Denmark-Norway was the first European country to ban the slave trade. This happened with a decree issued by King Christian VII of Denmark in 1792, to become fully effective by 1803. Slavery as an institution was not banned until 1848. At this time Iceland was a part of Denmark-Norway but slave trading had been abolished in Iceland in 1117 and had never been reestablished.

Slavery in the French Republic was abolished on 4 February 1794, including in its colonies. The lengthy Haitian Revolution by its slaves and free people of color established Haiti as a free republic in 1804 ruled by blacks, the first of its kind. At the time of the revolution, Haiti was known as Saint-Domingue and was a colony of France. Napoleon Bonaparte gave up on Haiti in 1803, but re-established slavery in Guadeloupe and Martinique in 1804, at the request of planters of the Caribbean colonies. Slavery was permanently abolished in the French empire during the French Revolution of 1848.

The 15th-century Portuguese exploration of the African coast is commonly regarded as the harbinger of European colonialism. In 1452, Pope Nicholas V issued the papal bull Dum Diversas, granting Afonso V of Portugal the right to reduce any "Saracens, pagans and any other unbelievers" to hereditary slavery which legitimized slave trade under Catholic beliefs of that time. This approval of slavery was reaffirmed and extended in his Romanus Pontifex bull of 1455. These papal bulls came to serve as a justification for the subsequent era of the slave trade and European colonialism. Although for a short period as in 1462, Pius II declared slavery to be "a great crime". The followers of the church of England and Protestants did not use the papal bull as a justification. The position of the church was to condemn the slavery of Christians, but slavery was regarded as an old established and necessary institution which supplied Europe with the necessary workforce. In the 16th century, African slaves had replaced almost all other ethnicities and religious enslaved groups in Europe. Within the Portuguese territory of Brazil, and even beyond its original borders, the enslavement of Native Americans was carried out by the Bandeirantes.

Among many other European slave markets, Genoa, and Venice were some well-known markets, their importance and demand growing after the great plague of the 14th century which decimated much of the European workforce. The maritime town of Lagos, Portugal, was the first slave market created in Portugal for the sale of imported African slaves, the Mercado de Escravos, which opened in 1444. In 1441, the first slaves were brought to Portugal from northern Mauritania. Prince Henry the Navigator, major sponsor of the Portuguese African expeditions, as of any other merchandise, taxed one fifth of the selling price of the slaves imported to Portugal. By the year 1552 African slaves made up 10 percent of the population of Lisbon. In the second half of the 16th century, the Crown gave up the monopoly on slave trade and the focus of European trade in African slaves shifted from import to Europe to slave transports directly to tropical colonies in the Americas-in the case of Portugal, especially Brazil. In the 15th century, one-third of the slaves were resold to the African market in exchange of gold. Slavery was abolished in mainland Portugal and Portuguese India in 1761. It was finally abolished in all Portuguese colonies in 1869.

The Spaniards were the first Europeans to use African slaves in the New World on islands such as Cuba and Hispaniola, due to a shortage of labor caused by the spread of diseases, and so the Spanish colonists gradually became involved in the Atlantic slave trade. The first African slaves arrived in Hispaniola in 1501; by 1517, the natives had been "virtually annihilated" mostly to diseases. The problem of the justness of Native American's slavery was a key issue for the Spanish Crown. It was Charles V who gave a definite answer to this complicated and delicate matter. To that end, on 25 November 1542, the Emperor abolished slavery by decree in his Leyes Nuevas New Laws. This bill was based on the arguments given by the best Spanish theologists and jurists who were unanimous in the condemnation of such slavery as unjust; they declared it illegitimate and outlawed it from America-not just the slavery of Spaniards over Natives-but also the type of slavery practiced among the Natives themselves Thus, Spain became the first country to officially abolish slavery.

However, in the Spanish colonies of Cuba and Puerto Rico, where sugarcane production was highly profitable based on slave labor, African slavery persisted until 1873 in Puerto Rico "with provisions for periods of apprenticeship", and 1886 in Cuba.

Although slavery was illegal inside the Netherlands it flourished throughout the Dutch Empire in the Americas, Africa, Ceylon and Indonesia. The Dutch Slave Coast ( Dutch: Slavenkust) referred to the trading posts of the Dutch West India Company on the Slave Coast, which lie in contemporary Ghana, Benin, Togo and Nigeria. Initially the Dutch shipped slaves to northern Brazil, and during the second half of the 17th century they had a controlling interest in the trade to the Spanish colonies. Today's Suriname and Guyana became prominent markets in the 18th century. Between 1612 and 1872, the Dutch operated from some 10 fortresses along the Gold Coast (now Ghana), from which slaves were shipped across the Atlantic. Dutch involvement on the Slave Coast increased with the establishment of a trading post in Offra in 1660. Willem Bosman writes in his Nauwkeurige beschrijving van de Guinese Goud- Tand- en Slavekust (1703) that Allada was also called Grand Ardra, being the larger cousin of Little Ardra, also known as Offra. From 1660 onward, Dutch presence in Allada and especially Offra became more permanent. A report from this year asserts Dutch trading posts, apart from Allada and Offra, in Benin City, Grand-Popo, and Savi.

The Offra trading post soon became the most important Dutch office on the Slave Coast. According to a 1670 report, annually 2,500 to 3,000 slaves were transported from Offra to the Americas. These numbers were only feasible in times of peace, however, and dwindled in time of conflict. From 1688 onward, the struggle between the Aja king of Allada and the peoples on the coastal regions, impeded the supply of slaves. The Dutch West India Company chose the side of the Aja king, causing the Offra office to be destroyed by opposing forces in 1692. By 1650 the Dutch had the pre-eminent slave trade in Europe and South East Asia. Later, trade shifted to Ouidah. On the instigation of Governor-General of the Dutch Gold Coast Willem de la Palma, Jacob van den Broucke was sent in 1703 as "opperkommies" (head merchant) to the Dutch trading post at Ouidah, which according to sources was established around 1670. Political unrest caused the Dutch to abandon their trading post at Ouidah in 1725, and they then moved to Jaquim, at which place they built Fort Zeelandia. The head of the post, Hendrik Hertog, had a reputation for being a successful slave trader. In an attempt to extend his trading area, Hertog negotiated with local tribes and mingled in local political struggles. He sided with the wrong party, however, leading to a conflict with Director-General Jan Pranger and to his exile to the island of Appa in 1732. The Dutch trading post on this island was extended as the new centre of the slave trade. In 1733, Hertog returned to Jaquim, this time extending the trading post into Fort Zeelandia. The revival of the slave trade at Jaquim was only temporary, however, as his superiors at the Dutch West India Company noticed that Hertog's slaves were more expensive than at the Gold Coast. From 1735, Elmina became the preferred spot to trade slaves. As of 1778, it was estimated that the Dutch were shipping approximately 6,000 Africans for enslavement in the Dutch West Indies each year. Slavery also characterised the Dutch possessions in Indonesia, Ceylon and South Africa, where Indonesians have made a significant contribution to the Cape Coloured population of that country. The Dutch part in the Atlantic slave trade is estimated at 5-7 percent, as they shipped about 550,000-600,000 African slaves across the Atlantic, about 75,000 of whom died on board before reaching their destinations. From 1596 to 1829, the Dutch traders sold 250,000 slaves in the Dutch Guianas, 142,000 in the Dutch Caribbean islands, and 28,000 in Dutch Brazil. In addition, tens of thousands of slaves, mostly from India and some from Africa, were carried to the Dutch East Indies. The Netherlands was one of the last countries to abolish slavery in 1863. Although the decision was made in 1848, it took many years for the law to be implemented. Furthermore, slaves in Suriname would be fully free only in 1873, since the law stipulated that there was to be a mandatory 10-year transition.

Barbary Corsairs continued to trade in European slaves into the Modern time-period. Muslim pirates, primarily Algerians with the support of the Ottoman Empire, raided European coasts and shipping from the 16th to the 19th centuries, and took thousands of captives, whom they sold or enslaved. Many were held for ransom, and European communities raised funds such as Malta's Monte della Redenzione degli Schiavi to buy back their citizens. The raids gradually ended with the naval decline of the Ottoman Empire in the late 16th and 17th centuries, as well as the European conquest of North Africa throughout the 19th century.

From 1609 to 1616, England lost 466 merchant ships to Barbary pirates. 160 English ships were captured by Algerians between 1677 and 1680. Many of the captured sailors were made into slaves and held for ransom. The corsairs were no strangers to the South West of England where raids were known in a number of coastal communities. In 1627 Barbary Pirates under command of the Dutch renegade Jan Janszoon (Murat Reis), operating from the Moroccan port of Salé, occupied the island of Lundy. During this time there were reports of captured slaves being sent to Algiers.

Ireland, despite its northern position, was not immune from attacks by the corsairs. In June 1631 Janszoon, with pirates from Algiers and armed troops of the Ottoman Empire, stormed ashore at the little harbor village of Baltimore, County Cork. They captured almost all the villagers and took them away to a life of slavery in North Africa. The prisoners were destined for a variety of fates-some lived out their days chained to the oars as galley slaves, while others would spend long years in the scented seclusion of the harem or within the walls of the sultan's palace. Only two of them ever saw Ireland again.

The Congress of Vienna (1814-15), which ended the Napoleonic Wars, led to increased European consensus on the need to end Barbary raiding. The sacking of Palma on the island of Sardinia by a Tunisian squadron, which carried off 158 inhabitants, roused widespread indignation. Britain had by this time banned the slave trade and was seeking to induce other countries to do likewise. States that were more vulnerable to the corsairs complained that Britain cared more for ending the trade in African slaves than stopping the enslavement of Europeans and Americans by the Barbary States.

In order to neutralise this objection and further the anti-slavery campaign, in 1816 Britain sent Lord Exmouth to secure new concessions from Tripoli, Tunis, and Algiers, including a pledge to treat Christian captives in any future conflict as prisoners of war rather than slaves. He imposed peace between Algiers and the kingdoms of Sardinia and Sicily. On his first visit, Lord Exmouth negotiated satisfactory treaties and sailed for home. While he was negotiating, a number of Sardinian fishermen who had settled at Bona on the Tunisian coast were brutally treated without his knowledge. As Sardinians they were technically under British protection, and the government sent Exmouth back to secure reparation. On 17 August, in combination with a Dutch squadron under Admiral Van de Capellen, Exmouth bombarded Algiers. Both Algiers and Tunis made fresh concessions as a result.

The Barbary states had difficulty securing uniform compliance with a total prohibition of slave-raiding, as this had been traditionally of central importance to the North African economy. Slavers continued to take captives by preying on less well-protected peoples. Algiers subsequently renewed its slave-raiding, though on a smaller scale. Europeans at the Congress of Aix-la-Chapelle in 1818 discussed possible retaliation. In 1820 a British fleet under Admiral Sir Harry Neal bombarded Algiers. Corsair activity based in Algiers did not entirely cease until France conquered the state in 1830.

The Crimeans frequently mounted raids into the Danubian principalities, Poland-Lithuania, and Muscovy to enslave people whom they could capture; for each captive, the khan received a fixed share (savğa) of 10% or 20%. These campaigns by Crimean forces were either sefers ("sojourns" - officially declared military operations led by the khans themselves), or çapuls ("despoiling" - raids undertaken by groups of noblemen, sometimes illegally because they contravened treaties concluded by the khans with neighbouring rulers).

For a long time, until the early 18th century, the Crimean Khanate maintained a massive slave trade with the Ottoman Empire and the Middle East, exporting about 2 million slaves from Russia and Poland-Lithuania over the period 1500-1700. Caffa (modern Feodosia) became one of the best-known and significant trading ports and slave markets. In 1769 the last major Tatar raid saw the capture of 20,000 Russian and Ruthenian slaves.

Author and historian Brian Glyn Williams writes:

Fisher estimates that in the sixteenth century the Polish-Lithuanian Commonwealth lost around 20,000 individuals a year and that from 1474 to 1694, as many as a million Commonwealth citizens were carried off into Crimean slavery.

Early modern sources are full of descriptions of sufferings of Christian slaves captured by the Crimean Tatars in the course of their raids:

It seems that the position and everyday conditions of a slave depended largely on his/her owner. Some slaves indeed could spend the rest of their days doing exhausting labor: as the Crimean vizir (minister) Sefer Gazi Aga mentions in one of his letters, the slaves were often "a plough and a scythe" of their owners. Most terrible, perhaps, was the fate of those who became galley-slaves, whose sufferings were poeticized in many Ukrainian dumas (songs). ... Both female and male slaves were often used for sexual purposes.

Britain played a prominent role in the Atlantic slave trade, especially after 1640, when sugar cane was introduced to the region. At first, most were white Britons, or Irish, enslaved as indentured labour - for a fixed period - in the West Indies. These people may have been criminals, political rebels, the poor with no prospects or others who were simply tricked or kidnapped. Slavery was a legal institution in all of the 13 American colonies and Canada (acquired by Britain in 1763). The profits of the slave trade and of West Indian plantations amounted to 5% of the British economy at the time of the Industrial Revolution.

A little-known incident in the career of Judge Jeffreys refers to an assize in Bristol in 1685 when he made the mayor of the city, then sitting fully robed beside him on the bench, go into the dock and be fined £1000 for being a 'kidnapping knave'; some Bristol traders at the time were known at the time to kidnap their own countrymen and ship them away as slaves.

Somersett's case in 1772 was generally taken at the time to have decided that the condition of slavery did not exist under English law in England. In 1785, English poet William Cowper wrote: "We have no slaves at home - Then why abroad? Slaves cannot breathe in England; if their lungs receive our air, that moment they are free. They touch our country, and their shackles fall. That's noble, and bespeaks a nation proud. And jealous of the blessing. Spread it then, And let it circulate through every vein." However, slavery continued to thrive in England itself, much like it did in the British Empire, until full emancipation in the 1830s. In 1807, following many years of lobbying by the abolitionist movement, led primarily by William Wilberforce, the British Parliament voted to make the slave trade illegal anywhere in the Empire with the Slave Trade Act 1807. Thereafter Britain took a prominent role in combating the trade, and slavery itself was abolished in the British Empire (except for India) with the Slavery Abolition Act 1833. Between 1808 and 1860, the West Africa Squadron seized approximately 1,600 slave ships and freed 150,000 Africans who were aboard. Action was also taken against African leaders who refused to agree to British treaties to outlaw the trade. Akitoye, the 11th Oba of Lagos, is famous for having used British involvement to regain his rule in return for suppressing slavery among the Yoruba people of Lagos in 1851. Anti-slavery treaties were signed with over 50 African rulers. In 1839, the world's oldest international human rights organization, Anti-Slavery International, was formed in Britain by Joseph Sturge, which worked to outlaw slavery in other countries.

After 1833, the freed African slaves declined employment in the cane fields. This led to the importation of indentured labour again - mainly from India, and also China.

In 1811, Arthur William Hodge was executed for the murder of a slave in the British West Indies. He was not, however, as some have claimed, the first white person to have been lawfully executed for the murder of a slave.

During World War II Nazi Germany operated several categories of Arbeitslager (Labor Camps) for different categories of inmates. The largest number of them held Polish and Jewish civilians forcibly abducted in the occupied countries (see Łapanka) to provide labor in the German war industry, repair bombed railroads and bridges or work on farms. By 1944, 20% of all workers were foreigners, either civilians or prisoners of war.

This is not classed as slavery per se, as defined in the first paragraph, i.e. slavery under this definition does not include other forced labour systems, such as historical forced labor by prisoners, labor camps, or other forms of unfree labor, in which labourers are not legally considered property. Slavery typically requires a shortage of labor and a surplus of land to be viable.

As agreed by the Allies at the Yalta conference Germans were used as forced labor as part of the reparations to be extracted. By 1947 it is estimated that 400,000 Germans (both civilians and POWs) were being used as forced labor by the U.S., France, the UK and the Soviet Union. German prisoners were for example forced to clear minefields in France and the Low Countries. By December 1945 it was estimated by French authorities that 2,000 German prisoners were being killed or injured each month in accidents. In Norway the last available casualty record, from 29 August 1945, shows that by that time a total of 275 German soldiers died while clearing mines, while 392 had been injured. Death rates for the German civilians doing forced labor in the Soviet Union ranged between 19% and 39%, depending on category.

In the first half of the 19th century, small-scale slave raids took place across Polynesia to supply labor and sex workers for the whaling and sealing trades, with examples from both the westerly and easterly extremes of the Polynesian triangle. By the 1860s this had grown to a larger scale operation with Peruvian slave raids in the South Sea Islands to collect labor for the guano industry.

Ancient Hawaii was a caste society. People were born into specific social classes. Kauwa were those of the outcast or slave class. They are believed to have been war captives, or the descendants of war captives. Marriage between higher castes and the kauwa was strictly forbidden. The kauwa worked for the chiefs and were often used as human sacrifices at the luakini heiau. (They were not the only sacrifices; law-breakers of all castes or defeated political opponents were also acceptable as victims.)

The kapu system was abolished during the ʻAi Noa in 1819, and with it the distinction between the kauwā slave class and the makaʻāinana (commoners). The 1852 Constitution of the Kingdom of Hawaii officially made slavery illegal.

Before the arrival of European settlers, each Maori tribe () considered itself a separate entity equivalent to a nation. In traditional Maori society of Aotearoa, prisoners of war became taurekareka, slaves, unless released, ransomed or eaten. With some exceptions, the child of a slave remained a slave.

As far as it is possible to tell, slavery seems to have increased in the early 19th century with increased numbers of prisoners being taken by Māori military leaders, such as Hongi Hika and Te Rauparaha to satisfy the need for labor in the Musket Wars, to supply whalers and traders with food, flax and timber in return for western goods. The intertribal Musket Wars lasted 1807 to 1843 when large numbers of slaves were captured by northern tribes who had acquired muskets. About 20,000 Maori died in the wars which were concentrated in the North Island. An unknown number of slaves were captured. Northern tribes used slaves (called mokai) to grow large areas of potatoes for trade with visiting ships. Chiefs started an extensive sex trade in the Bay of Islands in the 1830s using mainly slave girls. By 1835 about 70-80 ships per year called into the port. One French captain described the impossibility of getting rid of the girls who swarmed over his ship outnumbering his crew of 70 by 3 to 1. All payments to the girls were stolen by the chief. By 1833 Christianity had become established in the north and large numbers of slaves were freed. However two Taranaki tribes, Ngati Tama and Ngati Mutunga, displaced by the wars carried out a carefully planned invasion of the Chatham Islands, 800 km east of Christchurch, in 1835. About 15% of the Polynesian Moriori natives who had migrated to the islands at about 1500 CE were killed, with many women being tortured to death. The remaining population was enslaved for the purpose of growing food, especially potatoes. The Moriori were treated in an inhumane and degrading manner for many years. Their culture was banned and they were forbidden to marry. Slavery was outlawed when the British entered into a constitutional arrangement with New Zealand in 1840 via the Treaty of Waitangi, although it did not end completely until government was effectively extended over the whole of the country with the defeat of the Kingi movement in the Wars of the mid-1860s.

Some Maori took Moriori partners. The state of enslavement of Moriori lasted until the 1860s although it had been discouraged by CMS missionaries in North New Zealand from the late 1820s. In 1870 Ngati Mutunga, one of the invading tribes, argued before the Native Land Court in New Zealand that their gross mistreatment of the Moriori was standard Maori practice or tikanga.

One group of Polynesians who migrated to the Chatham Islands became the Moriori who developed a largely pacifist culture. It was originally speculated that they settled the Chathams direct from Polynesia, but it is now widely believed they were disaffected Maori who emigrated from the South Island of New Zealand. Their pacifism left the Moriori unable to defend themselves when the islands were invaded by mainland Māori in the 1830s. Two Taranaki tribes, Ngati Tama and Ngati Mutunga, displaced by the musket wars, carried out a carefully planned invasion of the Chatham Islands, 800 km east of Christchurch, in 1835. About 15% of the Polynesian Moriori natives who had migrated to the islands at about 1500 CE were killed, with many women being tortured to death. The remaining population was enslaved for the purpose of growing food, especially potatoes. The Moriori were treated in an inhumane and degrading manner for many years. Their culture was banned and they were forbidden to marry. Slavery was outlawed when the British annexed New Zealand in 1840, immediately prior to the signing of the Treaty of Waitangi, although it did not end completely until government was effectively extended over the whole of the country with the defeat of the Kingi movement in the Wars of the mid-1860s.

Some 300 Moriori men, women and children were massacred and the remaining 1,200 to 1,300 survivors were enslaved.

Rapa Nui / Easter Island

The isolated island of Rapa Nui/ Easter Island was inhabited by the Rapanui, who suffered a series of slave raids from 1805 or earlier, culminating in a near genocidal experience in the 1860s. The 1805 raid was by American sealers and was one of a series that changed the attitude of the islanders to outside visitors, with reports in the 1820s and 1830s that all visitors received a hostile reception. In December 1862, Peruvian slave raiders took between 1,400 and 2,000 islanders back to Peru to work in the guano industry; this was about a third of the island's population and included much of the island's leadership, the last ariki-mau and possibly the last who could read Rongorongo. After intervention by the French ambassador in Lima, the last 15 survivors were returned to the island, but brought with them smallpox, which further devastated the island.

Slavery has existed, in one form or another, throughout the whole of human history. So, too, have movements to free large or distinct groups of slaves. However, abolitionism should be distinguished from efforts to help a particular group of slaves, or to restrict one practice, such as the slave trade.

Although there were numerous slave revolts in the Caribbean, the only successful uprising came in the French colony of Haiti in the 1790s, where the slaves rose up, killed the mulattoes and whites, and established the independent Republic of Haiti. Europe recoiled in horror.

Cyrus the Great, the founder of Persian Empire prohibited the systematic enslavement of conquered non-combatant population. Cyrus also freed slaves and allowed all deported peoples who were enslaved by preceding Assyrian and Babylonian kings, to return home. It is said that he freed up to 40,000 Jews and allowed them to return home. Cylinder of Cyrus the Great containing the Decree on the conquered non-combatant population.

In 1772, the Somersett Case (R. v. Knowles, ex parte Somersett) of the English Court of King's Bench ruled that it was unlawful for a slave to be forcibly taken abroad. The case has since been misrepresented as finding that slavery was unlawful in England (although not elsewhere in the British Empire). A similar case, that of Joseph Knight, took place in Scotland five years later and ruled slavery to be contrary to the law of Scotland.

Following the work of campaigners in the United Kingdom, such as William Wilberforce and Thomas Clarkson, the Act for the Abolition of the Slave Trade was passed by Parliament on 25 March 1807, coming into effect the following year. The act imposed a fine of £100 for every slave found aboard a British ship. The intention was to outlaw entirely the Atlantic slave trade within the whole British Empire.

The significance of the abolition of the British slave trade lay in the number of people hitherto sold and carried by British slave vessels. Britain shipped 2,532,300 Africans across the Atlantic, equalling 41% of the total transport of 6,132,900 individuals. This made the British empire the biggest slave-trade contributor in the world due to the magnitude of the empire, which made the abolition act all the more damaging to the global trade of slaves. Britain used its diplomatic influence to press other nations into treaties to ban their slave trade and to give the Royal Navy the right to interdict slave ships sailing under their national flag.

The Slavery Abolition Act, passed on 1 August 1833, outlawed slavery itself throughout the British Empire, with the exception of India. On 1 August 1834 slaves became indentured to their former owners in an apprenticeship system for six years. Full emancipation was granted ahead of schedule on 1 August 1838. Britain abolished slavery in both Hindu and Muslim India with the Indian Slavery Act, 1843.

Domestic slavery practised by the educated African coastal elites (as well as interior traditional rulers) in Sierra Leone was abolished in 1928. A study found practices of domestic slavery still widespread in rural areas in the 1970s.

There were slaves in mainland France (especially in trade ports such as Nantes or Bordeaux)., but the institution was never officially authorized there. The legal case of Jean Boucaux in 1739 clarified the unclear legal position of possible slaves in France, and was followed by laws that established registers for slaves in mainland France, who were limited to a three-year stay, for visits or learning a trade. Unregistered "slaves" in France were regarded as free. However, slavery was of vital importance in France's Caribbean possessions, especially Saint-Domingue.

In 1793, influenced by the French Declaration of the Rights of Man of August 1789 and alarmed as the massive slave revolt of August 1791 that had become the Haitian Revolution threatened to ally itself with the British, the French Revolutionary commissioners Sonthonax and Polverel declared general emancipation to reconcile them with France. In Paris, on 4 February 1794, Abbé Grégoire and the Convention ratified this action by officially abolishing slavery in all French territories outside mainland France, freeing all the slaves both for moral and security reasons.

Napoleon came to power in 1799 and soon had grandiose plans for the French sugar colonies; to achieve them he reintroduced slavery. Napoleon's major adventure into the Caribbean-sending 30,000 troops in 1802 to retake Saint Domingue (Haiti) from ex-slaves under Toussaint L'Ouverture who had revolted. Napoleon wanted to preserve France's financial benefits from the colony's sugar and coffee crops; he then planned to establish a major base at New Orleans. He therefore re-established slavery in Haiti and Guadeloupe, where it had been abolished after rebellions. Slaves and black freedmen fought the French for their freedom and independence. Revolutionary ideals played a central role in the fighting for it was the slaves and their allies who were fighting for the revolutionary ideals of freedom and equality, while the French troops under General Charles Leclerc fought to restore the order of the ancien régime. The goal of re-establishing slavery explicitly contradicted the ideals of the French Revolution. The French soldiers were unable to cope with the tropical diseases, and most died of yellow fever. Slavery was reimposed in Guadeloupe but not in Haiti, which became an independent black republic. Napoleon's vast colonial dreams for Egypt, India, the Caribbean, Louisiana, and even Australia were all doomed for lack of a fleet capable of matching Britain's Royal Navy. Realizing the fiasco Napoleon liquidated the Haiti project, brought home the survivors and sold off the huge Louisiana territory to the US in 1803.

In 1794 slavery was abolished in the French Empire. After seizing Lower Egypt in 1798, Napoleon Bonaparte issued a proclamation in Arabic, declaring all men to be free and equal. However, the French bought males as soldiers and females as concubines. Napoleon personally opposed the abolition and restored colonial slavery in 1802, a year after the capitulation of his troops in Egypt.

Victor Schœlcher and the 1848 abolition

The American Colonization Society, the primary vehicle for returning black Americans to greater freedom in Africa, established the colony of Liberia in 1821-23, on the premise that former American slaves would have greater freedom and equality there. The ACS assisted in the movement of thousands of African Americans to Liberia, with its founder Henry Clay stating; "unconquerable prejudice resulting from their color, they never could amalgamate with the free whites of this country. It was desirable, therefore, as it respected them, and the residue of the population of the country, to drain them off". Abraham Lincoln, an enthusiastic supporter of Clay, adopted his position on returning the blacks to their own land.

Slaves in the United States who escaped ownership would often make their way to Canada via the " Underground Railroad". The more famous of the African American abolitionists include former slaves Harriet Tubman, Sojourner Truth and Frederick Douglass. Many more people who opposed slavery and worked for abolition were northern whites, such as William Lloyd Garrison and John Brown. Slavery was legally abolished in 1865 by the Thirteenth Amendment to the United States Constitution.

While abolitionists agreed on the evils of slavery, there were differing opinions on what should happen after African Americans were freed. By the time of Emancipation, African-Americans were now native to the United States and did not want to leave. Most believed that their labor had made the land theirs as well as that of the whites.

The Declaration of the Powers, on the Abolition of the Slave Trade, of 8 February 1815 (Which also formed ACT, No. XV. of the Final Act of the Congress of Vienna of the same year) included in its first sentence the concept of the "principles of humanity and universal morality" as justification for ending a trade that was "odious in its continuance".

The 1926 Slavery Convention, an initiative of the League of Nations, was a turning point in banning global slavery. Article 4 of the Universal Declaration of Human Rights, adopted in 1948 by the UN General Assembly, explicitly banned slavery. The United Nations 1956 Supplementary Convention on the Abolition of Slavery was convened to outlaw and ban slavery worldwide, including child slavery. In December 1966, the UN General Assembly adopted the International Covenant on Civil and Political Rights, which was developed from the Universal Declaration of Human Rights. Article 4 of this international treaty bans slavery. The treaty came into force in March 1976 after it had been ratified by 35 nations.

As of November 2003, 104 nations had ratified the treaty. However, illegal forced labour involves millions of people in the 21st century, 43% for sexual exploitation and 32% for economic exploitation.

In May 2004, the 22 members of the Arab League adopted the Arab Charter on Human Rights, which incorporated the 1990 Cairo Declaration on Human Rights in Islam, which states:

Human beings are born free, and no one has the right to enslave, humiliate, oppress or exploit them, and there can be no subjugation but to God the Most-High.

-  Article 11, Cairo Declaration on Human Rights in Islam, 1990

Currently, the Anti-trafficking Coordination Team Initiative (ACT Team Initiative), a coordinated effort between the U.S. departments of justice, homeland security and labor, addresses human trafficking. The International Labour Organization estimates that there are 20.9 million victims of human trafficking globally, including 5.5 million children, of which 55% are women and girls.

The history of slavery originally was the history of the government's laws and policies toward slavery, and the political debates about it. Black history was promoted very largely at black colleges. The situation changed dramatically with the coming of the Civil Rights Movement of the 1950s. Attention shifted to the enslaved humans, the free blacks, and the struggles of the black community against adversity.

Peter Kolchin described the state of historiography in the early 20th century as follows:

During the first half of the twentieth century, a major component of this approach was often simply racism, manifest in the belief that blacks were, at best, imitative of whites. Thus Ulrich B. Phillips, the era's most celebrated and influential expert on slavery, combined a sophisticated portrait of the white planters' life and behavior with crude passing generalizations about the life and behavior of their black slaves.

Historians James Oliver Horton and Lois E. Horton described Phillips' mindset, methodology and influence:

His portrayal of blacks as passive, inferior people, whose African origins made them uncivilized, seemed to provide historical evidence for the theories of racial inferiority that supported racial segregation. Drawing evidence exclusively from plantation records, letters, southern newspapers, and other sources reflecting the slaveholder's point of view, Phillips depicted slave masters who provided for the welfare of their slaves and contended that true affection existed between master and slave.

Their account of the era rested, as one member of the Dunning school put it, on the assumption of "negro incapacity." Finding it impossible to believe that blacks could ever be independent actors on the stage of history, with their own aspirations and motivations, Dunning et al. portrayed African Americans either as "children", ignorant dupes manipulated by unscrupulous whites, or as savages, their primal passions unleashed by the end of slavery.

In the portrayal of the slave as a victim, the historian Stanley M. Elkins in his 1959 work Slavery: A Problem in American Institutional and Intellectual Life compared the effects of United States slavery to that resulting from the brutality of the Nazi concentration camps. He stated the institution destroyed the will of the slave, creating an "emasculated, docile Sambo" who identified totally with the owner. Elkins' thesis was challenged by historians. Gradually historians recognized that in addition to the effects of the owner-slave relationship, slaves did not live in a "totally closed environment but rather in one that permitted the emergence of enormous variety and allowed slaves to pursue important relationships with persons other than their master, including those to be found in their families, churches and communities."

Economic historians Robert W. Fogel and Stanley L. Engerman in the 1970s, through their work Time on the Cross, portrayed slaves as having internalized the Protestant work ethic of their owners. In portraying the more benign version of slavery, they also argue in their 1974 book that the material conditions under which the slaves lived and worked compared favorably to those of free workers in the agriculture and industry of the time. (This was also an argument of Southerners during the 19th century.)

In the 1970s and 1980s, historians made use of sources such as black music and statistical census data to create a more detailed and nuanced picture of slave life. Relying also on 19th-century autobiographies of ex-slaves (known as slave narratives) and the WPA Slave Narrative Collection, a set of interviews conducted with former slaves in the 1930s by the Federal Writers' Project, historians described slavery as the slaves remembered it. Far from slaves' being strictly victims or content, historians showed slaves as both resilient and autonomous in many of their activities. Despite their exercise of autonomy and their efforts to make a life within slavery, current historians recognize the precariousness of the slave's situation. Slave children quickly learned that they were subject to the direction of both their parents and their owners. They saw their parents disciplined just as they came to realize that they also could be physically or verbally abused by their owners. Historians writing during this era include John Blassingame ( Slave Community), Eugene Genovese ( Roll, Jordan, Roll), Leslie Howard Owens ( This Species of Property), and Herbert Gutman ( The Black Family in Slavery and Freedom).

Important work on slavery has continued; for instance, in 2003 Steven Hahn published the Pulitzer Prize-winning account, A Nation under Our Feet: Black Political Struggles in the Rural South from Slavery to the Great Migration, which examined how slaves built community and political understanding while enslaved, so they quickly began to form new associations and institutions when emancipated, including black churches separate from white control. In 2010, Robert E. Wright published a model that explains why slavery was more prevalent in some areas than others (e.g. southern than northern Delaware) and why some firms (individuals, corporations, plantation owners) chose slave labor while others used wage, indentured, or family labor instead.

Historical revisionism arrived when West Indian historian Eric Williams, a Marxist, in Capitalism and Slavery (1944), rejected this moral explanation and argued that abolition was now more profitable, for a century of sugarcane raising had exhausted the soil of the islands, and the plantations had become unprofitable. It was more profitable to sell the slaves to the government than to keep up operations. The 1807 prohibition of the international trade, Williams argued, prevented French expansion on other islands. Meanwhile, British investors turned to Asia, where labor was so plentiful that slavery was unnecessary. Williams went on to argue that slavery played a major role in making Britain prosperous. The high profits from the slave trade, he said, helped finance the Industrial Revolution. Britain enjoyed prosperity because of the capital gained from the unpaid work of slaves.

Since the 1970s numerous historians have challenged Williams from various angles and Gad Heuman has concluded, "More recent research has rejected this conclusion; it is now clear that the colonies of the British Caribbean profited considerably during the Revolutionary and Napoleonic Wars." In his major attack on the Williams's thesis, Seymour Drescher argues that Britain's abolition of the slave trade in 1807 resulted not from the diminishing value of slavery for Britain but instead from the moral outrage of the British voting public. Critics have also argued that slavery remained profitable in the 1830s because of innovations in agriculture so the profit motive was not central to abolition. Richardson (1998) finds Williams's claims regarding the Industrial Revolution are exaggerated, for profits from the slave trade amounted to less than 1% of domestic investment in Britain. Richardson further challenges claims (by African scholars) that the slave trade caused widespread depopulation and economic distress in Africa-indeed that it caused the "underdevelopment" of Africa. Admitting the horrible suffering of slaves, he notes that many Africans benefited directly because the first stage of the trade was always firmly in the hands of Africans. European slave ships waited at ports to purchase cargoes of people who were captured in the hinterland by African dealers and tribal leaders. Richardson finds that the "terms of trade" (how much the ship owners paid for the slave cargo) moved heavily in favor of the Africans after about 1750. That is, indigenous elites inside West and Central Africa made large and growing profits from slavery, thus increasing their wealth and power.

Economic historian Stanley Engerman finds that even without subtracting the associated costs of the slave trade (e.g., shipping costs, slave mortality, mortality of British people in Africa, defense costs) or reinvestment of profits back into the slave trade, the total profits from the slave trade and of West Indian plantations amounted to less than 5% of the British economy during any year of the Industrial Revolution. Engerman's 5% figure gives as much as possible in terms of benefit of the doubt to the Williams argument, not solely because it does not take into account the associated costs of the slave trade to Britain, but also because it carries the full-employment assumption from economics and holds the gross value of slave trade profits as a direct contribution to Britain's national income. Historian Richard Pares, in an article written before Williams's book, dismisses the influence of wealth generated from the West Indian plantations upon the financing of the Industrial Revolution, stating that whatever substantial flow of investment from West Indian profits into industry there was occurred after emancipation, not before.

# data[].attributes.attachment_link.description
The history of slavery spans many cultures, nationalities, and religions from ancient times to the present day. However the social, economic, and legal positions of slaves have differed vastly in different systems of slavery in different times and places. Slavery occurs relatively rarely among hunter-gatherer populations because it develops under conditions of social stratification.

The Atlantic slave trade or transatlantic slave trade involved the transportation by slave traders of enslaved African people, mainly to the Americas. The slave trade regularly used the triangular trade route and its Middle Passage, and existed from the 16th to the 19th centuries. The vast majority of those who were enslaved and transported in the transatlantic slave trade were people from Central and West Africa, who had been sold by other West Africans, or by half European 'merchant princes' to Western European slave traders (with a small number being captured directly by the slave traders in coastal raids), who brought them to the Americas. Except for the Portuguese, European slave traders generally did not participate in the raids because life expectancy for Europeans in sub-Saharan Africa was less than one year during the period of the slave trade (which was prior to the development of quinine as a treatment for malaria). The South Atlantic and Caribbean economies were particularly dependent on labour for the production of sugarcane and other commodities. This was viewed as crucial by those Western European states which, in the late 17th and 18th centuries, were vying with each other to create overseas empires.

The Portuguese, in the 16th century, were the first to engage in the Atlantic slave trade. In 1526, they completed the first transatlantic slave voyage to Brazil, and other Europeans soon followed. Shipowners regarded the slaves as cargo to be transported to the Americas as quickly and cheaply as possible, there to be sold to work on coffee, tobacco, cocoa, sugar, and cotton plantations, gold and silver mines, rice fields, the construction industry, cutting timber for ships, in skilled labour, and as domestic servants. While the first Africans kidnapped to the English colonies were classified as indentured servants, with a similar legal standing as contract-based workers coming from Britain and Ireland, by the middle of the 17th century, slavery had hardened as a racial caste, with African slaves and their future offspring being legally the property of their owners, as children born to slave mothers were also slaves (partus sequitur ventrem). As property, the people were considered merchandise or units of labour, and were sold at markets with other goods and services.

The major Atlantic slave trading nations, ordered by trade volume, were the Portuguese, the British, the Spanish, the French, the Dutch Empires, and the Danish. Several had established outposts on the African coast where they purchased slaves from local African leaders. These slaves were managed by a factor, who was established on or near the coast to expedite the shipping of slaves to the New World. Slaves were imprisoned in a factory while awaiting shipment. Current estimates are that about 12 million to 12.8 million Africans were shipped across the Atlantic over a span of 400 years, although the number purchased by the traders was considerably higher, as the passage had a high death rate with approximately 1.2-2.4 million dying during the voyage and millions more died in seasoning camps in the Caribbean after arrival to the New World. Millions of slaves also died as a result of slave raids, wars and during transport to the coast for sale to European slave traders. Near the beginning of the 19th century, various governments acted to ban the trade, although illegal smuggling still occurred. In the early 21st century, several governments issued apologies for the transatlantic slave trade.

Background

Atlantic travel

The Atlantic slave trade developed after trade contacts were established between the " Old World" ( Afro-Eurasia) and the " New World" (the Americas). For centuries, tidal currents had made ocean travel particularly difficult and risky for the ships that were then available, and as such there had been very little, if any, maritime contact between the peoples living in these continents. In the 15th century, however, new European developments in seafaring technologies resulted in ships being better equipped to deal with the tidal currents, and could begin traversing the Atlantic Ocean; the Portuguese set up a Navigator's School (although there is much debate about whether it existed and if it did, just what it was). Between 1600 and 1800, approximately 300,000 sailors engaged in the slave trade visited West Africa. In doing so, they came into contact with societies living along the west African coast and in the Americas which they had never previously encountered. Historian Pierre Chaunu termed the consequences of European navigation "disenclavement", with it marking an end of isolation for some societies and an increase in inter-societal contact for most others.

Historian John Thornton noted, "A number of technical and geographical factors combined to make Europeans the most likely people to explore the Atlantic and develop its commerce". He identified these as being the drive to find new and profitable commercial opportunities outside Europe as well as the desire to create an alternative trade network to that controlled by the Muslim Ottoman Empire of the Middle East, which was viewed as a commercial, political and religious threat to European Christendom. In particular, European traders wanted to trade for gold, which could be found in western Africa, and also to find a maritime route to "the Indies" (India), where they could trade for luxury goods such as spices without having to obtain these items from Middle Eastern Islamic traders.

African slavery

Slavery was prevalent in many parts of Africa for many centuries before the beginning of the Atlantic slave trade. There is evidence that enslaved people from some parts of Africa were exported to states in Africa, Europe, and Asia prior to the European colonization of the Americas.

The Atlantic slave trade was not the only slave trade from Africa, although it was the largest in volume and intensity. As Elikia M'bokolo wrote in Le Monde diplomatique:

The African continent was bled of its human resources via all possible routes. Across the Sahara, through the Red Sea, from the Indian Ocean ports and across the Atlantic. At least ten centuries of slavery for the benefit of the Muslim countries (from the ninth to the nineteenth) ... Four million enslaved people exported via the Red Sea, another four million through the Swahili ports of the Indian Ocean, perhaps as many as nine million along the trans-Saharan caravan route, and eleven to twenty million (depending on the author) across the Atlantic Ocean.

According to John K. Thornton, Europeans usually bought enslaved people who were captured in endemic warfare between African states. Some Africans had made a business out of capturing Africans from neighboring ethnic groups or war captives and selling them. A reminder of this practice is documented in the Slave Trade Debates of England in the early 19th century: "All the old writers ... concur in stating not only that wars are entered into for the sole purpose of making slaves, but that they are fomented by Europeans, with a view to that object." People living around the Niger River were transported from these markets to the coast and sold at European trading ports in exchange for muskets and manufactured goods such as cloth or alcohol. However, the European demand for slaves provided a large new market for the already existing trade. While those held in slavery in their own region of Africa might hope to escape, those shipped away had little chance of returning to Africa.

European colonization and slavery in West Africa

Upon discovering new lands through their naval explorations, European colonisers soon began to migrate to and settle in lands outside their native continent. Off the coast of Africa, European migrants, under the directions of the Kingdom of Castile, invaded and colonised the Canary Islands during the 15th century, where they converted much of the land to the production of wine and sugar. Along with this, they also captured native Canary Islanders, the Guanches, to use as slaves both on the Islands and across the Christian Mediterranean.

As historian John Thornton remarked, "the actual motivation for European expansion and for navigational breakthroughs was little more than to exploit the opportunity for immediate profits made by raiding and the seizure or purchase of trade commodities". Using the Canary Islands as a naval base, Europeans, at the time primarily Portuguese traders, began to move their activities down the western coast of Africa, performing raids in which slaves would be captured to be later sold in the Mediterranean. Although initially successful in this venture, "it was not long before African naval forces were alerted to the new dangers, and the Portuguese [raiding] ships began to meet strong and effective resistance", with the crews of several of them being killed by African sailors, whose boats were better equipped at traversing the west African coasts and river systems.

By 1494, the Portuguese king had entered agreements with the rulers of several West African states that would allow trade between their respective peoples, enabling the Portuguese to "tap into" the "well-developed commercial economy in Africa ... without engaging in hostilities". "Peaceful trade became the rule all along the African coast", although there were some rare exceptions when acts of aggression led to violence. For instance, Portuguese traders attempted to conquer the Bissagos Islands in 1535. In 1571 Portugal, supported by the Kingdom of Kongo, took control of the south-western region of Angola in order to secure its threatened economic interest in the area. Although Kongo later joined a coalition in 1591 to force the Portuguese out, Portugal had secured a foothold on the continent that it continued to occupy until the 20th century. Despite these incidences of occasional violence between African and European forces, many African states ensured that any trade went on in their own terms, for instance, imposing custom duties on foreign ships. In 1525, the Kongolese king Afonso I seized a French vessel and its crew for illegally trading on his coast.

Historians have widely debated the nature of the relationship between these African kingdoms and the European traders. The Guyanese historian Walter Rodney (1972) has argued that it was an unequal relationship, with Africans being forced into a "colonial" trade with the more economically developed Europeans, exchanging raw materials and human resources (i.e. slaves) for manufactured goods. He argued that it was this economic trade agreement dating back to the 16th century that led to Africa being underdeveloped in his own time. These ideas were supported by other historians, including Ralph Austen (1987). This idea of an unequal relationship was contested by John Thornton (1998), who argued that "the Atlantic slave trade was not nearly as critical to the African economy as these scholars believed" and that "African manufacturing [at this period] was more than capable of handling competition from preindustrial Europe". However, Anne Bailey, commenting on Thornton's suggestion that Africans and Europeans were equal partners in the Atlantic slave trade, wrote:

16th, 17th and 18th centuries

The Atlantic slave trade is customarily divided into two eras, known as the First and Second Atlantic Systems.

The First Atlantic system was the trade of enslaved Africans to, primarily, South American colonies of the Portuguese and Spanish empires; it accounted for slightly more than 3% of all Atlantic slave trade. It started (on a significant scale) in about 1502 and lasted until 1580 when Portugal was temporarily united with Spain. While the Portuguese were directly involved in trading enslaved peoples, the Spanish empire relied on the asiento system, awarding merchants (mostly from other countries) the license to trade enslaved people to their colonies. During the first Atlantic system, most of these traders were Portuguese, giving them a near-monopoly during the era. Some Dutch, English, and French traders also participated in the slave trade. After the union, Portugal came under Spanish legislation that prohibited it from directly engaging in the slave trade as a carrier. It became a target for the traditional enemies of Spain, losing a large share of the trade to the Dutch, English, and French.

It is estimated that more than half of the entire slave trade took place during the 18th century, with the British, Portuguese and French being the main carriers of nine out of ten slaves abducted in Africa. By the 1690s, the English were shipping the most slaves from West Africa. They maintained this position during the 18th century, becoming the biggest shippers of slaves across the Atlantic. By the 18th century, Angola had become one of the principal sources of the Atlantic slave trade.

Following the British and United States' bans on the African slave trade in 1808, it declined, but the period after still accounted for 28.5% of the total volume of the Atlantic slave trade. Between 1810 and 1860, over 3.5 million slaves were transported, with 850,000 in the 1820s.

A burial ground in Campeche, Mexico, suggests slaves had been brought there not long after Hernán Cortés completed the subjugation of Aztec and Mayan Mexico in the 16th century. The graveyard had been in use from approximately 1550 to the late 17th century.

Triangular trade

The first side of the triangle was the export of goods from Europe to Africa. A number of African kings and merchants took part in the trading of enslaved people from 1440 to about 1833. For each captive, the African rulers would receive a variety of goods from Europe. These included guns, ammunition, and other factory-made goods. The second leg of the triangle exported enslaved Africans across the Atlantic Ocean to the Americas and the Caribbean Islands. The third and final part of the triangle was the return of goods to Europe from the Americas. The goods were the products of slave-labour plantations and included cotton, sugar, tobacco, molasses and rum. Sir John Hawkins, considered the pioneer of the British slave trade, was the first to run the Triangular trade, making a profit at every stop.

Labour and slavery

The Atlantic slave trade was the result of, among other things, labour shortage, itself in turn created by the desire of European colonists to exploit New World land and resources for capital profits. Native peoples were at first utilized as slave labour by Europeans until a large number died from overwork and Old World diseases. Alternative sources of labour, such as indentured servitude, failed to provide a sufficient workforce. Many crops could not be sold for profit, or even grown, in Europe. Exporting crops and goods from the New World to Europe often proved to be more profitable than producing them on the European mainland. A vast amount of labour was needed to create and sustain plantations that required intensive labour to grow, harvest, and process prized tropical crops. Western Africa (part of which became known as "the Slave Coast"), Angola and nearby Kingdoms and later Central Africa, became the source for enslaved people to meet the demand for labour.

The basic reason for the constant shortage of labour was that, with large amounts of cheap land available and lots of landowners searching for workers, free European immigrants were able to become landowners themselves after a relatively short time, thus increasing the need for workers.

Thomas Jefferson attributed the use of slave labour in part to the climate, and the consequent idle leisure afforded by slave labour: "For in a warm climate, no man will labour for himself who can make another labour for him. This is so true, that of the proprietors of slaves a very small proportion indeed are ever seen to labour." In a 2015 paper, economist Elena Esposito argued that the enslavement of Africans in colonial America was attributable to the fact that the American south was sufficiently warm and humid for malaria to thrive; the disease had debilitating effects on the European settlers. Conversely, many enslaved Africans were taken from regions of Africa which hosted particularly potent strains of the disease, so the Africans had already developed natural resistance to malaria. This, Esposito argued, resulted in higher malaria survival rates in the American south among enslaved Africans than among European labourers, making them a more profitable source of labour and encouraging their use.

African participation in the slave trade

Africans played a direct role in the slave trade, selling their captives or prisoners of war to European buyers. The prisoners and captives who were sold were usually from neighbouring or enemy ethnic groups. These captive slaves were considered "other", not part of the people of the ethnic group or "tribe"; African kings held no particular loyalty to them. Sometimes criminals would be sold so that they could no longer commit crimes in that area. Most other slaves were obtained from kidnappings, or through raids that occurred at gunpoint through joint ventures with the Europeans. But some African kings refused to sell any of their captives or criminals. King Jaja of Opobo, a former slave, refused to do any business with the slavers.

According to Ipsen, Africans, namely Ghana, also participated in the slave trade through intermarriage, or , meaning "to set up house". It is derived from the Portuguese word "casar", meaning "to marry". Cassare created political and economic bonds between European and African slave traders. Cassare was a pre-European practice used to integrate the "other" from a differing African tribe. Powerful West African groups used these marriages as an alliance used to strengthen their trade networks with European men by marrying off African women from families with ties to the slave trade. Early on in the Atlantic Slave trade, these marriages were common. The marriages were even performed using African customs, which Europeans did not object to, seeing how important the connections were.

European participation in the slave trade

Although Europeans were the market for slaves, Europeans rarely entered the interior of Africa, due to fear of disease and fierce African resistance. In Africa, convicted criminals could be punished by enslavement, a punishment which became more prevalent as slavery became more lucrative. Since most of these nations did not have a prison system, convicts were often sold or used in the scattered local domestic slave market.

In 1778, Thomas Kitchin estimated that Europeans were bringing an estimated 52,000 slaves to the Caribbean yearly, with the French bringing the most Africans to the French West Indies (13,000 out of the yearly estimate). The Atlantic slave trade peaked in the last two decades of the 18th century, during and following the Kongo Civil War. Wars among tiny states along the Niger River's Igbo-inhabited region and the accompanying banditry also spiked in this period. Another reason for surplus supply of enslaved people was major warfare conducted by expanding states, such as the kingdom of Dahomey, the Oyo Empire, and the Asante Empire.

Slavery in Africa and the New World contrasted

Forms of slavery varied both in Africa and in the New World. In general, slavery in Africa was not heritable-that is, the children of slaves were free-while in the Americas, children of slave mothers were considered born into slavery. This was connected to another distinction: slavery in West Africa was not reserved for racial or religious minorities, as it was in European colonies, although the case was otherwise in places such as Somalia, where Bantus were taken as slaves for the ethnic Somalis.

The treatment of slaves in Africa was more variable than in the Americas. At one extreme, the kings of Dahomey routinely slaughtered slaves in hundreds or thousands in sacrificial rituals, and slaves as human sacrifices were also known in Cameroon. On the other hand, slaves in other places were often treated as part of the family, "adopted children", with significant rights including the right to marry without their masters' permission. Scottish explorer Mungo Park wrote:

In the Americas, slaves were denied the right to marry freely and masters did not generally accept them as equal members of the family. New World slaves were considered the property of their owners, and slaves convicted of revolt or murder were executed.

Slave market regions and participation

There were eight principal areas used by Europeans to buy and ship slaves to the Western Hemisphere. The number of enslaved people sold to the New World varied throughout the slave trade. As for the distribution of slaves from regions of activity, certain areas produced far more enslaved people than others. Between 1650 and 1900, 10.2 million enslaved Africans arrived in the Americas from the following regions in the following proportions:

Although the slave trade was largely global, there was considerable intracontinental slave trade in which 8 million people were enslaved within the African continent. Of those who did move out of Africa, 8 million were forced out of Eastern Africa to be sent to Asia.

African kingdoms of the era

There were over 173 city-states and kingdoms in the African regions affected by the slave trade between 1502 and 1853, when Brazil became the last Atlantic import nation to outlaw the slave trade. Of those 173, no fewer than 68 could be deemed nation states with political and military infrastructures that enabled them to dominate their neighbours. Nearly every present-day nation had a pre-colonial predecessor, sometimes an African empire with which European traders had to barter.

Ethnic groups

The different ethnic groups brought to the Americas closely corresponds to the regions of heaviest activity in the slave trade. Over 45 distinct ethnic groups were taken to the Americas during the trade. Of the 45, the ten most prominent, according to slave documentation of the era are listed below.

The transatlantic slave trade resulted in a vast and as yet still unknown loss of life for African captives both in and outside the Americas. Approximately 1.2-2.4 million Africans died during their transport to the New World. More died soon after their arrival. The number of lives lost in the procurement of slaves remains a mystery but may equal or exceed the number who survived to be enslaved.

Estimates of how many Africans died during the slave trade over the 400-year period of slavery vary. Some estimates put the number "between 100 million and 200 million" to "perhaps as many as 14 million". It is alleged that so many slaves died in the sea that sharks' travel patterns changed to feed off the bodies thrown overboard.

Patrick Manning estimates that about 12 million slaves entered the Atlantic trade between the 16th and 19th century, but about 1.5 million died on board ship. About 10.5 million slaves arrived in the Americas. Besides the slaves who died on the Middle Passage, more Africans likely died during the slave raids in Africa and forced marches to ports. Manning estimates that 4 million died inside Africa after capture, and many more died young. Manning's estimate covers the 12 million who were originally destined for the Atlantic, as well as the 6 million destined for Asian slave markets and the 8 million destined for African markets. Of the slaves shipped to The Americas, the largest share went to Brazil and the Caribbean.

African conflicts

According to Kimani Nehusi, the presence of European slavers affected the way in which the legal code in African societies responded to offenders. Crimes traditionally punishable by some other form of punishment became punishable by enslavement and sale to slave traders. According to David Stannard's American Holocaust, 50% of African deaths occurred in Africa as a result of wars between native kingdoms, which produced the majority of slaves. This includes not only those who died in battles but also those who died as a result of forced marches from inland areas to slave ports on the various coasts. The practice of enslaving enemy combatants and their villages was widespread throughout Western and West Central Africa, although wars were rarely started to procure slaves. The slave trade was largely a by-product of tribal and state warfare as a way of removing potential dissidents after victory or financing future wars. However, some African groups proved particularly adept and brutal at the practice of enslaving, such as Oyo, Benin, Igala, Kaabu, Asanteman, Dahomey, the Aro Confederacy and the Imbangala war bands.

In letters written by the Manikongo, Nzinga Mbemba Afonso, to the King João III of Portugal, he writes that Portuguese merchandise flowing in is what is fueling the trade in Africans. He requests the King of Portugal to stop sending merchandise but should only send missionaries. In one of his letters he writes:

The kings of Dahomey sold war captives into transatlantic slavery; they would otherwise have been killed in a ceremony known as the Annual Customs. As one of West Africa's principal slave states, Dahomey became extremely unpopular with neighbouring peoples. Like the Bambara Empire to the east, the Khasso kingdoms depended heavily on the slave trade for their economy. A family's status was indicated by the number of slaves it owned, leading to wars for the sole purpose of taking more captives. This trade led the Khasso into increasing contact with the European settlements of Africa's west coast, particularly the French. Benin grew increasingly rich during the 16th and 17th centuries on the slave trade with Europe; slaves from enemy states of the interior were sold and carried to the Americas in Dutch and Portuguese ships. The Bight of Benin's shore soon came to be known as the "Slave Coast".

King Gezo of Dahomey said in the 1840s:

In 1807, the UK Parliament passed the Bill that abolished the trading of slaves. The King of Bonny (now in Nigeria) was horrified at the conclusion of the practice:

Port factories

After being marched to the coast for sale, enslaved people were held in large forts called factories. The amount of time in factories varied, but Milton Meltzer states in Slavery: A World History that around 4.5% of deaths attributed to the transatlantic slave trade occurred during this phase. In other words, over 820,000 people are believed to have died in African ports such as Benguela, Elmina, and Bonny, reducing the number of those shipped to 17.5 million.

Atlantic shipment

After being captured and held in the factories, slaves entered the infamous Middle Passage. Meltzer's research puts this phase of the slave trade's overall mortality at 12.5%. Their deaths were the result of brutal treatment and poor care from the time of their capture and throughout their voyage. Around 2.2 million Africans died during these voyages, where they were packed into tight, unsanitary spaces on ships for months at a time. Measures were taken to stem the onboard mortality rate, such as enforced "dancing" (as exercise) above deck and the practice of force-feeding enslaved persons who tried to starve themselves. The conditions on board also resulted in the spread of fatal diseases. Other fatalities were suicides, slaves who escaped by jumping overboard. The slave traders would try to fit anywhere from 350 to 600 slaves on one ship. Before the African slave trade was completely banned by participating nations in 1853, 15.3 million enslaved people had arrived in the Americas.

Raymond L. Cohn, an economics professor whose research has focused on economic history and international migration, has researched the mortality rates among Africans during the voyages of the Atlantic slave trade. He found that mortality rates decreased over the history of the slave trade, primarily because the length of time necessary for the voyage was declining. "In the eighteenth century many slave voyages took at least 2½ months. In the nineteenth century, 2 months appears to have been the maximum length of the voyage, and many voyages were far shorter. Fewer slaves died in the Middle Passage over time mainly because the passage was shorter."

Despite the vast profits of slavery, the ordinary sailors on slave ships were badly paid and subject to harsh discipline. Mortality of around 20% was expected in a ship's crew during the course of a voyage; this was due to disease, flogging, overwork, or slave uprisings. Disease ( malaria or yellow fever) was the most common cause of death among sailors. A high crew mortality rate on the return voyage was in the captain's interests as it reduced the number of sailors who had to be paid on reaching the home port.

The slave trade was hated by many sailors, and those who joined the crews of slave ships often did so through coercion or because they could find no other employment.

Seasoning camps

Meltzer also states that 33% of Africans would have died in the first year at the seasoning camps found throughout the Caribbean. Jamaica held one of the most notorious of these camps. Dysentery was the leading cause of death. Around 5 million Africans died in these camps, reducing the number of survivors to about 10 million.

Notable diseases not originally known as present in Americas before 1492 include those such as smallpox, malaria, bubonic plague, typhus, influenza, measles, diphtheria, yellow fever, and whooping cough. During the Atlantic slave trade following the discovery of the New World, diseases such as these possessed the capability of obliterating populations such as the Natives by the masses as short amount of time as a few weeks or months.

Smallpox was one of the epidemics that surrounded the Atlantic slave trade from the 15th to the 18th centuries. Diseases such as smallpox were known for causing a significant decrease in the indigenous population of the New World. An explanation to aid understanding the logistics behind the extensive population decrease includes the topic of immunity. The native population was not immune to this disease in that they did not have the pathogen required to resist the disease. Those such as the European colonizers and the African slaves brought to the New World, however, did possess this pathogen due to having been previously exposed to smallpox. It was known to be a common illness many underwent as children, which in turn built up their immunity to withstand this disease. As a result of the Native Americans no longer being able to work the lands (as the labor required them to mine gold and silver), European colonizers such as the Portuguese took advantage of their access to regions of the African continent such as Angola from which to extract another source of labor, in which Africans had proven to be prime candidates since they survived this case of the disease - also known as variola intermedius - while the Natives had continued to fall to the various illnesses.

For many diseases, the African and Eurasian population were able to have already acquired immunity- being able to resist an infection- due to prior exposure as children in which they were less likely to receive the same illness again. Upon arrival, these diseases were transmitted to the Native populations who did not have immunity due to no prior exposure having been from climates in which these germs, and pathogens surrounding these diseases were not common. Having been exposed to the illness as an adult, some effects would prove to be more enhanced than if they were to be at an adolescent age.

Levels and extent of immunity varies from disease to disease. For smallpox and measles for example, those who survive are equipped with the cellular immunity to combat the disease for the rest of their life in that they cannot contract the disease again. There are also diseases in which immunity does not guarantee that an individual is not susceptible to becoming reinfected.

Inoculation

As epidemiology advances, causes and effective treatments are being discovered to combat historically destructive diseases such as syphilis-which in today can be treated with simple antibiotics such as penicillin and other medications that can inhibit and rid the body of harmful bacteria.

European competition

The trade of enslaved Africans in the Atlantic has its origins in the explorations of Portuguese mariners down the coast of West Africa in the 15th century. Before that, contact with African slave markets was made to ransom Portuguese who had been captured by the intense North African Barbary pirate attacks on Portuguese ships and coastal villages, frequently leaving them depopulated. The first Europeans to use enslaved Africans in the New World were the Spaniards, who sought auxiliaries for their conquest expeditions and labourers on islands such as Cuba and Hispaniola. The alarming decline in the native population had spurred the first royal laws protecting them (Laws of Burgos, 1512-13). The first enslaved Africans arrived in Hispaniola in 1501. After Portugal had succeeded in establishing sugar plantations ( engenhos) in northern Brazil c. 1545, Portuguese merchants on the West African coast began to supply enslaved Africans to the sugar planters. While at first these planters had relied almost exclusively on the native Tupani for slave labour, after 1570 they began importing Africans, as a series of epidemics had decimated the already destabilized Tupani communities. By 1630, Africans had replaced the Tupani as the largest contingent of labour on Brazilian sugar plantations. This ended the European medieval household tradition of slavery, resulted in Brazil's receiving the most enslaved Africans, and revealed sugar cultivation and processing as the reason that roughly 84% of these Africans were shipped to the New World.

As Britain rose in naval power and settled continental North America and some islands of the West Indies, they became the leading slave traders. At one stage the trade was the monopoly of the Royal Africa Company, operating out of London. But, following the loss of the company's monopoly in 1689, Bristol and Liverpool merchants became increasingly involved in the trade. By the late 17th century, one out of every four ships that left Liverpool harbour was a slave trading ship. Much of the wealth on which the city of Manchester, and surrounding towns, was built in the late 18th century, and for much of the 19th century, was based on the processing of slave-picked cotton and manufacture of cloth. Other British cities also profited from the slave trade. Birmingham, the largest gun-producing town in Britain at the time, supplied guns to be traded for slaves. 75% of all sugar produced in the plantations was sent to London, and much of it was consumed in the highly lucrative coffee houses there.

New World destinations

The first slaves to arrive as part of a labour force in the New World reached the island of Hispaniola (now Haiti and the Dominican Republic) in 1502. Cuba received its first four slaves in 1513. Jamaica received its first shipment of 4000 slaves in 1518. Slave exports to Honduras and Guatemala started in 1526.

The first enslaved Africans to reach what would become the United States arrived in July 1526 as part of a Spanish attempt to colonize San Miguel de Gualdape. By November the 300 Spanish colonists were reduced to 100, and their slaves from 100 to 70. The enslaved people revolted in 1526 and joined a nearby Native American tribe, while the Spanish abandoned the colony altogether (1527). The area of the future Colombia received its first enslaved people in 1533. El Salvador, Costa Rica and Florida began their stints in the slave trade in 1541, 1563 and 1581, respectively.

The 17th century saw an increase in shipments. Africans were brought to Point Comfort - several miles downriver from the English colony of Jamestown, Virginia - in 1619. The first kidnapped Africans in English North America were classed as indentured servants and freed after seven years. Virginia law codified chattel slavery in 1656, and in 1662 the colony adopted the principle of partus sequitur ventrem, which classified children of slave mothers as slaves, regardless of paternity. Irish immigrants took slaves to Montserrat in 1651, and in 1655 slaves were shipped to Belize.

Recently bought slaves in Brazil on their way to the farms of the landowners who bought them c. 1830.

Economics of slavery

In France in the 18th century, returns for investors in plantations averaged around 6%; as compared to 5% for most domestic alternatives, this represented a 20% profit advantage. Risks-maritime and commercial-were important for individual voyages. Investors mitigated it by buying small shares of many ships at the same time. In that way, they were able to diversify a large part of the risk away. Between voyages, ship shares could be freely sold and bought.

By far the most financially profitable West Indian colonies in 1800 belonged to the United Kingdom. After entering the sugar colony business late, British naval supremacy and control over key islands such as Jamaica, Trinidad, the Leeward Islands and Barbados and the territory of British Guiana gave it an important edge over all competitors; while many British did not make gains, a handful of individuals made small fortunes. This advantage was reinforced when France lost its most important colony, St. Domingue (western Hispaniola, now Haiti), to a slave revolt in 1791 and supported revolts against its rival Britain, in the name of liberty after the 1793 French revolution. Before 1791, British sugar had to be protected to compete against cheaper French sugar.

Effect on the economy of West Africa

No scholars dispute the harm done to the enslaved people but the effect of the trade on African societies is much debated, due to the apparent influx of goods to Africans. Proponents of the slave trade, such as Archibald Dalzel, argued that African societies were robust and not much affected by the trade. In the 19th century, European abolitionists, most prominently Dr. David Livingstone, took the opposite view, arguing that the fragile local economy and societies were being severely harmed by the trade.

Because the negative effects of slavery on the economies of Africa have been well documented, namely the significant decline in population, some African rulers likely saw an economic benefit from trading their subjects with European slave traders. With the exception of Portuguese-controlled Angola, coastal African leaders "generally controlled access to their coasts, and were able to prevent direct enslavement of their subjects and citizens". Thus, as African scholar John Thornton argues, African leaders who allowed the continuation of the slave trade likely derived an economic benefit from selling their subjects to Europeans. The Kingdom of Benin, for instance, participated in the African slave trade, at will, from 1715 to 1735, surprising Dutch traders, who had not expected to buy slaves in Benin. The benefit derived from trading slaves for European goods was enough to make the Kingdom of Benin rejoin the trans-Atlantic slave trade after centuries of non-participation. Such benefits included military technology (specifically guns and gunpowder), gold, or simply maintaining amicable trade relationships with European nations. The slave trade was, therefore, a means for some African elites to gain economic advantages. Historian Walter Rodney estimates that by c.1770, the King of Dahomey was earning an estimated £250,000 per year by selling captive African soldiers and enslaved people to the European slave-traders. Many West African countries also already had a tradition of holding slaves, which was expanded into trade with Europeans.

The Atlantic trade brought new crops to Africa and also more efficient currencies which were adopted by the West African merchants. This can be interpreted as an institutional reform which reduced the cost of doing business. But the developmental benefits were limited as long as the business including slaving.

Both Thornton and Fage contend that while African political elite may have ultimately benefited from the slave trade, their decision to participate may have been influenced more by what they could lose by not participating. In Fage's article "Slavery and the Slave Trade in the Context of West African History", he notes that for West Africans "...there were really few effective means of mobilizing labour for the economic and political needs of the state" without the slave trade.

Effects on the British economy

Other researchers and historians have strongly contested what has come to be referred to as the "Williams thesis" in academia. David Richardson has concluded that the profits from the slave trade amounted to less than 1% of domestic investment in Britain. Economic historian Stanley Engerman finds that even without subtracting the associated costs of the slave trade (e.g., shipping costs, slave mortality, mortality of British people in Africa, defense costs) or reinvestment of profits back into the slave trade, the total profits from the slave trade and of West Indian plantations amounted to less than 5% of the British economy during any year of the Industrial Revolution. Engerman's 5% figure gives as much as possible in terms of benefit of the doubt to the Williams argument, not solely because it does not take into account the associated costs of the slave trade to Britain, but also because it carries the full-employment assumption from economics and holds the gross value of slave trade profits as a direct contribution to Britain's national income. Historian Richard Pares, in an article written before Williams' book, dismisses the influence of wealth generated from the West Indian plantations upon the financing of the Industrial Revolution, stating that whatever substantial flow of investment from West Indian profits into industry there occurred after emancipation, not before. However, each of these works focus primarily on the slave trade or the Industrial Revolution, and not the main body of the Williams thesis, which was on sugar and slavery itself. Therefore, they do not refute the main body of the Williams thesis.

Seymour Drescher and Robert Anstey argue the slave trade remained profitable until the end, and that moralistic reform, not economic incentive, was primarily responsible for abolition. They say slavery remained profitable in the 1830s because of innovations in agriculture. However, Drescher's Econocide wraps up its study in 1823, and does not address the majority of the Williams thesis, which covers the decline of the sugar plantations after 1823, the emancipation of the slaves in the 1830s, and the subsequent abolition of sugar duties in the 1840s. These arguments do not refute the main body of the Williams thesis, which presents economic data to show that the slave trade was minor compared to the wealth generated by sugar and slavery itself in the British Caribbean.

Karl Marx in his influential economic history of capitalism Das Kapital wrote that "...the turning of Africa into a warren for the commercial hunting of black-skins, signaled the rosy dawn of the era of capitalist production". He argued that the slave trade was part of what he termed the "primitive accumulation" of capital, the 'non-capitalist' accumulation of wealth that preceded and created the financial conditions for Britain's industrialisation.

Demographics

The demographic effects of the slave trade is a controversial and highly debated issue. Although scholars such as Paul Adams and Erick D. Langer have estimated that sub-Saharan Africa represented about 18 percent of the world's population in 1600 and only 6 percent in 1900, the reasons for this demographic shift have been the subject of much debate. In addition to the depopulation Africa experienced because of the slave trade, African nations were left with severely imbalanced gender ratios, with females comprising up to 65 percent of the population in hard-hit areas such as Angola. Moreover, many scholars (such as Barbara N. Ramusack) have suggested a link between the prevalence of prostitution in Africa today with the temporary marriages that were enforced during the course of the slave trade.

Walter Rodney argued that the export of so many people had been a demographic disaster which left Africa permanently disadvantaged when compared to other parts of the world, and it largely explains the continent's continued poverty. He presented numbers showing that Africa's population stagnated during this period, while those of Europe and Asia grew dramatically. According to Rodney, all other areas of the economy were disrupted by the slave trade as the top merchants abandoned traditional industries in order to pursue slaving, and the lower levels of the population were disrupted by the slaving itself.

Other scholars accused Walter Rodney of mischaracterizing the trade between Africans and Europeans. They argue that Africans, or more accurately African elites, deliberately let European traders join in an already large trade in enslaved people and that they were not patronized.

As Joseph E. Inikori argues, the history of the region shows that the effects were still quite deleterious. He argues that the African economic model of the period was very different from the European model, and could not sustain such population losses. Population reductions in certain areas also led to widespread problems. Inikori also notes that after the suppression of the slave trade Africa's population almost immediately began to rapidly increase, even prior to the introduction of modern medicines.

Legacy of racism

Walter Rodney states

Similarly, John Darwin writes "The rapid conversion from white indentured labour to black slavery... made the English Caribbean a frontier of civility where English (later British) ideas about race and slave labour were ruthlessly adapted to local self-interest...Indeed, the root justification for the system of slavery and the savage apparatus of coercion on which its preservation depended was the ineradicable barbarism of the slave population, a product, it was argued, of its African origins".

End of the Atlantic slave trade

In Britain, America, Portugal and in parts of Europe, opposition developed against the slave trade. Davis says that abolitionists assumed "that an end to slave imports would lead automatically to the amelioration and gradual abolition of slavery". In Britain and America, opposition to the trade was led by the Religious Society of Friends (Quakers) and establishment Evangelicals such as William Wilberforce. Many people joined the movement and they began to protest against the trade, but they were opposed by the owners of the colonial holdings. Following Lord Mansfield's decision in 1772, many abolitionists and slave-holders believed that slaves became free upon entering the British isles. However, in reality slavery continued in Britain right up to abolition in the 1830s. The Mansfield ruling on Somerset v Stewart only decreed that a slave could not be transported out of England against his will.

Under the leadership of Thomas Jefferson, the new state of Virginia in 1778 became the first state and one of the first jurisdictions anywhere to stop the importation of slaves for sale; it made it a crime for traders to bring in slaves from out of state or from overseas for sale; migrants from other states were allowed to bring their own slaves. The new law freed all slaves brought in illegally after its passage and imposed heavy fines on violators. All the other states followed suit, although South Carolina reopened the slave trade in 1803.

Denmark, which had been active in the slave trade, was the first country to ban the trade through legislation in 1792, which took effect in 1803. Britain banned the slave trade in 1807, imposing stiff fines for any slave found aboard a British ship ( see Slave Trade Act 1807). The Royal Navy moved to stop other nations from continuing the slave trade and declared that slaving was equal to piracy and was punishable by death. The United States Congress passed the Slave Trade Act of 1794, which prohibited the building or outfitting of ships in the U.S. for use in the slave trade. The U.S. Constitution barred a federal prohibition on importing slaves for 20 years; at that time the Act Prohibiting Importation of Slaves prohibited imports on the first day the Constitution permitted: January 1, 1808.

British abolitionism

On 22 February 1807, the House of Commons passed a motion 283 votes to 16 to abolish the Atlantic slave trade. Hence, the slave trade was abolished, but not the still-economically viable institution of slavery itself, which provided Britain's most lucrative import at the time, sugar. Abolitionists did not move against sugar and slavery itself until after the sugar industry went into terminal decline after 1823.

At the same time, although without mutual consultation, the United States abolished the slave trade the same year, but not its internal slave trade which became the dominant character in American slavery until the 1860s. In 1805 the British Order-in-Council had restricted the importation of slaves into colonies that had been captured from France and the Netherlands. Britain continued to press other nations to end its trade; in 1810 an Anglo-Portuguese treaty was signed whereby Portugal agreed to restrict its trade into its colonies; an 1813 Anglo-Swedish treaty whereby Sweden outlawed its slave trade; the Treaty of Paris 1814 where France agreed with Britain that the trade is "repugnant to the principles of natural justice" and agreed to abolish the slave trade in five years; the 1814 Anglo-Netherlands treaty where the Dutch outlawed its slave trade.

Castlereagh and Palmerston's diplomacy

Abolitionist opinion in Britain was strong enough in 1807 to abolish the slave trade in all British possessions, although slavery itself persisted in the colonies until 1833. Abolitionists after 1807 focused on international agreements to abolish the slave trade. Foreign Minister Castlereagh switched his position and became a strong supporter of the movement. Britain arrange treaties with Portugal Sweden and Denmark, 1810-1814, whereby they agreed to end or restrict their trading. These were preliminary to the Congress of Vienna negotiations that Castlereagh dominated and which resulted in a general declaration condemning the slave trade. The problem was that the treaties and declarations were hard to enforce, given the very high profits available to private interests. As Foreign Minister, Castlereagh cooperated with senior officials to use the Royal Navy to detect and capture slave ships. He used diplomacy to make search and seize agreements with all the government whose ships were trading. There was serious friction with the United States, where the southern slave interest was politically powerful. Washington recoiled at British policing of the high seas. Spain France and Portugal also relied on the international slave trade to supply their colonial plantations. As more and more diplomatic arrangements were made by Castlereagh, the owners of slave ships started flying false flags of nations that had not agreed, especially the United States. It was illegal under American law for American ships to engage in the slave trade, but the idea of Britain enforcing American laws was unacceptable to Washington. Lord Palmerston and other British foreign ministers continued the Castlereagh policies. Eventually, in 1842 in 1845, an arrangement was reached between London and Washington. With the arrival of a staunchly anti-slavery government in Washington in 1861, the Atlantic slave trade was doomed. In the long run, Castlereagh's strategy on how to stifle the slave trade proved successful.

The Royal Navy's West Africa Squadron, established in 1808, grew by 1850 to a force of some 25 vessels, which were tasked with combating slavery along the African coast. Between 1807 and 1860, the Royal Navy's Squadron seized approximately 1,600 ships involved in the slave trade and freed 150,000 Africans who were aboard these vessels. Several hundred slaves a year were transported by the navy to the British colony of Sierra Leone, where they were made to serve as "apprentices" in the colonial economy until the Slavery Abolition Act 1833.

Last slave ship to the United States

The last recorded slave ship to land on U.S. soil was the Clotilde, which in 1859 illegally smuggled a number of Africans into the town of Mobile, Alabama. The Africans on board were sold as slaves; however, slavery in the U.S. was abolished five years later following the end of the American Civil War in 1865. The last survivor of the voyage was Cudjoe Lewis, who died in 1935. The last country to ban the Atlantic slave trade was Brazil in 1831. However, a vibrant illegal trade continued to ship large numbers of enslaved people to Brazil and also to Cuba until the 1860s, when British enforcement and further diplomacy finally ended the Atlantic slave trade. In 1870, Portugal ended the last trade route with the Americas, where the last country to import slaves was Brazil. In Brazil, however, slavery itself was not ended until 1888, making it the last country in the Americas to end involuntary servitude.

Economic motivation to end the slave trade

The historian Walter Rodney contends that it was a decline in the profitability of the triangular trades that made it possible for certain basic human sentiments to be asserted at the decision-making level in a number of European countries-Britain being the most crucial because it was the greatest carrier of African captives across the Atlantic. Rodney states that changes in productivity, technology, and patterns of exchange in Europe and the Americas informed the decision by the British to end their participation in the trade in 1807. In 1809 President James Madison outlawed the slave trade with the United States.

Nevertheless, Michael Hardt and Antonio Negri argue that it was neither a strictly economic nor moral matter. First, because slavery was (in practice) still beneficial to capitalism, providing not only an influx of capital but also disciplining hardship into workers (a form of "apprenticeship" to the capitalist industrial plant). The more "recent" argument of a "moral shift" (the basis of the previous lines of this article) is described by Hardt and Negri as an "ideological" apparatus in order to eliminate the sentiment of guilt in western society. Although moral arguments did play a secondary role, they usually had major resonance when used as a strategy to undercut competitors' profits. This argument holds that Eurocentric history has been blind to the most important element in this fight for emancipation, precisely, the constant revolt and the antagonism of slaves' revolts. The most important of those being the Haitian Revolution. The shock of this revolution in 1804, certainly introduces an essential political argument into the end of the slave trade, which happened only three years later.

However, both James Stephen (British politician) and Henry Brougham, 1st Baron Brougham and Vaux wrote that the slave trade could be abolished for the benefit of the British colonies, and the latter's pamphlet was often used in parliamentary debates in favour of abolition. William Pitt the Younger argued on the basis of these writings that the British colonies would be better off, in economics as well as security, if the trade was abolished. As a result, according to historian Christer Petley, abolitionists argued, and even some absentee plantation owners accepted, that the trade could be abolished "without substantial damage to the plantation economy". William Grenville, 1st Baron Grenville argued that "the slave population of the colonies could be maintained without it." Petley points out that government took the decision to abolish the trade "with the express intention of improving, not destroying, the still-lucrative plantation economy of the British West Indies."

African diaspora

The African diaspora which was created via slavery has been a complex interwoven part of American history and culture. In the United States, the success of Alex Haley's book Roots: The Saga of an American Family, published in 1976, and , the subsequent television miniseries based upon it, broadcast on the ABC network in January 1977, led to an increased interest and appreciation of African heritage amongst the African-American community. The influence of these led many African Americans to begin researching their family histories and making visits to West Africa. In turn, a tourist industry grew up to supply them. One notable example of this is through the Roots Homecoming Festival held annually in the Gambia, in which rituals are held through which African Americans can symbolically "come home" to Africa. Issues of dispute have however developed between African Americans and African authorities over how to display historic sites that were involved in the Atlantic slave trade, with prominent voices in the former criticising the latter for not displaying such sites sensitively, but instead treating them as a commercial enterprise.

"Back to Africa"

Rastafari movement

In 1998, UNESCO designated 23 August as International Day for the Remembrance of the Slave Trade and its Abolition. Since then there have been a number of events recognizing the effects of slavery.

At the 2001 World Conference Against Racism in Durban, South Africa, African nations demanded a clear apology for slavery from the former slave-trading countries. Some nations were ready to express an apology, but the opposition, mainly from the United Kingdom, Portugal, Spain, the Netherlands, and the United States blocked attempts to do so. A fear of monetary compensation might have been one of the reasons for the opposition. As of 2009, efforts are underway to create a UN Slavery Memorial as a permanent remembrance of the victims of the Atlantic slave trade.

In 1999, President Mathieu Kerekou of Benin (formerly the Kingdom of Dahomey) issued a national apology for the role Africans played in the Atlantic slave trade. Luc Gnacadja, minister of environment and housing for Benin, later said: "The slave trade is a shame, and we do repent for it." Researchers estimate that 3 million slaves were exported out of the Slave Coast bordering the Bight of Benin.

Netherlands

United Kingdom

On 27 November 2006, British Prime Minister Tony Blair made a partial apology for Britain's role in the African slavery trade. However African rights activists denounced it as "empty rhetoric" that failed to address the issue properly. They feel his apology stopped shy to prevent any legal retort. Blair again apologized on March 14, 2007.

On 24 August 2007, Ken Livingstone ( Mayor of London) apologized publicly for London's role in the slave trade. "You can look across there to see the institutions that still have the benefit of the wealth they created from slavery," he said, pointing towards the financial district, before breaking down in tears. He said that London was still tainted by the horrors of slavery. Jesse Jackson praised Mayor Livingstone and added that reparations should be made.

United States

On 24 February 2007, the Virginia General Assembly passed House Joint Resolution Number 728 acknowledging "with profound regret the involuntary servitude of Africans and the exploitation of Native Americans, and call for reconciliation among all Virginians". With the passing of that resolution, Virginia became the first of the 50 United States to acknowledge through the state's governing body their state's involvement in slavery. The passing of this resolution came on the heels of the 400th-anniversary celebration of the city of Jamestown, Virginia, which was the first permanent English colony to survive in what would become the United States. Jamestown is also recognized as one of the first slave ports of the American colonies. On 31 May 2007, the Governor of Alabama, Bob Riley, signed a resolution expressing "profound regret" for Alabama's role in slavery and apologizing for slavery's wrongs and lingering effects. Alabama is the fourth state to pass a slavery apology, following votes by the legislatures in Maryland, Virginia, and North Carolina.

On 30 July 2008, the United States House of Representatives passed a resolution apologizing for American slavery and subsequent discriminatory laws. The language included a reference to the "fundamental injustice, cruelty, brutality and inhumanity of slavery and Jim Crow" segregation. On 18 June 2009, the United States Senate issued an apologetic statement decrying the "fundamental injustice, cruelty, brutality, and inhumanity of slavery". The news was welcomed by President Barack Obama.

The Atlantic slave trade or transatlantic slave trade involved the transportation by slave traders of enslaved African people, mainly to the Americas. The slave trade regularly used the triangular trade route and its Middle Passage, and existed from the 16th to the 19th centuries. The vast majority of those who were enslaved and transported in the transatlantic slave trade were people from Central and West Africa, who had been sold by other West Africans, or by half European 'merchant princes' to Western European slave traders (with a small number being captured directly by the slave traders in coastal raids), who brought them to the Americas. Except for the Portuguese, European slave traders generally did not participate in the raids because life expectancy for Europeans in sub-Saharan Africa was less than one year during the period of the slave trade (which was prior to the development of quinine as a treatment for malaria). The South Atlantic and Caribbean economies were particularly dependent on labour for the production of sugarcane and other commodities. This was viewed as crucial by those Western European states which, in the late 17th and 18th centuries, were vying with each other to create overseas empires.

The Portuguese, in the 16th century, were the first to engage in the Atlantic slave trade. In 1526, they completed the first transatlantic slave voyage to Brazil, and other Europeans soon followed. Shipowners regarded the slaves as cargo to be transported to the Americas as quickly and cheaply as possible, there to be sold to work on coffee, tobacco, cocoa, sugar, and cotton plantations, gold and silver mines, rice fields, the construction industry, cutting timber for ships, in skilled labour, and as domestic servants. While the first Africans kidnapped to the English colonies were classified as indentured servants, with a similar legal standing as contract-based workers coming from Britain and Ireland, by the middle of the 17th century, slavery had hardened as a racial caste, with African slaves and their future offspring being legally the property of their owners, as children born to slave mothers were also slaves (partus sequitur ventrem). As property, the people were considered merchandise or units of labour, and were sold at markets with other goods and services.

The major Atlantic slave trading nations, ordered by trade volume, were the Portuguese, the British, the Spanish, the French, the Dutch Empires, and the Danish. Several had established outposts on the African coast where they purchased slaves from local African leaders. These slaves were managed by a factor, who was established on or near the coast to expedite the shipping of slaves to the New World. Slaves were imprisoned in a factory while awaiting shipment. Current estimates are that about 12 million to 12.8 million Africans were shipped across the Atlantic over a span of 400 years, although the number purchased by the traders was considerably higher, as the passage had a high death rate with approximately 1.2-2.4 million dying during the voyage and millions more died in seasoning camps in the Caribbean after arrival to the New World. Millions of slaves also died as a result of slave raids, wars and during transport to the coast for sale to European slave traders. Near the beginning of the 19th century, various governments acted to ban the trade, although illegal smuggling still occurred. In the early 21st century, several governments issued apologies for the transatlantic slave trade.

Background

Atlantic travel

The Atlantic slave trade developed after trade contacts were established between the " Old World" ( Afro-Eurasia) and the " New World" (the Americas). For centuries, tidal currents had made ocean travel particularly difficult and risky for the ships that were then available, and as such there had been very little, if any, maritime contact between the peoples living in these continents. In the 15th century, however, new European developments in seafaring technologies resulted in ships being better equipped to deal with the tidal currents, and could begin traversing the Atlantic Ocean; the Portuguese set up a Navigator's School (although there is much debate about whether it existed and if it did, just what it was). Between 1600 and 1800, approximately 300,000 sailors engaged in the slave trade visited West Africa. In doing so, they came into contact with societies living along the west African coast and in the Americas which they had never previously encountered. Historian Pierre Chaunu termed the consequences of European navigation "disenclavement", with it marking an end of isolation for some societies and an increase in inter-societal contact for most others.

Historian John Thornton noted, "A number of technical and geographical factors combined to make Europeans the most likely people to explore the Atlantic and develop its commerce". He identified these as being the drive to find new and profitable commercial opportunities outside Europe as well as the desire to create an alternative trade network to that controlled by the Muslim Ottoman Empire of the Middle East, which was viewed as a commercial, political and religious threat to European Christendom. In particular, European traders wanted to trade for gold, which could be found in western Africa, and also to find a maritime route to "the Indies" (India), where they could trade for luxury goods such as spices without having to obtain these items from Middle Eastern Islamic traders.

African slavery

Slavery was prevalent in many parts of Africa for many centuries before the beginning of the Atlantic slave trade. There is evidence that enslaved people from some parts of Africa were exported to states in Africa, Europe, and Asia prior to the European colonization of the Americas.

The Atlantic slave trade was not the only slave trade from Africa, although it was the largest in volume and intensity. As Elikia M'bokolo wrote in Le Monde diplomatique:

The African continent was bled of its human resources via all possible routes. Across the Sahara, through the Red Sea, from the Indian Ocean ports and across the Atlantic. At least ten centuries of slavery for the benefit of the Muslim countries (from the ninth to the nineteenth) ... Four million enslaved people exported via the Red Sea, another four million through the Swahili ports of the Indian Ocean, perhaps as many as nine million along the trans-Saharan caravan route, and eleven to twenty million (depending on the author) across the Atlantic Ocean.

According to John K. Thornton, Europeans usually bought enslaved people who were captured in endemic warfare between African states. Some Africans had made a business out of capturing Africans from neighboring ethnic groups or war captives and selling them. A reminder of this practice is documented in the Slave Trade Debates of England in the early 19th century: "All the old writers ... concur in stating not only that wars are entered into for the sole purpose of making slaves, but that they are fomented by Europeans, with a view to that object." People living around the Niger River were transported from these markets to the coast and sold at European trading ports in exchange for muskets and manufactured goods such as cloth or alcohol. However, the European demand for slaves provided a large new market for the already existing trade. While those held in slavery in their own region of Africa might hope to escape, those shipped away had little chance of returning to Africa.

European colonization and slavery in West Africa

Upon discovering new lands through their naval explorations, European colonisers soon began to migrate to and settle in lands outside their native continent. Off the coast of Africa, European migrants, under the directions of the Kingdom of Castile, invaded and colonised the Canary Islands during the 15th century, where they converted much of the land to the production of wine and sugar. Along with this, they also captured native Canary Islanders, the Guanches, to use as slaves both on the Islands and across the Christian Mediterranean.

As historian John Thornton remarked, "the actual motivation for European expansion and for navigational breakthroughs was little more than to exploit the opportunity for immediate profits made by raiding and the seizure or purchase of trade commodities". Using the Canary Islands as a naval base, Europeans, at the time primarily Portuguese traders, began to move their activities down the western coast of Africa, performing raids in which slaves would be captured to be later sold in the Mediterranean. Although initially successful in this venture, "it was not long before African naval forces were alerted to the new dangers, and the Portuguese [raiding] ships began to meet strong and effective resistance", with the crews of several of them being killed by African sailors, whose boats were better equipped at traversing the west African coasts and river systems.

By 1494, the Portuguese king had entered agreements with the rulers of several West African states that would allow trade between their respective peoples, enabling the Portuguese to "tap into" the "well-developed commercial economy in Africa ... without engaging in hostilities". "Peaceful trade became the rule all along the African coast", although there were some rare exceptions when acts of aggression led to violence. For instance, Portuguese traders attempted to conquer the Bissagos Islands in 1535. In 1571 Portugal, supported by the Kingdom of Kongo, took control of the south-western region of Angola in order to secure its threatened economic interest in the area. Although Kongo later joined a coalition in 1591 to force the Portuguese out, Portugal had secured a foothold on the continent that it continued to occupy until the 20th century. Despite these incidences of occasional violence between African and European forces, many African states ensured that any trade went on in their own terms, for instance, imposing custom duties on foreign ships. In 1525, the Kongolese king Afonso I seized a French vessel and its crew for illegally trading on his coast.

Historians have widely debated the nature of the relationship between these African kingdoms and the European traders. The Guyanese historian Walter Rodney (1972) has argued that it was an unequal relationship, with Africans being forced into a "colonial" trade with the more economically developed Europeans, exchanging raw materials and human resources (i.e. slaves) for manufactured goods. He argued that it was this economic trade agreement dating back to the 16th century that led to Africa being underdeveloped in his own time. These ideas were supported by other historians, including Ralph Austen (1987). This idea of an unequal relationship was contested by John Thornton (1998), who argued that "the Atlantic slave trade was not nearly as critical to the African economy as these scholars believed" and that "African manufacturing [at this period] was more than capable of handling competition from preindustrial Europe". However, Anne Bailey, commenting on Thornton's suggestion that Africans and Europeans were equal partners in the Atlantic slave trade, wrote:

16th, 17th and 18th centuries

The Atlantic slave trade is customarily divided into two eras, known as the First and Second Atlantic Systems.

The First Atlantic system was the trade of enslaved Africans to, primarily, South American colonies of the Portuguese and Spanish empires; it accounted for slightly more than 3% of all Atlantic slave trade. It started (on a significant scale) in about 1502 and lasted until 1580 when Portugal was temporarily united with Spain. While the Portuguese were directly involved in trading enslaved peoples, the Spanish empire relied on the asiento system, awarding merchants (mostly from other countries) the license to trade enslaved people to their colonies. During the first Atlantic system, most of these traders were Portuguese, giving them a near-monopoly during the era. Some Dutch, English, and French traders also participated in the slave trade. After the union, Portugal came under Spanish legislation that prohibited it from directly engaging in the slave trade as a carrier. It became a target for the traditional enemies of Spain, losing a large share of the trade to the Dutch, English, and French.

It is estimated that more than half of the entire slave trade took place during the 18th century, with the British, Portuguese and French being the main carriers of nine out of ten slaves abducted in Africa. By the 1690s, the English were shipping the most slaves from West Africa. They maintained this position during the 18th century, becoming the biggest shippers of slaves across the Atlantic. By the 18th century, Angola had become one of the principal sources of the Atlantic slave trade.

Following the British and United States' bans on the African slave trade in 1808, it declined, but the period after still accounted for 28.5% of the total volume of the Atlantic slave trade. Between 1810 and 1860, over 3.5 million slaves were transported, with 850,000 in the 1820s.

A burial ground in Campeche, Mexico, suggests slaves had been brought there not long after Hernán Cortés completed the subjugation of Aztec and Mayan Mexico in the 16th century. The graveyard had been in use from approximately 1550 to the late 17th century.

Triangular trade

The first side of the triangle was the export of goods from Europe to Africa. A number of African kings and merchants took part in the trading of enslaved people from 1440 to about 1833. For each captive, the African rulers would receive a variety of goods from Europe. These included guns, ammunition, and other factory-made goods. The second leg of the triangle exported enslaved Africans across the Atlantic Ocean to the Americas and the Caribbean Islands. The third and final part of the triangle was the return of goods to Europe from the Americas. The goods were the products of slave-labour plantations and included cotton, sugar, tobacco, molasses and rum. Sir John Hawkins, considered the pioneer of the British slave trade, was the first to run the Triangular trade, making a profit at every stop.

Labour and slavery

The Atlantic slave trade was the result of, among other things, labour shortage, itself in turn created by the desire of European colonists to exploit New World land and resources for capital profits. Native peoples were at first utilized as slave labour by Europeans until a large number died from overwork and Old World diseases. Alternative sources of labour, such as indentured servitude, failed to provide a sufficient workforce. Many crops could not be sold for profit, or even grown, in Europe. Exporting crops and goods from the New World to Europe often proved to be more profitable than producing them on the European mainland. A vast amount of labour was needed to create and sustain plantations that required intensive labour to grow, harvest, and process prized tropical crops. Western Africa (part of which became known as "the Slave Coast"), Angola and nearby Kingdoms and later Central Africa, became the source for enslaved people to meet the demand for labour.

The basic reason for the constant shortage of labour was that, with large amounts of cheap land available and lots of landowners searching for workers, free European immigrants were able to become landowners themselves after a relatively short time, thus increasing the need for workers.

Thomas Jefferson attributed the use of slave labour in part to the climate, and the consequent idle leisure afforded by slave labour: "For in a warm climate, no man will labour for himself who can make another labour for him. This is so true, that of the proprietors of slaves a very small proportion indeed are ever seen to labour." In a 2015 paper, economist Elena Esposito argued that the enslavement of Africans in colonial America was attributable to the fact that the American south was sufficiently warm and humid for malaria to thrive; the disease had debilitating effects on the European settlers. Conversely, many enslaved Africans were taken from regions of Africa which hosted particularly potent strains of the disease, so the Africans had already developed natural resistance to malaria. This, Esposito argued, resulted in higher malaria survival rates in the American south among enslaved Africans than among European labourers, making them a more profitable source of labour and encouraging their use.

African participation in the slave trade

Africans played a direct role in the slave trade, selling their captives or prisoners of war to European buyers. The prisoners and captives who were sold were usually from neighbouring or enemy ethnic groups. These captive slaves were considered "other", not part of the people of the ethnic group or "tribe"; African kings held no particular loyalty to them. Sometimes criminals would be sold so that they could no longer commit crimes in that area. Most other slaves were obtained from kidnappings, or through raids that occurred at gunpoint through joint ventures with the Europeans. But some African kings refused to sell any of their captives or criminals. King Jaja of Opobo, a former slave, refused to do any business with the slavers.

According to Ipsen, Africans, namely Ghana, also participated in the slave trade through intermarriage, or , meaning "to set up house". It is derived from the Portuguese word "casar", meaning "to marry". Cassare created political and economic bonds between European and African slave traders. Cassare was a pre-European practice used to integrate the "other" from a differing African tribe. Powerful West African groups used these marriages as an alliance used to strengthen their trade networks with European men by marrying off African women from families with ties to the slave trade. Early on in the Atlantic Slave trade, these marriages were common. The marriages were even performed using African customs, which Europeans did not object to, seeing how important the connections were.

European participation in the slave trade

Although Europeans were the market for slaves, Europeans rarely entered the interior of Africa, due to fear of disease and fierce African resistance. In Africa, convicted criminals could be punished by enslavement, a punishment which became more prevalent as slavery became more lucrative. Since most of these nations did not have a prison system, convicts were often sold or used in the scattered local domestic slave market.

In 1778, Thomas Kitchin estimated that Europeans were bringing an estimated 52,000 slaves to the Caribbean yearly, with the French bringing the most Africans to the French West Indies (13,000 out of the yearly estimate). The Atlantic slave trade peaked in the last two decades of the 18th century, during and following the Kongo Civil War. Wars among tiny states along the Niger River's Igbo-inhabited region and the accompanying banditry also spiked in this period. Another reason for surplus supply of enslaved people was major warfare conducted by expanding states, such as the kingdom of Dahomey, the Oyo Empire, and the Asante Empire.

Slavery in Africa and the New World contrasted

Forms of slavery varied both in Africa and in the New World. In general, slavery in Africa was not heritable-that is, the children of slaves were free-while in the Americas, children of slave mothers were considered born into slavery. This was connected to another distinction: slavery in West Africa was not reserved for racial or religious minorities, as it was in European colonies, although the case was otherwise in places such as Somalia, where Bantus were taken as slaves for the ethnic Somalis.

The treatment of slaves in Africa was more variable than in the Americas. At one extreme, the kings of Dahomey routinely slaughtered slaves in hundreds or thousands in sacrificial rituals, and slaves as human sacrifices were also known in Cameroon. On the other hand, slaves in other places were often treated as part of the family, "adopted children", with significant rights including the right to marry without their masters' permission. Scottish explorer Mungo Park wrote:

In the Americas, slaves were denied the right to marry freely and masters did not generally accept them as equal members of the family. New World slaves were considered the property of their owners, and slaves convicted of revolt or murder were executed.

Slave market regions and participation

There were eight principal areas used by Europeans to buy and ship slaves to the Western Hemisphere. The number of enslaved people sold to the New World varied throughout the slave trade. As for the distribution of slaves from regions of activity, certain areas produced far more enslaved people than others. Between 1650 and 1900, 10.2 million enslaved Africans arrived in the Americas from the following regions in the following proportions:

Although the slave trade was largely global, there was considerable intracontinental slave trade in which 8 million people were enslaved within the African continent. Of those who did move out of Africa, 8 million were forced out of Eastern Africa to be sent to Asia.

African kingdoms of the era

There were over 173 city-states and kingdoms in the African regions affected by the slave trade between 1502 and 1853, when Brazil became the last Atlantic import nation to outlaw the slave trade. Of those 173, no fewer than 68 could be deemed nation states with political and military infrastructures that enabled them to dominate their neighbours. Nearly every present-day nation had a pre-colonial predecessor, sometimes an African empire with which European traders had to barter.

Ethnic groups

The different ethnic groups brought to the Americas closely corresponds to the regions of heaviest activity in the slave trade. Over 45 distinct ethnic groups were taken to the Americas during the trade. Of the 45, the ten most prominent, according to slave documentation of the era are listed below.

The transatlantic slave trade resulted in a vast and as yet still unknown loss of life for African captives both in and outside the Americas. Approximately 1.2-2.4 million Africans died during their transport to the New World. More died soon after their arrival. The number of lives lost in the procurement of slaves remains a mystery but may equal or exceed the number who survived to be enslaved.

Estimates of how many Africans died during the slave trade over the 400-year period of slavery vary. Some estimates put the number "between 100 million and 200 million" to "perhaps as many as 14 million". It is alleged that so many slaves died in the sea that sharks' travel patterns changed to feed off the bodies thrown overboard.

Patrick Manning estimates that about 12 million slaves entered the Atlantic trade between the 16th and 19th century, but about 1.5 million died on board ship. About 10.5 million slaves arrived in the Americas. Besides the slaves who died on the Middle Passage, more Africans likely died during the slave raids in Africa and forced marches to ports. Manning estimates that 4 million died inside Africa after capture, and many more died young. Manning's estimate covers the 12 million who were originally destined for the Atlantic, as well as the 6 million destined for Asian slave markets and the 8 million destined for African markets. Of the slaves shipped to The Americas, the largest share went to Brazil and the Caribbean.

African conflicts

According to Kimani Nehusi, the presence of European slavers affected the way in which the legal code in African societies responded to offenders. Crimes traditionally punishable by some other form of punishment became punishable by enslavement and sale to slave traders. According to David Stannard's American Holocaust, 50% of African deaths occurred in Africa as a result of wars between native kingdoms, which produced the majority of slaves. This includes not only those who died in battles but also those who died as a result of forced marches from inland areas to slave ports on the various coasts. The practice of enslaving enemy combatants and their villages was widespread throughout Western and West Central Africa, although wars were rarely started to procure slaves. The slave trade was largely a by-product of tribal and state warfare as a way of removing potential dissidents after victory or financing future wars. However, some African groups proved particularly adept and brutal at the practice of enslaving, such as Oyo, Benin, Igala, Kaabu, Asanteman, Dahomey, the Aro Confederacy and the Imbangala war bands.

In letters written by the Manikongo, Nzinga Mbemba Afonso, to the King João III of Portugal, he writes that Portuguese merchandise flowing in is what is fueling the trade in Africans. He requests the King of Portugal to stop sending merchandise but should only send missionaries. In one of his letters he writes:

The kings of Dahomey sold war captives into transatlantic slavery; they would otherwise have been killed in a ceremony known as the Annual Customs. As one of West Africa's principal slave states, Dahomey became extremely unpopular with neighbouring peoples. Like the Bambara Empire to the east, the Khasso kingdoms depended heavily on the slave trade for their economy. A family's status was indicated by the number of slaves it owned, leading to wars for the sole purpose of taking more captives. This trade led the Khasso into increasing contact with the European settlements of Africa's west coast, particularly the French. Benin grew increasingly rich during the 16th and 17th centuries on the slave trade with Europe; slaves from enemy states of the interior were sold and carried to the Americas in Dutch and Portuguese ships. The Bight of Benin's shore soon came to be known as the "Slave Coast".

King Gezo of Dahomey said in the 1840s:

In 1807, the UK Parliament passed the Bill that abolished the trading of slaves. The King of Bonny (now in Nigeria) was horrified at the conclusion of the practice:

Port factories

After being marched to the coast for sale, enslaved people were held in large forts called factories. The amount of time in factories varied, but Milton Meltzer states in Slavery: A World History that around 4.5% of deaths attributed to the transatlantic slave trade occurred during this phase. In other words, over 820,000 people are believed to have died in African ports such as Benguela, Elmina, and Bonny, reducing the number of those shipped to 17.5 million.

Atlantic shipment

After being captured and held in the factories, slaves entered the infamous Middle Passage. Meltzer's research puts this phase of the slave trade's overall mortality at 12.5%. Their deaths were the result of brutal treatment and poor care from the time of their capture and throughout their voyage. Around 2.2 million Africans died during these voyages, where they were packed into tight, unsanitary spaces on ships for months at a time. Measures were taken to stem the onboard mortality rate, such as enforced "dancing" (as exercise) above deck and the practice of force-feeding enslaved persons who tried to starve themselves. The conditions on board also resulted in the spread of fatal diseases. Other fatalities were suicides, slaves who escaped by jumping overboard. The slave traders would try to fit anywhere from 350 to 600 slaves on one ship. Before the African slave trade was completely banned by participating nations in 1853, 15.3 million enslaved people had arrived in the Americas.

Raymond L. Cohn, an economics professor whose research has focused on economic history and international migration, has researched the mortality rates among Africans during the voyages of the Atlantic slave trade. He found that mortality rates decreased over the history of the slave trade, primarily because the length of time necessary for the voyage was declining. "In the eighteenth century many slave voyages took at least 2½ months. In the nineteenth century, 2 months appears to have been the maximum length of the voyage, and many voyages were far shorter. Fewer slaves died in the Middle Passage over time mainly because the passage was shorter."

Despite the vast profits of slavery, the ordinary sailors on slave ships were badly paid and subject to harsh discipline. Mortality of around 20% was expected in a ship's crew during the course of a voyage; this was due to disease, flogging, overwork, or slave uprisings. Disease ( malaria or yellow fever) was the most common cause of death among sailors. A high crew mortality rate on the return voyage was in the captain's interests as it reduced the number of sailors who had to be paid on reaching the home port.

The slave trade was hated by many sailors, and those who joined the crews of slave ships often did so through coercion or because they could find no other employment.

Seasoning camps

Meltzer also states that 33% of Africans would have died in the first year at the seasoning camps found throughout the Caribbean. Jamaica held one of the most notorious of these camps. Dysentery was the leading cause of death. Around 5 million Africans died in these camps, reducing the number of survivors to about 10 million.

Notable diseases not originally known as present in Americas before 1492 include those such as smallpox, malaria, bubonic plague, typhus, influenza, measles, diphtheria, yellow fever, and whooping cough. During the Atlantic slave trade following the discovery of the New World, diseases such as these possessed the capability of obliterating populations such as the Natives by the masses as short amount of time as a few weeks or months.

Smallpox was one of the epidemics that surrounded the Atlantic slave trade from the 15th to the 18th centuries. Diseases such as smallpox were known for causing a significant decrease in the indigenous population of the New World. An explanation to aid understanding the logistics behind the extensive population decrease includes the topic of immunity. The native population was not immune to this disease in that they did not have the pathogen required to resist the disease. Those such as the European colonizers and the African slaves brought to the New World, however, did possess this pathogen due to having been previously exposed to smallpox. It was known to be a common illness many underwent as children, which in turn built up their immunity to withstand this disease. As a result of the Native Americans no longer being able to work the lands (as the labor required them to mine gold and silver), European colonizers such as the Portuguese took advantage of their access to regions of the African continent such as Angola from which to extract another source of labor, in which Africans had proven to be prime candidates since they survived this case of the disease - also known as variola intermedius - while the Natives had continued to fall to the various illnesses.

For many diseases, the African and Eurasian population were able to have already acquired immunity- being able to resist an infection- due to prior exposure as children in which they were less likely to receive the same illness again. Upon arrival, these diseases were transmitted to the Native populations who did not have immunity due to no prior exposure having been from climates in which these germs, and pathogens surrounding these diseases were not common. Having been exposed to the illness as an adult, some effects would prove to be more enhanced than if they were to be at an adolescent age.

Levels and extent of immunity varies from disease to disease. For smallpox and measles for example, those who survive are equipped with the cellular immunity to combat the disease for the rest of their life in that they cannot contract the disease again. There are also diseases in which immunity does not guarantee that an individual is not susceptible to becoming reinfected.

Inoculation

As epidemiology advances, causes and effective treatments are being discovered to combat historically destructive diseases such as syphilis-which in today can be treated with simple antibiotics such as penicillin and other medications that can inhibit and rid the body of harmful bacteria.

European competition

The trade of enslaved Africans in the Atlantic has its origins in the explorations of Portuguese mariners down the coast of West Africa in the 15th century. Before that, contact with African slave markets was made to ransom Portuguese who had been captured by the intense North African Barbary pirate attacks on Portuguese ships and coastal villages, frequently leaving them depopulated. The first Europeans to use enslaved Africans in the New World were the Spaniards, who sought auxiliaries for their conquest expeditions and labourers on islands such as Cuba and Hispaniola. The alarming decline in the native population had spurred the first royal laws protecting them (Laws of Burgos, 1512-13). The first enslaved Africans arrived in Hispaniola in 1501. After Portugal had succeeded in establishing sugar plantations ( engenhos) in northern Brazil c. 1545, Portuguese merchants on the West African coast began to supply enslaved Africans to the sugar planters. While at first these planters had relied almost exclusively on the native Tupani for slave labour, after 1570 they began importing Africans, as a series of epidemics had decimated the already destabilized Tupani communities. By 1630, Africans had replaced the Tupani as the largest contingent of labour on Brazilian sugar plantations. This ended the European medieval household tradition of slavery, resulted in Brazil's receiving the most enslaved Africans, and revealed sugar cultivation and processing as the reason that roughly 84% of these Africans were shipped to the New World.

As Britain rose in naval power and settled continental North America and some islands of the West Indies, they became the leading slave traders. At one stage the trade was the monopoly of the Royal Africa Company, operating out of London. But, following the loss of the company's monopoly in 1689, Bristol and Liverpool merchants became increasingly involved in the trade. By the late 17th century, one out of every four ships that left Liverpool harbour was a slave trading ship. Much of the wealth on which the city of Manchester, and surrounding towns, was built in the late 18th century, and for much of the 19th century, was based on the processing of slave-picked cotton and manufacture of cloth. Other British cities also profited from the slave trade. Birmingham, the largest gun-producing town in Britain at the time, supplied guns to be traded for slaves. 75% of all sugar produced in the plantations was sent to London, and much of it was consumed in the highly lucrative coffee houses there.

New World destinations

The first slaves to arrive as part of a labour force in the New World reached the island of Hispaniola (now Haiti and the Dominican Republic) in 1502. Cuba received its first four slaves in 1513. Jamaica received its first shipment of 4000 slaves in 1518. Slave exports to Honduras and Guatemala started in 1526.

The first enslaved Africans to reach what would become the United States arrived in July 1526 as part of a Spanish attempt to colonize San Miguel de Gualdape. By November the 300 Spanish colonists were reduced to 100, and their slaves from 100 to 70. The enslaved people revolted in 1526 and joined a nearby Native American tribe, while the Spanish abandoned the colony altogether (1527). The area of the future Colombia received its first enslaved people in 1533. El Salvador, Costa Rica and Florida began their stints in the slave trade in 1541, 1563 and 1581, respectively.

The 17th century saw an increase in shipments. Africans were brought to Point Comfort - several miles downriver from the English colony of Jamestown, Virginia - in 1619. The first kidnapped Africans in English North America were classed as indentured servants and freed after seven years. Virginia law codified chattel slavery in 1656, and in 1662 the colony adopted the principle of partus sequitur ventrem, which classified children of slave mothers as slaves, regardless of paternity. Irish immigrants took slaves to Montserrat in 1651, and in 1655 slaves were shipped to Belize.

Recently bought slaves in Brazil on their way to the farms of the landowners who bought them c. 1830.

Economics of slavery

In France in the 18th century, returns for investors in plantations averaged around 6%; as compared to 5% for most domestic alternatives, this represented a 20% profit advantage. Risks-maritime and commercial-were important for individual voyages. Investors mitigated it by buying small shares of many ships at the same time. In that way, they were able to diversify a large part of the risk away. Between voyages, ship shares could be freely sold and bought.

By far the most financially profitable West Indian colonies in 1800 belonged to the United Kingdom. After entering the sugar colony business late, British naval supremacy and control over key islands such as Jamaica, Trinidad, the Leeward Islands and Barbados and the territory of British Guiana gave it an important edge over all competitors; while many British did not make gains, a handful of individuals made small fortunes. This advantage was reinforced when France lost its most important colony, St. Domingue (western Hispaniola, now Haiti), to a slave revolt in 1791 and supported revolts against its rival Britain, in the name of liberty after the 1793 French revolution. Before 1791, British sugar had to be protected to compete against cheaper French sugar.

Effect on the economy of West Africa

No scholars dispute the harm done to the enslaved people but the effect of the trade on African societies is much debated, due to the apparent influx of goods to Africans. Proponents of the slave trade, such as Archibald Dalzel, argued that African societies were robust and not much affected by the trade. In the 19th century, European abolitionists, most prominently Dr. David Livingstone, took the opposite view, arguing that the fragile local economy and societies were being severely harmed by the trade.

Because the negative effects of slavery on the economies of Africa have been well documented, namely the significant decline in population, some African rulers likely saw an economic benefit from trading their subjects with European slave traders. With the exception of Portuguese-controlled Angola, coastal African leaders "generally controlled access to their coasts, and were able to prevent direct enslavement of their subjects and citizens". Thus, as African scholar John Thornton argues, African leaders who allowed the continuation of the slave trade likely derived an economic benefit from selling their subjects to Europeans. The Kingdom of Benin, for instance, participated in the African slave trade, at will, from 1715 to 1735, surprising Dutch traders, who had not expected to buy slaves in Benin. The benefit derived from trading slaves for European goods was enough to make the Kingdom of Benin rejoin the trans-Atlantic slave trade after centuries of non-participation. Such benefits included military technology (specifically guns and gunpowder), gold, or simply maintaining amicable trade relationships with European nations. The slave trade was, therefore, a means for some African elites to gain economic advantages. Historian Walter Rodney estimates that by c.1770, the King of Dahomey was earning an estimated £250,000 per year by selling captive African soldiers and enslaved people to the European slave-traders. Many West African countries also already had a tradition of holding slaves, which was expanded into trade with Europeans.

The Atlantic trade brought new crops to Africa and also more efficient currencies which were adopted by the West African merchants. This can be interpreted as an institutional reform which reduced the cost of doing business. But the developmental benefits were limited as long as the business including slaving.

Both Thornton and Fage contend that while African political elite may have ultimately benefited from the slave trade, their decision to participate may have been influenced more by what they could lose by not participating. In Fage's article "Slavery and the Slave Trade in the Context of West African History", he notes that for West Africans "...there were really few effective means of mobilizing labour for the economic and political needs of the state" without the slave trade.

Effects on the British economy

Other researchers and historians have strongly contested what has come to be referred to as the "Williams thesis" in academia. David Richardson has concluded that the profits from the slave trade amounted to less than 1% of domestic investment in Britain. Economic historian Stanley Engerman finds that even without subtracting the associated costs of the slave trade (e.g., shipping costs, slave mortality, mortality of British people in Africa, defense costs) or reinvestment of profits back into the slave trade, the total profits from the slave trade and of West Indian plantations amounted to less than 5% of the British economy during any year of the Industrial Revolution. Engerman's 5% figure gives as much as possible in terms of benefit of the doubt to the Williams argument, not solely because it does not take into account the associated costs of the slave trade to Britain, but also because it carries the full-employment assumption from economics and holds the gross value of slave trade profits as a direct contribution to Britain's national income. Historian Richard Pares, in an article written before Williams' book, dismisses the influence of wealth generated from the West Indian plantations upon the financing of the Industrial Revolution, stating that whatever substantial flow of investment from West Indian profits into industry there occurred after emancipation, not before. However, each of these works focus primarily on the slave trade or the Industrial Revolution, and not the main body of the Williams thesis, which was on sugar and slavery itself. Therefore, they do not refute the main body of the Williams thesis.

Seymour Drescher and Robert Anstey argue the slave trade remained profitable until the end, and that moralistic reform, not economic incentive, was primarily responsible for abolition. They say slavery remained profitable in the 1830s because of innovations in agriculture. However, Drescher's Econocide wraps up its study in 1823, and does not address the majority of the Williams thesis, which covers the decline of the sugar plantations after 1823, the emancipation of the slaves in the 1830s, and the subsequent abolition of sugar duties in the 1840s. These arguments do not refute the main body of the Williams thesis, which presents economic data to show that the slave trade was minor compared to the wealth generated by sugar and slavery itself in the British Caribbean.

Karl Marx in his influential economic history of capitalism Das Kapital wrote that "...the turning of Africa into a warren for the commercial hunting of black-skins, signaled the rosy dawn of the era of capitalist production". He argued that the slave trade was part of what he termed the "primitive accumulation" of capital, the 'non-capitalist' accumulation of wealth that preceded and created the financial conditions for Britain's industrialisation.

Demographics

The demographic effects of the slave trade is a controversial and highly debated issue. Although scholars such as Paul Adams and Erick D. Langer have estimated that sub-Saharan Africa represented about 18 percent of the world's population in 1600 and only 6 percent in 1900, the reasons for this demographic shift have been the subject of much debate. In addition to the depopulation Africa experienced because of the slave trade, African nations were left with severely imbalanced gender ratios, with females comprising up to 65 percent of the population in hard-hit areas such as Angola. Moreover, many scholars (such as Barbara N. Ramusack) have suggested a link between the prevalence of prostitution in Africa today with the temporary marriages that were enforced during the course of the slave trade.

Walter Rodney argued that the export of so many people had been a demographic disaster which left Africa permanently disadvantaged when compared to other parts of the world, and it largely explains the continent's continued poverty. He presented numbers showing that Africa's population stagnated during this period, while those of Europe and Asia grew dramatically. According to Rodney, all other areas of the economy were disrupted by the slave trade as the top merchants abandoned traditional industries in order to pursue slaving, and the lower levels of the population were disrupted by the slaving itself.

Other scholars accused Walter Rodney of mischaracterizing the trade between Africans and Europeans. They argue that Africans, or more accurately African elites, deliberately let European traders join in an already large trade in enslaved people and that they were not patronized.

As Joseph E. Inikori argues, the history of the region shows that the effects were still quite deleterious. He argues that the African economic model of the period was very different from the European model, and could not sustain such population losses. Population reductions in certain areas also led to widespread problems. Inikori also notes that after the suppression of the slave trade Africa's population almost immediately began to rapidly increase, even prior to the introduction of modern medicines.

Legacy of racism

Walter Rodney states

Similarly, John Darwin writes "The rapid conversion from white indentured labour to black slavery... made the English Caribbean a frontier of civility where English (later British) ideas about race and slave labour were ruthlessly adapted to local self-interest...Indeed, the root justification for the system of slavery and the savage apparatus of coercion on which its preservation depended was the ineradicable barbarism of the slave population, a product, it was argued, of its African origins".

End of the Atlantic slave trade

In Britain, America, Portugal and in parts of Europe, opposition developed against the slave trade. Davis says that abolitionists assumed "that an end to slave imports would lead automatically to the amelioration and gradual abolition of slavery". In Britain and America, opposition to the trade was led by the Religious Society of Friends (Quakers) and establishment Evangelicals such as William Wilberforce. Many people joined the movement and they began to protest against the trade, but they were opposed by the owners of the colonial holdings. Following Lord Mansfield's decision in 1772, many abolitionists and slave-holders believed that slaves became free upon entering the British isles. However, in reality slavery continued in Britain right up to abolition in the 1830s. The Mansfield ruling on Somerset v Stewart only decreed that a slave could not be transported out of England against his will.

Under the leadership of Thomas Jefferson, the new state of Virginia in 1778 became the first state and one of the first jurisdictions anywhere to stop the importation of slaves for sale; it made it a crime for traders to bring in slaves from out of state or from overseas for sale; migrants from other states were allowed to bring their own slaves. The new law freed all slaves brought in illegally after its passage and imposed heavy fines on violators. All the other states followed suit, although South Carolina reopened the slave trade in 1803.

Denmark, which had been active in the slave trade, was the first country to ban the trade through legislation in 1792, which took effect in 1803. Britain banned the slave trade in 1807, imposing stiff fines for any slave found aboard a British ship ( see Slave Trade Act 1807). The Royal Navy moved to stop other nations from continuing the slave trade and declared that slaving was equal to piracy and was punishable by death. The United States Congress passed the Slave Trade Act of 1794, which prohibited the building or outfitting of ships in the U.S. for use in the slave trade. The U.S. Constitution barred a federal prohibition on importing slaves for 20 years; at that time the Act Prohibiting Importation of Slaves prohibited imports on the first day the Constitution permitted: January 1, 1808.

British abolitionism

On 22 February 1807, the House of Commons passed a motion 283 votes to 16 to abolish the Atlantic slave trade. Hence, the slave trade was abolished, but not the still-economically viable institution of slavery itself, which provided Britain's most lucrative import at the time, sugar. Abolitionists did not move against sugar and slavery itself until after the sugar industry went into terminal decline after 1823.

At the same time, although without mutual consultation, the United States abolished the slave trade the same year, but not its internal slave trade which became the dominant character in American slavery until the 1860s. In 1805 the British Order-in-Council had restricted the importation of slaves into colonies that had been captured from France and the Netherlands. Britain continued to press other nations to end its trade; in 1810 an Anglo-Portuguese treaty was signed whereby Portugal agreed to restrict its trade into its colonies; an 1813 Anglo-Swedish treaty whereby Sweden outlawed its slave trade; the Treaty of Paris 1814 where France agreed with Britain that the trade is "repugnant to the principles of natural justice" and agreed to abolish the slave trade in five years; the 1814 Anglo-Netherlands treaty where the Dutch outlawed its slave trade.

Castlereagh and Palmerston's diplomacy

Abolitionist opinion in Britain was strong enough in 1807 to abolish the slave trade in all British possessions, although slavery itself persisted in the colonies until 1833. Abolitionists after 1807 focused on international agreements to abolish the slave trade. Foreign Minister Castlereagh switched his position and became a strong supporter of the movement. Britain arrange treaties with Portugal Sweden and Denmark, 1810-1814, whereby they agreed to end or restrict their trading. These were preliminary to the Congress of Vienna negotiations that Castlereagh dominated and which resulted in a general declaration condemning the slave trade. The problem was that the treaties and declarations were hard to enforce, given the very high profits available to private interests. As Foreign Minister, Castlereagh cooperated with senior officials to use the Royal Navy to detect and capture slave ships. He used diplomacy to make search and seize agreements with all the government whose ships were trading. There was serious friction with the United States, where the southern slave interest was politically powerful. Washington recoiled at British policing of the high seas. Spain France and Portugal also relied on the international slave trade to supply their colonial plantations. As more and more diplomatic arrangements were made by Castlereagh, the owners of slave ships started flying false flags of nations that had not agreed, especially the United States. It was illegal under American law for American ships to engage in the slave trade, but the idea of Britain enforcing American laws was unacceptable to Washington. Lord Palmerston and other British foreign ministers continued the Castlereagh policies. Eventually, in 1842 in 1845, an arrangement was reached between London and Washington. With the arrival of a staunchly anti-slavery government in Washington in 1861, the Atlantic slave trade was doomed. In the long run, Castlereagh's strategy on how to stifle the slave trade proved successful.

The Royal Navy's West Africa Squadron, established in 1808, grew by 1850 to a force of some 25 vessels, which were tasked with combating slavery along the African coast. Between 1807 and 1860, the Royal Navy's Squadron seized approximately 1,600 ships involved in the slave trade and freed 150,000 Africans who were aboard these vessels. Several hundred slaves a year were transported by the navy to the British colony of Sierra Leone, where they were made to serve as "apprentices" in the colonial economy until the Slavery Abolition Act 1833.

Last slave ship to the United States

The last recorded slave ship to land on U.S. soil was the Clotilde, which in 1859 illegally smuggled a number of Africans into the town of Mobile, Alabama. The Africans on board were sold as slaves; however, slavery in the U.S. was abolished five years later following the end of the American Civil War in 1865. The last survivor of the voyage was Cudjoe Lewis, who died in 1935. The last country to ban the Atlantic slave trade was Brazil in 1831. However, a vibrant illegal trade continued to ship large numbers of enslaved people to Brazil and also to Cuba until the 1860s, when British enforcement and further diplomacy finally ended the Atlantic slave trade. In 1870, Portugal ended the last trade route with the Americas, where the last country to import slaves was Brazil. In Brazil, however, slavery itself was not ended until 1888, making it the last country in the Americas to end involuntary servitude.

Economic motivation to end the slave trade

The historian Walter Rodney contends that it was a decline in the profitability of the triangular trades that made it possible for certain basic human sentiments to be asserted at the decision-making level in a number of European countries-Britain being the most crucial because it was the greatest carrier of African captives across the Atlantic. Rodney states that changes in productivity, technology, and patterns of exchange in Europe and the Americas informed the decision by the British to end their participation in the trade in 1807. In 1809 President James Madison outlawed the slave trade with the United States.

Nevertheless, Michael Hardt and Antonio Negri argue that it was neither a strictly economic nor moral matter. First, because slavery was (in practice) still beneficial to capitalism, providing not only an influx of capital but also disciplining hardship into workers (a form of "apprenticeship" to the capitalist industrial plant). The more "recent" argument of a "moral shift" (the basis of the previous lines of this article) is described by Hardt and Negri as an "ideological" apparatus in order to eliminate the sentiment of guilt in western society. Although moral arguments did play a secondary role, they usually had major resonance when used as a strategy to undercut competitors' profits. This argument holds that Eurocentric history has been blind to the most important element in this fight for emancipation, precisely, the constant revolt and the antagonism of slaves' revolts. The most important of those being the Haitian Revolution. The shock of this revolution in 1804, certainly introduces an essential political argument into the end of the slave trade, which happened only three years later.

However, both James Stephen (British politician) and Henry Brougham, 1st Baron Brougham and Vaux wrote that the slave trade could be abolished for the benefit of the British colonies, and the latter's pamphlet was often used in parliamentary debates in favour of abolition. William Pitt the Younger argued on the basis of these writings that the British colonies would be better off, in economics as well as security, if the trade was abolished. As a result, according to historian Christer Petley, abolitionists argued, and even some absentee plantation owners accepted, that the trade could be abolished "without substantial damage to the plantation economy". William Grenville, 1st Baron Grenville argued that "the slave population of the colonies could be maintained without it." Petley points out that government took the decision to abolish the trade "with the express intention of improving, not destroying, the still-lucrative plantation economy of the British West Indies."

African diaspora

The African diaspora which was created via slavery has been a complex interwoven part of American history and culture. In the United States, the success of Alex Haley's book Roots: The Saga of an American Family, published in 1976, and , the subsequent television miniseries based upon it, broadcast on the ABC network in January 1977, led to an increased interest and appreciation of African heritage amongst the African-American community. The influence of these led many African Americans to begin researching their family histories and making visits to West Africa. In turn, a tourist industry grew up to supply them. One notable example of this is through the Roots Homecoming Festival held annually in the Gambia, in which rituals are held through which African Americans can symbolically "come home" to Africa. Issues of dispute have however developed between African Americans and African authorities over how to display historic sites that were involved in the Atlantic slave trade, with prominent voices in the former criticising the latter for not displaying such sites sensitively, but instead treating them as a commercial enterprise.

"Back to Africa"

Rastafari movement

In 1998, UNESCO designated 23 August as International Day for the Remembrance of the Slave Trade and its Abolition. Since then there have been a number of events recognizing the effects of slavery.

At the 2001 World Conference Against Racism in Durban, South Africa, African nations demanded a clear apology for slavery from the former slave-trading countries. Some nations were ready to express an apology, but the opposition, mainly from the United Kingdom, Portugal, Spain, the Netherlands, and the United States blocked attempts to do so. A fear of monetary compensation might have been one of the reasons for the opposition. As of 2009, efforts are underway to create a UN Slavery Memorial as a permanent remembrance of the victims of the Atlantic slave trade.

In 1999, President Mathieu Kerekou of Benin (formerly the Kingdom of Dahomey) issued a national apology for the role Africans played in the Atlantic slave trade. Luc Gnacadja, minister of environment and housing for Benin, later said: "The slave trade is a shame, and we do repent for it." Researchers estimate that 3 million slaves were exported out of the Slave Coast bordering the Bight of Benin.

Netherlands

United Kingdom

On 27 November 2006, British Prime Minister Tony Blair made a partial apology for Britain's role in the African slavery trade. However African rights activists denounced it as "empty rhetoric" that failed to address the issue properly. They feel his apology stopped shy to prevent any legal retort. Blair again apologized on March 14, 2007.

On 24 August 2007, Ken Livingstone ( Mayor of London) apologized publicly for London's role in the slave trade. "You can look across there to see the institutions that still have the benefit of the wealth they created from slavery," he said, pointing towards the financial district, before breaking down in tears. He said that London was still tainted by the horrors of slavery. Jesse Jackson praised Mayor Livingstone and added that reparations should be made.

United States

On 24 February 2007, the Virginia General Assembly passed House Joint Resolution Number 728 acknowledging "with profound regret the involuntary servitude of Africans and the exploitation of Native Americans, and call for reconciliation among all Virginians". With the passing of that resolution, Virginia became the first of the 50 United States to acknowledge through the state's governing body their state's involvement in slavery. The passing of this resolution came on the heels of the 400th-anniversary celebration of the city of Jamestown, Virginia, which was the first permanent English colony to survive in what would become the United States. Jamestown is also recognized as one of the first slave ports of the American colonies. On 31 May 2007, the Governor of Alabama, Bob Riley, signed a resolution expressing "profound regret" for Alabama's role in slavery and apologizing for slavery's wrongs and lingering effects. Alabama is the fourth state to pass a slavery apology, following votes by the legislatures in Maryland, Virginia, and North Carolina.

On 30 July 2008, the United States House of Representatives passed a resolution apologizing for American slavery and subsequent discriminatory laws. The language included a reference to the "fundamental injustice, cruelty, brutality and inhumanity of slavery and Jim Crow" segregation. On 18 June 2009, the United States Senate issued an apologetic statement decrying the "fundamental injustice, cruelty, brutality, and inhumanity of slavery". The news was welcomed by President Barack Obama.

The Atlantic slave trade or transatlantic slave trade involved the transportation by slave traders of enslaved African people, mainly to the Americas. The slave trade regularly used the triangular trade route and its Middle Passage, and existed from the 16th to the 19th centuries.

# data[].attributes.body
The triangular "Middle Passage" was the primary trade route used for the Atlantic slave trade.

# data[].attributes.attachment_link.readable_text
The Middle Passage was the stage of the triangular trade in which millions of dark-skinned West Africans were forcibly transported to the New World as part of the Atlantic slave trade. Ships departed Europe for West African markets with manufactured goods (first side of the triangle), which were traded for humans, as Africans were willing to capture and sell members of other tribes.

Special slave ships transported the human cargo, in wretched conditions, males and females separated, across the Atlantic (second side of the triangle). Mortality was high; those with strong bodies survived. Young females were raped by the crew. The proceeds from sale of the enslaved Africans were then used to buy hides, tobacco, sugar, rum, and raw materials[which? ], which would be transported back to northern Europe (third side of the triangle) to complete the triangle.

The First Passage was the forced march of captives (future slaves) from their inland homes to African ports, such as Elmina, where they were imprisoned until they can be loaded onto a buying ship. The Final Passage was the journey from the port of disembarkation, such as Charleston, South Carolina, to the plantation or other destination where they would be put to work. The Middle Passage across the Atlantic joined these two. Voyages on the Middle Passage were large financial undertakings, generally organized by companies or groups of investors[example needed ] rather than individuals.

The "Middle Passage" was considered a time of in-betweenness for those being traded from Africa to America. The close quarters and intentional division of pre-established African communitiesom selling the cargo of enslaved by the ship crew motivated captive Africans to forge bonds of kinship which then created forced transatlantic communities.

Traders from the Americas and Caribbean received the enslaved Africans. European powers such as Portugal, Britain, Spain, France, the Netherlands, Denmark-Norway, Sweden, Courland and Brandenburg, as well as traders from Brazil and North America, took part in the trade. The enslaved Africans came mostly from the regions of Senegambia, Upper Guinea, Windward Coast, Gold Coast, Bight of Benin, Bight of Biafra, and Dutch Loango-Angola. Between 1525 and 1859, the slave trade from the Bight of Biafra alone accounted for over two-thirds of slaves exported to the New World.

An estimated 15% of the Africans died at sea, with mortality rates considerably higher in Africa itself during the process of capturing and transporting indigenous people to the ships. The total number of African deaths directly attributable to the Middle Passage voyage is estimated at up to two million; a broader look at African deaths directly attributable to the institution of slavery from 1500 to 1900 suggests up to four million African deaths.

The first known transatlantic slave ship sailed from São Tomé to New Spain in 1525, outsourced by Genoese bankers who paid the Spanish court for the Asiento de Negros. Portuguese slavers had a near monopoly on the export of slaves from Africa until about 1640, while in the second half of the 17th century competing Dutch, British and French traders concentrated the trade in slaves on the Caribbean islands of Curaçao, Martinique and Barbados from where they would be exported to the mainland. During the 18th century, when the slave trade transported about 6 million Africans, British slavers carried almost 2.5 million.

The duration of the transatlantic voyage varied widely, from one to six months depending on weather conditions. The journey became more efficient over the centuries; while an average transatlantic journey of the early 16th century lasted several months, by the 19th century the crossing often required fewer than six weeks.

It is believed that African kings, warlords and private kidnappers sold captives to Europeans who held several coastal forts. The captives were usually force-marched to these ports along the western coast of Africa, where they were held for sale to the European or American slave traders in the barracoons. Typical slave ships contained several hundred slaves with about 30 crew members.

The male captives were normally chained together in pairs to save space; right leg to the next man's left leg - while the women and children may have had somewhat more room. The chains or hand and leg cuffs were known as bilboes, which were among the many tools of the slave trade, and which were always in short supply. Bilboes were mainly used on men, and they consisted of two iron shackles locked on a post and were usually fastened around the ankles of two men. At best, captives were fed beans, corn, yams, rice, and palm oil. Slaves were fed one meal a day with water, if at all. When food was scarce, slaveholders would get priority over the slaves. Sometimes captives were allowed to move around during the day, but many ships kept the shackles on throughout the arduous journey. Aboard certain French ships, slaves were brought on deck to periodically receive fresh air. While female slaves were typically permitted to be on deck more frequently, male slaves would be watched closely to prevent revolt when above deck.

Slaves below the decks lived for months in conditions of squalor and indescribable horror. Disease spread and ill health was one of the biggest killers. Mortality rates were high, and death made these conditions below the decks even worse. Even though the corpses were thrown overboard, many crew members avoided going into the hold. The slaves who had already been ill ridden were not always found immediately. Many of the living slaves could have been shackled to someone that was dead for hours and sometimes days.

Most contemporary historians estimate that between 9.4 and 12.6 million Africans embarked for the New World. Disease and starvation due to the length of the passage were the main contributors to the death toll with amoebic dysentery and scurvy causing the majority of deaths. Additionally, outbreaks of smallpox, syphilis, measles, and other diseases spread rapidly in the close-quarter compartments.

The rate of death increased with the length of the voyage, since the incidence of dysentery and of scurvy increased with longer stints at sea as the quality and amount of food and water diminished. In addition to physical sickness, many slaves became too depressed to eat or function efficiently due to loss of freedom, family, security, and their own humanity.

Sailing technologies

The need for profits in the 18th century's Atlantic market economy drove changes in ship designs and in managing human cargo, which included enslaved Africans and the mostly white crew. Improvements in air flow on board the ships helped to decrease the infamous mortality rate that these ships had become known for throughout the 16th and 17th centuries. The new designs that allowed ships to navigate faster and into rivers' mouths ensured access to many more enslaving posts along the West African coast. The monetary value of enslaved Africans on any given American auction-block during the mid-18th century ranged between $800 and $1,200, which in modern times would be equivalent to $32,000-48,000 per person ($100 then is now worth $4,000 due to inflation). Therefore, ship captains and investors sought technologies that would protect their human cargo.

Throughout the height of the Atlantic slave trade (1570-1808), slave ships were normally smaller than traditional cargo ships, with most slave ships weighing between 150 and 250 tons. This equated to about 350 to 450 enslaved Africans on each slave ship, or 1.5 to 2.4 per ton. The English ships of the time normally fell on the larger side of this spectrum and the French on the smaller side. Ships purposely designed to be smaller and more maneuverable were meant to navigate the African coastal rivers into farther inland ports; these ships therefore increased the effects of the slave trade on Africa. Additionally, the ships' sizes increased slightly throughout the 1700s; however the number of enslaved Africans per ship remained the same. This reduction in the ratio of enslaved Africans to ship tonnage was designed to increase the amount of space per person and thus improve the survival chances of everyone on board. These ships also had temporary storage decks which were separated by an open latticework or grate bulkhead, Ship masters would presumably use these chambers to divide enslaved Africans and help prevent mutiny. Some ships developed by the turn of the 19th century even had ventilation ports built into the sides and between gun ports (with hatches to keep inclement weather out). These open deck designs increased airflow and thus helped improve survival rates, diminishing potential investment losses.

Another major factor in "cargo protection" was the increase in knowledge of diseases and medicines (along with the inclusion of a variety of medicines on the ships). First the Dutch East India Company in the 18th century, followed by some other countries and companies in the late 18th early 19th centuries, realized that the inclusion of surgeons and other medical practitioners aboard their ships was an endeavor that proved too costly for the benefits. So instead of including medical personnel they just stocked the ships with a large variety of medicines; while this was better than no medicines, and given the fact that many crew members at least had some idea of how disease was spread, without the inclusion of medical personnel the mortality rate was still very high in the 18th century.

Slave treatment and resistance

Slaves' treatment was horrific because the captured African men and women were considered less than human; they were "cargo", or "goods", and treated as such; they were transported for marketing. Women with children were not as desirable for they took up too much space and toddlers were not wanted because of everyday maintenance. For example, the Zong, a British slaver, took too many slaves on a voyage to the New World in 1781. Overcrowding combined with malnutrition and disease killed several crew members and around 60 slaves. Bad weather made the Zong's voyage slow and lack of drinking water became a concern. The crew decided to drown some slaves at sea, to conserve water and allow the owners to collect insurance for lost cargo. About 130 slaves were killed and a number chose to kill themselves in defiance, by jumping into the water willingly. The Zong incident became fuel for the abolitionist movement and a major court case, as the insurance company refused to compensate for the loss.

While slaves were generally kept fed and supplied with drink as healthy slaves were more valuable, if resources ran low on the long, unpredictable voyages, the crew received preferential treatment. Slave punishment and torture was very common, as on the voyage the crew had to turn independent people into obedient slaves. Pregnant women on the ships who delivered their babies aboard risked the chance of their children being killed in order for the mothers to be sold. The worst punishments were for rebelling; in one instance a captain punished a failed rebellion by killing one involved slave immediately, and forcing two other slaves to eat his heart and liver.

As a way to counteract disease and suicide attempts, the crew would force the slaves onto the deck of the ship for exercise, usually resulting in beatings because the slaves would be unwilling to dance for them or interact. These beatings would often be severe and could result in the slave dying or becoming more susceptible to diseases.

Slaves resisted in many ways. The two most common types of resistance were refusal to eat and suicide. Suicide was a frequent occurrence, often by refusal of food or medicine or jumping overboard, as well as by a variety of other opportunistic means. If a slave jumped overboard, they would often be left to drown or shot from the boat. Over the centuries, some African peoples, such as the Kru, came to be understood as holding substandard value as slaves, because they developed a reputation for being too proud for slavery, and for attempting suicide immediately upon losing their freedom.

Both suicide and self-starving were prevented as much as possible by slaver crews; slaves were often force-fed or tortured until they ate, though some still managed to starve themselves to death; slaves were kept away from means of suicide, and the sides of the deck were often netted. Slaves were still successful, especially at jumping overboard. Often when an uprising failed, the mutineers would jump en masse into the sea. Slaves generally believed that if they jumped overboard, they would be returned to their family and friends in their village or to their ancestors in the afterlife.

Suicide by jumping overboard was such a problem that captains had to address it directly in many cases. They used the sharks that followed the ships as a terror weapon. One captain, who had a rash of suicides on his ship, took a woman and lowered her into the water on a rope, and pulled her out as fast as possible. When she came in view, the sharks had already killed her-and bitten off the lower half of her body.

In order to interact with each other on the voyage, slaves created a communication system unbeknownst to Europeans: They would construct choruses on the passages using their voices, bodies, and ships themselves; the hollow design of the ships allowed slaves to use them as percussive instruments and to amplify their songs. This combination of "instruments" was both a way for slaves to communicate as well as create a new identity since slavers attempted to strip them of that. Although most slaves were from various regions around Africa, their situation allowed them to come together and create a new culture and identity aboard the ships with a common language and method of communication:

[C]all and response soundings allowed men and women speaking different languages to communicate about the conditions of their captivity. In fact, on board the Hubridas, what began as murmurs and morphed into song erupted before long into the shouts and cries of coordinated revolt.

This communication was a direct subversion of European authority and allowed slaves to have a form of power and identity otherwise prohibited. Furthermore, such organization and coming together enabled revolts and uprisings to actually be coordinated and successful at times.

Aboard ships, the captives were not always willing to follow orders. Sometimes they reacted in violence. Slave ships were designed and operated to try to prevent the slaves from revolting. Resistance among the slaves usually ended in failure and participants in the rebellion were punished severely. About one out of ten ships experienced some sort of rebellion.

Ottobah Cugoano, who was taken from Africa as a slave when he was a child, later described an uprising aboard the ship on which he was transported to the West Indies:

When we found ourselves at last taken away, death was more preferable than life, and a plan was concerted amongst us, that we might burn and blow up the ship, and to perish all together in the flames.

The number of rebels varied widely; often the uprisings would end with the death of a few slaves and crew. Surviving rebels were punished or executed as examples to the other slaves on board.

Slaves also resisted through certain manifestations of their religions and mythology. They would appeal to their gods for protection and vengeance upon their captors, and would also try to curse and otherwise harm the crew using idols and fetishes. One crew found fetishes in their water supply, placed by slaves who believed they would kill all who drank from it.

Sailors and crew

While the owners and captains of slave ships could expect vast profits, the ordinary sailors were often badly paid and subject to brutal discipline. Sailors often had to live and sleep without shelter on the open deck for the entirety of the Atlantic voyage as the entire space below deck was occupied by enslaved people.

A crew mortality rate of around 20% was expected during a voyage, with sailors dying as a result of disease (specifically malaria and yellow fever), flogging or slave uprisings. A high crew mortality rate on the return voyage was in the captain's interests as it reduced the number of sailors who had to be paid on reaching the home port. Crew members who survived were frequently cheated out of their wages on their return.

The sailors were often employed through coercion as they generally knew about and hated the slave trade. In port towns, recruiters and tavern owners would induce sailors to become very drunk (and indebted) and then offer to relieve their debt if they signed contracts with slave ships. If they did not, they would be imprisoned. Sailors in prison had a hard time getting jobs outside of the slave ship industry since most other maritime industries would not hire "jail-birds", so they were forced to go to the slave ships anyway.

The Middle Passage was the stage of the triangular trade in which millions of dark-skinned West Africans were forcibly transported to the New World as part of the Atlantic slave trade. Ships departed Europe for West African markets with manufactured goods (first side of the triangle), which were traded for humans, as Africans were willing to capture and sell members of other tribes.

The history of slavery spans many cultures, nationalities, and religions from ancient times to the present day. However the social, economic, and legal positions of slaves have differed vastly in different systems of slavery in different times and places.

Slavery occurs relatively rarely among hunter-gatherer populations because it develops under conditions of social stratification. Slavery operated in the very first civilizations (such as Sumer in Mesopotamia, which dates back as far as 3500 BCE). Slavery features in the Mesopotamian Code of Hammurabi (c. 1860 BCE), which refers to it as an established institution. Slavery became common within much of Europe during the Early Middle Ages and it continued into the following centuries. The Byzantine-Ottoman wars (1265-1479) and the Ottoman wars in Europe (14th to 20th centuries) resulted in the capture of large numbers of Christian slaves. The Dutch, French, Spanish, Portuguese, British, Arabs and a number of West African kingdoms played a prominent role in the Atlantic slave trade, especially after 1600. The Republic of Ragusa became the first European country to ban the slave trade in 1416. In modern times Denmark-Norway abolished the trade in 1802.

Although slavery is no longer legal anywhere in the world (with the exception of penal labour), human trafficking remains an international problem and an estimated 25-40 million people were enslaved as of 2013, the majority in Asia. During the 1983-2005 Second Sudanese Civil War people were taken into slavery. Evidence emerged in the late 1990s of systematic child-slavery and -trafficking on cacao plantations in West Africa. Slavery continues into the 21st century. Although Mauritania criminalized slavery in August 2007, an estimated up to 600,000 men, women and children, or 20% of the population of Mauritania, are currently enslaved, many of them used as bonded labor. Slavery in the 21st century continues, with the top ten countries with the highest prevalence according to the Global Slavery Index being North Korea, Eritrea, Burundi, the Central African Republic, Afghanistan, Mauritania, South Sudan, Pakistan, Cambodia and Iran. Islamist quasi-states such as the Islamic State of Iraq and the Levant and Boko Haram have abducted and enslaved women and children (often to serve as sex slaves).

Evidence of slavery predates written records, and has existed in many cultures. Mass slavery requires economic surpluses and a high population density to be viable. Due to these factors, the practice of slavery would have only proliferated after the invention of agriculture during the Neolithic Revolution, about 11,000 years ago.

C. 1480 BCE, fugitive slave treaty between Idrimi of Alakakh (now Tell Atchana) and Pillia of Kizzuwatna (now Cilicia).

French historian Fernand Braudel noted that slavery was endemic in Africa and part of the structure of everyday life. "Slavery came in different guises in different societies: there were court slaves, slaves incorporated into princely armies, domestic and household slaves, slaves working on the land, in industry, as couriers and intermediaries, even as traders". During the 16th century, Europe began to outpace the Arab world in the export traffic, with its slave traffic from Africa to the Americas. The Dutch imported slaves from Asia into their colony in South Africa. In 1807 Britain, which held extensive, although mainly coastal, colonial territories on the African continent (including southern Africa), made the international slave trade illegal, as did the United States in 1808.

Slavery in Ethiopia persisted until 1942. The Anti-Slavery Society estimated that there were 2,000,000 slaves in the early 1930s, out of an estimated population of between 8 and 16 million. It was finally abolished by order of emperor Haile Selassie on 26 August 1942.

When British rule was first imposed on the Sokoto Caliphate and the surrounding areas in northern Nigeria at the turn of the 20th century, approximately 2 million to 2.5 million people there were slaves. Slavery in northern Nigeria was finally outlawed in 1936.

Elikia M'bokolo, April 1998, Le Monde diplomatique. Quote: "The African continent was bled of its human resources via all possible routes. Across the Sahara, through the Red Sea, from the Indian Ocean ports and across the Atlantic. At least ten centuries of slavery for the benefit of the Muslim countries (from the ninth to the nineteenth)." He continues: "Four million slaves exported via the Red Sea, another four million through the Swahili ports of the Indian Ocean, perhaps as many as nine million along the trans-Saharan caravan route, and eleven to twenty million (depending on the author) across the Atlantic Ocean"

Zanzibar was once East Africa's main slave-trading port, and under Omani Arabs in the 19th century, as many as 50,000 slaves were passing through the city each year.

Prior to the 16th century, the bulk of slaves exported from Africa were shipped from East Africa to the Arabian peninsula. Zanzibar became a leading port in this trade. Arab slave traders differed from European ones in that they would often conduct raiding expeditions themselves, sometimes penetrating deep into the continent. They also differed in that their market greatly preferred the purchase of female slaves over male ones.

The increased presence of European rivals along the East coast led Arab traders to concentrate on the overland slave caravan routes across the Sahara from the Sahel to North Africa. The German explorer Gustav Nachtigal reported seeing slave caravans departing from Kukawa in Bornu bound for Tripoli and Egypt in 1870. The slave trade represented the major source of revenue for the state of Bornu as late as 1898. The eastern regions of the Central African Republic have never recovered demographically from the impact of 19th-century raids from the Sudan and still have a population density of less than 1 person/km². During the 1870s, European initiatives against the slave trade caused an economic crisis in northern Sudan, precipitating the rise of Mahdist forces. Mahdi's victory created an Islamic state, one that quickly reinstituted slavery.

The Middle Passage, the crossing of the Atlantic to the Americas, endured by slaves laid out in rows in the holds of ships, was only one element of the well-known triangular trade engaged in by Portuguese, Dutch, Danish-Norwegians, French, British and others. Ships having landed slaves in Caribbean ports would take on sugar, indigo, raw cotton, and later coffee, and make for Liverpool, Nantes, Lisbon or Amsterdam. Ships leaving European ports for West Africa would carry printed cotton textiles, some originally from India, copper utensils and bangles, pewter plates and pots, iron bars more valued than gold, hats, trinkets, gunpowder and firearms and alcohol. Tropical shipworms were eliminated in the cold Atlantic waters, and at each unloading, a profit was made.

While talking about the slave trade in East Africa in his journals, "To overdraw its evil is a simple impossibility."

To overdraw its evil is a simple impossibility.

David Livingstone while travelling in the African Great Lakes Region in 1866 described a trail of slaves as such:

19th June 1866 - We passed a woman tied by the neck to a tree and dead, the people of the country explained that she had been unable to keep up with the other slaves in a gang, and her master had determined that she should not become anyone's property if she recovered.
26th June. - ...We passed a slave woman shot or stabbed through the body and lying on the path: a group of men stood about a hundred yards off on one side, and another of the women on the other side, looking on; they said an Arab who passed early that morning had done it in anger at losing the price he had given for her, because she was unable to walk any longer.
27th June 1866 - To-day we came upon a man dead from starvation, as he was very thin. One of our men wandered and found many slaves with slave-sticks on, abandoned by their masters from want of food; they were too weak to be able to speak or say where they had come from; some were quite young.

The strangest disease I have seen in this country seems really to be broken-heartedness, and it attacks free men who have been captured and made slaves... Twenty one were unchained, as now safe; however all ran away at once; but eight with many others still in chains, died in three days after the crossing. They described their only pain in the heart, and placed the hand correctly on the spot, though many think the organ stands high up in the breast-bone.

African states played a role in the slave trade, and slavery was a common practice among Sub Saharan Africans before the involvement of the Arabs, Berbers and Europeans. There were three types: those who were slaves through conquest, those who were slaves due to unpaid debts, or those whose parents gave them as slaves to tribal chiefs. Chieftains would barter their slaves to Arab, Berber, Ottoman or European buyers for rum, spices, cloth or other goods. Selling captives or prisoners was commonly practiced among Africans, Turks, Berbers and Arabs during that era. However, as the Atlantic slave trade increased its demand, local systems which primarily serviced indentured servitude expanded. European slave trading, as a result, was the most pivotal change in the social, economic, cultural, spiritual, religious, political dynamics of the concept of slave trading. It ultimately undermined local economies and political stability as villages' vital labour forces were shipped overseas as slave raids and civil wars became commonplace. Crimes which were previously punishable by some other means became punishable by enslavement.

The kings of Dahomey sold their war captives into transatlantic slavery, who otherwise may have been killed in a ceremony known as the Annual Customs. As one of West Africa's principal slave states, Dahomey became extremely unpopular with neighbouring peoples. Like the Bambara Empire to the east, the Khasso kingdoms depended heavily on the slave trade for their economy. A family's status was indicated by the number of slaves it owned, leading to wars for the sole purpose of taking more captives. This trade led the Khasso into increasing contact with the European settlements of Africa's west coast, particularly the French. Benin grew increasingly rich during the 16th and 17th centuries on the slave trade with Europe; slaves from enemy states of the interior were sold, and carried to the Americas in Dutch and Portuguese ships. The Bight of Benin's shore soon came to be known as the "Slave Coast".

The slave trade is the ruling principle of my people. It is the source and the glory of their wealth...the mother lulls the child to sleep with notes of triumph over an enemy reduced to slavery...

In 1807, under internal and external pressures, the United Kingdom made illegal the international trade in slaves. The Royal Navy was deployed to prevent slavers from the United States, France, Spain, Portugal, Holland, West Africa and Arabia. The King of Bonny (now in Nigeria) allegedly became dissatisfied of the British intervention in stopping slave trading.

We think this trade must go on. That is the verdict of our oracle and the priests. They say that your country, however great, can never stop a trade ordained by God himself.

Joseph Miller states that African buyers would prefer males, but in reality, women and children would be more easily captured as men fled. Those captured would be sold for various reasons such as food, debts, or servitude. Once captured, the journey to the coast killed many and weakened others. Disease engulfed many, and insufficient food damaged those who made it to the coasts. Scurvy was so common that it was known as mal de Luanda (Luanda sickness). The assumption for those who died on the journey died from malnutrition. As food was limited, water may have been just as bad. Dysentery was widespread and poor sanitary conditions at ports did not help. Since supplies were poor, slaves were not equipped with the best clothing that further exposed to more diseases.

If the fear of disease caused terror, the psyche of slaves for being captured was just as terrifying. The most popular assumption for being captured was Europeans were cannibals. Stories and rumours spread that whites captured Africans to eat them. Olaudah Equiano accounts his experience about the sorrow slaves encountered at the ports. He talks about his first moment on a slave ship and asked if he was going to be eaten. Yet, the worst for slaves has only begun, and the journey on the water proved to be more terrifying. For every 100 Africans captured, only 64 would reach the coast, and only about 50 would reach the New World.

Others believe that slavers had a vested interest in capturing rather than killing, and in keeping their captives alive; and that this coupled with the disproportionate removal of males and the introduction of new crops from the Americas ( cassava, maize) would have limited general population decline to particular regions of western Africa around 1760-1810, and in Mozambique and neighbouring areas half a century later. There has also been speculation that within Africa, females were most often captured as brides, with their male protectors being a "bycatch" who would have been killed if there had not been an export market for them.

British explorer Mungo Park encountered a group of slaves when traveling through Mandinka country:

They were all very inquisitive, but they viewed me at first with looks of horror, and repeatedly asked if my countrymen were cannibals. They were very desirous to know what became of the slaves after they had crossed the salt water. I told them that they were employed in cultivation the land; but they would not believe me ... A deeply-rooted idea that the whites purchase negroes for the purpose of devouring them, or of selling them to others that they may be devoured hereafter, naturally makes the slaves contemplate a journey towards the coast with great terror, insomuch that the slatees are forced to keep them constantly in irons, and watch them very closely, to prevent their escape.

During the period from the late 19th century and early 20th century, demand for the labour-intensive harvesting of rubber drove frontier expansion and forced labour. The personal monarchy of Belgian King Leopold II in the Congo Free State saw mass killings and slavery to extract rubber.

Stephanie Smallwood in her book Saltwater Slavery uses Equiano's account on board ships to describe the general thoughts of most slaves.

Then," said I, "how comes it in all our country we never heard of them?" They told me because they lived so very far off. I then asked where were their women? Had they any like themselves? I was told that they had. "And why," said I, "do we not see them?" They answered, because they were left behind. I asked how the vessel could go? They told me they could not tell; but that there was cloth put upon the masts by the help of the ropes I saw, and then the vessel went on; and the white men had some spell or magic they put in the water when they liked, in order to stop the vessel. I was exceedingly amazed at this account, and really thought they were spirits. I there-fore wished much to be from amongst them, for I expected they would sacrifice me; but my wishes were vain-for we were so quartered that it was impossible for any of us to make our escape.

Accounts like these raised many questions as some slaves grew philosophical with their journey. Smallwood points out the challenges for slaves were physical and metaphysical. The physical would be obvious as the challenge to overcome capacity, lack of ship room, and food. The metaphysical was unique as the open sea would challenge African slaves' vision of the ocean as habitable. At essence, the journey on the ocean would prove to be an African's biggest fear that would keep them in awe. Combining this with the lack of knowledge of the sea, Africans would be entering a world of anxiety never seen before. Yet, Europeans were also fearful of the sea, but not to the extent of Africans. One of these dilemmas came with the sense of time. Africans used seasonal weather to predict time and days. The moon was a sense of time, but used like in other cultures. On the sea, Africans used the moon to best count the days, but the sea did not provide seasonal changes for them to know how long they were at sea. Counting the days on a ship was not the main priority, however. Surviving the voyage was the main horror. No one escaped diseases as the close quarters infected everyone including the crew. Death was so common that ships were called tumbeiros or floating tombs. What shocked Africans the most was how death was handled in the ships. Smallwood says the traditions for an African death was delicate and community-based. On ships, bodies would be thrown into the sea. Because the sea represented bad omens, bodies in the sea represented a form of purgatory and the ship a form of hell. In the end, the Africans who made the journey would have survived disease, malnutrition, confined space, close death, and the trauma of the ship.

In Algiers during the time of the Regency of Algiers in North Africa in the 19th century, 1.5 million Christians and Europeans were captured and forced into slavery. This eventually led to the Bombardment of Algiers in 1816 by the British and Dutch, forcing the Dey of Algiers to free many slaves.

The trading of children has been reported in modern Nigeria and Benin. In parts of Ghana, a family may be punished for an offense by having to turn over a virgin female to serve as a sex slave within the offended family. In this instance, the woman does not gain the title or status of "wife". In parts of Ghana, Togo, and Benin, shrine slavery persists, despite being illegal in Ghana since 1998. In this system of ritual servitude, sometimes called trokosi (in Ghana) or voodoosi in Togo and Benin, young virgin girls are given as slaves to traditional shrines and are used sexually by the priests in addition to providing free labor for the shrine.

An article in the Middle East Quarterly in 1999 reported that slavery is endemic in Sudan. Estimates of abductions during the Second Sudanese Civil War range from 14,000 to 200,000 people.

During the Second Sudanese Civil War people were taken into slavery; estimates of abductions range from 14,000 to 200,000. Abduction of Dinka women and children was common. In Mauritania it is estimated that up to 600,000 men, women and children, or 20% of the population, are currently enslaved, many of them used as bonded labor. Slavery in Mauritania was criminalized in August 2007.

During the Darfur conflict that began in 2003, many people were kidnapped by Janjaweed and sold into slavery as agricultural labor, domestic servants and sex slaves.

In Niger, slavery is also a current phenomenon. A Nigerien study has found that more than 800,000 people are enslaved, almost 8% of the population. Niger installed an anti-slavery provision in 2003. In a landmark ruling in 2008, the ECOWAS Community Court of Justice declared that the Republic of Niger failed to protect Hadijatou Mani Koraou from slavery, and awarded Mani CFA 10,000,000 (approximately US$20,000) in reparations.

Sexual slavery and forced labor are common in the Democratic Republic of Congo.

Many pygmies in the Republic of Congo and Democratic Republic of Congo belong from birth to Bantus in a system of slavery.

Evidence emerged in the late 1990s of systematic slavery in cacao plantations in West Africa; see the chocolate and slavery article.

On the night of 14-15 April 2014, a group of militants attacked the Government Girls Secondary School in Chibok, Nigeria. They broke into the school, pretending to be guards, telling the girls to get out and come with them. A large number of students were taken away in trucks, possibly into the Konduga area of the Sambisa Forest where Boko Haram were known to have fortified camps. Houses in Chibok were also burned down in the incident. According to police, approximately 276 children were taken in the attack, of whom 53 had escaped as of 2 May. Other reports said that 329 girls were kidnapped, 53 had escaped and 276 were still missing. The students have been forced to convert to Islam and into marriage with members of Boko Haram, with a reputed " bride price" of ₦2,000 each ($12.50/ £7.50). Many of the students were taken to the neighbouring countries of Chad and Cameroon, with sightings reported of the students crossing borders with the militants, and sightings of the students by villagers living in the Sambisa Forest, which is considered a refuge for Boko Haram.

On 5 May 2014 a video in which Boko Haram leader Abubakar Shekau claimed responsibility for the kidnappings emerged. Shekau claimed that "Allah instructed me to sell them...I will carry out his instructions" and "[s]lavery is allowed in my religion, and I shall capture people and make them slaves." He said the girls should not have been in school and instead should have been married since girls as young as nine are suitable for marriage.

During the Second Libyan Civil War Libyans started capturing some of the Sub-Saharan African migrants trying to get to Europe through Libya and selling them on slave markets. Slaves are often ransomed to their families and in the meantime until ransom can be paid, they may be tortured, forced to work, sometimes worked to death, and eventually they may be executed or left to starve if the payment has not been made after a period of time. Women are often raped and used as sex slaves and sold to brothels.

Many child migrants also suffer from abuse and child rape in Libya.

In Pre-Columbian Mesoamerica the most common forms of slavery were those of prisoners of war and debtors. People unable to pay back debts could be sentenced to work as slaves to the persons owed until the debts were worked off. Warfare was important to Maya society, because raids on surrounding areas provided the victims required for human sacrifice, as well as slaves for the construction of temples. Most victims of human sacrifice were prisoners of war or slaves. Slavery was not usually hereditary; children of slaves were born free. In the Inca Empire, workers were subject to a in lieu of taxes which they paid by working for the government. Each , or extended family, would decide which family member to send to do the work. It is unclear if this labor draft or corvée counts as slavery. The Spanish adopted this system, particularly for their silver mines in Bolivia.

Other slave-owning societies and tribes of the New World were, for example, the Tehuelche of Patagonia, the Comanche of Texas, the Caribs of Dominica, the Tupinambá of Brazil, the fishing societies, such as the Yurok, that lived along the coast from what is now Alaska to California, the Pawnee and Klamath. Many of the indigenous peoples of the Pacific Northwest Coast, such as the Haida and Tlingit, were traditionally known as fierce warriors and slave-traders, raiding as far as California. Slavery was hereditary, the slaves being prisoners of war. Among some Pacific Northwest tribes about a quarter of the population were slaves. One slave narrative was composed by an Englishman, John R. Jewitt, who had been taken alive when his ship was captured in 1802; his memoir provides a detailed look at life as a slave, and asserts that a large number were held.

During the period from the late 19th century and early 20th century, demand for the labor-intensive harvesting of rubber drove frontier expansion and slavery in Latin America and elsewhere. Indigenous peoples were enslaved as part of the rubber boom in Ecuador, Peru, Colombia, and Brazil. In Central America, rubber tappers participated in the enslavement of the indigenous Guatuso-Maleku people for domestic service.

Slavery was a mainstay of the Brazilian colonial economy, especially in mining and sugarcane production. 35.3% of all slaves involved in the Atlantic Slave trade went to Brazil. 4 million slaves were obtained by Brazil, 1.5 million more than any other country. Starting around 1550, the Portuguese began to trade African slaves to work the sugar plantations, once the native Tupi people deteriorated. Although Portuguese Prime Minister Sebastião José de Carvalho e Melo, 1st Marquis of Pombal abolished slavery in mainland Portugal on 12 February 1761, slavery continued in her overseas colonies. Slavery was practiced among all classes. Slaves were owned by upper and middle classes, by the poor, and even by other slaves.

From São Paulo, the Bandeirantes, adventurers mostly of mixed Portuguese and native ancestry, penetrated steadily westward in their search for Indian slaves. Along the Amazon river and its major tributaries, repeated slaving raids and punitive attacks left their mark. One French traveler in the 1740s described hundreds of miles of river banks with no sign of human life and once-thriving villages that were devastated and empty. In some areas of the Amazon Basin, and particularly among the Guarani of southern Brazil and Paraguay, the Jesuits had organized their Jesuit Reductions along military lines to fight the slavers. In the mid-to-late 19th century, many Amerindians were enslaved to work on rubber plantations.

Escaped slaves formed Maroon communities which played an important role in the histories of Brazil and other countries such as Suriname, Puerto Rico, Cuba, and Jamaica. In Brazil, the Maroon villages were called palenques or quilombos. Maroons survived by growing vegetables and hunting. They also raided plantations. At these attacks, the maroons would burn crops, steal livestock and tools, kill slavemasters, and invite other slaves to join their communities.

Jean-Baptiste Debret, a French painter who was active in Brazil in the first decades of the 19th century, started out with painting portraits of members of the Brazilian Imperial family, but soon became concerned with the slavery of both blacks and indigenous inhabitants. His paintings on the subject (two appear on this page) helped bring attention to the subject in both Europe and Brazil itself.

The Clapham Sect, a group of evangelical reformers, campaigned during much of the 19th century for Britain to use its influence and power to stop the traffic of slaves to Brazil. Besides moral qualms, the low cost of slave-produced Brazilian sugar meant that British colonies in the West Indies were unable to match the market prices of Brazilian sugar, and each Briton was consuming 16 pounds (7 kg) of sugar a year by the 19th century. This combination led to intensive pressure from the British government for Brazil to end this practice, which it did by steps over several decades.

Brazil's 1877-78 Grande Seca (Great Drought) in the cotton-growing northeast led to major turmoil, starvation, poverty and internal migration. As wealthy plantation holders rushed to sell their slaves south, popular resistance and resentment grew, inspiring numerous emancipation societies. They succeeded in banning slavery altogether in the province of Ceará by 1884. Slavery was legally ended nationwide on 13 May by the ("Golden Law") of 1888. It was an institution in decadence at these times, as since the 1880s the country had begun to use European immigrant labor instead. Brazil was the last nation in the Western Hemisphere to abolish slavery.

Slavery was commonly used in the parts of the Caribbean controlled by France and the British Empire. The Lesser Antilles islands of Barbados, St. Kitts, Antigua, Martinique and Guadeloupe, which were the first important slave societies of the Caribbean, began the widespread use of African slaves by the end of the 17th century, as their economies converted from sugar production.

England had multiple sugar islands in the Caribbean, especially Jamaica, Barbados, Nevis, and Antigua, which provided a steady flow of sugar sales; slave labor produced the sugar. By the 1700s, there were more slaves in Barbados than all the colonies combined. Since Barbados did not have many mountains, the British were able to clear land for sugar cane. Indentured servants were initially sent to Barbados to work in the sugar fields. These indentured servants were treated so poorly that future indentured servants stopped going to Barbados, and there were not enough people to work the fields. This is when the British started bringing in African slaves. It was important for the slaves to be in Barbados because sugar had become a necessity for most people and the demand for it was high.

An important result of Britain's victory in the War of the Spanish Succession (1702-1714) was enlarging its role in the slave trade. Of special importance was the successful secret negotiation with France to obtain thirty-year monopoly on the Spanish slave trade, called the Queen Anne of Great Britain also allowed her North American colonies like Virginia to make laws that promoted black slavery. Anne had secretly negotiated with France to get its approval regarding the Asiento. She boasted to Parliament of her success in taking the Asiento away from France and London celebrated her economic coup. Most of the slave trade involved sales to Spanish colonies in the Caribbean, and to Mexico, as well as sales to British colonies in the Caribbean and in North America. Historian Vinita Ricks says the agreement allotted Queen Anne "22.5% (and King Philip V, of Spain 28%) of all profits collected for her personal fortune." Ricks concludes that the Queen's "connection to slave trade revenue meant that she was no longer a neutral observer. She had a vested interest in what happened on slave ships."

By 1778, the French were importing approximately 13,000 Africans for enslavement yearly to the French West Indies.

To regularise slavery, in 1685 Louis XIV had enacted the , which accorded certain human rights to slaves and responsibilities to the master, who was obliged to feed, clothe and provide for the general well-being of his slaves. Free blacks owned one-third of the plantation property and one-quarter of the slaves in Saint Domingue (later Haiti). Slavery in the French First Republic was abolished on 4 February 1794. When it became clear that Napoleon intended to re-establish slavery in Haiti, Dessalines and Pétion switched sides, in October 1802. On 1 January 1804, Jean-Jacques Dessalines, the new leader under the dictatorial 1801 constitution, declared Haiti a free republic. Thus Haiti became the second independent nation in the Western Hemisphere, after the United States, and the only successful slave rebellion in world history.

Whitehall in England announced in 1833 that slaves in its territories would be totally freed by 1840. In the meantime, the government told slaves they had to remain on their plantations and would have the status of "apprentices" for the next six years.

In Port-of-Spain, Trinidad, on 1 August 1834, an unarmed group of mainly elderly Negroes being addressed by the Governor at Government House about the new laws, began chanting: "Pas de six ans. Point de six ans" ("Not six years. No six years"), drowning out the voice of the Governor. Peaceful protests continued until a resolution to abolish apprenticeship was passed and de facto freedom was achieved. Full emancipation for all was legally granted ahead of schedule on 1 August 1838, making Trinidad the first British colony with slaves to completely abolish slavery.

In late August 1619, the frigate , a privateer ship owned by Robert Rich, 2nd Earl of Warwick, but flying a Dutch flag arrived at Point Comfort, Virginia (several miles downstream from the colony of Jamestown, Virginia) with the first recorded slaves from Africa to Virginia. The approximately 20 Africans were from the present-day Angola. They had been removed by the White Lion's crew from a Portuguese slave ship, the São João Bautista.

Only a fraction of the enslaved Africans brought to the New World came to British North America, perhaps as little as 5% of the total. The vast majority of slaves were sent to the Caribbean sugar colonies, Brazil, or Spanish America.

By the 1680s, with the consolidation of England's Royal African Company, enslaved Africans were arriving in English colonies in larger numbers, and the institution continued to be protected by the British government. Colonists now began purchasing slaves in larger numbers.

1640: Virginia courts sentence John Punch to lifetime slavery, marking the earliest legal sanctioning of slavery in English colonies.

1641: Massachusetts legalizes slavery.

1650: Connecticut legalizes slavery.

1654: Virginia sanctions "the right of Negros to own slaves of their own race" after African Anthony Johnson, former indentured servant, sued to have fellow African John Casor declared not an indentured servant but "slave for life."

1661: Virginia officially recognizes slavery by statute.

1662: A Virginia statute declares that children born would have the same status as their mother.

1663: Maryland legalizes slavery.

1664: Slavery is legalized in New York and New Jersey.

1670: Carolina (later, South Carolina and North Carolina) is founded mainly by planters from the overpopulated British sugar island colony of Barbados, who brought relatively large numbers of African slaves from that island.

The shift from indentured servants to African slaves was prompted by a dwindling class of former servants who had worked through the terms of their indentures and thus became competitors to their former masters. These newly freed servants were rarely able to support themselves comfortably, and the tobacco industry was increasingly dominated by large planters. This caused domestic unrest culminating in Bacon's Rebellion. Eventually, chattel slavery became the norm in regions dominated by plantations.

Several local slave rebellions took place during the 17th and 18th centuries: Gloucester County, Virginia Revolt (1663); New York Slave Revolt of 1712; Stono Rebellion (1739); and New York Slave Insurrection of 1741.

Within the British Empire, the Massachusetts courts began to follow England when, in 1772, England became the first country in the world to outlaw the slave trade within its borders (see Somerset v Stewart) followed by the Knight v. Wedderburn decision in Scotland in 1778. Between 1764 and 1774, seventeen slaves appeared in Massachusetts courts to sue their owners for freedom. In 1766, John Adams' colleague Benjamin Kent won the first trial in the present-day United States to free a slave (Slew vs. Whipple).

The Republic of Vermont banned slavery in its constitution of 1777 and continued the ban when it entered the United States in 1791. Through the Northwest Ordinance of 1787 under the Congress of the Confederation, slavery was prohibited in the territories north west of the Ohio River. By 1804, abolitionists succeeded in passing legislation that ended legal slavery in every northern state (with slaves above a certain age legally transformed to indentured servants). Congress banned the international importation or export of slaves on 1 January 1808; but not the internal slave trade.

Despite the actions of abolitionists, free blacks were subject to racial segregation in the Northern states. While England did not ban slavery in present-day Canada until 1833, free blacks found refugee and liberty there after the America Revolution and again after the War of 1812. Slavery in Canada was largely ended by judicial court decisions by the early nineteenth century. Refugees from slavery fled the South across the Ohio River to the North via the Underground Railroad. Midwestern state governments asserted States Rights arguments to refuse federal jurisdiction over fugitives. Some juries exercised their right of jury nullification and refused to convict those indicted under the Fugitive Slave Act of 1850.

After the passage of the Kansas-Nebraska Act in 1854, armed conflict broke out in Kansas Territory, where the question of whether it would be admitted to the Union as a slave state or a free state had been left to the inhabitants. The radical abolitionist John Brown was active in the mayhem and killing in " Bleeding Kansas." The true turning point in public opinion is better fixed at the Lecompton Constitution fraud. Pro-slavery elements in Kansas had arrived first from Missouri and quickly organized a territorial government that excluded abolitionists. Through the machinery of the territory and violence, the pro-slavery faction attempted to force an unpopular pro-slavery constitution through the state. This infuriated Northern Democrats, who supported popular sovereignty, and was exacerbated by the Buchanan administration reneging on a promise to submit the constitution to a referendum-which would surely fail. Anti-slavery legislators took office under the banner of the newly formed Republican Party. The Supreme Court in the Dred Scott decision of 1857 asserted that one could take one's property anywhere, even if one's property was chattel and one crossed into a free territory. It also asserted that African Americans could not be federal citizens. Outraged critics across the North denounced these episodes as the latest of the Slave Power (the politically organized slave owners) taking more control of the nation.

The slave population in the United States stood at four million. Ninety-five percent of blacks lived in the South, comprising one third of the population there as opposed to 1% of the population of the North. The central issue in politics in the 1850s involved the extension of slavery into the western territories, which settlers from the Northern states opposed. The Whig Party split and collapsed on the slavery issue, to be replaced in the North by the new Republican Party, which was dedicated to stopping the expansion of slavery. Republicans gained a majority in every northern state by absorbing a faction of anti-slavery Democrats, and warning that slavery was a backward system that undercut democracy and economic modernization. Numerous compromise proposals were put forward, but they all collapsed. A majority of Northern voters were committed to stopping the expansion of slavery, which they believed would ultimately end slavery. Southern voters were overwhelmingly angry that they were being treated as second-class citizens. In the election of 1860, the Republicans swept Abraham Lincoln into the Presidency and his party took control (with only 39.8% of the popular vote) and legislators into Congress. The states of the deep South, convinced that the economic power of what they called " King Cotton" would overwhelm the North and win support from Europe voted to seceded from the U.S. (the Union). They formed the Confederate States of America, based on the promise of maintaining slavery. War broke out in April 1861, as both sides sought wave after wave of enthusiasm among young men volunteering to form new regiments and new armies. In the North, the main goal was to preserve the union as an expression of American nationalism.

By 1862 most northern leaders realized that the mainstay of Southern secession, slavery, had to be attacked head-on. All the border states rejected President Lincoln's proposal for compensated emancipation. However, by 1865 all had begun the abolition of slavery, except Kentucky and Delaware. The Emancipation Proclamation was an executive order issued by Lincoln on 1 January 1863. In a single stroke, it changed the legal status, as recognized by the U.S. government, of 3 million slaves in designated areas of the Confederacy from "slave" to "free." It had the practical effect that as soon as a slave escaped the control of the Confederate government, by running away or through advances of federal troops, the slave became legally and actually free. Plantation owners, realizing that emancipation would destroy their economic system, sometimes moved their slaves as far as possible out of reach of the Union army. By June 1865, the Union Army controlled all of the Confederacy and liberated all of the designated slaves. The owners were never compensated. Over 200,000 free blacks and newly freed slaves fought for the Union in the Army and Navy, thereby validating their claims to full citizenship.

The severe dislocations of war and Reconstruction had a severe negative impact on the black population, with a large amount of sickness and death. After liberation, many of the Freedmen remained on the same plantation. Others fled or crowded into refugee camps operated by the Freedmen's Bureau. The Bureau provided food, housing, clothing, medical care, church services, some schooling, legal support, and arranged for labor contracts. Fierce debates about the rights of the Freedmen, and of the defeated Confederates, often accompanied by killings of black leaders, marked the Reconstruction Era, 1863-77.

Slavery was never reestablished, but after 1877, white Democrats took control of all the southern states and blacks lost nearly all the political power they had achieved during Reconstruction. By 1900 they also lost the right to vote. They had become second class citizens. The great majority lived in the rural South in poverty working as laborers, sharecroppers or tenant farmers; a small proportion owned their own land. The black churches, especially the Baptist Church, was the center of community activity and leadership.

Slavery in the Middle East first developed out of the slavery practices of the Ancient Near East, and these practices were radically different at times, depending on social-political factors such as the Arab slave trade. Two rough estimates by scholars of the number of slaves held over twelve centuries in Muslim lands are 11.5 million and 14 million.

Under Sharia (Islamic law), children of slaves or prisoners of war could become slaves but only non-Muslims. Manumission of a slave was encouraged as a way of expiating sins. Many early converts to Islam, such as Bilal ibn Rabah al-Habashi, were the poor and former slaves. In theory, slavery in Islamic law does not have a racial or color component, although this has not always been the case in practice.

Bernard Lewis writes: "In one of the sad paradoxes of human history, it was the humanitarian reforms brought by Islam that resulted in a vast development of the slave trade inside, and still more outside, the Islamic empire." He notes that the Islamic injunctions against the enslavement of Muslims led to massive importation of slaves from the outside. According to Patrick Manning, Islam by recognizing and codifying the slavery seems to have done more to protect and expand slavery than the reverse.

Slavery was a legal and important part of the economy of the Ottoman Empire and Ottoman society until the slavery of Caucasians was banned in the early 19th century, although slaves from other groups were allowed. In Constantinople (present-day Istanbul), the administrative and political center of the Empire, about a fifth of the population consisted of slaves in 1609. Even after several measures to ban slavery in the late 19th century, the practice continued largely unfazed into the early 20th century. As late as 1908, female slaves were still sold in the Ottoman Empire. Sexual slavery was a central part of the Ottoman slave system throughout the history of the institution.

A member of the Ottoman slave class, called a in Turkish, could achieve high status. Harem guards and janissaries are some of the better-known positions a slave could hold, but slaves were actually often at the forefront of Ottoman politics. The majority of officials in the Ottoman government were bought slaves, raised free, and integral to the success of the Ottoman Empire from the 14th century into the 19th. Many officials themselves owned a large number of slaves, although the Sultan himself owned by far the largest amount. By raising and specially training slaves as officials in palace schools such as Enderun, the Ottomans created administrators with intricate knowledge of government and fanatic loyalty.

Ottomans practiced , a sort of "blood tax" or "child collection", young Christian boys from the Balkans and Anatolia were taken from their homes and families, brought up as Muslims, and enlisted into the most famous branch of the , the Janissaries, a special soldier class of the Ottoman army that became a decisive faction in the Ottoman invasions of Europe.

During the various 18th and 19th century persecution campaigns against Christians as well as during the culminating Assyrian, Armenian and Greek genocides of World War I, many indigenous Armenian, Assyrian and Greek Christian women and children were carried off as slaves by the Ottoman Turks and their Kurdish allies. Henry Morgenthau, Sr., U.S. Ambassador in Constantinople from 1913 to 1916, reports in his Ambassador Morgenthau's Story that there were gangs trading white slaves during his term in Constantinople. He also reports that Armenian girls were sold as slaves during the Armenian Genocide.

The Arab or Islamic slave trade lasted much longer than the Atlantic or European slave trade: "It began in the middle of the seventh century and survives today in Mauritania and Sudan. With the Islamic slave trade, we're talking of 14 centuries rather than four." Further, "whereas the gender ratio of slaves in the Atlantic trade was two males to every female, in the Islamic trade, it was two females to every male," according to Ronald Segal

According to media reports from late 2014 the Islamic State of Iraq and the Levant (ISIL) was selling Yazidi and Christian women as slaves. According to Haleh Esfandiari of the Woodrow Wilson International Center for Scholars, after ISIL militants have captured an area "[t]hey usually take the older women to a makeshift slave market and try to sell them." In mid-October 2014, the UN estimated that 5,000 to 7,000 Yazidi women and children were abducted by ISIL and sold into slavery. In the digital magazine , ISIL claimed religious justification for enslaving Yazidi women whom they consider to be from a heretical sect. ISIL claimed that the Yazidi are idol worshipers and their enslavement is part of the old shariah practice of spoils of war. According to The Wall Street Journal, ISIL appeals to apocalyptic beliefs and claims "justification by a Hadith that they interpret as portraying the revival of slavery as a precursor to the end of the world".

ISIL announced the revival of slavery as an institution. In 2015 the official slave prices set by ISIL were following:

Children aged 1 to 9 were sold for 200,000 dinars ($169).

Women and children 10 to 20 years old for 150,000 dinars ($127).

Women 20 to 30 years old for 100,000 dinar ($85).

Women 30 to 40 years old are 75,000 dinar ($63).

Women 40 to 50 years old for 50,000 dinar ($42).

However some slaves have been sold for as little as a pack of cigarettes. Sex slaves were sold to Saudi Arabia, other Persian Gulf states and Turkey.

Slavery has existed all throughout Asia, and forms of slavery still exist today.

Scholars differ as to whether or not slaves and the institution of slavery existed in ancient India. These English words have no direct, universally accepted equivalent in Sanskrit or other Indian languages, but some scholars translate the word , mentioned in texts like Manu Smriti, as slaves. Ancient historians who visited India offer the closest insights into the nature of Indian society and slavery in other ancient civilizations. For example, the Greek historian Arrian, who chronicled India about the time of Alexander the Great, wrote in his Indika,

The Indians do not even use aliens as slaves, much less a countryman of their own.

Qin dynasty (221-206 BC) Men sentenced to castration became eunuch slaves of the Qin dynasty state and as a result they were made to do forced labor, on projects like the Terracotta Army. The Qin government confiscated the property and enslaved the families of those who received castration as a punishment for rape.
Slaves were deprived of their rights and connections to their families.

Han dynasty (206 BC - 220 AD) One of Emperor Gao's first acts was to set free from slavery agricultural workers who were enslaved during the Warring States period, although domestic servants retained their status.

Men punished with castration during the Han dynasty were also used as slave labor.

Deriving from earlier Legalist laws, the Han dynasty set in place rules that the property of and families of criminals doing three years of hard labor or sentenced to castration were to have their families seized and kept as property by the government.

During the millennium long Chinese domination of Vietnam, Vietnam was a great source of slave girls who were used as sex slaves in China. The slave girls of Viet were even eroticized in Tang dynasty poetry.

The Islamic invasions, starting in the 8th century, also resulted in hundreds of thousands of Indians being enslaved by the invading armies, one of the earliest being the armies of the Umayyad commander Muhammad bin Qasim. Qutb-ud-din Aybak, a Turkic slave of Muhammad Ghori rose to power following his master's death. For almost a century, his descendants ruled North-Central India in form of Slave Dynasty. Several slaves were also brought to India by the Indian Ocean trades; for example, the Siddi are descendants of Bantu slaves brought to India by Arab and Portuguese merchants.

Andre Wink summarizes the slavery in 8th and 9th century India as follows,

(During the invasion of Muhammad al-Qasim), invariably numerous women and children were enslaved. The sources insist that now, in dutiful conformity to religious law, 'the one-fifth of the slaves and spoils' were set apart for the caliph's treasury and despatched to Iraq and Syria. The remainder was scattered among the army of Islam. At Rūr, a random 60,000 captives reduced to slavery. At Brahamanabad 30,000 slaves were allegedly taken. At Multan 6,000. Slave raids continued to be made throughout the late Umayyad period in Sindh, but also much further into Hind, as far as Ujjain and Malwa. The Abbasid governors raided Punjab, where many prisoners and slaves were taken.

In the early 11th century Tarikh al-Yamini, the Arab historian Al-Utbi recorded that in 1001 the armies of Mahmud of Ghazna conquered Peshawar and Waihand (capital of Gandhara) after Battle of Peshawar (1001), "in the midst of the land of Hindustan", and captured some 100,000 youths. Later, following his twelfth expedition into India in 1018-19, Mahmud is reported to have returned with such a large number of slaves that their value was reduced to only two to ten dirhams each. This unusually low price made, according to Al-Utbi, "merchants [come] from distant cities to purchase them, so that the countries of Central Asia, Iraq and Khurasan were swelled with them, and the fair and the dark, the rich and the poor, mingled in one common slavery". Elliot and Dowson refer to "five hundred thousand slaves, beautiful men and women.". Later, during the Delhi Sultanate period (1206-1555), references to the abundant availability of low-priced Indian slaves abound. Levi attributes this primarily to the vast human resources of India, compared to its neighbors to the north and west (India's Mughal population being approximately 12 to 20 times that of Turan and Iran at the end of the 16th century).

Slavery and empire-formation tied in particularly well with iqta and it is within this context of Islamic expansion that elite slavery was later commonly found. It became the predominant system in North India in the thirteenth century and retained considerable importance in the fourteenth century. Slavery was still vigorous in fifteenth-century Bengal, while after that date it shifted to the Deccan where it persisted until the seventeenth century. It remained present to a minor extent in the Mughal provinces throughout the seventeenth century and had a notable revival under the Afghans in North India again in the eighteenth century.

The Delhi sultanate obtained thousands of slaves and eunuch servants from the villages of Eastern Bengal (a widespread practice which Mughal emperor Jahangir later tried to stop). Wars, famines, pestilences drove many villagers to sell their children as slaves. The Muslim conquest of Gujarat in Western India had two main objectives. The conquerors demanded and more often forcibly wrested both land owned by Hindus and Hindu women. Enslavement of women invariably led to their conversion to Islam. In battles waged by Muslims against Hindus in Malwa and Deccan plateau, a large number of captives were taken. Muslim soldiers were permitted to retain and enslave POWs as plunder.

The first Bahmani sultan, Alauddin Bahman Shah is noted to have captured 1,000 singing and dancing girls from Hindu temples after he battled the northern Carnatic chieftains. The later Bahmanis also enslaved civilian women and children in wars; many of them were converted to Islam in captivity. About the Mughal empire, W.H. Moreland observed, "it became a fashion to raid a village or group of villages without any obvious justification, and carry off the inhabitants as slaves."

During the rule of Shah Jahan, many peasants were compelled to sell their women and children into slavery to meet the land revenue demand. Slavery was officially abolished in British India by the Indian Slavery Act, 1843. However, in modern India, Pakistan and Nepal, there are millions of bonded laborers, who work as slaves to pay off debts.

The Tang dynasty purchased Western slaves from the Radanite Jews. Tang Chinese soldiers and pirates enslaved Koreans, Turks, Persians, Indonesians, and people from Inner Mongolia, Central Asia, and northern India. The greatest source of slaves came from southern tribes, including Thais and aboriginals from the southern provinces of Fujian, Guangdong, Guangxi, and Guizhou. Malays, Khmers, Indians, and black Africans were also purchased as slaves in the Tang dynasty. Slavery was prevalent until the late 19th century and early 20th century China. All forms of slavery have been illegal in China since 1910.

Slavery in Japan was, for most of its history, indigenous, since the export and import of slaves was restricted by Japan being a group of islands. In late-16th-century Japan, slavery was officially banned; but forms of contract and indentured labor persisted alongside the period penal codes' forced labor. During the Second Sino-Japanese War and the Pacific War, the Japanese military used millions of civilians and prisoners of war from several countries as forced laborers.

In Korea, slavery was officially abolished with the Gabo Reform of 1894. During the Joseon period, in times of poor harvest and famine, many peasants voluntarily sold themselves into the nobi system in order to survive.

In Southeast Asia, there was a large slave class in Khmer Empire who built the enduring monuments in Angkor Wat and did most of the heavy work. Between the 17th and the early 20th centuries one-quarter to one-third of the population of some areas of Thailand and Burma were slaves. By the 19th century, Bhutan had developed a slave trade with Sikkim and Tibet, also enslaving British subjects and Brahmins. According to the International Labour Organization (ILO), during the early 21st century an estimated 800,000 people are subject to forced labor in Myanmar.

Slavery in pre-Spanish Philippines was practiced by the tribal Austronesian peoples who inhabited the culturally diverse islands. The neighbouring Muslim states conducted slave raids from the 1600s into the 1800s in coastal areas of the Gulf of Thailand and the Philippine islands. Slaves in Toraja society in Indonesia were family property. People would become slaves when they incurred a debt. Slaves could also be taken during wars, and slave trading was common. Torajan slaves were sold and shipped out to Java and Siam. Slaves could buy their freedom, but their children still inherited slave status. Slavery was abolished in 1863 in all Dutch colonies.

Records of slavery in Ancient Greece go as far back as Mycenaean Greece. The origins are not known, but it appears that slavery became an important part of the economy and society only after the establishment of cities. Slavery was common practice and an integral component of ancient Greece, as it was in other societies of the time, including ancient Israel. It is estimated that in Athens, the majority of citizens owned at least one slave. Most ancient writers considered slavery not only natural but necessary, but some isolated debate began to appear, notably in Socratic dialogues. The Stoics produced the first condemnation of slavery recorded in history.

During the 8th and the 7th centuries BC, in the course of the two Messenian Wars, the Spartans reduced an entire population to a pseudo-slavery called . According to Herodotus (IX, 28-29), helots were seven times as numerous as Spartans. Following several helot revolts around the year 600 BC, the Spartans restructured their city-state along authoritarian lines, for the leaders decided that only by turning their society into an armed camp could they hope to maintain control over the numerically dominant helot population. In some Ancient Greek city-states, about 30% of the population consisted of slaves, but paid and slave labor seem to have been equally important.

Romans inherited the institution of slavery from the Greeks and the Phoenicians. As the Roman Republic expanded outward, it enslaved entire populations, thus ensuring an ample supply of laborers to work in Rome's farms, quarries and households. The people subjected to Roman slavery came from all over Europe and the Mediterranean. Such oppression by an elite minority eventually led to slave revolts; the Third Servile War led by Spartacus was the most famous and severe. Greeks, Berbers, Germans, Britons, Slavs, Thracians, Gauls (or Celts), Jews, Arabs and many more ethnic groups were enslaved to be used for labor, and also for amusement (e.g. gladiators and sex slaves). If a slave ran away, they were liable to be crucified.

The overall impact of slavery on the Italian genetics was insignificant though, because the slaves imported in Italy were native Europeans, and very few if any of them had extra European origin. This has been further confirmed by recent biochemical analysis of 166 skeletons from three non-elite imperial-era cemeteries in the vicinity of Rome (where the bulk of the slaves lived), which shows that only 1 individual definitely came from outside of Europe (North Africa), and another 2 possibly did, but results are inconclusive. In the rest of the Italian peninsula, the amount of non European slaves was definitively much lower than that.

The chaos of invasion and frequent warfare also resulted in victorious parties taking slaves throughout Europe in the early Middle Ages. St. Patrick, himself captured and sold as a slave, protested against an attack that enslaved newly baptized Christians in his "Letter to the Soldiers of Coroticus". As a commonly traded commodity, like cattle, slaves could become a form of internal or trans-border currency. Slavery during the Early Middle Ages had several distinct sources.

The Vikings raided across Europe, but took the most slaves in raids on the British Isles and in Eastern Europe. While the Vikings kept some slaves as servants, known as , they sold most captives in the Byzantine or Islamic markets. In the West, their target populations were primarily English, Irish, and Scottish, while in the East they were mainly Slavs. The Viking slave-trade slowly ended in the 11th century, as the Vikings settled in the European territories they had once raided. They converted serfs to Christianity and themselves merged with the local populace.

In central Europe, specifically the Frankish/German/Holy Roman Empire of Charlemagne, raids and wars to the east generated a steady supply of slaves from the Slavic captives of these regions. Because of high demand for slaves in the wealthy Muslim empires of Northern Africa, Spain, and the Near East, especially for slaves of European descent, a market for these slaves rapidly emerged. So lucrative was this market that it spawned an economic boom in central and western Europe, today known as the Carolingian Renaissance. This boom period for slaves stretched from the early Muslim conquests to the High Middle Ages but declined in the later Middle Ages as the Islamic Golden Age waned.

Medieval Spain and Portugal saw almost constant warfare between Muslims and Christians. Al-Andalus sent periodic raiding expeditions to loot the Iberian Christian kingdoms, bringing back booty and slaves. In a raid against Lisbon, Portugal in 1189, for example, the Almohad caliph Yaqub al-Mansur took 3,000 female and child captives. In a subsequent attack upon Silves, Portugal in 1191, his governor of Córdoba took 3,000 Christian slaves.

The Byzantine-Ottoman wars and the Ottoman wars in Europe resulted in the taking of large numbers of Christian slaves and using or selling them in the Islamic world too. After the battle of Lepanto the victors freed approximately 12,000 Christian galley slaves from the Ottoman fleet.

Similarly, Christians sold Muslim slaves captured in war. The Order of the Knights of Malta attacked pirates and Muslim shipping, and their base became a centre for slave trading, selling captured North Africans and Turks. Malta remained a slave market until well into the late 18th century. One thousand slaves were required to man the galleys (ships) of the Order.

Poland banned slavery in the 15th century; in Lithuania, slavery was formally abolished in 1588; the institution was replaced by the second enserfment. Slavery remained a minor institution in Russia until 1723, when Peter the Great converted the household slaves into house serfs. Russian agricultural slaves were formally converted into serfs earlier, in 1679. The escaped Russian serfs and kholops formed autonomous communities in the southern steppes, where they became known as Cossacks (meaning "outlaws").

Capture in war, voluntary servitude and debt slavery became common within the British Isles before 1066. Slaves were routinely bought and sold. Running away was also common and slavery was never a major economic factor in the British Isles during the Middle Ages. Ireland and Denmark provided markets for captured Anglo-Saxon and Celtic slaves. Pope Gregory I reputedly made the pun, Non Angli, sed Angeli ("Not Angles, but Angels"), after a response to his query regarding the identity of a group of fair-haired Angles, slave children whom he had observed in the marketplace. After the Norman Conquest, the law no longer supported chattel slavery and slaves became part of the larger body of serfs.

Barbary pirates and Maltese corsairs both raided for slaves and purchased slaves from European merchants, often the Radhanites, one of the few groups who could easily move between the Christian and Islamic worlds.

In the late Middle Ages, from 1100 to 1500, the European slave-trade continued, though with a shift from being centered among the Western Mediterranean Islamic nations to the Eastern Christian and Muslim states. The city-states of Venice and Genoa controlled the Eastern Mediterranean from the 12th century and the Black Sea from the 13th century. They sold both Slavic and Baltic slaves, as well as Georgians, Turks, and other ethnic groups of the Black Sea and Caucasus. The sale of European slaves by Europeans slowly ended as the Slavic and Baltic ethnic groups Christianized by the Late Middle Ages. European slaves did not pass on an inherited status and was thus more akin to forced labor, or indentured servitude.

From the 1440s into the 18th century, Europeans from Italy, Spain, Portugal, France, and England were sold into slavery by North Africans, as described in the book "Christian Slaves, Muslim Masters". This same book states that "white slavery had been minimised or ignored because academics preferred to treat Europeans as evil colonialists rather than as victims." and likely overestimates the number of slaves taken. In 1575, the Tatars captured over 35,000 Ukrainians; a 1676 raid took almost 40,000. About 60,000 Ukrainians were captured in 1688; some were ransomed, but most were sold into slavery. Some of the Roma people were enslaved over five centuries in Romania until abolition in 1864 (see Slavery in Romania).

The Mongol invasions and conquests in the 13th century also resulted in taking numerous captives into slavery. The Mongols enslaved skilled individuals, women and children and marched them to Karakorum or Sarai, whence they were sold throughout Eurasia. Many of these slaves were shipped to the slave market in Novgorod.

Slave commerce during the Late Middle Ages was mainly in the hands of Venetian and Genoese merchants and cartels, who were involved in the slave trade with the Golden Horde. In 1382 the Golden Horde under Khan Tokhtamysh sacked Moscow, burning the city and carrying off thousands of inhabitants as slaves. Between 1414 and 1423, some 10,000 eastern European slaves were sold in Venice. Genoese merchants organized the slave trade from the Crimea to Mamluk Egypt. For years, the Khanates of Kazan and Astrakhan routinely made raids on Russian principalities for slaves and to plunder towns. Russian chronicles record about 40 raids by Kazan Khans on the Russian territories in the first half of the 16th century.

In 1441 Haci I Giray declared independence from the Golden Horde and established the Crimean Khanate. For a long time, until the early 18th century, the khanate maintained an extensive slave-trade with the Ottoman Empire and the Middle East. In a process called the "harvesting of the steppe" they enslaved many Slavic peasants. About 30 major Tatar raids were recorded into Muscovite territories between 1558 and 1596.

Moscow was repeatedly a target. In 1521, the combined forces of Crimean Khan Mehmed Giray and his Kazan allies attacked the city and captured thousands of slaves. In 1571, the Crimean Tatars attacked and sacked Moscow, burning everything but the Kremlin and taking thousands of captives as slaves. In Crimea, about 75% of the population consisted of slaves.

In the Viking era beginning circa 793, the Norse raiders often captured and enslaved militarily weaker peoples they encountered. The Nordic countries called their slaves ( Old Norse: Þræll). The thralls were mostly from Western Europe, among them many Franks, Frisians, Anglo-Saxons, and both Irish and Britonnic Celts. Many Irish slaves travelled in expeditions for the colonization of Iceland. The Norse also took German, Baltic, Slavic and Latin slaves. The slave trade was one of the pillars of Norse commerce during the 6th through 11th centuries. The 10th-century Persian traveller Ibn Rustah described how Swedish Vikings, the Varangians or Rus, terrorized and enslaved the Slavs taken in their raids along the Volga River. The thrall system was finally abolished in the mid-14th century in Scandinavia.

Mediterranean powers frequently sentenced convicted criminals to row in the war- galleys of the state (initially only in time of war). After the revocation of the Edict of Nantes in 1685 and Camisard rebellion, the French Crown filled its galleys with French Huguenots, Protestants condemned for resisting the state. Galley-slaves lived and worked in such harsh conditions that many did not survive their terms of sentence, even if they survived shipwreck and slaughter or torture at the hands of enemies or of pirates. Naval forces often turned 'infidel' prisoners-of-war into galley-slaves. Several well-known historical figures served time as galley slaves after being captured by the enemy-the Ottoman corsair and admiral Turgut Reis and the Knights Hospitaller Grand Master Jean Parisot de la Valette among them.

Denmark-Norway was the first European country to ban the slave trade. This happened with a decree issued by King Christian VII of Denmark in 1792, to become fully effective by 1803. Slavery as an institution was not banned until 1848. At this time Iceland was a part of Denmark-Norway but slave trading had been abolished in Iceland in 1117 and had never been reestablished.

Slavery in the French Republic was abolished on 4 February 1794, including in its colonies. The lengthy Haitian Revolution by its slaves and free people of color established Haiti as a free republic in 1804 ruled by blacks, the first of its kind. At the time of the revolution, Haiti was known as Saint-Domingue and was a colony of France. Napoleon Bonaparte gave up on Haiti in 1803, but re-established slavery in Guadeloupe and Martinique in 1804, at the request of planters of the Caribbean colonies. Slavery was permanently abolished in the French empire during the French Revolution of 1848.

The 15th-century Portuguese exploration of the African coast is commonly regarded as the harbinger of European colonialism. In 1452, Pope Nicholas V issued the papal bull Dum Diversas, granting Afonso V of Portugal the right to reduce any "Saracens, pagans and any other unbelievers" to hereditary slavery which legitimized slave trade under Catholic beliefs of that time. This approval of slavery was reaffirmed and extended in his Romanus Pontifex bull of 1455. These papal bulls came to serve as a justification for the subsequent era of the slave trade and European colonialism. Although for a short period as in 1462, Pius II declared slavery to be "a great crime". The followers of the church of England and Protestants did not use the papal bull as a justification. The position of the church was to condemn the slavery of Christians, but slavery was regarded as an old established and necessary institution which supplied Europe with the necessary workforce. In the 16th century, African slaves had replaced almost all other ethnicities and religious enslaved groups in Europe. Within the Portuguese territory of Brazil, and even beyond its original borders, the enslavement of Native Americans was carried out by the Bandeirantes.

Among many other European slave markets, Genoa, and Venice were some well-known markets, their importance and demand growing after the great plague of the 14th century which decimated much of the European workforce. The maritime town of Lagos, Portugal, was the first slave market created in Portugal for the sale of imported African slaves, the Mercado de Escravos, which opened in 1444. In 1441, the first slaves were brought to Portugal from northern Mauritania. Prince Henry the Navigator, major sponsor of the Portuguese African expeditions, as of any other merchandise, taxed one fifth of the selling price of the slaves imported to Portugal. By the year 1552 African slaves made up 10 percent of the population of Lisbon. In the second half of the 16th century, the Crown gave up the monopoly on slave trade and the focus of European trade in African slaves shifted from import to Europe to slave transports directly to tropical colonies in the Americas-in the case of Portugal, especially Brazil. In the 15th century, one-third of the slaves were resold to the African market in exchange of gold. Slavery was abolished in mainland Portugal and Portuguese India in 1761. It was finally abolished in all Portuguese colonies in 1869.

The Spaniards were the first Europeans to use African slaves in the New World on islands such as Cuba and Hispaniola, due to a shortage of labor caused by the spread of diseases, and so the Spanish colonists gradually became involved in the Atlantic slave trade. The first African slaves arrived in Hispaniola in 1501; by 1517, the natives had been "virtually annihilated" mostly to diseases. The problem of the justness of Native American's slavery was a key issue for the Spanish Crown. It was Charles V who gave a definite answer to this complicated and delicate matter. To that end, on 25 November 1542, the Emperor abolished slavery by decree in his Leyes Nuevas New Laws. This bill was based on the arguments given by the best Spanish theologists and jurists who were unanimous in the condemnation of such slavery as unjust; they declared it illegitimate and outlawed it from America-not just the slavery of Spaniards over Natives-but also the type of slavery practiced among the Natives themselves Thus, Spain became the first country to officially abolish slavery.

However, in the Spanish colonies of Cuba and Puerto Rico, where sugarcane production was highly profitable based on slave labor, African slavery persisted until 1873 in Puerto Rico "with provisions for periods of apprenticeship", and 1886 in Cuba.

Although slavery was illegal inside the Netherlands it flourished throughout the Dutch Empire in the Americas, Africa, Ceylon and Indonesia. The Dutch Slave Coast ( Dutch: Slavenkust) referred to the trading posts of the Dutch West India Company on the Slave Coast, which lie in contemporary Ghana, Benin, Togo and Nigeria. Initially the Dutch shipped slaves to northern Brazil, and during the second half of the 17th century they had a controlling interest in the trade to the Spanish colonies. Today's Suriname and Guyana became prominent markets in the 18th century. Between 1612 and 1872, the Dutch operated from some 10 fortresses along the Gold Coast (now Ghana), from which slaves were shipped across the Atlantic. Dutch involvement on the Slave Coast increased with the establishment of a trading post in Offra in 1660. Willem Bosman writes in his Nauwkeurige beschrijving van de Guinese Goud- Tand- en Slavekust (1703) that Allada was also called Grand Ardra, being the larger cousin of Little Ardra, also known as Offra. From 1660 onward, Dutch presence in Allada and especially Offra became more permanent. A report from this year asserts Dutch trading posts, apart from Allada and Offra, in Benin City, Grand-Popo, and Savi.

The Offra trading post soon became the most important Dutch office on the Slave Coast. According to a 1670 report, annually 2,500 to 3,000 slaves were transported from Offra to the Americas. These numbers were only feasible in times of peace, however, and dwindled in time of conflict. From 1688 onward, the struggle between the Aja king of Allada and the peoples on the coastal regions, impeded the supply of slaves. The Dutch West India Company chose the side of the Aja king, causing the Offra office to be destroyed by opposing forces in 1692. By 1650 the Dutch had the pre-eminent slave trade in Europe and South East Asia. Later, trade shifted to Ouidah. On the instigation of Governor-General of the Dutch Gold Coast Willem de la Palma, Jacob van den Broucke was sent in 1703 as "opperkommies" (head merchant) to the Dutch trading post at Ouidah, which according to sources was established around 1670. Political unrest caused the Dutch to abandon their trading post at Ouidah in 1725, and they then moved to Jaquim, at which place they built Fort Zeelandia. The head of the post, Hendrik Hertog, had a reputation for being a successful slave trader. In an attempt to extend his trading area, Hertog negotiated with local tribes and mingled in local political struggles. He sided with the wrong party, however, leading to a conflict with Director-General Jan Pranger and to his exile to the island of Appa in 1732. The Dutch trading post on this island was extended as the new centre of the slave trade. In 1733, Hertog returned to Jaquim, this time extending the trading post into Fort Zeelandia. The revival of the slave trade at Jaquim was only temporary, however, as his superiors at the Dutch West India Company noticed that Hertog's slaves were more expensive than at the Gold Coast. From 1735, Elmina became the preferred spot to trade slaves. As of 1778, it was estimated that the Dutch were shipping approximately 6,000 Africans for enslavement in the Dutch West Indies each year. Slavery also characterised the Dutch possessions in Indonesia, Ceylon and South Africa, where Indonesians have made a significant contribution to the Cape Coloured population of that country. The Dutch part in the Atlantic slave trade is estimated at 5-7 percent, as they shipped about 550,000-600,000 African slaves across the Atlantic, about 75,000 of whom died on board before reaching their destinations. From 1596 to 1829, the Dutch traders sold 250,000 slaves in the Dutch Guianas, 142,000 in the Dutch Caribbean islands, and 28,000 in Dutch Brazil. In addition, tens of thousands of slaves, mostly from India and some from Africa, were carried to the Dutch East Indies. The Netherlands was one of the last countries to abolish slavery in 1863. Although the decision was made in 1848, it took many years for the law to be implemented. Furthermore, slaves in Suriname would be fully free only in 1873, since the law stipulated that there was to be a mandatory 10-year transition.

Barbary Corsairs continued to trade in European slaves into the Modern time-period. Muslim pirates, primarily Algerians with the support of the Ottoman Empire, raided European coasts and shipping from the 16th to the 19th centuries, and took thousands of captives, whom they sold or enslaved. Many were held for ransom, and European communities raised funds such as Malta's Monte della Redenzione degli Schiavi to buy back their citizens. The raids gradually ended with the naval decline of the Ottoman Empire in the late 16th and 17th centuries, as well as the European conquest of North Africa throughout the 19th century.

From 1609 to 1616, England lost 466 merchant ships to Barbary pirates. 160 English ships were captured by Algerians between 1677 and 1680. Many of the captured sailors were made into slaves and held for ransom. The corsairs were no strangers to the South West of England where raids were known in a number of coastal communities. In 1627 Barbary Pirates under command of the Dutch renegade Jan Janszoon (Murat Reis), operating from the Moroccan port of Salé, occupied the island of Lundy. During this time there were reports of captured slaves being sent to Algiers.

Ireland, despite its northern position, was not immune from attacks by the corsairs. In June 1631 Janszoon, with pirates from Algiers and armed troops of the Ottoman Empire, stormed ashore at the little harbor village of Baltimore, County Cork. They captured almost all the villagers and took them away to a life of slavery in North Africa. The prisoners were destined for a variety of fates-some lived out their days chained to the oars as galley slaves, while others would spend long years in the scented seclusion of the harem or within the walls of the sultan's palace. Only two of them ever saw Ireland again.

The Congress of Vienna (1814-15), which ended the Napoleonic Wars, led to increased European consensus on the need to end Barbary raiding. The sacking of Palma on the island of Sardinia by a Tunisian squadron, which carried off 158 inhabitants, roused widespread indignation. Britain had by this time banned the slave trade and was seeking to induce other countries to do likewise. States that were more vulnerable to the corsairs complained that Britain cared more for ending the trade in African slaves than stopping the enslavement of Europeans and Americans by the Barbary States.

In order to neutralise this objection and further the anti-slavery campaign, in 1816 Britain sent Lord Exmouth to secure new concessions from Tripoli, Tunis, and Algiers, including a pledge to treat Christian captives in any future conflict as prisoners of war rather than slaves. He imposed peace between Algiers and the kingdoms of Sardinia and Sicily. On his first visit, Lord Exmouth negotiated satisfactory treaties and sailed for home. While he was negotiating, a number of Sardinian fishermen who had settled at Bona on the Tunisian coast were brutally treated without his knowledge. As Sardinians they were technically under British protection, and the government sent Exmouth back to secure reparation. On 17 August, in combination with a Dutch squadron under Admiral Van de Capellen, Exmouth bombarded Algiers. Both Algiers and Tunis made fresh concessions as a result.

The Barbary states had difficulty securing uniform compliance with a total prohibition of slave-raiding, as this had been traditionally of central importance to the North African economy. Slavers continued to take captives by preying on less well-protected peoples. Algiers subsequently renewed its slave-raiding, though on a smaller scale. Europeans at the Congress of Aix-la-Chapelle in 1818 discussed possible retaliation. In 1820 a British fleet under Admiral Sir Harry Neal bombarded Algiers. Corsair activity based in Algiers did not entirely cease until France conquered the state in 1830.

The Crimeans frequently mounted raids into the Danubian principalities, Poland-Lithuania, and Muscovy to enslave people whom they could capture; for each captive, the khan received a fixed share (savğa) of 10% or 20%. These campaigns by Crimean forces were either sefers ("sojourns" - officially declared military operations led by the khans themselves), or çapuls ("despoiling" - raids undertaken by groups of noblemen, sometimes illegally because they contravened treaties concluded by the khans with neighbouring rulers).

For a long time, until the early 18th century, the Crimean Khanate maintained a massive slave trade with the Ottoman Empire and the Middle East, exporting about 2 million slaves from Russia and Poland-Lithuania over the period 1500-1700. Caffa (modern Feodosia) became one of the best-known and significant trading ports and slave markets. In 1769 the last major Tatar raid saw the capture of 20,000 Russian and Ruthenian slaves.

Author and historian Brian Glyn Williams writes:

Fisher estimates that in the sixteenth century the Polish-Lithuanian Commonwealth lost around 20,000 individuals a year and that from 1474 to 1694, as many as a million Commonwealth citizens were carried off into Crimean slavery.

Early modern sources are full of descriptions of sufferings of Christian slaves captured by the Crimean Tatars in the course of their raids:

It seems that the position and everyday conditions of a slave depended largely on his/her owner. Some slaves indeed could spend the rest of their days doing exhausting labor: as the Crimean vizir (minister) Sefer Gazi Aga mentions in one of his letters, the slaves were often "a plough and a scythe" of their owners. Most terrible, perhaps, was the fate of those who became galley-slaves, whose sufferings were poeticized in many Ukrainian dumas (songs). ... Both female and male slaves were often used for sexual purposes.

Britain played a prominent role in the Atlantic slave trade, especially after 1640, when sugar cane was introduced to the region. At first, most were white Britons, or Irish, enslaved as indentured labour - for a fixed period - in the West Indies. These people may have been criminals, political rebels, the poor with no prospects or others who were simply tricked or kidnapped. Slavery was a legal institution in all of the 13 American colonies and Canada (acquired by Britain in 1763). The profits of the slave trade and of West Indian plantations amounted to 5% of the British economy at the time of the Industrial Revolution.

A little-known incident in the career of Judge Jeffreys refers to an assize in Bristol in 1685 when he made the mayor of the city, then sitting fully robed beside him on the bench, go into the dock and be fined £1000 for being a 'kidnapping knave'; some Bristol traders at the time were known at the time to kidnap their own countrymen and ship them away as slaves.

Somersett's case in 1772 was generally taken at the time to have decided that the condition of slavery did not exist under English law in England. In 1785, English poet William Cowper wrote: "We have no slaves at home - Then why abroad? Slaves cannot breathe in England; if their lungs receive our air, that moment they are free. They touch our country, and their shackles fall. That's noble, and bespeaks a nation proud. And jealous of the blessing. Spread it then, And let it circulate through every vein." However, slavery continued to thrive in England itself, much like it did in the British Empire, until full emancipation in the 1830s. In 1807, following many years of lobbying by the abolitionist movement, led primarily by William Wilberforce, the British Parliament voted to make the slave trade illegal anywhere in the Empire with the Slave Trade Act 1807. Thereafter Britain took a prominent role in combating the trade, and slavery itself was abolished in the British Empire (except for India) with the Slavery Abolition Act 1833. Between 1808 and 1860, the West Africa Squadron seized approximately 1,600 slave ships and freed 150,000 Africans who were aboard. Action was also taken against African leaders who refused to agree to British treaties to outlaw the trade. Akitoye, the 11th Oba of Lagos, is famous for having used British involvement to regain his rule in return for suppressing slavery among the Yoruba people of Lagos in 1851. Anti-slavery treaties were signed with over 50 African rulers. In 1839, the world's oldest international human rights organization, Anti-Slavery International, was formed in Britain by Joseph Sturge, which worked to outlaw slavery in other countries.

After 1833, the freed African slaves declined employment in the cane fields. This led to the importation of indentured labour again - mainly from India, and also China.

In 1811, Arthur William Hodge was executed for the murder of a slave in the British West Indies. He was not, however, as some have claimed, the first white person to have been lawfully executed for the murder of a slave.

During World War II Nazi Germany operated several categories of Arbeitslager (Labor Camps) for different categories of inmates. The largest number of them held Polish and Jewish civilians forcibly abducted in the occupied countries (see Łapanka) to provide labor in the German war industry, repair bombed railroads and bridges or work on farms. By 1944, 20% of all workers were foreigners, either civilians or prisoners of war.

This is not classed as slavery per se, as defined in the first paragraph, i.e. slavery under this definition does not include other forced labour systems, such as historical forced labor by prisoners, labor camps, or other forms of unfree labor, in which labourers are not legally considered property. Slavery typically requires a shortage of labor and a surplus of land to be viable.

As agreed by the Allies at the Yalta conference Germans were used as forced labor as part of the reparations to be extracted. By 1947 it is estimated that 400,000 Germans (both civilians and POWs) were being used as forced labor by the U.S., France, the UK and the Soviet Union. German prisoners were for example forced to clear minefields in France and the Low Countries. By December 1945 it was estimated by French authorities that 2,000 German prisoners were being killed or injured each month in accidents. In Norway the last available casualty record, from 29 August 1945, shows that by that time a total of 275 German soldiers died while clearing mines, while 392 had been injured. Death rates for the German civilians doing forced labor in the Soviet Union ranged between 19% and 39%, depending on category.

In the first half of the 19th century, small-scale slave raids took place across Polynesia to supply labor and sex workers for the whaling and sealing trades, with examples from both the westerly and easterly extremes of the Polynesian triangle. By the 1860s this had grown to a larger scale operation with Peruvian slave raids in the South Sea Islands to collect labor for the guano industry.

Ancient Hawaii was a caste society. People were born into specific social classes. Kauwa were those of the outcast or slave class. They are believed to have been war captives, or the descendants of war captives. Marriage between higher castes and the kauwa was strictly forbidden. The kauwa worked for the chiefs and were often used as human sacrifices at the luakini heiau. (They were not the only sacrifices; law-breakers of all castes or defeated political opponents were also acceptable as victims.)

The kapu system was abolished during the ʻAi Noa in 1819, and with it the distinction between the kauwā slave class and the makaʻāinana (commoners). The 1852 Constitution of the Kingdom of Hawaii officially made slavery illegal.

Before the arrival of European settlers, each Maori tribe () considered itself a separate entity equivalent to a nation. In traditional Maori society of Aotearoa, prisoners of war became taurekareka, slaves, unless released, ransomed or eaten. With some exceptions, the child of a slave remained a slave.

As far as it is possible to tell, slavery seems to have increased in the early 19th century with increased numbers of prisoners being taken by Māori military leaders, such as Hongi Hika and Te Rauparaha to satisfy the need for labor in the Musket Wars, to supply whalers and traders with food, flax and timber in return for western goods. The intertribal Musket Wars lasted 1807 to 1843 when large numbers of slaves were captured by northern tribes who had acquired muskets. About 20,000 Maori died in the wars which were concentrated in the North Island. An unknown number of slaves were captured. Northern tribes used slaves (called mokai) to grow large areas of potatoes for trade with visiting ships. Chiefs started an extensive sex trade in the Bay of Islands in the 1830s using mainly slave girls. By 1835 about 70-80 ships per year called into the port. One French captain described the impossibility of getting rid of the girls who swarmed over his ship outnumbering his crew of 70 by 3 to 1. All payments to the girls were stolen by the chief. By 1833 Christianity had become established in the north and large numbers of slaves were freed. However two Taranaki tribes, Ngati Tama and Ngati Mutunga, displaced by the wars carried out a carefully planned invasion of the Chatham Islands, 800 km east of Christchurch, in 1835. About 15% of the Polynesian Moriori natives who had migrated to the islands at about 1500 CE were killed, with many women being tortured to death. The remaining population was enslaved for the purpose of growing food, especially potatoes. The Moriori were treated in an inhumane and degrading manner for many years. Their culture was banned and they were forbidden to marry. Slavery was outlawed when the British entered into a constitutional arrangement with New Zealand in 1840 via the Treaty of Waitangi, although it did not end completely until government was effectively extended over the whole of the country with the defeat of the Kingi movement in the Wars of the mid-1860s.

Some Maori took Moriori partners. The state of enslavement of Moriori lasted until the 1860s although it had been discouraged by CMS missionaries in North New Zealand from the late 1820s. In 1870 Ngati Mutunga, one of the invading tribes, argued before the Native Land Court in New Zealand that their gross mistreatment of the Moriori was standard Maori practice or tikanga.

One group of Polynesians who migrated to the Chatham Islands became the Moriori who developed a largely pacifist culture. It was originally speculated that they settled the Chathams direct from Polynesia, but it is now widely believed they were disaffected Maori who emigrated from the South Island of New Zealand. Their pacifism left the Moriori unable to defend themselves when the islands were invaded by mainland Māori in the 1830s. Two Taranaki tribes, Ngati Tama and Ngati Mutunga, displaced by the musket wars, carried out a carefully planned invasion of the Chatham Islands, 800 km east of Christchurch, in 1835. About 15% of the Polynesian Moriori natives who had migrated to the islands at about 1500 CE were killed, with many women being tortured to death. The remaining population was enslaved for the purpose of growing food, especially potatoes. The Moriori were treated in an inhumane and degrading manner for many years. Their culture was banned and they were forbidden to marry. Slavery was outlawed when the British annexed New Zealand in 1840, immediately prior to the signing of the Treaty of Waitangi, although it did not end completely until government was effectively extended over the whole of the country with the defeat of the Kingi movement in the Wars of the mid-1860s.

Some 300 Moriori men, women and children were massacred and the remaining 1,200 to 1,300 survivors were enslaved.

Rapa Nui / Easter Island

The isolated island of Rapa Nui/ Easter Island was inhabited by the Rapanui, who suffered a series of slave raids from 1805 or earlier, culminating in a near genocidal experience in the 1860s. The 1805 raid was by American sealers and was one of a series that changed the attitude of the islanders to outside visitors, with reports in the 1820s and 1830s that all visitors received a hostile reception. In December 1862, Peruvian slave raiders took between 1,400 and 2,000 islanders back to Peru to work in the guano industry; this was about a third of the island's population and included much of the island's leadership, the last ariki-mau and possibly the last who could read Rongorongo. After intervention by the French ambassador in Lima, the last 15 survivors were returned to the island, but brought with them smallpox, which further devastated the island.

Slavery has existed, in one form or another, throughout the whole of human history. So, too, have movements to free large or distinct groups of slaves. However, abolitionism should be distinguished from efforts to help a particular group of slaves, or to restrict one practice, such as the slave trade.

Although there were numerous slave revolts in the Caribbean, the only successful uprising came in the French colony of Haiti in the 1790s, where the slaves rose up, killed the mulattoes and whites, and established the independent Republic of Haiti. Europe recoiled in horror.

Cyrus the Great, the founder of Persian Empire prohibited the systematic enslavement of conquered non-combatant population. Cyrus also freed slaves and allowed all deported peoples who were enslaved by preceding Assyrian and Babylonian kings, to return home. It is said that he freed up to 40,000 Jews and allowed them to return home. Cylinder of Cyrus the Great containing the Decree on the conquered non-combatant population.

In 1772, the Somersett Case (R. v. Knowles, ex parte Somersett) of the English Court of King's Bench ruled that it was unlawful for a slave to be forcibly taken abroad. The case has since been misrepresented as finding that slavery was unlawful in England (although not elsewhere in the British Empire). A similar case, that of Joseph Knight, took place in Scotland five years later and ruled slavery to be contrary to the law of Scotland.

Following the work of campaigners in the United Kingdom, such as William Wilberforce and Thomas Clarkson, the Act for the Abolition of the Slave Trade was passed by Parliament on 25 March 1807, coming into effect the following year. The act imposed a fine of £100 for every slave found aboard a British ship. The intention was to outlaw entirely the Atlantic slave trade within the whole British Empire.

The significance of the abolition of the British slave trade lay in the number of people hitherto sold and carried by British slave vessels. Britain shipped 2,532,300 Africans across the Atlantic, equalling 41% of the total transport of 6,132,900 individuals. This made the British empire the biggest slave-trade contributor in the world due to the magnitude of the empire, which made the abolition act all the more damaging to the global trade of slaves. Britain used its diplomatic influence to press other nations into treaties to ban their slave trade and to give the Royal Navy the right to interdict slave ships sailing under their national flag.

The Slavery Abolition Act, passed on 1 August 1833, outlawed slavery itself throughout the British Empire, with the exception of India. On 1 August 1834 slaves became indentured to their former owners in an apprenticeship system for six years. Full emancipation was granted ahead of schedule on 1 August 1838. Britain abolished slavery in both Hindu and Muslim India with the Indian Slavery Act, 1843.

Domestic slavery practised by the educated African coastal elites (as well as interior traditional rulers) in Sierra Leone was abolished in 1928. A study found practices of domestic slavery still widespread in rural areas in the 1970s.

There were slaves in mainland France (especially in trade ports such as Nantes or Bordeaux)., but the institution was never officially authorized there. The legal case of Jean Boucaux in 1739 clarified the unclear legal position of possible slaves in France, and was followed by laws that established registers for slaves in mainland France, who were limited to a three-year stay, for visits or learning a trade. Unregistered "slaves" in France were regarded as free. However, slavery was of vital importance in France's Caribbean possessions, especially Saint-Domingue.

In 1793, influenced by the French Declaration of the Rights of Man of August 1789 and alarmed as the massive slave revolt of August 1791 that had become the Haitian Revolution threatened to ally itself with the British, the French Revolutionary commissioners Sonthonax and Polverel declared general emancipation to reconcile them with France. In Paris, on 4 February 1794, Abbé Grégoire and the Convention ratified this action by officially abolishing slavery in all French territories outside mainland France, freeing all the slaves both for moral and security reasons.

Napoleon came to power in 1799 and soon had grandiose plans for the French sugar colonies; to achieve them he reintroduced slavery. Napoleon's major adventure into the Caribbean-sending 30,000 troops in 1802 to retake Saint Domingue (Haiti) from ex-slaves under Toussaint L'Ouverture who had revolted. Napoleon wanted to preserve France's financial benefits from the colony's sugar and coffee crops; he then planned to establish a major base at New Orleans. He therefore re-established slavery in Haiti and Guadeloupe, where it had been abolished after rebellions. Slaves and black freedmen fought the French for their freedom and independence. Revolutionary ideals played a central role in the fighting for it was the slaves and their allies who were fighting for the revolutionary ideals of freedom and equality, while the French troops under General Charles Leclerc fought to restore the order of the ancien régime. The goal of re-establishing slavery explicitly contradicted the ideals of the French Revolution. The French soldiers were unable to cope with the tropical diseases, and most died of yellow fever. Slavery was reimposed in Guadeloupe but not in Haiti, which became an independent black republic. Napoleon's vast colonial dreams for Egypt, India, the Caribbean, Louisiana, and even Australia were all doomed for lack of a fleet capable of matching Britain's Royal Navy. Realizing the fiasco Napoleon liquidated the Haiti project, brought home the survivors and sold off the huge Louisiana territory to the US in 1803.

In 1794 slavery was abolished in the French Empire. After seizing Lower Egypt in 1798, Napoleon Bonaparte issued a proclamation in Arabic, declaring all men to be free and equal. However, the French bought males as soldiers and females as concubines. Napoleon personally opposed the abolition and restored colonial slavery in 1802, a year after the capitulation of his troops in Egypt.

Victor Schœlcher and the 1848 abolition

The American Colonization Society, the primary vehicle for returning black Americans to greater freedom in Africa, established the colony of Liberia in 1821-23, on the premise that former American slaves would have greater freedom and equality there. The ACS assisted in the movement of thousands of African Americans to Liberia, with its founder Henry Clay stating; "unconquerable prejudice resulting from their color, they never could amalgamate with the free whites of this country. It was desirable, therefore, as it respected them, and the residue of the population of the country, to drain them off". Abraham Lincoln, an enthusiastic supporter of Clay, adopted his position on returning the blacks to their own land.

Slaves in the United States who escaped ownership would often make their way to Canada via the " Underground Railroad". The more famous of the African American abolitionists include former slaves Harriet Tubman, Sojourner Truth and Frederick Douglass. Many more people who opposed slavery and worked for abolition were northern whites, such as William Lloyd Garrison and John Brown. Slavery was legally abolished in 1865 by the Thirteenth Amendment to the United States Constitution.

While abolitionists agreed on the evils of slavery, there were differing opinions on what should happen after African Americans were freed. By the time of Emancipation, African-Americans were now native to the United States and did not want to leave. Most believed that their labor had made the land theirs as well as that of the whites.

The Declaration of the Powers, on the Abolition of the Slave Trade, of 8 February 1815 (Which also formed ACT, No. XV. of the Final Act of the Congress of Vienna of the same year) included in its first sentence the concept of the "principles of humanity and universal morality" as justification for ending a trade that was "odious in its continuance".

The 1926 Slavery Convention, an initiative of the League of Nations, was a turning point in banning global slavery. Article 4 of the Universal Declaration of Human Rights, adopted in 1948 by the UN General Assembly, explicitly banned slavery. The United Nations 1956 Supplementary Convention on the Abolition of Slavery was convened to outlaw and ban slavery worldwide, including child slavery. In December 1966, the UN General Assembly adopted the International Covenant on Civil and Political Rights, which was developed from the Universal Declaration of Human Rights. Article 4 of this international treaty bans slavery. The treaty came into force in March 1976 after it had been ratified by 35 nations.

As of November 2003, 104 nations had ratified the treaty. However, illegal forced labour involves millions of people in the 21st century, 43% for sexual exploitation and 32% for economic exploitation.

In May 2004, the 22 members of the Arab League adopted the Arab Charter on Human Rights, which incorporated the 1990 Cairo Declaration on Human Rights in Islam, which states:

Human beings are born free, and no one has the right to enslave, humiliate, oppress or exploit them, and there can be no subjugation but to God the Most-High.

-  Article 11, Cairo Declaration on Human Rights in Islam, 1990

Currently, the Anti-trafficking Coordination Team Initiative (ACT Team Initiative), a coordinated effort between the U.S. departments of justice, homeland security and labor, addresses human trafficking. The International Labour Organization estimates that there are 20.9 million victims of human trafficking globally, including 5.5 million children, of which 55% are women and girls.

The history of slavery originally was the history of the government's laws and policies toward slavery, and the political debates about it. Black history was promoted very largely at black colleges. The situation changed dramatically with the coming of the Civil Rights Movement of the 1950s. Attention shifted to the enslaved humans, the free blacks, and the struggles of the black community against adversity.

Peter Kolchin described the state of historiography in the early 20th century as follows:

During the first half of the twentieth century, a major component of this approach was often simply racism, manifest in the belief that blacks were, at best, imitative of whites. Thus Ulrich B. Phillips, the era's most celebrated and influential expert on slavery, combined a sophisticated portrait of the white planters' life and behavior with crude passing generalizations about the life and behavior of their black slaves.

Historians James Oliver Horton and Lois E. Horton described Phillips' mindset, methodology and influence:

His portrayal of blacks as passive, inferior people, whose African origins made them uncivilized, seemed to provide historical evidence for the theories of racial inferiority that supported racial segregation. Drawing evidence exclusively from plantation records, letters, southern newspapers, and other sources reflecting the slaveholder's point of view, Phillips depicted slave masters who provided for the welfare of their slaves and contended that true affection existed between master and slave.

Their account of the era rested, as one member of the Dunning school put it, on the assumption of "negro incapacity." Finding it impossible to believe that blacks could ever be independent actors on the stage of history, with their own aspirations and motivations, Dunning et al. portrayed African Americans either as "children", ignorant dupes manipulated by unscrupulous whites, or as savages, their primal passions unleashed by the end of slavery.

In the portrayal of the slave as a victim, the historian Stanley M. Elkins in his 1959 work Slavery: A Problem in American Institutional and Intellectual Life compared the effects of United States slavery to that resulting from the brutality of the Nazi concentration camps. He stated the institution destroyed the will of the slave, creating an "emasculated, docile Sambo" who identified totally with the owner. Elkins' thesis was challenged by historians. Gradually historians recognized that in addition to the effects of the owner-slave relationship, slaves did not live in a "totally closed environment but rather in one that permitted the emergence of enormous variety and allowed slaves to pursue important relationships with persons other than their master, including those to be found in their families, churches and communities."

Economic historians Robert W. Fogel and Stanley L. Engerman in the 1970s, through their work Time on the Cross, portrayed slaves as having internalized the Protestant work ethic of their owners. In portraying the more benign version of slavery, they also argue in their 1974 book that the material conditions under which the slaves lived and worked compared favorably to those of free workers in the agriculture and industry of the time. (This was also an argument of Southerners during the 19th century.)

In the 1970s and 1980s, historians made use of sources such as black music and statistical census data to create a more detailed and nuanced picture of slave life. Relying also on 19th-century autobiographies of ex-slaves (known as slave narratives) and the WPA Slave Narrative Collection, a set of interviews conducted with former slaves in the 1930s by the Federal Writers' Project, historians described slavery as the slaves remembered it. Far from slaves' being strictly victims or content, historians showed slaves as both resilient and autonomous in many of their activities. Despite their exercise of autonomy and their efforts to make a life within slavery, current historians recognize the precariousness of the slave's situation. Slave children quickly learned that they were subject to the direction of both their parents and their owners. They saw their parents disciplined just as they came to realize that they also could be physically or verbally abused by their owners. Historians writing during this era include John Blassingame ( Slave Community), Eugene Genovese ( Roll, Jordan, Roll), Leslie Howard Owens ( This Species of Property), and Herbert Gutman ( The Black Family in Slavery and Freedom).

Important work on slavery has continued; for instance, in 2003 Steven Hahn published the Pulitzer Prize-winning account, A Nation under Our Feet: Black Political Struggles in the Rural South from Slavery to the Great Migration, which examined how slaves built community and political understanding while enslaved, so they quickly began to form new associations and institutions when emancipated, including black churches separate from white control. In 2010, Robert E. Wright published a model that explains why slavery was more prevalent in some areas than others (e.g. southern than northern Delaware) and why some firms (individuals, corporations, plantation owners) chose slave labor while others used wage, indentured, or family labor instead.

Historical revisionism arrived when West Indian historian Eric Williams, a Marxist, in Capitalism and Slavery (1944), rejected this moral explanation and argued that abolition was now more profitable, for a century of sugarcane raising had exhausted the soil of the islands, and the plantations had become unprofitable. It was more profitable to sell the slaves to the government than to keep up operations. The 1807 prohibition of the international trade, Williams argued, prevented French expansion on other islands. Meanwhile, British investors turned to Asia, where labor was so plentiful that slavery was unnecessary. Williams went on to argue that slavery played a major role in making Britain prosperous. The high profits from the slave trade, he said, helped finance the Industrial Revolution. Britain enjoyed prosperity because of the capital gained from the unpaid work of slaves.

Since the 1970s numerous historians have challenged Williams from various angles and Gad Heuman has concluded, "More recent research has rejected this conclusion; it is now clear that the colonies of the British Caribbean profited considerably during the Revolutionary and Napoleonic Wars." In his major attack on the Williams's thesis, Seymour Drescher argues that Britain's abolition of the slave trade in 1807 resulted not from the diminishing value of slavery for Britain but instead from the moral outrage of the British voting public. Critics have also argued that slavery remained profitable in the 1830s because of innovations in agriculture so the profit motive was not central to abolition. Richardson (1998) finds Williams's claims regarding the Industrial Revolution are exaggerated, for profits from the slave trade amounted to less than 1% of domestic investment in Britain. Richardson further challenges claims (by African scholars) that the slave trade caused widespread depopulation and economic distress in Africa-indeed that it caused the "underdevelopment" of Africa. Admitting the horrible suffering of slaves, he notes that many Africans benefited directly because the first stage of the trade was always firmly in the hands of Africans. European slave ships waited at ports to purchase cargoes of people who were captured in the hinterland by African dealers and tribal leaders. Richardson finds that the "terms of trade" (how much the ship owners paid for the slave cargo) moved heavily in favor of the Africans after about 1750. That is, indigenous elites inside West and Central Africa made large and growing profits from slavery, thus increasing their wealth and power.

Economic historian Stanley Engerman finds that even without subtracting the associated costs of the slave trade (e.g., shipping costs, slave mortality, mortality of British people in Africa, defense costs) or reinvestment of profits back into the slave trade, the total profits from the slave trade and of West Indian plantations amounted to less than 5% of the British economy during any year of the Industrial Revolution. Engerman's 5% figure gives as much as possible in terms of benefit of the doubt to the Williams argument, not solely because it does not take into account the associated costs of the slave trade to Britain, but also because it carries the full-employment assumption from economics and holds the gross value of slave trade profits as a direct contribution to Britain's national income. Historian Richard Pares, in an article written before Williams's book, dismisses the influence of wealth generated from the West Indian plantations upon the financing of the Industrial Revolution, stating that whatever substantial flow of investment from West Indian profits into industry there was occurred after emancipation, not before.

The history of slavery spans many cultures, nationalities, and religions from ancient times to the present day. However the social, economic, and legal positions of slaves have differed vastly in different systems of slavery in different times and places. Slavery occurs relatively rarely among hunter-gatherer populations because it develops under conditions of social stratification.

Slavery in the colonial history of the United States, from 1600 to 1776, developed from complex factors, and researchers have proposed several theories to explain the development of the institution of slavery and of the slave trade. Slavery strongly correlated with Europe's American colonies' need for labor, especially for the labor-intensive plantation economies of the sugar colonies in the Caribbean, operated by Great Britain, France, Spain, and the Dutch Republic.

Most enslaved people who were ultimately brought to the Thirteen British colonies - the Eastern seaboard of what later became the United States - were imported from the Caribbean, not directly from Africa. They were taken to the Caribbean islands as a result of the Atlantic slave trade. Indigenous people were also enslaved in the North American colonies, but on a smaller scale, and Indian slavery largely ended in the late eighteenth century although the enslavement of Indigenous people did continue to occur in the Southern states until the Emancipation Proclamation issued by President Abraham Lincoln in 1863. In the English colonies, slave status for Africans became hereditary in the mid-17th century with the passage of colonial laws that defined children born in the colonies as taking the status of the mother, under the principle of partus sequitur ventrem.

Native Americans enslaved members of their own and other tribes before and after Europeans arrived, continuing into the 1800s; enslaved people might or might not be adopted eventually, especially if enslaved as children; and the enslavement might or might not be hereditary. Enslaved people included captives from wars and slave raids; captives bartered from other tribes, sometimes at great distances; children sold by their parents during famines; and men and women who staked themselves in gambling when they had nothing else, which put them into servitude in some cases for life.

Native Americans also captured and enslaved some early European explorers and colonists, and were enslaved themselves by the colonists, starting with the Spanish in the 1500s. Native Americans were enslaved by Spanish in Florida under the encomienda system. New England and the Carolinas captured Native Americans in wars and distributed them as slaves.

Larger societies structured as chiefdoms kept slaves as unpaid field laborers, while in band societies the ownership of enslaved captives attested to their captor's military prowess. Some war captives were also subjected to ritualized torture and execution. Alan Gallay and other historians emphasize differences between Native American enslavement of war captives and the European slave trading system, into which numerous native peoples were integrated.

Richard White, in The Middle Ground elucidates the complex social relationships between Native American groups and the early empires, including 'slave' culture and scalping. Robbie Ethridge states,

"Let there be no doubt...that the commercial trade in Indian slaves was not a continuation and adaptation of pre-existing captivity patterns. It was a new kind of slave, requiring a new kind of occupational specialty...organized militaristic slavers."

One example of this militaristic slaving can be seen in Nathaniel Bacon's actions in Virginia during the late 1670s. In June 1676, the Virginia assembly granted Bacon and his men what equated to a slave-hunting license by providing that any enemy Native Americans caught were to be slaves for life. They also provided soldiers who had captured Native Americans with the right to "retain and keep all such Native American slaves or other Native American goods as they either have taken or hereafter shall take." By this order, the assembly had made a public decision to enslave Native Americans. In the years to follow, other laws resulted in Native Americans being grouped with other non-Christian servants who had imported to the colonies (Negro slaves) as slaves for life.

Puritan New England, Virginia, Spanish Florida, and the Carolina colonies engaged in large-scale[citation needed ] enslavement of Native Americans, often through the use of Indian proxies to wage war and acquire the slaves. In New England, slave raiding accompanied the Pequot War and King Philip's War but declined after the latter war ended in 1676. Enslaved Native Americans were in Jamestown from the early years of the settlement,[citation needed ] but large-scale cooperation between English slavers and the West and Occaneechi peoples, whom they armed with guns, did not begin until the 1640s. These groups conducted enslaving raids in what is now Georgia, Tennessee, North Carolina, South Carolina, Florida, and possibly Alabama. The Carolina slave trade, which included both trading and direct raids by colonists, was the largest among the British colonies in North America, estimated at 24,000 to 51,000 Native Americans by Gallay.

Historian Ulrich Phillips argues that Africans were inculcated as slaves and the best answer to the labor shortage in the New World because Native American slaves were more familiar with the environment, and would often successfully escape into the wilderness that African slaves had much more difficulty surviving in. Also, early colonial America depended heavily on the sugar trade, which led to malaria, a disease the Africans were far less susceptible to than Native American slaves.

The first African slaves in what would become the present day United States of America arrived in 1526 with Lucas Vázquez de Ayllón's establishment of San Miguel de Gualdape on the current Georgia or Carolina coast. They rebelled and lived with indigenous people, destroying the colony in less than 2 months.

Georgia was the last of the Thirteen Colonies to be established and the furthest south (Florida was not one of the Thirteen Colonies). Founded in the 1730s, Georgia's powerful backers did not object to slavery as an institution, but their business model was to rely on labor from Britain (primarily England's poor) and they were also concerned with security, given the closeness of then Spanish Florida, and Spain's regular offers to enemy-slaves to revolt or escape. Despite agitation for slavery, it was not until a defeat of the Spanish by Georgia colonials in the 1740s that arguments for opening the colony to slavery intensified. To staff the rice plantations and settlements, Georgia's proprietors relented in 1751, and African slavery grew quickly. After becoming a royal colony, in the 1760s Georgia began importing slaves directly from Africa.

When St. Augustine, FL, was founded in 1565, the site already had enslaved Native Americans, whose ancestors had migrated from Cuba. The Spanish introduced African slaves in what is now Florida soon after they claimed the area in 1513. The Spanish settlement was sparse and they held comparatively few slaves. African slaves arrived in Florida in 1539 with Hernando de Soto, and in the 1565 founding of St. Augustine, Florida.

The Spanish promised freedom to refugee slaves from the English colonies of South Carolina and Georgia in order to destabilize English settlement. If the slaves converted to Catholicism and agreed to serve in a militia for Spain, they could become Spanish citizens. By 1730 the black settlement known as Fort Mose developed near St. Augustine and was later fortified. There were two known Fort Mose sites in the eighteenth century, and the men helped defend St. Augustine against the British. It is "the only known free black town in the present-day southern United States that a European colonial government-sponsored. The Fort Mose Site, today a National Historic Landmark, is the location of the second Fort Mose." During the nineteenth century, this site became marsh and wetlands.

In 1763, Great Britain took over Florida in an exchange with Spain after defeating France in the Seven Years' War. Spain evacuated its citizens from St. Augustine, including the residents of Fort Mose, transporting them to Cuba. As Britain developed the colony for plantation agriculture, the percentage of slaves in the population in twenty years rose from 18% to almost 65% by 1783.

The first recorded Africans in Virginia arrived in late August 1619. The , a privateer ship owned by Robert Rich, 2nd Earl of Warwick but flying a Dutch flag, docked at what is now Old Point Comfort (located in modern-day Hampton) with approximately 20 Africans. They were captives from the area of present-day Angola and had been seized by the British crew from a Portuguese slave ship, the "São João Bautista". To obtain the Africans, the Jamestown colony traded provisions with the ship. These individuals appear to have been treated as indentured servants, since slave laws were not passed until later, in 1641 in Massachusetts and in 1661 in Virginia.

Some number of the colony's early Africans earned freedom by fulfilling a work contract or for converting to Christianity. At least one of these, Anthony Johnson, in turn, acquired slaves or indentured servants for workers himself. Historians such as Edmund Morgan say this evidence suggests that racial attitudes were much more flexible in early 17th-century Virginia than they would later become. A 1625 census recorded 23 Africans in Virginia. In 1649 there were 300, and in 1690 there were 950. Over this period, legal distinctions between white indentured servants and "Negros" widened into lifelong and inheritable chattel-slavery for Africans.

Until the early 18th century, enslaved Africans were difficult to acquire in the colonies that became the United States, as most were sold to the West Indies, where the large plantations and high mortality rates required continued importation of slaves. One of the first major centers of African slavery in the English North American colonies occurred with the founding of Charles Town and the Province of Carolina in 1670. The colony was founded mainly by planters from the overpopulated English sugar island of Barbados, who brought relatively large numbers of African slaves from that island to establish new plantations.

To meet agricultural labor needs, colonists also practiced Indian slavery for some time. The Carolinians transformed the Indian slave trade during the late 17th and early 18th centuries by treating such slaves as a trade commodity to be exported, mainly to the West Indies. Historian Alan Gallay estimates that between 1670 and 1715, between 24,000 and 51,000 captive Native Americans were exported from South Carolina-much more than the number of Africans imported to the colonies of the future United States during the same period.

Slaves, African and Native American, made up a smaller part of the New England economy, which was based on yeoman farming and trades, and a smaller fraction of the population, but they were present. The Puritans codified slavery in 1641. The Massachusetts royal colony passed the Body of Liberties, which prohibited slavery in some instances, but did allow three legal bases of slavery. Slaves could be held if they were captives of war if they sold themselves into slavery, were purchased from elsewhere, or if they were sentenced to slavery by the governing authority. The Body of Liberties used the word "strangers" to refer to people bought and sold as slaves, as they were generally not English subjects. Colonists came to equate this term with Native Americans and Africans.

The Dutch West India Company introduced slavery in 1625 with the importation of eleven enslaved blacks who worked as farmers, fur traders, and builders to New Amsterdam (present day New York City), capital of the nascent province of New Netherland. The Dutch colony expanded across the North River (Hudson River) to Bergen (in today's New Jersey). Later, slaves were also held privately by settlers in the area. Although enslaved, the Africans had a few basic rights and families were usually kept intact. They were admitted to the Dutch Reformed Church and married by its ministers, and their children could be baptized. Slaves could testify in court, sign legal documents, and bring civil actions against whites. Some were permitted to work after hours earning wages equal to those paid to white workers. When the colony fell to the English in the 1660s, the company freed all its slaves, which created an early nucleus of free Negros in the area.

The English continued to import more slaves. Enslaved Africans performed a wide variety of skilled and unskilled jobs, mostly in the burgeoning port city and surrounding agricultural areas. In 1703 more than 42% of New York City's households held slaves, a percentage higher than in the cities of Boston and Philadelphia, and second only to Charleston in the South.

Midwest, Mississippi River, and Louisiana

The French introduced legalized slavery into their colonies in New France both near the Great Lakes and the Mississippi River. (They also used slave labor on their island colonies in the Caribbean: Guadeloupe and especially Saint-Domingue.) After the port of New Orleans was founded in 1718 with access to the Gulf Coast, French colonists imported more African slaves to the Illinois Country for use as agricultural or mining laborers. By the mid-eighteenth century, slaves accounted for as many as a third of the limited population in that rural area.

Slavery was much more extensive in colonial Louisiana, where the French developed sugar cane plantations along the Mississippi River. Slavery was maintained during the French (1699 - 1763, and 1800 - 1803) and Spanish (1763 - 1800) periods of government. The first people enslaved by the French were Native Americans, but they could easily escape into the countryside which they knew well. Beginning in the early 18th century, the French imported Africans as laborers in their efforts to develop the colony. Mortality rates were high for both colonists and Africans, and new workers had to be imported.

Implemented in colonial Louisiana in 1724, Louis XIV of France's regulated the slave trade and the institution of slavery in the French colonies. As a result, Louisiana and the Mobile area developed very different patterns of slavery compared to the British colonies. As written, the Code Noir gave some rights to slaves, including the right to marry. Although it authorized and codified cruel corporal punishment against slaves under certain conditions, it forbade slave owners to torture slaves, to separate married couples (and to separate young children from their mothers). It required owners to instruct slaves in the Catholic faith, implying that Africans were human beings endowed with a soul, an idea that had not been acknowledged until then.

The Code Noir forbade interracial marriages, but interracial relationships were formed in La Louisiane from the earliest years. In New Orleans society particularly, a formal system of concubinage, known as , developed. Usually formed between young white men and African or African-American women, these relationships were formalized with contracts that sometimes provided for freedom for a woman and her children (if she was still enslaved), education for the mixed-race children of the union, and sometimes a property settlement. The free people of color became an intermediate social caste between the whites and the mass of enslaved blacks; many practiced artisan trades, and some acquired educations and property.

Gradually in the English colonies, slavery became known as a racial caste that generally encompassed all people of African descent, even if mixed race. From the 17th century, Virginia defined all children born to enslaved mothers as born into slavery, regardless of their father's ancestry. Similarly, Virginia denied that converting a slave to Christianity was grounds for freedom. Even free people of color or mixed-race (known as mulattoes) were restricted in their rights, especially as colonies passed harsher laws after early slave revolts. During the centuries of slavery in the British colonies, many slaves were of mixed-race ancestry.

Colonial slave rebellions before 1776, or before 1801 for Louisiana, include:

While the British knew about Spanish and Portuguese slave trading, they did not implement slave labor in the Americas until the 17th century. British travelers were fascinated by the dark-skinned people they found in West Africa; they developed mythologies that situated them in their view of the cosmos.

The first Africans to arrive in England came voluntarily in 1555 with John Lok (an ancestor of the famous philosopher John Locke). Lok intended to teach them English in order to facilitate the trading of material goods with West Africa. This model gave way to a slave trade initiated by John Hawkins, who captured 300 Africans and sold them to the Spanish. Blacks in England were subordinate but never had the legal status of chattel slaves.

In 1607, England established Jamestown as its first permanent colony on the North American continent. Tobacco became the chief commodity crop of the colony, due to the efforts of John Rolfe in 1611. Once it became clear that tobacco was going to drive the Jamestown economy, more workers were needed for the labor-intensive crop. The British aristocracy also needed to find a labor force to work on its sugar plantations in the Americas. The major sources were indentured servants from Britain, Native Americans, and West Africans. During this period, Barbados became an English Colony in 1624 and the Caribbean's Jamaica in 1655. These and other Caribbean colonies became the center of wealth generated from sugar cane and the focus of the slave trade for the growing English empire.

The English entertained two lines of thought simultaneously toward the indigenous Native Americans. Because these people were lighter-skinned, they were seen as more European and therefore as candidates for civilization. At the same time, because they were occupying the land desired by the colonial powers, they were from the beginning, targets of potential military attack.

At first, indentured servants were used as the needed labor. These servants provided up to seven years of service in exchange for having their trip to Jamestown paid for by someone in Jamestown. Once the seven years were over, the indentured servant was free to live in Jamestown as a regular citizen. However, colonists began to see indentured servants as too costly, in part because the high mortality rate meant the force had to be resupplied.

In 1619, Dutch traders brought African slaves taken from a Spanish ship to Point Comfort.

Several colonial colleges held enslaved people as workers and relied on them to operate.

The laws relating to slavery and their enforcement hardened in the second half of the 17th century, and the prospects for Africans and their descendants grew increasingly dim. By 1640, the Virginia courts had sentenced at least one black servant, John Punch, to slavery. In 1656 Elizabeth Key won a suit for freedom based on her father's status as a free Englishman, and his having baptized her as Christian in the Church of England. In 1662 the Virginia House of Burgesses passed a law with the doctrine of , stating that any child born in the colony would follow the status of its mother, bond or free. This was an overturn of a longheld principle of English Common Law, whereby a child's status followed that of the father. It enabled slaveholders and other white men to hide the mixed-race children born of their rape of slave women and removed their responsibility to acknowledge, support, or emancipate the children.

During the second half of the 17th century, the British economy improved and the supply of British indentured servants declined, as poor Britons had better economic opportunities at home. At the same time, Bacon's Rebellion of 1676 led planters to worry about the prospective dangers of creating a large class of restless, landless, and relatively poor white men (most of them former indentured servants). Wealthy Virginia and Maryland planters began to buy slaves in preference to indentured servants during the 1660s and 1670s, and poorer planters followed suit by c.1700. (Slaves cost more than servants, so initially only the wealthy could invest in slaves.) The first British colonists in Carolina introduced African slavery into the colony in 1670, the year the colony was founded, and Charleston ultimately became the busiest slave port in North America. Slavery spread from the South Carolina Lowcountry first to Georgia, then across the Deep South as Virginia's influence had crossed the Appalachians to Kentucky and Tennessee. Northerners also purchased slaves, though on a much smaller scale. Enslaved people outnumbered free whites in South Carolina from the early 1700s to the Civil War. An authoritarian political culture evolved to prevent slave rebellion and justify white slaveholding. Northern slaves typically dwelled in towns, rather than on plantations as in the South, and worked as artisans and artisans' assistants, sailors and longshoremen, and domestic servants.

In 1672, King Charles II rechartered the Royal African Company (it had initially been set up in 1660), as an English monopoly for the African slave and commodities trade-thereafter in 1698, by statute, the English parliament opened the trade to all English subjects. The slave trade to the mid-Atlantic colonies increased substantially in the 1680s, and by 1710 the African population in Virginia had increased to 23,100 (42% of total); Maryland contained 8,000 Africans (23% of total). In the early 18th century, England passed Spain and Portugal to become the world's leading slave-trader.

The North American royal colonies not only imported Africans but also captured Native Americans, impressing them into slavery. Many Native Americans were shipped as slaves to the Caribbean. Many of these slaves from the British colonies were able to escape by heading south, to the Spanish colony of Florida. There they were given their freedom if they declared their allegiance to the King of Spain and accepted the Catholic Church. In 1739 Fort Mose was established by African American freedmen and became the northern defense post for St. Augustine. In 1740, English forces attacked and destroyed the fort, which was rebuilt in 1752. Because Fort Mose became a haven for escaped slaves from the English colonies to the north, it is considered a precursor site of the Underground Railroad.

Chattel slavery developed in British North America before the full legal apparatus that supported slavery did. During the late 17th century and early 18th century, harsh new slave codes limited the rights of African slaves and cut off their avenues to freedom. The first full-scale slave code in British North America was South Carolina's (1696), which was modeled on the colonial Barbados slave code of 1661 and was updated and expanded regularly throughout the 18th century.

A 1691 Virginia law prohibited slaveholders from emancipating slaves unless they paid for the freedmen's transportation out of Virginia. Virginia criminalized interracial marriage in 1691, and subsequent laws abolished blacks' rights to vote, hold office, and bear arms. Virginia's House of Burgesses established the basic legal framework for slavery in 1705.

Of the enslaved Africans brought to the New World an estimated 5-7% ended up in British North America. The vast majority of slaves transported across the Atlantic Ocean were sent to the Caribbean sugar colonies, Brazil, or Spanish America. Throughout the Americas, but especially in the Caribbean, tropical disease took a large toll on their population and required large numbers of replacements. Many Africans had limited natural immunity to yellow fever and malaria; but malnutrition, poor housing, inadequate clothing allowances, and overwork contributed to a high mortality rate.

In British North America the slave population rapidly increased via the birth rate, whereas in the Caribbean colonies they did not. The lack of proper nourishment, being suppressed sexually, and poor health are possible reasons. Of the small numbers of babies born to slaves in the Caribbean, only about 1/4 survived the miserable conditions on sugar plantations.

It was not only the major colonial powers of Western Europe such as France, England, Spain, Portugal, and the Netherlands that were involved. Other countries, including Sweden and Denmark, participated in the trans- Atlantic slave trade though on a much more limited scale.

"Depending upon their age and gender, slaves were assigned a particular task, or tasks, that had to be completed during the course of the day." In certain settings, men would participate in the hard labor, such as working on the farm, while women would generally work in the household. They would "be sent out on errands but in most cases their jobs required that they spend much of their time within their owner's household." These gender distinctions were mainly applied in the Northern colonies and on larger plantations. In Southern colonies and smaller farms, however, women and men typically engaged in the same roles, both working in the tobacco crop fields for example.

Although slave women and men in some areas performed the same type of day-to-day work, "[t]he female slave...was faced with the prospect of being forced into sexual relationships for the purpose of reproduction." This reproduction would either be forced between one African slave and another, or between the slave woman and the owner. Slave owners saw slave women in terms of prospective fertility. That way, the number of slaves on a plantation could multiply without having to purchase another African. Unlike the patriarchal society of white Anglo-American colonists, "slave families" were more matriarchal in practice. "Masters believed that slave mothers, like white women, had a natural bond with their children that therefore it was their responsibility - more so than that of slave fathers - to care for their offspring." Therefore, women had the extra responsibility, on top of their other day-to-day work, to take care of children. Men, in turn, were often separated from their families. "At the same time that slaveholders promoted a strong bond between slave mothers and their children, they denied to slave fathers their paternal rights of ownership and authority..." Biological families were often separated by sale.

Some historians, notably Edmund Morgan, have suggested that indentured servitude provided a model for slavery in 17th-century Virginia. In practice, indentured servants were teenagers in England whose father sold their labor voluntarily for a period of time (typically four to seven years), in return for free passage to the colonies, room and board and clothes, and training in an occupation. After that, they received cash, clothing, tools, and/or land, and became ordinary settlers.

In 1688, four German Quakers in Germantown, a town outside Philadelphia, wrote a petition against the use of slaves by the English colonists in the nearby countryside. They presented the petition to their local Quaker Meeting, and the Meeting was sympathetic, but could not decide what the appropriate response should be. The Meeting passed the petition up the chain of authority to Philadelphia Yearly Meeting, where it continued to be ignored. It was archived and forgotten for 150 years.

The Quaker petition was the first public American document of its kind to protest slavery. It was also one of the first public declarations of universal human rights. While the petition was forgotten for a time, the idea that every human has equal rights were regularly discussed in Philadelphia Quaker society through the eighteenth century.

During the Great Awakening of the late eighteenth century, Methodist and Baptist preachers toured in the South, trying to persuade planters to manumit their slaves on the basis of equality in God's eyes. They also accepted slaves as members and preachers of new chapels and churches. The first black churches (all Baptist) in what became the United States were founded by slaves and free blacks in Aiken County, South Carolina in 1773, Petersburg, Virginia in 1774, and Savannah, Georgia in 1778, before the end of the Revolutionary War.

Slavery was officially sanctioned in 1776 by the Philadelphia Yearly Meeting.

In the early 21st century, new research has revealed that small numbers of East Indians were brought to the colonies as enslaved laborers, during the period when both India and the colonies were under British control. As an example, an ad in the Virginia Gazette of Aug. 4, 1768, describes one young "East Indian" as "a well made fellow, about 5 feet 4 inches high" who had "a thin visage, a very sly look, and a remarkable set of fine white teeth." Another slave is identified as "an East India negro man" who speaks French and English. Most of the Indian slaves were already converted to Christianity, were fluent in English, and took western names. Their original names and homes are not known. Their descendants have mostly merged with the African-American community, which also incorporated European ancestors. Today, descendants of such East Indian slaves may have a small percent of DNA from their Asiatic ancestors but it likely falls below the detectable levels for today's DNA tests.

African and African American slaves expressed their opposition to slavery through armed uprisings such as the Stono Rebellion (1739) in South Carolina. More typically, they resisted through work slowdowns, tool-breaking, and running away, either for short periods or permanently. Until the Revolutionary era, almost no white American colonists spoke out against slavery. Even the Quakers generally tolerated slaveholding (and slave-trading) until the mid-18th century, although they emerged as vocal opponents of slavery in the Revolutionary era.

During and following the Revolution, the northern states all abolished slavery, with New Jersey acting last in 1804. Some of these state jurisdictions enacted the first abolition laws in the entire New World. In states that passed gradual abolition laws, such as New York and New Jersey, children born to slave mothers had to serve an extended period of indenture into young adulthood. In other cases, some slaves were reclassified as indentured servants, effectively preserving the institution of slavery through another name.

Often citing Revolutionary ideals, some slaveholders freed their slaves in the first two decades after independence, either outright or through their wills. The proportion of free blacks rose markedly in the Upper South in this period, before the invention of the cotton gin created a new demand for slaves in the developing "Cotton Kingdom" of the Deep South.

By 1808 (the first year allowed by the Constitution to federally ban the import slave trade), all states (except South Carolina) had banned the international buying or selling of slaves. Acting on the advice of President Thomas Jefferson, who denounced the international trade as "violations of human rights which have been so long continued on the unoffending inhabitants of Africa, in which the morality, the reputation, and the best interests of our country have long been eager to proscribe", in 1807 Congress also banned the international slave trade. However, the domestic slave trade continued in the South. It brought great wealth to the South, especially to New Orleans, which became the fourth largest city in the country, also based on the growth of its port. In the antebellum years, more than one million enslaved African Americans were transported from the Upper South to the developing Deep South, mostly in the slave trade. Cotton culture, dependent on slavery, formed the basis of new wealth in the Deep South.

In 1844 the Quaker petition was rediscovered and became a focus of the burgeoning abolitionist movement.

On 1 January 1863, Abraham Lincoln signed Emancipation Proclamation freeing slaves in areas in rebellion during the American Civil War when Union troops advanced south. The Thirteenth Amendment (abolition of slavery and involuntary servitude) was ratified in December 1865.

Slavery in the colonial history of the United States, from 1600 to 1776, developed from complex factors, and researchers have proposed several theories to explain the development of the institution of slavery and of the slave trade. Slavery strongly correlated with Europe's American colonies' need for labor, especially for the labor-intensive plantation economies of the sugar colonies in the Caribbean, operated by Great Britain, France, Spain, and the Dutch Republic.

Most enslaved people who were ultimately brought to the Thirteen British colonies - the Eastern seaboard of what later became the United States - were imported from the Caribbean, not directly from Africa. They were taken to the Caribbean islands as a result of the Atlantic slave trade. Indigenous people were also enslaved in the North American colonies, but on a smaller scale, and Indian slavery largely ended in the late eighteenth century although the enslavement of Indigenous people did continue to occur in the Southern states until the Emancipation Proclamation issued by President Abraham Lincoln in 1863. In the English colonies, slave status for Africans became hereditary in the mid-17th century with the passage of colonial laws that defined children born in the colonies as taking the status of the mother, under the principle of partus sequitur ventrem.

Native Americans enslaved members of their own and other tribes before and after Europeans arrived, continuing into the 1800s; enslaved people might or might not be adopted eventually, especially if enslaved as children; and the enslavement might or might not be hereditary. Enslaved people included captives from wars and slave raids; captives bartered from other tribes, sometimes at great distances; children sold by their parents during famines; and men and women who staked themselves in gambling when they had nothing else, which put them into servitude in some cases for life.

Native Americans also captured and enslaved some early European explorers and colonists, and were enslaved themselves by the colonists, starting with the Spanish in the 1500s. Native Americans were enslaved by Spanish in Florida under the encomienda system. New England and the Carolinas captured Native Americans in wars and distributed them as slaves.

Larger societies structured as chiefdoms kept slaves as unpaid field laborers, while in band societies the ownership of enslaved captives attested to their captor's military prowess. Some war captives were also subjected to ritualized torture and execution. Alan Gallay and other historians emphasize differences between Native American enslavement of war captives and the European slave trading system, into which numerous native peoples were integrated.

Richard White, in The Middle Ground elucidates the complex social relationships between Native American groups and the early empires, including 'slave' culture and scalping. Robbie Ethridge states,

"Let there be no doubt...that the commercial trade in Indian slaves was not a continuation and adaptation of pre-existing captivity patterns. It was a new kind of slave, requiring a new kind of occupational specialty...organized militaristic slavers."

One example of this militaristic slaving can be seen in Nathaniel Bacon's actions in Virginia during the late 1670s. In June 1676, the Virginia assembly granted Bacon and his men what equated to a slave-hunting license by providing that any enemy Native Americans caught were to be slaves for life. They also provided soldiers who had captured Native Americans with the right to "retain and keep all such Native American slaves or other Native American goods as they either have taken or hereafter shall take." By this order, the assembly had made a public decision to enslave Native Americans. In the years to follow, other laws resulted in Native Americans being grouped with other non-Christian servants who had imported to the colonies (Negro slaves) as slaves for life.

Puritan New England, Virginia, Spanish Florida, and the Carolina colonies engaged in large-scale[citation needed ] enslavement of Native Americans, often through the use of Indian proxies to wage war and acquire the slaves. In New England, slave raiding accompanied the Pequot War and King Philip's War but declined after the latter war ended in 1676. Enslaved Native Americans were in Jamestown from the early years of the settlement,[citation needed ] but large-scale cooperation between English slavers and the West and Occaneechi peoples, whom they armed with guns, did not begin until the 1640s. These groups conducted enslaving raids in what is now Georgia, Tennessee, North Carolina, South Carolina, Florida, and possibly Alabama. The Carolina slave trade, which included both trading and direct raids by colonists, was the largest among the British colonies in North America, estimated at 24,000 to 51,000 Native Americans by Gallay.

Historian Ulrich Phillips argues that Africans were inculcated as slaves and the best answer to the labor shortage in the New World because Native American slaves were more familiar with the environment, and would often successfully escape into the wilderness that African slaves had much more difficulty surviving in. Also, early colonial America depended heavily on the sugar trade, which led to malaria, a disease the Africans were far less susceptible to than Native American slaves.

The first African slaves in what would become the present day United States of America arrived in 1526 with Lucas Vázquez de Ayllón's establishment of San Miguel de Gualdape on the current Georgia or Carolina coast. They rebelled and lived with indigenous people, destroying the colony in less than 2 months.

Georgia was the last of the Thirteen Colonies to be established and the furthest south (Florida was not one of the Thirteen Colonies). Founded in the 1730s, Georgia's powerful backers did not object to slavery as an institution, but their business model was to rely on labor from Britain (primarily England's poor) and they were also concerned with security, given the closeness of then Spanish Florida, and Spain's regular offers to enemy-slaves to revolt or escape. Despite agitation for slavery, it was not until a defeat of the Spanish by Georgia colonials in the 1740s that arguments for opening the colony to slavery intensified. To staff the rice plantations and settlements, Georgia's proprietors relented in 1751, and African slavery grew quickly. After becoming a royal colony, in the 1760s Georgia began importing slaves directly from Africa.

When St. Augustine, FL, was founded in 1565, the site already had enslaved Native Americans, whose ancestors had migrated from Cuba. The Spanish introduced African slaves in what is now Florida soon after they claimed the area in 1513. The Spanish settlement was sparse and they held comparatively few slaves. African slaves arrived in Florida in 1539 with Hernando de Soto, and in the 1565 founding of St. Augustine, Florida.

The Spanish promised freedom to refugee slaves from the English colonies of South Carolina and Georgia in order to destabilize English settlement. If the slaves converted to Catholicism and agreed to serve in a militia for Spain, they could become Spanish citizens. By 1730 the black settlement known as Fort Mose developed near St. Augustine and was later fortified. There were two known Fort Mose sites in the eighteenth century, and the men helped defend St. Augustine against the British. It is "the only known free black town in the present-day southern United States that a European colonial government-sponsored. The Fort Mose Site, today a National Historic Landmark, is the location of the second Fort Mose." During the nineteenth century, this site became marsh and wetlands.

In 1763, Great Britain took over Florida in an exchange with Spain after defeating France in the Seven Years' War. Spain evacuated its citizens from St. Augustine, including the residents of Fort Mose, transporting them to Cuba. As Britain developed the colony for plantation agriculture, the percentage of slaves in the population in twenty years rose from 18% to almost 65% by 1783.

The first recorded Africans in Virginia arrived in late August 1619. The , a privateer ship owned by Robert Rich, 2nd Earl of Warwick but flying a Dutch flag, docked at what is now Old Point Comfort (located in modern-day Hampton) with approximately 20 Africans. They were captives from the area of present-day Angola and had been seized by the British crew from a Portuguese slave ship, the "São João Bautista". To obtain the Africans, the Jamestown colony traded provisions with the ship. These individuals appear to have been treated as indentured servants, since slave laws were not passed until later, in 1641 in Massachusetts and in 1661 in Virginia.

Some number of the colony's early Africans earned freedom by fulfilling a work contract or for converting to Christianity. At least one of these, Anthony Johnson, in turn, acquired slaves or indentured servants for workers himself. Historians such as Edmund Morgan say this evidence suggests that racial attitudes were much more flexible in early 17th-century Virginia than they would later become. A 1625 census recorded 23 Africans in Virginia. In 1649 there were 300, and in 1690 there were 950. Over this period, legal distinctions between white indentured servants and "Negros" widened into lifelong and inheritable chattel-slavery for Africans.

Until the early 18th century, enslaved Africans were difficult to acquire in the colonies that became the United States, as most were sold to the West Indies, where the large plantations and high mortality rates required continued importation of slaves. One of the first major centers of African slavery in the English North American colonies occurred with the founding of Charles Town and the Province of Carolina in 1670. The colony was founded mainly by planters from the overpopulated English sugar island of Barbados, who brought relatively large numbers of African slaves from that island to establish new plantations.

To meet agricultural labor needs, colonists also practiced Indian slavery for some time. The Carolinians transformed the Indian slave trade during the late 17th and early 18th centuries by treating such slaves as a trade commodity to be exported, mainly to the West Indies. Historian Alan Gallay estimates that between 1670 and 1715, between 24,000 and 51,000 captive Native Americans were exported from South Carolina-much more than the number of Africans imported to the colonies of the future United States during the same period.

Slaves, African and Native American, made up a smaller part of the New England economy, which was based on yeoman farming and trades, and a smaller fraction of the population, but they were present. The Puritans codified slavery in 1641. The Massachusetts royal colony passed the Body of Liberties, which prohibited slavery in some instances, but did allow three legal bases of slavery. Slaves could be held if they were captives of war if they sold themselves into slavery, were purchased from elsewhere, or if they were sentenced to slavery by the governing authority. The Body of Liberties used the word "strangers" to refer to people bought and sold as slaves, as they were generally not English subjects. Colonists came to equate this term with Native Americans and Africans.

The Dutch West India Company introduced slavery in 1625 with the importation of eleven enslaved blacks who worked as farmers, fur traders, and builders to New Amsterdam (present day New York City), capital of the nascent province of New Netherland. The Dutch colony expanded across the North River (Hudson River) to Bergen (in today's New Jersey). Later, slaves were also held privately by settlers in the area. Although enslaved, the Africans had a few basic rights and families were usually kept intact. They were admitted to the Dutch Reformed Church and married by its ministers, and their children could be baptized. Slaves could testify in court, sign legal documents, and bring civil actions against whites. Some were permitted to work after hours earning wages equal to those paid to white workers. When the colony fell to the English in the 1660s, the company freed all its slaves, which created an early nucleus of free Negros in the area.

The English continued to import more slaves. Enslaved Africans performed a wide variety of skilled and unskilled jobs, mostly in the burgeoning port city and surrounding agricultural areas. In 1703 more than 42% of New York City's households held slaves, a percentage higher than in the cities of Boston and Philadelphia, and second only to Charleston in the South.

Midwest, Mississippi River, and Louisiana

The French introduced legalized slavery into their colonies in New France both near the Great Lakes and the Mississippi River. (They also used slave labor on their island colonies in the Caribbean: Guadeloupe and especially Saint-Domingue.) After the port of New Orleans was founded in 1718 with access to the Gulf Coast, French colonists imported more African slaves to the Illinois Country for use as agricultural or mining laborers. By the mid-eighteenth century, slaves accounted for as many as a third of the limited population in that rural area.

Slavery was much more extensive in colonial Louisiana, where the French developed sugar cane plantations along the Mississippi River. Slavery was maintained during the French (1699 - 1763, and 1800 - 1803) and Spanish (1763 - 1800) periods of government. The first people enslaved by the French were Native Americans, but they could easily escape into the countryside which they knew well. Beginning in the early 18th century, the French imported Africans as laborers in their efforts to develop the colony. Mortality rates were high for both colonists and Africans, and new workers had to be imported.

Implemented in colonial Louisiana in 1724, Louis XIV of France's regulated the slave trade and the institution of slavery in the French colonies. As a result, Louisiana and the Mobile area developed very different patterns of slavery compared to the British colonies. As written, the Code Noir gave some rights to slaves, including the right to marry. Although it authorized and codified cruel corporal punishment against slaves under certain conditions, it forbade slave owners to torture slaves, to separate married couples (and to separate young children from their mothers). It required owners to instruct slaves in the Catholic faith, implying that Africans were human beings endowed with a soul, an idea that had not been acknowledged until then.

The Code Noir forbade interracial marriages, but interracial relationships were formed in La Louisiane from the earliest years. In New Orleans society particularly, a formal system of concubinage, known as , developed. Usually formed between young white men and African or African-American women, these relationships were formalized with contracts that sometimes provided for freedom for a woman and her children (if she was still enslaved), education for the mixed-race children of the union, and sometimes a property settlement. The free people of color became an intermediate social caste between the whites and the mass of enslaved blacks; many practiced artisan trades, and some acquired educations and property.

Gradually in the English colonies, slavery became known as a racial caste that generally encompassed all people of African descent, even if mixed race. From the 17th century, Virginia defined all children born to enslaved mothers as born into slavery, regardless of their father's ancestry. Similarly, Virginia denied that converting a slave to Christianity was grounds for freedom. Even free people of color or mixed-race (known as mulattoes) were restricted in their rights, especially as colonies passed harsher laws after early slave revolts. During the centuries of slavery in the British colonies, many slaves were of mixed-race ancestry.

Colonial slave rebellions before 1776, or before 1801 for Louisiana, include:

While the British knew about Spanish and Portuguese slave trading, they did not implement slave labor in the Americas until the 17th century. British travelers were fascinated by the dark-skinned people they found in West Africa; they developed mythologies that situated them in their view of the cosmos.

The first Africans to arrive in England came voluntarily in 1555 with John Lok (an ancestor of the famous philosopher John Locke). Lok intended to teach them English in order to facilitate the trading of material goods with West Africa. This model gave way to a slave trade initiated by John Hawkins, who captured 300 Africans and sold them to the Spanish. Blacks in England were subordinate but never had the legal status of chattel slaves.

In 1607, England established Jamestown as its first permanent colony on the North American continent. Tobacco became the chief commodity crop of the colony, due to the efforts of John Rolfe in 1611. Once it became clear that tobacco was going to drive the Jamestown economy, more workers were needed for the labor-intensive crop. The British aristocracy also needed to find a labor force to work on its sugar plantations in the Americas. The major sources were indentured servants from Britain, Native Americans, and West Africans. During this period, Barbados became an English Colony in 1624 and the Caribbean's Jamaica in 1655. These and other Caribbean colonies became the center of wealth generated from sugar cane and the focus of the slave trade for the growing English empire.

The English entertained two lines of thought simultaneously toward the indigenous Native Americans. Because these people were lighter-skinned, they were seen as more European and therefore as candidates for civilization. At the same time, because they were occupying the land desired by the colonial powers, they were from the beginning, targets of potential military attack.

At first, indentured servants were used as the needed labor. These servants provided up to seven years of service in exchange for having their trip to Jamestown paid for by someone in Jamestown. Once the seven years were over, the indentured servant was free to live in Jamestown as a regular citizen. However, colonists began to see indentured servants as too costly, in part because the high mortality rate meant the force had to be resupplied.

In 1619, Dutch traders brought African slaves taken from a Spanish ship to Point Comfort.

Several colonial colleges held enslaved people as workers and relied on them to operate.

The laws relating to slavery and their enforcement hardened in the second half of the 17th century, and the prospects for Africans and their descendants grew increasingly dim. By 1640, the Virginia courts had sentenced at least one black servant, John Punch, to slavery. In 1656 Elizabeth Key won a suit for freedom based on her father's status as a free Englishman, and his having baptized her as Christian in the Church of England. In 1662 the Virginia House of Burgesses passed a law with the doctrine of , stating that any child born in the colony would follow the status of its mother, bond or free. This was an overturn of a longheld principle of English Common Law, whereby a child's status followed that of the father. It enabled slaveholders and other white men to hide the mixed-race children born of their rape of slave women and removed their responsibility to acknowledge, support, or emancipate the children.

During the second half of the 17th century, the British economy improved and the supply of British indentured servants declined, as poor Britons had better economic opportunities at home. At the same time, Bacon's Rebellion of 1676 led planters to worry about the prospective dangers of creating a large class of restless, landless, and relatively poor white men (most of them former indentured servants). Wealthy Virginia and Maryland planters began to buy slaves in preference to indentured servants during the 1660s and 1670s, and poorer planters followed suit by c.1700. (Slaves cost more than servants, so initially only the wealthy could invest in slaves.) The first British colonists in Carolina introduced African slavery into the colony in 1670, the year the colony was founded, and Charleston ultimately became the busiest slave port in North America. Slavery spread from the South Carolina Lowcountry first to Georgia, then across the Deep South as Virginia's influence had crossed the Appalachians to Kentucky and Tennessee. Northerners also purchased slaves, though on a much smaller scale. Enslaved people outnumbered free whites in South Carolina from the early 1700s to the Civil War. An authoritarian political culture evolved to prevent slave rebellion and justify white slaveholding. Northern slaves typically dwelled in towns, rather than on plantations as in the South, and worked as artisans and artisans' assistants, sailors and longshoremen, and domestic servants.

In 1672, King Charles II rechartered the Royal African Company (it had initially been set up in 1660), as an English monopoly for the African slave and commodities trade-thereafter in 1698, by statute, the English parliament opened the trade to all English subjects. The slave trade to the mid-Atlantic colonies increased substantially in the 1680s, and by 1710 the African population in Virginia had increased to 23,100 (42% of total); Maryland contained 8,000 Africans (23% of total). In the early 18th century, England passed Spain and Portugal to become the world's leading slave-trader.

The North American royal colonies not only imported Africans but also captured Native Americans, impressing them into slavery. Many Native Americans were shipped as slaves to the Caribbean. Many of these slaves from the British colonies were able to escape by heading south, to the Spanish colony of Florida. There they were given their freedom if they declared their allegiance to the King of Spain and accepted the Catholic Church. In 1739 Fort Mose was established by African American freedmen and became the northern defense post for St. Augustine. In 1740, English forces attacked and destroyed the fort, which was rebuilt in 1752. Because Fort Mose became a haven for escaped slaves from the English colonies to the north, it is considered a precursor site of the Underground Railroad.

Chattel slavery developed in British North America before the full legal apparatus that supported slavery did. During the late 17th century and early 18th century, harsh new slave codes limited the rights of African slaves and cut off their avenues to freedom. The first full-scale slave code in British North America was South Carolina's (1696), which was modeled on the colonial Barbados slave code of 1661 and was updated and expanded regularly throughout the 18th century.

A 1691 Virginia law prohibited slaveholders from emancipating slaves unless they paid for the freedmen's transportation out of Virginia. Virginia criminalized interracial marriage in 1691, and subsequent laws abolished blacks' rights to vote, hold office, and bear arms. Virginia's House of Burgesses established the basic legal framework for slavery in 1705.

Of the enslaved Africans brought to the New World an estimated 5-7% ended up in British North America. The vast majority of slaves transported across the Atlantic Ocean were sent to the Caribbean sugar colonies, Brazil, or Spanish America. Throughout the Americas, but especially in the Caribbean, tropical disease took a large toll on their population and required large numbers of replacements. Many Africans had limited natural immunity to yellow fever and malaria; but malnutrition, poor housing, inadequate clothing allowances, and overwork contributed to a high mortality rate.

In British North America the slave population rapidly increased via the birth rate, whereas in the Caribbean colonies they did not. The lack of proper nourishment, being suppressed sexually, and poor health are possible reasons. Of the small numbers of babies born to slaves in the Caribbean, only about 1/4 survived the miserable conditions on sugar plantations.

It was not only the major colonial powers of Western Europe such as France, England, Spain, Portugal, and the Netherlands that were involved. Other countries, including Sweden and Denmark, participated in the trans- Atlantic slave trade though on a much more limited scale.

"Depending upon their age and gender, slaves were assigned a particular task, or tasks, that had to be completed during the course of the day." In certain settings, men would participate in the hard labor, such as working on the farm, while women would generally work in the household. They would "be sent out on errands but in most cases their jobs required that they spend much of their time within their owner's household." These gender distinctions were mainly applied in the Northern colonies and on larger plantations. In Southern colonies and smaller farms, however, women and men typically engaged in the same roles, both working in the tobacco crop fields for example.

Although slave women and men in some areas performed the same type of day-to-day work, "[t]he female slave...was faced with the prospect of being forced into sexual relationships for the purpose of reproduction." This reproduction would either be forced between one African slave and another, or between the slave woman and the owner. Slave owners saw slave women in terms of prospective fertility. That way, the number of slaves on a plantation could multiply without having to purchase another African. Unlike the patriarchal society of white Anglo-American colonists, "slave families" were more matriarchal in practice. "Masters believed that slave mothers, like white women, had a natural bond with their children that therefore it was their responsibility - more so than that of slave fathers - to care for their offspring." Therefore, women had the extra responsibility, on top of their other day-to-day work, to take care of children. Men, in turn, were often separated from their families. "At the same time that slaveholders promoted a strong bond between slave mothers and their children, they denied to slave fathers their paternal rights of ownership and authority..." Biological families were often separated by sale.

Some historians, notably Edmund Morgan, have suggested that indentured servitude provided a model for slavery in 17th-century Virginia. In practice, indentured servants were teenagers in England whose father sold their labor voluntarily for a period of time (typically four to seven years), in return for free passage to the colonies, room and board and clothes, and training in an occupation. After that, they received cash, clothing, tools, and/or land, and became ordinary settlers.

In 1688, four German Quakers in Germantown, a town outside Philadelphia, wrote a petition against the use of slaves by the English colonists in the nearby countryside. They presented the petition to their local Quaker Meeting, and the Meeting was sympathetic, but could not decide what the appropriate response should be. The Meeting passed the petition up the chain of authority to Philadelphia Yearly Meeting, where it continued to be ignored. It was archived and forgotten for 150 years.

The Quaker petition was the first public American document of its kind to protest slavery. It was also one of the first public declarations of universal human rights. While the petition was forgotten for a time, the idea that every human has equal rights were regularly discussed in Philadelphia Quaker society through the eighteenth century.

During the Great Awakening of the late eighteenth century, Methodist and Baptist preachers toured in the South, trying to persuade planters to manumit their slaves on the basis of equality in God's eyes. They also accepted slaves as members and preachers of new chapels and churches. The first black churches (all Baptist) in what became the United States were founded by slaves and free blacks in Aiken County, South Carolina in 1773, Petersburg, Virginia in 1774, and Savannah, Georgia in 1778, before the end of the Revolutionary War.

Slavery was officially sanctioned in 1776 by the Philadelphia Yearly Meeting.

In the early 21st century, new research has revealed that small numbers of East Indians were brought to the colonies as enslaved laborers, during the period when both India and the colonies were under British control. As an example, an ad in the Virginia Gazette of Aug. 4, 1768, describes one young "East Indian" as "a well made fellow, about 5 feet 4 inches high" who had "a thin visage, a very sly look, and a remarkable set of fine white teeth." Another slave is identified as "an East India negro man" who speaks French and English. Most of the Indian slaves were already converted to Christianity, were fluent in English, and took western names. Their original names and homes are not known. Their descendants have mostly merged with the African-American community, which also incorporated European ancestors. Today, descendants of such East Indian slaves may have a small percent of DNA from their Asiatic ancestors but it likely falls below the detectable levels for today's DNA tests.

African and African American slaves expressed their opposition to slavery through armed uprisings such as the Stono Rebellion (1739) in South Carolina. More typically, they resisted through work slowdowns, tool-breaking, and running away, either for short periods or permanently. Until the Revolutionary era, almost no white American colonists spoke out against slavery. Even the Quakers generally tolerated slaveholding (and slave-trading) until the mid-18th century, although they emerged as vocal opponents of slavery in the Revolutionary era.

During and following the Revolution, the northern states all abolished slavery, with New Jersey acting last in 1804. Some of these state jurisdictions enacted the first abolition laws in the entire New World. In states that passed gradual abolition laws, such as New York and New Jersey, children born to slave mothers had to serve an extended period of indenture into young adulthood. In other cases, some slaves were reclassified as indentured servants, effectively preserving the institution of slavery through another name.

Often citing Revolutionary ideals, some slaveholders freed their slaves in the first two decades after independence, either outright or through their wills. The proportion of free blacks rose markedly in the Upper South in this period, before the invention of the cotton gin created a new demand for slaves in the developing "Cotton Kingdom" of the Deep South.

By 1808 (the first year allowed by the Constitution to federally ban the import slave trade), all states (except South Carolina) had banned the international buying or selling of slaves. Acting on the advice of President Thomas Jefferson, who denounced the international trade as "violations of human rights which have been so long continued on the unoffending inhabitants of Africa, in which the morality, the reputation, and the best interests of our country have long been eager to proscribe", in 1807 Congress also banned the international slave trade. However, the domestic slave trade continued in the South. It brought great wealth to the South, especially to New Orleans, which became the fourth largest city in the country, also based on the growth of its port. In the antebellum years, more than one million enslaved African Americans were transported from the Upper South to the developing Deep South, mostly in the slave trade. Cotton culture, dependent on slavery, formed the basis of new wealth in the Deep South.

In 1844 the Quaker petition was rediscovered and became a focus of the burgeoning abolitionist movement.

On 1 January 1863, Abraham Lincoln signed Emancipation Proclamation freeing slaves in areas in rebellion during the American Civil War when Union troops advanced south. The Thirteenth Amendment (abolition of slavery and involuntary servitude) was ratified in December 1865.

Slavery in the colonial history of the United States, from 1600 to 1776, developed from complex factors, and researchers have proposed several theories to explain the development of the institution of slavery and of the slave trade. Slavery strongly correlated with Europe's American colonies' need for labor, especially for the labor-intensive plantation economies of the sugar colonies in the Caribbean, operated by Great Britain, France, Spain, and the Dutch Republic.

Most enslaved people who were ultimately brought to the Thirteen British colonies - the Eastern seaboard of what later became the United States - were imported from the Caribbean, not directly from Africa. They were taken to the Caribbean islands as a result of the Atlantic slave trade. Indigenous people were also enslaved in the North American colonies, but on a smaller scale, and Indian slavery largely ended in the late eighteenth century although the enslavement of Indigenous people did continue to occur in the Southern states until the Emancipation Proclamation issued by President Abraham Lincoln in 1863. In the English colonies, slave status for Africans became hereditary in the mid-17th century with the passage of colonial laws that defined children born in the colonies as taking the status of the mother, under the principle of partus sequitur ventrem.

Native Americans enslaved members of their own and other tribes before and after Europeans arrived, continuing into the 1800s; enslaved people might or might not be adopted eventually, especially if enslaved as children; and the enslavement might or might not be hereditary. Enslaved people included captives from wars and slave raids; captives bartered from other tribes, sometimes at great distances; children sold by their parents during famines; and men and women who staked themselves in gambling when they had nothing else, which put them into servitude in some cases for life.

Native Americans also captured and enslaved some early European explorers and colonists, and were enslaved themselves by the colonists, starting with the Spanish in the 1500s. Native Americans were enslaved by Spanish in Florida under the encomienda system. New England and the Carolinas captured Native Americans in wars and distributed them as slaves.

Larger societies structured as chiefdoms kept slaves as unpaid field laborers, while in band societies the ownership of enslaved captives attested to their captor's military prowess. Some war captives were also subjected to ritualized torture and execution. Alan Gallay and other historians emphasize differences between Native American enslavement of war captives and the European slave trading system, into which numerous native peoples were integrated.

Richard White, in The Middle Ground elucidates the complex social relationships between Native American groups and the early empires, including 'slave' culture and scalping. Robbie Ethridge states,

"Let there be no doubt...that the commercial trade in Indian slaves was not a continuation and adaptation of pre-existing captivity patterns. It was a new kind of slave, requiring a new kind of occupational specialty...organized militaristic slavers."

One example of this militaristic slaving can be seen in Nathaniel Bacon's actions in Virginia during the late 1670s. In June 1676, the Virginia assembly granted Bacon and his men what equated to a slave-hunting license by providing that any enemy Native Americans caught were to be slaves for life. They also provided soldiers who had captured Native Americans with the right to "retain and keep all such Native American slaves or other Native American goods as they either have taken or hereafter shall take." By this order, the assembly had made a public decision to enslave Native Americans. In the years to follow, other laws resulted in Native Americans being grouped with other non-Christian servants who had imported to the colonies (Negro slaves) as slaves for life.

Puritan New England, Virginia, Spanish Florida, and the Carolina colonies engaged in large-scale[citation needed ] enslavement of Native Americans, often through the use of Indian proxies to wage war and acquire the slaves. In New England, slave raiding accompanied the Pequot War and King Philip's War but declined after the latter war ended in 1676. Enslaved Native Americans were in Jamestown from the early years of the settlement,[citation needed ] but large-scale cooperation between English slavers and the West and Occaneechi peoples, whom they armed with guns, did not begin until the 1640s. These groups conducted enslaving raids in what is now Georgia, Tennessee, North Carolina, South Carolina, Florida, and possibly Alabama. The Carolina slave trade, which included both trading and direct raids by colonists, was the largest among the British colonies in North America, estimated at 24,000 to 51,000 Native Americans by Gallay.

Historian Ulrich Phillips argues that Africans were inculcated as slaves and the best answer to the labor shortage in the New World because Native American slaves were more familiar with the environment, and would often successfully escape into the wilderness that African slaves had much more difficulty surviving in. Also, early colonial America depended heavily on the sugar trade, which led to malaria, a disease the Africans were far less susceptible to than Native American slaves.

The first African slaves in what would become the present day United States of America arrived in 1526 with Lucas Vázquez de Ayllón's establishment of San Miguel de Gualdape on the current Georgia or Carolina coast. They rebelled and lived with indigenous people, destroying the colony in less than 2 months.

Georgia was the last of the Thirteen Colonies to be established and the furthest south (Florida was not one of the Thirteen Colonies). Founded in the 1730s, Georgia's powerful backers did not object to slavery as an institution, but their business model was to rely on labor from Britain (primarily England's poor) and they were also concerned with security, given the closeness of then Spanish Florida, and Spain's regular offers to enemy-slaves to revolt or escape. Despite agitation for slavery, it was not until a defeat of the Spanish by Georgia colonials in the 1740s that arguments for opening the colony to slavery intensified. To staff the rice plantations and settlements, Georgia's proprietors relented in 1751, and African slavery grew quickly. After becoming a royal colony, in the 1760s Georgia began importing slaves directly from Africa.

When St. Augustine, FL, was founded in 1565, the site already had enslaved Native Americans, whose ancestors had migrated from Cuba. The Spanish introduced African slaves in what is now Florida soon after they claimed the area in 1513. The Spanish settlement was sparse and they held comparatively few slaves. African slaves arrived in Florida in 1539 with Hernando de Soto, and in the 1565 founding of St. Augustine, Florida.

The Spanish promised freedom to refugee slaves from the English colonies of South Carolina and Georgia in order to destabilize English settlement. If the slaves converted to Catholicism and agreed to serve in a militia for Spain, they could become Spanish citizens. By 1730 the black settlement known as Fort Mose developed near St. Augustine and was later fortified. There were two known Fort Mose sites in the eighteenth century, and the men helped defend St. Augustine against the British. It is "the only known free black town in the present-day southern United States that a European colonial government-sponsored. The Fort Mose Site, today a National Historic Landmark, is the location of the second Fort Mose." During the nineteenth century, this site became marsh and wetlands.

In 1763, Great Britain took over Florida in an exchange with Spain after defeating France in the Seven Years' War. Spain evacuated its citizens from St. Augustine, including the residents of Fort Mose, transporting them to Cuba. As Britain developed the colony for plantation agriculture, the percentage of slaves in the population in twenty years rose from 18% to almost 65% by 1783.

The first recorded Africans in Virginia arrived in late August 1619. The , a privateer ship owned by Robert Rich, 2nd Earl of Warwick but flying a Dutch flag, docked at what is now Old Point Comfort (located in modern-day Hampton) with approximately 20 Africans. They were captives from the area of present-day Angola and had been seized by the British crew from a Portuguese slave ship, the "São João Bautista". To obtain the Africans, the Jamestown colony traded provisions with the ship. These individuals appear to have been treated as indentured servants, since slave laws were not passed until later, in 1641 in Massachusetts and in 1661 in Virginia.

Some number of the colony's early Africans earned freedom by fulfilling a work contract or for converting to Christianity. At least one of these, Anthony Johnson, in turn, acquired slaves or indentured servants for workers himself. Historians such as Edmund Morgan say this evidence suggests that racial attitudes were much more flexible in early 17th-century Virginia than they would later become. A 1625 census recorded 23 Africans in Virginia. In 1649 there were 300, and in 1690 there were 950. Over this period, legal distinctions between white indentured servants and "Negros" widened into lifelong and inheritable chattel-slavery for Africans.

Until the early 18th century, enslaved Africans were difficult to acquire in the colonies that became the United States, as most were sold to the West Indies, where the large plantations and high mortality rates required continued importation of slaves. One of the first major centers of African slavery in the English North American colonies occurred with the founding of Charles Town and the Province of Carolina in 1670. The colony was founded mainly by planters from the overpopulated English sugar island of Barbados, who brought relatively large numbers of African slaves from that island to establish new plantations.

To meet agricultural labor needs, colonists also practiced Indian slavery for some time. The Carolinians transformed the Indian slave trade during the late 17th and early 18th centuries by treating such slaves as a trade commodity to be exported, mainly to the West Indies. Historian Alan Gallay estimates that between 1670 and 1715, between 24,000 and 51,000 captive Native Americans were exported from South Carolina-much more than the number of Africans imported to the colonies of the future United States during the same period.

Slaves, African and Native American, made up a smaller part of the New England economy, which was based on yeoman farming and trades, and a smaller fraction of the population, but they were present. The Puritans codified slavery in 1641. The Massachusetts royal colony passed the Body of Liberties, which prohibited slavery in some instances, but did allow three legal bases of slavery. Slaves could be held if they were captives of war if they sold themselves into slavery, were purchased from elsewhere, or if they were sentenced to slavery by the governing authority. The Body of Liberties used the word "strangers" to refer to people bought and sold as slaves, as they were generally not English subjects. Colonists came to equate this term with Native Americans and Africans.

The Dutch West India Company introduced slavery in 1625 with the importation of eleven enslaved blacks who worked as farmers, fur traders, and builders to New Amsterdam (present day New York City), capital of the nascent province of New Netherland. The Dutch colony expanded across the North River (Hudson River) to Bergen (in today's New Jersey). Later, slaves were also held privately by settlers in the area. Although enslaved, the Africans had a few basic rights and families were usually kept intact. They were admitted to the Dutch Reformed Church and married by its ministers, and their children could be baptized. Slaves could testify in court, sign legal documents, and bring civil actions against whites. Some were permitted to work after hours earning wages equal to those paid to white workers. When the colony fell to the English in the 1660s, the company freed all its slaves, which created an early nucleus of free Negros in the area.

The English continued to import more slaves. Enslaved Africans performed a wide variety of skilled and unskilled jobs, mostly in the burgeoning port city and surrounding agricultural areas. In 1703 more than 42% of New York City's households held slaves, a percentage higher than in the cities of Boston and Philadelphia, and second only to Charleston in the South.

Midwest, Mississippi River, and Louisiana

The French introduced legalized slavery into their colonies in New France both near the Great Lakes and the Mississippi River. (They also used slave labor on their island colonies in the Caribbean: Guadeloupe and especially Saint-Domingue.) After the port of New Orleans was founded in 1718 with access to the Gulf Coast, French colonists imported more African slaves to the Illinois Country for use as agricultural or mining laborers. By the mid-eighteenth century, slaves accounted for as many as a third of the limited population in that rural area.

Slavery was much more extensive in colonial Louisiana, where the French developed sugar cane plantations along the Mississippi River. Slavery was maintained during the French (1699 - 1763, and 1800 - 1803) and Spanish (1763 - 1800) periods of government. The first people enslaved by the French were Native Americans, but they could easily escape into the countryside which they knew well. Beginning in the early 18th century, the French imported Africans as laborers in their efforts to develop the colony. Mortality rates were high for both colonists and Africans, and new workers had to be imported.

Implemented in colonial Louisiana in 1724, Louis XIV of France's regulated the slave trade and the institution of slavery in the French colonies. As a result, Louisiana and the Mobile area developed very different patterns of slavery compared to the British colonies. As written, the Code Noir gave some rights to slaves, including the right to marry. Although it authorized and codified cruel corporal punishment against slaves under certain conditions, it forbade slave owners to torture slaves, to separate married couples (and to separate young children from their mothers). It required owners to instruct slaves in the Catholic faith, implying that Africans were human beings endowed with a soul, an idea that had not been acknowledged until then.

The Code Noir forbade interracial marriages, but interracial relationships were formed in La Louisiane from the earliest years. In New Orleans society particularly, a formal system of concubinage, known as , developed. Usually formed between young white men and African or African-American women, these relationships were formalized with contracts that sometimes provided for freedom for a woman and her children (if she was still enslaved), education for the mixed-race children of the union, and sometimes a property settlement. The free people of color became an intermediate social caste between the whites and the mass of enslaved blacks; many practiced artisan trades, and some acquired educations and property.

Gradually in the English colonies, slavery became known as a racial caste that generally encompassed all people of African descent, even if mixed race. From the 17th century, Virginia defined all children born to enslaved mothers as born into slavery, regardless of their father's ancestry. Similarly, Virginia denied that converting a slave to Christianity was grounds for freedom. Even free people of color or mixed-race (known as mulattoes) were restricted in their rights, especially as colonies passed harsher laws after early slave revolts. During the centuries of slavery in the British colonies, many slaves were of mixed-race ancestry.

Colonial slave rebellions before 1776, or before 1801 for Louisiana, include:

While the British knew about Spanish and Portuguese slave trading, they did not implement slave labor in the Americas until the 17th century. British travelers were fascinated by the dark-skinned people they found in West Africa; they developed mythologies that situated them in their view of the cosmos.

The first Africans to arrive in England came voluntarily in 1555 with John Lok (an ancestor of the famous philosopher John Locke). Lok intended to teach them English in order to facilitate the trading of material goods with West Africa. This model gave way to a slave trade initiated by John Hawkins, who captured 300 Africans and sold them to the Spanish. Blacks in England were subordinate but never had the legal status of chattel slaves.

In 1607, England established Jamestown as its first permanent colony on the North American continent. Tobacco became the chief commodity crop of the colony, due to the efforts of John Rolfe in 1611. Once it became clear that tobacco was going to drive the Jamestown economy, more workers were needed for the labor-intensive crop. The British aristocracy also needed to find a labor force to work on its sugar plantations in the Americas. The major sources were indentured servants from Britain, Native Americans, and West Africans. During this period, Barbados became an English Colony in 1624 and the Caribbean's Jamaica in 1655. These and other Caribbean colonies became the center of wealth generated from sugar cane and the focus of the slave trade for the growing English empire.

The English entertained two lines of thought simultaneously toward the indigenous Native Americans. Because these people were lighter-skinned, they were seen as more European and therefore as candidates for civilization. At the same time, because they were occupying the land desired by the colonial powers, they were from the beginning, targets of potential military attack.

At first, indentured servants were used as the needed labor. These servants provided up to seven years of service in exchange for having their trip to Jamestown paid for by someone in Jamestown. Once the seven years were over, the indentured servant was free to live in Jamestown as a regular citizen. However, colonists began to see indentured servants as too costly, in part because the high mortality rate meant the force had to be resupplied.

In 1619, Dutch traders brought African slaves taken from a Spanish ship to Point Comfort.

Several colonial colleges held enslaved people as workers and relied on them to operate.

The laws relating to slavery and their enforcement hardened in the second half of the 17th century, and the prospects for Africans and their descendants grew increasingly dim. By 1640, the Virginia courts had sentenced at least one black servant, John Punch, to slavery. In 1656 Elizabeth Key won a suit for freedom based on her father's status as a free Englishman, and his having baptized her as Christian in the Church of England. In 1662 the Virginia House of Burgesses passed a law with the doctrine of , stating that any child born in the colony would follow the status of its mother, bond or free. This was an overturn of a longheld principle of English Common Law, whereby a child's status followed that of the father. It enabled slaveholders and other white men to hide the mixed-race children born of their rape of slave women and removed their responsibility to acknowledge, support, or emancipate the children.

During the second half of the 17th century, the British economy improved and the supply of British indentured servants declined, as poor Britons had better economic opportunities at home. At the same time, Bacon's Rebellion of 1676 led planters to worry about the prospective dangers of creating a large class of restless, landless, and relatively poor white men (most of them former indentured servants). Wealthy Virginia and Maryland planters began to buy slaves in preference to indentured servants during the 1660s and 1670s, and poorer planters followed suit by c.1700. (Slaves cost more than servants, so initially only the wealthy could invest in slaves.) The first British colonists in Carolina introduced African slavery into the colony in 1670, the year the colony was founded, and Charleston ultimately became the busiest slave port in North America. Slavery spread from the South Carolina Lowcountry first to Georgia, then across the Deep South as Virginia's influence had crossed the Appalachians to Kentucky and Tennessee. Northerners also purchased slaves, though on a much smaller scale. Enslaved people outnumbered free whites in South Carolina from the early 1700s to the Civil War. An authoritarian political culture evolved to prevent slave rebellion and justify white slaveholding. Northern slaves typically dwelled in towns, rather than on plantations as in the South, and worked as artisans and artisans' assistants, sailors and longshoremen, and domestic servants.

In 1672, King Charles II rechartered the Royal African Company (it had initially been set up in 1660), as an English monopoly for the African slave and commodities trade-thereafter in 1698, by statute, the English parliament opened the trade to all English subjects. The slave trade to the mid-Atlantic colonies increased substantially in the 1680s, and by 1710 the African population in Virginia had increased to 23,100 (42% of total); Maryland contained 8,000 Africans (23% of total). In the early 18th century, England passed Spain and Portugal to become the world's leading slave-trader.

The North American royal colonies not only imported Africans but also captured Native Americans, impressing them into slavery. Many Native Americans were shipped as slaves to the Caribbean. Many of these slaves from the British colonies were able to escape by heading south, to the Spanish colony of Florida. There they were given their freedom if they declared their allegiance to the King of Spain and accepted the Catholic Church. In 1739 Fort Mose was established by African American freedmen and became the northern defense post for St. Augustine. In 1740, English forces attacked and destroyed the fort, which was rebuilt in 1752. Because Fort Mose became a haven for escaped slaves from the English colonies to the north, it is considered a precursor site of the Underground Railroad.

Chattel slavery developed in British North America before the full legal apparatus that supported slavery did. During the late 17th century and early 18th century, harsh new slave codes limited the rights of African slaves and cut off their avenues to freedom. The first full-scale slave code in British North America was South Carolina's (1696), which was modeled on the colonial Barbados slave code of 1661 and was updated and expanded regularly throughout the 18th century.

A 1691 Virginia law prohibited slaveholders from emancipating slaves unless they paid for the freedmen's transportation out of Virginia. Virginia criminalized interracial marriage in 1691, and subsequent laws abolished blacks' rights to vote, hold office, and bear arms. Virginia's House of Burgesses established the basic legal framework for slavery in 1705.

Of the enslaved Africans brought to the New World an estimated 5-7% ended up in British North America. The vast majority of slaves transported across the Atlantic Ocean were sent to the Caribbean sugar colonies, Brazil, or Spanish America. Throughout the Americas, but especially in the Caribbean, tropical disease took a large toll on their population and required large numbers of replacements. Many Africans had limited natural immunity to yellow fever and malaria; but malnutrition, poor housing, inadequate clothing allowances, and overwork contributed to a high mortality rate.

In British North America the slave population rapidly increased via the birth rate, whereas in the Caribbean colonies they did not. The lack of proper nourishment, being suppressed sexually, and poor health are possible reasons. Of the small numbers of babies born to slaves in the Caribbean, only about 1/4 survived the miserable conditions on sugar plantations.

It was not only the major colonial powers of Western Europe such as France, England, Spain, Portugal, and the Netherlands that were involved. Other countries, including Sweden and Denmark, participated in the trans- Atlantic slave trade though on a much more limited scale.

"Depending upon their age and gender, slaves were assigned a particular task, or tasks, that had to be completed during the course of the day." In certain settings, men would participate in the hard labor, such as working on the farm, while women would generally work in the household. They would "be sent out on errands but in most cases their jobs required that they spend much of their time within their owner's household." These gender distinctions were mainly applied in the Northern colonies and on larger plantations. In Southern colonies and smaller farms, however, women and men typically engaged in the same roles, both working in the tobacco crop fields for example.

Although slave women and men in some areas performed the same type of day-to-day work, "[t]he female slave...was faced with the prospect of being forced into sexual relationships for the purpose of reproduction." This reproduction would either be forced between one African slave and another, or between the slave woman and the owner. Slave owners saw slave women in terms of prospective fertility. That way, the number of slaves on a plantation could multiply without having to purchase another African. Unlike the patriarchal society of white Anglo-American colonists, "slave families" were more matriarchal in practice. "Masters believed that slave mothers, like white women, had a natural bond with their children that therefore it was their responsibility - more so than that of slave fathers - to care for their offspring." Therefore, women had the extra responsibility, on top of their other day-to-day work, to take care of children. Men, in turn, were often separated from their families. "At the same time that slaveholders promoted a strong bond between slave mothers and their children, they denied to slave fathers their paternal rights of ownership and authority..." Biological families were often separated by sale.

Some historians, notably Edmund Morgan, have suggested that indentured servitude provided a model for slavery in 17th-century Virginia. In practice, indentured servants were teenagers in England whose father sold their labor voluntarily for a period of time (typically four to seven years), in return for free passage to the colonies, room and board and clothes, and training in an occupation. After that, they received cash, clothing, tools, and/or land, and became ordinary settlers.

In 1688, four German Quakers in Germantown, a town outside Philadelphia, wrote a petition against the use of slaves by the English colonists in the nearby countryside. They presented the petition to their local Quaker Meeting, and the Meeting was sympathetic, but could not decide what the appropriate response should be. The Meeting passed the petition up the chain of authority to Philadelphia Yearly Meeting, where it continued to be ignored. It was archived and forgotten for 150 years.

The Quaker petition was the first public American document of its kind to protest slavery. It was also one of the first public declarations of universal human rights. While the petition was forgotten for a time, the idea that every human has equal rights were regularly discussed in Philadelphia Quaker society through the eighteenth century.

During the Great Awakening of the late eighteenth century, Methodist and Baptist preachers toured in the South, trying to persuade planters to manumit their slaves on the basis of equality in God's eyes. They also accepted slaves as members and preachers of new chapels and churches. The first black churches (all Baptist) in what became the United States were founded by slaves and free blacks in Aiken County, South Carolina in 1773, Petersburg, Virginia in 1774, and Savannah, Georgia in 1778, before the end of the Revolutionary War.

Slavery was officially sanctioned in 1776 by the Philadelphia Yearly Meeting.

In the early 21st century, new research has revealed that small numbers of East Indians were brought to the colonies as enslaved laborers, during the period when both India and the colonies were under British control. As an example, an ad in the Virginia Gazette of Aug. 4, 1768, describes one young "East Indian" as "a well made fellow, about 5 feet 4 inches high" who had "a thin visage, a very sly look, and a remarkable set of fine white teeth." Another slave is identified as "an East India negro man" who speaks French and English. Most of the Indian slaves were already converted to Christianity, were fluent in English, and took western names. Their original names and homes are not known. Their descendants have mostly merged with the African-American community, which also incorporated European ancestors. Today, descendants of such East Indian slaves may have a small percent of DNA from their Asiatic ancestors but it likely falls below the detectable levels for today's DNA tests.

African and African American slaves expressed their opposition to slavery through armed uprisings such as the Stono Rebellion (1739) in South Carolina. More typically, they resisted through work slowdowns, tool-breaking, and running away, either for short periods or permanently. Until the Revolutionary era, almost no white American colonists spoke out against slavery. Even the Quakers generally tolerated slaveholding (and slave-trading) until the mid-18th century, although they emerged as vocal opponents of slavery in the Revolutionary era.

During and following the Revolution, the northern states all abolished slavery, with New Jersey acting last in 1804. Some of these state jurisdictions enacted the first abolition laws in the entire New World. In states that passed gradual abolition laws, such as New York and New Jersey, children born to slave mothers had to serve an extended period of indenture into young adulthood. In other cases, some slaves were reclassified as indentured servants, effectively preserving the institution of slavery through another name.

Often citing Revolutionary ideals, some slaveholders freed their slaves in the first two decades after independence, either outright or through their wills. The proportion of free blacks rose markedly in the Upper South in this period, before the invention of the cotton gin created a new demand for slaves in the developing "Cotton Kingdom" of the Deep South.

By 1808 (the first year allowed by the Constitution to federally ban the import slave trade), all states (except South Carolina) had banned the international buying or selling of slaves. Acting on the advice of President Thomas Jefferson, who denounced the international trade as "violations of human rights which have been so long continued on the unoffending inhabitants of Africa, in which the morality, the reputation, and the best interests of our country have long been eager to proscribe", in 1807 Congress also banned the international slave trade. However, the domestic slave trade continued in the South. It brought great wealth to the South, especially to New Orleans, which became the fourth largest city in the country, also based on the growth of its port. In the antebellum years, more than one million enslaved African Americans were transported from the Upper South to the developing Deep South, mostly in the slave trade. Cotton culture, dependent on slavery, formed the basis of new wealth in the Deep South.

In 1844 the Quaker petition was rediscovered and became a focus of the burgeoning abolitionist movement.

On 1 January 1863, Abraham Lincoln signed Emancipation Proclamation freeing slaves in areas in rebellion during the American Civil War when Union troops advanced south. The Thirteenth Amendment (abolition of slavery and involuntary servitude) was ratified in December 1865.

The history of slavery spans many cultures, nationalities, and religions from ancient times to the present day. However the social, economic, and legal positions of slaves have differed vastly in different systems of slavery in different times and places.

Slavery occurs relatively rarely among hunter-gatherer populations because it develops under conditions of social stratification. Slavery operated in the very first civilizations (such as Sumer in Mesopotamia, which dates back as far as 3500 BCE). Slavery features in the Mesopotamian Code of Hammurabi (c. 1860 BCE), which refers to it as an established institution. Slavery became common within much of Europe during the Early Middle Ages and it continued into the following centuries. The Byzantine-Ottoman wars (1265-1479) and the Ottoman wars in Europe (14th to 20th centuries) resulted in the capture of large numbers of Christian slaves. The Dutch, French, Spanish, Portuguese, British, Arabs and a number of West African kingdoms played a prominent role in the Atlantic slave trade, especially after 1600. The Republic of Ragusa became the first European country to ban the slave trade in 1416. In modern times Denmark-Norway abolished the trade in 1802.

Although slavery is no longer legal anywhere in the world (with the exception of penal labour), human trafficking remains an international problem and an estimated 25-40 million people were enslaved as of 2013, the majority in Asia. During the 1983-2005 Second Sudanese Civil War people were taken into slavery. Evidence emerged in the late 1990s of systematic child-slavery and -trafficking on cacao plantations in West Africa. Slavery continues into the 21st century. Although Mauritania criminalized slavery in August 2007, an estimated up to 600,000 men, women and children, or 20% of the population of Mauritania, are currently enslaved, many of them used as bonded labor. Slavery in the 21st century continues, with the top ten countries with the highest prevalence according to the Global Slavery Index being North Korea, Eritrea, Burundi, the Central African Republic, Afghanistan, Mauritania, South Sudan, Pakistan, Cambodia and Iran. Islamist quasi-states such as the Islamic State of Iraq and the Levant and Boko Haram have abducted and enslaved women and children (often to serve as sex slaves).

Evidence of slavery predates written records, and has existed in many cultures. Mass slavery requires economic surpluses and a high population density to be viable. Due to these factors, the practice of slavery would have only proliferated after the invention of agriculture during the Neolithic Revolution, about 11,000 years ago.

C. 1480 BCE, fugitive slave treaty between Idrimi of Alakakh (now Tell Atchana) and Pillia of Kizzuwatna (now Cilicia).

French historian Fernand Braudel noted that slavery was endemic in Africa and part of the structure of everyday life. "Slavery came in different guises in different societies: there were court slaves, slaves incorporated into princely armies, domestic and household slaves, slaves working on the land, in industry, as couriers and intermediaries, even as traders". During the 16th century, Europe began to outpace the Arab world in the export traffic, with its slave traffic from Africa to the Americas. The Dutch imported slaves from Asia into their colony in South Africa. In 1807 Britain, which held extensive, although mainly coastal, colonial territories on the African continent (including southern Africa), made the international slave trade illegal, as did the United States in 1808.

Slavery in Ethiopia persisted until 1942. The Anti-Slavery Society estimated that there were 2,000,000 slaves in the early 1930s, out of an estimated population of between 8 and 16 million. It was finally abolished by order of emperor Haile Selassie on 26 August 1942.

When British rule was first imposed on the Sokoto Caliphate and the surrounding areas in northern Nigeria at the turn of the 20th century, approximately 2 million to 2.5 million people there were slaves. Slavery in northern Nigeria was finally outlawed in 1936.

Elikia M'bokolo, April 1998, Le Monde diplomatique. Quote: "The African continent was bled of its human resources via all possible routes. Across the Sahara, through the Red Sea, from the Indian Ocean ports and across the Atlantic. At least ten centuries of slavery for the benefit of the Muslim countries (from the ninth to the nineteenth)." He continues: "Four million slaves exported via the Red Sea, another four million through the Swahili ports of the Indian Ocean, perhaps as many as nine million along the trans-Saharan caravan route, and eleven to twenty million (depending on the author) across the Atlantic Ocean"

Zanzibar was once East Africa's main slave-trading port, and under Omani Arabs in the 19th century, as many as 50,000 slaves were passing through the city each year.

Prior to the 16th century, the bulk of slaves exported from Africa were shipped from East Africa to the Arabian peninsula. Zanzibar became a leading port in this trade. Arab slave traders differed from European ones in that they would often conduct raiding expeditions themselves, sometimes penetrating deep into the continent. They also differed in that their market greatly preferred the purchase of female slaves over male ones.

The increased presence of European rivals along the East coast led Arab traders to concentrate on the overland slave caravan routes across the Sahara from the Sahel to North Africa. The German explorer Gustav Nachtigal reported seeing slave caravans departing from Kukawa in Bornu bound for Tripoli and Egypt in 1870. The slave trade represented the major source of revenue for the state of Bornu as late as 1898. The eastern regions of the Central African Republic have never recovered demographically from the impact of 19th-century raids from the Sudan and still have a population density of less than 1 person/km². During the 1870s, European initiatives against the slave trade caused an economic crisis in northern Sudan, precipitating the rise of Mahdist forces. Mahdi's victory created an Islamic state, one that quickly reinstituted slavery.

The Middle Passage, the crossing of the Atlantic to the Americas, endured by slaves laid out in rows in the holds of ships, was only one element of the well-known triangular trade engaged in by Portuguese, Dutch, Danish-Norwegians, French, British and others. Ships having landed slaves in Caribbean ports would take on sugar, indigo, raw cotton, and later coffee, and make for Liverpool, Nantes, Lisbon or Amsterdam. Ships leaving European ports for West Africa would carry printed cotton textiles, some originally from India, copper utensils and bangles, pewter plates and pots, iron bars more valued than gold, hats, trinkets, gunpowder and firearms and alcohol. Tropical shipworms were eliminated in the cold Atlantic waters, and at each unloading, a profit was made.

While talking about the slave trade in East Africa in his journals, "To overdraw its evil is a simple impossibility."

To overdraw its evil is a simple impossibility.

David Livingstone while travelling in the African Great Lakes Region in 1866 described a trail of slaves as such:

19th June 1866 - We passed a woman tied by the neck to a tree and dead, the people of the country explained that she had been unable to keep up with the other slaves in a gang, and her master had determined that she should not become anyone's property if she recovered.
26th June. - ...We passed a slave woman shot or stabbed through the body and lying on the path: a group of men stood about a hundred yards off on one side, and another of the women on the other side, looking on; they said an Arab who passed early that morning had done it in anger at losing the price he had given for her, because she was unable to walk any longer.
27th June 1866 - To-day we came upon a man dead from starvation, as he was very thin. One of our men wandered and found many slaves with slave-sticks on, abandoned by their masters from want of food; they were too weak to be able to speak or say where they had come from; some were quite young.

The strangest disease I have seen in this country seems really to be broken-heartedness, and it attacks free men who have been captured and made slaves... Twenty one were unchained, as now safe; however all ran away at once; but eight with many others still in chains, died in three days after the crossing. They described their only pain in the heart, and placed the hand correctly on the spot, though many think the organ stands high up in the breast-bone.

African states played a role in the slave trade, and slavery was a common practice among Sub Saharan Africans before the involvement of the Arabs, Berbers and Europeans. There were three types: those who were slaves through conquest, those who were slaves due to unpaid debts, or those whose parents gave them as slaves to tribal chiefs. Chieftains would barter their slaves to Arab, Berber, Ottoman or European buyers for rum, spices, cloth or other goods. Selling captives or prisoners was commonly practiced among Africans, Turks, Berbers and Arabs during that era. However, as the Atlantic slave trade increased its demand, local systems which primarily serviced indentured servitude expanded. European slave trading, as a result, was the most pivotal change in the social, economic, cultural, spiritual, religious, political dynamics of the concept of slave trading. It ultimately undermined local economies and political stability as villages' vital labour forces were shipped overseas as slave raids and civil wars became commonplace. Crimes which were previously punishable by some other means became punishable by enslavement.

The kings of Dahomey sold their war captives into transatlantic slavery, who otherwise may have been killed in a ceremony known as the Annual Customs. As one of West Africa's principal slave states, Dahomey became extremely unpopular with neighbouring peoples. Like the Bambara Empire to the east, the Khasso kingdoms depended heavily on the slave trade for their economy. A family's status was indicated by the number of slaves it owned, leading to wars for the sole purpose of taking more captives. This trade led the Khasso into increasing contact with the European settlements of Africa's west coast, particularly the French. Benin grew increasingly rich during the 16th and 17th centuries on the slave trade with Europe; slaves from enemy states of the interior were sold, and carried to the Americas in Dutch and Portuguese ships. The Bight of Benin's shore soon came to be known as the "Slave Coast".

The slave trade is the ruling principle of my people. It is the source and the glory of their wealth...the mother lulls the child to sleep with notes of triumph over an enemy reduced to slavery...

In 1807, under internal and external pressures, the United Kingdom made illegal the international trade in slaves. The Royal Navy was deployed to prevent slavers from the United States, France, Spain, Portugal, Holland, West Africa and Arabia. The King of Bonny (now in Nigeria) allegedly became dissatisfied of the British intervention in stopping slave trading.

We think this trade must go on. That is the verdict of our oracle and the priests. They say that your country, however great, can never stop a trade ordained by God himself.

Joseph Miller states that African buyers would prefer males, but in reality, women and children would be more easily captured as men fled. Those captured would be sold for various reasons such as food, debts, or servitude. Once captured, the journey to the coast killed many and weakened others. Disease engulfed many, and insufficient food damaged those who made it to the coasts. Scurvy was so common that it was known as mal de Luanda (Luanda sickness). The assumption for those who died on the journey died from malnutrition. As food was limited, water may have been just as bad. Dysentery was widespread and poor sanitary conditions at ports did not help. Since supplies were poor, slaves were not equipped with the best clothing that further exposed to more diseases.

If the fear of disease caused terror, the psyche of slaves for being captured was just as terrifying. The most popular assumption for being captured was Europeans were cannibals. Stories and rumours spread that whites captured Africans to eat them. Olaudah Equiano accounts his experience about the sorrow slaves encountered at the ports. He talks about his first moment on a slave ship and asked if he was going to be eaten. Yet, the worst for slaves has only begun, and the journey on the water proved to be more terrifying. For every 100 Africans captured, only 64 would reach the coast, and only about 50 would reach the New World.

Others believe that slavers had a vested interest in capturing rather than killing, and in keeping their captives alive; and that this coupled with the disproportionate removal of males and the introduction of new crops from the Americas ( cassava, maize) would have limited general population decline to particular regions of western Africa around 1760-1810, and in Mozambique and neighbouring areas half a century later. There has also been speculation that within Africa, females were most often captured as brides, with their male protectors being a "bycatch" who would have been killed if there had not been an export market for them.

British explorer Mungo Park encountered a group of slaves when traveling through Mandinka country:

They were all very inquisitive, but they viewed me at first with looks of horror, and repeatedly asked if my countrymen were cannibals. They were very desirous to know what became of the slaves after they had crossed the salt water. I told them that they were employed in cultivation the land; but they would not believe me ... A deeply-rooted idea that the whites purchase negroes for the purpose of devouring them, or of selling them to others that they may be devoured hereafter, naturally makes the slaves contemplate a journey towards the coast with great terror, insomuch that the slatees are forced to keep them constantly in irons, and watch them very closely, to prevent their escape.

During the period from the late 19th century and early 20th century, demand for the labour-intensive harvesting of rubber drove frontier expansion and forced labour. The personal monarchy of Belgian King Leopold II in the Congo Free State saw mass killings and slavery to extract rubber.

Stephanie Smallwood in her book Saltwater Slavery uses Equiano's account on board ships to describe the general thoughts of most slaves.

Then," said I, "how comes it in all our country we never heard of them?" They told me because they lived so very far off. I then asked where were their women? Had they any like themselves? I was told that they had. "And why," said I, "do we not see them?" They answered, because they were left behind. I asked how the vessel could go? They told me they could not tell; but that there was cloth put upon the masts by the help of the ropes I saw, and then the vessel went on; and the white men had some spell or magic they put in the water when they liked, in order to stop the vessel. I was exceedingly amazed at this account, and really thought they were spirits. I there-fore wished much to be from amongst them, for I expected they would sacrifice me; but my wishes were vain-for we were so quartered that it was impossible for any of us to make our escape.

Accounts like these raised many questions as some slaves grew philosophical with their journey. Smallwood points out the challenges for slaves were physical and metaphysical. The physical would be obvious as the challenge to overcome capacity, lack of ship room, and food. The metaphysical was unique as the open sea would challenge African slaves' vision of the ocean as habitable. At essence, the journey on the ocean would prove to be an African's biggest fear that would keep them in awe. Combining this with the lack of knowledge of the sea, Africans would be entering a world of anxiety never seen before. Yet, Europeans were also fearful of the sea, but not to the extent of Africans. One of these dilemmas came with the sense of time. Africans used seasonal weather to predict time and days. The moon was a sense of time, but used like in other cultures. On the sea, Africans used the moon to best count the days, but the sea did not provide seasonal changes for them to know how long they were at sea. Counting the days on a ship was not the main priority, however. Surviving the voyage was the main horror. No one escaped diseases as the close quarters infected everyone including the crew. Death was so common that ships were called tumbeiros or floating tombs. What shocked Africans the most was how death was handled in the ships. Smallwood says the traditions for an African death was delicate and community-based. On ships, bodies would be thrown into the sea. Because the sea represented bad omens, bodies in the sea represented a form of purgatory and the ship a form of hell. In the end, the Africans who made the journey would have survived disease, malnutrition, confined space, close death, and the trauma of the ship.

In Algiers during the time of the Regency of Algiers in North Africa in the 19th century, 1.5 million Christians and Europeans were captured and forced into slavery. This eventually led to the Bombardment of Algiers in 1816 by the British and Dutch, forcing the Dey of Algiers to free many slaves.

The trading of children has been reported in modern Nigeria and Benin. In parts of Ghana, a family may be punished for an offense by having to turn over a virgin female to serve as a sex slave within the offended family. In this instance, the woman does not gain the title or status of "wife". In parts of Ghana, Togo, and Benin, shrine slavery persists, despite being illegal in Ghana since 1998. In this system of ritual servitude, sometimes called trokosi (in Ghana) or voodoosi in Togo and Benin, young virgin girls are given as slaves to traditional shrines and are used sexually by the priests in addition to providing free labor for the shrine.

An article in the Middle East Quarterly in 1999 reported that slavery is endemic in Sudan. Estimates of abductions during the Second Sudanese Civil War range from 14,000 to 200,000 people.

During the Second Sudanese Civil War people were taken into slavery; estimates of abductions range from 14,000 to 200,000. Abduction of Dinka women and children was common. In Mauritania it is estimated that up to 600,000 men, women and children, or 20% of the population, are currently enslaved, many of them used as bonded labor. Slavery in Mauritania was criminalized in August 2007.

During the Darfur conflict that began in 2003, many people were kidnapped by Janjaweed and sold into slavery as agricultural labor, domestic servants and sex slaves.

In Niger, slavery is also a current phenomenon. A Nigerien study has found that more than 800,000 people are enslaved, almost 8% of the population. Niger installed an anti-slavery provision in 2003. In a landmark ruling in 2008, the ECOWAS Community Court of Justice declared that the Republic of Niger failed to protect Hadijatou Mani Koraou from slavery, and awarded Mani CFA 10,000,000 (approximately US$20,000) in reparations.

Sexual slavery and forced labor are common in the Democratic Republic of Congo.

Many pygmies in the Republic of Congo and Democratic Republic of Congo belong from birth to Bantus in a system of slavery.

Evidence emerged in the late 1990s of systematic slavery in cacao plantations in West Africa; see the chocolate and slavery article.

On the night of 14-15 April 2014, a group of militants attacked the Government Girls Secondary School in Chibok, Nigeria. They broke into the school, pretending to be guards, telling the girls to get out and come with them. A large number of students were taken away in trucks, possibly into the Konduga area of the Sambisa Forest where Boko Haram were known to have fortified camps. Houses in Chibok were also burned down in the incident. According to police, approximately 276 children were taken in the attack, of whom 53 had escaped as of 2 May. Other reports said that 329 girls were kidnapped, 53 had escaped and 276 were still missing. The students have been forced to convert to Islam and into marriage with members of Boko Haram, with a reputed " bride price" of ₦2,000 each ($12.50/ £7.50). Many of the students were taken to the neighbouring countries of Chad and Cameroon, with sightings reported of the students crossing borders with the militants, and sightings of the students by villagers living in the Sambisa Forest, which is considered a refuge for Boko Haram.

On 5 May 2014 a video in which Boko Haram leader Abubakar Shekau claimed responsibility for the kidnappings emerged. Shekau claimed that "Allah instructed me to sell them...I will carry out his instructions" and "[s]lavery is allowed in my religion, and I shall capture people and make them slaves." He said the girls should not have been in school and instead should have been married since girls as young as nine are suitable for marriage.

During the Second Libyan Civil War Libyans started capturing some of the Sub-Saharan African migrants trying to get to Europe through Libya and selling them on slave markets. Slaves are often ransomed to their families and in the meantime until ransom can be paid, they may be tortured, forced to work, sometimes worked to death, and eventually they may be executed or left to starve if the payment has not been made after a period of time. Women are often raped and used as sex slaves and sold to brothels.

Many child migrants also suffer from abuse and child rape in Libya.

In Pre-Columbian Mesoamerica the most common forms of slavery were those of prisoners of war and debtors. People unable to pay back debts could be sentenced to work as slaves to the persons owed until the debts were worked off. Warfare was important to Maya society, because raids on surrounding areas provided the victims required for human sacrifice, as well as slaves for the construction of temples. Most victims of human sacrifice were prisoners of war or slaves. Slavery was not usually hereditary; children of slaves were born free. In the Inca Empire, workers were subject to a in lieu of taxes which they paid by working for the government. Each , or extended family, would decide which family member to send to do the work. It is unclear if this labor draft or corvée counts as slavery. The Spanish adopted this system, particularly for their silver mines in Bolivia.

Other slave-owning societies and tribes of the New World were, for example, the Tehuelche of Patagonia, the Comanche of Texas, the Caribs of Dominica, the Tupinambá of Brazil, the fishing societies, such as the Yurok, that lived along the coast from what is now Alaska to California, the Pawnee and Klamath. Many of the indigenous peoples of the Pacific Northwest Coast, such as the Haida and Tlingit, were traditionally known as fierce warriors and slave-traders, raiding as far as California. Slavery was hereditary, the slaves being prisoners of war. Among some Pacific Northwest tribes about a quarter of the population were slaves. One slave narrative was composed by an Englishman, John R. Jewitt, who had been taken alive when his ship was captured in 1802; his memoir provides a detailed look at life as a slave, and asserts that a large number were held.

During the period from the late 19th century and early 20th century, demand for the labor-intensive harvesting of rubber drove frontier expansion and slavery in Latin America and elsewhere. Indigenous peoples were enslaved as part of the rubber boom in Ecuador, Peru, Colombia, and Brazil. In Central America, rubber tappers participated in the enslavement of the indigenous Guatuso-Maleku people for domestic service.

Slavery was a mainstay of the Brazilian colonial economy, especially in mining and sugarcane production. 35.3% of all slaves involved in the Atlantic Slave trade went to Brazil. 4 million slaves were obtained by Brazil, 1.5 million more than any other country. Starting around 1550, the Portuguese began to trade African slaves to work the sugar plantations, once the native Tupi people deteriorated. Although Portuguese Prime Minister Sebastião José de Carvalho e Melo, 1st Marquis of Pombal abolished slavery in mainland Portugal on 12 February 1761, slavery continued in her overseas colonies. Slavery was practiced among all classes. Slaves were owned by upper and middle classes, by the poor, and even by other slaves.

From São Paulo, the Bandeirantes, adventurers mostly of mixed Portuguese and native ancestry, penetrated steadily westward in their search for Indian slaves. Along the Amazon river and its major tributaries, repeated slaving raids and punitive attacks left their mark. One French traveler in the 1740s described hundreds of miles of river banks with no sign of human life and once-thriving villages that were devastated and empty. In some areas of the Amazon Basin, and particularly among the Guarani of southern Brazil and Paraguay, the Jesuits had organized their Jesuit Reductions along military lines to fight the slavers. In the mid-to-late 19th century, many Amerindians were enslaved to work on rubber plantations.

Escaped slaves formed Maroon communities which played an important role in the histories of Brazil and other countries such as Suriname, Puerto Rico, Cuba, and Jamaica. In Brazil, the Maroon villages were called palenques or quilombos. Maroons survived by growing vegetables and hunting. They also raided plantations. At these attacks, the maroons would burn crops, steal livestock and tools, kill slavemasters, and invite other slaves to join their communities.

Jean-Baptiste Debret, a French painter who was active in Brazil in the first decades of the 19th century, started out with painting portraits of members of the Brazilian Imperial family, but soon became concerned with the slavery of both blacks and indigenous inhabitants. His paintings on the subject (two appear on this page) helped bring attention to the subject in both Europe and Brazil itself.

The Clapham Sect, a group of evangelical reformers, campaigned during much of the 19th century for Britain to use its influence and power to stop the traffic of slaves to Brazil. Besides moral qualms, the low cost of slave-produced Brazilian sugar meant that British colonies in the West Indies were unable to match the market prices of Brazilian sugar, and each Briton was consuming 16 pounds (7 kg) of sugar a year by the 19th century. This combination led to intensive pressure from the British government for Brazil to end this practice, which it did by steps over several decades.

Brazil's 1877-78 Grande Seca (Great Drought) in the cotton-growing northeast led to major turmoil, starvation, poverty and internal migration. As wealthy plantation holders rushed to sell their slaves south, popular resistance and resentment grew, inspiring numerous emancipation societies. They succeeded in banning slavery altogether in the province of Ceará by 1884. Slavery was legally ended nationwide on 13 May by the ("Golden Law") of 1888. It was an institution in decadence at these times, as since the 1880s the country had begun to use European immigrant labor instead. Brazil was the last nation in the Western Hemisphere to abolish slavery.

Slavery was commonly used in the parts of the Caribbean controlled by France and the British Empire. The Lesser Antilles islands of Barbados, St. Kitts, Antigua, Martinique and Guadeloupe, which were the first important slave societies of the Caribbean, began the widespread use of African slaves by the end of the 17th century, as their economies converted from sugar production.

England had multiple sugar islands in the Caribbean, especially Jamaica, Barbados, Nevis, and Antigua, which provided a steady flow of sugar sales; slave labor produced the sugar. By the 1700s, there were more slaves in Barbados than all the colonies combined. Since Barbados did not have many mountains, the British were able to clear land for sugar cane. Indentured servants were initially sent to Barbados to work in the sugar fields. These indentured servants were treated so poorly that future indentured servants stopped going to Barbados, and there were not enough people to work the fields. This is when the British started bringing in African slaves. It was important for the slaves to be in Barbados because sugar had become a necessity for most people and the demand for it was high.

An important result of Britain's victory in the War of the Spanish Succession (1702-1714) was enlarging its role in the slave trade. Of special importance was the successful secret negotiation with France to obtain thirty-year monopoly on the Spanish slave trade, called the Queen Anne of Great Britain also allowed her North American colonies like Virginia to make laws that promoted black slavery. Anne had secretly negotiated with France to get its approval regarding the Asiento. She boasted to Parliament of her success in taking the Asiento away from France and London celebrated her economic coup. Most of the slave trade involved sales to Spanish colonies in the Caribbean, and to Mexico, as well as sales to British colonies in the Caribbean and in North America. Historian Vinita Ricks says the agreement allotted Queen Anne "22.5% (and King Philip V, of Spain 28%) of all profits collected for her personal fortune." Ricks concludes that the Queen's "connection to slave trade revenue meant that she was no longer a neutral observer. She had a vested interest in what happened on slave ships."

By 1778, the French were importing approximately 13,000 Africans for enslavement yearly to the French West Indies.

To regularise slavery, in 1685 Louis XIV had enacted the , which accorded certain human rights to slaves and responsibilities to the master, who was obliged to feed, clothe and provide for the general well-being of his slaves. Free blacks owned one-third of the plantation property and one-quarter of the slaves in Saint Domingue (later Haiti). Slavery in the French First Republic was abolished on 4 February 1794. When it became clear that Napoleon intended to re-establish slavery in Haiti, Dessalines and Pétion switched sides, in October 1802. On 1 January 1804, Jean-Jacques Dessalines, the new leader under the dictatorial 1801 constitution, declared Haiti a free republic. Thus Haiti became the second independent nation in the Western Hemisphere, after the United States, and the only successful slave rebellion in world history.

Whitehall in England announced in 1833 that slaves in its territories would be totally freed by 1840. In the meantime, the government told slaves they had to remain on their plantations and would have the status of "apprentices" for the next six years.

In Port-of-Spain, Trinidad, on 1 August 1834, an unarmed group of mainly elderly Negroes being addressed by the Governor at Government House about the new laws, began chanting: "Pas de six ans. Point de six ans" ("Not six years. No six years"), drowning out the voice of the Governor. Peaceful protests continued until a resolution to abolish apprenticeship was passed and de facto freedom was achieved. Full emancipation for all was legally granted ahead of schedule on 1 August 1838, making Trinidad the first British colony with slaves to completely abolish slavery.

In late August 1619, the frigate , a privateer ship owned by Robert Rich, 2nd Earl of Warwick, but flying a Dutch flag arrived at Point Comfort, Virginia (several miles downstream from the colony of Jamestown, Virginia) with the first recorded slaves from Africa to Virginia. The approximately 20 Africans were from the present-day Angola. They had been removed by the White Lion's crew from a Portuguese slave ship, the São João Bautista.

Only a fraction of the enslaved Africans brought to the New World came to British North America, perhaps as little as 5% of the total. The vast majority of slaves were sent to the Caribbean sugar colonies, Brazil, or Spanish America.

By the 1680s, with the consolidation of England's Royal African Company, enslaved Africans were arriving in English colonies in larger numbers, and the institution continued to be protected by the British government. Colonists now began purchasing slaves in larger numbers.

1640: Virginia courts sentence John Punch to lifetime slavery, marking the earliest legal sanctioning of slavery in English colonies.

1641: Massachusetts legalizes slavery.

1650: Connecticut legalizes slavery.

1654: Virginia sanctions "the right of Negros to own slaves of their own race" after African Anthony Johnson, former indentured servant, sued to have fellow African John Casor declared not an indentured servant but "slave for life."

1661: Virginia officially recognizes slavery by statute.

1662: A Virginia statute declares that children born would have the same status as their mother.

1663: Maryland legalizes slavery.

1664: Slavery is legalized in New York and New Jersey.

1670: Carolina (later, South Carolina and North Carolina) is founded mainly by planters from the overpopulated British sugar island colony of Barbados, who brought relatively large numbers of African slaves from that island.

The shift from indentured servants to African slaves was prompted by a dwindling class of former servants who had worked through the terms of their indentures and thus became competitors to their former masters. These newly freed servants were rarely able to support themselves comfortably, and the tobacco industry was increasingly dominated by large planters. This caused domestic unrest culminating in Bacon's Rebellion. Eventually, chattel slavery became the norm in regions dominated by plantations.

Several local slave rebellions took place during the 17th and 18th centuries: Gloucester County, Virginia Revolt (1663); New York Slave Revolt of 1712; Stono Rebellion (1739); and New York Slave Insurrection of 1741.

Within the British Empire, the Massachusetts courts began to follow England when, in 1772, England became the first country in the world to outlaw the slave trade within its borders (see Somerset v Stewart) followed by the Knight v. Wedderburn decision in Scotland in 1778. Between 1764 and 1774, seventeen slaves appeared in Massachusetts courts to sue their owners for freedom. In 1766, John Adams' colleague Benjamin Kent won the first trial in the present-day United States to free a slave (Slew vs. Whipple).

The Republic of Vermont banned slavery in its constitution of 1777 and continued the ban when it entered the United States in 1791. Through the Northwest Ordinance of 1787 under the Congress of the Confederation, slavery was prohibited in the territories north west of the Ohio River. By 1804, abolitionists succeeded in passing legislation that ended legal slavery in every northern state (with slaves above a certain age legally transformed to indentured servants). Congress banned the international importation or export of slaves on 1 January 1808; but not the internal slave trade.

Despite the actions of abolitionists, free blacks were subject to racial segregation in the Northern states. While England did not ban slavery in present-day Canada until 1833, free blacks found refugee and liberty there after the America Revolution and again after the War of 1812. Slavery in Canada was largely ended by judicial court decisions by the early nineteenth century. Refugees from slavery fled the South across the Ohio River to the North via the Underground Railroad. Midwestern state governments asserted States Rights arguments to refuse federal jurisdiction over fugitives. Some juries exercised their right of jury nullification and refused to convict those indicted under the Fugitive Slave Act of 1850.

After the passage of the Kansas-Nebraska Act in 1854, armed conflict broke out in Kansas Territory, where the question of whether it would be admitted to the Union as a slave state or a free state had been left to the inhabitants. The radical abolitionist John Brown was active in the mayhem and killing in " Bleeding Kansas." The true turning point in public opinion is better fixed at the Lecompton Constitution fraud. Pro-slavery elements in Kansas had arrived first from Missouri and quickly organized a territorial government that excluded abolitionists. Through the machinery of the territory and violence, the pro-slavery faction attempted to force an unpopular pro-slavery constitution through the state. This infuriated Northern Democrats, who supported popular sovereignty, and was exacerbated by the Buchanan administration reneging on a promise to submit the constitution to a referendum-which would surely fail. Anti-slavery legislators took office under the banner of the newly formed Republican Party. The Supreme Court in the Dred Scott decision of 1857 asserted that one could take one's property anywhere, even if one's property was chattel and one crossed into a free territory. It also asserted that African Americans could not be federal citizens. Outraged critics across the North denounced these episodes as the latest of the Slave Power (the politically organized slave owners) taking more control of the nation.

The slave population in the United States stood at four million. Ninety-five percent of blacks lived in the South, comprising one third of the population there as opposed to 1% of the population of the North. The central issue in politics in the 1850s involved the extension of slavery into the western territories, which settlers from the Northern states opposed. The Whig Party split and collapsed on the slavery issue, to be replaced in the North by the new Republican Party, which was dedicated to stopping the expansion of slavery. Republicans gained a majority in every northern state by absorbing a faction of anti-slavery Democrats, and warning that slavery was a backward system that undercut democracy and economic modernization. Numerous compromise proposals were put forward, but they all collapsed. A majority of Northern voters were committed to stopping the expansion of slavery, which they believed would ultimately end slavery. Southern voters were overwhelmingly angry that they were being treated as second-class citizens. In the election of 1860, the Republicans swept Abraham Lincoln into the Presidency and his party took control (with only 39.8% of the popular vote) and legislators into Congress. The states of the deep South, convinced that the economic power of what they called " King Cotton" would overwhelm the North and win support from Europe voted to seceded from the U.S. (the Union). They formed the Confederate States of America, based on the promise of maintaining slavery. War broke out in April 1861, as both sides sought wave after wave of enthusiasm among young men volunteering to form new regiments and new armies. In the North, the main goal was to preserve the union as an expression of American nationalism.

By 1862 most northern leaders realized that the mainstay of Southern secession, slavery, had to be attacked head-on. All the border states rejected President Lincoln's proposal for compensated emancipation. However, by 1865 all had begun the abolition of slavery, except Kentucky and Delaware. The Emancipation Proclamation was an executive order issued by Lincoln on 1 January 1863. In a single stroke, it changed the legal status, as recognized by the U.S. government, of 3 million slaves in designated areas of the Confederacy from "slave" to "free." It had the practical effect that as soon as a slave escaped the control of the Confederate government, by running away or through advances of federal troops, the slave became legally and actually free. Plantation owners, realizing that emancipation would destroy their economic system, sometimes moved their slaves as far as possible out of reach of the Union army. By June 1865, the Union Army controlled all of the Confederacy and liberated all of the designated slaves. The owners were never compensated. Over 200,000 free blacks and newly freed slaves fought for the Union in the Army and Navy, thereby validating their claims to full citizenship.

The severe dislocations of war and Reconstruction had a severe negative impact on the black population, with a large amount of sickness and death. After liberation, many of the Freedmen remained on the same plantation. Others fled or crowded into refugee camps operated by the Freedmen's Bureau. The Bureau provided food, housing, clothing, medical care, church services, some schooling, legal support, and arranged for labor contracts. Fierce debates about the rights of the Freedmen, and of the defeated Confederates, often accompanied by killings of black leaders, marked the Reconstruction Era, 1863-77.

Slavery was never reestablished, but after 1877, white Democrats took control of all the southern states and blacks lost nearly all the political power they had achieved during Reconstruction. By 1900 they also lost the right to vote. They had become second class citizens. The great majority lived in the rural South in poverty working as laborers, sharecroppers or tenant farmers; a small proportion owned their own land. The black churches, especially the Baptist Church, was the center of community activity and leadership.

Slavery in the Middle East first developed out of the slavery practices of the Ancient Near East, and these practices were radically different at times, depending on social-political factors such as the Arab slave trade. Two rough estimates by scholars of the number of slaves held over twelve centuries in Muslim lands are 11.5 million and 14 million.

Under Sharia (Islamic law), children of slaves or prisoners of war could become slaves but only non-Muslims. Manumission of a slave was encouraged as a way of expiating sins. Many early converts to Islam, such as Bilal ibn Rabah al-Habashi, were the poor and former slaves. In theory, slavery in Islamic law does not have a racial or color component, although this has not always been the case in practice.

Bernard Lewis writes: "In one of the sad paradoxes of human history, it was the humanitarian reforms brought by Islam that resulted in a vast development of the slave trade inside, and still more outside, the Islamic empire." He notes that the Islamic injunctions against the enslavement of Muslims led to massive importation of slaves from the outside. According to Patrick Manning, Islam by recognizing and codifying the slavery seems to have done more to protect and expand slavery than the reverse.

Slavery was a legal and important part of the economy of the Ottoman Empire and Ottoman society until the slavery of Caucasians was banned in the early 19th century, although slaves from other groups were allowed. In Constantinople (present-day Istanbul), the administrative and political center of the Empire, about a fifth of the population consisted of slaves in 1609. Even after several measures to ban slavery in the late 19th century, the practice continued largely unfazed into the early 20th century. As late as 1908, female slaves were still sold in the Ottoman Empire. Sexual slavery was a central part of the Ottoman slave system throughout the history of the institution.

A member of the Ottoman slave class, called a in Turkish, could achieve high status. Harem guards and janissaries are some of the better-known positions a slave could hold, but slaves were actually often at the forefront of Ottoman politics. The majority of officials in the Ottoman government were bought slaves, raised free, and integral to the success of the Ottoman Empire from the 14th century into the 19th. Many officials themselves owned a large number of slaves, although the Sultan himself owned by far the largest amount. By raising and specially training slaves as officials in palace schools such as Enderun, the Ottomans created administrators with intricate knowledge of government and fanatic loyalty.

Ottomans practiced , a sort of "blood tax" or "child collection", young Christian boys from the Balkans and Anatolia were taken from their homes and families, brought up as Muslims, and enlisted into the most famous branch of the , the Janissaries, a special soldier class of the Ottoman army that became a decisive faction in the Ottoman invasions of Europe.

During the various 18th and 19th century persecution campaigns against Christians as well as during the culminating Assyrian, Armenian and Greek genocides of World War I, many indigenous Armenian, Assyrian and Greek Christian women and children were carried off as slaves by the Ottoman Turks and their Kurdish allies. Henry Morgenthau, Sr., U.S. Ambassador in Constantinople from 1913 to 1916, reports in his Ambassador Morgenthau's Story that there were gangs trading white slaves during his term in Constantinople. He also reports that Armenian girls were sold as slaves during the Armenian Genocide.

The Arab or Islamic slave trade lasted much longer than the Atlantic or European slave trade: "It began in the middle of the seventh century and survives today in Mauritania and Sudan. With the Islamic slave trade, we're talking of 14 centuries rather than four." Further, "whereas the gender ratio of slaves in the Atlantic trade was two males to every female, in the Islamic trade, it was two females to every male," according to Ronald Segal

According to media reports from late 2014 the Islamic State of Iraq and the Levant (ISIL) was selling Yazidi and Christian women as slaves. According to Haleh Esfandiari of the Woodrow Wilson International Center for Scholars, after ISIL militants have captured an area "[t]hey usually take the older women to a makeshift slave market and try to sell them." In mid-October 2014, the UN estimated that 5,000 to 7,000 Yazidi women and children were abducted by ISIL and sold into slavery. In the digital magazine , ISIL claimed religious justification for enslaving Yazidi women whom they consider to be from a heretical sect. ISIL claimed that the Yazidi are idol worshipers and their enslavement is part of the old shariah practice of spoils of war. According to The Wall Street Journal, ISIL appeals to apocalyptic beliefs and claims "justification by a Hadith that they interpret as portraying the revival of slavery as a precursor to the end of the world".

ISIL announced the revival of slavery as an institution. In 2015 the official slave prices set by ISIL were following:

Children aged 1 to 9 were sold for 200,000 dinars ($169).

Women and children 10 to 20 years old for 150,000 dinars ($127).

Women 20 to 30 years old for 100,000 dinar ($85).

Women 30 to 40 years old are 75,000 dinar ($63).

Women 40 to 50 years old for 50,000 dinar ($42).

However some slaves have been sold for as little as a pack of cigarettes. Sex slaves were sold to Saudi Arabia, other Persian Gulf states and Turkey.

Slavery has existed all throughout Asia, and forms of slavery still exist today.

Scholars differ as to whether or not slaves and the institution of slavery existed in ancient India. These English words have no direct, universally accepted equivalent in Sanskrit or other Indian languages, but some scholars translate the word , mentioned in texts like Manu Smriti, as slaves. Ancient historians who visited India offer the closest insights into the nature of Indian society and slavery in other ancient civilizations. For example, the Greek historian Arrian, who chronicled India about the time of Alexander the Great, wrote in his Indika,

The Indians do not even use aliens as slaves, much less a countryman of their own.

Qin dynasty (221-206 BC) Men sentenced to castration became eunuch slaves of the Qin dynasty state and as a result they were made to do forced labor, on projects like the Terracotta Army. The Qin government confiscated the property and enslaved the families of those who received castration as a punishment for rape.
Slaves were deprived of their rights and connections to their families.

Han dynasty (206 BC - 220 AD) One of Emperor Gao's first acts was to set free from slavery agricultural workers who were enslaved during the Warring States period, although domestic servants retained their status.

Men punished with castration during the Han dynasty were also used as slave labor.

Deriving from earlier Legalist laws, the Han dynasty set in place rules that the property of and families of criminals doing three years of hard labor or sentenced to castration were to have their families seized and kept as property by the government.

During the millennium long Chinese domination of Vietnam, Vietnam was a great source of slave girls who were used as sex slaves in China. The slave girls of Viet were even eroticized in Tang dynasty poetry.

The Islamic invasions, starting in the 8th century, also resulted in hundreds of thousands of Indians being enslaved by the invading armies, one of the earliest being the armies of the Umayyad commander Muhammad bin Qasim. Qutb-ud-din Aybak, a Turkic slave of Muhammad Ghori rose to power following his master's death. For almost a century, his descendants ruled North-Central India in form of Slave Dynasty. Several slaves were also brought to India by the Indian Ocean trades; for example, the Siddi are descendants of Bantu slaves brought to India by Arab and Portuguese merchants.

Andre Wink summarizes the slavery in 8th and 9th century India as follows,

(During the invasion of Muhammad al-Qasim), invariably numerous women and children were enslaved. The sources insist that now, in dutiful conformity to religious law, 'the one-fifth of the slaves and spoils' were set apart for the caliph's treasury and despatched to Iraq and Syria. The remainder was scattered among the army of Islam. At Rūr, a random 60,000 captives reduced to slavery. At Brahamanabad 30,000 slaves were allegedly taken. At Multan 6,000. Slave raids continued to be made throughout the late Umayyad period in Sindh, but also much further into Hind, as far as Ujjain and Malwa. The Abbasid governors raided Punjab, where many prisoners and slaves were taken.

In the early 11th century Tarikh al-Yamini, the Arab historian Al-Utbi recorded that in 1001 the armies of Mahmud of Ghazna conquered Peshawar and Waihand (capital of Gandhara) after Battle of Peshawar (1001), "in the midst of the land of Hindustan", and captured some 100,000 youths. Later, following his twelfth expedition into India in 1018-19, Mahmud is reported to have returned with such a large number of slaves that their value was reduced to only two to ten dirhams each. This unusually low price made, according to Al-Utbi, "merchants [come] from distant cities to purchase them, so that the countries of Central Asia, Iraq and Khurasan were swelled with them, and the fair and the dark, the rich and the poor, mingled in one common slavery". Elliot and Dowson refer to "five hundred thousand slaves, beautiful men and women.". Later, during the Delhi Sultanate period (1206-1555), references to the abundant availability of low-priced Indian slaves abound. Levi attributes this primarily to the vast human resources of India, compared to its neighbors to the north and west (India's Mughal population being approximately 12 to 20 times that of Turan and Iran at the end of the 16th century).

Slavery and empire-formation tied in particularly well with iqta and it is within this context of Islamic expansion that elite slavery was later commonly found. It became the predominant system in North India in the thirteenth century and retained considerable importance in the fourteenth century. Slavery was still vigorous in fifteenth-century Bengal, while after that date it shifted to the Deccan where it persisted until the seventeenth century. It remained present to a minor extent in the Mughal provinces throughout the seventeenth century and had a notable revival under the Afghans in North India again in the eighteenth century.

The Delhi sultanate obtained thousands of slaves and eunuch servants from the villages of Eastern Bengal (a widespread practice which Mughal emperor Jahangir later tried to stop). Wars, famines, pestilences drove many villagers to sell their children as slaves. The Muslim conquest of Gujarat in Western India had two main objectives. The conquerors demanded and more often forcibly wrested both land owned by Hindus and Hindu women. Enslavement of women invariably led to their conversion to Islam. In battles waged by Muslims against Hindus in Malwa and Deccan plateau, a large number of captives were taken. Muslim soldiers were permitted to retain and enslave POWs as plunder.

The first Bahmani sultan, Alauddin Bahman Shah is noted to have captured 1,000 singing and dancing girls from Hindu temples after he battled the northern Carnatic chieftains. The later Bahmanis also enslaved civilian women and children in wars; many of them were converted to Islam in captivity. About the Mughal empire, W.H. Moreland observed, "it became a fashion to raid a village or group of villages without any obvious justification, and carry off the inhabitants as slaves."

During the rule of Shah Jahan, many peasants were compelled to sell their women and children into slavery to meet the land revenue demand. Slavery was officially abolished in British India by the Indian Slavery Act, 1843. However, in modern India, Pakistan and Nepal, there are millions of bonded laborers, who work as slaves to pay off debts.

The Tang dynasty purchased Western slaves from the Radanite Jews. Tang Chinese soldiers and pirates enslaved Koreans, Turks, Persians, Indonesians, and people from Inner Mongolia, Central Asia, and northern India. The greatest source of slaves came from southern tribes, including Thais and aboriginals from the southern provinces of Fujian, Guangdong, Guangxi, and Guizhou. Malays, Khmers, Indians, and black Africans were also purchased as slaves in the Tang dynasty. Slavery was prevalent until the late 19th century and early 20th century China. All forms of slavery have been illegal in China since 1910.

Slavery in Japan was, for most of its history, indigenous, since the export and import of slaves was restricted by Japan being a group of islands. In late-16th-century Japan, slavery was officially banned; but forms of contract and indentured labor persisted alongside the period penal codes' forced labor. During the Second Sino-Japanese War and the Pacific War, the Japanese military used millions of civilians and prisoners of war from several countries as forced laborers.

In Korea, slavery was officially abolished with the Gabo Reform of 1894. During the Joseon period, in times of poor harvest and famine, many peasants voluntarily sold themselves into the nobi system in order to survive.

In Southeast Asia, there was a large slave class in Khmer Empire who built the enduring monuments in Angkor Wat and did most of the heavy work. Between the 17th and the early 20th centuries one-quarter to one-third of the population of some areas of Thailand and Burma were slaves. By the 19th century, Bhutan had developed a slave trade with Sikkim and Tibet, also enslaving British subjects and Brahmins. According to the International Labour Organization (ILO), during the early 21st century an estimated 800,000 people are subject to forced labor in Myanmar.

Slavery in pre-Spanish Philippines was practiced by the tribal Austronesian peoples who inhabited the culturally diverse islands. The neighbouring Muslim states conducted slave raids from the 1600s into the 1800s in coastal areas of the Gulf of Thailand and the Philippine islands. Slaves in Toraja society in Indonesia were family property. People would become slaves when they incurred a debt. Slaves could also be taken during wars, and slave trading was common. Torajan slaves were sold and shipped out to Java and Siam. Slaves could buy their freedom, but their children still inherited slave status. Slavery was abolished in 1863 in all Dutch colonies.

Records of slavery in Ancient Greece go as far back as Mycenaean Greece. The origins are not known, but it appears that slavery became an important part of the economy and society only after the establishment of cities. Slavery was common practice and an integral component of ancient Greece, as it was in other societies of the time, including ancient Israel. It is estimated that in Athens, the majority of citizens owned at least one slave. Most ancient writers considered slavery not only natural but necessary, but some isolated debate began to appear, notably in Socratic dialogues. The Stoics produced the first condemnation of slavery recorded in history.

During the 8th and the 7th centuries BC, in the course of the two Messenian Wars, the Spartans reduced an entire population to a pseudo-slavery called . According to Herodotus (IX, 28-29), helots were seven times as numerous as Spartans. Following several helot revolts around the year 600 BC, the Spartans restructured their city-state along authoritarian lines, for the leaders decided that only by turning their society into an armed camp could they hope to maintain control over the numerically dominant helot population. In some Ancient Greek city-states, about 30% of the population consisted of slaves, but paid and slave labor seem to have been equally important.

Romans inherited the institution of slavery from the Greeks and the Phoenicians. As the Roman Republic expanded outward, it enslaved entire populations, thus ensuring an ample supply of laborers to work in Rome's farms, quarries and households. The people subjected to Roman slavery came from all over Europe and the Mediterranean. Such oppression by an elite minority eventually led to slave revolts; the Third Servile War led by Spartacus was the most famous and severe. Greeks, Berbers, Germans, Britons, Slavs, Thracians, Gauls (or Celts), Jews, Arabs and many more ethnic groups were enslaved to be used for labor, and also for amusement (e.g. gladiators and sex slaves). If a slave ran away, they were liable to be crucified.

The overall impact of slavery on the Italian genetics was insignificant though, because the slaves imported in Italy were native Europeans, and very few if any of them had extra European origin. This has been further confirmed by recent biochemical analysis of 166 skeletons from three non-elite imperial-era cemeteries in the vicinity of Rome (where the bulk of the slaves lived), which shows that only 1 individual definitely came from outside of Europe (North Africa), and another 2 possibly did, but results are inconclusive. In the rest of the Italian peninsula, the amount of non European slaves was definitively much lower than that.

The chaos of invasion and frequent warfare also resulted in victorious parties taking slaves throughout Europe in the early Middle Ages. St. Patrick, himself captured and sold as a slave, protested against an attack that enslaved newly baptized Christians in his "Letter to the Soldiers of Coroticus". As a commonly traded commodity, like cattle, slaves could become a form of internal or trans-border currency. Slavery during the Early Middle Ages had several distinct sources.

The Vikings raided across Europe, but took the most slaves in raids on the British Isles and in Eastern Europe. While the Vikings kept some slaves as servants, known as , they sold most captives in the Byzantine or Islamic markets. In the West, their target populations were primarily English, Irish, and Scottish, while in the East they were mainly Slavs. The Viking slave-trade slowly ended in the 11th century, as the Vikings settled in the European territories they had once raided. They converted serfs to Christianity and themselves merged with the local populace.

In central Europe, specifically the Frankish/German/Holy Roman Empire of Charlemagne, raids and wars to the east generated a steady supply of slaves from the Slavic captives of these regions. Because of high demand for slaves in the wealthy Muslim empires of Northern Africa, Spain, and the Near East, especially for slaves of European descent, a market for these slaves rapidly emerged. So lucrative was this market that it spawned an economic boom in central and western Europe, today known as the Carolingian Renaissance. This boom period for slaves stretched from the early Muslim conquests to the High Middle Ages but declined in the later Middle Ages as the Islamic Golden Age waned.

Medieval Spain and Portugal saw almost constant warfare between Muslims and Christians. Al-Andalus sent periodic raiding expeditions to loot the Iberian Christian kingdoms, bringing back booty and slaves. In a raid against Lisbon, Portugal in 1189, for example, the Almohad caliph Yaqub al-Mansur took 3,000 female and child captives. In a subsequent attack upon Silves, Portugal in 1191, his governor of Córdoba took 3,000 Christian slaves.

The Byzantine-Ottoman wars and the Ottoman wars in Europe resulted in the taking of large numbers of Christian slaves and using or selling them in the Islamic world too. After the battle of Lepanto the victors freed approximately 12,000 Christian galley slaves from the Ottoman fleet.

Similarly, Christians sold Muslim slaves captured in war. The Order of the Knights of Malta attacked pirates and Muslim shipping, and their base became a centre for slave trading, selling captured North Africans and Turks. Malta remained a slave market until well into the late 18th century. One thousand slaves were required to man the galleys (ships) of the Order.

Poland banned slavery in the 15th century; in Lithuania, slavery was formally abolished in 1588; the institution was replaced by the second enserfment. Slavery remained a minor institution in Russia until 1723, when Peter the Great converted the household slaves into house serfs. Russian agricultural slaves were formally converted into serfs earlier, in 1679. The escaped Russian serfs and kholops formed autonomous communities in the southern steppes, where they became known as Cossacks (meaning "outlaws").

Capture in war, voluntary servitude and debt slavery became common within the British Isles before 1066. Slaves were routinely bought and sold. Running away was also common and slavery was never a major economic factor in the British Isles during the Middle Ages. Ireland and Denmark provided markets for captured Anglo-Saxon and Celtic slaves. Pope Gregory I reputedly made the pun, Non Angli, sed Angeli ("Not Angles, but Angels"), after a response to his query regarding the identity of a group of fair-haired Angles, slave children whom he had observed in the marketplace. After the Norman Conquest, the law no longer supported chattel slavery and slaves became part of the larger body of serfs.

Barbary pirates and Maltese corsairs both raided for slaves and purchased slaves from European merchants, often the Radhanites, one of the few groups who could easily move between the Christian and Islamic worlds.

In the late Middle Ages, from 1100 to 1500, the European slave-trade continued, though with a shift from being centered among the Western Mediterranean Islamic nations to the Eastern Christian and Muslim states. The city-states of Venice and Genoa controlled the Eastern Mediterranean from the 12th century and the Black Sea from the 13th century. They sold both Slavic and Baltic slaves, as well as Georgians, Turks, and other ethnic groups of the Black Sea and Caucasus. The sale of European slaves by Europeans slowly ended as the Slavic and Baltic ethnic groups Christianized by the Late Middle Ages. European slaves did not pass on an inherited status and was thus more akin to forced labor, or indentured servitude.

From the 1440s into the 18th century, Europeans from Italy, Spain, Portugal, France, and England were sold into slavery by North Africans, as described in the book "Christian Slaves, Muslim Masters". This same book states that "white slavery had been minimised or ignored because academics preferred to treat Europeans as evil colonialists rather than as victims." and likely overestimates the number of slaves taken. In 1575, the Tatars captured over 35,000 Ukrainians; a 1676 raid took almost 40,000. About 60,000 Ukrainians were captured in 1688; some were ransomed, but most were sold into slavery. Some of the Roma people were enslaved over five centuries in Romania until abolition in 1864 (see Slavery in Romania).

The Mongol invasions and conquests in the 13th century also resulted in taking numerous captives into slavery. The Mongols enslaved skilled individuals, women and children and marched them to Karakorum or Sarai, whence they were sold throughout Eurasia. Many of these slaves were shipped to the slave market in Novgorod.

Slave commerce during the Late Middle Ages was mainly in the hands of Venetian and Genoese merchants and cartels, who were involved in the slave trade with the Golden Horde. In 1382 the Golden Horde under Khan Tokhtamysh sacked Moscow, burning the city and carrying off thousands of inhabitants as slaves. Between 1414 and 1423, some 10,000 eastern European slaves were sold in Venice. Genoese merchants organized the slave trade from the Crimea to Mamluk Egypt. For years, the Khanates of Kazan and Astrakhan routinely made raids on Russian principalities for slaves and to plunder towns. Russian chronicles record about 40 raids by Kazan Khans on the Russian territories in the first half of the 16th century.

In 1441 Haci I Giray declared independence from the Golden Horde and established the Crimean Khanate. For a long time, until the early 18th century, the khanate maintained an extensive slave-trade with the Ottoman Empire and the Middle East. In a process called the "harvesting of the steppe" they enslaved many Slavic peasants. About 30 major Tatar raids were recorded into Muscovite territories between 1558 and 1596.

Moscow was repeatedly a target. In 1521, the combined forces of Crimean Khan Mehmed Giray and his Kazan allies attacked the city and captured thousands of slaves. In 1571, the Crimean Tatars attacked and sacked Moscow, burning everything but the Kremlin and taking thousands of captives as slaves. In Crimea, about 75% of the population consisted of slaves.

In the Viking era beginning circa 793, the Norse raiders often captured and enslaved militarily weaker peoples they encountered. The Nordic countries called their slaves ( Old Norse: Þræll). The thralls were mostly from Western Europe, among them many Franks, Frisians, Anglo-Saxons, and both Irish and Britonnic Celts. Many Irish slaves travelled in expeditions for the colonization of Iceland. The Norse also took German, Baltic, Slavic and Latin slaves. The slave trade was one of the pillars of Norse commerce during the 6th through 11th centuries. The 10th-century Persian traveller Ibn Rustah described how Swedish Vikings, the Varangians or Rus, terrorized and enslaved the Slavs taken in their raids along the Volga River. The thrall system was finally abolished in the mid-14th century in Scandinavia.

Mediterranean powers frequently sentenced convicted criminals to row in the war- galleys of the state (initially only in time of war). After the revocation of the Edict of Nantes in 1685 and Camisard rebellion, the French Crown filled its galleys with French Huguenots, Protestants condemned for resisting the state. Galley-slaves lived and worked in such harsh conditions that many did not survive their terms of sentence, even if they survived shipwreck and slaughter or torture at the hands of enemies or of pirates. Naval forces often turned 'infidel' prisoners-of-war into galley-slaves. Several well-known historical figures served time as galley slaves after being captured by the enemy-the Ottoman corsair and admiral Turgut Reis and the Knights Hospitaller Grand Master Jean Parisot de la Valette among them.

Denmark-Norway was the first European country to ban the slave trade. This happened with a decree issued by King Christian VII of Denmark in 1792, to become fully effective by 1803. Slavery as an institution was not banned until 1848. At this time Iceland was a part of Denmark-Norway but slave trading had been abolished in Iceland in 1117 and had never been reestablished.

Slavery in the French Republic was abolished on 4 February 1794, including in its colonies. The lengthy Haitian Revolution by its slaves and free people of color established Haiti as a free republic in 1804 ruled by blacks, the first of its kind. At the time of the revolution, Haiti was known as Saint-Domingue and was a colony of France. Napoleon Bonaparte gave up on Haiti in 1803, but re-established slavery in Guadeloupe and Martinique in 1804, at the request of planters of the Caribbean colonies. Slavery was permanently abolished in the French empire during the French Revolution of 1848.

The 15th-century Portuguese exploration of the African coast is commonly regarded as the harbinger of European colonialism. In 1452, Pope Nicholas V issued the papal bull Dum Diversas, granting Afonso V of Portugal the right to reduce any "Saracens, pagans and any other unbelievers" to hereditary slavery which legitimized slave trade under Catholic beliefs of that time. This approval of slavery was reaffirmed and extended in his Romanus Pontifex bull of 1455. These papal bulls came to serve as a justification for the subsequent era of the slave trade and European colonialism. Although for a short period as in 1462, Pius II declared slavery to be "a great crime". The followers of the church of England and Protestants did not use the papal bull as a justification. The position of the church was to condemn the slavery of Christians, but slavery was regarded as an old established and necessary institution which supplied Europe with the necessary workforce. In the 16th century, African slaves had replaced almost all other ethnicities and religious enslaved groups in Europe. Within the Portuguese territory of Brazil, and even beyond its original borders, the enslavement of Native Americans was carried out by the Bandeirantes.

Among many other European slave markets, Genoa, and Venice were some well-known markets, their importance and demand growing after the great plague of the 14th century which decimated much of the European workforce. The maritime town of Lagos, Portugal, was the first slave market created in Portugal for the sale of imported African slaves, the Mercado de Escravos, which opened in 1444. In 1441, the first slaves were brought to Portugal from northern Mauritania. Prince Henry the Navigator, major sponsor of the Portuguese African expeditions, as of any other merchandise, taxed one fifth of the selling price of the slaves imported to Portugal. By the year 1552 African slaves made up 10 percent of the population of Lisbon. In the second half of the 16th century, the Crown gave up the monopoly on slave trade and the focus of European trade in African slaves shifted from import to Europe to slave transports directly to tropical colonies in the Americas-in the case of Portugal, especially Brazil. In the 15th century, one-third of the slaves were resold to the African market in exchange of gold. Slavery was abolished in mainland Portugal and Portuguese India in 1761. It was finally abolished in all Portuguese colonies in 1869.

The Spaniards were the first Europeans to use African slaves in the New World on islands such as Cuba and Hispaniola, due to a shortage of labor caused by the spread of diseases, and so the Spanish colonists gradually became involved in the Atlantic slave trade. The first African slaves arrived in Hispaniola in 1501; by 1517, the natives had been "virtually annihilated" mostly to diseases. The problem of the justness of Native American's slavery was a key issue for the Spanish Crown. It was Charles V who gave a definite answer to this complicated and delicate matter. To that end, on 25 November 1542, the Emperor abolished slavery by decree in his Leyes Nuevas New Laws. This bill was based on the arguments given by the best Spanish theologists and jurists who were unanimous in the condemnation of such slavery as unjust; they declared it illegitimate and outlawed it from America-not just the slavery of Spaniards over Natives-but also the type of slavery practiced among the Natives themselves Thus, Spain became the first country to officially abolish slavery.

However, in the Spanish colonies of Cuba and Puerto Rico, where sugarcane production was highly profitable based on slave labor, African slavery persisted until 1873 in Puerto Rico "with provisions for periods of apprenticeship", and 1886 in Cuba.

Although slavery was illegal inside the Netherlands it flourished throughout the Dutch Empire in the Americas, Africa, Ceylon and Indonesia. The Dutch Slave Coast ( Dutch: Slavenkust) referred to the trading posts of the Dutch West India Company on the Slave Coast, which lie in contemporary Ghana, Benin, Togo and Nigeria. Initially the Dutch shipped slaves to northern Brazil, and during the second half of the 17th century they had a controlling interest in the trade to the Spanish colonies. Today's Suriname and Guyana became prominent markets in the 18th century. Between 1612 and 1872, the Dutch operated from some 10 fortresses along the Gold Coast (now Ghana), from which slaves were shipped across the Atlantic. Dutch involvement on the Slave Coast increased with the establishment of a trading post in Offra in 1660. Willem Bosman writes in his Nauwkeurige beschrijving van de Guinese Goud- Tand- en Slavekust (1703) that Allada was also called Grand Ardra, being the larger cousin of Little Ardra, also known as Offra. From 1660 onward, Dutch presence in Allada and especially Offra became more permanent. A report from this year asserts Dutch trading posts, apart from Allada and Offra, in Benin City, Grand-Popo, and Savi.

The Offra trading post soon became the most important Dutch office on the Slave Coast. According to a 1670 report, annually 2,500 to 3,000 slaves were transported from Offra to the Americas. These numbers were only feasible in times of peace, however, and dwindled in time of conflict. From 1688 onward, the struggle between the Aja king of Allada and the peoples on the coastal regions, impeded the supply of slaves. The Dutch West India Company chose the side of the Aja king, causing the Offra office to be destroyed by opposing forces in 1692. By 1650 the Dutch had the pre-eminent slave trade in Europe and South East Asia. Later, trade shifted to Ouidah. On the instigation of Governor-General of the Dutch Gold Coast Willem de la Palma, Jacob van den Broucke was sent in 1703 as "opperkommies" (head merchant) to the Dutch trading post at Ouidah, which according to sources was established around 1670. Political unrest caused the Dutch to abandon their trading post at Ouidah in 1725, and they then moved to Jaquim, at which place they built Fort Zeelandia. The head of the post, Hendrik Hertog, had a reputation for being a successful slave trader. In an attempt to extend his trading area, Hertog negotiated with local tribes and mingled in local political struggles. He sided with the wrong party, however, leading to a conflict with Director-General Jan Pranger and to his exile to the island of Appa in 1732. The Dutch trading post on this island was extended as the new centre of the slave trade. In 1733, Hertog returned to Jaquim, this time extending the trading post into Fort Zeelandia. The revival of the slave trade at Jaquim was only temporary, however, as his superiors at the Dutch West India Company noticed that Hertog's slaves were more expensive than at the Gold Coast. From 1735, Elmina became the preferred spot to trade slaves. As of 1778, it was estimated that the Dutch were shipping approximately 6,000 Africans for enslavement in the Dutch West Indies each year. Slavery also characterised the Dutch possessions in Indonesia, Ceylon and South Africa, where Indonesians have made a significant contribution to the Cape Coloured population of that country. The Dutch part in the Atlantic slave trade is estimated at 5-7 percent, as they shipped about 550,000-600,000 African slaves across the Atlantic, about 75,000 of whom died on board before reaching their destinations. From 1596 to 1829, the Dutch traders sold 250,000 slaves in the Dutch Guianas, 142,000 in the Dutch Caribbean islands, and 28,000 in Dutch Brazil. In addition, tens of thousands of slaves, mostly from India and some from Africa, were carried to the Dutch East Indies. The Netherlands was one of the last countries to abolish slavery in 1863. Although the decision was made in 1848, it took many years for the law to be implemented. Furthermore, slaves in Suriname would be fully free only in 1873, since the law stipulated that there was to be a mandatory 10-year transition.

Barbary Corsairs continued to trade in European slaves into the Modern time-period. Muslim pirates, primarily Algerians with the support of the Ottoman Empire, raided European coasts and shipping from the 16th to the 19th centuries, and took thousands of captives, whom they sold or enslaved. Many were held for ransom, and European communities raised funds such as Malta's Monte della Redenzione degli Schiavi to buy back their citizens. The raids gradually ended with the naval decline of the Ottoman Empire in the late 16th and 17th centuries, as well as the European conquest of North Africa throughout the 19th century.

From 1609 to 1616, England lost 466 merchant ships to Barbary pirates. 160 English ships were captured by Algerians between 1677 and 1680. Many of the captured sailors were made into slaves and held for ransom. The corsairs were no strangers to the South West of England where raids were known in a number of coastal communities. In 1627 Barbary Pirates under command of the Dutch renegade Jan Janszoon (Murat Reis), operating from the Moroccan port of Salé, occupied the island of Lundy. During this time there were reports of captured slaves being sent to Algiers.

Ireland, despite its northern position, was not immune from attacks by the corsairs. In June 1631 Janszoon, with pirates from Algiers and armed troops of the Ottoman Empire, stormed ashore at the little harbor village of Baltimore, County Cork. They captured almost all the villagers and took them away to a life of slavery in North Africa. The prisoners were destined for a variety of fates-some lived out their days chained to the oars as galley slaves, while others would spend long years in the scented seclusion of the harem or within the walls of the sultan's palace. Only two of them ever saw Ireland again.

The Congress of Vienna (1814-15), which ended the Napoleonic Wars, led to increased European consensus on the need to end Barbary raiding. The sacking of Palma on the island of Sardinia by a Tunisian squadron, which carried off 158 inhabitants, roused widespread indignation. Britain had by this time banned the slave trade and was seeking to induce other countries to do likewise. States that were more vulnerable to the corsairs complained that Britain cared more for ending the trade in African slaves than stopping the enslavement of Europeans and Americans by the Barbary States.

In order to neutralise this objection and further the anti-slavery campaign, in 1816 Britain sent Lord Exmouth to secure new concessions from Tripoli, Tunis, and Algiers, including a pledge to treat Christian captives in any future conflict as prisoners of war rather than slaves. He imposed peace between Algiers and the kingdoms of Sardinia and Sicily. On his first visit, Lord Exmouth negotiated satisfactory treaties and sailed for home. While he was negotiating, a number of Sardinian fishermen who had settled at Bona on the Tunisian coast were brutally treated without his knowledge. As Sardinians they were technically under British protection, and the government sent Exmouth back to secure reparation. On 17 August, in combination with a Dutch squadron under Admiral Van de Capellen, Exmouth bombarded Algiers. Both Algiers and Tunis made fresh concessions as a result.

The Barbary states had difficulty securing uniform compliance with a total prohibition of slave-raiding, as this had been traditionally of central importance to the North African economy. Slavers continued to take captives by preying on less well-protected peoples. Algiers subsequently renewed its slave-raiding, though on a smaller scale. Europeans at the Congress of Aix-la-Chapelle in 1818 discussed possible retaliation. In 1820 a British fleet under Admiral Sir Harry Neal bombarded Algiers. Corsair activity based in Algiers did not entirely cease until France conquered the state in 1830.

The Crimeans frequently mounted raids into the Danubian principalities, Poland-Lithuania, and Muscovy to enslave people whom they could capture; for each captive, the khan received a fixed share (savğa) of 10% or 20%. These campaigns by Crimean forces were either sefers ("sojourns" - officially declared military operations led by the khans themselves), or çapuls ("despoiling" - raids undertaken by groups of noblemen, sometimes illegally because they contravened treaties concluded by the khans with neighbouring rulers).

For a long time, until the early 18th century, the Crimean Khanate maintained a massive slave trade with the Ottoman Empire and the Middle East, exporting about 2 million slaves from Russia and Poland-Lithuania over the period 1500-1700. Caffa (modern Feodosia) became one of the best-known and significant trading ports and slave markets. In 1769 the last major Tatar raid saw the capture of 20,000 Russian and Ruthenian slaves.

Author and historian Brian Glyn Williams writes:

Fisher estimates that in the sixteenth century the Polish-Lithuanian Commonwealth lost around 20,000 individuals a year and that from 1474 to 1694, as many as a million Commonwealth citizens were carried off into Crimean slavery.

Early modern sources are full of descriptions of sufferings of Christian slaves captured by the Crimean Tatars in the course of their raids:

It seems that the position and everyday conditions of a slave depended largely on his/her owner. Some slaves indeed could spend the rest of their days doing exhausting labor: as the Crimean vizir (minister) Sefer Gazi Aga mentions in one of his letters, the slaves were often "a plough and a scythe" of their owners. Most terrible, perhaps, was the fate of those who became galley-slaves, whose sufferings were poeticized in many Ukrainian dumas (songs). ... Both female and male slaves were often used for sexual purposes.

Britain played a prominent role in the Atlantic slave trade, especially after 1640, when sugar cane was introduced to the region. At first, most were white Britons, or Irish, enslaved as indentured labour - for a fixed period - in the West Indies. These people may have been criminals, political rebels, the poor with no prospects or others who were simply tricked or kidnapped. Slavery was a legal institution in all of the 13 American colonies and Canada (acquired by Britain in 1763). The profits of the slave trade and of West Indian plantations amounted to 5% of the British economy at the time of the Industrial Revolution.

A little-known incident in the career of Judge Jeffreys refers to an assize in Bristol in 1685 when he made the mayor of the city, then sitting fully robed beside him on the bench, go into the dock and be fined £1000 for being a 'kidnapping knave'; some Bristol traders at the time were known at the time to kidnap their own countrymen and ship them away as slaves.

Somersett's case in 1772 was generally taken at the time to have decided that the condition of slavery did not exist under English law in England. In 1785, English poet William Cowper wrote: "We have no slaves at home - Then why abroad? Slaves cannot breathe in England; if their lungs receive our air, that moment they are free. They touch our country, and their shackles fall. That's noble, and bespeaks a nation proud. And jealous of the blessing. Spread it then, And let it circulate through every vein." However, slavery continued to thrive in England itself, much like it did in the British Empire, until full emancipation in the 1830s. In 1807, following many years of lobbying by the abolitionist movement, led primarily by William Wilberforce, the British Parliament voted to make the slave trade illegal anywhere in the Empire with the Slave Trade Act 1807. Thereafter Britain took a prominent role in combating the trade, and slavery itself was abolished in the British Empire (except for India) with the Slavery Abolition Act 1833. Between 1808 and 1860, the West Africa Squadron seized approximately 1,600 slave ships and freed 150,000 Africans who were aboard. Action was also taken against African leaders who refused to agree to British treaties to outlaw the trade. Akitoye, the 11th Oba of Lagos, is famous for having used British involvement to regain his rule in return for suppressing slavery among the Yoruba people of Lagos in 1851. Anti-slavery treaties were signed with over 50 African rulers. In 1839, the world's oldest international human rights organization, Anti-Slavery International, was formed in Britain by Joseph Sturge, which worked to outlaw slavery in other countries.

After 1833, the freed African slaves declined employment in the cane fields. This led to the importation of indentured labour again - mainly from India, and also China.

In 1811, Arthur William Hodge was executed for the murder of a slave in the British West Indies. He was not, however, as some have claimed, the first white person to have been lawfully executed for the murder of a slave.

During World War II Nazi Germany operated several categories of Arbeitslager (Labor Camps) for different categories of inmates. The largest number of them held Polish and Jewish civilians forcibly abducted in the occupied countries (see Łapanka) to provide labor in the German war industry, repair bombed railroads and bridges or work on farms. By 1944, 20% of all workers were foreigners, either civilians or prisoners of war.

This is not classed as slavery per se, as defined in the first paragraph, i.e. slavery under this definition does not include other forced labour systems, such as historical forced labor by prisoners, labor camps, or other forms of unfree labor, in which labourers are not legally considered property. Slavery typically requires a shortage of labor and a surplus of land to be viable.

As agreed by the Allies at the Yalta conference Germans were used as forced labor as part of the reparations to be extracted. By 1947 it is estimated that 400,000 Germans (both civilians and POWs) were being used as forced labor by the U.S., France, the UK and the Soviet Union. German prisoners were for example forced to clear minefields in France and the Low Countries. By December 1945 it was estimated by French authorities that 2,000 German prisoners were being killed or injured each month in accidents. In Norway the last available casualty record, from 29 August 1945, shows that by that time a total of 275 German soldiers died while clearing mines, while 392 had been injured. Death rates for the German civilians doing forced labor in the Soviet Union ranged between 19% and 39%, depending on category.

In the first half of the 19th century, small-scale slave raids took place across Polynesia to supply labor and sex workers for the whaling and sealing trades, with examples from both the westerly and easterly extremes of the Polynesian triangle. By the 1860s this had grown to a larger scale operation with Peruvian slave raids in the South Sea Islands to collect labor for the guano industry.

Ancient Hawaii was a caste society. People were born into specific social classes. Kauwa were those of the outcast or slave class. They are believed to have been war captives, or the descendants of war captives. Marriage between higher castes and the kauwa was strictly forbidden. The kauwa worked for the chiefs and were often used as human sacrifices at the luakini heiau. (They were not the only sacrifices; law-breakers of all castes or defeated political opponents were also acceptable as victims.)

The kapu system was abolished during the ʻAi Noa in 1819, and with it the distinction between the kauwā slave class and the makaʻāinana (commoners). The 1852 Constitution of the Kingdom of Hawaii officially made slavery illegal.

Before the arrival of European settlers, each Maori tribe () considered itself a separate entity equivalent to a nation. In traditional Maori society of Aotearoa, prisoners of war became taurekareka, slaves, unless released, ransomed or eaten. With some exceptions, the child of a slave remained a slave.

As far as it is possible to tell, slavery seems to have increased in the early 19th century with increased numbers of prisoners being taken by Māori military leaders, such as Hongi Hika and Te Rauparaha to satisfy the need for labor in the Musket Wars, to supply whalers and traders with food, flax and timber in return for western goods. The intertribal Musket Wars lasted 1807 to 1843 when large numbers of slaves were captured by northern tribes who had acquired muskets. About 20,000 Maori died in the wars which were concentrated in the North Island. An unknown number of slaves were captured. Northern tribes used slaves (called mokai) to grow large areas of potatoes for trade with visiting ships. Chiefs started an extensive sex trade in the Bay of Islands in the 1830s using mainly slave girls. By 1835 about 70-80 ships per year called into the port. One French captain described the impossibility of getting rid of the girls who swarmed over his ship outnumbering his crew of 70 by 3 to 1. All payments to the girls were stolen by the chief. By 1833 Christianity had become established in the north and large numbers of slaves were freed. However two Taranaki tribes, Ngati Tama and Ngati Mutunga, displaced by the wars carried out a carefully planned invasion of the Chatham Islands, 800 km east of Christchurch, in 1835. About 15% of the Polynesian Moriori natives who had migrated to the islands at about 1500 CE were killed, with many women being tortured to death. The remaining population was enslaved for the purpose of growing food, especially potatoes. The Moriori were treated in an inhumane and degrading manner for many years. Their culture was banned and they were forbidden to marry. Slavery was outlawed when the British entered into a constitutional arrangement with New Zealand in 1840 via the Treaty of Waitangi, although it did not end completely until government was effectively extended over the whole of the country with the defeat of the Kingi movement in the Wars of the mid-1860s.

Some Maori took Moriori partners. The state of enslavement of Moriori lasted until the 1860s although it had been discouraged by CMS missionaries in North New Zealand from the late 1820s. In 1870 Ngati Mutunga, one of the invading tribes, argued before the Native Land Court in New Zealand that their gross mistreatment of the Moriori was standard Maori practice or tikanga.

One group of Polynesians who migrated to the Chatham Islands became the Moriori who developed a largely pacifist culture. It was originally speculated that they settled the Chathams direct from Polynesia, but it is now widely believed they were disaffected Maori who emigrated from the South Island of New Zealand. Their pacifism left the Moriori unable to defend themselves when the islands were invaded by mainland Māori in the 1830s. Two Taranaki tribes, Ngati Tama and Ngati Mutunga, displaced by the musket wars, carried out a carefully planned invasion of the Chatham Islands, 800 km east of Christchurch, in 1835. About 15% of the Polynesian Moriori natives who had migrated to the islands at about 1500 CE were killed, with many women being tortured to death. The remaining population was enslaved for the purpose of growing food, especially potatoes. The Moriori were treated in an inhumane and degrading manner for many years. Their culture was banned and they were forbidden to marry. Slavery was outlawed when the British annexed New Zealand in 1840, immediately prior to the signing of the Treaty of Waitangi, although it did not end completely until government was effectively extended over the whole of the country with the defeat of the Kingi movement in the Wars of the mid-1860s.

Some 300 Moriori men, women and children were massacred and the remaining 1,200 to 1,300 survivors were enslaved.

Rapa Nui / Easter Island

The isolated island of Rapa Nui/ Easter Island was inhabited by the Rapanui, who suffered a series of slave raids from 1805 or earlier, culminating in a near genocidal experience in the 1860s. The 1805 raid was by American sealers and was one of a series that changed the attitude of the islanders to outside visitors, with reports in the 1820s and 1830s that all visitors received a hostile reception. In December 1862, Peruvian slave raiders took between 1,400 and 2,000 islanders back to Peru to work in the guano industry; this was about a third of the island's population and included much of the island's leadership, the last ariki-mau and possibly the last who could read Rongorongo. After intervention by the French ambassador in Lima, the last 15 survivors were returned to the island, but brought with them smallpox, which further devastated the island.

Slavery has existed, in one form or another, throughout the whole of human history. So, too, have movements to free large or distinct groups of slaves. However, abolitionism should be distinguished from efforts to help a particular group of slaves, or to restrict one practice, such as the slave trade.

Although there were numerous slave revolts in the Caribbean, the only successful uprising came in the French colony of Haiti in the 1790s, where the slaves rose up, killed the mulattoes and whites, and established the independent Republic of Haiti. Europe recoiled in horror.

Cyrus the Great, the founder of Persian Empire prohibited the systematic enslavement of conquered non-combatant population. Cyrus also freed slaves and allowed all deported peoples who were enslaved by preceding Assyrian and Babylonian kings, to return home. It is said that he freed up to 40,000 Jews and allowed them to return home. Cylinder of Cyrus the Great containing the Decree on the conquered non-combatant population.

In 1772, the Somersett Case (R. v. Knowles, ex parte Somersett) of the English Court of King's Bench ruled that it was unlawful for a slave to be forcibly taken abroad. The case has since been misrepresented as finding that slavery was unlawful in England (although not elsewhere in the British Empire). A similar case, that of Joseph Knight, took place in Scotland five years later and ruled slavery to be contrary to the law of Scotland.

Following the work of campaigners in the United Kingdom, such as William Wilberforce and Thomas Clarkson, the Act for the Abolition of the Slave Trade was passed by Parliament on 25 March 1807, coming into effect the following year. The act imposed a fine of £100 for every slave found aboard a British ship. The intention was to outlaw entirely the Atlantic slave trade within the whole British Empire.

The significance of the abolition of the British slave trade lay in the number of people hitherto sold and carried by British slave vessels. Britain shipped 2,532,300 Africans across the Atlantic, equalling 41% of the total transport of 6,132,900 individuals. This made the British empire the biggest slave-trade contributor in the world due to the magnitude of the empire, which made the abolition act all the more damaging to the global trade of slaves. Britain used its diplomatic influence to press other nations into treaties to ban their slave trade and to give the Royal Navy the right to interdict slave ships sailing under their national flag.

The Slavery Abolition Act, passed on 1 August 1833, outlawed slavery itself throughout the British Empire, with the exception of India. On 1 August 1834 slaves became indentured to their former owners in an apprenticeship system for six years. Full emancipation was granted ahead of schedule on 1 August 1838. Britain abolished slavery in both Hindu and Muslim India with the Indian Slavery Act, 1843.

Domestic slavery practised by the educated African coastal elites (as well as interior traditional rulers) in Sierra Leone was abolished in 1928. A study found practices of domestic slavery still widespread in rural areas in the 1970s.

There were slaves in mainland France (especially in trade ports such as Nantes or Bordeaux)., but the institution was never officially authorized there. The legal case of Jean Boucaux in 1739 clarified the unclear legal position of possible slaves in France, and was followed by laws that established registers for slaves in mainland France, who were limited to a three-year stay, for visits or learning a trade. Unregistered "slaves" in France were regarded as free. However, slavery was of vital importance in France's Caribbean possessions, especially Saint-Domingue.

In 1793, influenced by the French Declaration of the Rights of Man of August 1789 and alarmed as the massive slave revolt of August 1791 that had become the Haitian Revolution threatened to ally itself with the British, the French Revolutionary commissioners Sonthonax and Polverel declared general emancipation to reconcile them with France. In Paris, on 4 February 1794, Abbé Grégoire and the Convention ratified this action by officially abolishing slavery in all French territories outside mainland France, freeing all the slaves both for moral and security reasons.

Napoleon came to power in 1799 and soon had grandiose plans for the French sugar colonies; to achieve them he reintroduced slavery. Napoleon's major adventure into the Caribbean-sending 30,000 troops in 1802 to retake Saint Domingue (Haiti) from ex-slaves under Toussaint L'Ouverture who had revolted. Napoleon wanted to preserve France's financial benefits from the colony's sugar and coffee crops; he then planned to establish a major base at New Orleans. He therefore re-established slavery in Haiti and Guadeloupe, where it had been abolished after rebellions. Slaves and black freedmen fought the French for their freedom and independence. Revolutionary ideals played a central role in the fighting for it was the slaves and their allies who were fighting for the revolutionary ideals of freedom and equality, while the French troops under General Charles Leclerc fought to restore the order of the ancien régime. The goal of re-establishing slavery explicitly contradicted the ideals of the French Revolution. The French soldiers were unable to cope with the tropical diseases, and most died of yellow fever. Slavery was reimposed in Guadeloupe but not in Haiti, which became an independent black republic. Napoleon's vast colonial dreams for Egypt, India, the Caribbean, Louisiana, and even Australia were all doomed for lack of a fleet capable of matching Britain's Royal Navy. Realizing the fiasco Napoleon liquidated the Haiti project, brought home the survivors and sold off the huge Louisiana territory to the US in 1803.

In 1794 slavery was abolished in the French Empire. After seizing Lower Egypt in 1798, Napoleon Bonaparte issued a proclamation in Arabic, declaring all men to be free and equal. However, the French bought males as soldiers and females as concubines. Napoleon personally opposed the abolition and restored colonial slavery in 1802, a year after the capitulation of his troops in Egypt.

Victor Schœlcher and the 1848 abolition

The American Colonization Society, the primary vehicle for returning black Americans to greater freedom in Africa, established the colony of Liberia in 1821-23, on the premise that former American slaves would have greater freedom and equality there. The ACS assisted in the movement of thousands of African Americans to Liberia, with its founder Henry Clay stating; "unconquerable prejudice resulting from their color, they never could amalgamate with the free whites of this country. It was desirable, therefore, as it respected them, and the residue of the population of the country, to drain them off". Abraham Lincoln, an enthusiastic supporter of Clay, adopted his position on returning the blacks to their own land.

Slaves in the United States who escaped ownership would often make their way to Canada via the " Underground Railroad". The more famous of the African American abolitionists include former slaves Harriet Tubman, Sojourner Truth and Frederick Douglass. Many more people who opposed slavery and worked for abolition were northern whites, such as William Lloyd Garrison and John Brown. Slavery was legally abolished in 1865 by the Thirteenth Amendment to the United States Constitution.

While abolitionists agreed on the evils of slavery, there were differing opinions on what should happen after African Americans were freed. By the time of Emancipation, African-Americans were now native to the United States and did not want to leave. Most believed that their labor had made the land theirs as well as that of the whites.

The Declaration of the Powers, on the Abolition of the Slave Trade, of 8 February 1815 (Which also formed ACT, No. XV. of the Final Act of the Congress of Vienna of the same year) included in its first sentence the concept of the "principles of humanity and universal morality" as justification for ending a trade that was "odious in its continuance".

The 1926 Slavery Convention, an initiative of the League of Nations, was a turning point in banning global slavery. Article 4 of the Universal Declaration of Human Rights, adopted in 1948 by the UN General Assembly, explicitly banned slavery. The United Nations 1956 Supplementary Convention on the Abolition of Slavery was convened to outlaw and ban slavery worldwide, including child slavery. In December 1966, the UN General Assembly adopted the International Covenant on Civil and Political Rights, which was developed from the Universal Declaration of Human Rights. Article 4 of this international treaty bans slavery. The treaty came into force in March 1976 after it had been ratified by 35 nations.

As of November 2003, 104 nations had ratified the treaty. However, illegal forced labour involves millions of people in the 21st century, 43% for sexual exploitation and 32% for economic exploitation.

In May 2004, the 22 members of the Arab League adopted the Arab Charter on Human Rights, which incorporated the 1990 Cairo Declaration on Human Rights in Islam, which states:

Human beings are born free, and no one has the right to enslave, humiliate, oppress or exploit them, and there can be no subjugation but to God the Most-High.

-  Article 11, Cairo Declaration on Human Rights in Islam, 1990

Currently, the Anti-trafficking Coordination Team Initiative (ACT Team Initiative), a coordinated effort between the U.S. departments of justice, homeland security and labor, addresses human trafficking. The International Labour Organization estimates that there are 20.9 million victims of human trafficking globally, including 5.5 million children, of which 55% are women and girls.

The history of slavery originally was the history of the government's laws and policies toward slavery, and the political debates about it. Black history was promoted very largely at black colleges. The situation changed dramatically with the coming of the Civil Rights Movement of the 1950s. Attention shifted to the enslaved humans, the free blacks, and the struggles of the black community against adversity.

Peter Kolchin described the state of historiography in the early 20th century as follows:

During the first half of the twentieth century, a major component of this approach was often simply racism, manifest in the belief that blacks were, at best, imitative of whites. Thus Ulrich B. Phillips, the era's most celebrated and influential expert on slavery, combined a sophisticated portrait of the white planters' life and behavior with crude passing generalizations about the life and behavior of their black slaves.

Historians James Oliver Horton and Lois E. Horton described Phillips' mindset, methodology and influence:

His portrayal of blacks as passive, inferior people, whose African origins made them uncivilized, seemed to provide historical evidence for the theories of racial inferiority that supported racial segregation. Drawing evidence exclusively from plantation records, letters, southern newspapers, and other sources reflecting the slaveholder's point of view, Phillips depicted slave masters who provided for the welfare of their slaves and contended that true affection existed between master and slave.

Their account of the era rested, as one member of the Dunning school put it, on the assumption of "negro incapacity." Finding it impossible to believe that blacks could ever be independent actors on the stage of history, with their own aspirations and motivations, Dunning et al. portrayed African Americans either as "children", ignorant dupes manipulated by unscrupulous whites, or as savages, their primal passions unleashed by the end of slavery.

In the portrayal of the slave as a victim, the historian Stanley M. Elkins in his 1959 work Slavery: A Problem in American Institutional and Intellectual Life compared the effects of United States slavery to that resulting from the brutality of the Nazi concentration camps. He stated the institution destroyed the will of the slave, creating an "emasculated, docile Sambo" who identified totally with the owner. Elkins' thesis was challenged by historians. Gradually historians recognized that in addition to the effects of the owner-slave relationship, slaves did not live in a "totally closed environment but rather in one that permitted the emergence of enormous variety and allowed slaves to pursue important relationships with persons other than their master, including those to be found in their families, churches and communities."

Economic historians Robert W. Fogel and Stanley L. Engerman in the 1970s, through their work Time on the Cross, portrayed slaves as having internalized the Protestant work ethic of their owners. In portraying the more benign version of slavery, they also argue in their 1974 book that the material conditions under which the slaves lived and worked compared favorably to those of free workers in the agriculture and industry of the time. (This was also an argument of Southerners during the 19th century.)

In the 1970s and 1980s, historians made use of sources such as black music and statistical census data to create a more detailed and nuanced picture of slave life. Relying also on 19th-century autobiographies of ex-slaves (known as slave narratives) and the WPA Slave Narrative Collection, a set of interviews conducted with former slaves in the 1930s by the Federal Writers' Project, historians described slavery as the slaves remembered it. Far from slaves' being strictly victims or content, historians showed slaves as both resilient and autonomous in many of their activities. Despite their exercise of autonomy and their efforts to make a life within slavery, current historians recognize the precariousness of the slave's situation. Slave children quickly learned that they were subject to the direction of both their parents and their owners. They saw their parents disciplined just as they came to realize that they also could be physically or verbally abused by their owners. Historians writing during this era include John Blassingame ( Slave Community), Eugene Genovese ( Roll, Jordan, Roll), Leslie Howard Owens ( This Species of Property), and Herbert Gutman ( The Black Family in Slavery and Freedom).

Important work on slavery has continued; for instance, in 2003 Steven Hahn published the Pulitzer Prize-winning account, A Nation under Our Feet: Black Political Struggles in the Rural South from Slavery to the Great Migration, which examined how slaves built community and political understanding while enslaved, so they quickly began to form new associations and institutions when emancipated, including black churches separate from white control. In 2010, Robert E. Wright published a model that explains why slavery was more prevalent in some areas than others (e.g. southern than northern Delaware) and why some firms (individuals, corporations, plantation owners) chose slave labor while others used wage, indentured, or family labor instead.

Historical revisionism arrived when West Indian historian Eric Williams, a Marxist, in Capitalism and Slavery (1944), rejected this moral explanation and argued that abolition was now more profitable, for a century of sugarcane raising had exhausted the soil of the islands, and the plantations had become unprofitable. It was more profitable to sell the slaves to the government than to keep up operations. The 1807 prohibition of the international trade, Williams argued, prevented French expansion on other islands. Meanwhile, British investors turned to Asia, where labor was so plentiful that slavery was unnecessary. Williams went on to argue that slavery played a major role in making Britain prosperous. The high profits from the slave trade, he said, helped finance the Industrial Revolution. Britain enjoyed prosperity because of the capital gained from the unpaid work of slaves.

Since the 1970s numerous historians have challenged Williams from various angles and Gad Heuman has concluded, "More recent research has rejected this conclusion; it is now clear that the colonies of the British Caribbean profited considerably during the Revolutionary and Napoleonic Wars." In his major attack on the Williams's thesis, Seymour Drescher argues that Britain's abolition of the slave trade in 1807 resulted not from the diminishing value of slavery for Britain but instead from the moral outrage of the British voting public. Critics have also argued that slavery remained profitable in the 1830s because of innovations in agriculture so the profit motive was not central to abolition. Richardson (1998) finds Williams's claims regarding the Industrial Revolution are exaggerated, for profits from the slave trade amounted to less than 1% of domestic investment in Britain. Richardson further challenges claims (by African scholars) that the slave trade caused widespread depopulation and economic distress in Africa-indeed that it caused the "underdevelopment" of Africa. Admitting the horrible suffering of slaves, he notes that many Africans benefited directly because the first stage of the trade was always firmly in the hands of Africans. European slave ships waited at ports to purchase cargoes of people who were captured in the hinterland by African dealers and tribal leaders. Richardson finds that the "terms of trade" (how much the ship owners paid for the slave cargo) moved heavily in favor of the Africans after about 1750. That is, indigenous elites inside West and Central Africa made large and growing profits from slavery, thus increasing their wealth and power.

Economic historian Stanley Engerman finds that even without subtracting the associated costs of the slave trade (e.g., shipping costs, slave mortality, mortality of British people in Africa, defense costs) or reinvestment of profits back into the slave trade, the total profits from the slave trade and of West Indian plantations amounted to less than 5% of the British economy during any year of the Industrial Revolution. Engerman's 5% figure gives as much as possible in terms of benefit of the doubt to the Williams argument, not solely because it does not take into account the associated costs of the slave trade to Britain, but also because it carries the full-employment assumption from economics and holds the gross value of slave trade profits as a direct contribution to Britain's national income. Historian Richard Pares, in an article written before Williams's book, dismisses the influence of wealth generated from the West Indian plantations upon the financing of the Industrial Revolution, stating that whatever substantial flow of investment from West Indian profits into industry there was occurred after emancipation, not before.

The history of slavery spans many cultures, nationalities, and religions from ancient times to the present day. However the social, economic, and legal positions of slaves have differed vastly in different systems of slavery in different times and places.

Slavery occurs relatively rarely among hunter-gatherer populations because it develops under conditions of social stratification. Slavery operated in the very first civilizations (such as Sumer in Mesopotamia, which dates back as far as 3500 BCE). Slavery features in the Mesopotamian Code of Hammurabi (c. 1860 BCE), which refers to it as an established institution. Slavery became common within much of Europe during the Early Middle Ages and it continued into the following centuries. The Byzantine-Ottoman wars (1265-1479) and the Ottoman wars in Europe (14th to 20th centuries) resulted in the capture of large numbers of Christian slaves. The Dutch, French, Spanish, Portuguese, British, Arabs and a number of West African kingdoms played a prominent role in the Atlantic slave trade, especially after 1600. The Republic of Ragusa became the first European country to ban the slave trade in 1416. In modern times Denmark-Norway abolished the trade in 1802.

Although slavery is no longer legal anywhere in the world (with the exception of penal labour), human trafficking remains an international problem and an estimated 25-40 million people were enslaved as of 2013, the majority in Asia. During the 1983-2005 Second Sudanese Civil War people were taken into slavery. Evidence emerged in the late 1990s of systematic child-slavery and -trafficking on cacao plantations in West Africa. Slavery continues into the 21st century. Although Mauritania criminalized slavery in August 2007, an estimated up to 600,000 men, women and children, or 20% of the population of Mauritania, are currently enslaved, many of them used as bonded labor. Slavery in the 21st century continues, with the top ten countries with the highest prevalence according to the Global Slavery Index being North Korea, Eritrea, Burundi, the Central African Republic, Afghanistan, Mauritania, South Sudan, Pakistan, Cambodia and Iran. Islamist quasi-states such as the Islamic State of Iraq and the Levant and Boko Haram have abducted and enslaved women and children (often to serve as sex slaves).

Evidence of slavery predates written records, and has existed in many cultures. Mass slavery requires economic surpluses and a high population density to be viable. Due to these factors, the practice of slavery would have only proliferated after the invention of agriculture during the Neolithic Revolution, about 11,000 years ago.

C. 1480 BCE, fugitive slave treaty between Idrimi of Alakakh (now Tell Atchana) and Pillia of Kizzuwatna (now Cilicia).

French historian Fernand Braudel noted that slavery was endemic in Africa and part of the structure of everyday life. "Slavery came in different guises in different societies: there were court slaves, slaves incorporated into princely armies, domestic and household slaves, slaves working on the land, in industry, as couriers and intermediaries, even as traders". During the 16th century, Europe began to outpace the Arab world in the export traffic, with its slave traffic from Africa to the Americas. The Dutch imported slaves from Asia into their colony in South Africa. In 1807 Britain, which held extensive, although mainly coastal, colonial territories on the African continent (including southern Africa), made the international slave trade illegal, as did the United States in 1808.

Slavery in Ethiopia persisted until 1942. The Anti-Slavery Society estimated that there were 2,000,000 slaves in the early 1930s, out of an estimated population of between 8 and 16 million. It was finally abolished by order of emperor Haile Selassie on 26 August 1942.

When British rule was first imposed on the Sokoto Caliphate and the surrounding areas in northern Nigeria at the turn of the 20th century, approximately 2 million to 2.5 million people there were slaves. Slavery in northern Nigeria was finally outlawed in 1936.

Elikia M'bokolo, April 1998, Le Monde diplomatique. Quote: "The African continent was bled of its human resources via all possible routes. Across the Sahara, through the Red Sea, from the Indian Ocean ports and across the Atlantic. At least ten centuries of slavery for the benefit of the Muslim countries (from the ninth to the nineteenth)." He continues: "Four million slaves exported via the Red Sea, another four million through the Swahili ports of the Indian Ocean, perhaps as many as nine million along the trans-Saharan caravan route, and eleven to twenty million (depending on the author) across the Atlantic Ocean"

Zanzibar was once East Africa's main slave-trading port, and under Omani Arabs in the 19th century, as many as 50,000 slaves were passing through the city each year.

Prior to the 16th century, the bulk of slaves exported from Africa were shipped from East Africa to the Arabian peninsula. Zanzibar became a leading port in this trade. Arab slave traders differed from European ones in that they would often conduct raiding expeditions themselves, sometimes penetrating deep into the continent. They also differed in that their market greatly preferred the purchase of female slaves over male ones.

The increased presence of European rivals along the East coast led Arab traders to concentrate on the overland slave caravan routes across the Sahara from the Sahel to North Africa. The German explorer Gustav Nachtigal reported seeing slave caravans departing from Kukawa in Bornu bound for Tripoli and Egypt in 1870. The slave trade represented the major source of revenue for the state of Bornu as late as 1898. The eastern regions of the Central African Republic have never recovered demographically from the impact of 19th-century raids from the Sudan and still have a population density of less than 1 person/km². During the 1870s, European initiatives against the slave trade caused an economic crisis in northern Sudan, precipitating the rise of Mahdist forces. Mahdi's victory created an Islamic state, one that quickly reinstituted slavery.

The Middle Passage, the crossing of the Atlantic to the Americas, endured by slaves laid out in rows in the holds of ships, was only one element of the well-known triangular trade engaged in by Portuguese, Dutch, Danish-Norwegians, French, British and others. Ships having landed slaves in Caribbean ports would take on sugar, indigo, raw cotton, and later coffee, and make for Liverpool, Nantes, Lisbon or Amsterdam. Ships leaving European ports for West Africa would carry printed cotton textiles, some originally from India, copper utensils and bangles, pewter plates and pots, iron bars more valued than gold, hats, trinkets, gunpowder and firearms and alcohol. Tropical shipworms were eliminated in the cold Atlantic waters, and at each unloading, a profit was made.

While talking about the slave trade in East Africa in his journals, "To overdraw its evil is a simple impossibility."

To overdraw its evil is a simple impossibility.

David Livingstone while travelling in the African Great Lakes Region in 1866 described a trail of slaves as such:

19th June 1866 - We passed a woman tied by the neck to a tree and dead, the people of the country explained that she had been unable to keep up with the other slaves in a gang, and her master had determined that she should not become anyone's property if she recovered.
26th June. - ...We passed a slave woman shot or stabbed through the body and lying on the path: a group of men stood about a hundred yards off on one side, and another of the women on the other side, looking on; they said an Arab who passed early that morning had done it in anger at losing the price he had given for her, because she was unable to walk any longer.
27th June 1866 - To-day we came upon a man dead from starvation, as he was very thin. One of our men wandered and found many slaves with slave-sticks on, abandoned by their masters from want of food; they were too weak to be able to speak or say where they had come from; some were quite young.

The strangest disease I have seen in this country seems really to be broken-heartedness, and it attacks free men who have been captured and made slaves... Twenty one were unchained, as now safe; however all ran away at once; but eight with many others still in chains, died in three days after the crossing. They described their only pain in the heart, and placed the hand correctly on the spot, though many think the organ stands high up in the breast-bone.

African states played a role in the slave trade, and slavery was a common practice among Sub Saharan Africans before the involvement of the Arabs, Berbers and Europeans. There were three types: those who were slaves through conquest, those who were slaves due to unpaid debts, or those whose parents gave them as slaves to tribal chiefs. Chieftains would barter their slaves to Arab, Berber, Ottoman or European buyers for rum, spices, cloth or other goods. Selling captives or prisoners was commonly practiced among Africans, Turks, Berbers and Arabs during that era. However, as the Atlantic slave trade increased its demand, local systems which primarily serviced indentured servitude expanded. European slave trading, as a result, was the most pivotal change in the social, economic, cultural, spiritual, religious, political dynamics of the concept of slave trading. It ultimately undermined local economies and political stability as villages' vital labour forces were shipped overseas as slave raids and civil wars became commonplace. Crimes which were previously punishable by some other means became punishable by enslavement.

The kings of Dahomey sold their war captives into transatlantic slavery, who otherwise may have been killed in a ceremony known as the Annual Customs. As one of West Africa's principal slave states, Dahomey became extremely unpopular with neighbouring peoples. Like the Bambara Empire to the east, the Khasso kingdoms depended heavily on the slave trade for their economy. A family's status was indicated by the number of slaves it owned, leading to wars for the sole purpose of taking more captives. This trade led the Khasso into increasing contact with the European settlements of Africa's west coast, particularly the French. Benin grew increasingly rich during the 16th and 17th centuries on the slave trade with Europe; slaves from enemy states of the interior were sold, and carried to the Americas in Dutch and Portuguese ships. The Bight of Benin's shore soon came to be known as the "Slave Coast".

The slave trade is the ruling principle of my people. It is the source and the glory of their wealth...the mother lulls the child to sleep with notes of triumph over an enemy reduced to slavery...

In 1807, under internal and external pressures, the United Kingdom made illegal the international trade in slaves. The Royal Navy was deployed to prevent slavers from the United States, France, Spain, Portugal, Holland, West Africa and Arabia. The King of Bonny (now in Nigeria) allegedly became dissatisfied of the British intervention in stopping slave trading.

We think this trade must go on. That is the verdict of our oracle and the priests. They say that your country, however great, can never stop a trade ordained by God himself.

Joseph Miller states that African buyers would prefer males, but in reality, women and children would be more easily captured as men fled. Those captured would be sold for various reasons such as food, debts, or servitude. Once captured, the journey to the coast killed many and weakened others. Disease engulfed many, and insufficient food damaged those who made it to the coasts. Scurvy was so common that it was known as mal de Luanda (Luanda sickness). The assumption for those who died on the journey died from malnutrition. As food was limited, water may have been just as bad. Dysentery was widespread and poor sanitary conditions at ports did not help. Since supplies were poor, slaves were not equipped with the best clothing that further exposed to more diseases.

If the fear of disease caused terror, the psyche of slaves for being captured was just as terrifying. The most popular assumption for being captured was Europeans were cannibals. Stories and rumours spread that whites captured Africans to eat them. Olaudah Equiano accounts his experience about the sorrow slaves encountered at the ports. He talks about his first moment on a slave ship and asked if he was going to be eaten. Yet, the worst for slaves has only begun, and the journey on the water proved to be more terrifying. For every 100 Africans captured, only 64 would reach the coast, and only about 50 would reach the New World.

Others believe that slavers had a vested interest in capturing rather than killing, and in keeping their captives alive; and that this coupled with the disproportionate removal of males and the introduction of new crops from the Americas ( cassava, maize) would have limited general population decline to particular regions of western Africa around 1760-1810, and in Mozambique and neighbouring areas half a century later. There has also been speculation that within Africa, females were most often captured as brides, with their male protectors being a "bycatch" who would have been killed if there had not been an export market for them.

British explorer Mungo Park encountered a group of slaves when traveling through Mandinka country:

They were all very inquisitive, but they viewed me at first with looks of horror, and repeatedly asked if my countrymen were cannibals. They were very desirous to know what became of the slaves after they had crossed the salt water. I told them that they were employed in cultivation the land; but they would not believe me ... A deeply-rooted idea that the whites purchase negroes for the purpose of devouring them, or of selling them to others that they may be devoured hereafter, naturally makes the slaves contemplate a journey towards the coast with great terror, insomuch that the slatees are forced to keep them constantly in irons, and watch them very closely, to prevent their escape.

During the period from the late 19th century and early 20th century, demand for the labour-intensive harvesting of rubber drove frontier expansion and forced labour. The personal monarchy of Belgian King Leopold II in the Congo Free State saw mass killings and slavery to extract rubber.

Stephanie Smallwood in her book Saltwater Slavery uses Equiano's account on board ships to describe the general thoughts of most slaves.

Then," said I, "how comes it in all our country we never heard of them?" They told me because they lived so very far off. I then asked where were their women? Had they any like themselves? I was told that they had. "And why," said I, "do we not see them?" They answered, because they were left behind. I asked how the vessel could go? They told me they could not tell; but that there was cloth put upon the masts by the help of the ropes I saw, and then the vessel went on; and the white men had some spell or magic they put in the water when they liked, in order to stop the vessel. I was exceedingly amazed at this account, and really thought they were spirits. I there-fore wished much to be from amongst them, for I expected they would sacrifice me; but my wishes were vain-for we were so quartered that it was impossible for any of us to make our escape.

Accounts like these raised many questions as some slaves grew philosophical with their journey. Smallwood points out the challenges for slaves were physical and metaphysical. The physical would be obvious as the challenge to overcome capacity, lack of ship room, and food. The metaphysical was unique as the open sea would challenge African slaves' vision of the ocean as habitable. At essence, the journey on the ocean would prove to be an African's biggest fear that would keep them in awe. Combining this with the lack of knowledge of the sea, Africans would be entering a world of anxiety never seen before. Yet, Europeans were also fearful of the sea, but not to the extent of Africans. One of these dilemmas came with the sense of time. Africans used seasonal weather to predict time and days. The moon was a sense of time, but used like in other cultures. On the sea, Africans used the moon to best count the days, but the sea did not provide seasonal changes for them to know how long they were at sea. Counting the days on a ship was not the main priority, however. Surviving the voyage was the main horror. No one escaped diseases as the close quarters infected everyone including the crew. Death was so common that ships were called tumbeiros or floating tombs. What shocked Africans the most was how death was handled in the ships. Smallwood says the traditions for an African death was delicate and community-based. On ships, bodies would be thrown into the sea. Because the sea represented bad omens, bodies in the sea represented a form of purgatory and the ship a form of hell. In the end, the Africans who made the journey would have survived disease, malnutrition, confined space, close death, and the trauma of the ship.

In Algiers during the time of the Regency of Algiers in North Africa in the 19th century, 1.5 million Christians and Europeans were captured and forced into slavery. This eventually led to the Bombardment of Algiers in 1816 by the British and Dutch, forcing the Dey of Algiers to free many slaves.

The trading of children has been reported in modern Nigeria and Benin. In parts of Ghana, a family may be punished for an offense by having to turn over a virgin female to serve as a sex slave within the offended family. In this instance, the woman does not gain the title or status of "wife". In parts of Ghana, Togo, and Benin, shrine slavery persists, despite being illegal in Ghana since 1998. In this system of ritual servitude, sometimes called trokosi (in Ghana) or voodoosi in Togo and Benin, young virgin girls are given as slaves to traditional shrines and are used sexually by the priests in addition to providing free labor for the shrine.

An article in the Middle East Quarterly in 1999 reported that slavery is endemic in Sudan. Estimates of abductions during the Second Sudanese Civil War range from 14,000 to 200,000 people.

During the Second Sudanese Civil War people were taken into slavery; estimates of abductions range from 14,000 to 200,000. Abduction of Dinka women and children was common. In Mauritania it is estimated that up to 600,000 men, women and children, or 20% of the population, are currently enslaved, many of them used as bonded labor. Slavery in Mauritania was criminalized in August 2007.

During the Darfur conflict that began in 2003, many people were kidnapped by Janjaweed and sold into slavery as agricultural labor, domestic servants and sex slaves.

In Niger, slavery is also a current phenomenon. A Nigerien study has found that more than 800,000 people are enslaved, almost 8% of the population. Niger installed an anti-slavery provision in 2003. In a landmark ruling in 2008, the ECOWAS Community Court of Justice declared that the Republic of Niger failed to protect Hadijatou Mani Koraou from slavery, and awarded Mani CFA 10,000,000 (approximately US$20,000) in reparations.

Sexual slavery and forced labor are common in the Democratic Republic of Congo.

Many pygmies in the Republic of Congo and Democratic Republic of Congo belong from birth to Bantus in a system of slavery.

Evidence emerged in the late 1990s of systematic slavery in cacao plantations in West Africa; see the chocolate and slavery article.

On the night of 14-15 April 2014, a group of militants attacked the Government Girls Secondary School in Chibok, Nigeria. They broke into the school, pretending to be guards, telling the girls to get out and come with them. A large number of students were taken away in trucks, possibly into the Konduga area of the Sambisa Forest where Boko Haram were known to have fortified camps. Houses in Chibok were also burned down in the incident. According to police, approximately 276 children were taken in the attack, of whom 53 had escaped as of 2 May. Other reports said that 329 girls were kidnapped, 53 had escaped and 276 were still missing. The students have been forced to convert to Islam and into marriage with members of Boko Haram, with a reputed " bride price" of ₦2,000 each ($12.50/ £7.50). Many of the students were taken to the neighbouring countries of Chad and Cameroon, with sightings reported of the students crossing borders with the militants, and sightings of the students by villagers living in the Sambisa Forest, which is considered a refuge for Boko Haram.

On 5 May 2014 a video in which Boko Haram leader Abubakar Shekau claimed responsibility for the kidnappings emerged. Shekau claimed that "Allah instructed me to sell them...I will carry out his instructions" and "[s]lavery is allowed in my religion, and I shall capture people and make them slaves." He said the girls should not have been in school and instead should have been married since girls as young as nine are suitable for marriage.

During the Second Libyan Civil War Libyans started capturing some of the Sub-Saharan African migrants trying to get to Europe through Libya and selling them on slave markets. Slaves are often ransomed to their families and in the meantime until ransom can be paid, they may be tortured, forced to work, sometimes worked to death, and eventually they may be executed or left to starve if the payment has not been made after a period of time. Women are often raped and used as sex slaves and sold to brothels.

Many child migrants also suffer from abuse and child rape in Libya.

In Pre-Columbian Mesoamerica the most common forms of slavery were those of prisoners of war and debtors. People unable to pay back debts could be sentenced to work as slaves to the persons owed until the debts were worked off. Warfare was important to Maya society, because raids on surrounding areas provided the victims required for human sacrifice, as well as slaves for the construction of temples. Most victims of human sacrifice were prisoners of war or slaves. Slavery was not usually hereditary; children of slaves were born free. In the Inca Empire, workers were subject to a in lieu of taxes which they paid by working for the government. Each , or extended family, would decide which family member to send to do the work. It is unclear if this labor draft or corvée counts as slavery. The Spanish adopted this system, particularly for their silver mines in Bolivia.

Other slave-owning societies and tribes of the New World were, for example, the Tehuelche of Patagonia, the Comanche of Texas, the Caribs of Dominica, the Tupinambá of Brazil, the fishing societies, such as the Yurok, that lived along the coast from what is now Alaska to California, the Pawnee and Klamath. Many of the indigenous peoples of the Pacific Northwest Coast, such as the Haida and Tlingit, were traditionally known as fierce warriors and slave-traders, raiding as far as California. Slavery was hereditary, the slaves being prisoners of war. Among some Pacific Northwest tribes about a quarter of the population were slaves. One slave narrative was composed by an Englishman, John R. Jewitt, who had been taken alive when his ship was captured in 1802; his memoir provides a detailed look at life as a slave, and asserts that a large number were held.

During the period from the late 19th century and early 20th century, demand for the labor-intensive harvesting of rubber drove frontier expansion and slavery in Latin America and elsewhere. Indigenous peoples were enslaved as part of the rubber boom in Ecuador, Peru, Colombia, and Brazil. In Central America, rubber tappers participated in the enslavement of the indigenous Guatuso-Maleku people for domestic service.

Slavery was a mainstay of the Brazilian colonial economy, especially in mining and sugarcane production. 35.3% of all slaves involved in the Atlantic Slave trade went to Brazil. 4 million slaves were obtained by Brazil, 1.5 million more than any other country. Starting around 1550, the Portuguese began to trade African slaves to work the sugar plantations, once the native Tupi people deteriorated. Although Portuguese Prime Minister Sebastião José de Carvalho e Melo, 1st Marquis of Pombal abolished slavery in mainland Portugal on 12 February 1761, slavery continued in her overseas colonies. Slavery was practiced among all classes. Slaves were owned by upper and middle classes, by the poor, and even by other slaves.

From São Paulo, the Bandeirantes, adventurers mostly of mixed Portuguese and native ancestry, penetrated steadily westward in their search for Indian slaves. Along the Amazon river and its major tributaries, repeated slaving raids and punitive attacks left their mark. One French traveler in the 1740s described hundreds of miles of river banks with no sign of human life and once-thriving villages that were devastated and empty. In some areas of the Amazon Basin, and particularly among the Guarani of southern Brazil and Paraguay, the Jesuits had organized their Jesuit Reductions along military lines to fight the slavers. In the mid-to-late 19th century, many Amerindians were enslaved to work on rubber plantations.

Escaped slaves formed Maroon communities which played an important role in the histories of Brazil and other countries such as Suriname, Puerto Rico, Cuba, and Jamaica. In Brazil, the Maroon villages were called palenques or quilombos. Maroons survived by growing vegetables and hunting. They also raided plantations. At these attacks, the maroons would burn crops, steal livestock and tools, kill slavemasters, and invite other slaves to join their communities.

Jean-Baptiste Debret, a French painter who was active in Brazil in the first decades of the 19th century, started out with painting portraits of members of the Brazilian Imperial family, but soon became concerned with the slavery of both blacks and indigenous inhabitants. His paintings on the subject (two appear on this page) helped bring attention to the subject in both Europe and Brazil itself.

The Clapham Sect, a group of evangelical reformers, campaigned during much of the 19th century for Britain to use its influence and power to stop the traffic of slaves to Brazil. Besides moral qualms, the low cost of slave-produced Brazilian sugar meant that British colonies in the West Indies were unable to match the market prices of Brazilian sugar, and each Briton was consuming 16 pounds (7 kg) of sugar a year by the 19th century. This combination led to intensive pressure from the British government for Brazil to end this practice, which it did by steps over several decades.

Brazil's 1877-78 Grande Seca (Great Drought) in the cotton-growing northeast led to major turmoil, starvation, poverty and internal migration. As wealthy plantation holders rushed to sell their slaves south, popular resistance and resentment grew, inspiring numerous emancipation societies. They succeeded in banning slavery altogether in the province of Ceará by 1884. Slavery was legally ended nationwide on 13 May by the ("Golden Law") of 1888. It was an institution in decadence at these times, as since the 1880s the country had begun to use European immigrant labor instead. Brazil was the last nation in the Western Hemisphere to abolish slavery.

Slavery was commonly used in the parts of the Caribbean controlled by France and the British Empire. The Lesser Antilles islands of Barbados, St. Kitts, Antigua, Martinique and Guadeloupe, which were the first important slave societies of the Caribbean, began the widespread use of African slaves by the end of the 17th century, as their economies converted from sugar production.

England had multiple sugar islands in the Caribbean, especially Jamaica, Barbados, Nevis, and Antigua, which provided a steady flow of sugar sales; slave labor produced the sugar. By the 1700s, there were more slaves in Barbados than all the colonies combined. Since Barbados did not have many mountains, the British were able to clear land for sugar cane. Indentured servants were initially sent to Barbados to work in the sugar fields. These indentured servants were treated so poorly that future indentured servants stopped going to Barbados, and there were not enough people to work the fields. This is when the British started bringing in African slaves. It was important for the slaves to be in Barbados because sugar had become a necessity for most people and the demand for it was high.

An important result of Britain's victory in the War of the Spanish Succession (1702-1714) was enlarging its role in the slave trade. Of special importance was the successful secret negotiation with France to obtain thirty-year monopoly on the Spanish slave trade, called the Queen Anne of Great Britain also allowed her North American colonies like Virginia to make laws that promoted black slavery. Anne had secretly negotiated with France to get its approval regarding the Asiento. She boasted to Parliament of her success in taking the Asiento away from France and London celebrated her economic coup. Most of the slave trade involved sales to Spanish colonies in the Caribbean, and to Mexico, as well as sales to British colonies in the Caribbean and in North America. Historian Vinita Ricks says the agreement allotted Queen Anne "22.5% (and King Philip V, of Spain 28%) of all profits collected for her personal fortune." Ricks concludes that the Queen's "connection to slave trade revenue meant that she was no longer a neutral observer. She had a vested interest in what happened on slave ships."

By 1778, the French were importing approximately 13,000 Africans for enslavement yearly to the French West Indies.

To regularise slavery, in 1685 Louis XIV had enacted the , which accorded certain human rights to slaves and responsibilities to the master, who was obliged to feed, clothe and provide for the general well-being of his slaves. Free blacks owned one-third of the plantation property and one-quarter of the slaves in Saint Domingue (later Haiti). Slavery in the French First Republic was abolished on 4 February 1794. When it became clear that Napoleon intended to re-establish slavery in Haiti, Dessalines and Pétion switched sides, in October 1802. On 1 January 1804, Jean-Jacques Dessalines, the new leader under the dictatorial 1801 constitution, declared Haiti a free republic. Thus Haiti became the second independent nation in the Western Hemisphere, after the United States, and the only successful slave rebellion in world history.

Whitehall in England announced in 1833 that slaves in its territories would be totally freed by 1840. In the meantime, the government told slaves they had to remain on their plantations and would have the status of "apprentices" for the next six years.

In Port-of-Spain, Trinidad, on 1 August 1834, an unarmed group of mainly elderly Negroes being addressed by the Governor at Government House about the new laws, began chanting: "Pas de six ans. Point de six ans" ("Not six years. No six years"), drowning out the voice of the Governor. Peaceful protests continued until a resolution to abolish apprenticeship was passed and de facto freedom was achieved. Full emancipation for all was legally granted ahead of schedule on 1 August 1838, making Trinidad the first British colony with slaves to completely abolish slavery.

In late August 1619, the frigate , a privateer ship owned by Robert Rich, 2nd Earl of Warwick, but flying a Dutch flag arrived at Point Comfort, Virginia (several miles downstream from the colony of Jamestown, Virginia) with the first recorded slaves from Africa to Virginia. The approximately 20 Africans were from the present-day Angola. They had been removed by the White Lion's crew from a Portuguese slave ship, the São João Bautista.

Only a fraction of the enslaved Africans brought to the New World came to British North America, perhaps as little as 5% of the total. The vast majority of slaves were sent to the Caribbean sugar colonies, Brazil, or Spanish America.

By the 1680s, with the consolidation of England's Royal African Company, enslaved Africans were arriving in English colonies in larger numbers, and the institution continued to be protected by the British government. Colonists now began purchasing slaves in larger numbers.

1640: Virginia courts sentence John Punch to lifetime slavery, marking the earliest legal sanctioning of slavery in English colonies.

1641: Massachusetts legalizes slavery.

1650: Connecticut legalizes slavery.

1654: Virginia sanctions "the right of Negros to own slaves of their own race" after African Anthony Johnson, former indentured servant, sued to have fellow African John Casor declared not an indentured servant but "slave for life."

1661: Virginia officially recognizes slavery by statute.

1662: A Virginia statute declares that children born would have the same status as their mother.

1663: Maryland legalizes slavery.

1664: Slavery is legalized in New York and New Jersey.

1670: Carolina (later, South Carolina and North Carolina) is founded mainly by planters from the overpopulated British sugar island colony of Barbados, who brought relatively large numbers of African slaves from that island.

The shift from indentured servants to African slaves was prompted by a dwindling class of former servants who had worked through the terms of their indentures and thus became competitors to their former masters. These newly freed servants were rarely able to support themselves comfortably, and the tobacco industry was increasingly dominated by large planters. This caused domestic unrest culminating in Bacon's Rebellion. Eventually, chattel slavery became the norm in regions dominated by plantations.

Several local slave rebellions took place during the 17th and 18th centuries: Gloucester County, Virginia Revolt (1663); New York Slave Revolt of 1712; Stono Rebellion (1739); and New York Slave Insurrection of 1741.

Within the British Empire, the Massachusetts courts began to follow England when, in 1772, England became the first country in the world to outlaw the slave trade within its borders (see Somerset v Stewart) followed by the Knight v. Wedderburn decision in Scotland in 1778. Between 1764 and 1774, seventeen slaves appeared in Massachusetts courts to sue their owners for freedom. In 1766, John Adams' colleague Benjamin Kent won the first trial in the present-day United States to free a slave (Slew vs. Whipple).

The Republic of Vermont banned slavery in its constitution of 1777 and continued the ban when it entered the United States in 1791. Through the Northwest Ordinance of 1787 under the Congress of the Confederation, slavery was prohibited in the territories north west of the Ohio River. By 1804, abolitionists succeeded in passing legislation that ended legal slavery in every northern state (with slaves above a certain age legally transformed to indentured servants). Congress banned the international importation or export of slaves on 1 January 1808; but not the internal slave trade.

Despite the actions of abolitionists, free blacks were subject to racial segregation in the Northern states. While England did not ban slavery in present-day Canada until 1833, free blacks found refugee and liberty there after the America Revolution and again after the War of 1812. Slavery in Canada was largely ended by judicial court decisions by the early nineteenth century. Refugees from slavery fled the South across the Ohio River to the North via the Underground Railroad. Midwestern state governments asserted States Rights arguments to refuse federal jurisdiction over fugitives. Some juries exercised their right of jury nullification and refused to convict those indicted under the Fugitive Slave Act of 1850.

After the passage of the Kansas-Nebraska Act in 1854, armed conflict broke out in Kansas Territory, where the question of whether it would be admitted to the Union as a slave state or a free state had been left to the inhabitants. The radical abolitionist John Brown was active in the mayhem and killing in " Bleeding Kansas." The true turning point in public opinion is better fixed at the Lecompton Constitution fraud. Pro-slavery elements in Kansas had arrived first from Missouri and quickly organized a territorial government that excluded abolitionists. Through the machinery of the territory and violence, the pro-slavery faction attempted to force an unpopular pro-slavery constitution through the state. This infuriated Northern Democrats, who supported popular sovereignty, and was exacerbated by the Buchanan administration reneging on a promise to submit the constitution to a referendum-which would surely fail. Anti-slavery legislators took office under the banner of the newly formed Republican Party. The Supreme Court in the Dred Scott decision of 1857 asserted that one could take one's property anywhere, even if one's property was chattel and one crossed into a free territory. It also asserted that African Americans could not be federal citizens. Outraged critics across the North denounced these episodes as the latest of the Slave Power (the politically organized slave owners) taking more control of the nation.

The slave population in the United States stood at four million. Ninety-five percent of blacks lived in the South, comprising one third of the population there as opposed to 1% of the population of the North. The central issue in politics in the 1850s involved the extension of slavery into the western territories, which settlers from the Northern states opposed. The Whig Party split and collapsed on the slavery issue, to be replaced in the North by the new Republican Party, which was dedicated to stopping the expansion of slavery. Republicans gained a majority in every northern state by absorbing a faction of anti-slavery Democrats, and warning that slavery was a backward system that undercut democracy and economic modernization. Numerous compromise proposals were put forward, but they all collapsed. A majority of Northern voters were committed to stopping the expansion of slavery, which they believed would ultimately end slavery. Southern voters were overwhelmingly angry that they were being treated as second-class citizens. In the election of 1860, the Republicans swept Abraham Lincoln into the Presidency and his party took control (with only 39.8% of the popular vote) and legislators into Congress. The states of the deep South, convinced that the economic power of what they called " King Cotton" would overwhelm the North and win support from Europe voted to seceded from the U.S. (the Union). They formed the Confederate States of America, based on the promise of maintaining slavery. War broke out in April 1861, as both sides sought wave after wave of enthusiasm among young men volunteering to form new regiments and new armies. In the North, the main goal was to preserve the union as an expression of American nationalism.

By 1862 most northern leaders realized that the mainstay of Southern secession, slavery, had to be attacked head-on. All the border states rejected President Lincoln's proposal for compensated emancipation. However, by 1865 all had begun the abolition of slavery, except Kentucky and Delaware. The Emancipation Proclamation was an executive order issued by Lincoln on 1 January 1863. In a single stroke, it changed the legal status, as recognized by the U.S. government, of 3 million slaves in designated areas of the Confederacy from "slave" to "free." It had the practical effect that as soon as a slave escaped the control of the Confederate government, by running away or through advances of federal troops, the slave became legally and actually free. Plantation owners, realizing that emancipation would destroy their economic system, sometimes moved their slaves as far as possible out of reach of the Union army. By June 1865, the Union Army controlled all of the Confederacy and liberated all of the designated slaves. The owners were never compensated. Over 200,000 free blacks and newly freed slaves fought for the Union in the Army and Navy, thereby validating their claims to full citizenship.

The severe dislocations of war and Reconstruction had a severe negative impact on the black population, with a large amount of sickness and death. After liberation, many of the Freedmen remained on the same plantation. Others fled or crowded into refugee camps operated by the Freedmen's Bureau. The Bureau provided food, housing, clothing, medical care, church services, some schooling, legal support, and arranged for labor contracts. Fierce debates about the rights of the Freedmen, and of the defeated Confederates, often accompanied by killings of black leaders, marked the Reconstruction Era, 1863-77.

Slavery was never reestablished, but after 1877, white Democrats took control of all the southern states and blacks lost nearly all the political power they had achieved during Reconstruction. By 1900 they also lost the right to vote. They had become second class citizens. The great majority lived in the rural South in poverty working as laborers, sharecroppers or tenant farmers; a small proportion owned their own land. The black churches, especially the Baptist Church, was the center of community activity and leadership.

Slavery in the Middle East first developed out of the slavery practices of the Ancient Near East, and these practices were radically different at times, depending on social-political factors such as the Arab slave trade. Two rough estimates by scholars of the number of slaves held over twelve centuries in Muslim lands are 11.5 million and 14 million.

Under Sharia (Islamic law), children of slaves or prisoners of war could become slaves but only non-Muslims. Manumission of a slave was encouraged as a way of expiating sins. Many early converts to Islam, such as Bilal ibn Rabah al-Habashi, were the poor and former slaves. In theory, slavery in Islamic law does not have a racial or color component, although this has not always been the case in practice.

Bernard Lewis writes: "In one of the sad paradoxes of human history, it was the humanitarian reforms brought by Islam that resulted in a vast development of the slave trade inside, and still more outside, the Islamic empire." He notes that the Islamic injunctions against the enslavement of Muslims led to massive importation of slaves from the outside. According to Patrick Manning, Islam by recognizing and codifying the slavery seems to have done more to protect and expand slavery than the reverse.

Slavery was a legal and important part of the economy of the Ottoman Empire and Ottoman society until the slavery of Caucasians was banned in the early 19th century, although slaves from other groups were allowed. In Constantinople (present-day Istanbul), the administrative and political center of the Empire, about a fifth of the population consisted of slaves in 1609. Even after several measures to ban slavery in the late 19th century, the practice continued largely unfazed into the early 20th century. As late as 1908, female slaves were still sold in the Ottoman Empire. Sexual slavery was a central part of the Ottoman slave system throughout the history of the institution.

A member of the Ottoman slave class, called a in Turkish, could achieve high status. Harem guards and janissaries are some of the better-known positions a slave could hold, but slaves were actually often at the forefront of Ottoman politics. The majority of officials in the Ottoman government were bought slaves, raised free, and integral to the success of the Ottoman Empire from the 14th century into the 19th. Many officials themselves owned a large number of slaves, although the Sultan himself owned by far the largest amount. By raising and specially training slaves as officials in palace schools such as Enderun, the Ottomans created administrators with intricate knowledge of government and fanatic loyalty.

Ottomans practiced , a sort of "blood tax" or "child collection", young Christian boys from the Balkans and Anatolia were taken from their homes and families, brought up as Muslims, and enlisted into the most famous branch of the , the Janissaries, a special soldier class of the Ottoman army that became a decisive faction in the Ottoman invasions of Europe.

During the various 18th and 19th century persecution campaigns against Christians as well as during the culminating Assyrian, Armenian and Greek genocides of World War I, many indigenous Armenian, Assyrian and Greek Christian women and children were carried off as slaves by the Ottoman Turks and their Kurdish allies. Henry Morgenthau, Sr., U.S. Ambassador in Constantinople from 1913 to 1916, reports in his Ambassador Morgenthau's Story that there were gangs trading white slaves during his term in Constantinople. He also reports that Armenian girls were sold as slaves during the Armenian Genocide.

The Arab or Islamic slave trade lasted much longer than the Atlantic or European slave trade: "It began in the middle of the seventh century and survives today in Mauritania and Sudan. With the Islamic slave trade, we're talking of 14 centuries rather than four." Further, "whereas the gender ratio of slaves in the Atlantic trade was two males to every female, in the Islamic trade, it was two females to every male," according to Ronald Segal

According to media reports from late 2014 the Islamic State of Iraq and the Levant (ISIL) was selling Yazidi and Christian women as slaves. According to Haleh Esfandiari of the Woodrow Wilson International Center for Scholars, after ISIL militants have captured an area "[t]hey usually take the older women to a makeshift slave market and try to sell them." In mid-October 2014, the UN estimated that 5,000 to 7,000 Yazidi women and children were abducted by ISIL and sold into slavery. In the digital magazine , ISIL claimed religious justification for enslaving Yazidi women whom they consider to be from a heretical sect. ISIL claimed that the Yazidi are idol worshipers and their enslavement is part of the old shariah practice of spoils of war. According to The Wall Street Journal, ISIL appeals to apocalyptic beliefs and claims "justification by a Hadith that they interpret as portraying the revival of slavery as a precursor to the end of the world".

ISIL announced the revival of slavery as an institution. In 2015 the official slave prices set by ISIL were following:

Children aged 1 to 9 were sold for 200,000 dinars ($169).

Women and children 10 to 20 years old for 150,000 dinars ($127).

Women 20 to 30 years old for 100,000 dinar ($85).

Women 30 to 40 years old are 75,000 dinar ($63).

Women 40 to 50 years old for 50,000 dinar ($42).

However some slaves have been sold for as little as a pack of cigarettes. Sex slaves were sold to Saudi Arabia, other Persian Gulf states and Turkey.

Slavery has existed all throughout Asia, and forms of slavery still exist today.

Scholars differ as to whether or not slaves and the institution of slavery existed in ancient India. These English words have no direct, universally accepted equivalent in Sanskrit or other Indian languages, but some scholars translate the word , mentioned in texts like Manu Smriti, as slaves. Ancient historians who visited India offer the closest insights into the nature of Indian society and slavery in other ancient civilizations. For example, the Greek historian Arrian, who chronicled India about the time of Alexander the Great, wrote in his Indika,

The Indians do not even use aliens as slaves, much less a countryman of their own.

Qin dynasty (221-206 BC) Men sentenced to castration became eunuch slaves of the Qin dynasty state and as a result they were made to do forced labor, on projects like the Terracotta Army. The Qin government confiscated the property and enslaved the families of those who received castration as a punishment for rape.
Slaves were deprived of their rights and connections to their families.

Han dynasty (206 BC - 220 AD) One of Emperor Gao's first acts was to set free from slavery agricultural workers who were enslaved during the Warring States period, although domestic servants retained their status.

Men punished with castration during the Han dynasty were also used as slave labor.

Deriving from earlier Legalist laws, the Han dynasty set in place rules that the property of and families of criminals doing three years of hard labor or sentenced to castration were to have their families seized and kept as property by the government.

During the millennium long Chinese domination of Vietnam, Vietnam was a great source of slave girls who were used as sex slaves in China. The slave girls of Viet were even eroticized in Tang dynasty poetry.

The Islamic invasions, starting in the 8th century, also resulted in hundreds of thousands of Indians being enslaved by the invading armies, one of the earliest being the armies of the Umayyad commander Muhammad bin Qasim. Qutb-ud-din Aybak, a Turkic slave of Muhammad Ghori rose to power following his master's death. For almost a century, his descendants ruled North-Central India in form of Slave Dynasty. Several slaves were also brought to India by the Indian Ocean trades; for example, the Siddi are descendants of Bantu slaves brought to India by Arab and Portuguese merchants.

Andre Wink summarizes the slavery in 8th and 9th century India as follows,

(During the invasion of Muhammad al-Qasim), invariably numerous women and children were enslaved. The sources insist that now, in dutiful conformity to religious law, 'the one-fifth of the slaves and spoils' were set apart for the caliph's treasury and despatched to Iraq and Syria. The remainder was scattered among the army of Islam. At Rūr, a random 60,000 captives reduced to slavery. At Brahamanabad 30,000 slaves were allegedly taken. At Multan 6,000. Slave raids continued to be made throughout the late Umayyad period in Sindh, but also much further into Hind, as far as Ujjain and Malwa. The Abbasid governors raided Punjab, where many prisoners and slaves were taken.

In the early 11th century Tarikh al-Yamini, the Arab historian Al-Utbi recorded that in 1001 the armies of Mahmud of Ghazna conquered Peshawar and Waihand (capital of Gandhara) after Battle of Peshawar (1001), "in the midst of the land of Hindustan", and captured some 100,000 youths. Later, following his twelfth expedition into India in 1018-19, Mahmud is reported to have returned with such a large number of slaves that their value was reduced to only two to ten dirhams each. This unusually low price made, according to Al-Utbi, "merchants [come] from distant cities to purchase them, so that the countries of Central Asia, Iraq and Khurasan were swelled with them, and the fair and the dark, the rich and the poor, mingled in one common slavery". Elliot and Dowson refer to "five hundred thousand slaves, beautiful men and women.". Later, during the Delhi Sultanate period (1206-1555), references to the abundant availability of low-priced Indian slaves abound. Levi attributes this primarily to the vast human resources of India, compared to its neighbors to the north and west (India's Mughal population being approximately 12 to 20 times that of Turan and Iran at the end of the 16th century).

Slavery and empire-formation tied in particularly well with iqta and it is within this context of Islamic expansion that elite slavery was later commonly found. It became the predominant system in North India in the thirteenth century and retained considerable importance in the fourteenth century. Slavery was still vigorous in fifteenth-century Bengal, while after that date it shifted to the Deccan where it persisted until the seventeenth century. It remained present to a minor extent in the Mughal provinces throughout the seventeenth century and had a notable revival under the Afghans in North India again in the eighteenth century.

The Delhi sultanate obtained thousands of slaves and eunuch servants from the villages of Eastern Bengal (a widespread practice which Mughal emperor Jahangir later tried to stop). Wars, famines, pestilences drove many villagers to sell their children as slaves. The Muslim conquest of Gujarat in Western India had two main objectives. The conquerors demanded and more often forcibly wrested both land owned by Hindus and Hindu women. Enslavement of women invariably led to their conversion to Islam. In battles waged by Muslims against Hindus in Malwa and Deccan plateau, a large number of captives were taken. Muslim soldiers were permitted to retain and enslave POWs as plunder.

The first Bahmani sultan, Alauddin Bahman Shah is noted to have captured 1,000 singing and dancing girls from Hindu temples after he battled the northern Carnatic chieftains. The later Bahmanis also enslaved civilian women and children in wars; many of them were converted to Islam in captivity. About the Mughal empire, W.H. Moreland observed, "it became a fashion to raid a village or group of villages without any obvious justification, and carry off the inhabitants as slaves."

During the rule of Shah Jahan, many peasants were compelled to sell their women and children into slavery to meet the land revenue demand. Slavery was officially abolished in British India by the Indian Slavery Act, 1843. However, in modern India, Pakistan and Nepal, there are millions of bonded laborers, who work as slaves to pay off debts.

The Tang dynasty purchased Western slaves from the Radanite Jews. Tang Chinese soldiers and pirates enslaved Koreans, Turks, Persians, Indonesians, and people from Inner Mongolia, Central Asia, and northern India. The greatest source of slaves came from southern tribes, including Thais and aboriginals from the southern provinces of Fujian, Guangdong, Guangxi, and Guizhou. Malays, Khmers, Indians, and black Africans were also purchased as slaves in the Tang dynasty. Slavery was prevalent until the late 19th century and early 20th century China. All forms of slavery have been illegal in China since 1910.

Slavery in Japan was, for most of its history, indigenous, since the export and import of slaves was restricted by Japan being a group of islands. In late-16th-century Japan, slavery was officially banned; but forms of contract and indentured labor persisted alongside the period penal codes' forced labor. During the Second Sino-Japanese War and the Pacific War, the Japanese military used millions of civilians and prisoners of war from several countries as forced laborers.

In Korea, slavery was officially abolished with the Gabo Reform of 1894. During the Joseon period, in times of poor harvest and famine, many peasants voluntarily sold themselves into the nobi system in order to survive.

In Southeast Asia, there was a large slave class in Khmer Empire who built the enduring monuments in Angkor Wat and did most of the heavy work. Between the 17th and the early 20th centuries one-quarter to one-third of the population of some areas of Thailand and Burma were slaves. By the 19th century, Bhutan had developed a slave trade with Sikkim and Tibet, also enslaving British subjects and Brahmins. According to the International Labour Organization (ILO), during the early 21st century an estimated 800,000 people are subject to forced labor in Myanmar.

Slavery in pre-Spanish Philippines was practiced by the tribal Austronesian peoples who inhabited the culturally diverse islands. The neighbouring Muslim states conducted slave raids from the 1600s into the 1800s in coastal areas of the Gulf of Thailand and the Philippine islands. Slaves in Toraja society in Indonesia were family property. People would become slaves when they incurred a debt. Slaves could also be taken during wars, and slave trading was common. Torajan slaves were sold and shipped out to Java and Siam. Slaves could buy their freedom, but their children still inherited slave status. Slavery was abolished in 1863 in all Dutch colonies.

Records of slavery in Ancient Greece go as far back as Mycenaean Greece. The origins are not known, but it appears that slavery became an important part of the economy and society only after the establishment of cities. Slavery was common practice and an integral component of ancient Greece, as it was in other societies of the time, including ancient Israel. It is estimated that in Athens, the majority of citizens owned at least one slave. Most ancient writers considered slavery not only natural but necessary, but some isolated debate began to appear, notably in Socratic dialogues. The Stoics produced the first condemnation of slavery recorded in history.

During the 8th and the 7th centuries BC, in the course of the two Messenian Wars, the Spartans reduced an entire population to a pseudo-slavery called . According to Herodotus (IX, 28-29), helots were seven times as numerous as Spartans. Following several helot revolts around the year 600 BC, the Spartans restructured their city-state along authoritarian lines, for the leaders decided that only by turning their society into an armed camp could they hope to maintain control over the numerically dominant helot population. In some Ancient Greek city-states, about 30% of the population consisted of slaves, but paid and slave labor seem to have been equally important.

Romans inherited the institution of slavery from the Greeks and the Phoenicians. As the Roman Republic expanded outward, it enslaved entire populations, thus ensuring an ample supply of laborers to work in Rome's farms, quarries and households. The people subjected to Roman slavery came from all over Europe and the Mediterranean. Such oppression by an elite minority eventually led to slave revolts; the Third Servile War led by Spartacus was the most famous and severe. Greeks, Berbers, Germans, Britons, Slavs, Thracians, Gauls (or Celts), Jews, Arabs and many more ethnic groups were enslaved to be used for labor, and also for amusement (e.g. gladiators and sex slaves). If a slave ran away, they were liable to be crucified.

The overall impact of slavery on the Italian genetics was insignificant though, because the slaves imported in Italy were native Europeans, and very few if any of them had extra European origin. This has been further confirmed by recent biochemical analysis of 166 skeletons from three non-elite imperial-era cemeteries in the vicinity of Rome (where the bulk of the slaves lived), which shows that only 1 individual definitely came from outside of Europe (North Africa), and another 2 possibly did, but results are inconclusive. In the rest of the Italian peninsula, the amount of non European slaves was definitively much lower than that.

The chaos of invasion and frequent warfare also resulted in victorious parties taking slaves throughout Europe in the early Middle Ages. St. Patrick, himself captured and sold as a slave, protested against an attack that enslaved newly baptized Christians in his "Letter to the Soldiers of Coroticus". As a commonly traded commodity, like cattle, slaves could become a form of internal or trans-border currency. Slavery during the Early Middle Ages had several distinct sources.

The Vikings raided across Europe, but took the most slaves in raids on the British Isles and in Eastern Europe. While the Vikings kept some slaves as servants, known as , they sold most captives in the Byzantine or Islamic markets. In the West, their target populations were primarily English, Irish, and Scottish, while in the East they were mainly Slavs. The Viking slave-trade slowly ended in the 11th century, as the Vikings settled in the European territories they had once raided. They converted serfs to Christianity and themselves merged with the local populace.

In central Europe, specifically the Frankish/German/Holy Roman Empire of Charlemagne, raids and wars to the east generated a steady supply of slaves from the Slavic captives of these regions. Because of high demand for slaves in the wealthy Muslim empires of Northern Africa, Spain, and the Near East, especially for slaves of European descent, a market for these slaves rapidly emerged. So lucrative was this market that it spawned an economic boom in central and western Europe, today known as the Carolingian Renaissance. This boom period for slaves stretched from the early Muslim conquests to the High Middle Ages but declined in the later Middle Ages as the Islamic Golden Age waned.

Medieval Spain and Portugal saw almost constant warfare between Muslims and Christians. Al-Andalus sent periodic raiding expeditions to loot the Iberian Christian kingdoms, bringing back booty and slaves. In a raid against Lisbon, Portugal in 1189, for example, the Almohad caliph Yaqub al-Mansur took 3,000 female and child captives. In a subsequent attack upon Silves, Portugal in 1191, his governor of Córdoba took 3,000 Christian slaves.

The Byzantine-Ottoman wars and the Ottoman wars in Europe resulted in the taking of large numbers of Christian slaves and using or selling them in the Islamic world too. After the battle of Lepanto the victors freed approximately 12,000 Christian galley slaves from the Ottoman fleet.

Similarly, Christians sold Muslim slaves captured in war. The Order of the Knights of Malta attacked pirates and Muslim shipping, and their base became a centre for slave trading, selling captured North Africans and Turks. Malta remained a slave market until well into the late 18th century. One thousand slaves were required to man the galleys (ships) of the Order.

Poland banned slavery in the 15th century; in Lithuania, slavery was formally abolished in 1588; the institution was replaced by the second enserfment. Slavery remained a minor institution in Russia until 1723, when Peter the Great converted the household slaves into house serfs. Russian agricultural slaves were formally converted into serfs earlier, in 1679. The escaped Russian serfs and kholops formed autonomous communities in the southern steppes, where they became known as Cossacks (meaning "outlaws").

Capture in war, voluntary servitude and debt slavery became common within the British Isles before 1066. Slaves were routinely bought and sold. Running away was also common and slavery was never a major economic factor in the British Isles during the Middle Ages. Ireland and Denmark provided markets for captured Anglo-Saxon and Celtic slaves. Pope Gregory I reputedly made the pun, Non Angli, sed Angeli ("Not Angles, but Angels"), after a response to his query regarding the identity of a group of fair-haired Angles, slave children whom he had observed in the marketplace. After the Norman Conquest, the law no longer supported chattel slavery and slaves became part of the larger body of serfs.

Barbary pirates and Maltese corsairs both raided for slaves and purchased slaves from European merchants, often the Radhanites, one of the few groups who could easily move between the Christian and Islamic worlds.

In the late Middle Ages, from 1100 to 1500, the European slave-trade continued, though with a shift from being centered among the Western Mediterranean Islamic nations to the Eastern Christian and Muslim states. The city-states of Venice and Genoa controlled the Eastern Mediterranean from the 12th century and the Black Sea from the 13th century. They sold both Slavic and Baltic slaves, as well as Georgians, Turks, and other ethnic groups of the Black Sea and Caucasus. The sale of European slaves by Europeans slowly ended as the Slavic and Baltic ethnic groups Christianized by the Late Middle Ages. European slaves did not pass on an inherited status and was thus more akin to forced labor, or indentured servitude.

From the 1440s into the 18th century, Europeans from Italy, Spain, Portugal, France, and England were sold into slavery by North Africans, as described in the book "Christian Slaves, Muslim Masters". This same book states that "white slavery had been minimised or ignored because academics preferred to treat Europeans as evil colonialists rather than as victims." and likely overestimates the number of slaves taken. In 1575, the Tatars captured over 35,000 Ukrainians; a 1676 raid took almost 40,000. About 60,000 Ukrainians were captured in 1688; some were ransomed, but most were sold into slavery. Some of the Roma people were enslaved over five centuries in Romania until abolition in 1864 (see Slavery in Romania).

The Mongol invasions and conquests in the 13th century also resulted in taking numerous captives into slavery. The Mongols enslaved skilled individuals, women and children and marched them to Karakorum or Sarai, whence they were sold throughout Eurasia. Many of these slaves were shipped to the slave market in Novgorod.

Slave commerce during the Late Middle Ages was mainly in the hands of Venetian and Genoese merchants and cartels, who were involved in the slave trade with the Golden Horde. In 1382 the Golden Horde under Khan Tokhtamysh sacked Moscow, burning the city and carrying off thousands of inhabitants as slaves. Between 1414 and 1423, some 10,000 eastern European slaves were sold in Venice. Genoese merchants organized the slave trade from the Crimea to Mamluk Egypt. For years, the Khanates of Kazan and Astrakhan routinely made raids on Russian principalities for slaves and to plunder towns. Russian chronicles record about 40 raids by Kazan Khans on the Russian territories in the first half of the 16th century.

In 1441 Haci I Giray declared independence from the Golden Horde and established the Crimean Khanate. For a long time, until the early 18th century, the khanate maintained an extensive slave-trade with the Ottoman Empire and the Middle East. In a process called the "harvesting of the steppe" they enslaved many Slavic peasants. About 30 major Tatar raids were recorded into Muscovite territories between 1558 and 1596.

Moscow was repeatedly a target. In 1521, the combined forces of Crimean Khan Mehmed Giray and his Kazan allies attacked the city and captured thousands of slaves. In 1571, the Crimean Tatars attacked and sacked Moscow, burning everything but the Kremlin and taking thousands of captives as slaves. In Crimea, about 75% of the population consisted of slaves.

In the Viking era beginning circa 793, the Norse raiders often captured and enslaved militarily weaker peoples they encountered. The Nordic countries called their slaves ( Old Norse: Þræll). The thralls were mostly from Western Europe, among them many Franks, Frisians, Anglo-Saxons, and both Irish and Britonnic Celts. Many Irish slaves travelled in expeditions for the colonization of Iceland. The Norse also took German, Baltic, Slavic and Latin slaves. The slave trade was one of the pillars of Norse commerce during the 6th through 11th centuries. The 10th-century Persian traveller Ibn Rustah described how Swedish Vikings, the Varangians or Rus, terrorized and enslaved the Slavs taken in their raids along the Volga River. The thrall system was finally abolished in the mid-14th century in Scandinavia.

Mediterranean powers frequently sentenced convicted criminals to row in the war- galleys of the state (initially only in time of war). After the revocation of the Edict of Nantes in 1685 and Camisard rebellion, the French Crown filled its galleys with French Huguenots, Protestants condemned for resisting the state. Galley-slaves lived and worked in such harsh conditions that many did not survive their terms of sentence, even if they survived shipwreck and slaughter or torture at the hands of enemies or of pirates. Naval forces often turned 'infidel' prisoners-of-war into galley-slaves. Several well-known historical figures served time as galley slaves after being captured by the enemy-the Ottoman corsair and admiral Turgut Reis and the Knights Hospitaller Grand Master Jean Parisot de la Valette among them.

Denmark-Norway was the first European country to ban the slave trade. This happened with a decree issued by King Christian VII of Denmark in 1792, to become fully effective by 1803. Slavery as an institution was not banned until 1848. At this time Iceland was a part of Denmark-Norway but slave trading had been abolished in Iceland in 1117 and had never been reestablished.

Slavery in the French Republic was abolished on 4 February 1794, including in its colonies. The lengthy Haitian Revolution by its slaves and free people of color established Haiti as a free republic in 1804 ruled by blacks, the first of its kind. At the time of the revolution, Haiti was known as Saint-Domingue and was a colony of France. Napoleon Bonaparte gave up on Haiti in 1803, but re-established slavery in Guadeloupe and Martinique in 1804, at the request of planters of the Caribbean colonies. Slavery was permanently abolished in the French empire during the French Revolution of 1848.

The 15th-century Portuguese exploration of the African coast is commonly regarded as the harbinger of European colonialism. In 1452, Pope Nicholas V issued the papal bull Dum Diversas, granting Afonso V of Portugal the right to reduce any "Saracens, pagans and any other unbelievers" to hereditary slavery which legitimized slave trade under Catholic beliefs of that time. This approval of slavery was reaffirmed and extended in his Romanus Pontifex bull of 1455. These papal bulls came to serve as a justification for the subsequent era of the slave trade and European colonialism. Although for a short period as in 1462, Pius II declared slavery to be "a great crime". The followers of the church of England and Protestants did not use the papal bull as a justification. The position of the church was to condemn the slavery of Christians, but slavery was regarded as an old established and necessary institution which supplied Europe with the necessary workforce. In the 16th century, African slaves had replaced almost all other ethnicities and religious enslaved groups in Europe. Within the Portuguese territory of Brazil, and even beyond its original borders, the enslavement of Native Americans was carried out by the Bandeirantes.

Among many other European slave markets, Genoa, and Venice were some well-known markets, their importance and demand growing after the great plague of the 14th century which decimated much of the European workforce. The maritime town of Lagos, Portugal, was the first slave market created in Portugal for the sale of imported African slaves, the Mercado de Escravos, which opened in 1444. In 1441, the first slaves were brought to Portugal from northern Mauritania. Prince Henry the Navigator, major sponsor of the Portuguese African expeditions, as of any other merchandise, taxed one fifth of the selling price of the slaves imported to Portugal. By the year 1552 African slaves made up 10 percent of the population of Lisbon. In the second half of the 16th century, the Crown gave up the monopoly on slave trade and the focus of European trade in African slaves shifted from import to Europe to slave transports directly to tropical colonies in the Americas-in the case of Portugal, especially Brazil. In the 15th century, one-third of the slaves were resold to the African market in exchange of gold. Slavery was abolished in mainland Portugal and Portuguese India in 1761. It was finally abolished in all Portuguese colonies in 1869.

The Spaniards were the first Europeans to use African slaves in the New World on islands such as Cuba and Hispaniola, due to a shortage of labor caused by the spread of diseases, and so the Spanish colonists gradually became involved in the Atlantic slave trade. The first African slaves arrived in Hispaniola in 1501; by 1517, the natives had been "virtually annihilated" mostly to diseases. The problem of the justness of Native American's slavery was a key issue for the Spanish Crown. It was Charles V who gave a definite answer to this complicated and delicate matter. To that end, on 25 November 1542, the Emperor abolished slavery by decree in his Leyes Nuevas New Laws. This bill was based on the arguments given by the best Spanish theologists and jurists who were unanimous in the condemnation of such slavery as unjust; they declared it illegitimate and outlawed it from America-not just the slavery of Spaniards over Natives-but also the type of slavery practiced among the Natives themselves Thus, Spain became the first country to officially abolish slavery.

However, in the Spanish colonies of Cuba and Puerto Rico, where sugarcane production was highly profitable based on slave labor, African slavery persisted until 1873 in Puerto Rico "with provisions for periods of apprenticeship", and 1886 in Cuba.

Although slavery was illegal inside the Netherlands it flourished throughout the Dutch Empire in the Americas, Africa, Ceylon and Indonesia. The Dutch Slave Coast ( Dutch: Slavenkust) referred to the trading posts of the Dutch West India Company on the Slave Coast, which lie in contemporary Ghana, Benin, Togo and Nigeria. Initially the Dutch shipped slaves to northern Brazil, and during the second half of the 17th century they had a controlling interest in the trade to the Spanish colonies. Today's Suriname and Guyana became prominent markets in the 18th century. Between 1612 and 1872, the Dutch operated from some 10 fortresses along the Gold Coast (now Ghana), from which slaves were shipped across the Atlantic. Dutch involvement on the Slave Coast increased with the establishment of a trading post in Offra in 1660. Willem Bosman writes in his Nauwkeurige beschrijving van de Guinese Goud- Tand- en Slavekust (1703) that Allada was also called Grand Ardra, being the larger cousin of Little Ardra, also known as Offra. From 1660 onward, Dutch presence in Allada and especially Offra became more permanent. A report from this year asserts Dutch trading posts, apart from Allada and Offra, in Benin City, Grand-Popo, and Savi.

The Offra trading post soon became the most important Dutch office on the Slave Coast. According to a 1670 report, annually 2,500 to 3,000 slaves were transported from Offra to the Americas. These numbers were only feasible in times of peace, however, and dwindled in time of conflict. From 1688 onward, the struggle between the Aja king of Allada and the peoples on the coastal regions, impeded the supply of slaves. The Dutch West India Company chose the side of the Aja king, causing the Offra office to be destroyed by opposing forces in 1692. By 1650 the Dutch had the pre-eminent slave trade in Europe and South East Asia. Later, trade shifted to Ouidah. On the instigation of Governor-General of the Dutch Gold Coast Willem de la Palma, Jacob van den Broucke was sent in 1703 as "opperkommies" (head merchant) to the Dutch trading post at Ouidah, which according to sources was established around 1670. Political unrest caused the Dutch to abandon their trading post at Ouidah in 1725, and they then moved to Jaquim, at which place they built Fort Zeelandia. The head of the post, Hendrik Hertog, had a reputation for being a successful slave trader. In an attempt to extend his trading area, Hertog negotiated with local tribes and mingled in local political struggles. He sided with the wrong party, however, leading to a conflict with Director-General Jan Pranger and to his exile to the island of Appa in 1732. The Dutch trading post on this island was extended as the new centre of the slave trade. In 1733, Hertog returned to Jaquim, this time extending the trading post into Fort Zeelandia. The revival of the slave trade at Jaquim was only temporary, however, as his superiors at the Dutch West India Company noticed that Hertog's slaves were more expensive than at the Gold Coast. From 1735, Elmina became the preferred spot to trade slaves. As of 1778, it was estimated that the Dutch were shipping approximately 6,000 Africans for enslavement in the Dutch West Indies each year. Slavery also characterised the Dutch possessions in Indonesia, Ceylon and South Africa, where Indonesians have made a significant contribution to the Cape Coloured population of that country. The Dutch part in the Atlantic slave trade is estimated at 5-7 percent, as they shipped about 550,000-600,000 African slaves across the Atlantic, about 75,000 of whom died on board before reaching their destinations. From 1596 to 1829, the Dutch traders sold 250,000 slaves in the Dutch Guianas, 142,000 in the Dutch Caribbean islands, and 28,000 in Dutch Brazil. In addition, tens of thousands of slaves, mostly from India and some from Africa, were carried to the Dutch East Indies. The Netherlands was one of the last countries to abolish slavery in 1863. Although the decision was made in 1848, it took many years for the law to be implemented. Furthermore, slaves in Suriname would be fully free only in 1873, since the law stipulated that there was to be a mandatory 10-year transition.

Barbary Corsairs continued to trade in European slaves into the Modern time-period. Muslim pirates, primarily Algerians with the support of the Ottoman Empire, raided European coasts and shipping from the 16th to the 19th centuries, and took thousands of captives, whom they sold or enslaved. Many were held for ransom, and European communities raised funds such as Malta's Monte della Redenzione degli Schiavi to buy back their citizens. The raids gradually ended with the naval decline of the Ottoman Empire in the late 16th and 17th centuries, as well as the European conquest of North Africa throughout the 19th century.

From 1609 to 1616, England lost 466 merchant ships to Barbary pirates. 160 English ships were captured by Algerians between 1677 and 1680. Many of the captured sailors were made into slaves and held for ransom. The corsairs were no strangers to the South West of England where raids were known in a number of coastal communities. In 1627 Barbary Pirates under command of the Dutch renegade Jan Janszoon (Murat Reis), operating from the Moroccan port of Salé, occupied the island of Lundy. During this time there were reports of captured slaves being sent to Algiers.

Ireland, despite its northern position, was not immune from attacks by the corsairs. In June 1631 Janszoon, with pirates from Algiers and armed troops of the Ottoman Empire, stormed ashore at the little harbor village of Baltimore, County Cork. They captured almost all the villagers and took them away to a life of slavery in North Africa. The prisoners were destined for a variety of fates-some lived out their days chained to the oars as galley slaves, while others would spend long years in the scented seclusion of the harem or within the walls of the sultan's palace. Only two of them ever saw Ireland again.

The Congress of Vienna (1814-15), which ended the Napoleonic Wars, led to increased European consensus on the need to end Barbary raiding. The sacking of Palma on the island of Sardinia by a Tunisian squadron, which carried off 158 inhabitants, roused widespread indignation. Britain had by this time banned the slave trade and was seeking to induce other countries to do likewise. States that were more vulnerable to the corsairs complained that Britain cared more for ending the trade in African slaves than stopping the enslavement of Europeans and Americans by the Barbary States.

In order to neutralise this objection and further the anti-slavery campaign, in 1816 Britain sent Lord Exmouth to secure new concessions from Tripoli, Tunis, and Algiers, including a pledge to treat Christian captives in any future conflict as prisoners of war rather than slaves. He imposed peace between Algiers and the kingdoms of Sardinia and Sicily. On his first visit, Lord Exmouth negotiated satisfactory treaties and sailed for home. While he was negotiating, a number of Sardinian fishermen who had settled at Bona on the Tunisian coast were brutally treated without his knowledge. As Sardinians they were technically under British protection, and the government sent Exmouth back to secure reparation. On 17 August, in combination with a Dutch squadron under Admiral Van de Capellen, Exmouth bombarded Algiers. Both Algiers and Tunis made fresh concessions as a result.

The Barbary states had difficulty securing uniform compliance with a total prohibition of slave-raiding, as this had been traditionally of central importance to the North African economy. Slavers continued to take captives by preying on less well-protected peoples. Algiers subsequently renewed its slave-raiding, though on a smaller scale. Europeans at the Congress of Aix-la-Chapelle in 1818 discussed possible retaliation. In 1820 a British fleet under Admiral Sir Harry Neal bombarded Algiers. Corsair activity based in Algiers did not entirely cease until France conquered the state in 1830.

The Crimeans frequently mounted raids into the Danubian principalities, Poland-Lithuania, and Muscovy to enslave people whom they could capture; for each captive, the khan received a fixed share (savğa) of 10% or 20%. These campaigns by Crimean forces were either sefers ("sojourns" - officially declared military operations led by the khans themselves), or çapuls ("despoiling" - raids undertaken by groups of noblemen, sometimes illegally because they contravened treaties concluded by the khans with neighbouring rulers).

For a long time, until the early 18th century, the Crimean Khanate maintained a massive slave trade with the Ottoman Empire and the Middle East, exporting about 2 million slaves from Russia and Poland-Lithuania over the period 1500-1700. Caffa (modern Feodosia) became one of the best-known and significant trading ports and slave markets. In 1769 the last major Tatar raid saw the capture of 20,000 Russian and Ruthenian slaves.

Author and historian Brian Glyn Williams writes:

Fisher estimates that in the sixteenth century the Polish-Lithuanian Commonwealth lost around 20,000 individuals a year and that from 1474 to 1694, as many as a million Commonwealth citizens were carried off into Crimean slavery.

Early modern sources are full of descriptions of sufferings of Christian slaves captured by the Crimean Tatars in the course of their raids:

It seems that the position and everyday conditions of a slave depended largely on his/her owner. Some slaves indeed could spend the rest of their days doing exhausting labor: as the Crimean vizir (minister) Sefer Gazi Aga mentions in one of his letters, the slaves were often "a plough and a scythe" of their owners. Most terrible, perhaps, was the fate of those who became galley-slaves, whose sufferings were poeticized in many Ukrainian dumas (songs). ... Both female and male slaves were often used for sexual purposes.

Britain played a prominent role in the Atlantic slave trade, especially after 1640, when sugar cane was introduced to the region. At first, most were white Britons, or Irish, enslaved as indentured labour - for a fixed period - in the West Indies. These people may have been criminals, political rebels, the poor with no prospects or others who were simply tricked or kidnapped. Slavery was a legal institution in all of the 13 American colonies and Canada (acquired by Britain in 1763). The profits of the slave trade and of West Indian plantations amounted to 5% of the British economy at the time of the Industrial Revolution.

A little-known incident in the career of Judge Jeffreys refers to an assize in Bristol in 1685 when he made the mayor of the city, then sitting fully robed beside him on the bench, go into the dock and be fined £1000 for being a 'kidnapping knave'; some Bristol traders at the time were known at the time to kidnap their own countrymen and ship them away as slaves.

Somersett's case in 1772 was generally taken at the time to have decided that the condition of slavery did not exist under English law in England. In 1785, English poet William Cowper wrote: "We have no slaves at home - Then why abroad? Slaves cannot breathe in England; if their lungs receive our air, that moment they are free. They touch our country, and their shackles fall. That's noble, and bespeaks a nation proud. And jealous of the blessing. Spread it then, And let it circulate through every vein." However, slavery continued to thrive in England itself, much like it did in the British Empire, until full emancipation in the 1830s. In 1807, following many years of lobbying by the abolitionist movement, led primarily by William Wilberforce, the British Parliament voted to make the slave trade illegal anywhere in the Empire with the Slave Trade Act 1807. Thereafter Britain took a prominent role in combating the trade, and slavery itself was abolished in the British Empire (except for India) with the Slavery Abolition Act 1833. Between 1808 and 1860, the West Africa Squadron seized approximately 1,600 slave ships and freed 150,000 Africans who were aboard. Action was also taken against African leaders who refused to agree to British treaties to outlaw the trade. Akitoye, the 11th Oba of Lagos, is famous for having used British involvement to regain his rule in return for suppressing slavery among the Yoruba people of Lagos in 1851. Anti-slavery treaties were signed with over 50 African rulers. In 1839, the world's oldest international human rights organization, Anti-Slavery International, was formed in Britain by Joseph Sturge, which worked to outlaw slavery in other countries.

After 1833, the freed African slaves declined employment in the cane fields. This led to the importation of indentured labour again - mainly from India, and also China.

In 1811, Arthur William Hodge was executed for the murder of a slave in the British West Indies. He was not, however, as some have claimed, the first white person to have been lawfully executed for the murder of a slave.

During World War II Nazi Germany operated several categories of Arbeitslager (Labor Camps) for different categories of inmates. The largest number of them held Polish and Jewish civilians forcibly abducted in the occupied countries (see Łapanka) to provide labor in the German war industry, repair bombed railroads and bridges or work on farms. By 1944, 20% of all workers were foreigners, either civilians or prisoners of war.

This is not classed as slavery per se, as defined in the first paragraph, i.e. slavery under this definition does not include other forced labour systems, such as historical forced labor by prisoners, labor camps, or other forms of unfree labor, in which labourers are not legally considered property. Slavery typically requires a shortage of labor and a surplus of land to be viable.

As agreed by the Allies at the Yalta conference Germans were used as forced labor as part of the reparations to be extracted. By 1947 it is estimated that 400,000 Germans (both civilians and POWs) were being used as forced labor by the U.S., France, the UK and the Soviet Union. German prisoners were for example forced to clear minefields in France and the Low Countries. By December 1945 it was estimated by French authorities that 2,000 German prisoners were being killed or injured each month in accidents. In Norway the last available casualty record, from 29 August 1945, shows that by that time a total of 275 German soldiers died while clearing mines, while 392 had been injured. Death rates for the German civilians doing forced labor in the Soviet Union ranged between 19% and 39%, depending on category.

In the first half of the 19th century, small-scale slave raids took place across Polynesia to supply labor and sex workers for the whaling and sealing trades, with examples from both the westerly and easterly extremes of the Polynesian triangle. By the 1860s this had grown to a larger scale operation with Peruvian slave raids in the South Sea Islands to collect labor for the guano industry.

Ancient Hawaii was a caste society. People were born into specific social classes. Kauwa were those of the outcast or slave class. They are believed to have been war captives, or the descendants of war captives. Marriage between higher castes and the kauwa was strictly forbidden. The kauwa worked for the chiefs and were often used as human sacrifices at the luakini heiau. (They were not the only sacrifices; law-breakers of all castes or defeated political opponents were also acceptable as victims.)

The kapu system was abolished during the ʻAi Noa in 1819, and with it the distinction between the kauwā slave class and the makaʻāinana (commoners). The 1852 Constitution of the Kingdom of Hawaii officially made slavery illegal.

Before the arrival of European settlers, each Maori tribe () considered itself a separate entity equivalent to a nation. In traditional Maori society of Aotearoa, prisoners of war became taurekareka, slaves, unless released, ransomed or eaten. With some exceptions, the child of a slave remained a slave.

As far as it is possible to tell, slavery seems to have increased in the early 19th century with increased numbers of prisoners being taken by Māori military leaders, such as Hongi Hika and Te Rauparaha to satisfy the need for labor in the Musket Wars, to supply whalers and traders with food, flax and timber in return for western goods. The intertribal Musket Wars lasted 1807 to 1843 when large numbers of slaves were captured by northern tribes who had acquired muskets. About 20,000 Maori died in the wars which were concentrated in the North Island. An unknown number of slaves were captured. Northern tribes used slaves (called mokai) to grow large areas of potatoes for trade with visiting ships. Chiefs started an extensive sex trade in the Bay of Islands in the 1830s using mainly slave girls. By 1835 about 70-80 ships per year called into the port. One French captain described the impossibility of getting rid of the girls who swarmed over his ship outnumbering his crew of 70 by 3 to 1. All payments to the girls were stolen by the chief. By 1833 Christianity had become established in the north and large numbers of slaves were freed. However two Taranaki tribes, Ngati Tama and Ngati Mutunga, displaced by the wars carried out a carefully planned invasion of the Chatham Islands, 800 km east of Christchurch, in 1835. About 15% of the Polynesian Moriori natives who had migrated to the islands at about 1500 CE were killed, with many women being tortured to death. The remaining population was enslaved for the purpose of growing food, especially potatoes. The Moriori were treated in an inhumane and degrading manner for many years. Their culture was banned and they were forbidden to marry. Slavery was outlawed when the British entered into a constitutional arrangement with New Zealand in 1840 via the Treaty of Waitangi, although it did not end completely until government was effectively extended over the whole of the country with the defeat of the Kingi movement in the Wars of the mid-1860s.

Some Maori took Moriori partners. The state of enslavement of Moriori lasted until the 1860s although it had been discouraged by CMS missionaries in North New Zealand from the late 1820s. In 1870 Ngati Mutunga, one of the invading tribes, argued before the Native Land Court in New Zealand that their gross mistreatment of the Moriori was standard Maori practice or tikanga.

One group of Polynesians who migrated to the Chatham Islands became the Moriori who developed a largely pacifist culture. It was originally speculated that they settled the Chathams direct from Polynesia, but it is now widely believed they were disaffected Maori who emigrated from the South Island of New Zealand. Their pacifism left the Moriori unable to defend themselves when the islands were invaded by mainland Māori in the 1830s. Two Taranaki tribes, Ngati Tama and Ngati Mutunga, displaced by the musket wars, carried out a carefully planned invasion of the Chatham Islands, 800 km east of Christchurch, in 1835. About 15% of the Polynesian Moriori natives who had migrated to the islands at about 1500 CE were killed, with many women being tortured to death. The remaining population was enslaved for the purpose of growing food, especially potatoes. The Moriori were treated in an inhumane and degrading manner for many years. Their culture was banned and they were forbidden to marry. Slavery was outlawed when the British annexed New Zealand in 1840, immediately prior to the signing of the Treaty of Waitangi, although it did not end completely until government was effectively extended over the whole of the country with the defeat of the Kingi movement in the Wars of the mid-1860s.

Some 300 Moriori men, women and children were massacred and the remaining 1,200 to 1,300 survivors were enslaved.

Rapa Nui / Easter Island

The isolated island of Rapa Nui/ Easter Island was inhabited by the Rapanui, who suffered a series of slave raids from 1805 or earlier, culminating in a near genocidal experience in the 1860s. The 1805 raid was by American sealers and was one of a series that changed the attitude of the islanders to outside visitors, with reports in the 1820s and 1830s that all visitors received a hostile reception. In December 1862, Peruvian slave raiders took between 1,400 and 2,000 islanders back to Peru to work in the guano industry; this was about a third of the island's population and included much of the island's leadership, the last ariki-mau and possibly the last who could read Rongorongo. After intervention by the French ambassador in Lima, the last 15 survivors were returned to the island, but brought with them smallpox, which further devastated the island.

Slavery has existed, in one form or another, throughout the whole of human history. So, too, have movements to free large or distinct groups of slaves. However, abolitionism should be distinguished from efforts to help a particular group of slaves, or to restrict one practice, such as the slave trade.

Although there were numerous slave revolts in the Caribbean, the only successful uprising came in the French colony of Haiti in the 1790s, where the slaves rose up, killed the mulattoes and whites, and established the independent Republic of Haiti. Europe recoiled in horror.

Cyrus the Great, the founder of Persian Empire prohibited the systematic enslavement of conquered non-combatant population. Cyrus also freed slaves and allowed all deported peoples who were enslaved by preceding Assyrian and Babylonian kings, to return home. It is said that he freed up to 40,000 Jews and allowed them to return home. Cylinder of Cyrus the Great containing the Decree on the conquered non-combatant population.

In 1772, the Somersett Case (R. v. Knowles, ex parte Somersett) of the English Court of King's Bench ruled that it was unlawful for a slave to be forcibly taken abroad. The case has since been misrepresented as finding that slavery was unlawful in England (although not elsewhere in the British Empire). A similar case, that of Joseph Knight, took place in Scotland five years later and ruled slavery to be contrary to the law of Scotland.

Following the work of campaigners in the United Kingdom, such as William Wilberforce and Thomas Clarkson, the Act for the Abolition of the Slave Trade was passed by Parliament on 25 March 1807, coming into effect the following year. The act imposed a fine of £100 for every slave found aboard a British ship. The intention was to outlaw entirely the Atlantic slave trade within the whole British Empire.

The significance of the abolition of the British slave trade lay in the number of people hitherto sold and carried by British slave vessels. Britain shipped 2,532,300 Africans across the Atlantic, equalling 41% of the total transport of 6,132,900 individuals. This made the British empire the biggest slave-trade contributor in the world due to the magnitude of the empire, which made the abolition act all the more damaging to the global trade of slaves. Britain used its diplomatic influence to press other nations into treaties to ban their slave trade and to give the Royal Navy the right to interdict slave ships sailing under their national flag.

The Slavery Abolition Act, passed on 1 August 1833, outlawed slavery itself throughout the British Empire, with the exception of India. On 1 August 1834 slaves became indentured to their former owners in an apprenticeship system for six years. Full emancipation was granted ahead of schedule on 1 August 1838. Britain abolished slavery in both Hindu and Muslim India with the Indian Slavery Act, 1843.

Domestic slavery practised by the educated African coastal elites (as well as interior traditional rulers) in Sierra Leone was abolished in 1928. A study found practices of domestic slavery still widespread in rural areas in the 1970s.

There were slaves in mainland France (especially in trade ports such as Nantes or Bordeaux)., but the institution was never officially authorized there. The legal case of Jean Boucaux in 1739 clarified the unclear legal position of possible slaves in France, and was followed by laws that established registers for slaves in mainland France, who were limited to a three-year stay, for visits or learning a trade. Unregistered "slaves" in France were regarded as free. However, slavery was of vital importance in France's Caribbean possessions, especially Saint-Domingue.

In 1793, influenced by the French Declaration of the Rights of Man of August 1789 and alarmed as the massive slave revolt of August 1791 that had become the Haitian Revolution threatened to ally itself with the British, the French Revolutionary commissioners Sonthonax and Polverel declared general emancipation to reconcile them with France. In Paris, on 4 February 1794, Abbé Grégoire and the Convention ratified this action by officially abolishing slavery in all French territories outside mainland France, freeing all the slaves both for moral and security reasons.

Napoleon came to power in 1799 and soon had grandiose plans for the French sugar colonies; to achieve them he reintroduced slavery. Napoleon's major adventure into the Caribbean-sending 30,000 troops in 1802 to retake Saint Domingue (Haiti) from ex-slaves under Toussaint L'Ouverture who had revolted. Napoleon wanted to preserve France's financial benefits from the colony's sugar and coffee crops; he then planned to establish a major base at New Orleans. He therefore re-established slavery in Haiti and Guadeloupe, where it had been abolished after rebellions. Slaves and black freedmen fought the French for their freedom and independence. Revolutionary ideals played a central role in the fighting for it was the slaves and their allies who were fighting for the revolutionary ideals of freedom and equality, while the French troops under General Charles Leclerc fought to restore the order of the ancien régime. The goal of re-establishing slavery explicitly contradicted the ideals of the French Revolution. The French soldiers were unable to cope with the tropical diseases, and most died of yellow fever. Slavery was reimposed in Guadeloupe but not in Haiti, which became an independent black republic. Napoleon's vast colonial dreams for Egypt, India, the Caribbean, Louisiana, and even Australia were all doomed for lack of a fleet capable of matching Britain's Royal Navy. Realizing the fiasco Napoleon liquidated the Haiti project, brought home the survivors and sold off the huge Louisiana territory to the US in 1803.

In 1794 slavery was abolished in the French Empire. After seizing Lower Egypt in 1798, Napoleon Bonaparte issued a proclamation in Arabic, declaring all men to be free and equal. However, the French bought males as soldiers and females as concubines. Napoleon personally opposed the abolition and restored colonial slavery in 1802, a year after the capitulation of his troops in Egypt.

Victor Schœlcher and the 1848 abolition

The American Colonization Society, the primary vehicle for returning black Americans to greater freedom in Africa, established the colony of Liberia in 1821-23, on the premise that former American slaves would have greater freedom and equality there. The ACS assisted in the movement of thousands of African Americans to Liberia, with its founder Henry Clay stating; "unconquerable prejudice resulting from their color, they never could amalgamate with the free whites of this country. It was desirable, therefore, as it respected them, and the residue of the population of the country, to drain them off". Abraham Lincoln, an enthusiastic supporter of Clay, adopted his position on returning the blacks to their own land.

Slaves in the United States who escaped ownership would often make their way to Canada via the " Underground Railroad". The more famous of the African American abolitionists include former slaves Harriet Tubman, Sojourner Truth and Frederick Douglass. Many more people who opposed slavery and worked for abolition were northern whites, such as William Lloyd Garrison and John Brown. Slavery was legally abolished in 1865 by the Thirteenth Amendment to the United States Constitution.

While abolitionists agreed on the evils of slavery, there were differing opinions on what should happen after African Americans were freed. By the time of Emancipation, African-Americans were now native to the United States and did not want to leave. Most believed that their labor had made the land theirs as well as that of the whites.

The Declaration of the Powers, on the Abolition of the Slave Trade, of 8 February 1815 (Which also formed ACT, No. XV. of the Final Act of the Congress of Vienna of the same year) included in its first sentence the concept of the "principles of humanity and universal morality" as justification for ending a trade that was "odious in its continuance".

The 1926 Slavery Convention, an initiative of the League of Nations, was a turning point in banning global slavery. Article 4 of the Universal Declaration of Human Rights, adopted in 1948 by the UN General Assembly, explicitly banned slavery. The United Nations 1956 Supplementary Convention on the Abolition of Slavery was convened to outlaw and ban slavery worldwide, including child slavery. In December 1966, the UN General Assembly adopted the International Covenant on Civil and Political Rights, which was developed from the Universal Declaration of Human Rights. Article 4 of this international treaty bans slavery. The treaty came into force in March 1976 after it had been ratified by 35 nations.

As of November 2003, 104 nations had ratified the treaty. However, illegal forced labour involves millions of people in the 21st century, 43% for sexual exploitation and 32% for economic exploitation.

In May 2004, the 22 members of the Arab League adopted the Arab Charter on Human Rights, which incorporated the 1990 Cairo Declaration on Human Rights in Islam, which states:

Human beings are born free, and no one has the right to enslave, humiliate, oppress or exploit them, and there can be no subjugation but to God the Most-High.

-  Article 11, Cairo Declaration on Human Rights in Islam, 1990

Currently, the Anti-trafficking Coordination Team Initiative (ACT Team Initiative), a coordinated effort between the U.S. departments of justice, homeland security and labor, addresses human trafficking. The International Labour Organization estimates that there are 20.9 million victims of human trafficking globally, including 5.5 million children, of which 55% are women and girls.

The history of slavery originally was the history of the government's laws and policies toward slavery, and the political debates about it. Black history was promoted very largely at black colleges. The situation changed dramatically with the coming of the Civil Rights Movement of the 1950s. Attention shifted to the enslaved humans, the free blacks, and the struggles of the black community against adversity.

Peter Kolchin described the state of historiography in the early 20th century as follows:

During the first half of the twentieth century, a major component of this approach was often simply racism, manifest in the belief that blacks were, at best, imitative of whites. Thus Ulrich B. Phillips, the era's most celebrated and influential expert on slavery, combined a sophisticated portrait of the white planters' life and behavior with crude passing generalizations about the life and behavior of their black slaves.

Historians James Oliver Horton and Lois E. Horton described Phillips' mindset, methodology and influence:

His portrayal of blacks as passive, inferior people, whose African origins made them uncivilized, seemed to provide historical evidence for the theories of racial inferiority that supported racial segregation. Drawing evidence exclusively from plantation records, letters, southern newspapers, and other sources reflecting the slaveholder's point of view, Phillips depicted slave masters who provided for the welfare of their slaves and contended that true affection existed between master and slave.

Their account of the era rested, as one member of the Dunning school put it, on the assumption of "negro incapacity." Finding it impossible to believe that blacks could ever be independent actors on the stage of history, with their own aspirations and motivations, Dunning et al. portrayed African Americans either as "children", ignorant dupes manipulated by unscrupulous whites, or as savages, their primal passions unleashed by the end of slavery.

In the portrayal of the slave as a victim, the historian Stanley M. Elkins in his 1959 work Slavery: A Problem in American Institutional and Intellectual Life compared the effects of United States slavery to that resulting from the brutality of the Nazi concentration camps. He stated the institution destroyed the will of the slave, creating an "emasculated, docile Sambo" who identified totally with the owner. Elkins' thesis was challenged by historians. Gradually historians recognized that in addition to the effects of the owner-slave relationship, slaves did not live in a "totally closed environment but rather in one that permitted the emergence of enormous variety and allowed slaves to pursue important relationships with persons other than their master, including those to be found in their families, churches and communities."

Economic historians Robert W. Fogel and Stanley L. Engerman in the 1970s, through their work Time on the Cross, portrayed slaves as having internalized the Protestant work ethic of their owners. In portraying the more benign version of slavery, they also argue in their 1974 book that the material conditions under which the slaves lived and worked compared favorably to those of free workers in the agriculture and industry of the time. (This was also an argument of Southerners during the 19th century.)

In the 1970s and 1980s, historians made use of sources such as black music and statistical census data to create a more detailed and nuanced picture of slave life. Relying also on 19th-century autobiographies of ex-slaves (known as slave narratives) and the WPA Slave Narrative Collection, a set of interviews conducted with former slaves in the 1930s by the Federal Writers' Project, historians described slavery as the slaves remembered it. Far from slaves' being strictly victims or content, historians showed slaves as both resilient and autonomous in many of their activities. Despite their exercise of autonomy and their efforts to make a life within slavery, current historians recognize the precariousness of the slave's situation. Slave children quickly learned that they were subject to the direction of both their parents and their owners. They saw their parents disciplined just as they came to realize that they also could be physically or verbally abused by their owners. Historians writing during this era include John Blassingame ( Slave Community), Eugene Genovese ( Roll, Jordan, Roll), Leslie Howard Owens ( This Species of Property), and Herbert Gutman ( The Black Family in Slavery and Freedom).

Important work on slavery has continued; for instance, in 2003 Steven Hahn published the Pulitzer Prize-winning account, A Nation under Our Feet: Black Political Struggles in the Rural South from Slavery to the Great Migration, which examined how slaves built community and political understanding while enslaved, so they quickly began to form new associations and institutions when emancipated, including black churches separate from white control. In 2010, Robert E. Wright published a model that explains why slavery was more prevalent in some areas than others (e.g. southern than northern Delaware) and why some firms (individuals, corporations, plantation owners) chose slave labor while others used wage, indentured, or family labor instead.

Historical revisionism arrived when West Indian historian Eric Williams, a Marxist, in Capitalism and Slavery (1944), rejected this moral explanation and argued that abolition was now more profitable, for a century of sugarcane raising had exhausted the soil of the islands, and the plantations had become unprofitable. It was more profitable to sell the slaves to the government than to keep up operations. The 1807 prohibition of the international trade, Williams argued, prevented French expansion on other islands. Meanwhile, British investors turned to Asia, where labor was so plentiful that slavery was unnecessary. Williams went on to argue that slavery played a major role in making Britain prosperous. The high profits from the slave trade, he said, helped finance the Industrial Revolution. Britain enjoyed prosperity because of the capital gained from the unpaid work of slaves.

Since the 1970s numerous historians have challenged Williams from various angles and Gad Heuman has concluded, "More recent research has rejected this conclusion; it is now clear that the colonies of the British Caribbean profited considerably during the Revolutionary and Napoleonic Wars." In his major attack on the Williams's thesis, Seymour Drescher argues that Britain's abolition of the slave trade in 1807 resulted not from the diminishing value of slavery for Britain but instead from the moral outrage of the British voting public. Critics have also argued that slavery remained profitable in the 1830s because of innovations in agriculture so the profit motive was not central to abolition. Richardson (1998) finds Williams's claims regarding the Industrial Revolution are exaggerated, for profits from the slave trade amounted to less than 1% of domestic investment in Britain. Richardson further challenges claims (by African scholars) that the slave trade caused widespread depopulation and economic distress in Africa-indeed that it caused the "underdevelopment" of Africa. Admitting the horrible suffering of slaves, he notes that many Africans benefited directly because the first stage of the trade was always firmly in the hands of Africans. European slave ships waited at ports to purchase cargoes of people who were captured in the hinterland by African dealers and tribal leaders. Richardson finds that the "terms of trade" (how much the ship owners paid for the slave cargo) moved heavily in favor of the Africans after about 1750. That is, indigenous elites inside West and Central Africa made large and growing profits from slavery, thus increasing their wealth and power.

Economic historian Stanley Engerman finds that even without subtracting the associated costs of the slave trade (e.g., shipping costs, slave mortality, mortality of British people in Africa, defense costs) or reinvestment of profits back into the slave trade, the total profits from the slave trade and of West Indian plantations amounted to less than 5% of the British economy during any year of the Industrial Revolution. Engerman's 5% figure gives as much as possible in terms of benefit of the doubt to the Williams argument, not solely because it does not take into account the associated costs of the slave trade to Britain, but also because it carries the full-employment assumption from economics and holds the gross value of slave trade profits as a direct contribution to Britain's national income. Historian Richard Pares, in an article written before Williams's book, dismisses the influence of wealth generated from the West Indian plantations upon the financing of the Industrial Revolution, stating that whatever substantial flow of investment from West Indian profits into industry there was occurred after emancipation, not before.

The history of slavery spans many cultures, nationalities, and religions from ancient times to the present day. However the social, economic, and legal positions of slaves have differed vastly in different systems of slavery in different times and places.

Slavery occurs relatively rarely among hunter-gatherer populations because it develops under conditions of social stratification. Slavery operated in the very first civilizations (such as Sumer in Mesopotamia, which dates back as far as 3500 BCE). Slavery features in the Mesopotamian Code of Hammurabi (c. 1860 BCE), which refers to it as an established institution. Slavery became common within much of Europe during the Early Middle Ages and it continued into the following centuries. The Byzantine-Ottoman wars (1265-1479) and the Ottoman wars in Europe (14th to 20th centuries) resulted in the capture of large numbers of Christian slaves. The Dutch, French, Spanish, Portuguese, British, Arabs and a number of West African kingdoms played a prominent role in the Atlantic slave trade, especially after 1600. The Republic of Ragusa became the first European country to ban the slave trade in 1416. In modern times Denmark-Norway abolished the trade in 1802.

Although slavery is no longer legal anywhere in the world (with the exception of penal labour), human trafficking remains an international problem and an estimated 25-40 million people were enslaved as of 2013, the majority in Asia. During the 1983-2005 Second Sudanese Civil War people were taken into slavery. Evidence emerged in the late 1990s of systematic child-slavery and -trafficking on cacao plantations in West Africa. Slavery continues into the 21st century. Although Mauritania criminalized slavery in August 2007, an estimated up to 600,000 men, women and children, or 20% of the population of Mauritania, are currently enslaved, many of them used as bonded labor. Slavery in the 21st century continues, with the top ten countries with the highest prevalence according to the Global Slavery Index being North Korea, Eritrea, Burundi, the Central African Republic, Afghanistan, Mauritania, South Sudan, Pakistan, Cambodia and Iran. Islamist quasi-states such as the Islamic State of Iraq and the Levant and Boko Haram have abducted and enslaved women and children (often to serve as sex slaves).

Evidence of slavery predates written records, and has existed in many cultures. Mass slavery requires economic surpluses and a high population density to be viable. Due to these factors, the practice of slavery would have only proliferated after the invention of agriculture during the Neolithic Revolution, about 11,000 years ago.

C. 1480 BCE, fugitive slave treaty between Idrimi of Alakakh (now Tell Atchana) and Pillia of Kizzuwatna (now Cilicia).

French historian Fernand Braudel noted that slavery was endemic in Africa and part of the structure of everyday life. "Slavery came in different guises in different societies: there were court slaves, slaves incorporated into princely armies, domestic and household slaves, slaves working on the land, in industry, as couriers and intermediaries, even as traders". During the 16th century, Europe began to outpace the Arab world in the export traffic, with its slave traffic from Africa to the Americas. The Dutch imported slaves from Asia into their colony in South Africa. In 1807 Britain, which held extensive, although mainly coastal, colonial territories on the African continent (including southern Africa), made the international slave trade illegal, as did the United States in 1808.

Slavery in Ethiopia persisted until 1942. The Anti-Slavery Society estimated that there were 2,000,000 slaves in the early 1930s, out of an estimated population of between 8 and 16 million. It was finally abolished by order of emperor Haile Selassie on 26 August 1942.

When British rule was first imposed on the Sokoto Caliphate and the surrounding areas in northern Nigeria at the turn of the 20th century, approximately 2 million to 2.5 million people there were slaves. Slavery in northern Nigeria was finally outlawed in 1936.

Elikia M'bokolo, April 1998, Le Monde diplomatique. Quote: "The African continent was bled of its human resources via all possible routes. Across the Sahara, through the Red Sea, from the Indian Ocean ports and across the Atlantic. At least ten centuries of slavery for the benefit of the Muslim countries (from the ninth to the nineteenth)." He continues: "Four million slaves exported via the Red Sea, another four million through the Swahili ports of the Indian Ocean, perhaps as many as nine million along the trans-Saharan caravan route, and eleven to twenty million (depending on the author) across the Atlantic Ocean"

Zanzibar was once East Africa's main slave-trading port, and under Omani Arabs in the 19th century, as many as 50,000 slaves were passing through the city each year.

Prior to the 16th century, the bulk of slaves exported from Africa were shipped from East Africa to the Arabian peninsula. Zanzibar became a leading port in this trade. Arab slave traders differed from European ones in that they would often conduct raiding expeditions themselves, sometimes penetrating deep into the continent. They also differed in that their market greatly preferred the purchase of female slaves over male ones.

The increased presence of European rivals along the East coast led Arab traders to concentrate on the overland slave caravan routes across the Sahara from the Sahel to North Africa. The German explorer Gustav Nachtigal reported seeing slave caravans departing from Kukawa in Bornu bound for Tripoli and Egypt in 1870. The slave trade represented the major source of revenue for the state of Bornu as late as 1898. The eastern regions of the Central African Republic have never recovered demographically from the impact of 19th-century raids from the Sudan and still have a population density of less than 1 person/km². During the 1870s, European initiatives against the slave trade caused an economic crisis in northern Sudan, precipitating the rise of Mahdist forces. Mahdi's victory created an Islamic state, one that quickly reinstituted slavery.

The Middle Passage, the crossing of the Atlantic to the Americas, endured by slaves laid out in rows in the holds of ships, was only one element of the well-known triangular trade engaged in by Portuguese, Dutch, Danish-Norwegians, French, British and others. Ships having landed slaves in Caribbean ports would take on sugar, indigo, raw cotton, and later coffee, and make for Liverpool, Nantes, Lisbon or Amsterdam. Ships leaving European ports for West Africa would carry printed cotton textiles, some originally from India, copper utensils and bangles, pewter plates and pots, iron bars more valued than gold, hats, trinkets, gunpowder and firearms and alcohol. Tropical shipworms were eliminated in the cold Atlantic waters, and at each unloading, a profit was made.

While talking about the slave trade in East Africa in his journals, "To overdraw its evil is a simple impossibility."

To overdraw its evil is a simple impossibility.

David Livingstone while travelling in the African Great Lakes Region in 1866 described a trail of slaves as such:

19th June 1866 - We passed a woman tied by the neck to a tree and dead, the people of the country explained that she had been unable to keep up with the other slaves in a gang, and her master had determined that she should not become anyone's property if she recovered.
26th June. - ...We passed a slave woman shot or stabbed through the body and lying on the path: a group of men stood about a hundred yards off on one side, and another of the women on the other side, looking on; they said an Arab who passed early that morning had done it in anger at losing the price he had given for her, because she was unable to walk any longer.
27th June 1866 - To-day we came upon a man dead from starvation, as he was very thin. One of our men wandered and found many slaves with slave-sticks on, abandoned by their masters from want of food; they were too weak to be able to speak or say where they had come from; some were quite young.

The strangest disease I have seen in this country seems really to be broken-heartedness, and it attacks free men who have been captured and made slaves... Twenty one were unchained, as now safe; however all ran away at once; but eight with many others still in chains, died in three days after the crossing. They described their only pain in the heart, and placed the hand correctly on the spot, though many think the organ stands high up in the breast-bone.

African states played a role in the slave trade, and slavery was a common practice among Sub Saharan Africans before the involvement of the Arabs, Berbers and Europeans. There were three types: those who were slaves through conquest, those who were slaves due to unpaid debts, or those whose parents gave them as slaves to tribal chiefs. Chieftains would barter their slaves to Arab, Berber, Ottoman or European buyers for rum, spices, cloth or other goods. Selling captives or prisoners was commonly practiced among Africans, Turks, Berbers and Arabs during that era. However, as the Atlantic slave trade increased its demand, local systems which primarily serviced indentured servitude expanded. European slave trading, as a result, was the most pivotal change in the social, economic, cultural, spiritual, religious, political dynamics of the concept of slave trading. It ultimately undermined local economies and political stability as villages' vital labour forces were shipped overseas as slave raids and civil wars became commonplace. Crimes which were previously punishable by some other means became punishable by enslavement.

The kings of Dahomey sold their war captives into transatlantic slavery, who otherwise may have been killed in a ceremony known as the Annual Customs. As one of West Africa's principal slave states, Dahomey became extremely unpopular with neighbouring peoples. Like the Bambara Empire to the east, the Khasso kingdoms depended heavily on the slave trade for their economy. A family's status was indicated by the number of slaves it owned, leading to wars for the sole purpose of taking more captives. This trade led the Khasso into increasing contact with the European settlements of Africa's west coast, particularly the French. Benin grew increasingly rich during the 16th and 17th centuries on the slave trade with Europe; slaves from enemy states of the interior were sold, and carried to the Americas in Dutch and Portuguese ships. The Bight of Benin's shore soon came to be known as the "Slave Coast".

The slave trade is the ruling principle of my people. It is the source and the glory of their wealth...the mother lulls the child to sleep with notes of triumph over an enemy reduced to slavery...

In 1807, under internal and external pressures, the United Kingdom made illegal the international trade in slaves. The Royal Navy was deployed to prevent slavers from the United States, France, Spain, Portugal, Holland, West Africa and Arabia. The King of Bonny (now in Nigeria) allegedly became dissatisfied of the British intervention in stopping slave trading.

We think this trade must go on. That is the verdict of our oracle and the priests. They say that your country, however great, can never stop a trade ordained by God himself.

Joseph Miller states that African buyers would prefer males, but in reality, women and children would be more easily captured as men fled. Those captured would be sold for various reasons such as food, debts, or servitude. Once captured, the journey to the coast killed many and weakened others. Disease engulfed many, and insufficient food damaged those who made it to the coasts. Scurvy was so common that it was known as mal de Luanda (Luanda sickness). The assumption for those who died on the journey died from malnutrition. As food was limited, water may have been just as bad. Dysentery was widespread and poor sanitary conditions at ports did not help. Since supplies were poor, slaves were not equipped with the best clothing that further exposed to more diseases.

If the fear of disease caused terror, the psyche of slaves for being captured was just as terrifying. The most popular assumption for being captured was Europeans were cannibals. Stories and rumours spread that whites captured Africans to eat them. Olaudah Equiano accounts his experience about the sorrow slaves encountered at the ports. He talks about his first moment on a slave ship and asked if he was going to be eaten. Yet, the worst for slaves has only begun, and the journey on the water proved to be more terrifying. For every 100 Africans captured, only 64 would reach the coast, and only about 50 would reach the New World.

Others believe that slavers had a vested interest in capturing rather than killing, and in keeping their captives alive; and that this coupled with the disproportionate removal of males and the introduction of new crops from the Americas ( cassava, maize) would have limited general population decline to particular regions of western Africa around 1760-1810, and in Mozambique and neighbouring areas half a century later. There has also been speculation that within Africa, females were most often captured as brides, with their male protectors being a "bycatch" who would have been killed if there had not been an export market for them.

British explorer Mungo Park encountered a group of slaves when traveling through Mandinka country:

They were all very inquisitive, but they viewed me at first with looks of horror, and repeatedly asked if my countrymen were cannibals. They were very desirous to know what became of the slaves after they had crossed the salt water. I told them that they were employed in cultivation the land; but they would not believe me ... A deeply-rooted idea that the whites purchase negroes for the purpose of devouring them, or of selling them to others that they may be devoured hereafter, naturally makes the slaves contemplate a journey towards the coast with great terror, insomuch that the slatees are forced to keep them constantly in irons, and watch them very closely, to prevent their escape.

During the period from the late 19th century and early 20th century, demand for the labour-intensive harvesting of rubber drove frontier expansion and forced labour. The personal monarchy of Belgian King Leopold II in the Congo Free State saw mass killings and slavery to extract rubber.

Stephanie Smallwood in her book Saltwater Slavery uses Equiano's account on board ships to describe the general thoughts of most slaves.

Then," said I, "how comes it in all our country we never heard of them?" They told me because they lived so very far off. I then asked where were their women? Had they any like themselves? I was told that they had. "And why," said I, "do we not see them?" They answered, because they were left behind. I asked how the vessel could go? They told me they could not tell; but that there was cloth put upon the masts by the help of the ropes I saw, and then the vessel went on; and the white men had some spell or magic they put in the water when they liked, in order to stop the vessel. I was exceedingly amazed at this account, and really thought they were spirits. I there-fore wished much to be from amongst them, for I expected they would sacrifice me; but my wishes were vain-for we were so quartered that it was impossible for any of us to make our escape.

Accounts like these raised many questions as some slaves grew philosophical with their journey. Smallwood points out the challenges for slaves were physical and metaphysical. The physical would be obvious as the challenge to overcome capacity, lack of ship room, and food. The metaphysical was unique as the open sea would challenge African slaves' vision of the ocean as habitable. At essence, the journey on the ocean would prove to be an African's biggest fear that would keep them in awe. Combining this with the lack of knowledge of the sea, Africans would be entering a world of anxiety never seen before. Yet, Europeans were also fearful of the sea, but not to the extent of Africans. One of these dilemmas came with the sense of time. Africans used seasonal weather to predict time and days. The moon was a sense of time, but used like in other cultures. On the sea, Africans used the moon to best count the days, but the sea did not provide seasonal changes for them to know how long they were at sea. Counting the days on a ship was not the main priority, however. Surviving the voyage was the main horror. No one escaped diseases as the close quarters infected everyone including the crew. Death was so common that ships were called tumbeiros or floating tombs. What shocked Africans the most was how death was handled in the ships. Smallwood says the traditions for an African death was delicate and community-based. On ships, bodies would be thrown into the sea. Because the sea represented bad omens, bodies in the sea represented a form of purgatory and the ship a form of hell. In the end, the Africans who made the journey would have survived disease, malnutrition, confined space, close death, and the trauma of the ship.

In Algiers during the time of the Regency of Algiers in North Africa in the 19th century, 1.5 million Christians and Europeans were captured and forced into slavery. This eventually led to the Bombardment of Algiers in 1816 by the British and Dutch, forcing the Dey of Algiers to free many slaves.

The trading of children has been reported in modern Nigeria and Benin. In parts of Ghana, a family may be punished for an offense by having to turn over a virgin female to serve as a sex slave within the offended family. In this instance, the woman does not gain the title or status of "wife". In parts of Ghana, Togo, and Benin, shrine slavery persists, despite being illegal in Ghana since 1998. In this system of ritual servitude, sometimes called trokosi (in Ghana) or voodoosi in Togo and Benin, young virgin girls are given as slaves to traditional shrines and are used sexually by the priests in addition to providing free labor for the shrine.

An article in the Middle East Quarterly in 1999 reported that slavery is endemic in Sudan. Estimates of abductions during the Second Sudanese Civil War range from 14,000 to 200,000 people.

During the Second Sudanese Civil War people were taken into slavery; estimates of abductions range from 14,000 to 200,000. Abduction of Dinka women and children was common. In Mauritania it is estimated that up to 600,000 men, women and children, or 20% of the population, are currently enslaved, many of them used as bonded labor. Slavery in Mauritania was criminalized in August 2007.

During the Darfur conflict that began in 2003, many people were kidnapped by Janjaweed and sold into slavery as agricultural labor, domestic servants and sex slaves.

In Niger, slavery is also a current phenomenon. A Nigerien study has found that more than 800,000 people are enslaved, almost 8% of the population. Niger installed an anti-slavery provision in 2003. In a landmark ruling in 2008, the ECOWAS Community Court of Justice declared that the Republic of Niger failed to protect Hadijatou Mani Koraou from slavery, and awarded Mani CFA 10,000,000 (approximately US$20,000) in reparations.

Sexual slavery and forced labor are common in the Democratic Republic of Congo.

Many pygmies in the Republic of Congo and Democratic Republic of Congo belong from birth to Bantus in a system of slavery.

Evidence emerged in the late 1990s of systematic slavery in cacao plantations in West Africa; see the chocolate and slavery article.

On the night of 14-15 April 2014, a group of militants attacked the Government Girls Secondary School in Chibok, Nigeria. They broke into the school, pretending to be guards, telling the girls to get out and come with them. A large number of students were taken away in trucks, possibly into the Konduga area of the Sambisa Forest where Boko Haram were known to have fortified camps. Houses in Chibok were also burned down in the incident. According to police, approximately 276 children were taken in the attack, of whom 53 had escaped as of 2 May. Other reports said that 329 girls were kidnapped, 53 had escaped and 276 were still missing. The students have been forced to convert to Islam and into marriage with members of Boko Haram, with a reputed " bride price" of ₦2,000 each ($12.50/ £7.50). Many of the students were taken to the neighbouring countries of Chad and Cameroon, with sightings reported of the students crossing borders with the militants, and sightings of the students by villagers living in the Sambisa Forest, which is considered a refuge for Boko Haram.

On 5 May 2014 a video in which Boko Haram leader Abubakar Shekau claimed responsibility for the kidnappings emerged. Shekau claimed that "Allah instructed me to sell them...I will carry out his instructions" and "[s]lavery is allowed in my religion, and I shall capture people and make them slaves." He said the girls should not have been in school and instead should have been married since girls as young as nine are suitable for marriage.

During the Second Libyan Civil War Libyans started capturing some of the Sub-Saharan African migrants trying to get to Europe through Libya and selling them on slave markets. Slaves are often ransomed to their families and in the meantime until ransom can be paid, they may be tortured, forced to work, sometimes worked to death, and eventually they may be executed or left to starve if the payment has not been made after a period of time. Women are often raped and used as sex slaves and sold to brothels.

Many child migrants also suffer from abuse and child rape in Libya.

In Pre-Columbian Mesoamerica the most common forms of slavery were those of prisoners of war and debtors. People unable to pay back debts could be sentenced to work as slaves to the persons owed until the debts were worked off. Warfare was important to Maya society, because raids on surrounding areas provided the victims required for human sacrifice, as well as slaves for the construction of temples. Most victims of human sacrifice were prisoners of war or slaves. Slavery was not usually hereditary; children of slaves were born free. In the Inca Empire, workers were subject to a in lieu of taxes which they paid by working for the government. Each , or extended family, would decide which family member to send to do the work. It is unclear if this labor draft or corvée counts as slavery. The Spanish adopted this system, particularly for their silver mines in Bolivia.

Other slave-owning societies and tribes of the New World were, for example, the Tehuelche of Patagonia, the Comanche of Texas, the Caribs of Dominica, the Tupinambá of Brazil, the fishing societies, such as the Yurok, that lived along the coast from what is now Alaska to California, the Pawnee and Klamath. Many of the indigenous peoples of the Pacific Northwest Coast, such as the Haida and Tlingit, were traditionally known as fierce warriors and slave-traders, raiding as far as California. Slavery was hereditary, the slaves being prisoners of war. Among some Pacific Northwest tribes about a quarter of the population were slaves. One slave narrative was composed by an Englishman, John R. Jewitt, who had been taken alive when his ship was captured in 1802; his memoir provides a detailed look at life as a slave, and asserts that a large number were held.

During the period from the late 19th century and early 20th century, demand for the labor-intensive harvesting of rubber drove frontier expansion and slavery in Latin America and elsewhere. Indigenous peoples were enslaved as part of the rubber boom in Ecuador, Peru, Colombia, and Brazil. In Central America, rubber tappers participated in the enslavement of the indigenous Guatuso-Maleku people for domestic service.

Slavery was a mainstay of the Brazilian colonial economy, especially in mining and sugarcane production. 35.3% of all slaves involved in the Atlantic Slave trade went to Brazil. 4 million slaves were obtained by Brazil, 1.5 million more than any other country. Starting around 1550, the Portuguese began to trade African slaves to work the sugar plantations, once the native Tupi people deteriorated. Although Portuguese Prime Minister Sebastião José de Carvalho e Melo, 1st Marquis of Pombal abolished slavery in mainland Portugal on 12 February 1761, slavery continued in her overseas colonies. Slavery was practiced among all classes. Slaves were owned by upper and middle classes, by the poor, and even by other slaves.

From São Paulo, the Bandeirantes, adventurers mostly of mixed Portuguese and native ancestry, penetrated steadily westward in their search for Indian slaves. Along the Amazon river and its major tributaries, repeated slaving raids and punitive attacks left their mark. One French traveler in the 1740s described hundreds of miles of river banks with no sign of human life and once-thriving villages that were devastated and empty. In some areas of the Amazon Basin, and particularly among the Guarani of southern Brazil and Paraguay, the Jesuits had organized their Jesuit Reductions along military lines to fight the slavers. In the mid-to-late 19th century, many Amerindians were enslaved to work on rubber plantations.

Escaped slaves formed Maroon communities which played an important role in the histories of Brazil and other countries such as Suriname, Puerto Rico, Cuba, and Jamaica. In Brazil, the Maroon villages were called palenques or quilombos. Maroons survived by growing vegetables and hunting. They also raided plantations. At these attacks, the maroons would burn crops, steal livestock and tools, kill slavemasters, and invite other slaves to join their communities.

Jean-Baptiste Debret, a French painter who was active in Brazil in the first decades of the 19th century, started out with painting portraits of members of the Brazilian Imperial family, but soon became concerned with the slavery of both blacks and indigenous inhabitants. His paintings on the subject (two appear on this page) helped bring attention to the subject in both Europe and Brazil itself.

The Clapham Sect, a group of evangelical reformers, campaigned during much of the 19th century for Britain to use its influence and power to stop the traffic of slaves to Brazil. Besides moral qualms, the low cost of slave-produced Brazilian sugar meant that British colonies in the West Indies were unable to match the market prices of Brazilian sugar, and each Briton was consuming 16 pounds (7 kg) of sugar a year by the 19th century. This combination led to intensive pressure from the British government for Brazil to end this practice, which it did by steps over several decades.

Brazil's 1877-78 Grande Seca (Great Drought) in the cotton-growing northeast led to major turmoil, starvation, poverty and internal migration. As wealthy plantation holders rushed to sell their slaves south, popular resistance and resentment grew, inspiring numerous emancipation societies. They succeeded in banning slavery altogether in the province of Ceará by 1884. Slavery was legally ended nationwide on 13 May by the ("Golden Law") of 1888. It was an institution in decadence at these times, as since the 1880s the country had begun to use European immigrant labor instead. Brazil was the last nation in the Western Hemisphere to abolish slavery.

Slavery was commonly used in the parts of the Caribbean controlled by France and the British Empire. The Lesser Antilles islands of Barbados, St. Kitts, Antigua, Martinique and Guadeloupe, which were the first important slave societies of the Caribbean, began the widespread use of African slaves by the end of the 17th century, as their economies converted from sugar production.

England had multiple sugar islands in the Caribbean, especially Jamaica, Barbados, Nevis, and Antigua, which provided a steady flow of sugar sales; slave labor produced the sugar. By the 1700s, there were more slaves in Barbados than all the colonies combined. Since Barbados did not have many mountains, the British were able to clear land for sugar cane. Indentured servants were initially sent to Barbados to work in the sugar fields. These indentured servants were treated so poorly that future indentured servants stopped going to Barbados, and there were not enough people to work the fields. This is when the British started bringing in African slaves. It was important for the slaves to be in Barbados because sugar had become a necessity for most people and the demand for it was high.

An important result of Britain's victory in the War of the Spanish Succession (1702-1714) was enlarging its role in the slave trade. Of special importance was the successful secret negotiation with France to obtain thirty-year monopoly on the Spanish slave trade, called the Queen Anne of Great Britain also allowed her North American colonies like Virginia to make laws that promoted black slavery. Anne had secretly negotiated with France to get its approval regarding the Asiento. She boasted to Parliament of her success in taking the Asiento away from France and London celebrated her economic coup. Most of the slave trade involved sales to Spanish colonies in the Caribbean, and to Mexico, as well as sales to British colonies in the Caribbean and in North America. Historian Vinita Ricks says the agreement allotted Queen Anne "22.5% (and King Philip V, of Spain 28%) of all profits collected for her personal fortune." Ricks concludes that the Queen's "connection to slave trade revenue meant that she was no longer a neutral observer. She had a vested interest in what happened on slave ships."

By 1778, the French were importing approximately 13,000 Africans for enslavement yearly to the French West Indies.

To regularise slavery, in 1685 Louis XIV had enacted the , which accorded certain human rights to slaves and responsibilities to the master, who was obliged to feed, clothe and provide for the general well-being of his slaves. Free blacks owned one-third of the plantation property and one-quarter of the slaves in Saint Domingue (later Haiti). Slavery in the French First Republic was abolished on 4 February 1794. When it became clear that Napoleon intended to re-establish slavery in Haiti, Dessalines and Pétion switched sides, in October 1802. On 1 January 1804, Jean-Jacques Dessalines, the new leader under the dictatorial 1801 constitution, declared Haiti a free republic. Thus Haiti became the second independent nation in the Western Hemisphere, after the United States, and the only successful slave rebellion in world history.

Whitehall in England announced in 1833 that slaves in its territories would be totally freed by 1840. In the meantime, the government told slaves they had to remain on their plantations and would have the status of "apprentices" for the next six years.

In Port-of-Spain, Trinidad, on 1 August 1834, an unarmed group of mainly elderly Negroes being addressed by the Governor at Government House about the new laws, began chanting: "Pas de six ans. Point de six ans" ("Not six years. No six years"), drowning out the voice of the Governor. Peaceful protests continued until a resolution to abolish apprenticeship was passed and de facto freedom was achieved. Full emancipation for all was legally granted ahead of schedule on 1 August 1838, making Trinidad the first British colony with slaves to completely abolish slavery.

In late August 1619, the frigate , a privateer ship owned by Robert Rich, 2nd Earl of Warwick, but flying a Dutch flag arrived at Point Comfort, Virginia (several miles downstream from the colony of Jamestown, Virginia) with the first recorded slaves from Africa to Virginia. The approximately 20 Africans were from the present-day Angola. They had been removed by the White Lion's crew from a Portuguese slave ship, the São João Bautista.

Only a fraction of the enslaved Africans brought to the New World came to British North America, perhaps as little as 5% of the total. The vast majority of slaves were sent to the Caribbean sugar colonies, Brazil, or Spanish America.

By the 1680s, with the consolidation of England's Royal African Company, enslaved Africans were arriving in English colonies in larger numbers, and the institution continued to be protected by the British government. Colonists now began purchasing slaves in larger numbers.

1640: Virginia courts sentence John Punch to lifetime slavery, marking the earliest legal sanctioning of slavery in English colonies.

1641: Massachusetts legalizes slavery.

1650: Connecticut legalizes slavery.

1654: Virginia sanctions "the right of Negros to own slaves of their own race" after African Anthony Johnson, former indentured servant, sued to have fellow African John Casor declared not an indentured servant but "slave for life."

1661: Virginia officially recognizes slavery by statute.

1662: A Virginia statute declares that children born would have the same status as their mother.

1663: Maryland legalizes slavery.

1664: Slavery is legalized in New York and New Jersey.

1670: Carolina (later, South Carolina and North Carolina) is founded mainly by planters from the overpopulated British sugar island colony of Barbados, who brought relatively large numbers of African slaves from that island.

The shift from indentured servants to African slaves was prompted by a dwindling class of former servants who had worked through the terms of their indentures and thus became competitors to their former masters. These newly freed servants were rarely able to support themselves comfortably, and the tobacco industry was increasingly dominated by large planters. This caused domestic unrest culminating in Bacon's Rebellion. Eventually, chattel slavery became the norm in regions dominated by plantations.

Several local slave rebellions took place during the 17th and 18th centuries: Gloucester County, Virginia Revolt (1663); New York Slave Revolt of 1712; Stono Rebellion (1739); and New York Slave Insurrection of 1741.

Within the British Empire, the Massachusetts courts began to follow England when, in 1772, England became the first country in the world to outlaw the slave trade within its borders (see Somerset v Stewart) followed by the Knight v. Wedderburn decision in Scotland in 1778. Between 1764 and 1774, seventeen slaves appeared in Massachusetts courts to sue their owners for freedom. In 1766, John Adams' colleague Benjamin Kent won the first trial in the present-day United States to free a slave (Slew vs. Whipple).

The Republic of Vermont banned slavery in its constitution of 1777 and continued the ban when it entered the United States in 1791. Through the Northwest Ordinance of 1787 under the Congress of the Confederation, slavery was prohibited in the territories north west of the Ohio River. By 1804, abolitionists succeeded in passing legislation that ended legal slavery in every northern state (with slaves above a certain age legally transformed to indentured servants). Congress banned the international importation or export of slaves on 1 January 1808; but not the internal slave trade.

Despite the actions of abolitionists, free blacks were subject to racial segregation in the Northern states. While England did not ban slavery in present-day Canada until 1833, free blacks found refugee and liberty there after the America Revolution and again after the War of 1812. Slavery in Canada was largely ended by judicial court decisions by the early nineteenth century. Refugees from slavery fled the South across the Ohio River to the North via the Underground Railroad. Midwestern state governments asserted States Rights arguments to refuse federal jurisdiction over fugitives. Some juries exercised their right of jury nullification and refused to convict those indicted under the Fugitive Slave Act of 1850.

After the passage of the Kansas-Nebraska Act in 1854, armed conflict broke out in Kansas Territory, where the question of whether it would be admitted to the Union as a slave state or a free state had been left to the inhabitants. The radical abolitionist John Brown was active in the mayhem and killing in " Bleeding Kansas." The true turning point in public opinion is better fixed at the Lecompton Constitution fraud. Pro-slavery elements in Kansas had arrived first from Missouri and quickly organized a territorial government that excluded abolitionists. Through the machinery of the territory and violence, the pro-slavery faction attempted to force an unpopular pro-slavery constitution through the state. This infuriated Northern Democrats, who supported popular sovereignty, and was exacerbated by the Buchanan administration reneging on a promise to submit the constitution to a referendum-which would surely fail. Anti-slavery legislators took office under the banner of the newly formed Republican Party. The Supreme Court in the Dred Scott decision of 1857 asserted that one could take one's property anywhere, even if one's property was chattel and one crossed into a free territory. It also asserted that African Americans could not be federal citizens. Outraged critics across the North denounced these episodes as the latest of the Slave Power (the politically organized slave owners) taking more control of the nation.

The slave population in the United States stood at four million. Ninety-five percent of blacks lived in the South, comprising one third of the population there as opposed to 1% of the population of the North. The central issue in politics in the 1850s involved the extension of slavery into the western territories, which settlers from the Northern states opposed. The Whig Party split and collapsed on the slavery issue, to be replaced in the North by the new Republican Party, which was dedicated to stopping the expansion of slavery. Republicans gained a majority in every northern state by absorbing a faction of anti-slavery Democrats, and warning that slavery was a backward system that undercut democracy and economic modernization. Numerous compromise proposals were put forward, but they all collapsed. A majority of Northern voters were committed to stopping the expansion of slavery, which they believed would ultimately end slavery. Southern voters were overwhelmingly angry that they were being treated as second-class citizens. In the election of 1860, the Republicans swept Abraham Lincoln into the Presidency and his party took control (with only 39.8% of the popular vote) and legislators into Congress. The states of the deep South, convinced that the economic power of what they called " King Cotton" would overwhelm the North and win support from Europe voted to seceded from the U.S. (the Union). They formed the Confederate States of America, based on the promise of maintaining slavery. War broke out in April 1861, as both sides sought wave after wave of enthusiasm among young men volunteering to form new regiments and new armies. In the North, the main goal was to preserve the union as an expression of American nationalism.

By 1862 most northern leaders realized that the mainstay of Southern secession, slavery, had to be attacked head-on. All the border states rejected President Lincoln's proposal for compensated emancipation. However, by 1865 all had begun the abolition of slavery, except Kentucky and Delaware. The Emancipation Proclamation was an executive order issued by Lincoln on 1 January 1863. In a single stroke, it changed the legal status, as recognized by the U.S. government, of 3 million slaves in designated areas of the Confederacy from "slave" to "free." It had the practical effect that as soon as a slave escaped the control of the Confederate government, by running away or through advances of federal troops, the slave became legally and actually free. Plantation owners, realizing that emancipation would destroy their economic system, sometimes moved their slaves as far as possible out of reach of the Union army. By June 1865, the Union Army controlled all of the Confederacy and liberated all of the designated slaves. The owners were never compensated. Over 200,000 free blacks and newly freed slaves fought for the Union in the Army and Navy, thereby validating their claims to full citizenship.

The severe dislocations of war and Reconstruction had a severe negative impact on the black population, with a large amount of sickness and death. After liberation, many of the Freedmen remained on the same plantation. Others fled or crowded into refugee camps operated by the Freedmen's Bureau. The Bureau provided food, housing, clothing, medical care, church services, some schooling, legal support, and arranged for labor contracts. Fierce debates about the rights of the Freedmen, and of the defeated Confederates, often accompanied by killings of black leaders, marked the Reconstruction Era, 1863-77.

Slavery was never reestablished, but after 1877, white Democrats took control of all the southern states and blacks lost nearly all the political power they had achieved during Reconstruction. By 1900 they also lost the right to vote. They had become second class citizens. The great majority lived in the rural South in poverty working as laborers, sharecroppers or tenant farmers; a small proportion owned their own land. The black churches, especially the Baptist Church, was the center of community activity and leadership.

Slavery in the Middle East first developed out of the slavery practices of the Ancient Near East, and these practices were radically different at times, depending on social-political factors such as the Arab slave trade. Two rough estimates by scholars of the number of slaves held over twelve centuries in Muslim lands are 11.5 million and 14 million.

Under Sharia (Islamic law), children of slaves or prisoners of war could become slaves but only non-Muslims. Manumission of a slave was encouraged as a way of expiating sins. Many early converts to Islam, such as Bilal ibn Rabah al-Habashi, were the poor and former slaves. In theory, slavery in Islamic law does not have a racial or color component, although this has not always been the case in practice.

Bernard Lewis writes: "In one of the sad paradoxes of human history, it was the humanitarian reforms brought by Islam that resulted in a vast development of the slave trade inside, and still more outside, the Islamic empire." He notes that the Islamic injunctions against the enslavement of Muslims led to massive importation of slaves from the outside. According to Patrick Manning, Islam by recognizing and codifying the slavery seems to have done more to protect and expand slavery than the reverse.

Slavery was a legal and important part of the economy of the Ottoman Empire and Ottoman society until the slavery of Caucasians was banned in the early 19th century, although slaves from other groups were allowed. In Constantinople (present-day Istanbul), the administrative and political center of the Empire, about a fifth of the population consisted of slaves in 1609. Even after several measures to ban slavery in the late 19th century, the practice continued largely unfazed into the early 20th century. As late as 1908, female slaves were still sold in the Ottoman Empire. Sexual slavery was a central part of the Ottoman slave system throughout the history of the institution.

A member of the Ottoman slave class, called a in Turkish, could achieve high status. Harem guards and janissaries are some of the better-known positions a slave could hold, but slaves were actually often at the forefront of Ottoman politics. The majority of officials in the Ottoman government were bought slaves, raised free, and integral to the success of the Ottoman Empire from the 14th century into the 19th. Many officials themselves owned a large number of slaves, although the Sultan himself owned by far the largest amount. By raising and specially training slaves as officials in palace schools such as Enderun, the Ottomans created administrators with intricate knowledge of government and fanatic loyalty.

Ottomans practiced , a sort of "blood tax" or "child collection", young Christian boys from the Balkans and Anatolia were taken from their homes and families, brought up as Muslims, and enlisted into the most famous branch of the , the Janissaries, a special soldier class of the Ottoman army that became a decisive faction in the Ottoman invasions of Europe.

During the various 18th and 19th century persecution campaigns against Christians as well as during the culminating Assyrian, Armenian and Greek genocides of World War I, many indigenous Armenian, Assyrian and Greek Christian women and children were carried off as slaves by the Ottoman Turks and their Kurdish allies. Henry Morgenthau, Sr., U.S. Ambassador in Constantinople from 1913 to 1916, reports in his Ambassador Morgenthau's Story that there were gangs trading white slaves during his term in Constantinople. He also reports that Armenian girls were sold as slaves during the Armenian Genocide.

The Arab or Islamic slave trade lasted much longer than the Atlantic or European slave trade: "It began in the middle of the seventh century and survives today in Mauritania and Sudan. With the Islamic slave trade, we're talking of 14 centuries rather than four." Further, "whereas the gender ratio of slaves in the Atlantic trade was two males to every female, in the Islamic trade, it was two females to every male," according to Ronald Segal

According to media reports from late 2014 the Islamic State of Iraq and the Levant (ISIL) was selling Yazidi and Christian women as slaves. According to Haleh Esfandiari of the Woodrow Wilson International Center for Scholars, after ISIL militants have captured an area "[t]hey usually take the older women to a makeshift slave market and try to sell them." In mid-October 2014, the UN estimated that 5,000 to 7,000 Yazidi women and children were abducted by ISIL and sold into slavery. In the digital magazine , ISIL claimed religious justification for enslaving Yazidi women whom they consider to be from a heretical sect. ISIL claimed that the Yazidi are idol worshipers and their enslavement is part of the old shariah practice of spoils of war. According to The Wall Street Journal, ISIL appeals to apocalyptic beliefs and claims "justification by a Hadith that they interpret as portraying the revival of slavery as a precursor to the end of the world".

ISIL announced the revival of slavery as an institution. In 2015 the official slave prices set by ISIL were following:

Children aged 1 to 9 were sold for 200,000 dinars ($169).

Women and children 10 to 20 years old for 150,000 dinars ($127).

Women 20 to 30 years old for 100,000 dinar ($85).

Women 30 to 40 years old are 75,000 dinar ($63).

Women 40 to 50 years old for 50,000 dinar ($42).

However some slaves have been sold for as little as a pack of cigarettes. Sex slaves were sold to Saudi Arabia, other Persian Gulf states and Turkey.

Slavery has existed all throughout Asia, and forms of slavery still exist today.

Scholars differ as to whether or not slaves and the institution of slavery existed in ancient India. These English words have no direct, universally accepted equivalent in Sanskrit or other Indian languages, but some scholars translate the word , mentioned in texts like Manu Smriti, as slaves. Ancient historians who visited India offer the closest insights into the nature of Indian society and slavery in other ancient civilizations. For example, the Greek historian Arrian, who chronicled India about the time of Alexander the Great, wrote in his Indika,

The Indians do not even use aliens as slaves, much less a countryman of their own.

Qin dynasty (221-206 BC) Men sentenced to castration became eunuch slaves of the Qin dynasty state and as a result they were made to do forced labor, on projects like the Terracotta Army. The Qin government confiscated the property and enslaved the families of those who received castration as a punishment for rape.
Slaves were deprived of their rights and connections to their families.

Han dynasty (206 BC - 220 AD) One of Emperor Gao's first acts was to set free from slavery agricultural workers who were enslaved during the Warring States period, although domestic servants retained their status.

Men punished with castration during the Han dynasty were also used as slave labor.

Deriving from earlier Legalist laws, the Han dynasty set in place rules that the property of and families of criminals doing three years of hard labor or sentenced to castration were to have their families seized and kept as property by the government.

During the millennium long Chinese domination of Vietnam, Vietnam was a great source of slave girls who were used as sex slaves in China. The slave girls of Viet were even eroticized in Tang dynasty poetry.

The Islamic invasions, starting in the 8th century, also resulted in hundreds of thousands of Indians being enslaved by the invading armies, one of the earliest being the armies of the Umayyad commander Muhammad bin Qasim. Qutb-ud-din Aybak, a Turkic slave of Muhammad Ghori rose to power following his master's death. For almost a century, his descendants ruled North-Central India in form of Slave Dynasty. Several slaves were also brought to India by the Indian Ocean trades; for example, the Siddi are descendants of Bantu slaves brought to India by Arab and Portuguese merchants.

Andre Wink summarizes the slavery in 8th and 9th century India as follows,

(During the invasion of Muhammad al-Qasim), invariably numerous women and children were enslaved. The sources insist that now, in dutiful conformity to religious law, 'the one-fifth of the slaves and spoils' were set apart for the caliph's treasury and despatched to Iraq and Syria. The remainder was scattered among the army of Islam. At Rūr, a random 60,000 captives reduced to slavery. At Brahamanabad 30,000 slaves were allegedly taken. At Multan 6,000. Slave raids continued to be made throughout the late Umayyad period in Sindh, but also much further into Hind, as far as Ujjain and Malwa. The Abbasid governors raided Punjab, where many prisoners and slaves were taken.

In the early 11th century Tarikh al-Yamini, the Arab historian Al-Utbi recorded that in 1001 the armies of Mahmud of Ghazna conquered Peshawar and Waihand (capital of Gandhara) after Battle of Peshawar (1001), "in the midst of the land of Hindustan", and captured some 100,000 youths. Later, following his twelfth expedition into India in 1018-19, Mahmud is reported to have returned with such a large number of slaves that their value was reduced to only two to ten dirhams each. This unusually low price made, according to Al-Utbi, "merchants [come] from distant cities to purchase them, so that the countries of Central Asia, Iraq and Khurasan were swelled with them, and the fair and the dark, the rich and the poor, mingled in one common slavery". Elliot and Dowson refer to "five hundred thousand slaves, beautiful men and women.". Later, during the Delhi Sultanate period (1206-1555), references to the abundant availability of low-priced Indian slaves abound. Levi attributes this primarily to the vast human resources of India, compared to its neighbors to the north and west (India's Mughal population being approximately 12 to 20 times that of Turan and Iran at the end of the 16th century).

Slavery and empire-formation tied in particularly well with iqta and it is within this context of Islamic expansion that elite slavery was later commonly found. It became the predominant system in North India in the thirteenth century and retained considerable importance in the fourteenth century. Slavery was still vigorous in fifteenth-century Bengal, while after that date it shifted to the Deccan where it persisted until the seventeenth century. It remained present to a minor extent in the Mughal provinces throughout the seventeenth century and had a notable revival under the Afghans in North India again in the eighteenth century.

The Delhi sultanate obtained thousands of slaves and eunuch servants from the villages of Eastern Bengal (a widespread practice which Mughal emperor Jahangir later tried to stop). Wars, famines, pestilences drove many villagers to sell their children as slaves. The Muslim conquest of Gujarat in Western India had two main objectives. The conquerors demanded and more often forcibly wrested both land owned by Hindus and Hindu women. Enslavement of women invariably led to their conversion to Islam. In battles waged by Muslims against Hindus in Malwa and Deccan plateau, a large number of captives were taken. Muslim soldiers were permitted to retain and enslave POWs as plunder.

The first Bahmani sultan, Alauddin Bahman Shah is noted to have captured 1,000 singing and dancing girls from Hindu temples after he battled the northern Carnatic chieftains. The later Bahmanis also enslaved civilian women and children in wars; many of them were converted to Islam in captivity. About the Mughal empire, W.H. Moreland observed, "it became a fashion to raid a village or group of villages without any obvious justification, and carry off the inhabitants as slaves."

During the rule of Shah Jahan, many peasants were compelled to sell their women and children into slavery to meet the land revenue demand. Slavery was officially abolished in British India by the Indian Slavery Act, 1843. However, in modern India, Pakistan and Nepal, there are millions of bonded laborers, who work as slaves to pay off debts.

The Tang dynasty purchased Western slaves from the Radanite Jews. Tang Chinese soldiers and pirates enslaved Koreans, Turks, Persians, Indonesians, and people from Inner Mongolia, Central Asia, and northern India. The greatest source of slaves came from southern tribes, including Thais and aboriginals from the southern provinces of Fujian, Guangdong, Guangxi, and Guizhou. Malays, Khmers, Indians, and black Africans were also purchased as slaves in the Tang dynasty. Slavery was prevalent until the late 19th century and early 20th century China. All forms of slavery have been illegal in China since 1910.

Slavery in Japan was, for most of its history, indigenous, since the export and import of slaves was restricted by Japan being a group of islands. In late-16th-century Japan, slavery was officially banned; but forms of contract and indentured labor persisted alongside the period penal codes' forced labor. During the Second Sino-Japanese War and the Pacific War, the Japanese military used millions of civilians and prisoners of war from several countries as forced laborers.

In Korea, slavery was officially abolished with the Gabo Reform of 1894. During the Joseon period, in times of poor harvest and famine, many peasants voluntarily sold themselves into the nobi system in order to survive.

In Southeast Asia, there was a large slave class in Khmer Empire who built the enduring monuments in Angkor Wat and did most of the heavy work. Between the 17th and the early 20th centuries one-quarter to one-third of the population of some areas of Thailand and Burma were slaves. By the 19th century, Bhutan had developed a slave trade with Sikkim and Tibet, also enslaving British subjects and Brahmins. According to the International Labour Organization (ILO), during the early 21st century an estimated 800,000 people are subject to forced labor in Myanmar.

Slavery in pre-Spanish Philippines was practiced by the tribal Austronesian peoples who inhabited the culturally diverse islands. The neighbouring Muslim states conducted slave raids from the 1600s into the 1800s in coastal areas of the Gulf of Thailand and the Philippine islands. Slaves in Toraja society in Indonesia were family property. People would become slaves when they incurred a debt. Slaves could also be taken during wars, and slave trading was common. Torajan slaves were sold and shipped out to Java and Siam. Slaves could buy their freedom, but their children still inherited slave status. Slavery was abolished in 1863 in all Dutch colonies.

Records of slavery in Ancient Greece go as far back as Mycenaean Greece. The origins are not known, but it appears that slavery became an important part of the economy and society only after the establishment of cities. Slavery was common practice and an integral component of ancient Greece, as it was in other societies of the time, including ancient Israel. It is estimated that in Athens, the majority of citizens owned at least one slave. Most ancient writers considered slavery not only natural but necessary, but some isolated debate began to appear, notably in Socratic dialogues. The Stoics produced the first condemnation of slavery recorded in history.

During the 8th and the 7th centuries BC, in the course of the two Messenian Wars, the Spartans reduced an entire population to a pseudo-slavery called . According to Herodotus (IX, 28-29), helots were seven times as numerous as Spartans. Following several helot revolts around the year 600 BC, the Spartans restructured their city-state along authoritarian lines, for the leaders decided that only by turning their society into an armed camp could they hope to maintain control over the numerically dominant helot population. In some Ancient Greek city-states, about 30% of the population consisted of slaves, but paid and slave labor seem to have been equally important.

Romans inherited the institution of slavery from the Greeks and the Phoenicians. As the Roman Republic expanded outward, it enslaved entire populations, thus ensuring an ample supply of laborers to work in Rome's farms, quarries and households. The people subjected to Roman slavery came from all over Europe and the Mediterranean. Such oppression by an elite minority eventually led to slave revolts; the Third Servile War led by Spartacus was the most famous and severe. Greeks, Berbers, Germans, Britons, Slavs, Thracians, Gauls (or Celts), Jews, Arabs and many more ethnic groups were enslaved to be used for labor, and also for amusement (e.g. gladiators and sex slaves). If a slave ran away, they were liable to be crucified.

The overall impact of slavery on the Italian genetics was insignificant though, because the slaves imported in Italy were native Europeans, and very few if any of them had extra European origin. This has been further confirmed by recent biochemical analysis of 166 skeletons from three non-elite imperial-era cemeteries in the vicinity of Rome (where the bulk of the slaves lived), which shows that only 1 individual definitely came from outside of Europe (North Africa), and another 2 possibly did, but results are inconclusive. In the rest of the Italian peninsula, the amount of non European slaves was definitively much lower than that.

The chaos of invasion and frequent warfare also resulted in victorious parties taking slaves throughout Europe in the early Middle Ages. St. Patrick, himself captured and sold as a slave, protested against an attack that enslaved newly baptized Christians in his "Letter to the Soldiers of Coroticus". As a commonly traded commodity, like cattle, slaves could become a form of internal or trans-border currency. Slavery during the Early Middle Ages had several distinct sources.

The Vikings raided across Europe, but took the most slaves in raids on the British Isles and in Eastern Europe. While the Vikings kept some slaves as servants, known as , they sold most captives in the Byzantine or Islamic markets. In the West, their target populations were primarily English, Irish, and Scottish, while in the East they were mainly Slavs. The Viking slave-trade slowly ended in the 11th century, as the Vikings settled in the European territories they had once raided. They converted serfs to Christianity and themselves merged with the local populace.

In central Europe, specifically the Frankish/German/Holy Roman Empire of Charlemagne, raids and wars to the east generated a steady supply of slaves from the Slavic captives of these regions. Because of high demand for slaves in the wealthy Muslim empires of Northern Africa, Spain, and the Near East, especially for slaves of European descent, a market for these slaves rapidly emerged. So lucrative was this market that it spawned an economic boom in central and western Europe, today known as the Carolingian Renaissance. This boom period for slaves stretched from the early Muslim conquests to the High Middle Ages but declined in the later Middle Ages as the Islamic Golden Age waned.

Medieval Spain and Portugal saw almost constant warfare between Muslims and Christians. Al-Andalus sent periodic raiding expeditions to loot the Iberian Christian kingdoms, bringing back booty and slaves. In a raid against Lisbon, Portugal in 1189, for example, the Almohad caliph Yaqub al-Mansur took 3,000 female and child captives. In a subsequent attack upon Silves, Portugal in 1191, his governor of Córdoba took 3,000 Christian slaves.

The Byzantine-Ottoman wars and the Ottoman wars in Europe resulted in the taking of large numbers of Christian slaves and using or selling them in the Islamic world too. After the battle of Lepanto the victors freed approximately 12,000 Christian galley slaves from the Ottoman fleet.

Similarly, Christians sold Muslim slaves captured in war. The Order of the Knights of Malta attacked pirates and Muslim shipping, and their base became a centre for slave trading, selling captured North Africans and Turks. Malta remained a slave market until well into the late 18th century. One thousand slaves were required to man the galleys (ships) of the Order.

Poland banned slavery in the 15th century; in Lithuania, slavery was formally abolished in 1588; the institution was replaced by the second enserfment. Slavery remained a minor institution in Russia until 1723, when Peter the Great converted the household slaves into house serfs. Russian agricultural slaves were formally converted into serfs earlier, in 1679. The escaped Russian serfs and kholops formed autonomous communities in the southern steppes, where they became known as Cossacks (meaning "outlaws").

Capture in war, voluntary servitude and debt slavery became common within the British Isles before 1066. Slaves were routinely bought and sold. Running away was also common and slavery was never a major economic factor in the British Isles during the Middle Ages. Ireland and Denmark provided markets for captured Anglo-Saxon and Celtic slaves. Pope Gregory I reputedly made the pun, Non Angli, sed Angeli ("Not Angles, but Angels"), after a response to his query regarding the identity of a group of fair-haired Angles, slave children whom he had observed in the marketplace. After the Norman Conquest, the law no longer supported chattel slavery and slaves became part of the larger body of serfs.

Barbary pirates and Maltese corsairs both raided for slaves and purchased slaves from European merchants, often the Radhanites, one of the few groups who could easily move between the Christian and Islamic worlds.

In the late Middle Ages, from 1100 to 1500, the European slave-trade continued, though with a shift from being centered among the Western Mediterranean Islamic nations to the Eastern Christian and Muslim states. The city-states of Venice and Genoa controlled the Eastern Mediterranean from the 12th century and the Black Sea from the 13th century. They sold both Slavic and Baltic slaves, as well as Georgians, Turks, and other ethnic groups of the Black Sea and Caucasus. The sale of European slaves by Europeans slowly ended as the Slavic and Baltic ethnic groups Christianized by the Late Middle Ages. European slaves did not pass on an inherited status and was thus more akin to forced labor, or indentured servitude.

From the 1440s into the 18th century, Europeans from Italy, Spain, Portugal, France, and England were sold into slavery by North Africans, as described in the book "Christian Slaves, Muslim Masters". This same book states that "white slavery had been minimised or ignored because academics preferred to treat Europeans as evil colonialists rather than as victims." and likely overestimates the number of slaves taken. In 1575, the Tatars captured over 35,000 Ukrainians; a 1676 raid took almost 40,000. About 60,000 Ukrainians were captured in 1688; some were ransomed, but most were sold into slavery. Some of the Roma people were enslaved over five centuries in Romania until abolition in 1864 (see Slavery in Romania).

The Mongol invasions and conquests in the 13th century also resulted in taking numerous captives into slavery. The Mongols enslaved skilled individuals, women and children and marched them to Karakorum or Sarai, whence they were sold throughout Eurasia. Many of these slaves were shipped to the slave market in Novgorod.

Slave commerce during the Late Middle Ages was mainly in the hands of Venetian and Genoese merchants and cartels, who were involved in the slave trade with the Golden Horde. In 1382 the Golden Horde under Khan Tokhtamysh sacked Moscow, burning the city and carrying off thousands of inhabitants as slaves. Between 1414 and 1423, some 10,000 eastern European slaves were sold in Venice. Genoese merchants organized the slave trade from the Crimea to Mamluk Egypt. For years, the Khanates of Kazan and Astrakhan routinely made raids on Russian principalities for slaves and to plunder towns. Russian chronicles record about 40 raids by Kazan Khans on the Russian territories in the first half of the 16th century.

In 1441 Haci I Giray declared independence from the Golden Horde and established the Crimean Khanate. For a long time, until the early 18th century, the khanate maintained an extensive slave-trade with the Ottoman Empire and the Middle East. In a process called the "harvesting of the steppe" they enslaved many Slavic peasants. About 30 major Tatar raids were recorded into Muscovite territories between 1558 and 1596.

Moscow was repeatedly a target. In 1521, the combined forces of Crimean Khan Mehmed Giray and his Kazan allies attacked the city and captured thousands of slaves. In 1571, the Crimean Tatars attacked and sacked Moscow, burning everything but the Kremlin and taking thousands of captives as slaves. In Crimea, about 75% of the population consisted of slaves.

In the Viking era beginning circa 793, the Norse raiders often captured and enslaved militarily weaker peoples they encountered. The Nordic countries called their slaves ( Old Norse: Þræll). The thralls were mostly from Western Europe, among them many Franks, Frisians, Anglo-Saxons, and both Irish and Britonnic Celts. Many Irish slaves travelled in expeditions for the colonization of Iceland. The Norse also took German, Baltic, Slavic and Latin slaves. The slave trade was one of the pillars of Norse commerce during the 6th through 11th centuries. The 10th-century Persian traveller Ibn Rustah described how Swedish Vikings, the Varangians or Rus, terrorized and enslaved the Slavs taken in their raids along the Volga River. The thrall system was finally abolished in the mid-14th century in Scandinavia.

Mediterranean powers frequently sentenced convicted criminals to row in the war- galleys of the state (initially only in time of war). After the revocation of the Edict of Nantes in 1685 and Camisard rebellion, the French Crown filled its galleys with French Huguenots, Protestants condemned for resisting the state. Galley-slaves lived and worked in such harsh conditions that many did not survive their terms of sentence, even if they survived shipwreck and slaughter or torture at the hands of enemies or of pirates. Naval forces often turned 'infidel' prisoners-of-war into galley-slaves. Several well-known historical figures served time as galley slaves after being captured by the enemy-the Ottoman corsair and admiral Turgut Reis and the Knights Hospitaller Grand Master Jean Parisot de la Valette among them.

Denmark-Norway was the first European country to ban the slave trade. This happened with a decree issued by King Christian VII of Denmark in 1792, to become fully effective by 1803. Slavery as an institution was not banned until 1848. At this time Iceland was a part of Denmark-Norway but slave trading had been abolished in Iceland in 1117 and had never been reestablished.

Slavery in the French Republic was abolished on 4 February 1794, including in its colonies. The lengthy Haitian Revolution by its slaves and free people of color established Haiti as a free republic in 1804 ruled by blacks, the first of its kind. At the time of the revolution, Haiti was known as Saint-Domingue and was a colony of France. Napoleon Bonaparte gave up on Haiti in 1803, but re-established slavery in Guadeloupe and Martinique in 1804, at the request of planters of the Caribbean colonies. Slavery was permanently abolished in the French empire during the French Revolution of 1848.

The 15th-century Portuguese exploration of the African coast is commonly regarded as the harbinger of European colonialism. In 1452, Pope Nicholas V issued the papal bull Dum Diversas, granting Afonso V of Portugal the right to reduce any "Saracens, pagans and any other unbelievers" to hereditary slavery which legitimized slave trade under Catholic beliefs of that time. This approval of slavery was reaffirmed and extended in his Romanus Pontifex bull of 1455. These papal bulls came to serve as a justification for the subsequent era of the slave trade and European colonialism. Although for a short period as in 1462, Pius II declared slavery to be "a great crime". The followers of the church of England and Protestants did not use the papal bull as a justification. The position of the church was to condemn the slavery of Christians, but slavery was regarded as an old established and necessary institution which supplied Europe with the necessary workforce. In the 16th century, African slaves had replaced almost all other ethnicities and religious enslaved groups in Europe. Within the Portuguese territory of Brazil, and even beyond its original borders, the enslavement of Native Americans was carried out by the Bandeirantes.

Among many other European slave markets, Genoa, and Venice were some well-known markets, their importance and demand growing after the great plague of the 14th century which decimated much of the European workforce. The maritime town of Lagos, Portugal, was the first slave market created in Portugal for the sale of imported African slaves, the Mercado de Escravos, which opened in 1444. In 1441, the first slaves were brought to Portugal from northern Mauritania. Prince Henry the Navigator, major sponsor of the Portuguese African expeditions, as of any other merchandise, taxed one fifth of the selling price of the slaves imported to Portugal. By the year 1552 African slaves made up 10 percent of the population of Lisbon. In the second half of the 16th century, the Crown gave up the monopoly on slave trade and the focus of European trade in African slaves shifted from import to Europe to slave transports directly to tropical colonies in the Americas-in the case of Portugal, especially Brazil. In the 15th century, one-third of the slaves were resold to the African market in exchange of gold. Slavery was abolished in mainland Portugal and Portuguese India in 1761. It was finally abolished in all Portuguese colonies in 1869.

The Spaniards were the first Europeans to use African slaves in the New World on islands such as Cuba and Hispaniola, due to a shortage of labor caused by the spread of diseases, and so the Spanish colonists gradually became involved in the Atlantic slave trade. The first African slaves arrived in Hispaniola in 1501; by 1517, the natives had been "virtually annihilated" mostly to diseases. The problem of the justness of Native American's slavery was a key issue for the Spanish Crown. It was Charles V who gave a definite answer to this complicated and delicate matter. To that end, on 25 November 1542, the Emperor abolished slavery by decree in his Leyes Nuevas New Laws. This bill was based on the arguments given by the best Spanish theologists and jurists who were unanimous in the condemnation of such slavery as unjust; they declared it illegitimate and outlawed it from America-not just the slavery of Spaniards over Natives-but also the type of slavery practiced among the Natives themselves Thus, Spain became the first country to officially abolish slavery.

However, in the Spanish colonies of Cuba and Puerto Rico, where sugarcane production was highly profitable based on slave labor, African slavery persisted until 1873 in Puerto Rico "with provisions for periods of apprenticeship", and 1886 in Cuba.

Although slavery was illegal inside the Netherlands it flourished throughout the Dutch Empire in the Americas, Africa, Ceylon and Indonesia. The Dutch Slave Coast ( Dutch: Slavenkust) referred to the trading posts of the Dutch West India Company on the Slave Coast, which lie in contemporary Ghana, Benin, Togo and Nigeria. Initially the Dutch shipped slaves to northern Brazil, and during the second half of the 17th century they had a controlling interest in the trade to the Spanish colonies. Today's Suriname and Guyana became prominent markets in the 18th century. Between 1612 and 1872, the Dutch operated from some 10 fortresses along the Gold Coast (now Ghana), from which slaves were shipped across the Atlantic. Dutch involvement on the Slave Coast increased with the establishment of a trading post in Offra in 1660. Willem Bosman writes in his Nauwkeurige beschrijving van de Guinese Goud- Tand- en Slavekust (1703) that Allada was also called Grand Ardra, being the larger cousin of Little Ardra, also known as Offra. From 1660 onward, Dutch presence in Allada and especially Offra became more permanent. A report from this year asserts Dutch trading posts, apart from Allada and Offra, in Benin City, Grand-Popo, and Savi.

The Offra trading post soon became the most important Dutch office on the Slave Coast. According to a 1670 report, annually 2,500 to 3,000 slaves were transported from Offra to the Americas. These numbers were only feasible in times of peace, however, and dwindled in time of conflict. From 1688 onward, the struggle between the Aja king of Allada and the peoples on the coastal regions, impeded the supply of slaves. The Dutch West India Company chose the side of the Aja king, causing the Offra office to be destroyed by opposing forces in 1692. By 1650 the Dutch had the pre-eminent slave trade in Europe and South East Asia. Later, trade shifted to Ouidah. On the instigation of Governor-General of the Dutch Gold Coast Willem de la Palma, Jacob van den Broucke was sent in 1703 as "opperkommies" (head merchant) to the Dutch trading post at Ouidah, which according to sources was established around 1670. Political unrest caused the Dutch to abandon their trading post at Ouidah in 1725, and they then moved to Jaquim, at which place they built Fort Zeelandia. The head of the post, Hendrik Hertog, had a reputation for being a successful slave trader. In an attempt to extend his trading area, Hertog negotiated with local tribes and mingled in local political struggles. He sided with the wrong party, however, leading to a conflict with Director-General Jan Pranger and to his exile to the island of Appa in 1732. The Dutch trading post on this island was extended as the new centre of the slave trade. In 1733, Hertog returned to Jaquim, this time extending the trading post into Fort Zeelandia. The revival of the slave trade at Jaquim was only temporary, however, as his superiors at the Dutch West India Company noticed that Hertog's slaves were more expensive than at the Gold Coast. From 1735, Elmina became the preferred spot to trade slaves. As of 1778, it was estimated that the Dutch were shipping approximately 6,000 Africans for enslavement in the Dutch West Indies each year. Slavery also characterised the Dutch possessions in Indonesia, Ceylon and South Africa, where Indonesians have made a significant contribution to the Cape Coloured population of that country. The Dutch part in the Atlantic slave trade is estimated at 5-7 percent, as they shipped about 550,000-600,000 African slaves across the Atlantic, about 75,000 of whom died on board before reaching their destinations. From 1596 to 1829, the Dutch traders sold 250,000 slaves in the Dutch Guianas, 142,000 in the Dutch Caribbean islands, and 28,000 in Dutch Brazil. In addition, tens of thousands of slaves, mostly from India and some from Africa, were carried to the Dutch East Indies. The Netherlands was one of the last countries to abolish slavery in 1863. Although the decision was made in 1848, it took many years for the law to be implemented. Furthermore, slaves in Suriname would be fully free only in 1873, since the law stipulated that there was to be a mandatory 10-year transition.

Barbary Corsairs continued to trade in European slaves into the Modern time-period. Muslim pirates, primarily Algerians with the support of the Ottoman Empire, raided European coasts and shipping from the 16th to the 19th centuries, and took thousands of captives, whom they sold or enslaved. Many were held for ransom, and European communities raised funds such as Malta's Monte della Redenzione degli Schiavi to buy back their citizens. The raids gradually ended with the naval decline of the Ottoman Empire in the late 16th and 17th centuries, as well as the European conquest of North Africa throughout the 19th century.

From 1609 to 1616, England lost 466 merchant ships to Barbary pirates. 160 English ships were captured by Algerians between 1677 and 1680. Many of the captured sailors were made into slaves and held for ransom. The corsairs were no strangers to the South West of England where raids were known in a number of coastal communities. In 1627 Barbary Pirates under command of the Dutch renegade Jan Janszoon (Murat Reis), operating from the Moroccan port of Salé, occupied the island of Lundy. During this time there were reports of captured slaves being sent to Algiers.

Ireland, despite its northern position, was not immune from attacks by the corsairs. In June 1631 Janszoon, with pirates from Algiers and armed troops of the Ottoman Empire, stormed ashore at the little harbor village of Baltimore, County Cork. They captured almost all the villagers and took them away to a life of slavery in North Africa. The prisoners were destined for a variety of fates-some lived out their days chained to the oars as galley slaves, while others would spend long years in the scented seclusion of the harem or within the walls of the sultan's palace. Only two of them ever saw Ireland again.

The Congress of Vienna (1814-15), which ended the Napoleonic Wars, led to increased European consensus on the need to end Barbary raiding. The sacking of Palma on the island of Sardinia by a Tunisian squadron, which carried off 158 inhabitants, roused widespread indignation. Britain had by this time banned the slave trade and was seeking to induce other countries to do likewise. States that were more vulnerable to the corsairs complained that Britain cared more for ending the trade in African slaves than stopping the enslavement of Europeans and Americans by the Barbary States.

In order to neutralise this objection and further the anti-slavery campaign, in 1816 Britain sent Lord Exmouth to secure new concessions from Tripoli, Tunis, and Algiers, including a pledge to treat Christian captives in any future conflict as prisoners of war rather than slaves. He imposed peace between Algiers and the kingdoms of Sardinia and Sicily. On his first visit, Lord Exmouth negotiated satisfactory treaties and sailed for home. While he was negotiating, a number of Sardinian fishermen who had settled at Bona on the Tunisian coast were brutally treated without his knowledge. As Sardinians they were technically under British protection, and the government sent Exmouth back to secure reparation. On 17 August, in combination with a Dutch squadron under Admiral Van de Capellen, Exmouth bombarded Algiers. Both Algiers and Tunis made fresh concessions as a result.

The Barbary states had difficulty securing uniform compliance with a total prohibition of slave-raiding, as this had been traditionally of central importance to the North African economy. Slavers continued to take captives by preying on less well-protected peoples. Algiers subsequently renewed its slave-raiding, though on a smaller scale. Europeans at the Congress of Aix-la-Chapelle in 1818 discussed possible retaliation. In 1820 a British fleet under Admiral Sir Harry Neal bombarded Algiers. Corsair activity based in Algiers did not entirely cease until France conquered the state in 1830.

The Crimeans frequently mounted raids into the Danubian principalities, Poland-Lithuania, and Muscovy to enslave people whom they could capture; for each captive, the khan received a fixed share (savğa) of 10% or 20%. These campaigns by Crimean forces were either sefers ("sojourns" - officially declared military operations led by the khans themselves), or çapuls ("despoiling" - raids undertaken by groups of noblemen, sometimes illegally because they contravened treaties concluded by the khans with neighbouring rulers).

For a long time, until the early 18th century, the Crimean Khanate maintained a massive slave trade with the Ottoman Empire and the Middle East, exporting about 2 million slaves from Russia and Poland-Lithuania over the period 1500-1700. Caffa (modern Feodosia) became one of the best-known and significant trading ports and slave markets. In 1769 the last major Tatar raid saw the capture of 20,000 Russian and Ruthenian slaves.

Author and historian Brian Glyn Williams writes:

Fisher estimates that in the sixteenth century the Polish-Lithuanian Commonwealth lost around 20,000 individuals a year and that from 1474 to 1694, as many as a million Commonwealth citizens were carried off into Crimean slavery.

Early modern sources are full of descriptions of sufferings of Christian slaves captured by the Crimean Tatars in the course of their raids:

It seems that the position and everyday conditions of a slave depended largely on his/her owner. Some slaves indeed could spend the rest of their days doing exhausting labor: as the Crimean vizir (minister) Sefer Gazi Aga mentions in one of his letters, the slaves were often "a plough and a scythe" of their owners. Most terrible, perhaps, was the fate of those who became galley-slaves, whose sufferings were poeticized in many Ukrainian dumas (songs). ... Both female and male slaves were often used for sexual purposes.

Britain played a prominent role in the Atlantic slave trade, especially after 1640, when sugar cane was introduced to the region. At first, most were white Britons, or Irish, enslaved as indentured labour - for a fixed period - in the West Indies. These people may have been criminals, political rebels, the poor with no prospects or others who were simply tricked or kidnapped. Slavery was a legal institution in all of the 13 American colonies and Canada (acquired by Britain in 1763). The profits of the slave trade and of West Indian plantations amounted to 5% of the British economy at the time of the Industrial Revolution.

A little-known incident in the career of Judge Jeffreys refers to an assize in Bristol in 1685 when he made the mayor of the city, then sitting fully robed beside him on the bench, go into the dock and be fined £1000 for being a 'kidnapping knave'; some Bristol traders at the time were known at the time to kidnap their own countrymen and ship them away as slaves.

Somersett's case in 1772 was generally taken at the time to have decided that the condition of slavery did not exist under English law in England. In 1785, English poet William Cowper wrote: "We have no slaves at home - Then why abroad? Slaves cannot breathe in England; if their lungs receive our air, that moment they are free. They touch our country, and their shackles fall. That's noble, and bespeaks a nation proud. And jealous of the blessing. Spread it then, And let it circulate through every vein." However, slavery continued to thrive in England itself, much like it did in the British Empire, until full emancipation in the 1830s. In 1807, following many years of lobbying by the abolitionist movement, led primarily by William Wilberforce, the British Parliament voted to make the slave trade illegal anywhere in the Empire with the Slave Trade Act 1807. Thereafter Britain took a prominent role in combating the trade, and slavery itself was abolished in the British Empire (except for India) with the Slavery Abolition Act 1833. Between 1808 and 1860, the West Africa Squadron seized approximately 1,600 slave ships and freed 150,000 Africans who were aboard. Action was also taken against African leaders who refused to agree to British treaties to outlaw the trade. Akitoye, the 11th Oba of Lagos, is famous for having used British involvement to regain his rule in return for suppressing slavery among the Yoruba people of Lagos in 1851. Anti-slavery treaties were signed with over 50 African rulers. In 1839, the world's oldest international human rights organization, Anti-Slavery International, was formed in Britain by Joseph Sturge, which worked to outlaw slavery in other countries.

After 1833, the freed African slaves declined employment in the cane fields. This led to the importation of indentured labour again - mainly from India, and also China.

In 1811, Arthur William Hodge was executed for the murder of a slave in the British West Indies. He was not, however, as some have claimed, the first white person to have been lawfully executed for the murder of a slave.

During World War II Nazi Germany operated several categories of Arbeitslager (Labor Camps) for different categories of inmates. The largest number of them held Polish and Jewish civilians forcibly abducted in the occupied countries (see Łapanka) to provide labor in the German war industry, repair bombed railroads and bridges or work on farms. By 1944, 20% of all workers were foreigners, either civilians or prisoners of war.

This is not classed as slavery per se, as defined in the first paragraph, i.e. slavery under this definition does not include other forced labour systems, such as historical forced labor by prisoners, labor camps, or other forms of unfree labor, in which labourers are not legally considered property. Slavery typically requires a shortage of labor and a surplus of land to be viable.

As agreed by the Allies at the Yalta conference Germans were used as forced labor as part of the reparations to be extracted. By 1947 it is estimated that 400,000 Germans (both civilians and POWs) were being used as forced labor by the U.S., France, the UK and the Soviet Union. German prisoners were for example forced to clear minefields in France and the Low Countries. By December 1945 it was estimated by French authorities that 2,000 German prisoners were being killed or injured each month in accidents. In Norway the last available casualty record, from 29 August 1945, shows that by that time a total of 275 German soldiers died while clearing mines, while 392 had been injured. Death rates for the German civilians doing forced labor in the Soviet Union ranged between 19% and 39%, depending on category.

In the first half of the 19th century, small-scale slave raids took place across Polynesia to supply labor and sex workers for the whaling and sealing trades, with examples from both the westerly and easterly extremes of the Polynesian triangle. By the 1860s this had grown to a larger scale operation with Peruvian slave raids in the South Sea Islands to collect labor for the guano industry.

Ancient Hawaii was a caste society. People were born into specific social classes. Kauwa were those of the outcast or slave class. They are believed to have been war captives, or the descendants of war captives. Marriage between higher castes and the kauwa was strictly forbidden. The kauwa worked for the chiefs and were often used as human sacrifices at the luakini heiau. (They were not the only sacrifices; law-breakers of all castes or defeated political opponents were also acceptable as victims.)

The kapu system was abolished during the ʻAi Noa in 1819, and with it the distinction between the kauwā slave class and the makaʻāinana (commoners). The 1852 Constitution of the Kingdom of Hawaii officially made slavery illegal.

Before the arrival of European settlers, each Maori tribe () considered itself a separate entity equivalent to a nation. In traditional Maori society of Aotearoa, prisoners of war became taurekareka, slaves, unless released, ransomed or eaten. With some exceptions, the child of a slave remained a slave.

As far as it is possible to tell, slavery seems to have increased in the early 19th century with increased numbers of prisoners being taken by Māori military leaders, such as Hongi Hika and Te Rauparaha to satisfy the need for labor in the Musket Wars, to supply whalers and traders with food, flax and timber in return for western goods. The intertribal Musket Wars lasted 1807 to 1843 when large numbers of slaves were captured by northern tribes who had acquired muskets. About 20,000 Maori died in the wars which were concentrated in the North Island. An unknown number of slaves were captured. Northern tribes used slaves (called mokai) to grow large areas of potatoes for trade with visiting ships. Chiefs started an extensive sex trade in the Bay of Islands in the 1830s using mainly slave girls. By 1835 about 70-80 ships per year called into the port. One French captain described the impossibility of getting rid of the girls who swarmed over his ship outnumbering his crew of 70 by 3 to 1. All payments to the girls were stolen by the chief. By 1833 Christianity had become established in the north and large numbers of slaves were freed. However two Taranaki tribes, Ngati Tama and Ngati Mutunga, displaced by the wars carried out a carefully planned invasion of the Chatham Islands, 800 km east of Christchurch, in 1835. About 15% of the Polynesian Moriori natives who had migrated to the islands at about 1500 CE were killed, with many women being tortured to death. The remaining population was enslaved for the purpose of growing food, especially potatoes. The Moriori were treated in an inhumane and degrading manner for many years. Their culture was banned and they were forbidden to marry. Slavery was outlawed when the British entered into a constitutional arrangement with New Zealand in 1840 via the Treaty of Waitangi, although it did not end completely until government was effectively extended over the whole of the country with the defeat of the Kingi movement in the Wars of the mid-1860s.

Some Maori took Moriori partners. The state of enslavement of Moriori lasted until the 1860s although it had been discouraged by CMS missionaries in North New Zealand from the late 1820s. In 1870 Ngati Mutunga, one of the invading tribes, argued before the Native Land Court in New Zealand that their gross mistreatment of the Moriori was standard Maori practice or tikanga.

One group of Polynesians who migrated to the Chatham Islands became the Moriori who developed a largely pacifist culture. It was originally speculated that they settled the Chathams direct from Polynesia, but it is now widely believed they were disaffected Maori who emigrated from the South Island of New Zealand. Their pacifism left the Moriori unable to defend themselves when the islands were invaded by mainland Māori in the 1830s. Two Taranaki tribes, Ngati Tama and Ngati Mutunga, displaced by the musket wars, carried out a carefully planned invasion of the Chatham Islands, 800 km east of Christchurch, in 1835. About 15% of the Polynesian Moriori natives who had migrated to the islands at about 1500 CE were killed, with many women being tortured to death. The remaining population was enslaved for the purpose of growing food, especially potatoes. The Moriori were treated in an inhumane and degrading manner for many years. Their culture was banned and they were forbidden to marry. Slavery was outlawed when the British annexed New Zealand in 1840, immediately prior to the signing of the Treaty of Waitangi, although it did not end completely until government was effectively extended over the whole of the country with the defeat of the Kingi movement in the Wars of the mid-1860s.

Some 300 Moriori men, women and children were massacred and the remaining 1,200 to 1,300 survivors were enslaved.

Rapa Nui / Easter Island

The isolated island of Rapa Nui/ Easter Island was inhabited by the Rapanui, who suffered a series of slave raids from 1805 or earlier, culminating in a near genocidal experience in the 1860s. The 1805 raid was by American sealers and was one of a series that changed the attitude of the islanders to outside visitors, with reports in the 1820s and 1830s that all visitors received a hostile reception. In December 1862, Peruvian slave raiders took between 1,400 and 2,000 islanders back to Peru to work in the guano industry; this was about a third of the island's population and included much of the island's leadership, the last ariki-mau and possibly the last who could read Rongorongo. After intervention by the French ambassador in Lima, the last 15 survivors were returned to the island, but brought with them smallpox, which further devastated the island.

Slavery has existed, in one form or another, throughout the whole of human history. So, too, have movements to free large or distinct groups of slaves. However, abolitionism should be distinguished from efforts to help a particular group of slaves, or to restrict one practice, such as the slave trade.

Although there were numerous slave revolts in the Caribbean, the only successful uprising came in the French colony of Haiti in the 1790s, where the slaves rose up, killed the mulattoes and whites, and established the independent Republic of Haiti. Europe recoiled in horror.

Cyrus the Great, the founder of Persian Empire prohibited the systematic enslavement of conquered non-combatant population. Cyrus also freed slaves and allowed all deported peoples who were enslaved by preceding Assyrian and Babylonian kings, to return home. It is said that he freed up to 40,000 Jews and allowed them to return home. Cylinder of Cyrus the Great containing the Decree on the conquered non-combatant population.

In 1772, the Somersett Case (R. v. Knowles, ex parte Somersett) of the English Court of King's Bench ruled that it was unlawful for a slave to be forcibly taken abroad. The case has since been misrepresented as finding that slavery was unlawful in England (although not elsewhere in the British Empire). A similar case, that of Joseph Knight, took place in Scotland five years later and ruled slavery to be contrary to the law of Scotland.

Following the work of campaigners in the United Kingdom, such as William Wilberforce and Thomas Clarkson, the Act for the Abolition of the Slave Trade was passed by Parliament on 25 March 1807, coming into effect the following year. The act imposed a fine of £100 for every slave found aboard a British ship. The intention was to outlaw entirely the Atlantic slave trade within the whole British Empire.

The significance of the abolition of the British slave trade lay in the number of people hitherto sold and carried by British slave vessels. Britain shipped 2,532,300 Africans across the Atlantic, equalling 41% of the total transport of 6,132,900 individuals. This made the British empire the biggest slave-trade contributor in the world due to the magnitude of the empire, which made the abolition act all the more damaging to the global trade of slaves. Britain used its diplomatic influence to press other nations into treaties to ban their slave trade and to give the Royal Navy the right to interdict slave ships sailing under their national flag.

The Slavery Abolition Act, passed on 1 August 1833, outlawed slavery itself throughout the British Empire, with the exception of India. On 1 August 1834 slaves became indentured to their former owners in an apprenticeship system for six years. Full emancipation was granted ahead of schedule on 1 August 1838. Britain abolished slavery in both Hindu and Muslim India with the Indian Slavery Act, 1843.

Domestic slavery practised by the educated African coastal elites (as well as interior traditional rulers) in Sierra Leone was abolished in 1928. A study found practices of domestic slavery still widespread in rural areas in the 1970s.

There were slaves in mainland France (especially in trade ports such as Nantes or Bordeaux)., but the institution was never officially authorized there. The legal case of Jean Boucaux in 1739 clarified the unclear legal position of possible slaves in France, and was followed by laws that established registers for slaves in mainland France, who were limited to a three-year stay, for visits or learning a trade. Unregistered "slaves" in France were regarded as free. However, slavery was of vital importance in France's Caribbean possessions, especially Saint-Domingue.

In 1793, influenced by the French Declaration of the Rights of Man of August 1789 and alarmed as the massive slave revolt of August 1791 that had become the Haitian Revolution threatened to ally itself with the British, the French Revolutionary commissioners Sonthonax and Polverel declared general emancipation to reconcile them with France. In Paris, on 4 February 1794, Abbé Grégoire and the Convention ratified this action by officially abolishing slavery in all French territories outside mainland France, freeing all the slaves both for moral and security reasons.

Napoleon came to power in 1799 and soon had grandiose plans for the French sugar colonies; to achieve them he reintroduced slavery. Napoleon's major adventure into the Caribbean-sending 30,000 troops in 1802 to retake Saint Domingue (Haiti) from ex-slaves under Toussaint L'Ouverture who had revolted. Napoleon wanted to preserve France's financial benefits from the colony's sugar and coffee crops; he then planned to establish a major base at New Orleans. He therefore re-established slavery in Haiti and Guadeloupe, where it had been abolished after rebellions. Slaves and black freedmen fought the French for their freedom and independence. Revolutionary ideals played a central role in the fighting for it was the slaves and their allies who were fighting for the revolutionary ideals of freedom and equality, while the French troops under General Charles Leclerc fought to restore the order of the ancien régime. The goal of re-establishing slavery explicitly contradicted the ideals of the French Revolution. The French soldiers were unable to cope with the tropical diseases, and most died of yellow fever. Slavery was reimposed in Guadeloupe but not in Haiti, which became an independent black republic. Napoleon's vast colonial dreams for Egypt, India, the Caribbean, Louisiana, and even Australia were all doomed for lack of a fleet capable of matching Britain's Royal Navy. Realizing the fiasco Napoleon liquidated the Haiti project, brought home the survivors and sold off the huge Louisiana territory to the US in 1803.

In 1794 slavery was abolished in the French Empire. After seizing Lower Egypt in 1798, Napoleon Bonaparte issued a proclamation in Arabic, declaring all men to be free and equal. However, the French bought males as soldiers and females as concubines. Napoleon personally opposed the abolition and restored colonial slavery in 1802, a year after the capitulation of his troops in Egypt.

Victor Schœlcher and the 1848 abolition

The American Colonization Society, the primary vehicle for returning black Americans to greater freedom in Africa, established the colony of Liberia in 1821-23, on the premise that former American slaves would have greater freedom and equality there. The ACS assisted in the movement of thousands of African Americans to Liberia, with its founder Henry Clay stating; "unconquerable prejudice resulting from their color, they never could amalgamate with the free whites of this country. It was desirable, therefore, as it respected them, and the residue of the population of the country, to drain them off". Abraham Lincoln, an enthusiastic supporter of Clay, adopted his position on returning the blacks to their own land.

Slaves in the United States who escaped ownership would often make their way to Canada via the " Underground Railroad". The more famous of the African American abolitionists include former slaves Harriet Tubman, Sojourner Truth and Frederick Douglass. Many more people who opposed slavery and worked for abolition were northern whites, such as William Lloyd Garrison and John Brown. Slavery was legally abolished in 1865 by the Thirteenth Amendment to the United States Constitution.

While abolitionists agreed on the evils of slavery, there were differing opinions on what should happen after African Americans were freed. By the time of Emancipation, African-Americans were now native to the United States and did not want to leave. Most believed that their labor had made the land theirs as well as that of the whites.

The Declaration of the Powers, on the Abolition of the Slave Trade, of 8 February 1815 (Which also formed ACT, No. XV. of the Final Act of the Congress of Vienna of the same year) included in its first sentence the concept of the "principles of humanity and universal morality" as justification for ending a trade that was "odious in its continuance".

The 1926 Slavery Convention, an initiative of the League of Nations, was a turning point in banning global slavery. Article 4 of the Universal Declaration of Human Rights, adopted in 1948 by the UN General Assembly, explicitly banned slavery. The United Nations 1956 Supplementary Convention on the Abolition of Slavery was convened to outlaw and ban slavery worldwide, including child slavery. In December 1966, the UN General Assembly adopted the International Covenant on Civil and Political Rights, which was developed from the Universal Declaration of Human Rights. Article 4 of this international treaty bans slavery. The treaty came into force in March 1976 after it had been ratified by 35 nations.

As of November 2003, 104 nations had ratified the treaty. However, illegal forced labour involves millions of people in the 21st century, 43% for sexual exploitation and 32% for economic exploitation.

In May 2004, the 22 members of the Arab League adopted the Arab Charter on Human Rights, which incorporated the 1990 Cairo Declaration on Human Rights in Islam, which states:

Human beings are born free, and no one has the right to enslave, humiliate, oppress or exploit them, and there can be no subjugation but to God the Most-High.

-  Article 11, Cairo Declaration on Human Rights in Islam, 1990

Currently, the Anti-trafficking Coordination Team Initiative (ACT Team Initiative), a coordinated effort between the U.S. departments of justice, homeland security and labor, addresses human trafficking. The International Labour Organization estimates that there are 20.9 million victims of human trafficking globally, including 5.5 million children, of which 55% are women and girls.

The history of slavery originally was the history of the government's laws and policies toward slavery, and the political debates about it. Black history was promoted very largely at black colleges. The situation changed dramatically with the coming of the Civil Rights Movement of the 1950s. Attention shifted to the enslaved humans, the free blacks, and the struggles of the black community against adversity.

Peter Kolchin described the state of historiography in the early 20th century as follows:

During the first half of the twentieth century, a major component of this approach was often simply racism, manifest in the belief that blacks were, at best, imitative of whites. Thus Ulrich B. Phillips, the era's most celebrated and influential expert on slavery, combined a sophisticated portrait of the white planters' life and behavior with crude passing generalizations about the life and behavior of their black slaves.

Historians James Oliver Horton and Lois E. Horton described Phillips' mindset, methodology and influence:

His portrayal of blacks as passive, inferior people, whose African origins made them uncivilized, seemed to provide historical evidence for the theories of racial inferiority that supported racial segregation. Drawing evidence exclusively from plantation records, letters, southern newspapers, and other sources reflecting the slaveholder's point of view, Phillips depicted slave masters who provided for the welfare of their slaves and contended that true affection existed between master and slave.

Their account of the era rested, as one member of the Dunning school put it, on the assumption of "negro incapacity." Finding it impossible to believe that blacks could ever be independent actors on the stage of history, with their own aspirations and motivations, Dunning et al. portrayed African Americans either as "children", ignorant dupes manipulated by unscrupulous whites, or as savages, their primal passions unleashed by the end of slavery.

In the portrayal of the slave as a victim, the historian Stanley M. Elkins in his 1959 work Slavery: A Problem in American Institutional and Intellectual Life compared the effects of United States slavery to that resulting from the brutality of the Nazi concentration camps. He stated the institution destroyed the will of the slave, creating an "emasculated, docile Sambo" who identified totally with the owner. Elkins' thesis was challenged by historians. Gradually historians recognized that in addition to the effects of the owner-slave relationship, slaves did not live in a "totally closed environment but rather in one that permitted the emergence of enormous variety and allowed slaves to pursue important relationships with persons other than their master, including those to be found in their families, churches and communities."

Economic historians Robert W. Fogel and Stanley L. Engerman in the 1970s, through their work Time on the Cross, portrayed slaves as having internalized the Protestant work ethic of their owners. In portraying the more benign version of slavery, they also argue in their 1974 book that the material conditions under which the slaves lived and worked compared favorably to those of free workers in the agriculture and industry of the time. (This was also an argument of Southerners during the 19th century.)

In the 1970s and 1980s, historians made use of sources such as black music and statistical census data to create a more detailed and nuanced picture of slave life. Relying also on 19th-century autobiographies of ex-slaves (known as slave narratives) and the WPA Slave Narrative Collection, a set of interviews conducted with former slaves in the 1930s by the Federal Writers' Project, historians described slavery as the slaves remembered it. Far from slaves' being strictly victims or content, historians showed slaves as both resilient and autonomous in many of their activities. Despite their exercise of autonomy and their efforts to make a life within slavery, current historians recognize the precariousness of the slave's situation. Slave children quickly learned that they were subject to the direction of both their parents and their owners. They saw their parents disciplined just as they came to realize that they also could be physically or verbally abused by their owners. Historians writing during this era include John Blassingame ( Slave Community), Eugene Genovese ( Roll, Jordan, Roll), Leslie Howard Owens ( This Species of Property), and Herbert Gutman ( The Black Family in Slavery and Freedom).

Important work on slavery has continued; for instance, in 2003 Steven Hahn published the Pulitzer Prize-winning account, A Nation under Our Feet: Black Political Struggles in the Rural South from Slavery to the Great Migration, which examined how slaves built community and political understanding while enslaved, so they quickly began to form new associations and institutions when emancipated, including black churches separate from white control. In 2010, Robert E. Wright published a model that explains why slavery was more prevalent in some areas than others (e.g. southern than northern Delaware) and why some firms (individuals, corporations, plantation owners) chose slave labor while others used wage, indentured, or family labor instead.

Historical revisionism arrived when West Indian historian Eric Williams, a Marxist, in Capitalism and Slavery (1944), rejected this moral explanation and argued that abolition was now more profitable, for a century of sugarcane raising had exhausted the soil of the islands, and the plantations had become unprofitable. It was more profitable to sell the slaves to the government than to keep up operations. The 1807 prohibition of the international trade, Williams argued, prevented French expansion on other islands. Meanwhile, British investors turned to Asia, where labor was so plentiful that slavery was unnecessary. Williams went on to argue that slavery played a major role in making Britain prosperous. The high profits from the slave trade, he said, helped finance the Industrial Revolution. Britain enjoyed prosperity because of the capital gained from the unpaid work of slaves.

Since the 1970s numerous historians have challenged Williams from various angles and Gad Heuman has concluded, "More recent research has rejected this conclusion; it is now clear that the colonies of the British Caribbean profited considerably during the Revolutionary and Napoleonic Wars." In his major attack on the Williams's thesis, Seymour Drescher argues that Britain's abolition of the slave trade in 1807 resulted not from the diminishing value of slavery for Britain but instead from the moral outrage of the British voting public. Critics have also argued that slavery remained profitable in the 1830s because of innovations in agriculture so the profit motive was not central to abolition. Richardson (1998) finds Williams's claims regarding the Industrial Revolution are exaggerated, for profits from the slave trade amounted to less than 1% of domestic investment in Britain. Richardson further challenges claims (by African scholars) that the slave trade caused widespread depopulation and economic distress in Africa-indeed that it caused the "underdevelopment" of Africa. Admitting the horrible suffering of slaves, he notes that many Africans benefited directly because the first stage of the trade was always firmly in the hands of Africans. European slave ships waited at ports to purchase cargoes of people who were captured in the hinterland by African dealers and tribal leaders. Richardson finds that the "terms of trade" (how much the ship owners paid for the slave cargo) moved heavily in favor of the Africans after about 1750. That is, indigenous elites inside West and Central Africa made large and growing profits from slavery, thus increasing their wealth and power.

Economic historian Stanley Engerman finds that even without subtracting the associated costs of the slave trade (e.g., shipping costs, slave mortality, mortality of British people in Africa, defense costs) or reinvestment of profits back into the slave trade, the total profits from the slave trade and of West Indian plantations amounted to less than 5% of the British economy during any year of the Industrial Revolution. Engerman's 5% figure gives as much as possible in terms of benefit of the doubt to the Williams argument, not solely because it does not take into account the associated costs of the slave trade to Britain, but also because it carries the full-employment assumption from economics and holds the gross value of slave trade profits as a direct contribution to Britain's national income. Historian Richard Pares, in an article written before Williams's book, dismisses the influence of wealth generated from the West Indian plantations upon the financing of the Industrial Revolution, stating that whatever substantial flow of investment from West Indian profits into industry there was occurred after emancipation, not before.

The history of slavery spans many cultures, nationalities, and religions from ancient times to the present day. However the social, economic, and legal positions of slaves have differed vastly in different systems of slavery in different times and places.

Slavery occurs relatively rarely among hunter-gatherer populations because it develops under conditions of social stratification. Slavery operated in the very first civilizations (such as Sumer in Mesopotamia, which dates back as far as 3500 BCE). Slavery features in the Mesopotamian Code of Hammurabi (c. 1860 BCE), which refers to it as an established institution. Slavery became common within much of Europe during the Early Middle Ages and it continued into the following centuries. The Byzantine-Ottoman wars (1265-1479) and the Ottoman wars in Europe (14th to 20th centuries) resulted in the capture of large numbers of Christian slaves. The Dutch, French, Spanish, Portuguese, British, Arabs and a number of West African kingdoms played a prominent role in the Atlantic slave trade, especially after 1600. The Republic of Ragusa became the first European country to ban the slave trade in 1416. In modern times Denmark-Norway abolished the trade in 1802.

Although slavery is no longer legal anywhere in the world (with the exception of penal labour), human trafficking remains an international problem and an estimated 25-40 million people were enslaved as of 2013, the majority in Asia. During the 1983-2005 Second Sudanese Civil War people were taken into slavery. Evidence emerged in the late 1990s of systematic child-slavery and -trafficking on cacao plantations in West Africa. Slavery continues into the 21st century. Although Mauritania criminalized slavery in August 2007, an estimated up to 600,000 men, women and children, or 20% of the population of Mauritania, are currently enslaved, many of them used as bonded labor. Slavery in the 21st century continues, with the top ten countries with the highest prevalence according to the Global Slavery Index being North Korea, Eritrea, Burundi, the Central African Republic, Afghanistan, Mauritania, South Sudan, Pakistan, Cambodia and Iran. Islamist quasi-states such as the Islamic State of Iraq and the Levant and Boko Haram have abducted and enslaved women and children (often to serve as sex slaves).

Evidence of slavery predates written records, and has existed in many cultures. Mass slavery requires economic surpluses and a high population density to be viable. Due to these factors, the practice of slavery would have only proliferated after the invention of agriculture during the Neolithic Revolution, about 11,000 years ago.

C. 1480 BCE, fugitive slave treaty between Idrimi of Alakakh (now Tell Atchana) and Pillia of Kizzuwatna (now Cilicia).

French historian Fernand Braudel noted that slavery was endemic in Africa and part of the structure of everyday life. "Slavery came in different guises in different societies: there were court slaves, slaves incorporated into princely armies, domestic and household slaves, slaves working on the land, in industry, as couriers and intermediaries, even as traders". During the 16th century, Europe began to outpace the Arab world in the export traffic, with its slave traffic from Africa to the Americas. The Dutch imported slaves from Asia into their colony in South Africa. In 1807 Britain, which held extensive, although mainly coastal, colonial territories on the African continent (including southern Africa), made the international slave trade illegal, as did the United States in 1808.

Slavery in Ethiopia persisted until 1942. The Anti-Slavery Society estimated that there were 2,000,000 slaves in the early 1930s, out of an estimated population of between 8 and 16 million. It was finally abolished by order of emperor Haile Selassie on 26 August 1942.

When British rule was first imposed on the Sokoto Caliphate and the surrounding areas in northern Nigeria at the turn of the 20th century, approximately 2 million to 2.5 million people there were slaves. Slavery in northern Nigeria was finally outlawed in 1936.

Elikia M'bokolo, April 1998, Le Monde diplomatique. Quote: "The African continent was bled of its human resources via all possible routes. Across the Sahara, through the Red Sea, from the Indian Ocean ports and across the Atlantic. At least ten centuries of slavery for the benefit of the Muslim countries (from the ninth to the nineteenth)." He continues: "Four million slaves exported via the Red Sea, another four million through the Swahili ports of the Indian Ocean, perhaps as many as nine million along the trans-Saharan caravan route, and eleven to twenty million (depending on the author) across the Atlantic Ocean"

Zanzibar was once East Africa's main slave-trading port, and under Omani Arabs in the 19th century, as many as 50,000 slaves were passing through the city each year.

Prior to the 16th century, the bulk of slaves exported from Africa were shipped from East Africa to the Arabian peninsula. Zanzibar became a leading port in this trade. Arab slave traders differed from European ones in that they would often conduct raiding expeditions themselves, sometimes penetrating deep into the continent. They also differed in that their market greatly preferred the purchase of female slaves over male ones.

The increased presence of European rivals along the East coast led Arab traders to concentrate on the overland slave caravan routes across the Sahara from the Sahel to North Africa. The German explorer Gustav Nachtigal reported seeing slave caravans departing from Kukawa in Bornu bound for Tripoli and Egypt in 1870. The slave trade represented the major source of revenue for the state of Bornu as late as 1898. The eastern regions of the Central African Republic have never recovered demographically from the impact of 19th-century raids from the Sudan and still have a population density of less than 1 person/km². During the 1870s, European initiatives against the slave trade caused an economic crisis in northern Sudan, precipitating the rise of Mahdist forces. Mahdi's victory created an Islamic state, one that quickly reinstituted slavery.

The Middle Passage, the crossing of the Atlantic to the Americas, endured by slaves laid out in rows in the holds of ships, was only one element of the well-known triangular trade engaged in by Portuguese, Dutch, Danish-Norwegians, French, British and others. Ships having landed slaves in Caribbean ports would take on sugar, indigo, raw cotton, and later coffee, and make for Liverpool, Nantes, Lisbon or Amsterdam. Ships leaving European ports for West Africa would carry printed cotton textiles, some originally from India, copper utensils and bangles, pewter plates and pots, iron bars more valued than gold, hats, trinkets, gunpowder and firearms and alcohol. Tropical shipworms were eliminated in the cold Atlantic waters, and at each unloading, a profit was made.

While talking about the slave trade in East Africa in his journals, "To overdraw its evil is a simple impossibility."

To overdraw its evil is a simple impossibility.

David Livingstone while travelling in the African Great Lakes Region in 1866 described a trail of slaves as such:

19th June 1866 - We passed a woman tied by the neck to a tree and dead, the people of the country explained that she had been unable to keep up with the other slaves in a gang, and her master had determined that she should not become anyone's property if she recovered.
26th June. - ...We passed a slave woman shot or stabbed through the body and lying on the path: a group of men stood about a hundred yards off on one side, and another of the women on the other side, looking on; they said an Arab who passed early that morning had done it in anger at losing the price he had given for her, because she was unable to walk any longer.
27th June 1866 - To-day we came upon a man dead from starvation, as he was very thin. One of our men wandered and found many slaves with slave-sticks on, abandoned by their masters from want of food; they were too weak to be able to speak or say where they had come from; some were quite young.

The strangest disease I have seen in this country seems really to be broken-heartedness, and it attacks free men who have been captured and made slaves... Twenty one were unchained, as now safe; however all ran away at once; but eight with many others still in chains, died in three days after the crossing. They described their only pain in the heart, and placed the hand correctly on the spot, though many think the organ stands high up in the breast-bone.

African states played a role in the slave trade, and slavery was a common practice among Sub Saharan Africans before the involvement of the Arabs, Berbers and Europeans. There were three types: those who were slaves through conquest, those who were slaves due to unpaid debts, or those whose parents gave them as slaves to tribal chiefs. Chieftains would barter their slaves to Arab, Berber, Ottoman or European buyers for rum, spices, cloth or other goods. Selling captives or prisoners was commonly practiced among Africans, Turks, Berbers and Arabs during that era. However, as the Atlantic slave trade increased its demand, local systems which primarily serviced indentured servitude expanded. European slave trading, as a result, was the most pivotal change in the social, economic, cultural, spiritual, religious, political dynamics of the concept of slave trading. It ultimately undermined local economies and political stability as villages' vital labour forces were shipped overseas as slave raids and civil wars became commonplace. Crimes which were previously punishable by some other means became punishable by enslavement.

The kings of Dahomey sold their war captives into transatlantic slavery, who otherwise may have been killed in a ceremony known as the Annual Customs. As one of West Africa's principal slave states, Dahomey became extremely unpopular with neighbouring peoples. Like the Bambara Empire to the east, the Khasso kingdoms depended heavily on the slave trade for their economy. A family's status was indicated by the number of slaves it owned, leading to wars for the sole purpose of taking more captives. This trade led the Khasso into increasing contact with the European settlements of Africa's west coast, particularly the French. Benin grew increasingly rich during the 16th and 17th centuries on the slave trade with Europe; slaves from enemy states of the interior were sold, and carried to the Americas in Dutch and Portuguese ships. The Bight of Benin's shore soon came to be known as the "Slave Coast".

The slave trade is the ruling principle of my people. It is the source and the glory of their wealth...the mother lulls the child to sleep with notes of triumph over an enemy reduced to slavery...

In 1807, under internal and external pressures, the United Kingdom made illegal the international trade in slaves. The Royal Navy was deployed to prevent slavers from the United States, France, Spain, Portugal, Holland, West Africa and Arabia. The King of Bonny (now in Nigeria) allegedly became dissatisfied of the British intervention in stopping slave trading.

We think this trade must go on. That is the verdict of our oracle and the priests. They say that your country, however great, can never stop a trade ordained by God himself.

Joseph Miller states that African buyers would prefer males, but in reality, women and children would be more easily captured as men fled. Those captured would be sold for various reasons such as food, debts, or servitude. Once captured, the journey to the coast killed many and weakened others. Disease engulfed many, and insufficient food damaged those who made it to the coasts. Scurvy was so common that it was known as mal de Luanda (Luanda sickness). The assumption for those who died on the journey died from malnutrition. As food was limited, water may have been just as bad. Dysentery was widespread and poor sanitary conditions at ports did not help. Since supplies were poor, slaves were not equipped with the best clothing that further exposed to more diseases.

If the fear of disease caused terror, the psyche of slaves for being captured was just as terrifying. The most popular assumption for being captured was Europeans were cannibals. Stories and rumours spread that whites captured Africans to eat them. Olaudah Equiano accounts his experience about the sorrow slaves encountered at the ports. He talks about his first moment on a slave ship and asked if he was going to be eaten. Yet, the worst for slaves has only begun, and the journey on the water proved to be more terrifying. For every 100 Africans captured, only 64 would reach the coast, and only about 50 would reach the New World.

Others believe that slavers had a vested interest in capturing rather than killing, and in keeping their captives alive; and that this coupled with the disproportionate removal of males and the introduction of new crops from the Americas ( cassava, maize) would have limited general population decline to particular regions of western Africa around 1760-1810, and in Mozambique and neighbouring areas half a century later. There has also been speculation that within Africa, females were most often captured as brides, with their male protectors being a "bycatch" who would have been killed if there had not been an export market for them.

British explorer Mungo Park encountered a group of slaves when traveling through Mandinka country:

They were all very inquisitive, but they viewed me at first with looks of horror, and repeatedly asked if my countrymen were cannibals. They were very desirous to know what became of the slaves after they had crossed the salt water. I told them that they were employed in cultivation the land; but they would not believe me ... A deeply-rooted idea that the whites purchase negroes for the purpose of devouring them, or of selling them to others that they may be devoured hereafter, naturally makes the slaves contemplate a journey towards the coast with great terror, insomuch that the slatees are forced to keep them constantly in irons, and watch them very closely, to prevent their escape.

During the period from the late 19th century and early 20th century, demand for the labour-intensive harvesting of rubber drove frontier expansion and forced labour. The personal monarchy of Belgian King Leopold II in the Congo Free State saw mass killings and slavery to extract rubber.

Stephanie Smallwood in her book Saltwater Slavery uses Equiano's account on board ships to describe the general thoughts of most slaves.

Then," said I, "how comes it in all our country we never heard of them?" They told me because they lived so very far off. I then asked where were their women? Had they any like themselves? I was told that they had. "And why," said I, "do we not see them?" They answered, because they were left behind. I asked how the vessel could go? They told me they could not tell; but that there was cloth put upon the masts by the help of the ropes I saw, and then the vessel went on; and the white men had some spell or magic they put in the water when they liked, in order to stop the vessel. I was exceedingly amazed at this account, and really thought they were spirits. I there-fore wished much to be from amongst them, for I expected they would sacrifice me; but my wishes were vain-for we were so quartered that it was impossible for any of us to make our escape.

Accounts like these raised many questions as some slaves grew philosophical with their journey. Smallwood points out the challenges for slaves were physical and metaphysical. The physical would be obvious as the challenge to overcome capacity, lack of ship room, and food. The metaphysical was unique as the open sea would challenge African slaves' vision of the ocean as habitable. At essence, the journey on the ocean would prove to be an African's biggest fear that would keep them in awe. Combining this with the lack of knowledge of the sea, Africans would be entering a world of anxiety never seen before. Yet, Europeans were also fearful of the sea, but not to the extent of Africans. One of these dilemmas came with the sense of time. Africans used seasonal weather to predict time and days. The moon was a sense of time, but used like in other cultures. On the sea, Africans used the moon to best count the days, but the sea did not provide seasonal changes for them to know how long they were at sea. Counting the days on a ship was not the main priority, however. Surviving the voyage was the main horror. No one escaped diseases as the close quarters infected everyone including the crew. Death was so common that ships were called tumbeiros or floating tombs. What shocked Africans the most was how death was handled in the ships. Smallwood says the traditions for an African death was delicate and community-based. On ships, bodies would be thrown into the sea. Because the sea represented bad omens, bodies in the sea represented a form of purgatory and the ship a form of hell. In the end, the Africans who made the journey would have survived disease, malnutrition, confined space, close death, and the trauma of the ship.

In Algiers during the time of the Regency of Algiers in North Africa in the 19th century, 1.5 million Christians and Europeans were captured and forced into slavery. This eventually led to the Bombardment of Algiers in 1816 by the British and Dutch, forcing the Dey of Algiers to free many slaves.

The trading of children has been reported in modern Nigeria and Benin. In parts of Ghana, a family may be punished for an offense by having to turn over a virgin female to serve as a sex slave within the offended family. In this instance, the woman does not gain the title or status of "wife". In parts of Ghana, Togo, and Benin, shrine slavery persists, despite being illegal in Ghana since 1998. In this system of ritual servitude, sometimes called trokosi (in Ghana) or voodoosi in Togo and Benin, young virgin girls are given as slaves to traditional shrines and are used sexually by the priests in addition to providing free labor for the shrine.

An article in the Middle East Quarterly in 1999 reported that slavery is endemic in Sudan. Estimates of abductions during the Second Sudanese Civil War range from 14,000 to 200,000 people.

During the Second Sudanese Civil War people were taken into slavery; estimates of abductions range from 14,000 to 200,000. Abduction of Dinka women and children was common. In Mauritania it is estimated that up to 600,000 men, women and children, or 20% of the population, are currently enslaved, many of them used as bonded labor. Slavery in Mauritania was criminalized in August 2007.

During the Darfur conflict that began in 2003, many people were kidnapped by Janjaweed and sold into slavery as agricultural labor, domestic servants and sex slaves.

In Niger, slavery is also a current phenomenon. A Nigerien study has found that more than 800,000 people are enslaved, almost 8% of the population. Niger installed an anti-slavery provision in 2003. In a landmark ruling in 2008, the ECOWAS Community Court of Justice declared that the Republic of Niger failed to protect Hadijatou Mani Koraou from slavery, and awarded Mani CFA 10,000,000 (approximately US$20,000) in reparations.

Sexual slavery and forced labor are common in the Democratic Republic of Congo.

Many pygmies in the Republic of Congo and Democratic Republic of Congo belong from birth to Bantus in a system of slavery.

Evidence emerged in the late 1990s of systematic slavery in cacao plantations in West Africa; see the chocolate and slavery article.

On the night of 14-15 April 2014, a group of militants attacked the Government Girls Secondary School in Chibok, Nigeria. They broke into the school, pretending to be guards, telling the girls to get out and come with them. A large number of students were taken away in trucks, possibly into the Konduga area of the Sambisa Forest where Boko Haram were known to have fortified camps. Houses in Chibok were also burned down in the incident. According to police, approximately 276 children were taken in the attack, of whom 53 had escaped as of 2 May. Other reports said that 329 girls were kidnapped, 53 had escaped and 276 were still missing. The students have been forced to convert to Islam and into marriage with members of Boko Haram, with a reputed " bride price" of ₦2,000 each ($12.50/ £7.50). Many of the students were taken to the neighbouring countries of Chad and Cameroon, with sightings reported of the students crossing borders with the militants, and sightings of the students by villagers living in the Sambisa Forest, which is considered a refuge for Boko Haram.

On 5 May 2014 a video in which Boko Haram leader Abubakar Shekau claimed responsibility for the kidnappings emerged. Shekau claimed that "Allah instructed me to sell them...I will carry out his instructions" and "[s]lavery is allowed in my religion, and I shall capture people and make them slaves." He said the girls should not have been in school and instead should have been married since girls as young as nine are suitable for marriage.

During the Second Libyan Civil War Libyans started capturing some of the Sub-Saharan African migrants trying to get to Europe through Libya and selling them on slave markets. Slaves are often ransomed to their families and in the meantime until ransom can be paid, they may be tortured, forced to work, sometimes worked to death, and eventually they may be executed or left to starve if the payment has not been made after a period of time. Women are often raped and used as sex slaves and sold to brothels.

Many child migrants also suffer from abuse and child rape in Libya.

In Pre-Columbian Mesoamerica the most common forms of slavery were those of prisoners of war and debtors. People unable to pay back debts could be sentenced to work as slaves to the persons owed until the debts were worked off. Warfare was important to Maya society, because raids on surrounding areas provided the victims required for human sacrifice, as well as slaves for the construction of temples. Most victims of human sacrifice were prisoners of war or slaves. Slavery was not usually hereditary; children of slaves were born free. In the Inca Empire, workers were subject to a in lieu of taxes which they paid by working for the government. Each , or extended family, would decide which family member to send to do the work. It is unclear if this labor draft or corvée counts as slavery. The Spanish adopted this system, particularly for their silver mines in Bolivia.

Other slave-owning societies and tribes of the New World were, for example, the Tehuelche of Patagonia, the Comanche of Texas, the Caribs of Dominica, the Tupinambá of Brazil, the fishing societies, such as the Yurok, that lived along the coast from what is now Alaska to California, the Pawnee and Klamath. Many of the indigenous peoples of the Pacific Northwest Coast, such as the Haida and Tlingit, were traditionally known as fierce warriors and slave-traders, raiding as far as California. Slavery was hereditary, the slaves being prisoners of war. Among some Pacific Northwest tribes about a quarter of the population were slaves. One slave narrative was composed by an Englishman, John R. Jewitt, who had been taken alive when his ship was captured in 1802; his memoir provides a detailed look at life as a slave, and asserts that a large number were held.

During the period from the late 19th century and early 20th century, demand for the labor-intensive harvesting of rubber drove frontier expansion and slavery in Latin America and elsewhere. Indigenous peoples were enslaved as part of the rubber boom in Ecuador, Peru, Colombia, and Brazil. In Central America, rubber tappers participated in the enslavement of the indigenous Guatuso-Maleku people for domestic service.

Slavery was a mainstay of the Brazilian colonial economy, especially in mining and sugarcane production. 35.3% of all slaves involved in the Atlantic Slave trade went to Brazil. 4 million slaves were obtained by Brazil, 1.5 million more than any other country. Starting around 1550, the Portuguese began to trade African slaves to work the sugar plantations, once the native Tupi people deteriorated. Although Portuguese Prime Minister Sebastião José de Carvalho e Melo, 1st Marquis of Pombal abolished slavery in mainland Portugal on 12 February 1761, slavery continued in her overseas colonies. Slavery was practiced among all classes. Slaves were owned by upper and middle classes, by the poor, and even by other slaves.

From São Paulo, the Bandeirantes, adventurers mostly of mixed Portuguese and native ancestry, penetrated steadily westward in their search for Indian slaves. Along the Amazon river and its major tributaries, repeated slaving raids and punitive attacks left their mark. One French traveler in the 1740s described hundreds of miles of river banks with no sign of human life and once-thriving villages that were devastated and empty. In some areas of the Amazon Basin, and particularly among the Guarani of southern Brazil and Paraguay, the Jesuits had organized their Jesuit Reductions along military lines to fight the slavers. In the mid-to-late 19th century, many Amerindians were enslaved to work on rubber plantations.

Escaped slaves formed Maroon communities which played an important role in the histories of Brazil and other countries such as Suriname, Puerto Rico, Cuba, and Jamaica. In Brazil, the Maroon villages were called palenques or quilombos. Maroons survived by growing vegetables and hunting. They also raided plantations. At these attacks, the maroons would burn crops, steal livestock and tools, kill slavemasters, and invite other slaves to join their communities.

Jean-Baptiste Debret, a French painter who was active in Brazil in the first decades of the 19th century, started out with painting portraits of members of the Brazilian Imperial family, but soon became concerned with the slavery of both blacks and indigenous inhabitants. His paintings on the subject (two appear on this page) helped bring attention to the subject in both Europe and Brazil itself.

The Clapham Sect, a group of evangelical reformers, campaigned during much of the 19th century for Britain to use its influence and power to stop the traffic of slaves to Brazil. Besides moral qualms, the low cost of slave-produced Brazilian sugar meant that British colonies in the West Indies were unable to match the market prices of Brazilian sugar, and each Briton was consuming 16 pounds (7 kg) of sugar a year by the 19th century. This combination led to intensive pressure from the British government for Brazil to end this practice, which it did by steps over several decades.

Brazil's 1877-78 Grande Seca (Great Drought) in the cotton-growing northeast led to major turmoil, starvation, poverty and internal migration. As wealthy plantation holders rushed to sell their slaves south, popular resistance and resentment grew, inspiring numerous emancipation societies. They succeeded in banning slavery altogether in the province of Ceará by 1884. Slavery was legally ended nationwide on 13 May by the ("Golden Law") of 1888. It was an institution in decadence at these times, as since the 1880s the country had begun to use European immigrant labor instead. Brazil was the last nation in the Western Hemisphere to abolish slavery.

Slavery was commonly used in the parts of the Caribbean controlled by France and the British Empire. The Lesser Antilles islands of Barbados, St. Kitts, Antigua, Martinique and Guadeloupe, which were the first important slave societies of the Caribbean, began the widespread use of African slaves by the end of the 17th century, as their economies converted from sugar production.

England had multiple sugar islands in the Caribbean, especially Jamaica, Barbados, Nevis, and Antigua, which provided a steady flow of sugar sales; slave labor produced the sugar. By the 1700s, there were more slaves in Barbados than all the colonies combined. Since Barbados did not have many mountains, the British were able to clear land for sugar cane. Indentured servants were initially sent to Barbados to work in the sugar fields. These indentured servants were treated so poorly that future indentured servants stopped going to Barbados, and there were not enough people to work the fields. This is when the British started bringing in African slaves. It was important for the slaves to be in Barbados because sugar had become a necessity for most people and the demand for it was high.

An important result of Britain's victory in the War of the Spanish Succession (1702-1714) was enlarging its role in the slave trade. Of special importance was the successful secret negotiation with France to obtain thirty-year monopoly on the Spanish slave trade, called the Queen Anne of Great Britain also allowed her North American colonies like Virginia to make laws that promoted black slavery. Anne had secretly negotiated with France to get its approval regarding the Asiento. She boasted to Parliament of her success in taking the Asiento away from France and London celebrated her economic coup. Most of the slave trade involved sales to Spanish colonies in the Caribbean, and to Mexico, as well as sales to British colonies in the Caribbean and in North America. Historian Vinita Ricks says the agreement allotted Queen Anne "22.5% (and King Philip V, of Spain 28%) of all profits collected for her personal fortune." Ricks concludes that the Queen's "connection to slave trade revenue meant that she was no longer a neutral observer. She had a vested interest in what happened on slave ships."

By 1778, the French were importing approximately 13,000 Africans for enslavement yearly to the French West Indies.

To regularise slavery, in 1685 Louis XIV had enacted the , which accorded certain human rights to slaves and responsibilities to the master, who was obliged to feed, clothe and provide for the general well-being of his slaves. Free blacks owned one-third of the plantation property and one-quarter of the slaves in Saint Domingue (later Haiti). Slavery in the French First Republic was abolished on 4 February 1794. When it became clear that Napoleon intended to re-establish slavery in Haiti, Dessalines and Pétion switched sides, in October 1802. On 1 January 1804, Jean-Jacques Dessalines, the new leader under the dictatorial 1801 constitution, declared Haiti a free republic. Thus Haiti became the second independent nation in the Western Hemisphere, after the United States, and the only successful slave rebellion in world history.

Whitehall in England announced in 1833 that slaves in its territories would be totally freed by 1840. In the meantime, the government told slaves they had to remain on their plantations and would have the status of "apprentices" for the next six years.

In Port-of-Spain, Trinidad, on 1 August 1834, an unarmed group of mainly elderly Negroes being addressed by the Governor at Government House about the new laws, began chanting: "Pas de six ans. Point de six ans" ("Not six years. No six years"), drowning out the voice of the Governor. Peaceful protests continued until a resolution to abolish apprenticeship was passed and de facto freedom was achieved. Full emancipation for all was legally granted ahead of schedule on 1 August 1838, making Trinidad the first British colony with slaves to completely abolish slavery.

In late August 1619, the frigate , a privateer ship owned by Robert Rich, 2nd Earl of Warwick, but flying a Dutch flag arrived at Point Comfort, Virginia (several miles downstream from the colony of Jamestown, Virginia) with the first recorded slaves from Africa to Virginia. The approximately 20 Africans were from the present-day Angola. They had been removed by the White Lion's crew from a Portuguese slave ship, the São João Bautista.

Only a fraction of the enslaved Africans brought to the New World came to British North America, perhaps as little as 5% of the total. The vast majority of slaves were sent to the Caribbean sugar colonies, Brazil, or Spanish America.

By the 1680s, with the consolidation of England's Royal African Company, enslaved Africans were arriving in English colonies in larger numbers, and the institution continued to be protected by the British government. Colonists now began purchasing slaves in larger numbers.

1640: Virginia courts sentence John Punch to lifetime slavery, marking the earliest legal sanctioning of slavery in English colonies.

1641: Massachusetts legalizes slavery.

1650: Connecticut legalizes slavery.

1654: Virginia sanctions "the right of Negros to own slaves of their own race" after African Anthony Johnson, former indentured servant, sued to have fellow African John Casor declared not an indentured servant but "slave for life."

1661: Virginia officially recognizes slavery by statute.

1662: A Virginia statute declares that children born would have the same status as their mother.

1663: Maryland legalizes slavery.

1664: Slavery is legalized in New York and New Jersey.

1670: Carolina (later, South Carolina and North Carolina) is founded mainly by planters from the overpopulated British sugar island colony of Barbados, who brought relatively large numbers of African slaves from that island.

The shift from indentured servants to African slaves was prompted by a dwindling class of former servants who had worked through the terms of their indentures and thus became competitors to their former masters. These newly freed servants were rarely able to support themselves comfortably, and the tobacco industry was increasingly dominated by large planters. This caused domestic unrest culminating in Bacon's Rebellion. Eventually, chattel slavery became the norm in regions dominated by plantations.

Several local slave rebellions took place during the 17th and 18th centuries: Gloucester County, Virginia Revolt (1663); New York Slave Revolt of 1712; Stono Rebellion (1739); and New York Slave Insurrection of 1741.

Within the British Empire, the Massachusetts courts began to follow England when, in 1772, England became the first country in the world to outlaw the slave trade within its borders (see Somerset v Stewart) followed by the Knight v. Wedderburn decision in Scotland in 1778. Between 1764 and 1774, seventeen slaves appeared in Massachusetts courts to sue their owners for freedom. In 1766, John Adams' colleague Benjamin Kent won the first trial in the present-day United States to free a slave (Slew vs. Whipple).

The Republic of Vermont banned slavery in its constitution of 1777 and continued the ban when it entered the United States in 1791. Through the Northwest Ordinance of 1787 under the Congress of the Confederation, slavery was prohibited in the territories north west of the Ohio River. By 1804, abolitionists succeeded in passing legislation that ended legal slavery in every northern state (with slaves above a certain age legally transformed to indentured servants). Congress banned the international importation or export of slaves on 1 January 1808; but not the internal slave trade.

Despite the actions of abolitionists, free blacks were subject to racial segregation in the Northern states. While England did not ban slavery in present-day Canada until 1833, free blacks found refugee and liberty there after the America Revolution and again after the War of 1812. Slavery in Canada was largely ended by judicial court decisions by the early nineteenth century. Refugees from slavery fled the South across the Ohio River to the North via the Underground Railroad. Midwestern state governments asserted States Rights arguments to refuse federal jurisdiction over fugitives. Some juries exercised their right of jury nullification and refused to convict those indicted under the Fugitive Slave Act of 1850.

After the passage of the Kansas-Nebraska Act in 1854, armed conflict broke out in Kansas Territory, where the question of whether it would be admitted to the Union as a slave state or a free state had been left to the inhabitants. The radical abolitionist John Brown was active in the mayhem and killing in " Bleeding Kansas." The true turning point in public opinion is better fixed at the Lecompton Constitution fraud. Pro-slavery elements in Kansas had arrived first from Missouri and quickly organized a territorial government that excluded abolitionists. Through the machinery of the territory and violence, the pro-slavery faction attempted to force an unpopular pro-slavery constitution through the state. This infuriated Northern Democrats, who supported popular sovereignty, and was exacerbated by the Buchanan administration reneging on a promise to submit the constitution to a referendum-which would surely fail. Anti-slavery legislators took office under the banner of the newly formed Republican Party. The Supreme Court in the Dred Scott decision of 1857 asserted that one could take one's property anywhere, even if one's property was chattel and one crossed into a free territory. It also asserted that African Americans could not be federal citizens. Outraged critics across the North denounced these episodes as the latest of the Slave Power (the politically organized slave owners) taking more control of the nation.

The slave population in the United States stood at four million. Ninety-five percent of blacks lived in the South, comprising one third of the population there as opposed to 1% of the population of the North. The central issue in politics in the 1850s involved the extension of slavery into the western territories, which settlers from the Northern states opposed. The Whig Party split and collapsed on the slavery issue, to be replaced in the North by the new Republican Party, which was dedicated to stopping the expansion of slavery. Republicans gained a majority in every northern state by absorbing a faction of anti-slavery Democrats, and warning that slavery was a backward system that undercut democracy and economic modernization. Numerous compromise proposals were put forward, but they all collapsed. A majority of Northern voters were committed to stopping the expansion of slavery, which they believed would ultimately end slavery. Southern voters were overwhelmingly angry that they were being treated as second-class citizens. In the election of 1860, the Republicans swept Abraham Lincoln into the Presidency and his party took control (with only 39.8% of the popular vote) and legislators into Congress. The states of the deep South, convinced that the economic power of what they called " King Cotton" would overwhelm the North and win support from Europe voted to seceded from the U.S. (the Union). They formed the Confederate States of America, based on the promise of maintaining slavery. War broke out in April 1861, as both sides sought wave after wave of enthusiasm among young men volunteering to form new regiments and new armies. In the North, the main goal was to preserve the union as an expression of American nationalism.

By 1862 most northern leaders realized that the mainstay of Southern secession, slavery, had to be attacked head-on. All the border states rejected President Lincoln's proposal for compensated emancipation. However, by 1865 all had begun the abolition of slavery, except Kentucky and Delaware. The Emancipation Proclamation was an executive order issued by Lincoln on 1 January 1863. In a single stroke, it changed the legal status, as recognized by the U.S. government, of 3 million slaves in designated areas of the Confederacy from "slave" to "free." It had the practical effect that as soon as a slave escaped the control of the Confederate government, by running away or through advances of federal troops, the slave became legally and actually free. Plantation owners, realizing that emancipation would destroy their economic system, sometimes moved their slaves as far as possible out of reach of the Union army. By June 1865, the Union Army controlled all of the Confederacy and liberated all of the designated slaves. The owners were never compensated. Over 200,000 free blacks and newly freed slaves fought for the Union in the Army and Navy, thereby validating their claims to full citizenship.

The severe dislocations of war and Reconstruction had a severe negative impact on the black population, with a large amount of sickness and death. After liberation, many of the Freedmen remained on the same plantation. Others fled or crowded into refugee camps operated by the Freedmen's Bureau. The Bureau provided food, housing, clothing, medical care, church services, some schooling, legal support, and arranged for labor contracts. Fierce debates about the rights of the Freedmen, and of the defeated Confederates, often accompanied by killings of black leaders, marked the Reconstruction Era, 1863-77.

Slavery was never reestablished, but after 1877, white Democrats took control of all the southern states and blacks lost nearly all the political power they had achieved during Reconstruction. By 1900 they also lost the right to vote. They had become second class citizens. The great majority lived in the rural South in poverty working as laborers, sharecroppers or tenant farmers; a small proportion owned their own land. The black churches, especially the Baptist Church, was the center of community activity and leadership.

Slavery in the Middle East first developed out of the slavery practices of the Ancient Near East, and these practices were radically different at times, depending on social-political factors such as the Arab slave trade. Two rough estimates by scholars of the number of slaves held over twelve centuries in Muslim lands are 11.5 million and 14 million.

Under Sharia (Islamic law), children of slaves or prisoners of war could become slaves but only non-Muslims. Manumission of a slave was encouraged as a way of expiating sins. Many early converts to Islam, such as Bilal ibn Rabah al-Habashi, were the poor and former slaves. In theory, slavery in Islamic law does not have a racial or color component, although this has not always been the case in practice.

Bernard Lewis writes: "In one of the sad paradoxes of human history, it was the humanitarian reforms brought by Islam that resulted in a vast development of the slave trade inside, and still more outside, the Islamic empire." He notes that the Islamic injunctions against the enslavement of Muslims led to massive importation of slaves from the outside. According to Patrick Manning, Islam by recognizing and codifying the slavery seems to have done more to protect and expand slavery than the reverse.

Slavery was a legal and important part of the economy of the Ottoman Empire and Ottoman society until the slavery of Caucasians was banned in the early 19th century, although slaves from other groups were allowed. In Constantinople (present-day Istanbul), the administrative and political center of the Empire, about a fifth of the population consisted of slaves in 1609. Even after several measures to ban slavery in the late 19th century, the practice continued largely unfazed into the early 20th century. As late as 1908, female slaves were still sold in the Ottoman Empire. Sexual slavery was a central part of the Ottoman slave system throughout the history of the institution.

A member of the Ottoman slave class, called a in Turkish, could achieve high status. Harem guards and janissaries are some of the better-known positions a slave could hold, but slaves were actually often at the forefront of Ottoman politics. The majority of officials in the Ottoman government were bought slaves, raised free, and integral to the success of the Ottoman Empire from the 14th century into the 19th. Many officials themselves owned a large number of slaves, although the Sultan himself owned by far the largest amount. By raising and specially training slaves as officials in palace schools such as Enderun, the Ottomans created administrators with intricate knowledge of government and fanatic loyalty.

Ottomans practiced , a sort of "blood tax" or "child collection", young Christian boys from the Balkans and Anatolia were taken from their homes and families, brought up as Muslims, and enlisted into the most famous branch of the , the Janissaries, a special soldier class of the Ottoman army that became a decisive faction in the Ottoman invasions of Europe.

During the various 18th and 19th century persecution campaigns against Christians as well as during the culminating Assyrian, Armenian and Greek genocides of World War I, many indigenous Armenian, Assyrian and Greek Christian women and children were carried off as slaves by the Ottoman Turks and their Kurdish allies. Henry Morgenthau, Sr., U.S. Ambassador in Constantinople from 1913 to 1916, reports in his Ambassador Morgenthau's Story that there were gangs trading white slaves during his term in Constantinople. He also reports that Armenian girls were sold as slaves during the Armenian Genocide.

The Arab or Islamic slave trade lasted much longer than the Atlantic or European slave trade: "It began in the middle of the seventh century and survives today in Mauritania and Sudan. With the Islamic slave trade, we're talking of 14 centuries rather than four." Further, "whereas the gender ratio of slaves in the Atlantic trade was two males to every female, in the Islamic trade, it was two females to every male," according to Ronald Segal

According to media reports from late 2014 the Islamic State of Iraq and the Levant (ISIL) was selling Yazidi and Christian women as slaves. According to Haleh Esfandiari of the Woodrow Wilson International Center for Scholars, after ISIL militants have captured an area "[t]hey usually take the older women to a makeshift slave market and try to sell them." In mid-October 2014, the UN estimated that 5,000 to 7,000 Yazidi women and children were abducted by ISIL and sold into slavery. In the digital magazine , ISIL claimed religious justification for enslaving Yazidi women whom they consider to be from a heretical sect. ISIL claimed that the Yazidi are idol worshipers and their enslavement is part of the old shariah practice of spoils of war. According to The Wall Street Journal, ISIL appeals to apocalyptic beliefs and claims "justification by a Hadith that they interpret as portraying the revival of slavery as a precursor to the end of the world".

ISIL announced the revival of slavery as an institution. In 2015 the official slave prices set by ISIL were following:

Children aged 1 to 9 were sold for 200,000 dinars ($169).

Women and children 10 to 20 years old for 150,000 dinars ($127).

Women 20 to 30 years old for 100,000 dinar ($85).

Women 30 to 40 years old are 75,000 dinar ($63).

Women 40 to 50 years old for 50,000 dinar ($42).

However some slaves have been sold for as little as a pack of cigarettes. Sex slaves were sold to Saudi Arabia, other Persian Gulf states and Turkey.

Slavery has existed all throughout Asia, and forms of slavery still exist today.

Scholars differ as to whether or not slaves and the institution of slavery existed in ancient India. These English words have no direct, universally accepted equivalent in Sanskrit or other Indian languages, but some scholars translate the word , mentioned in texts like Manu Smriti, as slaves. Ancient historians who visited India offer the closest insights into the nature of Indian society and slavery in other ancient civilizations. For example, the Greek historian Arrian, who chronicled India about the time of Alexander the Great, wrote in his Indika,

The Indians do not even use aliens as slaves, much less a countryman of their own.

Qin dynasty (221-206 BC) Men sentenced to castration became eunuch slaves of the Qin dynasty state and as a result they were made to do forced labor, on projects like the Terracotta Army. The Qin government confiscated the property and enslaved the families of those who received castration as a punishment for rape.
Slaves were deprived of their rights and connections to their families.

Han dynasty (206 BC - 220 AD) One of Emperor Gao's first acts was to set free from slavery agricultural workers who were enslaved during the Warring States period, although domestic servants retained their status.

Men punished with castration during the Han dynasty were also used as slave labor.

Deriving from earlier Legalist laws, the Han dynasty set in place rules that the property of and families of criminals doing three years of hard labor or sentenced to castration were to have their families seized and kept as property by the government.

During the millennium long Chinese domination of Vietnam, Vietnam was a great source of slave girls who were used as sex slaves in China. The slave girls of Viet were even eroticized in Tang dynasty poetry.

The Islamic invasions, starting in the 8th century, also resulted in hundreds of thousands of Indians being enslaved by the invading armies, one of the earliest being the armies of the Umayyad commander Muhammad bin Qasim. Qutb-ud-din Aybak, a Turkic slave of Muhammad Ghori rose to power following his master's death. For almost a century, his descendants ruled North-Central India in form of Slave Dynasty. Several slaves were also brought to India by the Indian Ocean trades; for example, the Siddi are descendants of Bantu slaves brought to India by Arab and Portuguese merchants.

Andre Wink summarizes the slavery in 8th and 9th century India as follows,

(During the invasion of Muhammad al-Qasim), invariably numerous women and children were enslaved. The sources insist that now, in dutiful conformity to religious law, 'the one-fifth of the slaves and spoils' were set apart for the caliph's treasury and despatched to Iraq and Syria. The remainder was scattered among the army of Islam. At Rūr, a random 60,000 captives reduced to slavery. At Brahamanabad 30,000 slaves were allegedly taken. At Multan 6,000. Slave raids continued to be made throughout the late Umayyad period in Sindh, but also much further into Hind, as far as Ujjain and Malwa. The Abbasid governors raided Punjab, where many prisoners and slaves were taken.

In the early 11th century Tarikh al-Yamini, the Arab historian Al-Utbi recorded that in 1001 the armies of Mahmud of Ghazna conquered Peshawar and Waihand (capital of Gandhara) after Battle of Peshawar (1001), "in the midst of the land of Hindustan", and captured some 100,000 youths. Later, following his twelfth expedition into India in 1018-19, Mahmud is reported to have returned with such a large number of slaves that their value was reduced to only two to ten dirhams each. This unusually low price made, according to Al-Utbi, "merchants [come] from distant cities to purchase them, so that the countries of Central Asia, Iraq and Khurasan were swelled with them, and the fair and the dark, the rich and the poor, mingled in one common slavery". Elliot and Dowson refer to "five hundred thousand slaves, beautiful men and women.". Later, during the Delhi Sultanate period (1206-1555), references to the abundant availability of low-priced Indian slaves abound. Levi attributes this primarily to the vast human resources of India, compared to its neighbors to the north and west (India's Mughal population being approximately 12 to 20 times that of Turan and Iran at the end of the 16th century).

Slavery and empire-formation tied in particularly well with iqta and it is within this context of Islamic expansion that elite slavery was later commonly found. It became the predominant system in North India in the thirteenth century and retained considerable importance in the fourteenth century. Slavery was still vigorous in fifteenth-century Bengal, while after that date it shifted to the Deccan where it persisted until the seventeenth century. It remained present to a minor extent in the Mughal provinces throughout the seventeenth century and had a notable revival under the Afghans in North India again in the eighteenth century.

The Delhi sultanate obtained thousands of slaves and eunuch servants from the villages of Eastern Bengal (a widespread practice which Mughal emperor Jahangir later tried to stop). Wars, famines, pestilences drove many villagers to sell their children as slaves. The Muslim conquest of Gujarat in Western India had two main objectives. The conquerors demanded and more often forcibly wrested both land owned by Hindus and Hindu women. Enslavement of women invariably led to their conversion to Islam. In battles waged by Muslims against Hindus in Malwa and Deccan plateau, a large number of captives were taken. Muslim soldiers were permitted to retain and enslave POWs as plunder.

The first Bahmani sultan, Alauddin Bahman Shah is noted to have captured 1,000 singing and dancing girls from Hindu temples after he battled the northern Carnatic chieftains. The later Bahmanis also enslaved civilian women and children in wars; many of them were converted to Islam in captivity. About the Mughal empire, W.H. Moreland observed, "it became a fashion to raid a village or group of villages without any obvious justification, and carry off the inhabitants as slaves."

During the rule of Shah Jahan, many peasants were compelled to sell their women and children into slavery to meet the land revenue demand. Slavery was officially abolished in British India by the Indian Slavery Act, 1843. However, in modern India, Pakistan and Nepal, there are millions of bonded laborers, who work as slaves to pay off debts.

The Tang dynasty purchased Western slaves from the Radanite Jews. Tang Chinese soldiers and pirates enslaved Koreans, Turks, Persians, Indonesians, and people from Inner Mongolia, Central Asia, and northern India. The greatest source of slaves came from southern tribes, including Thais and aboriginals from the southern provinces of Fujian, Guangdong, Guangxi, and Guizhou. Malays, Khmers, Indians, and black Africans were also purchased as slaves in the Tang dynasty. Slavery was prevalent until the late 19th century and early 20th century China. All forms of slavery have been illegal in China since 1910.

Slavery in Japan was, for most of its history, indigenous, since the export and import of slaves was restricted by Japan being a group of islands. In late-16th-century Japan, slavery was officially banned; but forms of contract and indentured labor persisted alongside the period penal codes' forced labor. During the Second Sino-Japanese War and the Pacific War, the Japanese military used millions of civilians and prisoners of war from several countries as forced laborers.

In Korea, slavery was officially abolished with the Gabo Reform of 1894. During the Joseon period, in times of poor harvest and famine, many peasants voluntarily sold themselves into the nobi system in order to survive.

In Southeast Asia, there was a large slave class in Khmer Empire who built the enduring monuments in Angkor Wat and did most of the heavy work. Between the 17th and the early 20th centuries one-quarter to one-third of the population of some areas of Thailand and Burma were slaves. By the 19th century, Bhutan had developed a slave trade with Sikkim and Tibet, also enslaving British subjects and Brahmins. According to the International Labour Organization (ILO), during the early 21st century an estimated 800,000 people are subject to forced labor in Myanmar.

Slavery in pre-Spanish Philippines was practiced by the tribal Austronesian peoples who inhabited the culturally diverse islands. The neighbouring Muslim states conducted slave raids from the 1600s into the 1800s in coastal areas of the Gulf of Thailand and the Philippine islands. Slaves in Toraja society in Indonesia were family property. People would become slaves when they incurred a debt. Slaves could also be taken during wars, and slave trading was common. Torajan slaves were sold and shipped out to Java and Siam. Slaves could buy their freedom, but their children still inherited slave status. Slavery was abolished in 1863 in all Dutch colonies.

Records of slavery in Ancient Greece go as far back as Mycenaean Greece. The origins are not known, but it appears that slavery became an important part of the economy and society only after the establishment of cities. Slavery was common practice and an integral component of ancient Greece, as it was in other societies of the time, including ancient Israel. It is estimated that in Athens, the majority of citizens owned at least one slave. Most ancient writers considered slavery not only natural but necessary, but some isolated debate began to appear, notably in Socratic dialogues. The Stoics produced the first condemnation of slavery recorded in history.

During the 8th and the 7th centuries BC, in the course of the two Messenian Wars, the Spartans reduced an entire population to a pseudo-slavery called . According to Herodotus (IX, 28-29), helots were seven times as numerous as Spartans. Following several helot revolts around the year 600 BC, the Spartans restructured their city-state along authoritarian lines, for the leaders decided that only by turning their society into an armed camp could they hope to maintain control over the numerically dominant helot population. In some Ancient Greek city-states, about 30% of the population consisted of slaves, but paid and slave labor seem to have been equally important.

Romans inherited the institution of slavery from the Greeks and the Phoenicians. As the Roman Republic expanded outward, it enslaved entire populations, thus ensuring an ample supply of laborers to work in Rome's farms, quarries and households. The people subjected to Roman slavery came from all over Europe and the Mediterranean. Such oppression by an elite minority eventually led to slave revolts; the Third Servile War led by Spartacus was the most famous and severe. Greeks, Berbers, Germans, Britons, Slavs, Thracians, Gauls (or Celts), Jews, Arabs and many more ethnic groups were enslaved to be used for labor, and also for amusement (e.g. gladiators and sex slaves). If a slave ran away, they were liable to be crucified.

The overall impact of slavery on the Italian genetics was insignificant though, because the slaves imported in Italy were native Europeans, and very few if any of them had extra European origin. This has been further confirmed by recent biochemical analysis of 166 skeletons from three non-elite imperial-era cemeteries in the vicinity of Rome (where the bulk of the slaves lived), which shows that only 1 individual definitely came from outside of Europe (North Africa), and another 2 possibly did, but results are inconclusive. In the rest of the Italian peninsula, the amount of non European slaves was definitively much lower than that.

The chaos of invasion and frequent warfare also resulted in victorious parties taking slaves throughout Europe in the early Middle Ages. St. Patrick, himself captured and sold as a slave, protested against an attack that enslaved newly baptized Christians in his "Letter to the Soldiers of Coroticus". As a commonly traded commodity, like cattle, slaves could become a form of internal or trans-border currency. Slavery during the Early Middle Ages had several distinct sources.

The Vikings raided across Europe, but took the most slaves in raids on the British Isles and in Eastern Europe. While the Vikings kept some slaves as servants, known as , they sold most captives in the Byzantine or Islamic markets. In the West, their target populations were primarily English, Irish, and Scottish, while in the East they were mainly Slavs. The Viking slave-trade slowly ended in the 11th century, as the Vikings settled in the European territories they had once raided. They converted serfs to Christianity and themselves merged with the local populace.

In central Europe, specifically the Frankish/German/Holy Roman Empire of Charlemagne, raids and wars to the east generated a steady supply of slaves from the Slavic captives of these regions. Because of high demand for slaves in the wealthy Muslim empires of Northern Africa, Spain, and the Near East, especially for slaves of European descent, a market for these slaves rapidly emerged. So lucrative was this market that it spawned an economic boom in central and western Europe, today known as the Carolingian Renaissance. This boom period for slaves stretched from the early Muslim conquests to the High Middle Ages but declined in the later Middle Ages as the Islamic Golden Age waned.

Medieval Spain and Portugal saw almost constant warfare between Muslims and Christians. Al-Andalus sent periodic raiding expeditions to loot the Iberian Christian kingdoms, bringing back booty and slaves. In a raid against Lisbon, Portugal in 1189, for example, the Almohad caliph Yaqub al-Mansur took 3,000 female and child captives. In a subsequent attack upon Silves, Portugal in 1191, his governor of Córdoba took 3,000 Christian slaves.

The Byzantine-Ottoman wars and the Ottoman wars in Europe resulted in the taking of large numbers of Christian slaves and using or selling them in the Islamic world too. After the battle of Lepanto the victors freed approximately 12,000 Christian galley slaves from the Ottoman fleet.

Similarly, Christians sold Muslim slaves captured in war. The Order of the Knights of Malta attacked pirates and Muslim shipping, and their base became a centre for slave trading, selling captured North Africans and Turks. Malta remained a slave market until well into the late 18th century. One thousand slaves were required to man the galleys (ships) of the Order.

Poland banned slavery in the 15th century; in Lithuania, slavery was formally abolished in 1588; the institution was replaced by the second enserfment. Slavery remained a minor institution in Russia until 1723, when Peter the Great converted the household slaves into house serfs. Russian agricultural slaves were formally converted into serfs earlier, in 1679. The escaped Russian serfs and kholops formed autonomous communities in the southern steppes, where they became known as Cossacks (meaning "outlaws").

Capture in war, voluntary servitude and debt slavery became common within the British Isles before 1066. Slaves were routinely bought and sold. Running away was also common and slavery was never a major economic factor in the British Isles during the Middle Ages. Ireland and Denmark provided markets for captured Anglo-Saxon and Celtic slaves. Pope Gregory I reputedly made the pun, Non Angli, sed Angeli ("Not Angles, but Angels"), after a response to his query regarding the identity of a group of fair-haired Angles, slave children whom he had observed in the marketplace. After the Norman Conquest, the law no longer supported chattel slavery and slaves became part of the larger body of serfs.

Barbary pirates and Maltese corsairs both raided for slaves and purchased slaves from European merchants, often the Radhanites, one of the few groups who could easily move between the Christian and Islamic worlds.

In the late Middle Ages, from 1100 to 1500, the European slave-trade continued, though with a shift from being centered among the Western Mediterranean Islamic nations to the Eastern Christian and Muslim states. The city-states of Venice and Genoa controlled the Eastern Mediterranean from the 12th century and the Black Sea from the 13th century. They sold both Slavic and Baltic slaves, as well as Georgians, Turks, and other ethnic groups of the Black Sea and Caucasus. The sale of European slaves by Europeans slowly ended as the Slavic and Baltic ethnic groups Christianized by the Late Middle Ages. European slaves did not pass on an inherited status and was thus more akin to forced labor, or indentured servitude.

From the 1440s into the 18th century, Europeans from Italy, Spain, Portugal, France, and England were sold into slavery by North Africans, as described in the book "Christian Slaves, Muslim Masters". This same book states that "white slavery had been minimised or ignored because academics preferred to treat Europeans as evil colonialists rather than as victims." and likely overestimates the number of slaves taken. In 1575, the Tatars captured over 35,000 Ukrainians; a 1676 raid took almost 40,000. About 60,000 Ukrainians were captured in 1688; some were ransomed, but most were sold into slavery. Some of the Roma people were enslaved over five centuries in Romania until abolition in 1864 (see Slavery in Romania).

The Mongol invasions and conquests in the 13th century also resulted in taking numerous captives into slavery. The Mongols enslaved skilled individuals, women and children and marched them to Karakorum or Sarai, whence they were sold throughout Eurasia. Many of these slaves were shipped to the slave market in Novgorod.

Slave commerce during the Late Middle Ages was mainly in the hands of Venetian and Genoese merchants and cartels, who were involved in the slave trade with the Golden Horde. In 1382 the Golden Horde under Khan Tokhtamysh sacked Moscow, burning the city and carrying off thousands of inhabitants as slaves. Between 1414 and 1423, some 10,000 eastern European slaves were sold in Venice. Genoese merchants organized the slave trade from the Crimea to Mamluk Egypt. For years, the Khanates of Kazan and Astrakhan routinely made raids on Russian principalities for slaves and to plunder towns. Russian chronicles record about 40 raids by Kazan Khans on the Russian territories in the first half of the 16th century.

In 1441 Haci I Giray declared independence from the Golden Horde and established the Crimean Khanate. For a long time, until the early 18th century, the khanate maintained an extensive slave-trade with the Ottoman Empire and the Middle East. In a process called the "harvesting of the steppe" they enslaved many Slavic peasants. About 30 major Tatar raids were recorded into Muscovite territories between 1558 and 1596.

Moscow was repeatedly a target. In 1521, the combined forces of Crimean Khan Mehmed Giray and his Kazan allies attacked the city and captured thousands of slaves. In 1571, the Crimean Tatars attacked and sacked Moscow, burning everything but the Kremlin and taking thousands of captives as slaves. In Crimea, about 75% of the population consisted of slaves.

In the Viking era beginning circa 793, the Norse raiders often captured and enslaved militarily weaker peoples they encountered. The Nordic countries called their slaves ( Old Norse: Þræll). The thralls were mostly from Western Europe, among them many Franks, Frisians, Anglo-Saxons, and both Irish and Britonnic Celts. Many Irish slaves travelled in expeditions for the colonization of Iceland. The Norse also took German, Baltic, Slavic and Latin slaves. The slave trade was one of the pillars of Norse commerce during the 6th through 11th centuries. The 10th-century Persian traveller Ibn Rustah described how Swedish Vikings, the Varangians or Rus, terrorized and enslaved the Slavs taken in their raids along the Volga River. The thrall system was finally abolished in the mid-14th century in Scandinavia.

Mediterranean powers frequently sentenced convicted criminals to row in the war- galleys of the state (initially only in time of war). After the revocation of the Edict of Nantes in 1685 and Camisard rebellion, the French Crown filled its galleys with French Huguenots, Protestants condemned for resisting the state. Galley-slaves lived and worked in such harsh conditions that many did not survive their terms of sentence, even if they survived shipwreck and slaughter or torture at the hands of enemies or of pirates. Naval forces often turned 'infidel' prisoners-of-war into galley-slaves. Several well-known historical figures served time as galley slaves after being captured by the enemy-the Ottoman corsair and admiral Turgut Reis and the Knights Hospitaller Grand Master Jean Parisot de la Valette among them.

Denmark-Norway was the first European country to ban the slave trade. This happened with a decree issued by King Christian VII of Denmark in 1792, to become fully effective by 1803. Slavery as an institution was not banned until 1848. At this time Iceland was a part of Denmark-Norway but slave trading had been abolished in Iceland in 1117 and had never been reestablished.

Slavery in the French Republic was abolished on 4 February 1794, including in its colonies. The lengthy Haitian Revolution by its slaves and free people of color established Haiti as a free republic in 1804 ruled by blacks, the first of its kind. At the time of the revolution, Haiti was known as Saint-Domingue and was a colony of France. Napoleon Bonaparte gave up on Haiti in 1803, but re-established slavery in Guadeloupe and Martinique in 1804, at the request of planters of the Caribbean colonies. Slavery was permanently abolished in the French empire during the French Revolution of 1848.

The 15th-century Portuguese exploration of the African coast is commonly regarded as the harbinger of European colonialism. In 1452, Pope Nicholas V issued the papal bull Dum Diversas, granting Afonso V of Portugal the right to reduce any "Saracens, pagans and any other unbelievers" to hereditary slavery which legitimized slave trade under Catholic beliefs of that time. This approval of slavery was reaffirmed and extended in his Romanus Pontifex bull of 1455. These papal bulls came to serve as a justification for the subsequent era of the slave trade and European colonialism. Although for a short period as in 1462, Pius II declared slavery to be "a great crime". The followers of the church of England and Protestants did not use the papal bull as a justification. The position of the church was to condemn the slavery of Christians, but slavery was regarded as an old established and necessary institution which supplied Europe with the necessary workforce. In the 16th century, African slaves had replaced almost all other ethnicities and religious enslaved groups in Europe. Within the Portuguese territory of Brazil, and even beyond its original borders, the enslavement of Native Americans was carried out by the Bandeirantes.

Among many other European slave markets, Genoa, and Venice were some well-known markets, their importance and demand growing after the great plague of the 14th century which decimated much of the European workforce. The maritime town of Lagos, Portugal, was the first slave market created in Portugal for the sale of imported African slaves, the Mercado de Escravos, which opened in 1444. In 1441, the first slaves were brought to Portugal from northern Mauritania. Prince Henry the Navigator, major sponsor of the Portuguese African expeditions, as of any other merchandise, taxed one fifth of the selling price of the slaves imported to Portugal. By the year 1552 African slaves made up 10 percent of the population of Lisbon. In the second half of the 16th century, the Crown gave up the monopoly on slave trade and the focus of European trade in African slaves shifted from import to Europe to slave transports directly to tropical colonies in the Americas-in the case of Portugal, especially Brazil. In the 15th century, one-third of the slaves were resold to the African market in exchange of gold. Slavery was abolished in mainland Portugal and Portuguese India in 1761. It was finally abolished in all Portuguese colonies in 1869.

The Spaniards were the first Europeans to use African slaves in the New World on islands such as Cuba and Hispaniola, due to a shortage of labor caused by the spread of diseases, and so the Spanish colonists gradually became involved in the Atlantic slave trade. The first African slaves arrived in Hispaniola in 1501; by 1517, the natives had been "virtually annihilated" mostly to diseases. The problem of the justness of Native American's slavery was a key issue for the Spanish Crown. It was Charles V who gave a definite answer to this complicated and delicate matter. To that end, on 25 November 1542, the Emperor abolished slavery by decree in his Leyes Nuevas New Laws. This bill was based on the arguments given by the best Spanish theologists and jurists who were unanimous in the condemnation of such slavery as unjust; they declared it illegitimate and outlawed it from America-not just the slavery of Spaniards over Natives-but also the type of slavery practiced among the Natives themselves Thus, Spain became the first country to officially abolish slavery.

However, in the Spanish colonies of Cuba and Puerto Rico, where sugarcane production was highly profitable based on slave labor, African slavery persisted until 1873 in Puerto Rico "with provisions for periods of apprenticeship", and 1886 in Cuba.

Although slavery was illegal inside the Netherlands it flourished throughout the Dutch Empire in the Americas, Africa, Ceylon and Indonesia. The Dutch Slave Coast ( Dutch: Slavenkust) referred to the trading posts of the Dutch West India Company on the Slave Coast, which lie in contemporary Ghana, Benin, Togo and Nigeria. Initially the Dutch shipped slaves to northern Brazil, and during the second half of the 17th century they had a controlling interest in the trade to the Spanish colonies. Today's Suriname and Guyana became prominent markets in the 18th century. Between 1612 and 1872, the Dutch operated from some 10 fortresses along the Gold Coast (now Ghana), from which slaves were shipped across the Atlantic. Dutch involvement on the Slave Coast increased with the establishment of a trading post in Offra in 1660. Willem Bosman writes in his Nauwkeurige beschrijving van de Guinese Goud- Tand- en Slavekust (1703) that Allada was also called Grand Ardra, being the larger cousin of Little Ardra, also known as Offra. From 1660 onward, Dutch presence in Allada and especially Offra became more permanent. A report from this year asserts Dutch trading posts, apart from Allada and Offra, in Benin City, Grand-Popo, and Savi.

The Offra trading post soon became the most important Dutch office on the Slave Coast. According to a 1670 report, annually 2,500 to 3,000 slaves were transported from Offra to the Americas. These numbers were only feasible in times of peace, however, and dwindled in time of conflict. From 1688 onward, the struggle between the Aja king of Allada and the peoples on the coastal regions, impeded the supply of slaves. The Dutch West India Company chose the side of the Aja king, causing the Offra office to be destroyed by opposing forces in 1692. By 1650 the Dutch had the pre-eminent slave trade in Europe and South East Asia. Later, trade shifted to Ouidah. On the instigation of Governor-General of the Dutch Gold Coast Willem de la Palma, Jacob van den Broucke was sent in 1703 as "opperkommies" (head merchant) to the Dutch trading post at Ouidah, which according to sources was established around 1670. Political unrest caused the Dutch to abandon their trading post at Ouidah in 1725, and they then moved to Jaquim, at which place they built Fort Zeelandia. The head of the post, Hendrik Hertog, had a reputation for being a successful slave trader. In an attempt to extend his trading area, Hertog negotiated with local tribes and mingled in local political struggles. He sided with the wrong party, however, leading to a conflict with Director-General Jan Pranger and to his exile to the island of Appa in 1732. The Dutch trading post on this island was extended as the new centre of the slave trade. In 1733, Hertog returned to Jaquim, this time extending the trading post into Fort Zeelandia. The revival of the slave trade at Jaquim was only temporary, however, as his superiors at the Dutch West India Company noticed that Hertog's slaves were more expensive than at the Gold Coast. From 1735, Elmina became the preferred spot to trade slaves. As of 1778, it was estimated that the Dutch were shipping approximately 6,000 Africans for enslavement in the Dutch West Indies each year. Slavery also characterised the Dutch possessions in Indonesia, Ceylon and South Africa, where Indonesians have made a significant contribution to the Cape Coloured population of that country. The Dutch part in the Atlantic slave trade is estimated at 5-7 percent, as they shipped about 550,000-600,000 African slaves across the Atlantic, about 75,000 of whom died on board before reaching their destinations. From 1596 to 1829, the Dutch traders sold 250,000 slaves in the Dutch Guianas, 142,000 in the Dutch Caribbean islands, and 28,000 in Dutch Brazil. In addition, tens of thousands of slaves, mostly from India and some from Africa, were carried to the Dutch East Indies. The Netherlands was one of the last countries to abolish slavery in 1863. Although the decision was made in 1848, it took many years for the law to be implemented. Furthermore, slaves in Suriname would be fully free only in 1873, since the law stipulated that there was to be a mandatory 10-year transition.

Barbary Corsairs continued to trade in European slaves into the Modern time-period. Muslim pirates, primarily Algerians with the support of the Ottoman Empire, raided European coasts and shipping from the 16th to the 19th centuries, and took thousands of captives, whom they sold or enslaved. Many were held for ransom, and European communities raised funds such as Malta's Monte della Redenzione degli Schiavi to buy back their citizens. The raids gradually ended with the naval decline of the Ottoman Empire in the late 16th and 17th centuries, as well as the European conquest of North Africa throughout the 19th century.

From 1609 to 1616, England lost 466 merchant ships to Barbary pirates. 160 English ships were captured by Algerians between 1677 and 1680. Many of the captured sailors were made into slaves and held for ransom. The corsairs were no strangers to the South West of England where raids were known in a number of coastal communities. In 1627 Barbary Pirates under command of the Dutch renegade Jan Janszoon (Murat Reis), operating from the Moroccan port of Salé, occupied the island of Lundy. During this time there were reports of captured slaves being sent to Algiers.

Ireland, despite its northern position, was not immune from attacks by the corsairs. In June 1631 Janszoon, with pirates from Algiers and armed troops of the Ottoman Empire, stormed ashore at the little harbor village of Baltimore, County Cork. They captured almost all the villagers and took them away to a life of slavery in North Africa. The prisoners were destined for a variety of fates-some lived out their days chained to the oars as galley slaves, while others would spend long years in the scented seclusion of the harem or within the walls of the sultan's palace. Only two of them ever saw Ireland again.

The Congress of Vienna (1814-15), which ended the Napoleonic Wars, led to increased European consensus on the need to end Barbary raiding. The sacking of Palma on the island of Sardinia by a Tunisian squadron, which carried off 158 inhabitants, roused widespread indignation. Britain had by this time banned the slave trade and was seeking to induce other countries to do likewise. States that were more vulnerable to the corsairs complained that Britain cared more for ending the trade in African slaves than stopping the enslavement of Europeans and Americans by the Barbary States.

In order to neutralise this objection and further the anti-slavery campaign, in 1816 Britain sent Lord Exmouth to secure new concessions from Tripoli, Tunis, and Algiers, including a pledge to treat Christian captives in any future conflict as prisoners of war rather than slaves. He imposed peace between Algiers and the kingdoms of Sardinia and Sicily. On his first visit, Lord Exmouth negotiated satisfactory treaties and sailed for home. While he was negotiating, a number of Sardinian fishermen who had settled at Bona on the Tunisian coast were brutally treated without his knowledge. As Sardinians they were technically under British protection, and the government sent Exmouth back to secure reparation. On 17 August, in combination with a Dutch squadron under Admiral Van de Capellen, Exmouth bombarded Algiers. Both Algiers and Tunis made fresh concessions as a result.

The Barbary states had difficulty securing uniform compliance with a total prohibition of slave-raiding, as this had been traditionally of central importance to the North African economy. Slavers continued to take captives by preying on less well-protected peoples. Algiers subsequently renewed its slave-raiding, though on a smaller scale. Europeans at the Congress of Aix-la-Chapelle in 1818 discussed possible retaliation. In 1820 a British fleet under Admiral Sir Harry Neal bombarded Algiers. Corsair activity based in Algiers did not entirely cease until France conquered the state in 1830.

The Crimeans frequently mounted raids into the Danubian principalities, Poland-Lithuania, and Muscovy to enslave people whom they could capture; for each captive, the khan received a fixed share (savğa) of 10% or 20%. These campaigns by Crimean forces were either sefers ("sojourns" - officially declared military operations led by the khans themselves), or çapuls ("despoiling" - raids undertaken by groups of noblemen, sometimes illegally because they contravened treaties concluded by the khans with neighbouring rulers).

For a long time, until the early 18th century, the Crimean Khanate maintained a massive slave trade with the Ottoman Empire and the Middle East, exporting about 2 million slaves from Russia and Poland-Lithuania over the period 1500-1700. Caffa (modern Feodosia) became one of the best-known and significant trading ports and slave markets. In 1769 the last major Tatar raid saw the capture of 20,000 Russian and Ruthenian slaves.

Author and historian Brian Glyn Williams writes:

Fisher estimates that in the sixteenth century the Polish-Lithuanian Commonwealth lost around 20,000 individuals a year and that from 1474 to 1694, as many as a million Commonwealth citizens were carried off into Crimean slavery.

Early modern sources are full of descriptions of sufferings of Christian slaves captured by the Crimean Tatars in the course of their raids:

It seems that the position and everyday conditions of a slave depended largely on his/her owner. Some slaves indeed could spend the rest of their days doing exhausting labor: as the Crimean vizir (minister) Sefer Gazi Aga mentions in one of his letters, the slaves were often "a plough and a scythe" of their owners. Most terrible, perhaps, was the fate of those who became galley-slaves, whose sufferings were poeticized in many Ukrainian dumas (songs). ... Both female and male slaves were often used for sexual purposes.

Britain played a prominent role in the Atlantic slave trade, especially after 1640, when sugar cane was introduced to the region. At first, most were white Britons, or Irish, enslaved as indentured labour - for a fixed period - in the West Indies. These people may have been criminals, political rebels, the poor with no prospects or others who were simply tricked or kidnapped. Slavery was a legal institution in all of the 13 American colonies and Canada (acquired by Britain in 1763). The profits of the slave trade and of West Indian plantations amounted to 5% of the British economy at the time of the Industrial Revolution.

A little-known incident in the career of Judge Jeffreys refers to an assize in Bristol in 1685 when he made the mayor of the city, then sitting fully robed beside him on the bench, go into the dock and be fined £1000 for being a 'kidnapping knave'; some Bristol traders at the time were known at the time to kidnap their own countrymen and ship them away as slaves.

Somersett's case in 1772 was generally taken at the time to have decided that the condition of slavery did not exist under English law in England. In 1785, English poet William Cowper wrote: "We have no slaves at home - Then why abroad? Slaves cannot breathe in England; if their lungs receive our air, that moment they are free. They touch our country, and their shackles fall. That's noble, and bespeaks a nation proud. And jealous of the blessing. Spread it then, And let it circulate through every vein." However, slavery continued to thrive in England itself, much like it did in the British Empire, until full emancipation in the 1830s. In 1807, following many years of lobbying by the abolitionist movement, led primarily by William Wilberforce, the British Parliament voted to make the slave trade illegal anywhere in the Empire with the Slave Trade Act 1807. Thereafter Britain took a prominent role in combating the trade, and slavery itself was abolished in the British Empire (except for India) with the Slavery Abolition Act 1833. Between 1808 and 1860, the West Africa Squadron seized approximately 1,600 slave ships and freed 150,000 Africans who were aboard. Action was also taken against African leaders who refused to agree to British treaties to outlaw the trade. Akitoye, the 11th Oba of Lagos, is famous for having used British involvement to regain his rule in return for suppressing slavery among the Yoruba people of Lagos in 1851. Anti-slavery treaties were signed with over 50 African rulers. In 1839, the world's oldest international human rights organization, Anti-Slavery International, was formed in Britain by Joseph Sturge, which worked to outlaw slavery in other countries.

After 1833, the freed African slaves declined employment in the cane fields. This led to the importation of indentured labour again - mainly from India, and also China.

In 1811, Arthur William Hodge was executed for the murder of a slave in the British West Indies. He was not, however, as some have claimed, the first white person to have been lawfully executed for the murder of a slave.

During World War II Nazi Germany operated several categories of Arbeitslager (Labor Camps) for different categories of inmates. The largest number of them held Polish and Jewish civilians forcibly abducted in the occupied countries (see Łapanka) to provide labor in the German war industry, repair bombed railroads and bridges or work on farms. By 1944, 20% of all workers were foreigners, either civilians or prisoners of war.

This is not classed as slavery per se, as defined in the first paragraph, i.e. slavery under this definition does not include other forced labour systems, such as historical forced labor by prisoners, labor camps, or other forms of unfree labor, in which labourers are not legally considered property. Slavery typically requires a shortage of labor and a surplus of land to be viable.

As agreed by the Allies at the Yalta conference Germans were used as forced labor as part of the reparations to be extracted. By 1947 it is estimated that 400,000 Germans (both civilians and POWs) were being used as forced labor by the U.S., France, the UK and the Soviet Union. German prisoners were for example forced to clear minefields in France and the Low Countries. By December 1945 it was estimated by French authorities that 2,000 German prisoners were being killed or injured each month in accidents. In Norway the last available casualty record, from 29 August 1945, shows that by that time a total of 275 German soldiers died while clearing mines, while 392 had been injured. Death rates for the German civilians doing forced labor in the Soviet Union ranged between 19% and 39%, depending on category.

In the first half of the 19th century, small-scale slave raids took place across Polynesia to supply labor and sex workers for the whaling and sealing trades, with examples from both the westerly and easterly extremes of the Polynesian triangle. By the 1860s this had grown to a larger scale operation with Peruvian slave raids in the South Sea Islands to collect labor for the guano industry.

Ancient Hawaii was a caste society. People were born into specific social classes. Kauwa were those of the outcast or slave class. They are believed to have been war captives, or the descendants of war captives. Marriage between higher castes and the kauwa was strictly forbidden. The kauwa worked for the chiefs and were often used as human sacrifices at the luakini heiau. (They were not the only sacrifices; law-breakers of all castes or defeated political opponents were also acceptable as victims.)

The kapu system was abolished during the ʻAi Noa in 1819, and with it the distinction between the kauwā slave class and the makaʻāinana (commoners). The 1852 Constitution of the Kingdom of Hawaii officially made slavery illegal.

Before the arrival of European settlers, each Maori tribe () considered itself a separate entity equivalent to a nation. In traditional Maori society of Aotearoa, prisoners of war became taurekareka, slaves, unless released, ransomed or eaten. With some exceptions, the child of a slave remained a slave.

As far as it is possible to tell, slavery seems to have increased in the early 19th century with increased numbers of prisoners being taken by Māori military leaders, such as Hongi Hika and Te Rauparaha to satisfy the need for labor in the Musket Wars, to supply whalers and traders with food, flax and timber in return for western goods. The intertribal Musket Wars lasted 1807 to 1843 when large numbers of slaves were captured by northern tribes who had acquired muskets. About 20,000 Maori died in the wars which were concentrated in the North Island. An unknown number of slaves were captured. Northern tribes used slaves (called mokai) to grow large areas of potatoes for trade with visiting ships. Chiefs started an extensive sex trade in the Bay of Islands in the 1830s using mainly slave girls. By 1835 about 70-80 ships per year called into the port. One French captain described the impossibility of getting rid of the girls who swarmed over his ship outnumbering his crew of 70 by 3 to 1. All payments to the girls were stolen by the chief. By 1833 Christianity had become established in the north and large numbers of slaves were freed. However two Taranaki tribes, Ngati Tama and Ngati Mutunga, displaced by the wars carried out a carefully planned invasion of the Chatham Islands, 800 km east of Christchurch, in 1835. About 15% of the Polynesian Moriori natives who had migrated to the islands at about 1500 CE were killed, with many women being tortured to death. The remaining population was enslaved for the purpose of growing food, especially potatoes. The Moriori were treated in an inhumane and degrading manner for many years. Their culture was banned and they were forbidden to marry. Slavery was outlawed when the British entered into a constitutional arrangement with New Zealand in 1840 via the Treaty of Waitangi, although it did not end completely until government was effectively extended over the whole of the country with the defeat of the Kingi movement in the Wars of the mid-1860s.

Some Maori took Moriori partners. The state of enslavement of Moriori lasted until the 1860s although it had been discouraged by CMS missionaries in North New Zealand from the late 1820s. In 1870 Ngati Mutunga, one of the invading tribes, argued before the Native Land Court in New Zealand that their gross mistreatment of the Moriori was standard Maori practice or tikanga.

One group of Polynesians who migrated to the Chatham Islands became the Moriori who developed a largely pacifist culture. It was originally speculated that they settled the Chathams direct from Polynesia, but it is now widely believed they were disaffected Maori who emigrated from the South Island of New Zealand. Their pacifism left the Moriori unable to defend themselves when the islands were invaded by mainland Māori in the 1830s. Two Taranaki tribes, Ngati Tama and Ngati Mutunga, displaced by the musket wars, carried out a carefully planned invasion of the Chatham Islands, 800 km east of Christchurch, in 1835. About 15% of the Polynesian Moriori natives who had migrated to the islands at about 1500 CE were killed, with many women being tortured to death. The remaining population was enslaved for the purpose of growing food, especially potatoes. The Moriori were treated in an inhumane and degrading manner for many years. Their culture was banned and they were forbidden to marry. Slavery was outlawed when the British annexed New Zealand in 1840, immediately prior to the signing of the Treaty of Waitangi, although it did not end completely until government was effectively extended over the whole of the country with the defeat of the Kingi movement in the Wars of the mid-1860s.

Some 300 Moriori men, women and children were massacred and the remaining 1,200 to 1,300 survivors were enslaved.

Rapa Nui / Easter Island

The isolated island of Rapa Nui/ Easter Island was inhabited by the Rapanui, who suffered a series of slave raids from 1805 or earlier, culminating in a near genocidal experience in the 1860s. The 1805 raid was by American sealers and was one of a series that changed the attitude of the islanders to outside visitors, with reports in the 1820s and 1830s that all visitors received a hostile reception. In December 1862, Peruvian slave raiders took between 1,400 and 2,000 islanders back to Peru to work in the guano industry; this was about a third of the island's population and included much of the island's leadership, the last ariki-mau and possibly the last who could read Rongorongo. After intervention by the French ambassador in Lima, the last 15 survivors were returned to the island, but brought with them smallpox, which further devastated the island.

Slavery has existed, in one form or another, throughout the whole of human history. So, too, have movements to free large or distinct groups of slaves. However, abolitionism should be distinguished from efforts to help a particular group of slaves, or to restrict one practice, such as the slave trade.

Although there were numerous slave revolts in the Caribbean, the only successful uprising came in the French colony of Haiti in the 1790s, where the slaves rose up, killed the mulattoes and whites, and established the independent Republic of Haiti. Europe recoiled in horror.

Cyrus the Great, the founder of Persian Empire prohibited the systematic enslavement of conquered non-combatant population. Cyrus also freed slaves and allowed all deported peoples who were enslaved by preceding Assyrian and Babylonian kings, to return home. It is said that he freed up to 40,000 Jews and allowed them to return home. Cylinder of Cyrus the Great containing the Decree on the conquered non-combatant population.

In 1772, the Somersett Case (R. v. Knowles, ex parte Somersett) of the English Court of King's Bench ruled that it was unlawful for a slave to be forcibly taken abroad. The case has since been misrepresented as finding that slavery was unlawful in England (although not elsewhere in the British Empire). A similar case, that of Joseph Knight, took place in Scotland five years later and ruled slavery to be contrary to the law of Scotland.

Following the work of campaigners in the United Kingdom, such as William Wilberforce and Thomas Clarkson, the Act for the Abolition of the Slave Trade was passed by Parliament on 25 March 1807, coming into effect the following year. The act imposed a fine of £100 for every slave found aboard a British ship. The intention was to outlaw entirely the Atlantic slave trade within the whole British Empire.

The significance of the abolition of the British slave trade lay in the number of people hitherto sold and carried by British slave vessels. Britain shipped 2,532,300 Africans across the Atlantic, equalling 41% of the total transport of 6,132,900 individuals. This made the British empire the biggest slave-trade contributor in the world due to the magnitude of the empire, which made the abolition act all the more damaging to the global trade of slaves. Britain used its diplomatic influence to press other nations into treaties to ban their slave trade and to give the Royal Navy the right to interdict slave ships sailing under their national flag.

The Slavery Abolition Act, passed on 1 August 1833, outlawed slavery itself throughout the British Empire, with the exception of India. On 1 August 1834 slaves became indentured to their former owners in an apprenticeship system for six years. Full emancipation was granted ahead of schedule on 1 August 1838. Britain abolished slavery in both Hindu and Muslim India with the Indian Slavery Act, 1843.

Domestic slavery practised by the educated African coastal elites (as well as interior traditional rulers) in Sierra Leone was abolished in 1928. A study found practices of domestic slavery still widespread in rural areas in the 1970s.

There were slaves in mainland France (especially in trade ports such as Nantes or Bordeaux)., but the institution was never officially authorized there. The legal case of Jean Boucaux in 1739 clarified the unclear legal position of possible slaves in France, and was followed by laws that established registers for slaves in mainland France, who were limited to a three-year stay, for visits or learning a trade. Unregistered "slaves" in France were regarded as free. However, slavery was of vital importance in France's Caribbean possessions, especially Saint-Domingue.

In 1793, influenced by the French Declaration of the Rights of Man of August 1789 and alarmed as the massive slave revolt of August 1791 that had become the Haitian Revolution threatened to ally itself with the British, the French Revolutionary commissioners Sonthonax and Polverel declared general emancipation to reconcile them with France. In Paris, on 4 February 1794, Abbé Grégoire and the Convention ratified this action by officially abolishing slavery in all French territories outside mainland France, freeing all the slaves both for moral and security reasons.

Napoleon came to power in 1799 and soon had grandiose plans for the French sugar colonies; to achieve them he reintroduced slavery. Napoleon's major adventure into the Caribbean-sending 30,000 troops in 1802 to retake Saint Domingue (Haiti) from ex-slaves under Toussaint L'Ouverture who had revolted. Napoleon wanted to preserve France's financial benefits from the colony's sugar and coffee crops; he then planned to establish a major base at New Orleans. He therefore re-established slavery in Haiti and Guadeloupe, where it had been abolished after rebellions. Slaves and black freedmen fought the French for their freedom and independence. Revolutionary ideals played a central role in the fighting for it was the slaves and their allies who were fighting for the revolutionary ideals of freedom and equality, while the French troops under General Charles Leclerc fought to restore the order of the ancien régime. The goal of re-establishing slavery explicitly contradicted the ideals of the French Revolution. The French soldiers were unable to cope with the tropical diseases, and most died of yellow fever. Slavery was reimposed in Guadeloupe but not in Haiti, which became an independent black republic. Napoleon's vast colonial dreams for Egypt, India, the Caribbean, Louisiana, and even Australia were all doomed for lack of a fleet capable of matching Britain's Royal Navy. Realizing the fiasco Napoleon liquidated the Haiti project, brought home the survivors and sold off the huge Louisiana territory to the US in 1803.

In 1794 slavery was abolished in the French Empire. After seizing Lower Egypt in 1798, Napoleon Bonaparte issued a proclamation in Arabic, declaring all men to be free and equal. However, the French bought males as soldiers and females as concubines. Napoleon personally opposed the abolition and restored colonial slavery in 1802, a year after the capitulation of his troops in Egypt.

Victor Schœlcher and the 1848 abolition

The American Colonization Society, the primary vehicle for returning black Americans to greater freedom in Africa, established the colony of Liberia in 1821-23, on the premise that former American slaves would have greater freedom and equality there. The ACS assisted in the movement of thousands of African Americans to Liberia, with its founder Henry Clay stating; "unconquerable prejudice resulting from their color, they never could amalgamate with the free whites of this country. It was desirable, therefore, as it respected them, and the residue of the population of the country, to drain them off". Abraham Lincoln, an enthusiastic supporter of Clay, adopted his position on returning the blacks to their own land.

Slaves in the United States who escaped ownership would often make their way to Canada via the " Underground Railroad". The more famous of the African American abolitionists include former slaves Harriet Tubman, Sojourner Truth and Frederick Douglass. Many more people who opposed slavery and worked for abolition were northern whites, such as William Lloyd Garrison and John Brown. Slavery was legally abolished in 1865 by the Thirteenth Amendment to the United States Constitution.

While abolitionists agreed on the evils of slavery, there were differing opinions on what should happen after African Americans were freed. By the time of Emancipation, African-Americans were now native to the United States and did not want to leave. Most believed that their labor had made the land theirs as well as that of the whites.

The Declaration of the Powers, on the Abolition of the Slave Trade, of 8 February 1815 (Which also formed ACT, No. XV. of the Final Act of the Congress of Vienna of the same year) included in its first sentence the concept of the "principles of humanity and universal morality" as justification for ending a trade that was "odious in its continuance".

The 1926 Slavery Convention, an initiative of the League of Nations, was a turning point in banning global slavery. Article 4 of the Universal Declaration of Human Rights, adopted in 1948 by the UN General Assembly, explicitly banned slavery. The United Nations 1956 Supplementary Convention on the Abolition of Slavery was convened to outlaw and ban slavery worldwide, including child slavery. In December 1966, the UN General Assembly adopted the International Covenant on Civil and Political Rights, which was developed from the Universal Declaration of Human Rights. Article 4 of this international treaty bans slavery. The treaty came into force in March 1976 after it had been ratified by 35 nations.

As of November 2003, 104 nations had ratified the treaty. However, illegal forced labour involves millions of people in the 21st century, 43% for sexual exploitation and 32% for economic exploitation.

In May 2004, the 22 members of the Arab League adopted the Arab Charter on Human Rights, which incorporated the 1990 Cairo Declaration on Human Rights in Islam, which states:

Human beings are born free, and no one has the right to enslave, humiliate, oppress or exploit them, and there can be no subjugation but to God the Most-High.

-  Article 11, Cairo Declaration on Human Rights in Islam, 1990

Currently, the Anti-trafficking Coordination Team Initiative (ACT Team Initiative), a coordinated effort between the U.S. departments of justice, homeland security and labor, addresses human trafficking. The International Labour Organization estimates that there are 20.9 million victims of human trafficking globally, including 5.5 million children, of which 55% are women and girls.

The history of slavery originally was the history of the government's laws and policies toward slavery, and the political debates about it. Black history was promoted very largely at black colleges. The situation changed dramatically with the coming of the Civil Rights Movement of the 1950s. Attention shifted to the enslaved humans, the free blacks, and the struggles of the black community against adversity.

Peter Kolchin described the state of historiography in the early 20th century as follows:

During the first half of the twentieth century, a major component of this approach was often simply racism, manifest in the belief that blacks were, at best, imitative of whites. Thus Ulrich B. Phillips, the era's most celebrated and influential expert on slavery, combined a sophisticated portrait of the white planters' life and behavior with crude passing generalizations about the life and behavior of their black slaves.

Historians James Oliver Horton and Lois E. Horton described Phillips' mindset, methodology and influence:

His portrayal of blacks as passive, inferior people, whose African origins made them uncivilized, seemed to provide historical evidence for the theories of racial inferiority that supported racial segregation. Drawing evidence exclusively from plantation records, letters, southern newspapers, and other sources reflecting the slaveholder's point of view, Phillips depicted slave masters who provided for the welfare of their slaves and contended that true affection existed between master and slave.

Their account of the era rested, as one member of the Dunning school put it, on the assumption of "negro incapacity." Finding it impossible to believe that blacks could ever be independent actors on the stage of history, with their own aspirations and motivations, Dunning et al. portrayed African Americans either as "children", ignorant dupes manipulated by unscrupulous whites, or as savages, their primal passions unleashed by the end of slavery.

In the portrayal of the slave as a victim, the historian Stanley M. Elkins in his 1959 work Slavery: A Problem in American Institutional and Intellectual Life compared the effects of United States slavery to that resulting from the brutality of the Nazi concentration camps. He stated the institution destroyed the will of the slave, creating an "emasculated, docile Sambo" who identified totally with the owner. Elkins' thesis was challenged by historians. Gradually historians recognized that in addition to the effects of the owner-slave relationship, slaves did not live in a "totally closed environment but rather in one that permitted the emergence of enormous variety and allowed slaves to pursue important relationships with persons other than their master, including those to be found in their families, churches and communities."

Economic historians Robert W. Fogel and Stanley L. Engerman in the 1970s, through their work Time on the Cross, portrayed slaves as having internalized the Protestant work ethic of their owners. In portraying the more benign version of slavery, they also argue in their 1974 book that the material conditions under which the slaves lived and worked compared favorably to those of free workers in the agriculture and industry of the time. (This was also an argument of Southerners during the 19th century.)

In the 1970s and 1980s, historians made use of sources such as black music and statistical census data to create a more detailed and nuanced picture of slave life. Relying also on 19th-century autobiographies of ex-slaves (known as slave narratives) and the WPA Slave Narrative Collection, a set of interviews conducted with former slaves in the 1930s by the Federal Writers' Project, historians described slavery as the slaves remembered it. Far from slaves' being strictly victims or content, historians showed slaves as both resilient and autonomous in many of their activities. Despite their exercise of autonomy and their efforts to make a life within slavery, current historians recognize the precariousness of the slave's situation. Slave children quickly learned that they were subject to the direction of both their parents and their owners. They saw their parents disciplined just as they came to realize that they also could be physically or verbally abused by their owners. Historians writing during this era include John Blassingame ( Slave Community), Eugene Genovese ( Roll, Jordan, Roll), Leslie Howard Owens ( This Species of Property), and Herbert Gutman ( The Black Family in Slavery and Freedom).

Important work on slavery has continued; for instance, in 2003 Steven Hahn published the Pulitzer Prize-winning account, A Nation under Our Feet: Black Political Struggles in the Rural South from Slavery to the Great Migration, which examined how slaves built community and political understanding while enslaved, so they quickly began to form new associations and institutions when emancipated, including black churches separate from white control. In 2010, Robert E. Wright published a model that explains why slavery was more prevalent in some areas than others (e.g. southern than northern Delaware) and why some firms (individuals, corporations, plantation owners) chose slave labor while others used wage, indentured, or family labor instead.

Historical revisionism arrived when West Indian historian Eric Williams, a Marxist, in Capitalism and Slavery (1944), rejected this moral explanation and argued that abolition was now more profitable, for a century of sugarcane raising had exhausted the soil of the islands, and the plantations had become unprofitable. It was more profitable to sell the slaves to the government than to keep up operations. The 1807 prohibition of the international trade, Williams argued, prevented French expansion on other islands. Meanwhile, British investors turned to Asia, where labor was so plentiful that slavery was unnecessary. Williams went on to argue that slavery played a major role in making Britain prosperous. The high profits from the slave trade, he said, helped finance the Industrial Revolution. Britain enjoyed prosperity because of the capital gained from the unpaid work of slaves.

Since the 1970s numerous historians have challenged Williams from various angles and Gad Heuman has concluded, "More recent research has rejected this conclusion; it is now clear that the colonies of the British Caribbean profited considerably during the Revolutionary and Napoleonic Wars." In his major attack on the Williams's thesis, Seymour Drescher argues that Britain's abolition of the slave trade in 1807 resulted not from the diminishing value of slavery for Britain but instead from the moral outrage of the British voting public. Critics have also argued that slavery remained profitable in the 1830s because of innovations in agriculture so the profit motive was not central to abolition. Richardson (1998) finds Williams's claims regarding the Industrial Revolution are exaggerated, for profits from the slave trade amounted to less than 1% of domestic investment in Britain. Richardson further challenges claims (by African scholars) that the slave trade caused widespread depopulation and economic distress in Africa-indeed that it caused the "underdevelopment" of Africa. Admitting the horrible suffering of slaves, he notes that many Africans benefited directly because the first stage of the trade was always firmly in the hands of Africans. European slave ships waited at ports to purchase cargoes of people who were captured in the hinterland by African dealers and tribal leaders. Richardson finds that the "terms of trade" (how much the ship owners paid for the slave cargo) moved heavily in favor of the Africans after about 1750. That is, indigenous elites inside West and Central Africa made large and growing profits from slavery, thus increasing their wealth and power.

Economic historian Stanley Engerman finds that even without subtracting the associated costs of the slave trade (e.g., shipping costs, slave mortality, mortality of British people in Africa, defense costs) or reinvestment of profits back into the slave trade, the total profits from the slave trade and of West Indian plantations amounted to less than 5% of the British economy during any year of the Industrial Revolution. Engerman's 5% figure gives as much as possible in terms of benefit of the doubt to the Williams argument, not solely because it does not take into account the associated costs of the slave trade to Britain, but also because it carries the full-employment assumption from economics and holds the gross value of slave trade profits as a direct contribution to Britain's national income. Historian Richard Pares, in an article written before Williams's book, dismisses the influence of wealth generated from the West Indian plantations upon the financing of the Industrial Revolution, stating that whatever substantial flow of investment from West Indian profits into industry there was occurred after emancipation, not before.

# data[].attributes.attachment_link.description
The history of slavery spans many cultures, nationalities, and religions from ancient times to the present day. However the social, economic, and legal positions of slaves have differed vastly in different systems of slavery in different times and places. Slavery occurs relatively rarely among hunter-gatherer populations because it develops under conditions of social stratification.
