The Neolithic Revolution started around 10,000 B.C. in the Fertile Crescent, a boomerang-shaped region of the Middle East where humans first took up farming. Shortly after, Stone Age humans in other parts of the world also began to practice agriculture. Civilizations and cities grew out of the innovations of the Neolithic Revolution.

Battle of Thermopylae, (480 BCE), battle in central Greece at the mountain pass of Thermopylae during the Persian Wars. The Greek forces, mostly Spartan, were led by Leonidas. After three days of holding their own against the Persian king Xerxes I and his vast southward-advancing army, the Greeks were betrayed, and the Persians were able to outflank them. Sending the main army in retreat, Leonidas and a small contingent remained behind to resist the advance and were defeated.

The start of Islam is marked in the year 610, following the first revelation to the prophet Muhammad at the age of 40. Muhammad and his followers spread the teachings of Islam throughout the Arabian peninsula. Soon after the death of the prophet Muhammad, there were military expeditions, called "futuhat," or literally "openings," into what is now Egypt and other parts of North Africa. In other parts of the world, Islam spread through trade and commerce. According to Muslim belief, at the age of 40, Muhammad is visited by the angel Gabriel while on retreat in a cave near Mecca. The angel recites to him the first revelations of the Quran and informs him that he is God's prophet. Later, Muhammad is told to call his people to the worship of the one God, but they react with hostility and begin to persecute him and his followers.

“Gunpowder,” as it came to be known, is a mixture of saltpeter (potassium nitrate), sulfur, and charcoal. Together, these materials will burn rapidly and explode as a propellant.

Chinese monks discovered the technology in the 9th century CE, during their quest for a life-extending elixir. The key ingredient, saltpeter, had been in use by this same culture since the late centuries BCE for medicinal purposes.The Mongols soon emerged as an ambitious and violent society, and their conquests and invasions acted as a vehicle by which gunpowder would spread to the rest of the world. It is documented that the technology had reached the Middle East by the 13th century CE, at which point traders as well as crusaders would have come into contact with it.

August 15, 1096. Those armies that left before that time are considered part of the People's Crusade. Three of these armies never made it past Hungary; two others (under Peter the Hermit and Walter Sansavoir) were defeated by Kilij Arslan of Nicaea.

Traditionally, the First Crusade deals with those who left after that official start date. As with the People's Crusade, these crusaders did not form one unified army. Though he required oaths of fealty and the return of any formerly Byzantine lands, Alexius refused leadership of the Crusade and did not take an active role; Stephen of Blois was the leader for a short time until he deserted; Adhémar of Le Puy was able to coordinate the different factions until his death in 1098.

The crusaders first gathered in Constantinople in fall 1096. They besieged Nicaea while Kilij Arslan was away (the city surrendered to Alexius), and later defeated an army commanded by Kilij Arslan at The Christian armies defended their conquest in August 1099 by defeating an Egyptian relief army. Pope Urban II died on July 29, 1099, without hearing the news.

The Inquisition was a powerful office set up within the Catholic Church to root out and punish heresy throughout Europe and the Americas. Beginning in the 12th century and continuing for hundreds of years, the Inquisition is infamous for the severity of its tortures and its persecution of Jews and Muslims. Its worst manifestation was in Spain, where the Spanish Inquisition was a dominant force for more than 200 years, resulting in some 32,000 executions.

Christopher Columbus did not “discover” the Americas, nor was he even the first European to visit the “New World.” (Viking explorer Leif Erikson had sailed to Greenland and Newfoundland in the 11th century.)

However, his journey kicked off centuries of exploration and exploitation on the American continents. The Columbian Exchange transferred people, animals, food and disease across cultures. Old World wheat became an American food staple. African coffee and Asian sugar cane became cash crops for Latin America, while American foods like corn, tomatoes and potatoes were introduced into European diets.

Green revolution, great increase in production of food grains (especially wheat and rice) that resulted in large part from the introduction into developing countries of new, high-yielding varieties, beginning in the mid-20th century. Its early dramatic successes were in Mexico and the Indian subcontinent. The new varieties require large amounts of chemical fertilizers and pesticides to produce their high yields, raising concerns about cost and potentially harmful environmental effects.

The Battle of the Somme, which took place from July to November 1916, began as an Allied offensive against German forces along the Western Front of World War I, near the Somme River in France. The battle turned into one of the most bitter, deadly and costly battles in all of human history, as British forces suffered more than 57,000 casualties—including more than 19,000 soldiers killed—on the first day of the battle alone. By the time the Battle of the Somme (sometimes called the First Battle of the Somme) ended nearly five months later, more than 3 million soldiers on both sides had fought in the battle, and more than 1 million had been killed or wounded.

The Treaty of Versailles was signed by Germany and the Allied Nations on June 28, 1919, formally ending World War One. The terms of the treaty required that Germany pay financial reparations, disarm, lose territory, and give up all of its overseas colonies. It also called for the creation of the League of Nations, an institution that President Woodrow Wilson strongly supported and had originally outlined in his Fourteen Points address. Despite Wilson's efforts, including a nationwide speaker tour, the Treaty of Versailles was rejected by the United States Senate twice, in 1919 and 1920. The United States ultimately signed a separate peace treaty with Germany in 1921, although it never joined the League of Nations.

The Holocaust was the state-sponsored persecution and mass murder of millions of European Jews, Romani people, the intellectually disabled, political dissidents and homosexuals by the German Nazi regime between 1933 and 1945. The word “holocaust,” from the Greek words “holos” (whole) and “kaustos” (burned), was historically used to describe a sacrificial offering burned on an altar.

After years of Nazi rule in Germany, dictator Adolf Hitler’s “Final Solution”—now known as the Holocaust—came to fruition during World War II, with mass killing centers in concentration camps. About six million Jews and some five million others, targeted for racial, political, ideological and behavioral reasons, died in the Holocaust—more than one million of those who perished were children.

The D-Day operation of June 6, 1944, brought together the land, air, and sea forces of the allied armies in what became known as the largest amphibious invasion in military history. The operation, given the codename OVERLORD, delivered five naval assault divisions to the beaches of Normandy, France. The beaches were given the code names UTAH, OMAHA, GOLD, JUNO, and SWORD. The invasion force included 7,000 ships and landing craft manned by over 195,000 naval personnel from eight allied countries. Almost 133,000 troops from the United States, the British Commonwealth, and their allies, landed on D-Day. Casualties from these countries during the landing numbered 10,300. By June 30, over 850,000 men, 148,000 vehicles, and 570,000 tons of supplies had landed on the Normandy shores.

Apartheid, the Afrikaans name given by the white-ruled South Africa's Nationalist Party in 1948 to the country's harsh, institutionalized system of racial segregation, came to an end in the early 1990s in a series of steps that led to the formation of a democratic government in 1994. Years of violent internal protest, weakening white commitment, international economic and cultural sanctions, economic struggles, and the end of the Cold War brought down white minority rule in Pretoria. U.S. policy toward the regime underwent a gradual but complete transformation that played an important conflicting role in Apartheid's initial survival and eventual downfall. The formal end of the apartheid government in South Africa was hard-won. It took decades of activism from both inside and outside the country, as well as international economic pressure, to end the regime that allowed the country’s white minority to subjugate its Black majority. This work culminated in the dismantling of apartheid between 1990 and 1994. On April 27, 1994, the country elected Nelson Mandela, an activist. who had spent 27 years in prison for his opposition to apartheid, in its first free presidential election.

of Muslims and Croats from their homes and summarily executed thousands. Bosnian
Croats and Muslims fought each other early on, but in 1994 they formed a federation to
counter the Serbs. The conflict ended in 1995 when all parties agreed to the Dayton
Peace Agreement, brokered by the United States. The agreement created two separate
entities within a greater Bosnia – the Republika Srpska and the Federation of Bosnia and
Hercegovina. The International Criminal Tribunal for the former Yugoslavia (ICTY) was

Somewhere in 2018-Cambridge Analytica goes bankrupt

# data[].attributes.body
Cambridge Analytica, the embattled data firm that worked on Donald Trump’s 2016 presidential campaign, announced it is shutting down operations.

“The Company is immediately ceasing all operations,” it said in a statement Wednesday, announcing bankruptcy proceedings would soon begin.

The filings note an estimated number of creditors between 1-49, estimated assets of $100,001 – $500,000 and estimated liabilities of $1,000,001 - $10 million. The company has come under fire over allegations it misused the personal Facebook data of millions.

The company has likewise struggled with the fallout of undercover recordings by Channel 4 News in the UK that showed executives at the firm discussing Cambridge Analytica’s efforts on behalf of the Trump campaign and the lengths to which they said they would be willing to go for prospective clients, including then-CEO Alexander Nix suggesting they would “send some girls around” in order to obtain compromising material on a hypothetical candidate.In its statement on Wednesday, the company stood by its actions, saying it maintains “unwavering confidence that its employees have acted ethically and lawfully,” but that “the siege of media coverage” had driven away its customers and suppliers. “As a result, it has been determined that it is no longer viable to continue operating the business, which left Cambridge Analytica with no realistic alternative to placing the Company into administration.
