# data[].attributes.attachment_link.description
The Battle of Gettysburg, fought over three hot summer days, from July 1 to July 3, 1863, is considered the most important engagement of the American Civil War. The South lost the battle—and many men—and it marked a turning point in the bloody war that left the South mostly on the defensive.

California Gold Rush, rapid influx of fortune seekers in California that began after gold was found at Sutter's Mill in early 1848 and reached its peak in 1852. According to estimates, more than 300,000 people came to the territory during the Gold Rush.

In 1848 John Sutter was having a water-powered sawmill built along the American River in Coloma, California, approximately 50 miles (80 km) east of present-day Sacramento. On January 24 his carpenter, James W. Marshall, found flakes of gold in a streambed. Sutter and Marshall agreed to become partners and tried to keep their find a secret. News of the discovery, however, soon spread, and they were besieged by thousands of fortune seekers. (With his property overrun and his goods and livestock stolen or destroyed, Sutter was bankrupt by 1852.) From the East, prospectors sailed around Cape Horn or risked disease hiking across the Isthmus of Panama. The hardiest took the 2,000-mile (3,220-km) overland route, on which cholera proved a far greater killer than the Native Americans. By August 1848, 4,000 gold miners were in the area, and within a year about 80,000 "forty-niners" (as the fortune seekers of 1849 were called) had arrived at the California goldfields. By 1853 their numbers had grown to 250,000. Although it was estimated that some $2 billion in gold was extracted, few of the prospectors struck it rich. The work was hard, prices were high, and living conditions were primitive.

In what was a typical pattern, the Gold Rush slackened as the most-workable deposits were exhausted and organized capital and machinery replaced the efforts of individual miner-adventurers with more efficient and businesslike operations. Likewise, the lawless and violent mining camps gave way to permanent settlements with organized government and law enforcement. Those settlements that lacked other viable economic activities soon became ghost towns after the gold was exhausted. The California Gold Rush peaked in 1852, and by the end of the decade, it was over.

The Gold Rush had a profound impact on California, dramatically changing its demographics. Before the discovery of gold, the territory's population was approximately 160,000, the vast majority of whom were Native Americans. By about 1855, more than 300,000 people had arrived. Most were Americans, though a number of settlers also came from China, Europe, and South America. The massive influx gave rise to numerous cities and towns, with San Francisco gaining particular prominence. The Gold Rush was credited with hastening statehood for California in 1850.

"If a Western Rip Van Winkle had fallen asleep in 1869 and awakened in 1896, he would not have recognized the lands that the railroads had touched. Bison had yielded to cattle; mountains had been blasted and bored. Great swaths of land that had once whispered grass now screamed corn and wheat. Nation-states had conquered Indian peoples, slaughtering some of them and confining and controlling most of them. Population had increased across much of this vast region, and there were growing cities along its edges. A land that had once run largely north-south now ran east-west. Each change could have been traced back to the railroads." - Richard White, Railroaded

Unprecedented Urbanization

Between 1820 and 1860, the visual map of the United States was transformed by unprecedented urbanization and rapid territorial expansion. These changes mutually fueled the Second Industrial Revolution which peaked between 1870 and 1914. Between the annexation of Texas (1845), the British retreat from Oregon country, and The Treaty of Guadalupe-Hidalgo (1848) which cemented Mexican cession of the Southwest to the United States, territorial expansion exponentially rewrote the competing visions free-soilers, European immigrants, industrial capitalists, and Native Americans held for the future of the American Empire.

Need for Railroads

The need for massive industry was obvious: in order to reach California's burgeoning port cities like San Francisco and to expedite the extraction of gold from the mines, railroad tracks would need to be laid across the plains to reach the Pacific and open up trade networks. Questions abounded about the character this new American territory would take: would it be reliant on slave labor and fulfill Jefferson's original vision of an agrarian republic? Would corporations or the federal government lay down the required infrastructure to 'tame the West'? Still, others wondered if turning over the bison laden Plains to New York based corporations would stifle the American dream for America's second and third sons. Still, others believed the technological innovations of the Second Industrial Revolution was the unstoppable culmination of modern civilization propelling the fulfillment of Manifest Destiny. Questions of this nature were not new in American history. Throughout the first half of the nineteenth century, Americans were forced to adjust to the implications of the First Industrial Revolution. 1750 to 1850 marked a century of heightened industrial activity centered around textiles. After the invention of steam power and the cotton gin by Eli Whitney in 1793, cotton could be shipped from the American South by New England ships to the vast textile factories of Great Britain, producing a reverse triangle trade around a single global commodity. These developments were hailed by some as "progress," but the pace, scale, and reliance of slave labor on these developments instilled in others a great sense of anxiety and fear.

Although the economic and social problems of the first Industrial Revolution distressed many, these concerns were set aside during the nation's bloody Civil War (1861-1865).

The following maps demonstrate the advancement of the railroad before the Civil War (as always, click to enlarge image):

American Economic Growth

In the aftermath of the Civil War and Reconstruction, the American economy grew considerably as it entered "The Second Industrial Revolution," generally recognized as the period between 1870 and 1914. The U.S. was awash in an abundance of natural resources from its newly acquired territories, a growing supply of labor immigrating from Europe, and the migration of emancipated African Americans North and West, an expanding market for manufactured goods, and the availability of capital for investment.

The Second Industrial Revolution took local communities and their new products out of the shadow of large regional agricultural based economies which was assisted by new labor forces and production techniques. During the Second Industrial Revolution, innovations in transportation, such as roads, steamboats, the Eerie Canal, and most notably railroads, linked distant, previously isolated communities together.

Transporting Products

For the first time, goods from the American interior could be shipped directly to the Atlantic, and vice versa. Being able to ship products great distances transformed the nature of economic activity in the United States. Before the development of this elaborate transportation and communication system, economies were localized and often based on a barter system. The transportation revolution opened up new markets for farmers, industrialists, and bankers who could now bring crops cotton in the Mississippi River Valley, wheat in the Midwest, and manufactured goods in upstate New York into a global market based on credit. Similarly, the expansion of the railroad brought a dramatic reduction in the time and money it took to move heavy goods, creating new opportunities for wealth at a time when two-thirds of all Americans still resided on farms.

Government Involvement

The federal government actively participated in this growth by promoting industrial and agricultural development. High tariffs were enacted to protect American industry from foreign competition, land was granted to railroad companies to encourage construction, and the army was employed to forcibly remove Indians from western land desired by farmers and mining companies. The rapid growth of factory production, mining, and railroad construction all boosted the new industrial economy and stood in stark contrast to the previous small farm and artisan workshop economy of the pre-Civil War era.

By 1913, the United States produced one-third of the world's industrial out put-more than the total of Great Britain, France, and Germany combined. The living standards and the purchasing power of money increased rapidly, as new technologies played an ever-increasing role in the daily lives of working- and middle-class citizens. Between 1870 and 1920, almost 11 million Americans moved from farm to city, and another 25 million immigrants arrived from overseas. By 1920, for the first time in American history, the census revealed more people lived in cities than on farms.

Interconnected Growth

Inventions during the Second Industrial Revolution were interconnected. The railroad spurred the growth of the telegraph machine. Telegraph lines and railroad lines inextricably bound together as telegraph polls dotted the distance of railroad lines. The telegraph, and later the telephone, ushered in the era of instant communication and brought about, in the words of cultural historian Stephen Kern, "the annihilation of distance." This was a profound change for Americans. The "local" shot outward to the "national" and even "international" as a new sense of world unity was established through these new technologies. These technologies also increased the pace of life and the manner in which people worked and lived.

Major Technological Advances of the Second Industrial Revolution:

* 1870s - Automatic signals, air brakes, and knuckle couplers on the railroads; the Bessemer and then the open-hearth process in the steel mills; the telephone, electric light, and typewriter.
* 1880s - The elevator and structural steel for buildings, leading to the first "skyscrapers."
* 1890s - The phonograph and motion pictures; the electric generator, contributing to modern household items such as refrigerators and washing machines and gradually replaced water and steam powered engines; and the internal combustion engine, which made possible the first automobiles and the first airplane flight by the Wright brothers in 1903.

Unstable Growth

The economic growth during this time period was extraordinary but unstable. The world economy experienced harsh depressions in 1873 and again in 1897. Businesses competed intensely with each other and corporations battled to gain control of industries. Countless companies failed and others were bought up by larger corporations which eventually ruled the marketplace.

For those who were able to capitalize on these technological advancements, the Second Industrial Revolution was highly profitable. During the Depression of 1873, the soon-to-be industry giant, Andrew Carnegie established a steel company which controlled every phase of business from raw materials to transportation, manufacturing, and distribution.

Carnegie Fortune

By the 1890s, Carnegie dominated the steel industry and had accumulated a fortune worth millions. His steel factories were the most technologically advanced in the world, although this honor came at a price for his workers. Carnegie ran his companies with a dictatorial hand; his factories operated around the clock and workers were burdened with long hours. Yet, at the same time, Carnegie believed that the rich had a moral obligation to promote the advancement of society and he distributed much of his wealth to various philanthropies, especially towards the creation of public libraries throughout the country.

Like Carnegie, John D. Rockefeller also accumulated enormous amounts of wealth, although his came through domination of the oil industry.

Beating the Competition

Rockefeller annihilated rival oil firms through committed competition, secret deals with railroad companies, and fixed prices and production quotas. He bought out competing oil refineries and managed all aspects of the operation, including drilling, refining, storage, and distribution. Before long, Rockefeller's Standard Oil Company controlled a majority of the nation's oil industry. Like Carnegie, Rockefeller publicly supported a number of philanthropies, yet privately domineered over his workers and bitterly fought their efforts to organize and unionize.

The Second Industrial Revolution fueled the Gilded Age, a period of great extremes: great wealth and widespread poverty, great expansion and deep depression, new opportunities and greater standardization. Economic insecurity became a basic way of life as the depressions of the 1870s and 1890s put millions out of work or reduced pay. Those who remained in the industrial line of work experienced extremely dangerous working conditions, long hours, no compensation for injuries, no pensions, and low wages. But for a limited minority of workers, the industrial system established new forms of freedom. Skilled workers received high wages in industrial work and oversaw a great deal of the production process. Economic independence now required a technical skill rather than ownership of one's own shop and tools. It was labeled "progress" by its proponents, but those who worked the floor at the factory knew it came at a price.

Science Lesson: Learn About Inventions

The Telephone & Alexander Graham Bell

What if the only way you could communicate with someone living in another city was by mailing them a letter, one that might take weeks to get delivered? (Even with our modern technology, it still takes at least two weeks for mail to get to some countries.) The telephone is certainly one of the greatest inventions in the history of communication!

The inventor of the telephone, Alexander Graham Bell, was born in Scotland in 1847, the same year as Thomas Edison. He went to university in Edinburgh and London, then immigrated to Canada in 1870 and to the U.S. a year later. There he used visible speech (a type of phonetic notation that shows the position of the throat, mouth, and tongue to make different sounds) to teach deaf-mute people how speak.

When he was a young man, Bell became interested in transmitting speech, the way a telegraph transmitted messages. In 1874 he developed the idea for the telephone and successfully created and patented one two years later. (Just two hours after he applied for his patent, Elisha Gray filed his intention to apply for a patent for a very similar device.) His first transmitted sentence was to his assistant: 'Watson, come here; I want to see you.' Bell demonstrated his telephone at the Philadelphia Centennial Expo and in 1877 organized the Bell Telephone Company.

So how does this amazing invention work? How can you talk to someone miles away and hear them as though they were in the same room with you? It's actually a fairly simple process. At its most basic, a telephone consists of a switch, a receiver, and a microphone. The switch connects your phone to the telephone network; the receiver changes electrical signals into sound waves so you can hear the other person, and the microphone changes the sound waves you make into electrical impulses to send to the other end of the line.

The microphone contains carbon granules and a thin metal diaphragm. When you speak, the sound waves (vibrations in the air) hit the diaphragm and cause it to move, compressing the carbon granules behind it. A louder sound will compress the granules more than a soft sound. When the carbon is compressed, an electrical current can flow through it more easily. A battery (either in your handset or at the telephone company) sends an electric current through your phone; when you speak, the compression of the carbon varies the intensity of the current.
Experiment with electricity and sound transmission with this kit for kids!
This process is reversed at the other end of the line by the receiver. The electrical current flows through an electromagnet in the receiver, producing a magnetic field. This magnetic field attracts the thin metal diaphragm in the receiver, causing it to move in and out. As it does so, it pushes and pulls the air, creating sound waves. These waves reach your ear with the same intensity as they were spoken, allowing you to hear what the other person said.

The process hinges on the ability to have a variable electrical current. Unlike the telephone, a telegraph operates on a constant electric current - the messages are transmitted not by changing the current, but by repeatedly turning it on and off in a distinct pattern. Because the human voice doesn't start and stop sound waves in the same way as tapping Morse code does, the current must be able to adjust for variation in volume and frequency. The carbon microphone allows for this variation, giving us the ability to transmit speech electrically.

Bell probably couldn't have imagined the kind of communication we have today. Not only do we have long-distance telephone networks all over the world, we also have cellular phones that use radio frequencies to allow us to talk wirelessly wherever we are. Communication was changed forever by the telephone and continues to develop rapidly today.

The Light Bulb & Thomas Edison

Perhaps one of the most important inventions of all time is the electric light bulb. We could get by with candles or lanterns in our homes, but imagine trying to shop at the mall, work in a large office complex, or travel at night by car or plane without electric lighting!

Thomas Alva Edison, one of the developers of the modern light bulb, is also one of the most famous as well as prolific inventors in history. He patented over 1000 inventions in his lifetime. Edison was born in Ohio in 1847. As a child, he received less than a year of formal schooling, but was educated at home. His parents allowed him to set up a laboratory in their basement and his mother gave him books about chemistry and electronics. Edison credits his mother as being 'the making' of him.

When he was 12, Edison got a job selling newspapers on a train that made day trips between his hometown of Port Huron, Michigan and Detroit. He took his laboratory along in the baggage car so that he would be able to experiment during layovers. This worked until one day some of his chemicals spilled and started a fire! Also while working on the train, Edison saved the child of one of the station masters, and as a reward was taught how to use a telegraph machine. He became a telegraph operator and began making improvements to the telegraph's functionality. He later invented a way for multiple telegraph messages to be transmitted simultaneously (rather than one at a time).

As a young man, Edison moved to New York City and eventually established a laboratory. In 1877 he invented the phonograph, which used a record made of tinfoil to play back sound. In 1879 he created a successful incandescent light bulb. This was his hardest project - from 1877 to 1880, Edison and his assistants tried around 3000 experiments to perfect their light bulb design. By the end of 1880, Edison had produced a bulb that lasted 1500 hours. (This has a moral: don't worry if some of your own science experiments aren't a success the first time you try them!)
Experiment with electricity with our student-friendly kit!
Edison was not the first person to make a working light bulb: In the 1860s another English scientist, Sir Joseph Wilson Swan, began experimenting. He made a light bulb that used carbonized paper for a filament. But Swan lacked a strong enough vacuum inside the bulb; a design problem that he corrected at almost the same time Edison did. After a legal battle between the two inventors, Edison and Swan teamed up and created the company Ediswan to market their invention.

How exactly do light bulbs work? For being such an important part of our lives, they have a fairly simple design. The base contains two metal contacts, which connect to an electrical circuit. These contacts are attached to two wires, which are in turn attached to the filament in the middle of the bulb (the filament is usually supported by a glass mount). A power supply sends an electric current from one contact to the other, traveling up through the wires and the filament. As the current passes through the filament, it "excites" the atoms that make up the filament material, causing them to give off energy in the form of heat and light. Edison tried thousands of different materials for his filaments, but most of them produced light for only a short time. He finally tried a carbonized cotton thread, which burned for many hours. Eventually, light bulbs were made using the metal tungsten for the filament. Tungsten works well because it has an unusually high melting point. This is important because metal must be heated to extreme temperatures to give off enough light.

The danger of running electrical current through the filament is that the resulting high temperatures may cause the filament to combust, or catch on fire. This will only happen if oxygen is present, so Edison sucked all the air out of his glass bulbs to create a vacuum. This method worked fine to prevent combustion, but it allowed filament atoms to evaporate, shortening the life of the bulb. In modern bulbs, the glass is filled with an inert gas, such as argon. This prevents combustion, and also helps prevent tungsten atoms from evaporating.

For over a century we have read and worked by the light of Edison's incandescent bulb. Other light sources, such as fluorescent bulbs and LED, have gained popularity in recent years because of their efficiency. The incandescent bulb releases most of its energy in the form of heat, not light, thus wasting electricity. Fluorescent and LED, however, are much cooler, and release most of their energy as visible light. These light sources have replaced the incandescent bulb for many functions.

Although almost all of Edison's discoveries were technological rather than strictly scientific, his invention credits include an alkaline storage battery, microphone, mimeograph (a copy machine), and a kinetoscope for viewing moving pictures. He also created the first 'talkie,' a movie that had sound, using his kinetoscope and phonograph. He continued to improve not only the incandescent light bulb, but some of his other inventions like the phonograph as well.

The Airplane and the Wright Brothers

On December 17, 1903, Orville Wright flew the first powered, heavier-than-air airplane, propelling himself and his older brother Wilbur into world history. It took the brothers years of preparation to get to that cold and windy day in Kitty Hawk, North Carolina.

Wilbur (born in 1867) and Orville (born in 1871) grew up in Dayton, Ohio, the son of a United Brethren minister. Both of their parents had college educations, and they fostered intellectual curiosity and experimentation in their children. Bishop Wright sparked his young sons' interest in flight early on by bringing them a special toy - a flying top. This toy was essentially a rubber-band powered helicopter. The boys flew it until it fell apart, and then Wilbur built his own. As they grew older, the boys spent much of their time designing, building, and selling kites.

As young adults, Wilbur and Orville capitalized on the booming popularity of bicycles by starting their own bicycle sale and repair shop. Eventually they started building their own bicycles, which was excellent training for their next enterprise: building a flying machine.

Wilbur and Orville read everything about flight that they could get their hands on in Dayton. To get more information, Wilbur wrote the Smithsonian asking for up-to-date materials on the study of flight. With the Smithsonian's help they studied Sir George Cayley's work with the four forces of flight (lift, gravity, thrust, and drag), others' experiments with gliders, and the attempts at flight made by the Smithsonian's secretary, Samuel Langley. All the work these men had done, even when they failed, proved indispensable to the Wrights' efforts. After carefully studying, Wilbur and Orville began their own scientific analysis of what was needed for flight, and began designing their own gliders. They didn't just want to put an airplane in the sky; they wanted controlled flight, and for this they needed to master the three axes of motion: pitch, roll, and yaw.

Pitch is the up and down motion of the airplane's nose (climbing or diving). Roll is the airplane rolling from side to side, causing its wings to tilt up or down. This is especially necessary for turns. When an airplane turns left, it doesn't just remain level; the left wing will dip down and the right wing will be raised up. The last of the three axes is yaw, which is the airplane's right and left movement.

Orville and Wilbur realized that birds control pitch, roll, and yaw by adjusting the shape of their wings. The brothers tried to mimic this by developing what they called 'wing warping,' a system of wires and pulleys that manipulated the glider wings to allow banking turns to the left and right. At first the wing warping was controlled with the pilot's feet, but eventually they designed a hip cradle, which was easier to use. The pilot shifted his hips right, the wires pulled the left wingtips up, and the glider banked to the right. Wing warping took care of roll; their front elevator controlled pitch, and eventually the brothers controlled yaw by connecting wires from a rudder to the hip cradle.

In the autumn of 1900, the Wrights packed up a glider and set up camp at a deserted and windy beach outside of Kitty Hawk, NC. For three weeks they flew their glider as a kite, before trying to pilot it. Though they didn't achieve as much lift as they expected based on the lift tables established by aviation researchers, they were very happy with the results of their first Kitty Hawk visit. Their best flight lasted 15 seconds and covered 300 feet.

1901 saw the brothers back at Kitty Hawk, this time with an upgraded glider. The flight tests did not go as they had hoped. The new glider proved much more difficult to control, and they simply could not get the amount of lift they were trying for. They went home to Dayton discouraged and ready to give up. Men will certainly fly, they thought, but not in our lifetime. In the end, they decided to persevere. The lift tables widely accepted by the other pioneers in flight must be wrong. The Wrights decided to test the tables; they built their own wind tunnel in the back of their bicycle shop, and observed its effects on 200 different types of miniature wings.

With the information they gathered from their wind tunnel experiments, the brothers built yet another glider for testing in 1902. This was the first flying machine that had controls for all three axes of motion. It flew smoothly, was controlled easily, and glided more than 600 feet several times. They had a maneuverable aircraft; now they needed power.

True to form, the Wrights decided to build their own engine for their plane (named 'The Flyer'). The finished product put out 12 horsepower and weighed 180 lb (the entire plane weighed 605 lbs). Then came the real challenge: designing propellers. One of their greatest contributions to aviation turned out to be their pioneer research on propellers. Their final product had 70% efficiency, which is nearly as good as modern propel ers! Back at Kitty Hawk in the fall of 1903, they began assembling The Flyer. Bad weather and damage to the plane delayed flying for several months, but finally in mid-December they were ready. Because wheels would make the plane too heavy, the Wrights constructed a wooden track for the plane to move on when taking off. On December 17th, Orville climbed onto The Flyer and started the engine. It moved down the track and lifted into the air. That first flight last only 12 seconds and covered 120 feet, but it was still the first-ever controlled, heavier-than-air flight. The brothers flew the plane four times that day, and the fourth time Wilbur flew for 59 seconds, covering 852 feet.

After this breakthrough the Wrights continued to improve their plane. Now that they weren't dependent on the winds for power, they left the beaches of Kitty Hawk and moved their work to an Ohio field. By 1905, Wilbur was flying laps around the field: 24.5 miles in 39 minutes. In spite of this success, the brothers couldn't find a buyer for their invention. They decided to stop flying until they could get a sales contract. Three years later, in 1908, they received offers from the French and from the U.S. Army. Wilbur packed up a plane and went to France, where he became something of a celebrity by flying figure eights and taking up passengers (this later model had two seats). Orville demonstrated his plane for the U.S. Government and impressed them with his altitude of 300 feet, hour-long flights and average speed of 42.58 miles. They paid him $30,000 for the plane.

The age of aviation had 'taken off,' so to speak. Just 44 years after that first powered flight, airplanes began flying faster than the speed of sound; in another 14 years men were flying in space; another eight years after that they were walking on the moon. The Wright brothers' passion and perseverance laid the foundation for this astonishing and speedy technological advance.

Science Projects: Technology Experiments

Make a Light Bulb

Thomas Edison tried thousands of experiments when he was inventing the incandescent light bulb. You can experiment too, and find out how a light bulb really works, by making your own! You will need a glass canning jar with a lid, three feet of insulated copper wire, a 6-volt battery, and thin iron wire (unraveled picture hanging wire works great).

Cut the copper wire into two equal sections. Strip at least one inch of insulation off the ends of each length of wire. Next, punch two holes in the jar lid (you can use a nail for this). Thread a wire through each hole in the lid. Make a hook at the end of each wire (the end that will be inside the jar when you put the lid on). Twist two or three strands of iron wire together, then twist the ends around the hooks in the copper wire. The iron wire will act as your filament.

Place the lid (with the filament) in the jar and carefully connect the free ends of the copper wire to the 6-volt battery. Once both ends are connected, the current should start flowing, causing the filament to heat up and give off a bright orange glow. Your homemade light bulb is working! (Note: once your filament is burned out, don't touch it right away - it will be very hot.)

Whatever its origins, American imperialism experienced its pinnacle from the late 1800s through the years following World War II. During this "Age of Imperialism," the United States exerted political, social, and economic control over countries such as the Philippines, Cuba, Germany, Austria, Korea, and Japan.

Between 1880 and 1900, cities in the United States grew at a dramatic rate. Owing most of their population growth to the expansion of industry, U.S. cities grew by about 15 million people in the two decades before 1900. Many of those who helped account for the population growth of cities were immigrants arriving from around the world. A steady stream of people from rural America also migrated to the cities during this period. Between 1880 and 1890, almost 40 percent of the townships in the United States lost population because of migration.

Industrial expansion and population growth radically changed the face of the nation's cities. Noise, traffic jams, slums, air pollution, and sanitation and health problems became commonplace. Mass transit, in the form of trolleys, cable cars, and subways, was built, and skyscrapers began to dominate city skylines. New communities, known as suburbs, began to be built just beyond the city. Commuters, those who lived in the suburbs and traveled in and out of the city for work, began to increase in number.

Many of those who resided in the city lived in rental apartments or tenement housing. Neighborhoods, especially for immigrant populations, were often the center of community life. In the enclave neighborhoods, many immigrant groups attempted to hold onto and practice precious customs and traditions. Even today, many neighborhoods or sections of some of the great cities in the United States reflect those ethnic heritages.

During the final years of the 1800s, industrial cities, with all the problems brought on by rapid population growth and lack of infrastructure to support the growth, occupied a special place in U.S. history. For all the problems, and there were many, the cities promoted a special bond between people and laid the foundation for the multiethnic, multicultural society that we cherish today.

Deeply in love, Ferdinand chose to marry Sophie Chotek in 1900 despite the opposition of his uncle, Austro-Hungarian Emperor Franz Josef, who refused to attend their wedding. Though not exactly a commoner, Sophie came from a family of obscure Czech nobles and not from a reigning or formerly reigning dynasty of Europe. As a result, her and Ferdinand's children were declared ineligible for the throne. Sophie also became the victim of countless petty slights. At imperial banquets, for example, she entered each room last, without an escort, and was then seated far away from her husband at the dinner table.

His marriage notwithstanding, Ferdinand remained Franz Josef's heir and inspector general of the army. In that capacity, he agreed to attend a series of June 1914 military exercises in Bosnia-Herzegovina. Austria-Hungary had just annexed these provinces a few years earlier against the wishes of neighboring Serbia, which likewise coveted them. Ferdinand believed the Serbs to be "pigs," "thieves," "murderers" and "scoundrels." Yet he had opposed annexation for fear that it would make an already turbulent political situation even worse. Formerly controlled by the Ottoman Empire, Bosnia-Herzegovina's population was roughly 40 percent Serb, 30 percent Muslim and 20 percent Croat, with various other ethnicities making up the remainder.

Upon learning of Ferdinand's upcoming visit, the Young Bosnians, a secret revolutionary society of peasant students, began plotting to assassinate him. In May, Gavrilo Princip, Trifko Grabez and Nedeljko Cabrinovic traveled to the Serbian capital of Belgrade, where they received six handheld bombs, four semi-automatic pistols and cyanide suicide capsules from members of the so-called Black Hand, a terrorist group with close ties to the Serbian army. After practicing with their pistols in a Belgrade park, the three men journeyed back to Bosnia-Herzegovina, receiving help from Black Hand associates to smuggle their weapons across the border. To this day, it remains unclear whether the Serbian government participated in the scheme.

Ferdinand and Sophie departed their estate for Bosnia-Herzegovina on June 23. Having received multiple warnings to cancel the trip, the archduke knew that danger potentially awaited them. "Our journey starts with an extremely promising omen," he purportedly said when the axles on his car overheated. "Here our car burns, and down there they will throw bombs at us." After arriving at a spa town a few miles outside of Sarajevo, Bosnia-Herzegovina's capital, Ferdinand attended two days of military exercises while Sophie visited schools and orphanages. On a whim, the couple drove in one evening to check out Sarajevo's bazaars. While there, they attracted a crowd of onlookers, including Princip, but were apparently treated with warmth and politeness.

Following a banquet with religious and political leaders, only one day of events remained before Ferdinand and Sophie were to return home. That morning, June 28, the archduke sent a telegram to his eldest son congratulating him on his latest exam results. He and Sophie then boarded a train for the short ride into Sarajevo. For once, Sophie was permitted to walk alongside Ferdinand during a brief troop inspection, after which the couple got in an open-topped car for a motorcade ride to city hall. The car in front of them was supposed to carry six specially trained officers but instead had only one, plus three local policemen. In fact, throughout the trip, Austro-Hungarian officials allegedly focused more attention on dinner menus than security details.

Meanwhile, seven Young Bosnians had fanned out along the Appel Quay, a main avenue in Sarajevo running parallel to the Miljacka River. When the motorcade passed by, its route having been published in advance, Cabrinovic asked which car carried the archduke. He then hurled his bomb at the car, only to watch it bounce off the folded-up roof and roll underneath the wrong vehicle. The subsequent explosion wounded two army officers and several bystanders but left Ferdinand and Sophie essentially unharmed. Cabrinovic jumped into the mostly dry riverbed and made a half-hearted attempt to kill himself before being apprehended. "I am a Serbian hero," he purportedly shouted as the police led him away. At least two other Young Bosnians also had good looks at the archduke but apparently lost the nerve to attempt an assassination.

Rather than immediately flee Sarajevo, Ferdinand decided to continue on to the planned event at city hall. Upon finishing that up, he insisted on visiting the wounded officers in the hospital. In order to dissuade any other bomb throwers, the motorcade zipped down the Appel Quay at high speeds. By mistake, however, the first three cars turned onto a side street right where Princip happened to be standing. As the cars attempted to reverse back onto the Appel Quay, Princip whipped out his pistol and fired two shots at the archduke from point-blank range, piercing him in the neck and also striking Sophie's abdomen. "Sophie, Sophie, don't die-stay alive for our children," Ferdinand murmured. Within minutes, though, both had passed away. Princip, a slender, 19-year-old Serbian army reject, later admitted to killing Ferdinand but said he had not meant to hit Sophie. Three weeks too young for the death penalty, Princip was given a 20-year sentence, but contracted tuberculosis and died in jail in April 1918, at the age of just 23.

With tensions already running high among Europe's powers, the assassination precipitated a rapid descent into World War I. First, Austria-Hungary gained German support for punitive action against Serbia. It then sent Serbia an ultimatum, worded in a way that made acceptance unlikely. Serbia proposed arbitration to resolve the dispute, but Austria-Hungary instead declared war on July 28, 1914, exactly a month after Ferdinand's death. By the following week, Germany, Russia, France, Belgium, Montenegro and Great Britain had all been drawn into the conflict, and other countries like the United States would enter later. Overall, more than 9 million soldiers and nearly that many civilians would die in fighting that lasted until 1918.

The Assassination of Archduke Franz Ferdinand, 100 Years Ago

World War I shaped our world in many, many, many ways. And it's important to realize it wasn't that long ago. It was not even 100 years ago. But it was really the end of the more traditional empires. It was the end of kingdoms. It really reshaped much of the globe much more around states defined by nations rather than states defined by monarchies or states defined by empires. And it was also the first war where technology, or I would say modern technology-- technology has always played a major role in wars. In fact, wars have been a catalyst for technology often. But it was the first time that much of what we consider to be modern technology played a huge role in the actual carrying out of the war. And to a large degree, this is what made the war so much bloodier, and one could argue, even more protracted. So here I have a bunch of pictures of the various technologies used in World War I. Here in this picture you have a machine gun, which obviously allows you to indiscriminately mow down folks. These guys, it looks like they might be in some type of a trench. And so you could imagine that combination if viewed from above. So let's say that this is a trench. This is a trench right over here. We're looking from above. So there's some people sitting in the trench. A couple of these folks have machine guns. The rest of the guys just have rifles over here. If you wanted to storm this trench, you'd be in a bad situation. The guy with the machine gun essentially could just mow people down. They also tended to use barbed wire. Barbed wire wasn't invented in World War I. It was invented many decades before in the 1800s. But that would make it very hard for someone to cross this period. They would get stuck in it. At which point these guys in the trench could shoot him down. And it would be very hard to shoot the guys in the trench. So it also, other than making it very deadly, it gave all the advantages to the defense. So any time someone wanted to gain ground, especially in one of the fronts where trench warfare was being used, it was a hugely, hugely, hugely bloody affair. The other technology that came into mainstream use in World War I was the use of gas, and in particular poison gas. And as you see these gentleman right over here, they're wearing gas masks because they're afraid that their opponent is going to use poison gas. And the benefit of gas in particular is let's say you have an artillery shell that you throw over and it doesn't hit anybody. But then it starts releasing a canister of-- let me do that in a different color-- it starts releasing a canister of gas. So the gas I've drawn in this purplish color. And so it doesn't have to be a direct hit. It can just linger there and infect that trench. And it'll affect everyone there. And gas warfare was-- actually, the Germans weren't first to use just gas warfare. But they were the first to use very lethal, what we would call poison, gas. And in particular in 1915, they used chlorine gas. So let me write that down. Chlorine gas, which immediately attacks the respiratory system of the person who inhales it. And they essentially choke to death within seconds or minutes. They also used phosgene gas because this did not stimulate that choking. And in some ways it could infiltrate the respiratory system even more. It had a delayed effect. So it would linger around. And you have the use of mustard gas. Mustard gas was very hard to protect against. It wouldn't immediately have you choke to death like chlorine gas. It would be severe blistering. It would essentially take you out of the battle. It was very hard to protect against. And it would also linger around in the trench. So it made the trench a very toxic environment to work in. So these are very, very, very ugly weapons. I mean, war itself is ugly. Weapons themselves are ugly. I mean, the machine gun is not a pleasant weapon. It can mow people down. But even folks who view something like a machine gun as an acceptable thing tend to view these things as particularly ugly things to use. Other weapons that showed up in World War I, we talked about this in other videos, but the tank started to become a factor. This right over here is an American tank. Obviously, with these treads it can go in tough terrain. It's heavily, heavily armored. When you talk about this trench type of thing, well, if you've got a big hulking beast, maybe that could roll through the barbed wire and take some beating and maybe eventually-- so you could imagine a tank over here, it could eventually-- and actually the tanks at this time did not have these big turrets. So they might have looked something more like that. But this might be able to actually be part of an offensive against a trench like this. We've talked extensively about submarine warfare in World War I. The Germans especially used it, essentially to have a chance against the dominant British Navy. Unrestricted U-boat warfare was one of the primary reasons given by the Americans as to why they entered the war on the side of the entente. These are World War I era US submarines, just to give an idea of how they actually looked. And in some ways the best foreshadowing of what would play a major, major, major role in future wars it was the bringing of heavier than air craft into the war. So in particular, we're talking about airplanes. So before this, you had stuff like balloons and zeppelins used for reconnaissance, used to see where we should aim the artillery, things like that. But now you had the Wright brothers only, frankly, several years before inventing the engine powered heavier than air craft. And at first the airplane, in the beginning stages the war, was used for reconnaissance. But as the technology improved, as the engines improved, it started to be used for bombing. It started to actually used for air to air combat. And out of all of the folks involved in air to air combat, this gentleman right over here is probably the most famous. Although you might not recognize his name. He's been turned into a bit of a caricature in the modern world. But this is Manfred von Richthofen. And he was a pilot for the Germans. And he's more famously known as the Red Baron. And he was called the Red Baron because he was actually a Baron. It is a title of nobility in imperial Germany. And he painted his plane red. So this is a picture of his plane right over here. So if I were to color it in-- I guess this isn't quite red. I should actually probably try to get a more reddish color. So maybe this is more of a red. So this is obviously a black and white photograph, but maybe if I color it in for you, you'll get more of the feeling of what his plane might have looked like. And it was a triplane. It had these three wings right over here, or three levels of wings. So whatever, his plane was red. That's why he was called the Red Baron. And he was famous for being the most lethal pilot in all of the war. He has 80 confirmed kills. He was able to down 80 enemy aircraft. So 80 confirmed wins, I guess you can say in combat, which is more than any other folks in World War I. So very, very famous pilot. He himself-- when you're talking about any of the combatants in World War I did not have a long life expectancy. The pilots especially this was a dangerous game. And he also, despite being the top pilot, the top ace, amongst all the pilots in World War I, he also ended up getting shot in the air in 1918. He literally got shot through the lungs and the heart. He somehow managed to land his plane. And when the people ran up to him, the accounts say, that his famous last words as he died, right when they ran up to him, was "kaput". So interesting. And on top of that, he's now been turned into a bit of a caricature. I mean, us in the West, in the US, we recognize the brand Red Baron pizza. It is named for the Red Baron, for Manfred von Richthofen. Kind of a strange name, I think, for a pizza company. I mean, he's not even Italian. But that's, I guess, what we know him for. But you see, this guy right over here looks a lot more like Tom Selleck than look like the real Manfred von Richthofen.

The End of World War I

The armistice that ended World War I went into effect at 11 a.m. on November 11, 1918. After four and a half years, the war was finally over, but the results remained. Devastation was everywhere. People's homes and lands were destroyed. Large areas of France had been reduced to rubble. Cities, like Flanders and Ypres in Belgium, were nearly wiped off the map.

The war's human toll was even more devastating. Millions of soldiers for the Allied Powers of Great Britain, France, and the United States were killed, wounded, or missing. The Central Powers of Germany, Austria-Hungary, Turkey, and Bulgaria lost even more men. Countless civilians also lost their lives or loved ones. Now, in 1918, the Allied Powers emerged victorious, and they were ready to make Germany pay.

Peace Negotiations

The Paris Peace Conference opened on January 18, 1919, with the goal of developing a treaty that would punish Germany and meet the goals of the various Allied Powers. Negotiating the treaty, which would be known as the Treaty of Versailles, was a long and complex process. At first, the Council of Ten, consisting of the heads of state and foreign ministers of ten Allied Powers, tried to hammer out a deal. The Council soon proved to be too large, and its members had too many conflicting opinions. By March, the treaty negotiations were being handled by the Big Four, namely, the United States, Great Britain, France, and Italy. Italy soon dropped out of the process when its representative became angry that his demands for more territory were rejected.

Only the Big Three were left: the United States, led by President Woodrow Wilson; Great Britain, led by Prime Minister David Lloyd George; and France, led by Prime Minister Georges Clemenceau. Each of these men had a different view of what peace should look like and how Germany should be treated. Wilson was interested in building a world trade network, avoiding war in the future, proposing his Fourteen Points for a better world, and avoiding harsh treatment of Germany. George was also looking ahead to potential world trade, but he wanted Germany to pay reparations. Clemenceau, whose country suffered some of the worst damage during the war, desired large-scale reparations from Germany and a demilitarized zone between France and Germany in case of future German aggression.

The Terms of the Treaty of Versailles

After months of debate and lots of hard work, the Big Three created a treaty with the following provisions:

Economists and historians are still debating the causes of the Great Depression. While we know what happened, we have only theories to explain the reason for the economic collapse. This overview will arm you with knowledge of the political events that may have helped cause the Great Depression.

What Was The Great Depression?

Before we can explore the causes, we first need to define what we mean by the Great Depression.
The Great Depression was a global economic crisis that may have been triggered by political decisions including war reparations post-World War I, protectionism such as the imposition of congressional tariffs on European goods or by speculation that caused the Stock Market Collapse of 1929. Worldwide, there was increased unemployment, decreased government revenue and a drop in international trade. At the height of the Great Depression in 1933, more than a quarter of the U.S. labor force was unemployed. Some countries saw a change in leadership as a result of the economic turmoil.

When Was The Great Depression?

In the United States, the Great Depression is associated with Black Tuesday, the stock market crash of October 29, 1929, although the country entered a recession months before the crash. Herbert Hoover was the President of the United States. The Depression continued until the onset of World War II, with Franklin D. Roosevelt following Hoover as president.

Possible Cause: World War I

The United States entered World War I late, in 1917, and emerged as a major creditor and financier of post-War restoration. Germany was burdened with massive war reparations, a political decision on the part of the victors. Britain and France needed to rebuild. U.S. banks were more than willing to loan money. However, once U.S. banks began failing the banks not only stopped making loans, they wanted their money back. This put pressure on European economies, which had not fully recovered from WWI, contributing to the global economic downturn.

Possible Cause: The Federal Reserve

The Federal Reserve System, which Congress established in 1913, is the nation's central bank, authorized to issue the Federal Reserve notes that create our paper money supply. The "Fed" indirectly sets interest rates because it loans money, at a base rate, to commercial banks.
In 1928 and 1929, the Fed raised interest rates to try to curb Wall Street speculation, otherwise known as a "bubble." Economist Brad DeLong believes the Fed "overdid it" and brought on a recession. Moreover, the Fed then sat on its hands:

"The Federal Reserve did not use open market operations to keep the money supply from falling.... [a move] approved by the most eminent economists."

There was not yet a "too big to fail" mentality at the public policy level.

Possible Cause: Black Thursday (or Monday or Tuesday)

A five-year bull market peaked on September 3, 1929. On Thursday, October 24, a record 12.9 million shares were traded, reflecting panic selling. On Monday, October 28, 1929, panicked investors continued to try to sell stocks; the Dow saw a record loss of 13 percent. On Tuesday, October 29, 1929, 16.4 million shares were traded, shattering Thursday's record; the Dow lost another 12 percent.
Total losses for the four days: $30 billion, 10 times the federal budget and more than the $32 billion the U.S. had spent in World War I. The crash wiped out 40 percent of the paper value of common stock. Although this was a cataclysmic blow, most scholars do not believe that the stock market crash, alone, was sufficient to have caused the Great Depression.

Possible Cause: Protectionism

The 1913 Underwood-Simmons Tariff was an experiment with lowered tariffs. In 1921, Congress ended that experiment with the Emergency Tariff Act. In 1922, the Fordney-McCumber Tariff Act raised tariffs above 1913 levels. It also authorized the president to adjust tariffs by 50% to balance foreign and domestic production costs, a move to help America's farmers.
In 1928, Hoover ran on a platform of higher tariffs designed to protect farmers from European competition. Congress passed the Smoot-Hawley Tariff Act in 1930; Hoover signed the bill although economists protested. It is unlikely that tariffs alone caused the Great Depression, but they fostered global protectionism; world trade declined by 66% from 1929 to 1934.

Possible Cause: Bank Failures

In 1929, there were 25,568 banks in the United States; by 1933, there were only 14,771. Personal and corporate savings dropped from $15.3 billion in 1929 to $2.3 billion in 1933. Fewer banks, tighter credit, less money to pay employees, less money for employees to buy goods. This is the "too little consumption" theory sometimes used to explain the Great Depression but it, too, is discounted as being the sole cause.

Effect: Changes In Political Power

In the United States, the Republican Party was the dominant force from the Civil War to the Great Depression. In 1932, Americans elected Democrat Franklin D. Roosevelt (" New Deal"); the Democratic Party was the dominant party until the election of Ronald Reagan in 1980.
Adolf Hilter and the Nazi party (National Socialist German Workers' Party) came into power in Germany in 1930, becoming the second largest party in the country. In 1932, Hitler came in second in a race for president. In 1933, Hitler was named Chancellor of Germany.

Japan Rivals the U.S.

'Yesterday, December 7th, 1941 - a date which will live in infamy - the United States of America was suddenly and deliberately attacked by naval and air forces of the Empire of Japan.'

But, to say it came as a complete shock would not be the whole story - the United States and Japan had been at odds for decades. First of all, just after the turn of the century, both nations were competing for political and economic influence throughout the Pacific. Then, after World War I, Japan laid claim to former German colonies in the East, expanding the Japanese Empire and emerging as a serious rival to America's position in Asia.

In 1922, the world's nine largest naval powers (including Japan and the United States) signed a series of treaties limiting warship capacity, agreeing to consult each other in any disputes over China and respecting the territorial integrity of that nation. But certain classes of ships weren't restricted by the Nine Power Treaty, leading to an arms race until the loopholes were closed.

Then, in 1931, Japan blatantly violated these agreements by invading Manchuria and other parts of China. With the Nine Power Treaty now broken, America increased its naval power in the Pacific and several nations began funneling aid to China through their colonies in Asia.

Undeclared War

Continued Japanese aggression for the next decade, including the invasion of China in 1937, their alliance with the Axis powers of World War II and the invasion of French Indochina resulted in escalating American involvement without a declaration of war. Concerned American pilots formed an independent air force called the Flying Tigers and worked with the Chinese government to prepare defenses over that nation's airspace. The U.S. government also joined its allies in seizing Japanese assets and placed embargoes on steel, oil and other raw materials needed for war production.

Running short on supplies, Japan had two choices: submit to foreign demands by abandoning the invasion of China or seize the resources it needed by attacking even more territory. Japan chose the latter. With the European powers already embroiled in World War II, it looked like the only thing standing in Japan's way of controlling the entire Pacific Rim was the United States.

The Empire of Japan devised an elaborate plan to simultaneously attack Allied territories throughout the Pacific, including Hawaii, the Philippines, Wake Island, Guam, Malaya, Thailand, Hong Kong and Midway. In one sweep, they could secure desperately needed resources, discourage foreign interference and cripple America's increasing military strength in the Pacific.

To Pearl Harbor alone, Japan sent 30 ships, including 6 aircraft carriers. There was a separate force of submarines tasked with sinking any American ships that might escape the harbor. The top-secret Japanese fleet set sail on November 26, 1941, and by avoiding shipping lanes, moved into position without being spotted.

Warning Signs

Although the Allies had not yet broken the Japanese naval encryption code, there were suggestions of an impending attack. Beginning as early as January 1941 and periodically throughout the year, Washington sent warnings to fleet and field commanders in Hawaii, the Philippines, Alaska and the Panama Canal Zone. But many American decision-makers believed that Japan did not have the military capacity to pull off a major strike.

The day after the Japanese fleet embarked, a message went out to all Pacific stations reading, 'Consider this dispatch a war warning.' Many expected an attack on the Philippines to be most likely. However, minimal steps were taken in Hawaii. Most importantly, the aircraft carriers were all sent out, and in a fatal miscalculation, the Army commander lined up his planes as a protection against sabotage.

In order to achieve complete surprise, Japan violated international law and diplomatic protocol by attacking without first sending an ultimatum. Still, in the wee hours of December 7, 1941, there were at least three clues of imminent danger.

First, an American patrol spotted a submarine periscope as it followed a cargo ship through the anti-submarine nets into Pearl Harbor. A nearby destroyer, the USS Ward, fired at the mini-sub and sank it. Second, a radar operator noticed the incoming Japanese air force, but officers were expecting planes from California that morning and dismissed the sighting. Third, Washington forwarded credible intelligence of an attack, but it didn't reach the commander at Pearl Harbor until hours later.

'Yesterday, December 7th, 1941 - a date which will live in infamy - the United States of America was suddenly and deliberately attacked by naval and air forces of the Empire of Japan.' But, to say it came as a complete shock would not be the whole story - the United States and Japan had been at odds for decades.
