Many organizations have made it their mission to expand the rights of Black Americans. The NAACP and the Urban League are examples of influential organizations with long histories. But a long history or extensive membership isn't always necessary to have an impact. Today, we'll learn about the Black Panthers. They were a relatively small, relatively short-lived political party that had an outsized impact on US history.

In which John Green teaches you where American politicians come from. In the beginning, soon after the US constitution was adopted, politics were pretty non-existent. George Washington was elected president with no opposition, everything was new and exciting, and everyone just got along. For several months. Then the contentious debate about the nature of the United States began, and it continues to this day. Washington and his lackey/handler Alexander Hamilton pursued an elitist program of federalism. They attempted to strengthen the central government, create a strong nation-state, and leave less of the governance to the states, They wanted to create debt, encourage manufacturing, and really modernize the new nation/ The opposition, creatively known as the anti-federalists, wanted to build some kind of agrarian pseudo-paradise where every (white) man could have his own farm, and live a free, self-reliant life. The founding father who epitomized this view was Thomas Jefferson. By the time Adams became president, the anti-federalists had gotten the memo about how alienating a name like anti-federalist can be. It's so much more appealing to voters if your party is for something rather than being defined by what you're against, you know? In any case, Jefferson and his acolytes changed their name to the Democratic-Republican Party, which covered a lot of bases, and proceeded to protest nearly everything Adams did. Lest you think this week is all boring politics, you'll be thrilled to hear this episode has a Whiskey Rebellion, a Quasi-War, anti-French sentiment, some controversial treaties, and something called the XYZ Affair, which sounds very exciting. Learn all about it this week with John Green.

Much of America's politics came from debates between democratic republican Thomas Jefferson and federalist Alexander Hamilton: https://www.commonlit.org/texts/alexander-hamilton
While Jefferson would go on to become president, Hamilton heavily influenced President George Washington who set many American political ideals in his farewell address that Hamilton helped craft: https://www.commonlit.org/text....s/washington-s-farew

The Harlem Renaissance was one of the richest, most vibrant, and most culturally generative artistic periods in American history and the work that emerged from that period continues to shape the landscape of American arts and letters today. In this episode, we’re going to explore some of the writers, artists, and musicians who turned Harlem into a world-renowned hub of art and culture, and delve into the factors that brought them all together in the first place.

In which John Green teaches you about the American Revolution. And the Revolutionary War. I know we've labored the point here, but they weren't the same thing. In any case, John will teach you about the major battles of the war, and discuss the strategies on both sides. Everyone is familiar with how this war played out for the Founding Fathers; they got to become the Founding Fathers. But what did the revolution mean to the common people in the United States? For white, property-owning males, it was pretty sweet. They gained rights that were a definite step up from being British Colonial citizens. For everyone else, the short-term gains were not clear. Women's rights were unaffected, and slaves remained in slavery. As for poor white folks, they remained poor and disenfranchised. The reality is it took a long time for this whole democracy thing to get underway, and the principles of life, liberty, and the pursuit of happiness weren't immediately available to all these newly minted Americans.

World War I was a total war for millions of people in Europe. Many men were enlisted in the fighting, but the war work had implications for the daily lives of a huge number of Europeans. Women entered the workforce in huge numbers, and for a lot of people, the battles raged through their towns, cities, and even their homes.

In addition to learning about the homefronts of the war, we're going to look at how the war ended, and how the Paris Peace Conference and the treaties that resulted did little to heal the societal wounds of the war, and in many ways set the stage for the next big war.

Today we're going to learn about perhaps the best-known leader in the Civil Rights Era, Martin Luther King, Jr. From his rise to notoriety during the Montgomery Bus Boycott in 1955, his leadership of the Southern Christian Leadership Conference, the March on Washington in 1963, his work toward the Civil Rights and Voting Rights Acts of the mid-1960s, and his assassination in 1968, Dr. King is very broadly known. But maybe he isn't that well understood. Like many extremely famous people, Martin Luther King can sometimes be drawn as a bit of a flat character, and his ideas can be reduced to platitudes. Today we'll try to give you a fuller picture of the man and leader he was.

In 1910, 90% of Black Americans lived in the South. By 1940, around 1.5 million Black Americans had left their homes, and 77% lived in the South. By 1970, 52% of Black Americans remained in the South. People moved away for many reasons, including increased opportunity in the more industrial North and West. They sought a relatively safer life away from the lynchings and violence that were concentrated in the South. This Great Migration shaped 20th-century America in countless ways, but we're going to try to count some of them in this video.

#crashcourse #history #blackhistory

In which John Green teaches you about the Gilded Age and its politics. What, you may ask, is the Gilded Age? The term comes from a book by Mark Twain and Charles Dudley Warner titled, "The Gilded Age." You may see a pattern emerging here. It started in the 1870s and continued on until the turn of the 20th century. The era is called Gilded because of the massive inequality that existed in the United States. Gilded Age politics were marked by a number of phenomena, most of them having to do with corruption. On the local and state level, political machines wielded enormous power. John gets into details about the most famous political machine, Tammany Hall. Tammany Hall ran New York City for a long, long time, notably under Boss Tweed. Graft, kickbacks, and voter fraud were rampant, but not just at the local level. Ulysses S. Grant ran one of the most scandalous presidential administrations in U.S. history, and John will tell you about two of the best-known scandals, the Credit Mobilier scandal, and the Whiskey Ring. There were a few attempts at reform during this time, notably the Civil Service Act of 1883 and the Sherman Anti-trust act of 1890. John will also get into the Grange Movement of the western farmers, and the Populist Party that arose from that movement. The Populists, who threw in their lot with William Jennings Bryan, never managed to get it together and win a presidency, and they faded after 1896. This brings us to the Progressive Era, which we'll get into in the next episode!

In which John Green teaches you about the war that was supposed to end all wars. Instead, it solved nothing and set the stage for the world to be back at war just a couple of decades later. As an added bonus, World War I changed the way people look at the world, and normalized cynicism and irony. John will teach you how the assassination of an Austrian Archduke kicked off a new kind of war that involved more nations and more people than any war that came before. New technology like machine guns, airplanes, tanks, and poison gas made killing more efficient than ever. Trench warfare and modern weapons led to battles in which tens of thousands of soldiers were killed in a day, with no ground gained for either side. World War I washed away the last vestiges of 19th-century Romanticism and paved the way for the 20th-century modernism that we all know and find to be cold and off-putting. While there may not be much upside to WWI, at least it inspired George M. Cohan to write the awesome song, "Over There."

In which John Green teaches you about the (English) colonies in what is now the United States. He covers the first permanent English colony at Jamestown, Virginia, the various theocracies in Massachusetts, the feudal kingdom in Maryland, and even a bit about the spooky lost colony at Roanoke Island. What were the English doing in America, anyway? Lots of stuff. In Virginia, the colonists were largely there to make money. In Maryland, the idea was to create a colony for Catholics who wanted to be serfs of the Lords Baltimore. In Massachusetts, the Pilgrims and Puritans came to America to find a place where they could freely persecute those who didn't share their beliefs. But there was a healthy profit motive in Massachusetts as well. Profits were thin at first, and so were the colonists. Trouble growing food and trouble with the Natives kept the early colonies from success. Before long though, the colonists started cultivating tobacco, which was a win for everyone involved if you ignore the lung cancer angle. So kick back, light up a smoke, and learn how America became profitable. DON'T SMOKE, THOUGH! THAT WAS A JOKE!

Now that we’re done with the planets, asteroid belt, and comets, we’re heading to the outskirts of the solar system. Out past Neptune are vast reservoirs of icy bodies that can become comets if they get poked into the inner solar system. The Kuiper Belt is a donut shape aligned with the plane of the solar system; the scattered disk is more eccentric and is the source of short-period comets, and the Oort Cloud which surrounds the solar system out to great distances is the source of long-period comets. These bodies all probably formed closer to the Sun and got flung out to the solar system’s suburbs by gravitational interactions with the outer planets.

Today we're going to tell the story of a quiet revolution in the 1960s that shifted our entire understanding of how the Earth works. We currently believe that the Earth's broken outer shell rises from the mantle and folds back in - kind of like a dance of creative destruction and reconstruction - giving us our continents and oceans, mountains and valleys, volcanoes, and earthquakes. And it would take a group of scientists all over the world to get us this grand unifying theory of plate tectonics.

#CrashCourse #Geography #Tectonics

In which John Green explores F. Scott Fitzgerald's novel of the Jazz Age, The Great Gatsby. John introduces you to Nick Carraway, Jay Gatsby, Daisy and Tom Buchanan, and the other characters in the novel, and tries to look beyond the surface story to figure out what this thing is ABOUT. Set in the 1920s against a conflicted backdrop of prohibition and excess, The Great Gatsby takes a close look at the American Dream as it existed in Fitzgerald's time. It turns out, it had a lot to do with money and status, and it still does today. John will cover the rich symbolism of the novel, from the distant green light to the pale gold of wealth and decay. Also, Paris Hilton drops by.

In which John Green teaches you about the Little Ice Age. The Little Ice Age was a period of global cooling that occurred from the 13th to the 19th centuries. This cooling was likely caused by a number of factors, including unusual solar activity and volcanic eruptions. The Little Ice Age greatly impacted human social orders, especially during the 17th century. When the climate changed, and the weather became unpredictable, the world changed profoundly. Poor harvests led to hunger, which led to even less productivity, which even resulted in violent upheaval in a lot of places. All this from a little change in the temperature? Definitely.

Russia went and had a revolution in 1917 and cinema was a big part of its aftermath. Even though film stock was hard to come by, we saw the first film school started, and the study of film became hugely important. Russian filmmakers started trying to understand the power of the cut itself, thus developing a theory of filmmaking based solely around the juxtaposition of images: Soviet Montage. In this episode of Crash Course Film History, Craig talks us through some of the filmic things going on in post-revolution era Russia.

In which John Green teaches you about the post-World War II breakup of most of the European empires. As you'll remember from previous installments of Crash Course, Europeans spent several centuries sailing around the world creating empires, despite the fact that most of the places they conquered were perfectly happy to carry on alone. After World War II, most of these empires collapsed. This is the story of those collapses. In most places, the end of empire was not orderly, and violence often ensued. While India was a (sort of) shining example of non-violent change, in places like The Congo, Egypt, Rwanda, Vietnam, Cambodia, and Laos, things didn't go smoothly at all. John brings you all this, plus pictures of Sea Monkeys. Sadly, they don't look anything like those awesome commercials in the comic books.

Now that we’re done with the planets, asteroid belt, and comets, we’re heading to the outskirts of the solar system. Out past Neptune are vast reservoirs of icy bodies that can become comets if they get poked into the inner solar system. The Kuiper Belt is a donut shape aligned with the plane of the solar system; the scattered disk is more eccentric and is the source of short-period comets, and the Oort Cloud which surrounds the solar system out to great distances is the source of long-period comets. These bodies all probably formed closer to the Sun and got flung out to the solar system’s suburbs by gravitational interactions with the outer planets.

John Green teaches you about the so-called Dark Ages, which it turns out weren't as uniformly dark as you may have been led to believe. While Europe was indeed having some issues, many other parts of the world were thriving and relatively enlightened. John covers European Feudalism, the cultural blossoming of the Islamic world, and the scientific and artistic advances in China, all during these "Dark Ages." Along the way, John will raise questions about the validity of Europe's status as a continent, reveal the best and worst years of his life, and frankly state that science and religion were once able to coexist.

Today we're going to tell the story of a quiet revolution in the 1960s that shifted our entire understanding of how the Earth works. We currently believe that the Earth's broken outer shell rises from the mantle and folds back in - kind of like a dance of creative destruction and reconstruction - giving us our continents and oceans, mountains and valleys, volcanoes, and earthquakes. And it would take a group of scientists all over the world to get us this grand unifying theory of plate tectonics.

We’ve covered a lot of incredible stuff, but this week we’re talking about the weirdest objects in space: BLACK HOLES. Stellar-mass black holes form when a very massive star dies, and its core collapses. The core has to be more than about 2.8 times the Sun’s mass to form a black hole. Black holes come in different sizes, but for all of them, the escape velocity is greater than the speed of light, so nothing can escape, not matter or light. They don’t wander the Universe gobbling everything down around them; their gravity is only really intense very close to them. Tides near a stellar mass black hole will spaghettify you, and time slows down when you get near a black hole — not that this helps much if you’re falling in.
