This week, we're continuing our discussion of heroes by talking about Gilgamesh, star of one of the earliest written hero stories, The Epic of Gilgamesh. Gilgamesh was a terrible ancient king who left his kingdom seeking adventure, and eventually on the prowl for immortality. Along the way, he checks pretty much all the boxes on the checklist of Joseph Campbell's Hero's Journey.

In which John Green teaches you about the economic malaise that beset the United States in the 1970s. A sort of perfect storm of events, it combined the continuing decline of America's manufacturing base and the oil shocks of 1973 and 1979, and brought about an stagnant economy, paired with high inflation. Economists with a flair for neologisms and portamenteau words called this "stagflation," and it made people miserable. Two presidential administrations were scuttled at least in part by these economic woes; both Gerald Ford and Jimmy Carter are considered failed presidents for many reasons, but largely because of an inability to improve the economy. (hint: In reality, no one person can materially change something as big as the world economy, even if they are president, but one person sure can make a handy scapegoat!) So, by and large, the 70s were a pretty terrible time in America economically, but at least the decade gave us Mr. Green.

In which John Green teaches you about the poetry of Sylvia Plath. When a lot of people think about Sylvia Plath, they think about her struggles with mental illness and her eventual suicide. Her actual work can get lost in the shuffle a bit, so this video really tries to focus on the poetry. You'll learn about Sylvia Plath's role as a feminist poet, and you'll also learn about her extraordinary ability to recreate the experiences of real life in beautiful and relatable way.

Hear John read all of Sylvia Plath's "Lady Lazarus" here:

In which John Green returns for a dystopian new season of Crash Course Literature! We're starting with George Orwell's classic look at the totalitarian state that could be in post-war England. Winston Smith is under the eye of Big Brother, and making us think about surveillance, the role of government, and how language can play a huge part in repressive regimes.

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.

Hey teachers and students - Check out CommonLit's free collection of reading passages and curriculum resources to learn more about the events of this episode. 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

Today we are exploring some of its key parts, including vital nutrients -- such as water, vitamins, minerals, carbs, fats, and proteins -- as well as how anabolic reactions build structures and require energy, while catabolic reactions tear things apart and release energy.

In which John Green teaches you about the Progressive Presidents, who are not a super-group of former presidents who create complicated, symphonic, rock soundscapes that transport you into a fantasy fugue state. Although that would be awesome. The presidents most associated with the Progressive Era are Theodore Roosevelt, William Taft, and Woodrow Wilson. During the times these guys held office, trusts were busted, national parks were founded, social programs were enacted, and tariffs were lowered. It wasn't all positive though, as their collective tenure also saw Latin America invaded A LOT, a split in the Republican party that resulted in a Bull Moose, all kinds of other international intervention, and the end of the Progressive Era saw the United States involved in World War. If all this isn't enough to entice, I will point out that two people get shot in this video. Violence sells, they say.

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 phenomenons, 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. Which brings us to the Progressive Era, which we'll get into next week!

Hey teachers and students - Check out CommonLit's free collection of reading passages and curriculum resources to learn more about the events of this episode. The Gilded Age was marked by the success of the richest coupled with inequality and corruption. Repeated factory disasters, such as the triangle shirtwaist factory fire revealed the unsafe working conditions of the urban poor: https://www.commonlit.org/text....s/the-triangle-shirt

Jupiter is the biggest planet in our solar system. The gas giant is NOT a failed star, but a really successful planet! It has a dynamic atmosphere with belts and zones, as well as an enormous red spot that’s actually a persistent hurricane. Jupiter is still warm from its formation, and has an interior that’s mostly metallic hydrogen, and it may not even have a core.

In which John Green teaches you about the fall of the Roman Empire, which happened considerably later than you may have been told. While the Western Roman Empire fell to barbarians in 476 CE, the Byzantines in Constantinople continued the Eastern Empire nicely, calling themselves Romans for a further 1000 years. Find out what Justinian and the rest of the Byzantine emperors were up to over there, and how the Roman Empire dragged out its famous Decline well into medieval times. In addition to all this, you'll learn about ancient sports riots and hipster barbarians, too.
