    How Does Art Tell Stories? : Crash Course Art History #7

    From cave paintings to public murals, humans have told stories with art for thousands of years. In this episode of Crash Course Art History, we discover that visual storytelling is elementally human — and so is competing over whose story is told.

    The Progressive Era: Crash Course US History #27

    In which John Green teaches you about the Progressive Era in the United States. In the late 19th and early 20th century in America, there was a sense that things could be improved upon. A sense that reforms should be enacted. A sense that progress should be made. As a result, we got the Progressive Era, which has very little to do with automobile insurance, but a little to do with automobiles. All this overlapped with the Gilded Age and is a little confusing, but here we have it. Basically, people were trying to solve some of the social problems that came with the benefits of industrial capitalism. To oversimplify, there was a competition between the corporations' desire to keep wages low and workers' desire to have a decent life. Improving food safety, reducing child labor, and unions were all on the agenda in the Progressive Era. While progress was being made, and people were becoming freer, these gains were not equally distributed. Jim Crow laws were put in place in the south, and immigrant rights were restricted as well. So once again on Crash Course, things aren't so simple. 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 Progressive Era was marked by rapid reactions to the Gilded Age: https://www.commonlit.org/texts/the-progressive-era Literature such as The Jungle revealed the horrifying conditions of factory industries, one of several which were overhauled with new progressive regulations: https://www.commonlit.org/texts/excerpt-from-the-jungle Chapters: Introduction: The Progressive Era 00:00 The Progressive Era 1:06 Social Concerns of the Progressive Era 1:53 Mystery Document 2:48 The Jungle 4:04 Muckracking, Journalism, and Photography 4:22 Union Organizing 4:55 The Industrial Workers of the World 5:46 Mass Consumption Culture 6:29 The Labor Problem 7:39 Government Solutions to Social Problems 8:46 The Socialist Party 9:30 The 17th Amendment 10:17 Initiatives & Referendums 10:36 Voter Suppression & Jim Crow Laws 11:14 Plessy v.

    Growth, Cities, and Immigration: Crash Course US History #25

    In which John Green teaches you about the massive immigration to the United States during the late 19th and early 20th centuries. Immigrants flocked to the US from all over the world in this time period. Millions of Europeans moved to the US where they drove the growth of cities and manned the rapid industrialization that was taking place. In the western US many, many Chinese immigrants arrived to work on the railroad and in mines. As is often the case in the United States, the people who already lived in the US reacted kind of badly to this flood of immigrants. Some legislators tried to stem the flow of new arrivals, with mixed success. Grover Cleveland vetoed a general ban on immigration, but the leadership at the time did manage to get together to pass an anti-Chinese immigration law. Immigrants did win some important Supreme Court decisions upholding their rights, but in many ways, immigrants were treated as second-class citizens. At the same time, the country was rapidly urbanizing. Cities were growing rapidly and industrial technology was developing new wonders all the time. John will cover all this upheaval and change, and hearken back to a time when racial profiling did in fact boil down to analyzing the side of someone's face. 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. As America industrialized further and manufacturing grew, a rush of new immigrants came to America seeking job opportunities: https://www.commonlit.org/texts/the-rush-of-immigrants Immigrants often entered through New York's Ellis Island where the Statue of Liberty bore the iconic phrase "Give me your tired, your poor,": https://www.commonlit.org/texts/the-new-colossus Immigrants experienced culture shock and hard living conditions during this time, as documented in later memoirs such as "America and I": https://www.commonlit.org/texts/america-and-i Chapters: Introduction 00:00 The Agricultural Golden Age 0:39 Americans Move to Cities 1:54 New York City & Chicago 2:41 The Rise of Immigration 3:21 Immigrant Cities 4:05 Southern & Eastern European Immigrants 5:30 Chinese Immigrants 6:31 Mass Immigration: A Global Phenomenon 7:44 Mystery Document 8:34 Why Did Immigrants Come to America? 9:36 Living Conditions in Immigrant Cities 10:02 Wealth Segregation 11:00 Credits 12:12 Crash Course is on Patreon!

    The Civil War Part 2: Crash Course US History #21

    In which John Green teaches you how the Civil War played a large part in making the United States the country that it is today. He covers some of the key ways in which Abraham Lincoln influenced the outcome of the war, and how the lack of foreign intervention also helped the Union win the war. John also covers the technology that made the Civil War different than previous wars. New weapons helped to influence the outcomes of battles, but photography influenced how the public at large perceived the war. In addition, John gets into the long-term effects of the war, including the federalization and unification of the United States. All this plus homesteading, land grant universities, railroads, federal currency, and taxes. Check out the US National Archives Flickr.

    The Vikings! - Crash Course World History 224

    In which John Green teaches you about Vikings! That's right, one of our most requested subjects, the Vikings, right here on Crash Course. So what's the deal with Vikings? Well, the stuff you've heard about them may not be true. The Vikings weren't just pagan raiders striking terror into the hearts of defenseless European Christendom. They were some of the greatest travelers of their time, and they weren't always traveling to steal. In a lot of cases, they were traveling to trade. John will teach you about Viking trade goods, Norse Mythology, and yes, there will be blood, guts, and dragons. OK? Crash Course is on Patreon!
