  Rethinking Civilization - Crash Course World History 201 27.09.2026 17min

  In which John Green returns to teaching World History! This week, we'll be talking about the idea of civilization, some of the traditional hallmarks of so-called civilization, and why some people would choose to live outside the civilization model. It turns out that not everyone who lives outside of what we traditionally think of as a "civilized" social order is necessarily a barbarian! To defuse any tension you may be feeling, I'll just tell you now that the Mongols are back. You'll learn about Zomia, swidden agriculture, and even a little about anarchy!Crash Course is on Patreon!

  Anita Hill and Clarence Thomas: Crash Course Black American History #46 27.09.2026 16min

  Today, Clint will teach you about the Supreme Court confirmation hearing of Clarence Thomas. During the screening process, Anita Hill came forward alleging that Thomas had sexually harassed her when the two of them worked together at the Department of Education. The public response to Hill's allegations was tense and split the Black American community along gendered lines. Thomas's nomination was ultimately confirmed by a margin of 52-48, and he became the second Black American appointed to the U.S. Supreme Court. Clint's book, How the Word is Passed is available now! https://bookshop.org/books/how-the-word-is-passed-a-reckoning-with-the-history-of-slavery-across-america/9780316492935 Sources: Harris, Duchess.
