Crash Course: World History — Season 1, Episode 36: Archdukes, Cynicism, and World War I: Crash Course World History #36

Episode synopsis

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.

About Crash Course: World History

Crash Course World History is a video course hosted by John Green that teaches world history from growing the first crops in the First Agricultural Revolution to global textile production in the 2010s. Across the series, it builds skills in identifying and explaining historical developments, analyzing events in broader context, and tracing patterns and connections across time and place—aiming to help viewers become more informed citizens of the world.
