In which John Green teaches you about World War I and how it got started. Crash Course doesn’t usually talk much about dates, but the way that things unfolded in July and August of 1914 are kind of important to understanding the Great War. You’ll learn about Franz Ferdinand, Gavrilo Pincep, the Black Hand, and why the Serbian nationalists wanted to kill the poor Archduke. You’ll also learn who mobilized first and who exactly started the war. Sort of. Actually there’s no good answer to who started the war, but we give it a shot anyway.
While viewing a PowerPoint on Early Civilizations and almost falling asleep during the supporting videos…I clicked on salvation in the form of #crashcourse World History and @johngreenwritesbooks talking about #Mesopotamia. I never expected the money I gave to Crash Course would benefit my own education. #nerdfighter #vlogbrothers
In which John Green teaches you a little bit about drought, which is a natural weather phenomenon, and famine, which is almost always the result of human activity. Throughout human history, when food shortages strike humanity, there was food around. There was just a failure to connect those people with the food that would keep them alive. There are a lot of reasons that food distribution breaks down, and John is going to teach you about them in the context of the late-19th century famines that struck British India.
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 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.
