John Green teaches you about the Seven Years War, which may have lasted nine years. Or as many as 23. It was a very confusing war. The Seven Years War was a global war, fought on five continents, which is kind of a lot. John focuses on the war as it happened in the Americas, Asia, and Africa. The "great" European powers were the primary combatants, but they fought just about everywhere. Of course, this being a history course, the outcomes of this war still resonate in our lives today. The Seven Years war determined the direction of the British Empire, and led pretty directly to the subject of Episode 28, the American Revolution.
