John Green teaches you about the War of 1812. The War of 1812 was fought between the United States and its former colonial overlord England. John will take you through the causes of the war, tell you a little bit about the fighting itself, and get into just why the US Army couldn't manage to make any progress invading Canada. The upshot: no territory changed hands, and most of the other bones of contention were solved prior to the actual war. Although nothing much changed for the US and England, the Native Americans were the big losers. Tecumseh was killed, and the Indian tribes lost a lot of territory. Watch as John lays it all out for you. [12:41]
