Hi there, I'm John Green, this is Crash Course World History, and today we're going to talk about Islam, which, like Christianity and Judaism, grew up on the east coast of the Mediterranean. But unlike Christianity and Judaism, it's not terribly well understood in the West. For instance, you probably know what this is and what this is. You probably don't know what that is. Google it. Mr. Green, Mr. Green, why do you think people know so little about Islamic history? Did you just ask an interesting, non-annoying question me from the past?
