Join host John Green to learn about Islam's interactions with politics throughout history and into the present age. Islam has always been tied to political movements; Mohammed was not only a religious leader, but also the leader of an empire. How did this lead to modern movements like ISIS? After all, it is surprising that such a violent fundamentalist movement would come out of what has traditionally been a fairly egalitarian religion with scriptures that value peace. John will discuss these ideas and much more in this episode of Crash Course. [13:27]
