He is a spiritual figure. He has revelations, but he is also the founder of an empire. He also governs. He is also a military and political figure. And so perhaps for the first time in history on this scale, you have the combination of religious zeal, of spiritual belief, of faith, combined with governance, combined with the desire to create an empire. In terms of empire, the only thing that might be comparable in terms of the vastness and the speed in which it happens is the Mongol Empire. The Mongols are an example of people who are fragmented initially, tribal, unified by Genghis Khan, and through that unification, were able to spread incredibly rapidly and take on some long, historic, and possibly declining empires.
