Napoleon, while i understand what you mean about the muslims not necessarliy attacking lands for the purpos of converting them, that did become the end result in most places. Imagiane how much different the world would be today if the Muslims had penitrated deeper into Europe. Now weather or not it would have been for the better or worst is personal opinion, but the world would be totally different. Also Napoleon, you mentioned opressive Byzintine rule, i assume you mean for their collonies? Because unless im mistaken, the people of asia minor and Greece suported their government for the most part.
