Suppose the Moors win at Tours and go on to conquer Europe up to the Rhine and beyond. What does their culture look like? How does Islam interact with the existing cultures and legends? Would Christianity persist in some form, or possibly syncretized into a branch of Islam that places more emphasis on Jesus? 'Firanji' Islam, perhaps? How about Roman and Norse legends -how would these interact and be Islamicized? What about the minor Christian sects (were the Cathars still around?), would they be absorbed? Would the government take on a more 'European' form, eventually?
