The Muslims had no chance of taking over that stuff anyway. This isn't Civilization, where unlimited expansion isn't particularly difficult. It's having to deal with a Visigothic/early Hispanic insurrection in Asturias, trying to send large numbers of troops across the Pyrenees and maintaining them, actually defeating a primarily heavy force with light units used as shock cavalry (a really, really dumb idea) tactically, conquering the area, eliminating those annoying Christian feudals (who this time are not riven by religious troubles as were the Visigoths, i.e. the leftover Arians from the conversion a century prior), co-opting the populace, and actually holding on to the place.Stopped Muslim expansion into Europe. I think a Muslim western Europe, if not disastrous, is at least a verydifferent world.
Unlikely.
Very true; by Frankish, of course, perhaps replace "Carolingian", but yeah, Tours is more important for creating the precondition for the rise of Charlemagne.Actually, Tours is more important as consolidating Frankish power in Europe.
