Considering how far the Umayyad Empire had come into Europe, and their defeat at the Battle of Tours could they have pushed further into Europe? Did Tours really stop their advance or were there other forces that kept them from further conquest?
Their empire was already large, and it's hard to see how their forces could have continued into the Frankish Kingdoms, and maintain a stable country especially considering they just took Iberia. Looking at later times they had revolts in North Africa they were not in solid control, so if they had spread their forces more they could have fallen swifter and lost European territories if there were revolts. So it looks like they hadn't stabilized control but pressed onwards, yet if they didn't then did they stop to stabilize control of the empire or were there other forces at work?
