I want to know the answer to the following question:
What dynasty ruled Egypt in this period?
All the background I'm provided with is that "The defeat of Muslim forces at the Battle of Poitiers in 732 led to the reconquest of southern France by the Franks, but the main reason for the halt of Islamic growth in Europe was the overthrow of the Umayyad dynasty and its replacement by the Abbasid dynasty.". Is that enough to answer the question?
