Kingdom of Aragon
The Muslim invaders were not very numerous, being mainly Berbers, but also, in later waves, Arabs and Syrians. Those established in the Ebro valley were mostly Arabs, divided between Qaysids and Kalbis, Arabs from the north and south. The majority of the Muslim population in the area at the time of the reconquest were Muladis, Christians converted to Islam. Those Christians who did not convert, called Mozarabs, were tolerated by the Muslim rulers in exchange for the payment of special taxes.
