Abbasid power dwindled during the 10th century, when the empire disintegrated and was divided among a number of vassals. Most of the new rulers acknowledged the caliph as their nominal sovereign, a situation which continued until the Mongol destruction of the Abbasid Caliphate in 1258.In 955 Sayf al-Dawla, the Hamdanid prince of Aleppo, defeated the nomads near the city, and built a kasbah (fortress) in response to campaigns by the Byzantine emperors Nikephoros II Phokas and John I Tzimiskes.
