Abd-ar-Rahman III
During the 9th century the Berbers returned to North Africa in the aftermath of revolts. Many governors of large cities distant from the capital, Córdoba, had planned to establish their independence. Then, in 929, the Emir of Córdoba (Abd-ar-Rahman III), the leader of the Umayyad dynasty, declared himself Caliph, independent from the Abbasids in Baghdad. He took all the military, religious, and political power and reorganised the army and the bureaucracy.
