Abd-ar-Rahman III was the Emir and Caliph of Cordoba (912-961), and a prince of the Ummayad dynasty in the Al-Andalus (Moorish Iberia). He ascended the throne when he was twenty-two and reigned for half a century. His life was so completely identified with the government of the state that he offers less material for biography than his ancestor Abd-ar-Rahman I. Abd-ar-Rahman III was the grandson of his predecessor, Abdullah, one of the Andalusian Umayyads. Wikipedia
