هشام بن عبد الملك
Abd al-Rahman I, more fully Abd al-Rahman ibn Mu'awiya ibn Hisham ibn Abd al-Malik ibn Marwan (731–788) was the founder of the Arab dynasty that ruled the greater part of Iberia for nearly three centuries (including the succeeding Caliphate of Córdoba). Abd al-Rahman was a member of the Umayyad dynasty in Damascus, and his establishment of a government in Iberia represented a break with the Abbasids, who had overthrown the Umayyads in 750.
