ʿAbd al-Raḥmān ibn Muḥammad ibn ʿAbd Allāh ibn Muḥammad ibn ʿAbd al-Raḥmān ibn al-Ḥakam al-Rabdī ibn Hishām ibn ʿAbd al-Raḥmān al-Dākhil (; 890–961), or simply ʿAbd al-Raḥmān III, was the Umayyad Emir of Córdoba from 912 to 929, at which point he founded the Caliphate of Córdoba, serving as its first caliph until his death. Abd al-Rahman won the laqab (sobriquet) () in his early 20s when he supported the Maghrawa Berbers in North Africa against Fatimid expansion and later claimed the title of Caliph for himself. His half-century reign was known for its religious tolerance. Life Early years Lineage and appearance Abd al-Rahman was born in Córdoba, on 18 December 890. His year of birth is also given as 889 and 891. He was the grandson of Abdullah ibn Muhammad al-Umawi, seventh independent Umayyad emir of al-Andalus. His parents were Abdullah's son Muhammad and Muzna (or Muzayna), a Christian concubine.

His natural hair was described as being reddish-blond, and he apparently wished to avoid looking like a Visigoth (from many European concubines in his ancestry), desiring to look more like an Umayyad Arab. Due to the fact that each successive Caliph had children almost exclusively with European Christian slave girls, the "Arab" gene was reduced in half, so that the last Umayyad Caliph, Hisham II was around only .09% Arab. Harem youth Muhammad was assassinated by his brother Al-Mutarrif, who had allegedly grown jealous of the favour Muhammad had gained in the eyes of their father Abdallah. Al-Mutarrif had accused Muhammad of plotting with the rebel Umar ibn Hafsun, and Muhammad had been imprisoned. According to some sources, the emir himself was behind Muhammad's fall, as well as Al-Mutarrif's death in 895. Abd al-Rahman spent his youth in his mother's harem. Al-Mutarrif's sister, known as al-Sayyida ("the Lady"), was entrusted with his education. She made sure that Abd
