The rulers of Al-Andalus were granted the rank of Emir by the Umayyad Caliph Al-Walid I in Damascus. After the Umayyads were overthrown by the Abbasids, some of their remaining leaders escaped to Spain under the leadership of Abd-ar-rahman I who challenged the Abbasids by declaring Córdoba an independent emirate. Al-Andalus was rife with internal conflict between the Arab Umayyad rulers, the north-African Berbers who had formed the bulk of the invasion force and the Visigoth-Roman Christian population that was a majority for almost the next four centuries.
