The victors desecrated the tombs of the Umayyads in Syria, sparing only that of Umar II, and most of the remaining members of the Umayyad family were tracked down and killed. When Abbasids declared amnesty for members of the Umayyad family, eighty gathered to receive pardons, and all were massacred. One grandson of Hisham, Abd al-Rahman I, survived, escaped across North Africa, and established an emirate in Moorish Iberia (Al-Andalus). In a claim unrecognized outside of al-Andalus, he maintained that the Umayyad Caliphate, the true, authentic caliphate, more legitimate than the Abbasids, was continued through him in Córdoba. It was to survive for centuries.
