The muwallad, Umar ibn Hafsun, begins a revolt against the Umayyads. From his refuge in the castle of Bobastro, he steadily attracts the support of disaffected muwallads and Mozarabs, and takes control of numerous towns and castles. The Umayyad rulers begin employing mercenary soldiers, including Christian Castilians, Muslim Berbers and Slavs, to counter any threats to their power.
