Berber Revolt
In 740, a Berber Revolt erupted in the Maghreb (North Africa). To put down the rebellion, the Umayyad Caliph Hisham dispatched a large Arab army, composed of regiments ("Junds") of Bilad Ash-Sham, to North Africa. But the great Umayyad army was crushed by the Berber rebels at the Battle of Bagdoura (in Morocco). Heartened by the victories of their North African brethren, the Berbers of al-Andalus quickly raised their own revolt. Berber garrisons in the north of the Iberian Peninsula mutinied, deposed their Arab commanders, and organized a large rebel army to march against the strongholds of Toledo, Cordoba, and Algeciras.
