The Umayyad rulers faced a major Berber Revolt in the early 740s; the uprising originally broke out in North Africa (Tangier) and later spread across the peninsula. Following the Abbasid takeover from the Umayyads and the shift of the economic centre of the Islamic Caliphate from Damascus to Baghdad, the western province of al-Andalus was marginalised and ultimately became politically autonomous as independent emirate in 756, ruled by one of the last surviving Umayyad royals, Abd al-Rahman I. thumb|Islamic rule: al-Andalus 1000 Al-Andalus became a center of culture and learning, especially during the Caliphate of Córdoba. The Caliphate reached the height of its power under the rule of Abd-ar-Rahman III and his successor al-Hakam II, becoming then, in the view of Jaime Vicens Vives, "the most powerful state in Europe". Abd-ar-Rahman III also managed to expand the clout of Al-Andalus across the Strait of Gibraltar, waging war, as well as his successor, against the Fatimid Empire.
