who forced the umayyads out of spain by 1492
Umayyad conquest of Hispania Abd ar-Rahman I founded an independent dynasty that survived until the 11th century. That line was succeeded by a variety of short and small emirates (taifas) unable to stop the push of the expansionist northern Christian kingdoms. The Almoravids (1086-1094) and the Almohads (1146-1173) occupied al-Andalus next, and the Marinids in 1269, but that could not prevent the fragmentation of Muslim-ruled territory. The last Muslim emirate, Granada, was defeated by the armies of Castile (successor to Asturias) and Aragon under Isabella and Ferdinand in 1492. The last wave of expulsions from Spain of the native population of Muslim descent took place in 1614.
Iberian Peninsula From the 8th–15th centuries, only the southern part of the Iberian Peninsula was incorporated into the Islamic world and became a center of culture and learning, especially during the Caliphate of Córdoba, which reached its height of its power under the rule of Abd-ar-Rahman III and his successor al-Hakam II.[26] The Muslims, who were initially Arabs and Berbers, included some local converts, the so-called Muladi.[27] The Muslims were referred to by the generic name, Moors[28] The Reconquista gained momentum on c. 718, when the Christian Asturians opposed the Moors, the southern march to push out the Muslims continued for three hundred years[citation needed], so for another four hundred years, only the southern part of the Iberian Peninsula was transformed into a Romance-speaking and Arabic-speaking Muslim land, along with pockets of a large minority of Arabic-speaking Sephardi Jews[citation needed].
