The (Spanish, Portuguese and Galician for "reconquest") is the historical term used to describe the military campaigns that Christian kingdoms waged from the 8th century until 1492, in order to retake the Iberian territories which were lost due to Muslim conquests. The beginning of the Reconquista is traditionally dated to the Battle of Covadonga (718 or 722), in which an Asturian army achieved the first Christian victory over the Arab-Berber forces of the Umayyad Caliphate since the beginning of the military invasion. Its culmination came in 1492 with the fall of the Nasrid kingdom of Granada to the united Spanish Crown of Ferdinand II of Aragon and Isabella I of Castile. In the late 10th century, the Umayyad vizier Almanzor waged a series of military campaigns for 30 years in order to subjugate the northern Christian kingdoms. His armies ravaged the north, even sacking the church of Santiago de Compostela. When the government of Córdoba disintegrated in the early 11th century, a series of petty successor states known as taifas emerged. The northern kingdoms took advantage of this situation and struck deep into al-Andalus; they fostered civil war, intimidated the weakened taifas, and made them pay large tributes (parias) for "protection". After a Muslim resurgence under the Almohads in the 12th century, the great Moorish strongholds in the south fell to Christian forces in the 13th century after the decisive battle of Las Navas de Tolosa (1212)—Córdoba in 1236 and Seville in 1248—leaving only the Muslim enclave of Granada as a tributary state in the south. After the surrender of Granada in January 1492, the entire Iberian peninsula was controlled by Christian rulers. On 30 July 1492, as a result of the Alhambra Decree, all the Jewish community—some 200,000 people—were forcibly expelled. The conquest was followed by a series of edicts (1499–1526) which forced the conversions of Muslims in Spain, who were later expelled from the Iberian peninsula by the decrees of King Philip III in 1609. Beginning in the 19th century, traditional historiography has used the term Reconquista for what was earlier thought of as a restoration of the Visigothic Kingdom over conquered territories. The concept of Reconquista, consolidated in Spanish historiography in the second half of the 19th century, was associated with the development of a Spanish national identity, emphasizing nationalistic and romantic aspects. Its rememoration can still be seen through the festival Moros y Cristianos which was
