Ferdinand and Isabella completed the Reconquista with a war against the Emirate of Granada that started in 1482 and ended with Granada's surrender on 2 January 1492. The Moors in Castile previously numbered "half a million within the realm". By 1492 some 100,000 had died or been enslaved, 200,000 had emigrated, and 200,000 remained in Castile. Many of the Muslim elite, including Granada's former Emir Muhammad XII, who had been given the area of the Alpujarras mountains as a principality, found life under Christian rule intolerable and emigrated to Tlemcen in North Africa.
