Muhammad XI, d. 1538, last sultan of Granada in Spain (1482–92); also called Boabdil by the Spanish. He seized the throne from his father and thus plunged Granada into civil war at the time the Castilians were beginning their attack on the kingdom. As the Christians overran western Granada, Muhammad secretly promised (1487) them that he would surrender the city of Granada in return for some cities held by the rival Granadian party. However, he repudiated the agreement, and in Apr., 1491, the Castilians laid siege to Granada. After valiant resistance, Muhammad surrendered in Jan., 1492, and fled to Morocco. His surrender marked the end of Moorish rule in Spain, and he is the subject of a number of romantic legends.
