Spain with an enormous force in order to extinguish the Christian rule there, but fell in a battle at Santarem against Alfonso I. of Portugal. His son Jacob avenged the disaster by the bloody battle of Alarcos in A.D. 1195, where 30,000 Castilians were left upon the field. When, notwithstanding the overthrow, the Christians a few years later endeavoured to retrieve their loss, Jacob’s successor Mohammed descended upon Spain with half a million fanatical followers. The critical hour for Spain had now arrived. The Christians had won time to come to agreement among themselves. They fought with unexampled heroism on the plain of Tolosa in A.D. 1212 under Alfonso VIII. of Castile. The battlefield was strewn with more than 200,000 bodies of the African fanatics. It was the death-knell of the rule of the Almohad in Spain. Notwithstanding the dissensions and hostilities that immediately broke out among the Christian princes, they conquered within twenty-five years the whole of Andalusia. The work of conquest was carried out mostly by Ferdinand III., the saint of Castile, A.D. 1217-1254, and Jacob I., the conqueror of Arragon, A.D. 1213-1276. Only in the southernmost district of Spain a remnant of the Moslem rule survived in the kingdom of Granada, founded in A.D. 1238 by the emir Mohammed Aben Alamar. Here for a time the glories of Arabic culture were revived in such a way as seemed like a magical restoration of the day of the Ommaiades. In consequence of the marriage in A.D. 1469 of Ferdinand of Arragon, who died in A.D. 1516, with Isabella of Castile, these two most important Christian empires were united. Soon afterwards the empire of Granada came to an end. On 2nd January, A.D. 1492, after an ignominious capitulation, the last khalif, Abu Abdilehi Boabdil, was driven out of the fair (Granada), and a few moments later the Castilian banner waved from the highest tower of the proud Alhambra. The pope bestowed upon the royal pair the title of Catholic monarchs. The Moors who refused to submit to baptism were expelled, but even the baptized, the so-called Moriscoes, proved so dangerous an element in the state that Philip III., in A.D. 1609, ordered them to be all banished from his realm. They sought refuge mostly in Africa, and there went over openly again to Mohammedanism, which they had never at heart rejected.[270]
