Yet, aware of the Cid's value, Alfonso seems to have concealed his resentment for some time, and even endeavored to win the affection of his great subject by allying him in marriage with one of the royal family. Rodrigo's wife was now dead, and he consented to marry the princess proposed to him, whose name was also Ximena. The marriage took place in 1074. It had not the effect, however, of uniting the king and the Cid. After having achieved a brilliant success over the Arabs of Granada, who were at war with two other Moslem states in alliance with Castile, and having signalized his humanity by releasing all his prisoners, the great Campeador was disgraced and banished by his ungrateful master. At the court of the Emir of Saragossa the exile found a ready welcome, and was appointed to a high post in the government of the kingdom. He did not bear arms against his own sovereign, but headed the Arabs in several battles with the Christians of Aragon and other states. The invasion of a Moorish host in Spain, under the eminent Caliph Jusef Ben Taxfin, chief of the Almoravides and conqueror of Morocco; the rapid subjugation of the independent Emirs, and the defeat of Alfonso's army at the battle of Zalaka, in 1087, recalled the Castilians to a sense of Rodrigo's worth. He was invited to return by Alfonso, and with great generosity consented, bringing with him a large body of men raised by his own exertion and cost. For two years he made his name terrible to the Moors, as the great Christian champion. But even this fame was not sufficient to secure his influence at court, and about the year 1090 he was once more banished, and his estates were seized. He appears from this time to have commenced a life of adventurous and independent warfare with the Moors. He besieged Alcocer, a strong Moorish fortress on the borders of Aragon, and finally took it. With a band of determined warriors of his own stamp he ravaged, consumed, and spoiled all the Moslem territories which he invaded, making a castle on a rock in Ternel his chief stronghold, and thence sallying out in forays. The place has been ever since called the Rock of the Cid.
