While Almamon lived, Alphonso IV. never forgot his obligations to his benefactor. He maintained peace with him, aided him in his campaigns against the King of Seville, and even entered into a treaty with Hacchem, the son and successor of his ally. But, after a brief reign, Hacchem left the throne of Toledo to his youthful brother Jahiah. That prince oppressed the Christians, who were very numerous in his city; and they secretly implored Alphonso to make war upon Jahiah. The memory of Almamon long caused the Spanish monarch to hesitate in relation to this subject. Gratitude impelled him not to listen to the suggestions of ambition and the prayers of his countrymen; but the arguments of gratitude proved the least strong, and Alphonso encamped before Toledo. After a long and celebrated siege, to which several French and other foreign warriors eagerly hastened, Toledo finally capitulated, A.D. 1085, Heg. 478. The conqueror allowed the sons of Almamon {89} to go and reign at Valencia, and engaged by an oath to preserve the mosques from destruction. He could not, however, prevent the Christians from speedily violating this promise. Such was the end of the Moorish kingdom of Toledo. This ancient capital of the Goths had belonged to the Arabs three hundred and eighty-two years. Several other less important cities now submitted to the Christian yoke. The kings of Aragon and Navarre, and the Count of Barcelona, incessantly harassed and besieged the petty Mussulman princes who still remained in the north of Spain. The attacks of the kings of Castile and Leon afforded sufficient occupation for those of the south, effectually to prevent their rendering any assistance to their brethren. Above all, the Cid, the famous Cid, flew from one part of Spain to another, at the head of the invincible band with whom his fame had surrounded him, everywhere achieving victories for the Christians, and even lending the aid of his arms to the Moors when they were internally divided, but always securing success to the party he favoured. This hero, one of the most truly admirable of those whom history has celebrated, since in his {90} character were united the most exalted virtue and the highest qualities of the soldier; this simple Castilian cavalier, upon whom his reputation alone bestowed the control of armies, became master of several cities, assisted the King of Aragon to seize upon Huesca, and conquered the kingdom of Valencia without any other assistance than that of his men-at-arms. Equal in power with his sovereign, of whose treatment he frequently had reason to complain, and envied and persecuted by the jealous courtiers, the Cid never forgot for a moment that he was the subject of the King of Castile. Banished from court, and even exiled from his estates, he hastened, with his brave companions, to attack and conquer the Moors, and to send those of them whom he vanquished to render homage to the king who had deprived him of his rights.
