The war between Alfonso of Aragon and his wife Queen Urraca of Castile lasted many years and was accompanied by conspiracies and partisan warfare among the nobles, by scandals in the royal palace, by the papal annulment of the marriage, by plunder of the treasures of the church, by the spoliation and impoverishment of the people. Even the queen’s death in 1126 did not immediately put an end to the war, for the two Alfonsos (her husband, and the son of her first marriage, Alfonso Raymond) now turned their arms against each other. Finally the clergy negotiated a peace. The two kingdoms were separated, a compromise being effected with regard to the disputed districts. Castile with Leon and Galicia formed the territory of Alfonso VII (or VIII,[27] since his stepfather is also counted amongst the Castilian kings); Aragon and Navarre were left to king Alfonso I (1126). The Aragonese now once more turned his arms against the Moslem; the proud name of Batallador, “the fighter,” which his compatriots bestowed on him, may serve as evidence of the strength and energy with which he pushed on the struggle. [He also assumed the title of emperor.] It has been mentioned that by the conquest of Huesca, his predecessor Pedro had confirmed and consolidated the kingdom of Aragon. Ten years after his death, Tudela on the Ebro was won, and formed an important base for further conquest; but it was only when Alfonso, supported by the knights from the southern kingdom, had conquered the Saracens in several sharp encounters and finally, after a siege of seven months, had compelled the surrender of the city of Saragossa, 1118, the bulwark of the Arab rule in the northeast, that the kingdom of Aragon was able to proceed with its political development. Saragossa, so long the seat of a Mohammedan emir, became Alfonso’s capital. The principal mosque served henceforth for the worship of the Saviour. The knights and nobles who had stood bravely by the side of the king, as well as the soldiers who had gathered to his banner from beyond the Pyrenees, were richly rewarded. [Sidenote: [1118-1150 A.D.]] The Moslems were deeply affected by the loss of Saragossa, the result of their own want of unity; that they might not be entirely driven from the territory of the Ebro they nerved themselves to a general resistance. There was a series of sanguinary conflicts on the Segre and Ebro, and then under their brave commander Yahya ben Gania they won by stratagem the battle of Fraga, July, 1134, with which Alfonso ended his heroic life. His efforts had undermined his strength, and grief at this severe defeat did the rest. He sank on a bed of sickness from which he never rose again.[28]
