Alfonso I, king of Aragón and Navarre

Alfonso I (Alfonso the Battler) ălfŏnˈsō, äl– [key], d. 1134, king of Aragón and Navarre (1104–34), brother and successor of Peter I. The husband of Urraca, queen of Castile, he fought unsuccessfully to extend his authority over her kingdom. He also fought energetically against the Moors, from whom he captured Zaragossa (1118), Calatayud (1120), and many other towns. His raid (1125) into Andalusia bolstered Christian morale, and he encouraged Christians in Muslim lands to settle in his domain. Alfonso was killed in battle against his stepson, Alfonso VII of Castile, and was succeeded by his brother Ramiro II in Aragón and by García IV in Navarre.
