 In addition to repulsing several attacks from the Emir of Córdoba, Sancho I crushed the neighboring Banu Qasi and thus expanded Pamplona to the upper Ebro River valley, as well as incorporating the previously-autonomous County of Aragon into the realm.Following the death of Sancho in 925, his brother Jimeno Garcés maintained a position of strength, intervening in the politics of neighboring Christian and Muslim states.His death left the crown to his nephew, Sancho's son García Sánchez I, who was still a child.
