(assassinated 26 June 1043
) was made Count of Sobrarbe
, two small Pyrenean
counties, before 1035 by his father, Sancho III of Navarre
. He succeeded to these domains after his father's death in that year and ruled them as vassal of his brother García
until his death.
He is thought to have been ineffectual and unpopular, with vassals defecting to his brother Ramiro during his own life, and one failing to name him in a list of rulers of Ribagorza written within a decade of his death. A late source reports his assassination by one of his own knights, Ramonat de Uasconya, near Lascorz, and he was interred at San Victorián. On his death, García awarded his counties to Ramiro, which initiated several centuries of Aragonese expansionism.
