Sancho III of Pamplona

Sancho III Garcés, called the Great (born between 992 and 996, died 1035), inherited Pamplona as a child in 1004 and, through marriage and conquest, built the largest Christian power in Spain.

He added Sobrarbe in 1015 and Ribagorza in 1018, occupied Castile after the murder of its count in 1027 and gave it to his son Ferdinand, and in 1034 captured León.

A patron of Cluny who fostered the pilgrim road to Santiago, he divided his realms among his sons on his death in 1035, laying the foundations for the later kingdoms of Aragon and Castile.
