He was succeeded by two sons who ruled jointly, but on the death of the survivor of the two, sometime between 1005 and 1030, Viguera was reabsorbed into the main Pamplona kingdom.
Its territory encompassed the valleys of the Iregua and Leza rivers in the heartland of the present-day Rioja.
[3] In the year 918 Ordoño II of León and Sancho I of Pamplona invaded Viguera to clear out the Banu Qasi dynasty from the land.
After the insistence of his second wife, Teresa Ramírez of León, García I willed Viguera to his first son with her, Ramiro Garcés.
After the death of García I, his son Sancho II, acting as King of Pamplona, recognised his half-brother's rights over Viguera.
