He was either a son of García I or of Centule, a brother of Sancho I. Lupo was a Gascon rebel against the authority of Pepin in Aquitaine.
In 818, the death of García left a power vacuum in Gascony which Lupo attempted to fill.
Pepin responded quickly, however, and entered Gascony, emanating a diploma at Castillon-sur-Dordogne the next year.
He formally deposed Lupo and sent Berengar of Toulouse and Guerin of Auvergne into the region to dislodge him from power.
