Lupus ruled the Duchy of Spoleto from 745 to 752 relatively independent of royal authority in the reigns following the that of Liutprand.
He made many donations to the Abbey of Farfa and had a close relationship with Abbot Fulcoald. On his death, the duchy was probably seized by Aistulf and then granted to one Unnolf for a brief spell.
