Theudebert was the first Frankish king to formally sever his ties to the Byzantine Empire by striking gold coins with his own image on them and calling himself magnus rex (great king) because of his supposed suzerainty over peoples as far away as Pannonia. Theudebert interfered in the Gothic War on the side of the Gepids and Lombards against the Ostrogoths, receiving the provinces of Raetia, Noricum, and part of Veneto.
