Jovinus, having proclaimed himself the successor of the late usurper Constantine III at Mainz with the support of some Alans and Burgundians, also receives strong supports from a number of local Gallo-Roman nobles who had survived Constantine's defeat.

He mints coins, showing him wearing the imperial diadem, in Trier, Lyon and Arles.

The late Alaric's brother-in-law and successor Ataulf, using Galla Placidia, sister to Emperor Honorius, as a bargaining chip, had allied his Visigoths with Rome and led his people north to suppress the revolts in Gaul and Spain.

Jovinus acclaims his brother Sebastianus as augustus.
