Jovinus

Jovinus, a prominent Gallo-Roman senator, rose to prominence as a usurper claiming the title of Roman Emperor from four hundred eleven to four hundred thirteen AD. His ascent to power came after the downfall of Constantine III, when he was proclaimed emperor in Mainz, backed by influential figures such as Gundahar, the king of the Burgundians, and Goar, the king of the Alans.

During his brief reign, Jovinus managed to maintain his position in Gaul for two years, a period during which he issued coinage depicting himself adorned with the imperial diadem. His rule was supported by several local Gallo-Roman nobles who had survived the political upheaval following Constantine's defeat.

However, Jovinus' reign was marred by conflict. The Visigoths, led by Ataulf, initially appeared to ally with him but soon turned against him after a series of betrayals. Jovinus' decision to elevate his brother Sebastianus as co-emperor without consulting Ataulf led to a significant rift, prompting Ataulf to ally with Honorius against Jovinus.

The ensuing battle resulted in the defeat of Jovinus' forces, the execution of Sebastianus, and Jovinus' desperate flight. Ultimately, he was captured in Valentia and taken to Narbo, where he met his end at the hands of Claudius Postumus Dardanus, the loyal praetorian prefect to Honorius. The heads of Jovinus and Sebastianus were later displayed as a grim reminder of their failed rebellion.
