Riothamus

The late 5th century Brittonic leader Riothamus received correspondence from the eminent Roman jurist Sidonius Apollinaris and was called "King of the Britons" by Jordanes. Some suggest that he was a Breton, though others believe that he was from Britain, pointing to the passage that he arrived in the land of the Biturges "by way of Ocean", which would hardly have been efficient or required for a Breton. Both historians describe Riothamus's losing battle against King Euric of the Visigoths at Déols around the year 470.

In response to a plea from the Roman Emperor Anthemius, Riothamus had led twelve thousand men to establish a military presence in Bourges in central Gaul, but was betrayed by Arvandus, the Praetorian Prefect of Gaul, and subsequently ambushed by Euric's army. After a long battle, the Armorican survivors escaped to Avallon in Burgundy, after which they are lost to history. According to Breton king-lists, Riotham survived and reigned as Prince of Domnonia until his death sometime between 500 and 520, though this may have been a different person.
