British Usurper

Constantine III was a man of humble origin and a common soldier. He was proclaimed Emperor by the Roman legions stationed at the time in Britain during 407 AD and subsequently raised his son Constans to the rank of joint Emperor. Constantine immediately crossed over the channel to Gaul where he quickly established himself alongside the barbarian invaders of the province. In 408 AD, Constantine expanded his territory to include Spain. In 409, however, Spain was overrun by the Vandals, Alani, and Suevi, primarily due to treachery on the part of one of his own generals named Gerontius. Constantine was eventually captured by Constantius III, a leading general under Emperor Honorius. Constantine III was ultimately sent to Italy in 411 AD where he was put to death.
