Son of Constantine III
Constans was the the son of Constantine III, the usurper of Britian. He was raised to the rank of Augustus by his father sometime during 408 AD at the time of the invasion of Spain, which he led. Constans came under siege while in Vienne during 411 AD by Gerontius who succeeded in capturing the young emperor and subsequently put him to death.
The coinage of this young co-emperor is extremely rare. No denominations are known other than a typical reduced siliqua of the period.
