Constans II (died 411) was the son of Western Roman emperor Constantine III, and served as his co-emperor from 409 to 411. Constans was a monk prior to his father being acclaimed emperor by the army in Britain in early 407, an act of rebellion against the ruling emperor Honorius. He was summoned to Gaul, appointed to the position of caesar (heir) and swiftly married so that a dynasty could be founded. In Hispania, Honorius's relatives rose in 408 and expelled Constantine's administration. An army under the generals Constans and Gerontius was sent to deal with this and Constantine's authority was re-established. Honorius acknowledged Constantine as co-emperor in early 409 and Constantine immediately raised Constans to the position of augustus (emperor), theoretically equal in rank to Honorius as well as to Constantine. Later in 409 Gerontius rebelled, proclaimed his client Maximus emperor and incited barbarian groups in Gaul to rise up. Constans was sent to quash the revolt, but was defeated and withdrew to Arles. In 410, Constans was sent to Hispania again. Gerontius had strengthened his army with barbarians and defeated Constans; the latter withdrew north and was defeated again and killed at Vienne early in 411. Gerontius then besieged Constantine in Arles and killed him.
