Constans II (400–411)
Born 400 CE, died 411 CE.
Constans II (died 411) was the son of the Western Roman emperor Constantine III and served as his co-emperor from 409 to 411. When his father rebelled against the ruling emperor Honorius and the army in Britain acclaimed him as emperor in early 407, Constans was a monk. 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 took up arms in 408 and expelled Constantine's administration. An army under Constans and the general Gerontius was sent to deal with this and re-established Constantine's authority. 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 both Honorius and Constantine. Later in 409 Gerontius rebelled, proclaimed his client Maximus emperor and incited barbarian groups which had recently invaded Gaul to rise up. Constans was sent to Hispania to quash the revolt, but suffered a defeat and withdrew to Arelate (modern Arles). In 410, Constans was sent to Hispania with another army.
