Flavius Constantius |
Constantius (Latin: Flavius Constantius Augustus) (died 2 September 421), commonly known as Constantius III, was Western Roman Emperor for seven months in 421. A prominent general and politician, he was the power behind the throne for much of the 410s, and in 421 briefly became co-emperor of the Western Empire with Honorius.
Constantius was born in Naissus (modern-day Niš, Serbia) and was probably a career soldier, who reached the rank of magister militum under Honorius.
Constantius avenged the killing of his friend and previous magister militum Stilicho by having the principal instigator of the assassination, Olympius, clubbed to death in 410/11.
In 411 he defeated Gerontius, the general of usurper Maximus, and Constantine III, another usurper, in Arles. Constantine had revolted against Honorius (407), but then he had broken his relationship with general Gerontius, who had proclaimed Maximus Emperor in opposition to both Honorius and Constantine (409). Gerontius had then besieged Constantine in the city of Arles (411), but the arrival of the troops of Constantius from Italy had put him in serious trouble, being at the same time a besieger and a besieged. Gerontius was abandoned by his troops and then killed in Hispania.
