Constantius III (Flavius Constantius) was Roman emperor of the West in 421, from 8 February until his death on 2 September. That same year, he was sent to suppress the revolt of Constantine III, a Roman general who declared himself emperor. Revolt of Constantine III[edit] Despite Constantius' assurances that Constantine would be able to safely retire to a clerical office, Constantius had him imprisoned, and further had him beheaded during his return to Ravenna, in either August or September 411.[3] Honorius' remaining rivals were soon defeated, with Gerontius committing suicide in Hispania,[6] and Jovinus being defeated by Athaulf, king of the Visigoths.[5] Despite this, Honorius was unable to regain control of Britain, nor was any Roman after him.[7] Constantius reigned as co-emperor only seven months before dying on 2 September 421, in Ravenna.[1][13] Constantius was succeeded by Honorius, who ruled alone until his death in 423, whereupon Valentinian III, Constantius' son, assumed the throne, with Galla Placidia serving as regent.[14] ./cache/en-wikipedia-org-2926.html ./txt/en-wikipedia-org-2926.txt
