General Notes

Constantius III (died 421), Western Roman emperor (421). A general in the
service of the Western emperor Honorius, Constantius became virtual ruler of
the western provinces in 414, when he forced the Visigoths out of Gaul into
Spain. In 417 he married Honorius's sister, Galla Placidia. The next year he
recalled the Visigoths from Spain and established a kingdom for them in
southern Gaul under their ruler Wallia (reigned 415-19). During the last year
of his life, Constantius was officially recognized by Honorius as co-emperor.
