bio: |
  By 411 Constantius had reached magister militum under Honorius and crushed the usurper Constantine III that same year. He spent the next years campaigning against barbarian incursions in Hispania and Gaul, clawing back territory the Western Empire had lost. His reward came in 417: marriage to Galla Placidia, Honorius's sister, a public seal of favor. On 8 February 421 Honorius proclaimed him co-emperor. Constantius III died on 2 September 421, seven months into a reign he had earned the hard way.
