Bonifatius (or Bonifacius; also known as Count Boniface; died 432) was a Roman general and governor of the diocese of Africa. He campaigned against the Visigoths in Gaul and the Vandals in North Africa. An ally of Galla Placidia, mother and advisor of Valentinian III, Bonifacius engaged in Roman civil wars on her behalf against the generals Felix in 427-429 and Aetius in 432. Although he defeated the latter at the Battle of Rimini, Bonifacius suffered a fatal wound and was succeeded by his son-in-law Sebastianus as patricius of the Western Roman Empire. Biography Early career Bonifatius first appears as a general of Constantius III in 413, where he defeated the Visigoths of Athaulf at Massilia; he allegedly threw a weapon and wounded the Gothic king himself. Later that decade, Bonifatius was known to be a tribunus commanding a Gothic regiment of foederati in North Africa campaigning against the Mauri, and had a friendship with St. Augustine of Hippo with whom he discussed theological matters. In 422 he was likely recalled to the Western court in Ravenna, where he probably married his Gothic wife Pelagia, daughter of Beremudus, and inherited her father's bucellarii. Bonifatius and Castinus then prepared to launch a campaign against the Vandals and Alans in Spain, but Bonifatius' forces never arrived as the two commanders had quarreled constantly since its inception. Galla Placidia sought to prevent Castinus from gaining the position of Stilicho before him, and as a result Castinus attempted to remove Bonifatius from power. Bonifatius retreated to North Africa where he acquired the command of comes africae under dubious circumstances and continued his campaigns against the Mauri tribes. After the death of Emperor Honorius the primicerius notariorum Joannes was elevated to the throne by Castinus in 424, and Bonifatius responded by cutting off the Grain supply from North Africa, showing his support for the Theodosians (Placidia and Theodosius II). Prosper states that Joannes' forces were weakened because they were campaigning against Bonifatius in North Africa, but were unable to depose him like in the campaigns against Gildo and other North African usurpers. After a revolt in Gaul and a military campaign under the eastern generals Ardabur and Aspar sent by Theodosius II, Joannes was overthrown, and Valentinian III, half-nephew of Honorius, was made Western emperor by the magister officiorum Helion. Bonifatius supported him, and resumed the grain shipments to Rome, being rewarded the position of
