1911 Encyclopædia Britannica/Bonifacius
BONIFACIUS (d. 432), the Roman governor of the province of Africa who is generally believed to have invited the Vandals into that province in revenge for the hostile action of Placidia, ruling in behalf of her son the emperor Valentinian III. (428-429). That action is by Procopius attributed to his rival Aëtius, but the earliest authorities speak of a certain Felix, chief minister of Placidia, as the calumniator of Bonifacius. Whether he really invited the Vandals or not, there is no doubt that he soon turned against them and bravely defended the city of Hippo from their attacks. In 432 he returned to Italy, was received into favour by Placidia, and appointed master of the soldiery. Aëtius, however, resented his promotion, the two rivals met, perhaps in single combat, and Bonifacius, though victorious, received a wound from the effects of which he died three months later.
