Boniface (bŏn´əfās), d. 432, Roman general. He defended (413) Marseilles against the Visigoths under Ataulf. Having supported Galla Placidia in her struggle with her brother, Emperor Honorius, Boniface fled to Africa in 422. There, as semi-independent governor, he supported (424) Valentinian III against the usurper John and was rewarded with the title count of Africa. Recalled in 427, he rebelled; a civil war between Africa and the imperial government began. This struggle prepared the way for the invasion (429) of Africa by the Vandals under Gaiseric. A truce was arranged between Africa and Rome, and Boniface attacked the Vandals. He was defeated and besieged (430) at Hippo; during the siege his good friend St. Augustine died. Beaten again in 431, Boniface was recalled to Italy by Placidia to assist her against the general Aetius. He defeated (432) Aetius but died of a wound received in the battle. The historian Procopius, without convincing evidence, held Boniface responsible for inviting the Vandals into Africa.

Citation styles gives you the ability to cite reference entries and articles according to common styles from the Modern Language Association (MLA), The Chicago Manual of Style, and the American Psychological Association (APA).

Within the “Cite this article” tool, pick a style to see how all available information looks when formatted according to that style. Then, copy and paste the text into your bibliography or works cited list.

Because each style has its own formatting nuances that evolve over time and not all information is available for every reference entry or article, cannot guarantee each citation it generates. Therefore, it’s best to use citations as a starting point before checking the style against your school or publication’s requirements and the most-recent information available at these sites:
