Magnentius

Magnentius, a usurping emperor 350–3, was at his elevation an army commander in Britain. He was probably born at Amiens. In 350 he was proclaimed emperor by the Gallic cabal which deposed Constans. He crossed to the continent and was defeated by Constantius II at the costly battle of Mursa in Pannonia in 351. It was two years before Constantius could press home his advantage and kill Magnentius at the battle of Mons Seleucus in Gaul. After Magnentius' death, vicious reprisals were visited on his supporters in Britain.

Citation styles

Encyclopedia.com 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, Encyclopedia.com cannot guarantee each citation it generates. Therefore, it’s best to use Encyclopedia.com 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:

Notes:
  • Most online reference entries and articles do not have page numbers. Therefore, that information is unavailable for most Encyclopedia.com content. However, the date of retrieval is often important. Refer to each style’s convention regarding the best way to format page numbers and retrieval dates.
  • In addition to the MLA, Chicago, and APA styles, your school, university, publication, or institution may have its own requirements for citations. Therefore, be sure to refer to those guidelines when editing your bibliography or works cited list.
