Allectus. Imperial usurper based in Britain, ad 293–6. In 293 the western Roman empire was administered by Maximian and his junior Constantius Chlorus, and the usurper Carausius was operating in Britain and northern Gaul. In 293 Constantius took Boulogne, and Carausius was assassinated by his finance minister Allectus. Allectus himself then became a usurper. Recent archaeological excavations in London, south of St Paul's cathedral, indicate the presence of a palace which dendrochronological studies suggest dates to 293–4; Allectus may well have built it. In 296 Constantius invaded Britain and Allectus was slain in a battle near Silchester.

Learn more about citation styles

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:

  • Most online reference entries and articles do not have page numbers. Therefore, that information is unavailable for most 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.
