Constantine VI (Byzantine emperor)

Constantine VI, b. c.770, Byzantine emperor (780–97), son and successor of Leo IV. His mother, Irene, was regent until 790, when she was deposed by a military revolt. Constantine recalled her in 792 and made her joint ruler. His subsequent acts of cruelty and his divorce and immediate remarriage (795) alienated his supporters. In 797, Irene deposed her son, had him blinded, and assumed the imperial title. Constantine died in obscurity during the reign (820–29) of Michael II. In his minority the Second Council of Nicaea, which restored icon veneration, took place (787). Constantine fought indecisively against the Bulgarians and the Arabs.

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.
