Galla Placidia (găl´ə pləsĬd´ēə), c.388–450, Roman empress of the West, daughter of Theodosius I. Captured by Alaric I in the course of his Italian campaign, she was held by the Visigoths as a hostage and married (414) Alaric's successor Ataulf. After the murder (415) of Ataulf she was at first ill-treated but was returned in 416 to her brother Honorius. In 417 she married the general Constantius; shortly before his death he was made (421) coemperor as Constantius III. In 423 she quarreled with Honorius and fled to the court of Theodosius II; after the death of Honorius she became regent for her son Valentinian III, whom Theodosius placed on the throne after overthrowing (425) the usurper John. She had great personal influence over her son, but she was forced to leave the government largely in the hands of Aetius.

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:

- 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.
