Joan, Princess

Joan, Princess (d. 1237). An illegitimate daughter of King John, Joan was married 1205/6 to Llywelyn ab Iorwerth of Gwynedd, prince of North Wales. Thereafter, she was a wise counsellor to her husband and a peacemaker in the fluid and often belligerent relations between England and Wales. In 1211, when John attacked Wales, Joan pleaded her husband's cause. The following year she warned her father of the hostile plans of his barons. She continued to act as a mediator during the reign of John and of his successor Henry III. In 1226 Pope Honorius III removed the stigma of her illegitimacy. Llywelyn remained indebted to his wife for her support, forgiving her an affair in 1228. He founded a Franciscan monastery to her memory at Llanfaes (Anglesey), where she is buried.

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.
