Exeter, Thomas Beaufort, 1st duke of

Exeter, Thomas Beaufort, 1st duke of (c.1377–1426). The youngest legitimized son of John of Gaunt, Beaufort first served his half-brother Henry IV in the Welsh war and at sea. He was chancellor of England when Prince Henry (later Henry V) controlled the king's council, was created earl of Dorset in 1411 and admiral of England for life in 1412. He participated in Clarence's French expedition and was briefly lieutenant in Gascony. After the capture of Harfleur, he defended it against French attacks and was rewarded by promotion in 1416 to ducal rank. While visiting north country shrines in 1417, he organized the repulse of a Scottish invasion. From 1418 he had a prominent role in the conquest of Normandy; he was governor of Rouen and Paris. He attended the death-bed of Henry V. Back in England, he was a senior member of Henry VI's council in his own last years.

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.
