Thomas of Lancaster

Thomas of Lancaster (c.1278–1322) was one of the most powerful magnates during the reign of Edward II and a thorn in the side of the king. He was the son of Edmund Crouchback, a younger son of Henry III and was therefore first cousin to Edward II. Succeeding to the earldom of Lancaster in 1296, he served against the Scots during Edward I's reign. But as soon as his cousin succeeded, Thomas moved into opposition. He took an active part against the royal favourite Gaveston, was one of the Ordainers appointed to supervise the young king, and brought about Gaveston's execution in 1312. He refused to serve in the Bannockburn campaign of 1314 and profited from the king's humiliation to increase his own influence. In 1316 he was appointed chief counsellor and in 1318 he and Edward were briefly reconciled at the treaty of Leake, taking part in the unsuccessful campaign against the Scots in 1319. But by 1321 he was once more at odds with the king over the Despensers, whom he forced into exile. In 1322 he was captured at Boroughbridge and executed at Pontefract in the king's presence. Though the experiment with conciliar government recalls de Montfort's career under Henry III, Thomas's activities seem to have been purely factious. Surprisingly a cult grew up at Pontefract and miracles were said to have been performed. The earldom passed to his younger brother, whose great-grandson took the throne as Henry IV.

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:
