About John Deydras

John Deydras was an English clerk (position).

John Deydras (died 1318), also known as John of Powderham, was a pretender to the English throne during the reign of Edward II. He was executed by hanging and his body was burnt.

Background

By 1318, Edward II of England was increasingly unpopular in England as a result of his style of government and his defeats while fighting Robert the Bruce of Scotland. Opposition was growing to his rule, when a young clerk in Oxford, John Deydras, also known as John of Powderham, issued claims that he was in fact the rightful heir to the throne. which had bitten off his ear.

Legacy

Today, Deydras is believed to have been mentally ill; his story is not believed to have been true. Modern historians cite the case of Deydras as an example of the growing unhappiness with Edward II's rule during the period, and the protracted case appears to have deeply affected Isabella of France, Edward's wife, who felt humiliated by the event.
