Thomas Mortimer

Sir Thomas Mortimer (c. 1350–1399) was a medieval English soldier and statesman who served briefly in several important administrative and judicial state offices in Ireland and played a part in the opposition to the government of King Richard II. He was an illegitimate member of the Mortimer family, who were one of the leading noble houses of England and Ireland, and he helped to manage the Mortimer lands during the minority of the family heir, his nephew Roger, earl of March. Sir Thomas was also a close associate of the Lords Appellant, the powerful faction of nobles who opposed the administration of King Richard II.

Sir Thomas took part in the Lords Appellants' rebellion in 1387 against the King, and fought at the Battle of Radcot Bridge, during which he killed Sir Thomas Molineux, one of the royal commanders. 10 years later, when the King took his revenge against the rebels, this act led to his conviction for treason. He fled for his life and died in exile. Provided by Wikipedia
