Thomas le Despenser, 1st Earl of Gloucester

Thomas le Despenser, 1st Earl of Gloucester KG (22 September 1373 – 13 January 1400) was the son of Edward le Despenser, 1st Baron le Despencer, whom he succeeded in 1375.

A supporter of Richard II against Thomas of Woodstock and the Lords Appellant, he was rewarded with an Earldom as Earl of Gloucester in 1397.

However, he supported Henry Bolingbroke on his return to England to become King Henry IV, only to be attainted (deprived of his Earldom because of a capital crime) for his role in the death of Thomas of Woodstock.

He then took part in the Epiphany Rising, a rebellion led by a number of Barons aimed at restoring Richard to the throne by assassinating King Henry IV; this quickly failed when the conspirators were betrayed by Edward of Norwich, 2nd Duke of York to Henry. After fleeing to the western counties, a number of the Epiphany Rising conspirators were captured and killed by mobs of townspeople loyal to the king; Despenser was captured by a mob and beheaded at Bristol on 13 January 1400.

Thomas le Despenser married Constance, daughter of Edmund of Langley, 1st Duke of York. They had issue, of whom:

• Elizabeth le Despenser (died young c. 1398)
• Richard le Despenser, 4th Baron Burghersh (1396–1414)
• Edward le Despenser (b. bef. 1400), died young
• Hugh le Despenser (c. 1400–1401)
• Isabel le Despenser (1393–1439), she married first Richard Beauchamp, 1st Earl of Worcester, she married second his cousin Richard de Beauchamp, 13th Earl of Warwick
