Stained glass panel (1338-1340) depicting Hugh Despenser the Younger who was married to Eleanor the sister of Gilbert de Clare. Hugh Despenser became the favourite of Edward II but was especially disliked by Queen Isabella, and executed when Edward II was deposed in 1326.
Gilbert de Clare (d1295) was the 7th Earl of Gloucester having succeeded to the Earldom in 1262. Gilbert and his brother Thomas first supported Simon de Montfort's rebellion against Henry III, but later changed sides.
Gilbert de Clare, 5th earl of Gloucester, and his father Richard de Clare, were among the 25 barons who pledged to enforce the provisions of the Magna Carta, as a result both were excommunicated by Pope Innocent III.
The stained glass windows in the chancel of Tewkesbury Abbey are all from between 1338 and 1340. They were most probably a gift to the Abbey by Eleanor Despenser (nee de Clare) the wife of Hugh Despenser the Younger. Eleanor is thought to be the person depicted in the panel here.
