Also known as Thomas of Woodstock, he was brother of John of Gaunt and uncle of Richard II. He was twenty-two when his nephew succeeded, and during Richard's minority he prospered, receiving the Garter in 1380 and a dukedom in 1385. The following year he led the attack upon Richard's favourite, Michael de la Pole, earl of Suffolk, who was impeached, and in 1387 took up arms against another favourite, the earl of Oxford. For a few months he exercised great power, but Richard reasserted himself, and the rapprochement was always insecure. In the summer of 1397, the king carried out a coup, arresting Gloucester in person at his own mansion. He was taken to Calais, forced to confess, and then either strangled or smothered.
