In the life-time of his father (9th Richard II.), he was joined with Thomas Clifford, son of Lord Clifford, in the governorship of the city and castle of Carlisle, and was appointed a commissionership for the guardianship of the West Marches. In three years after this he succeeded to the title, and in two years subsequently he was one of the commissioners appointed to treat with the Kings of France and Scotland, touching a truce made by them with the King of England. In the 21st Richard II., he was made constable of the Tower of London, and shortly afterwards advanced in full parliament to the dignity of Earl of Westmoreland. His lordship was the privy council to King Richard, and had much favour from that monarch, yet he was one of the most active in raising Henry, of Lancaster, to the throne, as Henry IV., and was rewarded by the new king in the first year of his reign, with a grant of the county and honour of Richmond for his life, and with the great office of Earl Marshal of England. Soon after this he stoutly resisted the Earl of Northumberland in his rebellion, and forced the Percies, who had advanced as far as Durham, to fall back upon Prudhoe, when the battle of Shrewsbury ensued, in which the gallant Hotspur sustained so signal a defeat, and closed his impetuous career. The earl was afterwards governor of the town and castle of Carlisle, warden of the West Marches towards Scotland, and governor of Roxborough. He was also a knight of the Garter.
