Humphrey Stafford, 1st Duke of Buckingham, English commander and politician, Lord High Constable of England (born 1402)

Humphrey Stafford, 1st Duke of Buckingham, 6th Earl of Stafford, 7th Baron Stafford of Stafford Castle in Staffordshire, was an English nobleman and a military commander in the Hundred Years' War and the Wars of the Roses. Through his mother he was of royal descent from King Edward III, his great-grandfather, while from his father, he inherited, at an early age, the earldom of Stafford. By his marriage to a daughter of Ralph, Earl of Westmorland, Humphrey was related to the powerful Neville family and to many of the leading aristocratic houses of the time. He joined the English campaign in France with King Henry V in 1420. Following Henry V's death two years later he became a councillor for the new king, the nine-month-old Henry VI. Stafford acted as a peacemaker during the factional politics of the 1430s, when Humphrey, Duke of Gloucester, vied with Cardinal Beaufort for political supremacy. Stafford also took part in the eventual arrest of Gloucester in 1447.
