Humphrey of Lancaster, 1st Duke of Gloucester

Humphrey of Lancaster, Duke of Gloucester was an English prince, soldier, and literary patron. He was "son, brother and uncle of kings", being the fourth and youngest son of Henry IV of England, the brother of Henry V, and the uncle of Henry VI. Gloucester fought in the Hundred Years' War and acted as Lord Protector of England during the minority of his nephew. A controversial figure, he has been characterised as reckless, unprincipled, and fractious, but is also noted for his intellectual activity and for being the first significant English patron of humanism, in the context of the Renaissance.
