Norfolk, Thomas Howard, 2d duke of, 1443–1524, English nobleman, son of John Howard, 1st duke of Norfolk. He fought at the battle of Bosworth (1485) in which his father was killed. He himself was captured, attainted, and placed in the Tower of London. He was released (1489) by Henry VII and restored to the earldom of Surrey, which he had received in 1483, but not to the dukedom of Norfolk. He was entrusted by Henry VII with the care of the northern borders and in 1501 was made lord treasurer. Recognized as the leading general in England, he commanded the army that defeated (1513) the Scots at Flodden and was created (1514) duke of Norfolk. Although an influential member of Henry VIII's privy council, he was gradually forced to relinquish much of his power to the ascending Thomas Wolsey. He served as guardian of the realm during Henry's absence in 1520. In 1521, acting as lord high steward, he was compelled to sentence his friend Edward Stafford, 3d duke of Buckingham, to death.
