William de la Pole, 1st Duke of Suffolk,, nicknamed Jackanapes, was an English magnate, statesman and military commander during the Hundred Years' War. He became a favourite of the weak king Henry VI of England, and consequently a leading figure in the English government where he became associated with many of the royal government's failures of the time, particularly on the war in France. Suffolk also appears prominently in Shakespeare's Henry VI, parts 1 and 2.
