York, Edward, duke of, 1373?–1415, English nobleman; elder son of Edmund of Langley, duke of York. In 1390, Edward was made earl of Rutland, and in 1394 he was created earl of Cork while with his cousin Richard II in Ireland. He acted for the king in the marriage negotiations for the hand of Isabella of France. For his help in the proceedings (1397) against the lords appellant, Richard gave him the lands of the attainted Thomas of Woodstock, duke of Gloucester, and the title duke of Aumâle (Albemarle). He espoused the cause of Henry of Lancaster (Henry IV) against Richard in 1399, but he was accused in Parliament of complicity in the murder of Gloucester and lost his dukedom. He was soon restored to favor, however, and in 1402 he succeeded his father as duke of York. He was appointed (1403) lieutenant of South Wales, but discontent over lack of funds led him to join in an unsuccessful plot to kidnap and make king the captive Edmund de Mortimer, 5th earl of March. York was imprisoned (1405) but was later released and made a privy councilor. Subsequently he served Henry IV in Wales and France and was killed while fighting for Henry V at Agincourt. He was succeeded as duke of York by his nephew, Richard.
