YORK, EDWARD, DUKE OF (c. 1373-1415), elder son of the preceding (Edmund of Langley), was created earl of Rutland in 1390. Being a friend of his cousin, Richard II., he became admiral of the fleet, constable of the tower of London and warden of the Cinque Ports. He accompanied the king to Ireland in and was made earl of Cork; arranged Richard's marriage with Isabella, daughter of Charles VI. of France ; and was one of the king's best helpers in the proceedings against the "lords appellant" in 1397. He became constable of England and obtained the lands in Holderness previously belonging to Thomas of Woodstock, duke of Gloucester, together with other estates and the title of duke of Aumerle or Albemarle. He deserted Richard in 1399, but only at the last moment ; and in Henry IV.'s first parliament he was denounced as the murderer of Gloucester. He was reduced
to his former rank as earl of Rutland, and deprived of his recent acquisitions of land. It is uncertain what share Rutland had in thexonspiracy against Henry IV. in Jan. 1400, but he was probably not seriously involved. He served as royal lieutenant in Aqui taine and in Wales, and became duke of York on his father's death in 1402. He was concerned in the scheme, concocted in 1405 by his sister, Constance, for seizing the young earl of March, and his brother Roger Mortimer, and carrying them into Wales, and he was imprisoned in Pevensey castle. Released a few months later, he was restored to the privy council and regained his estates. York led one division of the English army at Agin court, where, on Oct. 25, 1415, he was killed by "much bete and thronggid." He was buried in Fotheringhay church.
