House of York

The House of York was a cadet branch of the English royal House of Plantagenet. Three of its members became kings of England in the late 15th century. The House of York descended in the male line from Edmund of Langley, 1st Duke of York, the fourth surviving son of Edward III. In time, it also represented Edward III's senior line, when an heir of York married the heiress-descendant of Lionel, Duke of Clarence, Edward III's second surviving son. It is based on these descents that they claimed the English crown. Compared with its rival, the House of Lancaster, it had a superior claim to the throne of England according to cognatic primogeniture, but an inferior claim according to agnatic primogeniture. The reign of this dynasty ended with the death of Richard III of England at the Battle of Bosworth Field in 1485. It became extinct in the male line with the death of Edward Plantagenet, 17th Earl of Warwick, in 1499.

Edmund's first marriage was to Isabella of Castile, daughter of Peter of Castile and María de Padilla, and sister of Constance of Castile, second wife of Edmund's older brother John of Gaunt. Through this marriage Edmund had two sons, Edward, 2nd duke of York and the younger Richard of Conisburgh. His second marriage was to Joan Holland, whose sister Alianore Holland was mother to Anne Mortimer, the great-great-granddaughter of Edward III via Lionel of Antwerp, 1st Duke of Clarence, second surviving son of Edward III, and the elder brother of John of Gaunt. Richard of Conisburgh married Anne Mortimer, the marriage producing two children, Isabel of Cambridge and Richard of York, 3rd Duke of York. It was through Anne Mortimer's lineage that the Yorkists derived their main claim to the throne.
