 Henry Tudor declared himself king, took Elizabeth of York, eldest child of Edward IV, as his wife, symbolically uniting the surviving houses of York and Lancaster, and acceded to the throne as Henry VII, founder of the Tudor dynasty which reigned until 1603.The de la Pole family were sometimes suggested as heirs to the Yorkist cause, but Henry Tudor and his son Henry VIII of England efficiently suppressed all such opposition.Another Yorkist branch descends from George Plantagenet, 1st Duke of Clarence, and younger brother of Edward IV.
