Edward, Prince of Wales (1473-1484). Edward of Middleham, Prince of Wales, KG and Earl of Chester, Duke of Cornwall, 1st Earl of Salisbury (December 1473 - 9 April 1484), was the only child of King Richard III of England and his queen consort, Anne Neville. He was Richard's only legitimate child and died aged 10. In 1485, Richard was killed during the Wars of the Roses, thus ending that conflict and the throne of England reverted to Richard III's successor, Henry Tudor, a descendant of Edward III of England through his mother, Lady Margaret Beaufort.
