 Arthur Tudor ( 20 September 1486 – 2 April 1502 ) was Prince of Wales , Earl of Chester and Duke of Cornwall . As the eldest son and heir apparent of Henry VII of England , Arthur was viewed by contemporaries as the great hope of the newly established House of Tudor . His mother , Elizabeth of York , was the daughter of Edward IV , and his birth cemented the union between the House of Tudor and the House of York .
