Prince of Wales (1343–76), the eldest son of Edward III. He was an outstanding example of the chivalric ideal, a military leader who helped restore national pride to the English by a series of victories in the Hundred Years War. He commanded part of his father’s army at Crécy (1346), and in 1356 won the Battle of Poitiers, capturing John II. In 1367 he restored King Pedro to the throne of Castile, but the campaign in Spain ruined his health. By his love match to Joan, the ‘Fair Maid of Kent’, he left one son, the future Richard II.
