Definition of Henry iii of england

Henry III (1 October 1207 –  16 November 1272) was the son and successor of John "Lackland" as King of England, reigning for fifty-six years from 1216 to his death. Medieval English monarchs did not use numbers after their names, and his contemporaries knew him as Henry of Winchester. He was the first child king in England since the Norman Conquest. Despite his long reign, his personal accomplishments were slim and he was a political and military failure. England, however, prospered during his century and his greatest monument is Westminster, which he made the seat of his government and where he expanded the abbey as a shrine to Edward the Confessor.
