This new history is the first to tell the story of Magna Carta âthrough the agesâ. No other general work traces its continuing importance in Englandâs political consciousness. Â Many books have examined the circumstances surrounding King Johnâs grant of Magna Carta in 1215. Very few trace the Charterâs legacy to subsequent centuries and even fewer look at the fate of the physical document. Â Turner also underlines its great influence outside the United Kingdom, especially in North America. Today, the Charter enjoys greater prestige in the United States, the land of lawyers, than in Britain. U.S. citizens claim Magna Carta as a source of their liberties, guaranteeing âdue process of lawâ and condemning âexecutive privilegeâ.
