Magna Carta Libertatum (Medieval Latin for the Great Charter of the Liberties), commonly called Magna Carta (also Magna Charta; (the) Great Charter), is a charter agreed to by King John of England at Runnymede, near Windsor, on 15 June 1215.
The Magna Carta brought an end to the absolute power of English sovereigns as they, too, were required to be held accountable by the law. King John had a tumultuous relationship with Pope Innocent III, a controversial figure in the early 13th century who claimed supreme authority over European sovereigns.
