Magna Carta

The Magna Carta (Latin for "Great Charter") was an English charter written in 1215, which limited the power of English Monarchs, specifically King John, from absolute rule. Magna Carta was the result of disagreements between the Pope and King John and his barons over the rights of the king: Magna Carta required the king to renounce certain rights and respect certain legal procedures, and to accept that the will of the king could be bound by law. Magna Carta is widely considered to be the first step in a long historical process leading to the rule of constitutional law.
