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 laid the foundation for government based on the rule of law in Great Britain. By the end of the 13th century, England had a representative parliament and had come to recognize Magna Carta as a higher law. The first step toward the growing importance of this document was taken by John's son and successor, Henry III.
