Magna+Carta

Magna Carta

By 1215, thanks to years of unsuccessful foreign policies and heavy taxation demands, England's King John was facing down a possible rebellion by the country's powerful barons. Under duress, he agreed to a charter of liberties known as the Magna Carta (or Great Charter) that would place him and all of England's future sovereigns within a rule of law. Though it was not initially successful, the document was reissued (with alterations) in 1216, 1217 and 1225, and eventually served as the foundation for the English system of common law. Later generations of Englishmen would celebrate the Magna Carta as a symbol of freedom from oppression, as would the Founding Fathers of the United States of America, who in 1776 looked to the charter as a historical precedent for asserting their liberty from the English crown.
