The Magna Carta was a charter signed by King John of England in 1215 that placed limitations on the power of the monarchy. It required the king to renounce certain rights and accept that his will could be bound by law. The Magna Carta protected certain liberties and became an important symbol of the rule of law over the absolute power of English kings. It established a committee of barons that could override the king if he violated the charter's terms. Some clauses from the Magna Carta remain in effect in English law today.
