Answer:
Ensure that the king did not act above the law
Step-by-step explanation:
The Magna Carta (1215) was a charter of rights written by a group of Barons of England that were tired of King John’s tyrannic rule. The charter established a more powerful parliament, granted some liberties of free men such as the right to a trial by jury before punishment and reduced the power of King John, whose rule was perceived as abusive especially toward people and in his imposition of high levies, even in the absence of war. Its main purpose was to ensure that the King became subject to the law for the first time in England.
