The Magna Carta was a charter of rights that placed a more influential parliament, affirmed the rights of free men and that lessened the authority of King John. The rule of King John was regarded as abusive particularly toward people. Moreover, he placed high rates of taxes even in the peace season. Accordingly, the English nobles who were unhappy with his rule asked him to sign the "Great Charter or the Magna Carta. This law made the king and everyone the subject to law.
<u>Unhappy and tired of King John’s tyrannic rule, a group of Barons of England C) forced him to sign the Magna Carta.</u> The Magna Carta was a charter of rights that established a more powerful parliament, stated the liberties of free men and that 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.
