Answer:
(if it is for the magna carta, here is my answer. I am not 100% sure but i wanted to help : ) have a great day or night, wherever you are!! )
The Magna Carta took away the King's power to overly tax, give barons extremely harsh punishments, and commit crimes without punishment. This helped the people because, without sole power, the King was kept in check. This limited abuse of power, and made sure that the king was not above the law.
