Question

How did the Magna Carta restrict the power of the king? What benefit did the nobles receive from restricting the king?

Answer 1

The Magna Carta meant that 
1) the nobles (the barons) could not be imprisoned without a fair trial (restricting the power of the king to imprison)
2) the king could not raise new taxes without a council of baron's approval (restricting the power of the king to raise new taxes)
Explanation:
The Magna Carta was signed by King of England in June 1215 and was the primary document to inflict legal limits on the king's personal powers. Clause sixty one declared that a committee of twenty 5 barons may meet and overthrow the desire of the king—a serious challenge to John's authority as ruling monarch.
This has been the most concern of the nobles within the years preceding the document as a result of taxes had been raised to fund a war against France. The nobility benefited as a result of the royal charter outlined individual rights and emphasised the role of laws in society. Clause thirty-nine states, for instance, that folks ought to be corrected solely once a ruling by their peers or by the sanctions of the law.
