What are the similarities between the magna carta and the US Constitution?

Actually, the Magna Carta was written first by the noblemen in Britain to King John of Britain because of the King's abuse of his power. He was not intelligent, nor a great war strategist, nor a brave warrior, nor a honest and kind King. He would often have people executed for speaking out against him. And so, the Magna Carta was drafted in order to put a restraint on the tyrant King. So in June 15th of 1215, the noblemen trapped the King at Runnymeade and forced him to sign it (it was rumoured that the King was illiterate).

Anyway, this situation is increasingly similar to the way the colonies felt about King George III at the time around the American Revolution. How the King would abuse their "certain unalienable rights" such as life, liberty, and (property) the pursuit of happiness (borrowed from enlightenment thinker john Locke). It was also rumoured that the King was mentally insane. And through the war, the King was forced to sign the Treaty of Paris 1783 and renounce Britain's claim on the colonies.

In a more concise way:

Both the situations of the Historical Documents are very similar as well as the content. They both include how the basic rights would be upheld, how everyone was entitled to a jury trial, how the King (any single ruler) would not have the power to throw the people into prison or execute them without a trial, and much more. Even though the Magna Carta refers mainly to the noblemen and the Constitution applies to the common citizens.
