My lord, we the nobles have agreed upon a document to limit your power. Sign it, or there shall be war.
Alright, I shan't go to war over such a silly matter. Give it here.
I, King John, agree upon the terms of this here document, the Magna Carta, and all that it entails.
Without the Magna Carta, we wouldn't have the laws and the order in society that we have today, because the president or any branch would have a lot of power, and many of us would probably be suffering at the hands of a dictator or tyrant.
