Did the magna carta make the king more powerful?

The most important document in American Government is the Constitution. The Magna Carta is the first of a series of documents leading to the rights guaranteed by the Constitution of the United States. The Magna Carta is important in that it is the first of many. Being at the head of the line makes it quite important. Still, the other documents that continued the line contained more rights. If they had not existed the Magna Carta would be forgotten.
