The first government of the United States was chaired by George Washington and relied on the following documents:
Act of Declaration of Independence of the United States of 1776 (Declaration of Independence) and
Constitution of the United States of 1787.
The English Bill of Rights (1689) and Petition of Rights (1628) are important English documents that were very much taken into account in the drafting of the Preamble to the Declaration of Independence Act of the United States and in amendments to the Constitution of the United States. United States, they were not sustenance of the conformation of the first government of the United States.
Magna Carta is a letter granted by John I of England at Runnymede, near Windsor, on June 15, 1215, which at the time of the incipient English Parliament was lost but parliamentarians said that this document had functioned as England's constitution in times past and they assured that the rights of citizens were guaranteed in the face of abuses of the King's authority.
In Victorian times studies were carried out on the Magna Carta and it was discovered that in those times guarantees were given on the rights of the nobles only and not of the citizens.
The Constitution of the United States is conceptually a Magna Carta but does not bear its name.
