circa 1450. The vision from the
Great Maker that peace would come to all nations led him to spend his life working to bring this to fruition.
In his prophecy, he referred to a white serpent who would come to their lands and make friends with his people, only to later deceive them. According to the prophecy, at the end times, a red serpent would make war on the white one and after a season, a black serpent would come and defeat them both. He said that his nation would accept those of other origins into their safekeeping. Because of their worship of and obedience to the Great Maker, the Iroquois would be protected from the disasters to come.

This wikipedia article does not mention how the Great Peacemakers confederacy influenced the US Constitution.
The Iroquois republic had continuously existed since the 14th or 15th century. In 1930, Arthur Pound 's Johnson of the Mohawk states, wrote "with the possible exception of the also unwritten British Constitution, deriving from the Magna Carta, the Iroquois Constitution is the longest-existing international constitution in the world." Known ad "The Great Law of Peace," this orally transmitted constitution describes a federal union of five (later six) Indian nations: Mohawk, Onondagam Seneca, Oneida, Cayuga and the Tscarora, adopted in 1715. It was only put in writing in 1915 by Arthur C. Parker, archeologist for the State Museum of New York...
During the era, Benjamin Franklin published twenty-six treaty accounts and represented the state of Pennsylvania as an Indian commissioner. In the pre-Revolutionary period, when he and his friends were advocating a federal union of the colonies, no European model was found to be suitable. Franklin 's contact with the Iroquois influenced many key ideas for a new form of government; federalism, equality, natural rights, freedom of religion, property rights, etc. At the 1744 treaty council, by Franklin's account, Canassatego, speaker for the great council at Onondaga, recommended that the colonies form a union in common defense under a federal government: "We are a powerful Confederacy, and by your observing the same methods our wise forefathers have taken, you will acquire much strength and power; therefore, whatever befalls you, do not fall out with one another."
In arguing for such a plan, Franklin stressed the fact that the individual nations of the confederacy managed their own internal affairs without interference from the Grand Council.
Twenty years after Franklin 's plan was defeated at the Albany congress, it reappeared in the Declaration of Independence and the Articles of Confederation. Franklin, Jefferson, John Adams, and George Washington were all familiar with the Iroquois polity. There is also strong scholarly evidence that European philosophers such as Locke, Roussea, More, and Hobbes were familiar with the societies of the American Indians. The integration of this knowledge into their theories of utopias and natural societies further inspired the U.S. founding fathers.
