Conditions in America did more than lend color to pale speculation; they seemed to take this hypothesis out of the realm of theory and to give it practical application. What happened when men went into the wilderness to live? The Pilgrim Fathers on board the Mayflower entered into an agreement which was signed by the heads of families who took part in the enterprise: "We, whose names are underwritten . . . Do by these presents, solemnly and mutually, in the Presence of God and one another, covenant and combine ourselves together into a civil Body Politick."

Other colonies, especially in New England, with this example before them of a social contract entered into similar compacts or "plantation covenants," as they were called. But the colonists were also accustomed to having written charters granted which continued for a time at least to mark the extent of governmental powers. Through this intermingling of theory and practice it was the most natural thing in the world, when Americans came to form their new State Governments, that they should provide written instruments framed by their own representatives, which not only bound them to be governed in this way but also placed limitations upon the governing bodies. As the first great series of written constitutions, these frames of government attracted wide attention. Congress printed a set for general distribution, and numerous editions were circulated both at home and abroad.
