The â€˜Mayflowerâ€™ settlers reached New England in 1620, and within a few years the Puritans among them had established the Massachusetts Bay Colony, with about 20,000 additional migrants swelling the population during the 1630s. The Colonyâ€™s founding fathers were very clear as to their purpose: they wanted to form a Puritan Commonwealth, one which would serve as a model, an example for all others. As John Winthrop (a later Governor) put it: â€˜We shall be as a city upon a hill. The eyes of all people are upon usâ€™. To bring about this model Puritan colony, the citizens were heavily policed by the ministers, men who were committed to the enforcement of Calvinâ€™s threefold use of the law, and, in prosecution of their aim, highly intolerant of all dissent.
