A group of English Puritans founded the Plymouth Colony in 1620, just to the south of Massachusetts Bay. The Puritans encouraged further colonial settlement and immigration to the New World because King Charles I of England was in favor of suppressing the religious practices of Puritans in England. Eventually in 1629, the Cambridge Agreement was signed in England among some of the Puritans, established a self-governing colony, the Massachusetts Bay Colony, and they decided to settle to the New World. John Winthrop was their leader; he would become governor of the settlement in the New World. In a famous sermon before the Puritans' departure, "A Model of Christian Charity," Winthrop described the new colony as "a City upon a Hill."
