John Winthrop was an English Puritan lawyer and a leading figure in the founding of the Massachusetts Bay Colony, the second major settlement in New England following Plymouth Colony. Winthrop led the first large wave of colonists from England in 1630 and served as governor for 12 of the colony's first 20 years. His writings and vision of the colony as a Puritan "city upon a hill" dominated New England colonial development, influencing the governments and religions of neighboring colonies in addition to those of Massachusetts.

Roger Williams was an English-born New England Puritan minister, theologian, and author who founded Providence Plantations, which became the Colony of Rhode Island and Providence Plantations and later the State of Rhode Island. He was a staunch advocate for religious freedom, separation of church and state, and fair dealings with the Native Americans.
