John Winthrop (12 January 1587/88 – 26 March 1649) was an English Puritan lawyer and one of the leading figures in founding the Massachusetts Bay Colony, the second major settlement in New England, following Plymouth Colony. Winthrop led the first large wave of immigrants 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.
Between 1629 and his death in 1649, he served 18 annual terms as governor or lieutenant-governor and was a force of comparative moderation in the religiously conservative colony, clashing with the more conservative Thomas Dudley and the more liberal Roger Williams and Henry Vane. Winthrop was a respected political figure, and his attitude toward governance seems authoritarian to modern sensibilities. He resisted attempts to widen voting and other civil rights beyond a narrow class of religiously approved individuals, opposed attempts to codify a body of laws that the colonial magistrates would be bound by, and also opposed unconstrained democracy, calling it "the meanest and worst of all forms of government". The authoritarian and religiously conservative nature of Massachusetts rule was influential in the formation of neighboring colonies, which were formed in some instances by individuals and groups opposed to the rule of the Massachusetts elders.
Winthrop's son John was one of the founders of the Connecticut Colony, and Winthrop himself wrote one of the leading historical accounts of the early colonial period. His long list of descendants includes famous Americans, and his writings continue to influence politicians today.
