Massachusetts Bay Colony founded by Puritans

In 1630, John Winthrop led the Winthrop Fleet from England to Massachusetts Bay under the 1629 charter of the Massachusetts Bay Company. Puritan settlers established government first at Salem and Charlestown and soon shifted the colony's political center toward Boston. Winthrop's migration turned a trading corporation into a self-governing Puritan commonwealth in New England.

The founding of Massachusetts Bay joined religious purpose to political autonomy in a way unusual within the English empire. Because the company charter traveled across the Atlantic with Winthrop and the freemen, the General Court could govern locally rather than through officials appointed from London. Massachusetts Bay therefore developed a strong tradition of town meetings, covenant theology, and magistrate rule that shaped later conflicts from the Antinomian Controversy to the Salem witch trials.

The colony's institutional growth produced the General Court, Harvard College in 1636, and the wider Great Migration that carried Puritan settlements across New England. Massachusetts Bay also became the parent colony from which Connecticut, New Hampshire, and Rhode Island emerged through charter disputes, religious dissent, and migration.
