John Winthrop (12 January 1588 – 26 March 1649) led a group of English Puritans to the New World, joined the Massachusetts Bay Company in 1629 and was elected their governor in October 1629. Between 1639 and 1648 he was voted out of governorship and re-elected a total of 12 times. Although Winthrop was a respected political figure, he was criticized for his obstinacy regarding the formation of a general assembly in 1634.
