There were two strains of "Puritans" in England. The Pilgrims believed that the Church of England was unredeemable and preferred to establish their own community somewhere else where they wouldn't be persecuted anymore. They (well some of them) first moved to the Netherlands and later to America. Non-separatist Puritans who remained in England or moved to Massachusetts wanted to "reform" the Church of England instead of establishing their own. They later won the civil war and established a religious dictatorship (well obviously that's grossly oversimplified and there were many other groups besides the puritans which took part in that)... The Plymouth colony was established by the separatists/Pilgrims while most non-separatist Puritans went to New England. The ones in Plymouth were a bit more tolerant (e.g. they didn't hang Quakers like the Puritans in Massachusetts did, only fined then and stripped them of their civil rights, so I guess that's something...)
