Plymouth Colony is Dissolved with Arrival of Charter Annexing it to Massachusetts Bay Colony
In 1686, the entire region was reorganized under a single government known as the Dominion of New England; this included the colonies of Plymouth, Rhode Island, Massachusetts Bay, Connecticut, and New Hampshire.
In 1688 New York, West Jersey, and East Jersey were added. The President of the Dominion, Edmund Andros, was highly unpopular, and the union did not last. Plymouth Colony revolted and withdrew from the Dominion in April 1688; the entire union was dissolved during the Glorious Revolution of 1688.
The return of self-rule for Plymouth Colony was short-lived, however. A delegation of New Englanders, led by Increase Mather, went to England to negotiate for a return of the colonial charters that had been nullified during the Dominion years. The situation was particularly problematic for Plymouth Colony, as it had existed without a formal charter since its founding. Plymouth did not get their wish for a formal charter; instead a new charter was issued, annexing Plymouth Colony to Massachusetts Bay Colony. The official date of the proclamation ending the existence of Plymouth Colony was October 17, 1691, though it was not put into force until the arrival of the new charter on May 14, 1692, carried by William Phips. The last official meeting of the Plymouth General Court occurred on June 8, 1692.
Plymouth Colony retained its independence for over 70 years, and by 1691 its population exceeded 7,000. It was integrated with the Massachusetts Bay Company's much larger colony to establish the royal colony of Massachusetts — now the state of the same name.
