 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 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, combining Plymouth Colony, Massachusetts Bay Colony, and other territories. The official date of the proclamation was October 17, 1691, ending the existence of Plymouth Colony, though it was not put into force until the arrival of the charter of the Province of Massachusetts Bay on May 14, 1692, carried by the new royal governor Sir William Phips. The last official meeting of the Plymouth General Court occurred on June 8, 1692.
