after the american revolutionary war, the tribe formally organized on november 7, 1785 and included members of the so-called christian tribes of massachusetts, connecticut, rhode island and long island, new york. these included people of mohegan, pequot at groton, connecticut; pequot at stonington, connecticut; narragansett, niantic, and tunxis (farmington) tribes on new england, and the montauk (also a pequot band) of long island though other members of these communities chose to remain as intact nations. under pressure from the victorious american settlers to move west, they began to migrate in the 1780s to land provided to them by the oneida nation of the iroquois in marshall, new york (near waterville, in oneida county), where they formalized their new status. as allies to the patriots, the oneida were allowed to stay in new york on a small reservation. due to hostilities aroused by four of the iroquois nations having allied with the british during the war, and continuing land hunger by new settlers, new york and the united states governments pressured the tribes to remove west of the mississippi river.
