Niantic 

It appears that the Niantic occupied the entire coastline of eastern Connecticut as a single tribe before they were physically separated by an invasion of the Pequot-Mohegan from the northwest shortly before the Pilgrims arrived at Plymouth in 1620. The warfare and conquest apparently coincided with the devastating wave of epidemics which swept New England (1614-17).

Nipissing 

Probably their most interesting feature was their reputation among other tribes for the spiritual power of their shamans. Unfortunately, some of their neighbors were also prone to accusing them of sorcery as a result.   

Nipmuc 

The Nipmuc generally lived along rivers or on the shores of small lakes and seem to have occupied the area for as far back as can be told. Like other New England Algonquin, the Nipmuc were agricultural. They changed locations according to the seasons, but always remained within the bounds of their own territory. Part of their diet came from hunting, fishing, and gathering of wild food, but as a rule they did not live as well as the coastal tribes who had the luxury of seafood. Each group was ruled by its own sachem, but there was very little political organization beyond the village or band level.
