Rocky Boy Tribe of Chippewa Indians of Montana
They are really Anishinabe who absorbed a great many non Anishinabe people among them. Their land was situated just east of the central Anishinabek and was well defended by them after the whiteS invaded in the 16th century. After the white invasion occurred in the 16th century, these Anishinabe people who are really an off-shoot of the western Chippewa's, forced their way eastward into what are now Maine, northern Massachusetts, New Hampshire, New Brunswick, Quebec, and Vermont. They were supported militarily by the other Anishinabe people on up to the end of the war of 1812. Their first wars against the whites occurred during the 1530s, after the Dutch and their French allies, invaded the Saint Lawrence River region. After driving the Algonquin's out of the region between what are now Quebec City and Albany, New York in the 1530s, the Pennacook and other Anishinabek, launched successful military campaigns against the invading whites. They drove the whites out of the fortifications they had established between Quebec City and Albany, by the 1540s, using only their primitive weapons.
Their original homeland was to the west of the Great Lakes. According to the whites who first visited the St. Lawrence River region in the early 16th century, a non Algonquin People were living between Montreal and Quebec City. After Chippewa leaders in the Alberta, Montana, and Wyoming region learned about the long awaited white invasion, they sent 10,000s of the soldiers to the east. They forced their way through the passage where the Upper Peninsula of Michigan is and then forced their way east of the Great Lakes. Any tribes who protested were dealt with extremely harshly. They were either eliminated or forced to get out of the way. One of those tribes were the non Algonquin Tribe which lived between Montreal and Quebec City. According to white historians they were Iroquois. After reaching the region where the Gulf of St. Lawrence is, they subdued the native Algonquin Tribes of that location and absorbed them into their population. While they were busy bringing southeastern Canada under their control, the white invaders were building up their military on islands off the coast of what are now Canada and the United States. In the early 17th century, they had formed alliances with non Algonquin Tribes and launched an invasion. A long war followed.
In the 17th century, the territory of these Chippewa's was located in southern New Hampshire, southern Vermont, and northern Massachusetts. The population of the Pennacook in the United States is included with that of the Abenaki, Maliseet, Passamaquoddy, and Penobscot.
