It was probably during the late 17th century when the Assiniboine invaded the central plains of Alberta, Canada. They eventualy made it to the nearby Rocky Mountains. The Assiniboine or the Nakota or Nakoda Indians (to Anishinabe people it is Nakawe or plains Chippewa's or Saulteaux), are a mixture of Anishinabe and Dakotas. However, i have read on the internet that the Assiniboine or Nakota or Nakoda, are Algonquian. It is frustrating to deal with this problem about the nationality of the Assiniboine Indians. It is very obvious they are a mixture of both Anishinabe and Dakotas. These Dakota peoples known as the Nakota or Nakoda, are also known as the Yankton and Yanktonai, and also the Blackfoot and Santee. The mixture of the two Native American peoples commenced probably during the 17th century in northwestern Ontario and northern Minnesota. Anishinabe people have to deal with this obvious cover-up which is very similar to that of the Chippewan (Chipewyan) cover-up.
After the whites signed treaties with the Alberta Indians, the assiniboine alexis nakota first nation or reserve, was created. That event occurred during the 1870s. For more information about the Assiniboine Alexis Nakota Reserve or First Nation, scroll down further on this page. Of supposed Siouan stock, "the Montana Assiniboine Indians" and "the Canadian Assiniboine Indians" are supposedly closely related to their more famous kin, who are better known as the Dakota Nation. However, unlike the Dakota, "the tribe of Assiniboine Indians" were in an alliance with the bitter Ojibwa enemy of the Dakota people. At around 1735, the Iron Confederation was formed in northern Minnesota and northwestern Ontario. It was made up of the Anishinabe (Ojibwas), "the Assiniboine tribe of Indians" and others. Later, the Blackfoot (they are really Anishinabe and Assiniboine or Algonquian) joined the Iron Confederation and what followed was a mass migration of the citizens of the Iron Confederation, out onto the plains of Canada and the United States. Since the Iron Confederation held an advantage over the neighboring tribes, it took them little time to spread out west into Alberta, British Columbia, and into Montana, then into California, Idaho, Nevada, Northwest Territories, Nunavut, Oregon, Utah, Washington, Wyoming, Arizona, New Mexico, and the Yukon where they merged with an earlier group of Anishinabek.
White historians are wrong about the so called Sioux Wars of the 1860s and 1870s. Those wars were between the Iron Confederation and the United States, for control of the Montana region. Those wars include the 1866-1868 Red Clouds War and Snake River War, and the 1876-1877 Black Hills War, and the 1877 Nez Perce War. Assiniboine Warriors participated in all those conflicts on the side of the Iron Confederation. After the Iron Confederation had been defeated by the United States in 1877, "the Assiniboine tribe" were settled down on two large Reservations in Montana. The Fort Belknap Reservation and the Fort Peck Reservation. Up in Canada, "the Assinboine of Canada" probably participated in the so called 1885 Northwest Rebellion. Canadians left "the Assiniboine Anishinabek" with little land, as they had done to the other Anishinabek. After the 1877 Nez Perce War, "the Assiniboine Indians of Montana" and other tribes made their peace with the United States. Crazy Horse and Sitting Bull were probably not Dakota, but probably Anishinabe. The Dakota or Lakota, made their peace with the United States in 1865 and probably allied with the United States to fight the Iron Confederation of the Montana region. Below are the present day "Assiniboine Indian Reservations" in the United States, and "the Assiniboine Indian Reserves in Canada."
