There are two Bannock Tribes. One is non Algonquian, while the other is Anishinabe Algonquian. Their original homeland was located in the Montana-Wyoming region, and also included land in the Great Basin of the western United States, which includes California, Idaho, Nevada, Oregon, and Utah. Bannack, Montana was named after the tribe that lived there and formed an alliance with the white invaders. They no longer live in southwestern Montana. Around 1,000 to 1,300 years ago, prophecy driven Anishinabe soldiers forced their way towards the west from the Great Lakes region and brought nearly all of western North America under their control. They subjugated the native tribes of that region. One of those native tribes were the Bannack. Their language is classified as belonging to the Uto-Aztecan Language family which is partly Anishinabe and non Anishinabe.
When the first whites (they were Spanish) appeared in Bannack country, they eventually learned that two different peoples existed. One were the Anishinabe subjugators, while the other were Bannock who were being subjugated by the powerful Anishinabe Nation. That occurred in possibly the early 17th century. White historians recorded that a large group of Shoshone left their homes in the Montana-Wyoming region, and forced their way to the New Mexico, Oklahoma, and Texas region. They did so to battle the white (Spanish) invaders. They eventually brought the Arizona, New Mexico, and Texas region under Anishinabe control, and then they brought Mexico back under Anishinabe control by 1820. After the whites invented the revolver they wasted little time putting the new weapon to use against the Anishinabe Nation. The whites forced their way in to the east of Texas by 1836. By the 1850s, the whites had forced their way in to the California, Oregon, and Washington region and were commencing their invasion in to the country of the Bannock tribe. That be the Great Basin region.
In the early 1850s, the United States was deliberately causing trouble in Indian Territory (that was located in the present day Colorado, Kansas, and Oklahoma region) and it escalated into the so called 1861-1865 American Civil War. In the late 1840s up to the late 1860s, the whites fought a series of wars against the Anishinabe Nation located in the Great Basin and up in the Montana-Washington-Wyoming region. Once the whites became acquainted with the Great Basin region, they quickly grew to dislike the region and after the wars ended they thought it their best interest to set aside the entire Great Basin to be a huge Reservation for the Anishinabe Nation and their allies. Idaho, Montana, and Wyoming were included in that huge Reservation, as was western South Dakota. When these wars were being fought, the United States actively sought to form alliances with the Bannacks and Utes who were being subjugated by the Anishinabe Nation. Some of the Bannacks and Utes obviously joined the whites to help the whites destroy Native American Nations. Obviously a horrible predicament in their history. It was not only the Bannacks and Utes the whites sought to form alliances with but also Sahaptians (they be Nez Perce) and Salish peoples. Many of them joined with white soldiers to help the whites destroy Native American Nations (themselves).
After the last wars (the 1876-1877 Black Hills War and Nez Perce War, and the 1878 Ute War, and 1879 Sheepeater War - there are two Nez Perce Tribes with one being Anishinabe and the other Sahaptian) ended, peace came but the whites refused to honor treaty agreements with the Anishinabe Nation. The United States created the filthy 1887 Dawes Act which was created specifically to eradicate the Promised Land, or the huge Reservation the United States set aside in the Great Basin region and in the Idaho, Montana, Wyoming, western South Dakota and Washington region. Afterwards, many much smaller Reservations were set aside for the Anishinabek and the Bannock Tribe, Utes, Sahaptians, and the Salish. All Reservations established before 1887 in the Great Basin region, were established for the Sahaptians and Utes. All Reservations established in the western United States in 1887 and after 1887, are Anishinabe Reservations. They were established for small groups of Anishinabe people who followed the Seven Fires Prophecy and fled towards the west. Most ended up in California. Below is a list of the few Bannock Indian Reservations which were established before 1887.
