Rocky Boy Tribe of Chippewa Indians of Montana
According to William W. Warren, the Sac or Sauk, had the Anishinabe name "O-sau-gee." You pronounce it similar to o-sa-ki! What you do not realize in the name "O-sau-gee," will surprise you! Remove the "u" and the last "e" and we get "Osage." You now know the Sauk are the Osage Indians! The Osage originally lived in the area of southern Michigan where the Swan Creek and Black River Chippewa's lived. They are the Swan Creek and Black River Chippewa's or Saginaw Chippewa's! Sac is short for Saginaw. Sauk is short for the Chippewa name O-saag-gi.
The November 3, 1804 & August 24, 1816 Treaties
According to historians, the Sac or Sauk who are really the Swan Creek and Black River Chippewa's or Saginaw Chippewa's, signed a treaty in which they ceded land in Wisconsin, Illinois, and Missouri. At the Library of Congress websites Indian land cession maps, it has the numbers 50 and 1. They did not cede that land. The Chippewa's led the War of 1812. On August 24, 1816, the Chippewa's supposedly ceded land in Wisconsin and Illinois, which was ceded by the Sac or Sauk, on November 3, 1804. It didn't happen! This is why!
On July 29, 1829, the United States again tried to force the Chippewa's to cede the land they claim was ceded to the United States when the November 3, 1804 Treaty was illegally signed. Neither the November 3, 1804 Treaty, August 24, 1816 Treaty, nor the July 29, 1829 Treaty are legitimate. In 1832, the United States launched a military campaign to force the Chippewa's of Illinois, Missouri, and Wisconsin to cede the land they demanded for on November 3, 1804. The short and brutal 1832 Black Hawks War, did not resolve the Greed problem. The area of land in Wisconsin (it has the number 147), and Illinois (it has the numbers 50 and 147), and Missouri (it has the number 50) is disputed land or a Chippewa Reservation the Chippewa's refused to cede. The Chippewa's migrated to the west and north, after the 1832 war. They left the land cession unresolved.
The November 17, 1807 Treaty
According to historians, the Swan Creek and Black River Chippewa's or Saginaw Chippewa's, signed the November 17, 1807 Treaty which ceded land in southeastern Michigan and the adjoining area of Ohio. It has the number 66 on Michigan and Ohio land cession maps at the Library of Congress website about Indian land cessions. The Chippewa's led the war of 1812 which means they did not cede that land area.
The May 9, 1836 Treaty
Another treaty was signed on May 9, 1836 in which the Swan Creek and Black River Chippewa's or Saginaw Chippewa's, ceded the Reservations set aside for them when they signed the November 17, 1807 Treaty. Since the Chippewa's did not sign the November 17, 1807 Treaty, it means the May 9, 1836 Treaty is invalid. The entire land area in Michigan and Ohio with the number 66, is either disputed land or a Chippewa Reservation.
The 1838-1839 Exodus
Soon after the failed May 9, 1836 Treaty, the Swan Creek and Black River Chippewa's or Saginaw Chippewa's, followed the Seven Fires Prophecy, and migrated to the west. Many even migrated north up to Canada. This event is better known as the Cherokee Trail of Tears of 1838 and 1839. They migrated into Illinois then Missouri then into eastern Kansas and eastern Oklahoma.
Today, the Sac or Sauk, no longer know they are Chippewa. They believe what the whites tell them. They have Reservations in Iowa, Kansas, and Nebraska. In fact, the Sac Reservation in Nebraska borders the old 5 million acre Chippewa Reservation in Iowa, extreme southern Minnesota, and extreme northwestern Missouri. It's proof they are Chippewa. They also live in Oklahoma but do not have a Reservation in Oklahoma.
