Consider the following articles I found on the Web:
"Vast portions of five U.S. states — North Dakota, South Dakota, Nebraska, Wyoming and Montana — are Indian land according to a treaty to which the American government voluntarily assented. The highest legal authority in the United States has acknowledged that a significant portion of the land in question is rightfully Lakota. The American government refuses to return that land....Americans have unjustly taken vast tracts of land. This President's Day, let's uphold our treaties and return it." - North Dakota Has Way, Way, Way More Oil Than We Thought
"This war was brought upon us by the children of the Great Father who came to take our land from us without price." - Teaching With Documents - The Sioux Treaty of 1868
"In 1805 the Dakota ceded 100,000 acres of land at the confluence of the Mississippi and Minnesota rivers. U.S. Army Lt. Zebulon Pike negotiated the agreement so the U.S. government could build a military fort there. Of the seven Indian leaders present at the negotiations, only two signed the treaty. Pike valued the land at $200,000, but no specific dollar amount was written into the treaty. At the signing, he gave the Indian leaders gifts whose total value was $200. The U.S. Senate approved the treaty, agreeing to pay only $2,000 for the land. Generally, the Indians who signed treaties did not read English. They had to rely on interpreters who were paid by the U.S. government. It is uncertain whether they were aware of the exact terms of the treaties they signed." (emphasis mine) - The US - Dakota war of 1862
