text: I will agree with you on the point about the land being taken but all of the tribes agreed to the Treaty of 1868 and the reservation boundaries as they were set up. That means the land was not stolen, just obtained under duress. Those were different times and not nice times either. The Standing Rock reservation's northern boundary was at the 46th parallel and the Missouri River, which was a few miles south of the Cannon Ball River. In 1873, there was an executive order that extended the northern border to the Cannon Ball River, which is where the boundary is today. Still a bit south of the pipeline. The only land that the Sioux Tribes officially say is stolen, and they are right, was the Black Hills in the Treaty of 1877. That was done in direct violation of section 2 of the Treaty of 1868, requiring the approval of a good sized majority of the Sioux. The Sioux never approved the annexation. That is not rewriting history, that is reciting factual history.
