In 1834, the federal government had passed an act that designated the entire Great Plains as one enormous reservation, or land set aside for Native American tribes. In the 1850s, however, the government changed its policy and created treaties that defined specific boundaries for each tribe. Most Native Americans spurned the government treaties and continued to hunt on their traditional lands clashing with settlers and miners, with tragic results.
The government’s continuous changing of American Indian policy caused mistrust.
