Answers

The Medicine Lodge Treaty is the collective name for three treaties signed in October 1867 near Medicine Lodge, Kansas, between the Federal government of the United States and southern Plains Indian tribes to bring peace to the area by relocating Native Americans to reservations in Indian Territory and away from European-American settlement.

The treaty was negotiated following an investigation by the Indian Peace Commission, which concluded in its final report in 1868 that the wars could have been avoided. They determined that the United States government and its representatives, including the United States Congress, contributed to the Great Plains war by failing to fulfil their legal obligations and to treat Native Americans fairly.
