Map compiled and drawn by soldier-artist Captain Seth Eastman (1808-1875) of the US Army, showing the various tribes and language groups in what is now Nebraska, Kansas and Oklahoma. The Native American population of the Americas was drastically reduced after the arrival of the Europeans due to war, disease, forced removal and relocation, and the destruction of traditional ways of life. Illustration from 'Information respecting the history, condition and prospects of the Indian tribes of the United States. Part 6' by Henry Rowe Schoolcraft (1793-1864), published in Philadelphia in 1857.
