This map shows the locations of the new or reduced lands of Indian tribes according to the treaties of 1854. With the passage of the Kansas-Nebraska Act in 1854, the former Indian Territory was opened to white settlement, and the government looked for ways to relocate the native tribes who had made their homes in Kansas. To create more land for white settlement, George Manypenny, the Commissioner of Indian Affairs, negotiated treaties with Indian tribes that ceded much of the Indians' lands to the government. This land could then be sold to white emigrants. Naturally, these events helped to exacerbate existing tensions between settlers and Native Americans, contributing to the Indian Wars that occupied the U.S. Army during and after the American Civil War.
