European-American settlers, starting with the Colorado Gold…
1861 CE
Travel has greatly increased along the Emigrant Trail along the South Platte River and some emigrants stop before going on to California.
For several years there has been peace between settlers and natives.
The only conflicts ware related to the endemic warfare between the Cheyenne and Arapaho of the plains and the Utes of the mountains.
U.S. negotiations with Black Kettle and other Cheyenne favoring peace result in the Treaty of Fort Wise on February 18, 1861, signed by six chiefs of the Southern Cheyenne and four of the Arapaho: it establishes a small reservation for the Cheyenne in southeastern Colorado in exchange for the territory agreed to in the Fort Laramie Treaty of 1851.
Many Cheyenne do not sign the treaty, and they continue to live and hunt on their traditional grounds in the Smokey Hill and Republican basins, between the Arkansas and the South Platte, where there are plentiful buffalo.
