Indian Lands Near the Unassigned Lands
A month after the Land Run, Cheyenne and Arapahoe delegates were in Oklahoma City to negotiate the future of their lands west and north of the Unassigned Lands.
After the Civil War, Indian tribes that had sided with the Confederacy were forced to cede their land in western Oklahoma to the US government for the later resettlement of other tribes. But the Creeks and Seminoles retained residual claims to the Unassigned Lands. On March 1, 1889, Congress approved a treaty acquiring the Creek claims, and the next day they authorized the acquisition of the Seminole claims and opening of the Unassigned Lands for settlement.
The Cheyenne and Arapahoe tribes were given land in the Cherokee Outlet (north of the Unassigned Lands) and west of the Unassigned Lands by treaty in 1867. In 1889 the winds of change in Washington persuaded tribal leaders to consider opening these lands for non-Indian settlement. On May 23 and 24, 1889 a group of Cheyenne and Arapahoe leaders met with federal officials in Oklahoma City and worked out an agreement. Ratified after a bitter struggle within the tribes, this agreement led to land runs opening their western land on April 19, 1892 and the Cherokee Outlet on September 16, 1893.
