Greatest Horse Race - A Centennial Map of the 1889 Oklahoma Land Run
The Land Run of 1889, although not without precedent in the history of the West, began the disposal of the federal public domain in Oklahoma. The legal basis for opening the Oklahoma District, now called the Unassigned Lands, came in 1889 when, in the U.S. Congress, Illinois Rep. William Springer amended the Indian Appropriations Bill to authorize Pres. Benjamin Harrison to proclaim the two-million-acre region open for settlement. Under the provisions of the Homestead Act of 1862, a legal settler could claim 160 acres of public land, and those who lived on and improved the claim for five years could receive a title.
