Hightower frames his story within the larger history of Old Oklahoma, beginning in Indian Territory, where displaced tribes and freedmen, wealthy cattlemen, and prospective homesteaders became embroiled in disputes over public land and federal government policies. Against this fraught background, 1889 travels back and forth between Washington, D.C., and the Oklahoma frontier to describe the politics of settlement, public land use, and the first stirrings of urban development. Drawing on eyewitness accounts, Hightower captures the drama of the Boomer incursions and the Run of '89, as well as the nascent urbanization of the townsite that would become Oklahoma City. All of these events played out in a political vacuum until Congress officially created Oklahoma Territory in the Organic Act of May 1890.

The story of central Oklahoma is profoundly American, showing the region to have been a crucible for melding competing national interests and visions of the future. Boomers, businessmen, cattlemen, soldiers, politicians, pundits, and African and Native Americans squared off--sometimes peacefully, often not--in disagreements over public lands that would resonate in western history long after 1889.
