[2] Logan County is part of the Oklahoma City, OK metropolitan statistical area.

The town of Guthrie was designated as the county seat and the capital of Oklahoma Territory.

[3][4] The land in what became Logan County had been settled during the 1820s and 1830s by the Creek and Seminole tribes after the forced Indian Removal by the federal government from their traditional historic territories in the American Southeast.

The United States required the tribes that supported the Confederacy to make new Reconstruction Treaties in 1866.

Congress passed a law in 1889, after the Indian Wars, to open the land to non-Indian settlement under terms of the 1862 Homestead Act.

The three easternmost townships were added to the county in 1891, after areas of the Sac and Fox lands were also opened to non-Indian settlement, following allotment of communal lands to individual tribal households under implementation of the Dawes Act.

The US classified lands remaining after allotment as "surplus" and allowed them to be sold to non-Natives.

After the land run, Guthrie, Oklahoma developed into a center of trade for the county and region, connected by railroads to other markets.

Barack Obama barely received a quarter of the county's vote in 2012, a poorer showing than that of even George McGovern in 1972.

No Democratic candidate for governor has carried the county since Brad Henry in 2006, or for U.S. Senate since David Boren in 1990.
