Because of the reliance on slave labor, by 1860 African American slaves made up at least 25 percent of the county's population. Many Howard County residents supported the Confederacy during the Civil War. After the end of Reconstruction, Jim Crow laws and racial segregation were enforced in the county. Five African Americans were lynched in Howard County between 1891 and 1914. These were Olli Truxton, Frank Embree, Thomas Hayden, Arthur McNeal, and Dallas Shields.
