Kentucky in the American Civil War

Kentucky was a southern border state of key importance in the American Civil War. It officially declared its neutrality at the beginning of the war, but after a failed attempt by Confederate General Leonidas Polk to take the state of Kentucky for the Confederacy, the legislature petitioned the Union Army for assistance. Though the Confederacy controlled more than half of Kentucky early in the war, after early 1862 Kentucky came largely under U.S. control. In the historiography of the Civil War, Kentucky is treated primarily as a southern border state, with special attention to the social divisions during the secession crisis, invasions and raids, internal violence, sporadic guerrilla warfare, federal-state relations, the ending of slavery, and the return of Confederate veterans.
