Tennessee played an important but divided role in the Civil War. It was the last Confederate state to secede due to divisions between its eastern, western, and middle regions. Several key figures influenced the course of the war, including Confederate president Jefferson Davis and generals Robert E. Lee and Stonewall Jackson, as well as Union admiral David Farragut and politicians William Brownlow and Nathan Bedford Forrest of Tennessee. African American regiments like the 54th Massachusetts and 13th United States Colored Troops from Tennessee played significant roles despite facing prejudice.
