Look..
Civil War: In U.S. history, the conflict (1861 ; 65) between the Northern states (the Union) and the Southern states that seceded from the Union and formed the Confederacy. It is generally known in the South as the War between the States and is also called the War of the Rebellion (the official Union designation), the War of Secession, and the War for Southern Independence. The name Civil War, although much criticized as inexact, is most widely accepted.
