Step-by-step explanation:
The American Civil War (April 12, 1861 – May 9, 1865, also known by other names) was a civil war in the United States fought between northern and Pacific states ("the Union" or "the North") and southern states that voted to secede and form the Confederate States of America ("the Confederacy" or "the South").[e] The Union/North side maintained that the secession was invalid, since the union of the states is permanent. Behind this dispute is the primary cause of the war: the South's desire to not only maintain but expand slavery.
