American Civil War

The American Civil War (April 12, 1861 – May 26, 1865; also known by other names) was a civil war in the United States between the Union[e] ("the North") and the Confederacy ("the South"), which was formed in 1861 by states that had seceded from the Union. The central conflict leading to war was a dispute over whether slavery should be permitted to expand into the western territories, leading to more slave states, or be prohibited from doing so, which many believed would place slavery on a course of ultimate extinction
