U.S. Civil War

The American Civil War was a civil war in the United States between the Union and the Confederacy, which was formed in 1861 by states that had seceded from the Union to preserve slavery in the United States, which they saw as threatened because of the election of Abraham Lincoln and the growing abolitionist movement in the North. The war lasted a little over four years and culminated in the dissolution of the Confederacy, the assassination of Abraham Lincoln, and the abolition of slavery, freeing four million African Americans.
