Union (American Civil War)
During the American Civil War, the United States was referred to as simply the Union, also known colloquially as the North, after eleven Southern slave states seceded to form the Confederate States of America (CSA), which was called the Confederacy, also known as the South. The name the "Union" arose from the declared goal of the United States, led by President Abraham Lincoln, of preserving the United States as a constitutional federal union.
The Union had large advantages in men and resources at the start of the war, and the ratio grew steadily in favor of the Union. In the chart, "cauc men" means white men (Caucasian).
