American Civil War

n. civil war that was fought in the United States from 1861 to 1865 between the North and the South

"The Civil War" is the most common term in the United States for this conflict. See Naming the American Civil War. The American Civil War (1861–1865) was a major  war between the United States (the "Union") and eleven Southern slave states which declared that they had a right to secession and formed the Confederate States of America, led by President Jefferson Davis. The Union, led by President Abraham Lincoln and politically dominated by his Republican Party, included all of the free states and four slaveholding border states that were later joined by pro-Union counties of Virginia (see West Virginia). Republicans opposed the expansion of slavery into territories owned by the United States, which increased Southern desires for secession. However, Republicans (and the previous Democratic administration under Buchanan) rejected any right of secession. Fighting commenced on April 12 1861, when Confederate forces attacked a United States (federal) military installation at Fort Sumter in South Carolina, the first state to secede.
