The American Civil War, widely known in the United States as simply the Civil War as well as other sectional names, was a civil war fought from 1861 to 1865 to determine the survival of the Union or independence for the Confederacy.
The president of the US during the Civil War was Abraham Lincoln. For most of the war it was Abraham Lincoln (1809-1865), who proclaimed that the conflict was ultimately intended to preserve the Union of the United States. Actual hostilities began a month after his inauguration, on April 12, 1861.
