United States presidential election of 1860, American presidential election held on November 6, 1860, in which Republican Abraham Lincoln defeated Southern Democrat John C. Breckinridge, Democrat Stephen A. Douglas, and Constitutional Union candidate John Bell. The electoral split between Northern and Southern Democrats was emblematic of the severe sectional split, particularly over slavery, and in the months following Lincoln’s election (and before his inauguration in March 1861) seven Southern states, led by South Carolina on December 20, 1860, seceded, setting the stage for the American Civil War (1861–65).
