Election of 1860
The election of 1860 was a complex realigning election in which the breakdown of the previous two-party alignment culminated in four parties each competing for influence in different parts of the country. The result of the election, with the victory of an ardent opponent of slavery, spurred the secession of eleven states and brought about the American Civil War.
