United States [SEP] Civil War and Reconstruction era
Irreconcilable sectional conflict regarding the slavery of Africans and African Americans ultimately led to the American Civil War. With the 1860 election of Republican Abraham Lincoln, conventions in thirteen slave states declared secession and formed the Confederate States of America (the "South" or the "Confederacy"), while the federal government (the "Union") maintained that secession was illegal. In order to bring about this secession, military action was initiated by the secessionists, and the Union responded in kind. The ensuing war would become the deadliest military conflict in American history, resulting in the deaths of approximately 618,000 soldiers as well as many civilians.
