The Civil War marked a defining moment in United States history. Long simmering sectional tensions reached a critical stage in 1860–1861 when eleven slaveholding states seceded and formed the Confederate States of America. Political disagreement gave way to war in April 1861, as Confederates insisted on their right to leave the Union and the loyal states refused to allow them to go. Four years of fighting claimed almost 1.5 million casualties (killed, dead from disease, wounded, or taken prisoner, and of whom at least 620,000 died) directly affected untold civilians, and freed four million enslaved African Americans.More »
