The American Civil War was fought between 1861 and 1865 over the issues of slavery and states' rights. The war began after Southern states seceded from the United States and formed the Confederate States of America. It resulted in the end of slavery and the preservation of the United States as one country, though racial tensions and inequality continued long after the war ended, even with Abraham Lincoln's Emancipation Proclamation and assassination. Over 600,000 soldiers died in the war, making it one of the bloodiest in American history.
