Overview

The American Civil War was a major conflict that took place in the United States from 1861 to 1865. It was primarily fought between the Northern states, known as the Union, and the Southern states that seceded to form the Confederacy. The main issues at stake were slavery and the rights of states versus the federal government, leading to a bloody and transformative struggle that claimed hundreds of thousands of lives. During the war, the Union aimed to preserve the nation and abolish slavery, while the Confederacy fought to maintain their way of life, which heavily relied on slavery for economic success.
