The Confederate States of America (CSA) was a group of eleven southern states that seceded from the United States between 1860 and 1861. This secession was primarily driven by issues related to slavery and states' rights. The CSA was formed in February 1861, with Jefferson Davis as its president, and it aimed to establish itself as an independent nation. The Civil War ensued shortly after the formation of the CSA, lasting from 1861 to 1865. The conflict arose as the Union sought to preserve the nation, while the Confederacy fought for its independence. Ultimately, the CSA was defeated, leading to its dissolution and the restoration of the Union.
