The CSA was a group of eleven southern states that seceded from the United States in 1861. The secession was in response to the election of Abraham Lincoln as President of the United States. Lincoln was a member of the Republican Party, which opposed the expansion of slavery into new territories. The southern states were largely agricultural, and their economies were based on the production of cotton, which required a large amount of slave labor. The southern states feared that Lincoln would abolish slavery, which would have devastating consequences for their economies.
The secession of the southern states led to the outbreak of the Civil War. The war lasted for four years and resulted in the defeat of the Confederacy. The war had a profound impact on the United States. It led to the abolition of slavery, the reunification of the country, and the strengthening of the federal government.
