If south was for slavery why were they fighting states rights?

The southern states fought for states' rights because they wanted to preserve the institution of slavery. They believed that the federal government should not have the power to interfere with slavery in the states. The southern states also believed that they had the right to secede from the Union if the federal government did not protect their interests.

The issue of slavery was a major factor in the Civil War. The southern states seceded from the Union and formed the Confederate States of America in order to protect their right to own slaves. The northern states, on the other hand, believed that slavery was morally wrong and that the federal government had the right to abolish it. The Civil War was fought between the Union and the Confederacy from 1861 to 1865. The Union won the war and slavery was abolished in the United States.
