Answer:
The South seceded over states' rights. Confederate states did claim the right to secede, but no state claimed to be seceding for that right. In fact, Confederates opposed states' rights — that is, the right of Northern states not to support slavery.
Step-by-step explanation:
the southern states were all for states' rights because many maintain that the primary cause of the war was the Southern states' desire to preserve the institution of slavery. Others minimize slavery and point to other factors, such as taxation or the principle of States' Rights.
