Which best describes why South Carolina seceded from the union

Answer 1

South Carolina seceded from the Union primarily because of their concerns over states' rights and the issue of slavery. They believed that the federal government was overstepping its powers and infringing on the rights of states, particularly regarding the issue of slavery. South Carolina felt that they had the right to maintain and expand slavery within their borders, while the Northern states and the federal government were increasingly opposed to the institution. This disagreement between the Southern states and the rest of the Union ultimately led to South Carolina's decision to secede.
