Alright. States’s right was easily of the biggest issues during the civil war. The main idea is that the Slaving-owning South believed that the Abolitionist North would eventually make slavery illegal, as the North held more political power then the South. They decided that in order to keep the North from using the federal government to abolish slavery, they would weaken the federal government. Thus the concept of State’s rights was used as an argument for Southern leaders and politicians.
