Answer:
(1) States rights
Step-by-step explanation:
Although many say that slavery was the main cause of the Civil War, you can actually blame almost or just as much on this matter specifically.
The Southern States did not want to be subject to whatever the Federal government wanted. They considered that the Federal government was being intrusive and meddling with things that it should not. And of course, much of that was because of how the Federal Government wanted to intervene in Slavery, but it's more than just that.
