Sectionalism, States' Rights, and Nullification

Sectionalism is basically the tensions between regions in a country. States' rights explains its self - it is when a state believes that its rights/needs are more important than the federal government's rights/needs. Nullification is a state ignoring a federal law. How do these have to do with the Civil War? In 1832, South Carolina declared states' rights by ignoring a federal law (nullification). The president at the time, Andrew Jackson, was outraged. He sent troops to South Carolina as a threat. This almost started a war. Jackson eventually pulled back the troops; and also preventing a war by sectionalism.
