Did the north or south side supported states rights?

The South strongly supported states' rights, as this was a key component of their political ideology, especially in the context of slavery and resistance to federal authority. Southern states argued that they had the right to govern themselves and make their own laws, particularly regarding slavery and economic practices. In contrast, the North generally favored a stronger federal government that could impose laws and regulations uniformly across states, particularly to limit the expansion of slavery. This fundamental difference contributed to the tensions leading up to the Civil War.
