What three issues did Jackson and Calhoun clash?

Andrew Jackson and John C. Calhoun clashed primarily over the issues of states' rights, nullification, and the role of the federal government. Calhoun advocated for the doctrine of nullification, which allowed states to reject Federal Laws they deemed unconstitutional, while Jackson firmly opposed this, asserting the supremacy of federal authority. Their disagreements intensified during the Nullification Crisis of the early 1830s, where Jackson's commitment to preserving the Union put him at odds with Calhoun's defense of state sovereignty. Additionally, their differing views on economic policies and the national bank further strained their relationship.
