Which President expanded presidential powers while opposing individual states' rights to nullify federal laws?

Andrew Jackson is the president who expanded presidential powers while opposing individual states' rights to nullify federal laws. During his presidency, particularly notable was his confrontation with South Carolina during the Nullification Crisis in the early 1830s. South Carolina attempted to nullify federal tariffs, arguing that states had the right to reject federal laws they deemed unconstitutional. Jackson took a strong stance against this position, firmly upholding the supremacy of federal law.

By issuing a proclamation against nullification and seeking to enforce the tariffs, Jackson demonstrated a considerable expansion of presidential authority, asserting that the federal government had the right to maintain its laws even against state opposition. His response included the threat of military action against South Carolina, highlighting his commitment to preserving the Union and federal power. This action laid the groundwork for a more assertive federal government, setting a precedent for future interactions between state and federal authorities.
