What was John Calhoun known for advocating during his time as a senator?

John Calhoun was a prominent political figure known for his strong advocacy of states' rights and the principle of limited government. Throughout his career, particularly during his tenure as a senator, Calhoun argued that individual states should have the autonomy to govern themselves and make decisions without excessive interference from the federal government. He believed that this approach was essential to protect the interests of the states and their citizens, particularly in the context of issues such as slavery and tariffs.

Calhoun's views were rooted in the belief that a strong central government could lead to the infringement of states' rights, which he saw as a threat to liberty and self-governance. He emphasized the importance of states acting as "sovereign entities" that could nullify federal laws they deemed unconstitutional. His advocacy played a significant role in shaping the political landscape in the years leading up to the Civil War, influencing discussions around federalism and the balance of power between state and national governments.
