Why was calhoun not satisfied with Henry clays compromise?

John C. Calhoun was not satisfied with Henry Clay's Compromise of 1850 because he believed it failed to adequately protect the interests of the Southern states and their institution of slavery. Calhoun felt that the compromise did not provide enough safeguards against the potential expansion of free states, which he feared would diminish the South's political power and economic interests. He advocated for a stronger assertion of states' rights and the protection of slavery, viewing the compromise as a temporary fix rather than a long-term solution to the growing sectional tensions.
