What did the opponents of the first national bank relied on which idea to bolster their arguments?

Opponents of the First National Bank relied on the idea of strict interpretation of the Constitution to bolster their arguments. They contended that the Constitution did not explicitly grant the federal government the power to create a bank, viewing it as an overreach of federal authority. This perspective was rooted in the belief that powers not explicitly enumerated should be reserved for the states, reflecting a broader concern about centralization of power and potential tyranny.
