The national bank was one of the biggest controversies of the early American republic. Hamilton wished to create a national bank in order to assume states’ debts from the Revolution and build the new nation’s credit by paying it back through a central bank. Antifederalists and later Democratic-Republicans argued against the bank’s creation, saying that Congress wasn’t given the power to create the bank in the Constitution. Federalists, especially northern merchants, who would gain from Hamilton’s financial plan, supported the bank.
