Responding to Madison's proposals, the 14th Congress compiled one of the most productive legislative records up to that point in history. Madison won the enactment of the Tariff of 1816 relatively easily. The tariff legislation set high import duties for all goods that were produced in the United States at levels that could meet domestic demand; after three years, the rates would decline to approximately 20 percent. Congressman John C. Calhoun argued that the new tariff help create a diversified, self-sufficient economy. The chartering of the new Second Bank of the United States received more opposition, but Congress nonetheless passed a bill granting the bank a twenty-five-year charter. Under the terms of the bill, the United States supplied one-fifth of the capital for the new bank and would select one quarter of the membership of bank's board of directors. Some Tertium Quids like Nathaniel Macon argued that the national bank was unconstitutional, but Madison asserted that the operation of the First Bank of the United States had settled the issue of constitutionality.
