The American System was an economic plan that played a prominent role in American policy during the first half of the 19th century. Rooted in the "American School" ideas of Alexander Hamilton, the plan "consisted of three mutually reinforcing parts: a tariff to protect and promote American industry; a national bank to foster commerce; and federal subsidies for roads, canals, and other 'internal improvements' to develop profitable markets for agriculture".[attribution needed][1] Congressman Henry Clay was the plan's foremost proponent and the first to refer to it as the "American System".
