The American System

A plan to strengthen and unify the nation, the American System was advanced by the Whig Party and a number of leading politicians including Henry Clay, John C. Calhoun and John Quincy Adams.

The American System was a new form of federalism that included:

Support for a high tariff to protect American industries and generate revenue for the federal government

Maintenance of high public land prices to generate federal revenue
Preservation of the Bank of the United States to stabilize the currency and rein in risky state and local banks

Development of a system of internal improvements (such as roads and canals) which would knit the nation together and be financed by the tariff and land sales revenues.

Clay argued that the West, which opposed the tariff, should support it since urban factory workers would be consumers of western foods. In Clay's view, the South (which also opposed high tariffs) should support them because of the ready market for cotton in northern mills. This last argument was the weak link. The South was never really on board with the American System and had access to plenty of markets for its cotton exports.

Clay first used the term "American System" in 1829, although he had been working for its specifics for many years previously.

Portions of the American System were enacted by the United States Congress. The Second Bank of the United States was rechartered in 1816 for 20 years. High tariffs were maintained from the days of Alexander Hamilton until 1832. However, the national system of internal improvements was never adequately funded; the failure to do so was due in part to sectional jealousies and constitutional scruples about such expenditures.

The American System did not enjoy universal success, however. In 1830, President Jackson vetoed a bill which would allow the Federal government to purchase stock in the Maysville, Washington, Paris, and Lexington Turnpike Road Company, which had been organized to construct a road linking Lexington and the Ohio River, the entirety of which would be in the state of Kentucky. Jackson's Maysville Road veto was primarily due to his personal conflict with Clay, rather than ideological objections.

The establishment of a protective tariff, a 20%-25% tax on imported goods, would protect a nation's business from foreign competition. Congress passed a tariff in 1816 which made European goods more expensive and encouraged consumers to buy relatively cheaper American-made goods.

The establishment of a national bank would promote a single currency, making trade easier, and issue what was called sovereign credit, i.e., credit issued by the national government, rather than borrowed from the private banking system. In 1816, Congress created the Second Bank of the United States.

The improvement of the country's infrastructure, especially transportation systems, made trade easier and faster for everyone. Poor roads made transportation slow and costly.

This program became the leading tenet of the Whig Party of Henry Clay and Daniel Webster. It was opposed by the Democratic Party of Andrew Jackson, Martin Van Buren, James K. Polk, Franklin Pierce, and James Buchanan prior to the Civil War.
Among the most important internal improvements created under the American System were the Erie Canal and the Cumberland Road.

Henry Clay's American System devised in the burst of nationalism that followed the War of 1812, remains one of the most historically significant examples of a government-sponsored program to harmonize and balance the nation's agriculture, commerce, and industry. This "System" consisted of three mutually reenforcing 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. Funds for these subsidies would be obtained from tariffs and sales of public lands. Clay argued that a vigorously maintained system of sectional economic interdependence would eliminate the chance of renewed subservience to the free-trade, laissez-faire "British System."
