The tariff of 1816 was the first – and last – protective tariff that received significant Southern support during the "thirty-year tariff war" from 1816 to 1846. A number of historical factors were important in shaping Southern perceptions of the legislation. Acknowledging the need to provide sufficient government funding, and with no adequate alternative propositions, the South felt compelled to consider protection. Southern support of the tariff was not demonstrably linked to any significant trend towards industry in the South, or to the existence of textile mills in the Congressional districts of Southern representatives. Southern legislators were keenly aware of the effect that British merchants were having on the US economy and emerging American industries by flooding manufactured goods onto the US market. A group of Southern politicians known as the
War Hawks had been some of the most strident foes of confrontation with Britain and fierce champions of the national government; among these statesmen were Speaker of the House
Henry Clay of Kentucky,
Henry St. George Tucker, Sr. of Virginia and
Alexander C. Hanson of Maryland, all supporting the tariff as a war measure. There were fears among Americans that economic tensions with Britain would lead to a resumption of armed conflict. In that event, a healthy US manufacturing base – including war industries – were vital to the American economy. Rejecting doctrinaire anti-Federalism, Representative
John C. Calhoun of South Carolina called for national unity through interdependence of trade, agriculture and manufacturing. Recalling how poorly prepared the United States had been for war in 1812, he demanded that American factories be provided protection.
John Quincy Adams, as US minister to Great Britain, concurred with Calhoun, discerning a deep hostility from the capitols of Europe towards the fledgling United States.
Old Republicans (also known as "tertium quids"), such as Representative
John Randolph of Virginia, were marginal figures in this struggle, where strict constructionists were at their nadir. This faction of the Jeffersonian Republican Party remained adamant in upholding the principles of state sovereignty and limited government, rejecting any protection whatsoever as an assault upon "poor men and on slaveholders". Among more moderate Southern leaders who remained skeptical about supporting an openly protectionist tariff, there were four additional considerations: First, the tariff was understood to be a temporary expedient to deal with clear and present dangers. The duties would be lowered in three years (June 1819) by which time the strife would likely have subsided. Second, the tariff would only be applied to cotton and woolen products, and iron; the bulk of imported goods the South regularly bought from foreign countries would not be affected. Third, the agrarian South was economically prosperous at the time of the debates, easing concerns about the financial burden the tariff would impose. Those who backed tariffs believed that the economic benefits that would accrue to the North and the West were in
the national interest, and that the South could absorb a mild and temporary increase in the cost of imported goods. Finally, Jeffersonian Republicans, emerging from the War of 1812 with the opposition Federalist Party in disgrace, felt sufficiently in control of the political landscape to permit an experiment in centralizing policies. ==The passage of the tariff==
