A World by Themselves: Protectionism and the Political Economy of Trade in the Ohio Valley, 1816–1828

This paper explores American tariff politics and the embrace of protectionism within the Ohio Valley in the two decades following the War of 1812. During these years, residents of the western states navigated the emergence of steam transportation, a growing number of state-chartered banks, and intense population growth. This fueled an economic boom that went bust during the Panic of 1819. Western farmers, merchants, and manufacturers blamed harmful patterns of trade for this economic crisis, which bolstered a distinct regional identity that embraced a properly constructed restrictive tariff as a “western” measure. Consequently, the decade of the 1820s featured the most sustained period of conflict over the tariff issue in the antebellum era. This article examines western participation in conflicts over commerce and roots the political economy of trade policy in changing economic conditions that inspired distinct northern, southern, and western perspectives on trade and economic development. I conclude that both protectionist claims to economic nationalism and free trade embrace of international exchange overlook the individual assessments of local and regional markets that set the terms on which participants in the tariff debates of the early republic imagined future development.
