The United States Military, State Development, and Slavery in the Early Republic

The U.S. military was the principal agent of American state development in the seven decades between 1791 and 1861. It fought wars, removed Native Americans, built internal improvements, expedited frontier settlement, deterred slave revolts, returned fugitive slaves, and protected existing property relations. These activities promoted state development along multiple axes, increasing the administrative capacities, institutional autonomy, political legitimacy, governing authority, and coercive powers of the American state. Unfortunately, the American political development literature has largely ignored the varied ways in which the presence of slavery influenced military deployments and, in turn, state development during the pre–Civil War period.
