As revolutions swept across Central and South America in the 1820s and 1830s, Andrew Jackson’s administration undertook a landmark reform that transformed the US foreign policy apparatus into the nation’s first global bureaucracy. With the introduction of Edward Livingston’s 1833 consular reform bill to Congress, the nation embarked on a long path toward the modernization of its consular service in line with the powers of Europe and the new American republics. Despite the popularity of Livingston’s plan to turn a dated US consular service comprised of mercantile elites into a salaried professional bureaucracy, the Jacksonian consular reform dragged on for more than two decades before the passing of a consular bill in 1856. Contrary to Weberian models positing a straightforward path toward bureaucratization, the trajectory of Jacksonian consular reform demonstrates the power of mercantile elites to resist central government regulation just as much as it highlights how petty partisans—the protégé consuls appointed via the Jacksonian “spoils system”—powerfully shaped government policy to achieve personal advantages. In the constant tug-of-war between merchant-consuls and Jacksonian protégés, both groups mobilized competing visions of the “national character” in their correspondence with the Department of State and in the national press. Ultimately, the Jacksonian reform vision of an egalitarian and loyal consular officialdom prevailed over the old mercantile model of consulship as a promoter of national prestige and commercial expertise, but only after protégé consuls successfully exploited merchant-consuls’ perceived inability to compete with the salaried European officials across the sister-republics of the southwestern hemisphere.
