The American state was a republic of patrons and clients throughout the Long Nineteenth Century. Unequal ties of hierarchy and reciprocity went far beyond the partisan administration and electioneering that we associate with the spoils system. As a form of “belated feudalism,” clientelism proved resilient because it was a familial property relation embedded within a diverse and changing society. Officeholding politics subsumed a host of racialized and gendered dependents—White men of lower status, women, children, and the enslaved—into the penumbra of the state, which itself was governed via the extended party household. What elements of patron–client relations endured or changed from the colonial inheritance until the New Deal? This article reinterprets the republic’s classical age, first, by exploring the origins of party patrimonialism, and then, by examining the dynamics of officeholding political economy and the rise of markets for patronage. Political rule before the New Deal had a different orientation. Clientelism fused older lineages of dependence with the kind of profit-seeking exchanges typical of the burgeoning capitalist economy. It was this mixed state, at once patrimonial and capitalist, that proved so difficult to reform at the turn of the twentieth century.
