Debility and Power

An exploration of the powerful and surprising role of debility in the nineteenth-century US South and how it was weaponized to control both land and people

How could a place be at once a life-giving paradise and sinister threat to health? In Debility and Power, Elaine LaFay answers this question by exploring the powerful and surprising role of debility in the nineteenth-century US South, especially the region along the Gulf Coast. Debility, a protean ailment, encompassed shifting ideas of weakness, illness, and impairment over the eighteenth and nineteenth centuries. Lafay argues that debility became a central, yet paradoxical, concept in American expansionism, informing everything from climatic knowledge to the brutal realities of slavery.

The book traces how debility threaded through understandings of the US South, its people, and its “subtropical” climate, which settlers found both tantalizing and terrifying. Even seemingly vulnerable white health-seekers who traveled south for their health acted as agents of colonialism, imagining a landscape emptied of its Indigenous inhabitants and populated with enslaved laborers. At the same time, LaFay uncovers how Black intellectuals and abolitionists wielded debility to mount a blistering critique of slavery as both a moral and physical failing of the nation.

Debility and Power reveals the myriad ways in which debility impacted the daily lives and political projects of nineteenth-century Americans, showing how imperial actors weaponized weakness and fragility to control both land and people. Nineteenth-century science and medicine buoyed these projects, from botany and climatology to theories about wind and ventilation on plantations. Ultimately LaFay argues that fears of debility, and especially debilitating climates, contributed to the naturalization of settler possession of Indigenous land and the justification for the brutal labor of enslaved people.
