Abstract: Enslaved people in the US South lived in a system designed to exploit their labor in pursuit of profit. This historiographical essay considers key questions about labor and power raised in the previous two decades of scholarship on antebellum slavery. What were the forms and meanings of enslaved people’s politics, and how can we track them through the archive? How was slavery connected to other phenomena including empire and capitalism in the early United States? In pursuing these questions, scholars have illuminated the history of slavery at different scales, ranging from the lived experiences of bound workers to transatlantic networks of commerce and credit through which the products of enslaved labor moved. This essay considers some of the different ways recent historians have worked to understand the institution of slavery, with a particular focus on the question of how closely their approaches bring us to understanding the shape of enslaved humanity.
