Environment, Slavery and Agency in Colonial Uruguay, 1750–1810.

In colonial Uruguay black slaves could supervise the work of white creoles and even hold the power to have their wages docked. To most historians this might seem puzzling and almost fictional in the context of the colonial Americas. This article makes sense of the puzzle by examining interactions between the economy and the environment on the Río de la Plata frontier. It argues that the natural world (soils, topography, climate, crops and animals) contributes to explain why this labour system existed, and also why it was efficient, contrary to the historiographical commonplace that enslaved workers would be unable to oversee free labourers effectively. Looking at the experience of both women and men through the lens of gender uncovers the parallels between the authority of these enslaved foremen over free male workers on the open range and their domestic authority over free women, whom they could marry. Their stories invite historians of other places and periods to foreground the environment in the set of structures that can either limit workers' autonomy or give them strength. [ABSTRACT FROM AUTHOR]
