This article analyzes slave resistance, capital crimes, and state violence in the Mississippi Valley and the Paraíba Valley – two of the most dynamic plantation economies of the nineteenth century. The research focused on the intersection between slavery and criminal law in Brazil and the United States. The analysis of capital crimes committed by enslaved people in Natchez and Vassouras revealed changing patterns of resistance and judicial punishment through the decades. This investigation demonstrated that local experiences of violence on plantations and in courtrooms were connected to the dynamics of national politics and the world economy. Moreover, this comparative study illuminated differences between these racialized slave societies and their political systems and revealed the essence of distinct regimes of racial violence in the Americas.
