Consequences of the Black Sea Slave Trade: Long-Run Development in Eastern Europe

We investigate the developmental consequences of slave-raiding in Eastern Europe, the largest source of slaves in the early modern world after West Africa. Drawing on a wide-ranging new dataset, we estimate that at least five million people were captured from hundreds of locations across Eastern Europe between the fifteenth and eighteenth centuries. We hypothesize that, over time, raids encouraged an economically advantageous process of defensive state-building linked to raided societies’ resistance to and lack of integration into the slave trade. Using difference-in-differences and instrumental variables strategies, we find that exposure to raids is positively associated with long-run urban growth and related indicators of demographic and commercial development. Consistent with our posited mechanism, raided areas constructed more robust defensive infrastructures and attained higher levels of military, administrative, and fiscal capacity. Our findings suggest that the structure of slave production conditions its developmental legacies, cautioning against drawing generalizations from the African context.
