AbstractHistorians have frequently suggested that droughts helped facilitate the African slave trade. By introducing a previously unused dataset on historical rainfall levels in Africa, I provide the first empirical answer to this hypothesis. I demonstrate how negative rainfall shocks and long-run shifts in the mean level of rainfall increased the number of slaves exported from a given region and can have persistent effects on the level of development today. Using a simple economic model of an individual's decision to participate in the slave trade, along with observed empirical heterogeneity and historical anecdotes, I argue that consumption smoothing and labor allocation adjustments are the primary causal mechanisms for the negative relationship between droughts and slave exports. These findings contribute to our understanding of the process of selection into the African slave trade and have policy implications for contemporary human trafficking and slavery.
