Scholarship on slavery in the Caribbean frequently emphasizes sugar and tobacco production, but this unique work illustrates the importance of the region’s hato economy—a combination of livestock ranching, foodstuff cultivation, and timber harvesting—on the living patterns among slave communities. David Stark makes use of extensive Catholic parish records to provide a comprehensive examination of slavery in Puerto Rico and across the Spanish Caribbean. He reconstructs slave families to examine incidences of marriage, as well as birth and death rates. The result are never-before-analyzed details on how many enslaved Africans came to Puerto Rico, where they came from, and how their populations grew through natural increase. Stark convincingly argues that when animal husbandry drove much of the island’s economy, slavery was less harsh than in better-known plantation regimes geared toward crop cultivation. Slaves in the hato economy experienced more favorable conditions for family formation, relatively relaxed work regimes, higher fertility rates, and lower mortality rates.
