This important study of Ponce, a major sugar-producing district in Puerto Rico, examines in detail the processes by which a predominantly peasant economy an society was transformed into a plantation system. Scarano’s work, one of the first full investigations into Puerto Rico’s nineteenth-century economic history, dispels the long-held belief that slavery was an inconsequential factor in this society; indeed, he finds that the new plantation system was fully dependent on African slave labor, and that the initial stimuli for economic change came from immigrants.
