Labor questions put their indelible stamp on colonial life, whether in Brazil, Spanish America, or the North American colonies. Methods of labor recruitment varied among these regions, however, as did the social consequences of enslavement, race mixture, and destruction or modification of native cultures.
The poverty of the Amazon region, the old state of Maranhão e Grão Pará, prevented a system of black slavery such as characterized the Brazilian Northeast. Indians, whether slave, or held as free men in mission villages, dominated the labor market. The perennial lay-ecclesiastical fight for jurisdiction over the Indian has been vividly documented by historians such as Boxer, Kiemen, and Leite. This ground need not be retraced. What may be of interest is to examine the variety of sources from which labor was supplied to the plantations, cities, and fortresses of Maranhão e Grão Pará during the first half of the eighteenth century, just before the disruptions brought by Pombal's reforms.
