This ethnographic study is a revisionist view of the most significant and widely known mission system in Latin America—that of the Jesuit missions to the Guaraní Indians, who inhabited the border regions of Paraguay, Argentina, and Brazil. It traces in detail the process of Indian adaptation to Spanish colonialism from the sixteenth through the early nineteenth centuries. The book demonstrates conclusively that the Guaraní were as instrumental in determining their destinies as were the Catholic Church and Spanish bureaucrats. They were neither passive victims of Spanish colonialism nor innocent “children” of the jungle, but important actors who shaped fundamentally the history of the Río de la Plata region. The Guaraní responded to European contact according to the dynamics of their own culture, their individual interests and experiences, and the changing political, economic, and social realities of the late Bourbon period.

In Colonial Kinship: Guaraní, Spaniards, and Africans in Paraguay, historian Shawn Michael Austin traces the history of conquest and colonization in Paraguay during the sixteenth and seventeenth centuries. Emphasizing the social and cultural agency of Guaraní—one of the primary indigenous peoples of Paraguay—not only in Jesuit missions but also in colonial settlements and Indian pueblos scattered in and around the Spanish city of Asunción, Austin argues that interethnic relations and cultural change in Paraguay can only be properly understood through the Guaraní logic of kinship. In the colonial backwater of Paraguay, conquistadors were forced to marry into Guaraní families in order to acquire indigenous tributaries, thereby becoming “brothers-in-law” (tovajá) to Guaraní chieftains. This pattern of interethnic exchange infused colonial relations and institutions with Guaraní social meanings and expectations of reciprocity that forever changed Spaniards, African slaves, and their descendants. Austin demonstrates that Guaraní of diverse social and political positions actively shaped colonial society along indigenous lines.
