Chapter 3 examines the reorganization of Indigenous regional networks in the areas near to Belém in the Lower Amazon. To avoid enslavement by the Portuguese, some Indigenous communities moved away from the easy-to-access riverbanks. Other Indigenous people successfully engaged with the Crown on their own terms, which allowed them a measure of autonomy to build communities, use their skills for their own benefit, and meet the demands of settlers. These changes and movements led to the development of what the Portuguese called the sertão, a place where people and forest and river products could be retrieved. From an Indigenous perspective, a regrouping occurred as people fled slavery upriver and moved to the riverbank to access colonial goods, such as metal tools.
