The concept of ethnogenesis offers a theoretical approach to hybridity and syncretism that finesses the tensions between “New Amazonian Ethnography” and “New Amazonian History” by simultaneously encompassing the study of indigenous ontologies and alternative constructions of history (i.e., “mytho-historical narratives”) as well as the reconstruction of history from all available sources. Ethnogenesis can be defined as a process of authentically re-making new social identities through creatively rediscovering and refashioning components of ‘tradition,’ such as oral narratives, written texts, and material artefacts. Understood in these terms, ethnogenesis allows us to explore the cultural creativity of indigenous and non-indigenous peoples alike in the making of new interpretive and political spaces that allow people to construct enduring social identities while moving forward in the globalizing nation-states of Latin America.
