RESUMO

The Upper Rio Negro regional social system is made up of more than 30 languages belonging to six linguistic families. This results from socio-historical processes stretching back at least two millennia, which have built a system with different levels of autonomy and hierarchy associated with a mythical and ritual complex, and with social and linguistic exchanges. The analysis of these processes require an interdisciplinary outlook to understand the ways in which people from different linguistic families interacted and created it. More specifically, we ask how linguistic and cultural diversity have been created in the context of intense relations of multilingualism and inter-ethnic contact. To this end, we integrate perspectives from historical linguistics (regarding languages from the Tukanoan, Arawakan and Naduhup families) with archaeological data from the Amazonian past. Through this multidisciplinary approach, we seek to develop a linguistic-anthropological understanding of the dynamics shaping the region's diversity and inter-ethnic relations. We show that processes creating diversity are interrelated with changes in social histories, and are especially tied to the establishment of new forms of social organization as a result of pre-colonial inter-ethnic relations. This has led to the construction of various local multilingual ecologies connected to macro-regional processes in Amazonia.
