The rubber tappers movement has been interpreted as a local movement that ecloded in Brazil during the 70 s around land right issues. Amazonia in that period was going through a process of modernization, marked by the implementation of projects supported by international institutions, making worse the situation of the rubber tappers. Initially, those actors mobilized for their rights to have lands. But their perception changed by the 80 s, as they got in contact with some actors external to that movement and formed transnational networks around an issue understood at that time as a global problem: the deforestation of the rain forest. Those networks worked together in caimpaigns, targeting Brazilian government through international institutions so as to preserve Amazonia. The object of this study is to analyse the process of transnationalization of the rubber tappers movement, considering the local-global relation and the construction of identity among the actors envolved on such process.
