This dissertation conducts a case study of indigenous women s diplomacies the context of the First indigenous Women s March (Brazil, 2019). It began inquiring about the ways in which those diplomacies differ from state centric conceptions of diplomacy, and also about which were the strategies used by the indigenous women on the March to advance their specific demands as indigenous women. In order to answer those questions, fieldwork with the method of participatory observation was conducted, along with literature review, survey and analysis of documents and interviews using semi-structured questionnaires. Throughout the research, it was realized that, actually, the First March was itself a strategy to deepen political alliances between indigenous women from diverse peoples. As for the second question, due to the multiplicity of diplomatic relations those women stablished during the March, focus was put in three of them: pan indigenous diplomacies of those women both with Brazil as a settler State and with Margarida s March, and the diplomatic relations between women from various peoples. As to the diplomatic relations with the settler State, due to little will from the State to mediate its estrangements with indigenous women, the pan indigenous diplomacy during the March was, in general, a diplomacy of political confrontation. On the other hand, the relations between indigenous women and the Margarida s March involved cosmologic tensions, with pedagogic potentials to non-indigenous women as for the possibilities of political alliances within those cosmological differences. Concerning diplomacies between women from diverse peoples, it was realized that they had a pedagogical character both to educate indigenous men to respect them and to prepare indigenous women to be leaderships. Finally, it was identified that the diplomatic alliances between indigenous women are marked by friendship relations between them, what brings an effective character to those alliances. As to the conclusions achieved, indigenous women s diplomacies in the Brazilian context seem different to interstate diplomacies mainly due to its pedagogical character and its affective dimension.
