This study analyzed the multimodal discursive strategies Elisa Loncón, a Mapuche linguist and renowned academic, used on Instagram to position herself as a sociopolitical leader during her tenure as president of the Chilean Constitutional Convention. 811 Instagram posts from her account were downloaded from 15 January 2021 until 15 January 2022. From this, 81 of the most interacted posts were selected and used to examine her multimodal discursive strategies while drawing on the Discourse-Historical Approach (Reisigl and Wodak 2001, 2016). The results revealed three main themes: (1) the construction of an alternative leadership, (2) visibilization of female leadership decision-making, and (3) a vindication of linguistic rights. Referential and intensification strategies were particularly salient, and they were used to legitimize her role and foreground her Mapuche ancestry. These findings highlight how female political leaders (and their intersecting identities) strategically deploy their communication practices to resist sexism and racism.
