This work falls within the field of Materialist Discourse Analysis (AD) and its general objective is to analyze posts and comments made on the social network Facebook about the Kulina indigenous people of the municipality of Ipixuna-AM, during the Covid-19 pandemic, more specifically in the period in which the first cases of the disease were recorded in that municipality, in order to identify which discourses are materialized in these texts and the effects of meanings produced there on the aforementioned subjects. To this end, we consider it necessary to describe the conditions of discursive production of these texts, in addition to verifying the subject positions assumed there, with the aim of identifying which discourses appear in the significant materiality of the texts, that is, in the posts and comments published on Facebook. With a view to achieving these objectives, we present the theoretical bases of AD, based on Pêcheux (2009), Althusser (1974), Orlandi (2013) and others, concerning the concepts of language, ideology, subject, discourse, among others, such as are understood in the theory of materialist discourse. We also present the analysis procedures, a brief historical contextualization of the space and the research subjects and finally we undertake the analysis itself, which pointed out the prominent presence of a discourse in the analyzed speeches: the discourse about the indigenous from the colonizer's perspective , responsible for an official version of Brazil's history that has been told and reproduced discursively. These traditional narratives told by official History about the historical presence of indigenous people in Brazil contribute to the maintenance of this calcified imaginary about them and which came to the surface in the texts analyzed here.
