This article is a literary critical analysis of the autobiographical work, Diario de Bitita, by Carolina Maria de Jesus, (1986). In it the author redates memories of himself to tell the social when he triggers reminiscences of childhood and youth in a post-slavery Brazil, while survives the hardlines and intersectionizes race, class and gender relations in a writing that decolonizes the frameworks and brings to the center themes dear to the black people of this country. In this sense, it is important to point out that decolonial and feminist studies propose a new way of thinking about narratives and relations of oppression, especially when referring to gender and sexuality, as a sociocultural construction. Thus, this article aims to discuss and reflect on writing as reelaboration of memories of oneself and ancestrais crossings through the look of Bitita's childhood, equally collective, as well as reflect on decolonial feminism and the new epistemologies proposed in this sense by the author. Using the qualitative methodology of bibliographic nature from the perspective of interdisciplinary literary criticism that deal with the topics discussed here. Thus, this study is based on theories that help to think of the text as a collective and ancestral memory, Halbwachs (2006), Leda Martins (2003), Cristian Sales (2020) as well as on decolonial feminist studies represented here by Maria Lugones (2014), Ochy Curiel (2020), bell hooks (2019), Djamila Ribeiro (2019) and others that help reflect the caroliana narrative.
