This paper explores the depiction of tribal outcry and resistance in the novels of Mahasweta Devi, a doyenne Indian author renowned for her scrutiny of deprived and marginalized communities. Devi’s works, such as Hajar Churashi Maa and Breast Story, offer a heart-touching depiction of the struggles encountered by tribal communities in India, highlighting issues of oppression, deprivation, exploitation, displacement, and social injustice. Devi’s exemplary stories strengthened the voice of unheard tribal communities against the state-sponsored oppression and humiliations of their rights. Devi uses the old methodology of old wives’ tales and symbolism. We can see glimpses of her social activism in her works. The study demonstrates Devi's dedication to influencing mainstream society's perception of tribal and marginalized people. The paper evokes a powerful sense of tribal resistance against the erosion of their land and culture due to development and globalization. Devi portrays tribal women as heroes of her stories as well as victims. Devi’s writing cast light upon the complexity of tribal day-to-day life. It shows how tribal women became the victims of exploitation. There is a strong sense of rage against authoritarian tenure, including colonial and postcolonial. Devi's works position her as the torchbearer of tribal culture. She rose to prominence as one of the leading contemporary writers.
