This research study delves into the life and works of renowned writer, journalist, and social activist, Mahasweta Devi. The book highlights her deep commitment to championing the cause of the downtrodden and human rights, particularly to the de-notified tribes of India. Mahasweta Devi's socially committed literature brought to surface the ugly facet of exploitation in the society of which most people are oblivious. The book aims to explore the way in which the subaltern is represented in the selected works of Mahasweta, with a particular focus on the novels "Mother of 1084," "Rudali," and "Bedanabala." The study utilizes Post-Colonial Theory, Deconstruction, and Counter-Historical discourse to have a broader understanding of the concept of subaltern and the subaltern himself. The book argues that Mahasweta Devi's works reverberate with the oppression, injustice, and depravity that a section of society is subjected to at the hands of the powerhouses or elites. Her writings have a social commitment and highlight the problems and sufferings of the marginalized sections of the community who are termed as 'Subaltern'.
