Arundhati Roy’s literary and political writings constitute a sustained critique of power in its multiple manifestations, ranging from caste and patriarchy to state violence, nationalism, capitalism, and global imperialism. This research article examines how structures of power operate and how resistance is articulated in Roy’s fictional and non-fictional works. Through an analysis of her novels The God of Small Things and The Ministry of Utmost Happiness, alongside selected essays, the study explores Roy’s representation of institutionalized power and her commitment to amplifying marginalized and dissenting voices. Drawing upon postcolonial theory, subaltern studies, feminist criticism, and political discourse, the article argues that Roy’s writing destabilizes dominant narratives and exposes the moral and human costs of authoritarian systems. Resistance in Roy’s works is not always overt or victorious; instead, it often emerges through fragile acts of defiance, memory, storytelling, and survival. By foregrounding those silenced by history and power, Roy transforms literature into a space of ethical intervention and political resistance. The article concludes that Roy’s oeuvre represents a powerful fusion of aesthetics and activism, redefining the role of the writer in contemporary society.
