Gender, sexuality, and queer theory in literature challenge traditional notions of identity and representation. These concepts explore how societal norms shape our understanding of gender roles, sexual orientation, and power dynamics in literary works. Queer theory emerged in the 1990s, influenced by poststructuralist thinkers. It examines how texts construct or subvert normative ideas about gender and sexuality, encouraging readers to consider multiple interpretations and the intersectionality of characters' experiences.
