Resumen de Gender Trouble

Judith Butler’s *Gender Trouble* (1990) is a founding text of queer theory. Butler argues that gender is not an expression of an inner essence but a performance—a repeated set of acts, gestures, and enactments that produce the illusion of a stable core. The book’s central framework, performativity, draws on speech-act theory and poststructuralism to claim that gender is constituted through citation and repetition rather than prior to them. The opening chapters interrogate “women” as a unified subject of feminism, warning that exclusionary identity categories replicate the very power structures feminism opposes. Butler engages Simone de Beauvoir, Michel Foucault, and psychoanalytic accounts from Freud and Lacan, then turns to structuralist anthropology and the incest taboo. She rereads Claude Lévi-Strauss and Gayle Rubin to show how kinship systems rely on the exchange of women and a compulsory heterosexuality that naturalizes binary sex. Her most influential chapter critiques the sex/gender distinction, contending that “sex” is itself a culturally produced category. By examining drag and cross-dressing, Butler illustrates how parody exposes the imitative, contingent nature of all gender. She also asks whether subversive repetitions can disrupt norms, while cautioning that performance is not a voluntary choice but a compelled citation. The book’s final sections address the body, materiality, and the limits of identity politics. Widely debated and sometimes misread as claiming gender is a freely chosen costume, *Gender Trouble* instead insists that agency lies in reworking the norms that produce us. Its reception reshaped feminist, queer, and trans studies and made performativity a lasting keyword in social and cultural theory.
