Queer theory is primarily concerned with the social construction of gender and sexuality, and how these categories are used to create and maintain power structures.

Performativity, discursivity, and heteronormativity are all key concepts in queer theory. Performativity refers to the idea that gender and sexuality are not fixed identities, but rather are performed and enacted through everyday actions and interactions. Discursivity refers to the idea that gender and sexuality are constructed through language and discourse. Heteronormativity refers to the idea that heterosexuality is the norm and all other sexualities are deviant.

Michel Foucault, Judith Butler, and Eve Kosofsky Sedgwick are all considered to be founding figures of queer theory. Foucault's work on power and sexuality, Butler's work on performativity, and Sedgwick's work on queer desire have all been influential in the development of queer theory.
