This chapter explores the connections between ‘queer’ theory, which emerged in the 1990s, and postmodernism. Postmodern literary practice, which glories in the ephemeral, the performative, and the fluid and the contradictory, aligns with the spirit of queer theory and its mission to liberate identities dismissed as marginal or non-normative. However, where late-twentieth-century queer writers exposed and challenged homophobic discourses that sought to demonise and deny queer desire (often in direct response to social circumstances, such as the effects of the decriminalisation of homosexuality in Britain in 1967 and the Aids epidemic in the 1980s), the Twenty-First Century has become distinguished by an increasing ‘homonormativity’. This does not mark the end of hostile queer-eradicating discourses, but means that these are at least challenged by an empowering counter-narrative. The chapter examines a wide range of postmodern writing, including work by Jeanette Winterson, Hanif Kureishi, and Alan Hollinghurst, Sarah Waters, and Paul Magrs.
