This collection of focused, cohesive and persuasive essays is based on the newest research on gender, sexuality and sexual politics. It offers historical reflections and contemporary analyses of issues related to the contested and often hidden histories of sexual politics and gender identities in Ireland in the nineteenth and twentieth centuries. Including but going beyond the binary of male and female heterosexual experience, the book explores LGBTQI+ histories, the treatment of intersex persons, and the history of trans people and activism in Ireland. As an interdisciplinary work, this reader draws together scholars working in a range of fields on innovative, new research on this theme.
