Rewriting Gender in an Age of Transition: 1880–1940 examines shifting discourses on gender and sexuality across the fin-de-siècle and early twentieth century. This interdisciplinary collection challenges the conventional divide between the nineteenth and twentieth centuries, proposing instead that the period from 1880 to 1940 marks a pivotal era of transition. Through chapters spanning literature, history, art history, and linguistics, the volume explores evolving representations of femininity, masculinity, and queer identity in relation to broader cultural, political, and technological change. It places late nineteenth-century queer activism in dialogue with early twentieth-century media and artistic practices, revealing how anxieties around gender and sexuality shaped – and were shaped by – modernity. Contributions from both established and emerging scholars offer a multifaceted reappraisal of this transformative period. Rewriting Gender in an Age of Transition: 1880-1940 is ideal for students and researchers in gender studies, media studies, literature, history, and the social sciences interested in identity formation and cultural change.
