Sean O'Casey is one of Ireland's best-known writers. He is the most frequently performed playwright in the history of the Irish National Theatre, and his work is often revived onstage elsewhere. O'Casey is also widely studied in schools, colleges, and universities in the English-speaking world. This book offers a new contextualisation of this famous writer's work, revisiting his association with Irish nationalism, historical revisionism, and celebrated contemporaries such as W. B. Yeats and Lady Gregory. The volume also brings O'Casey's work into contact with topics including disability studies, gender and sexuality, post-colonialism, ecocriticism, and race. Sean O'Casey in Context explores a number of existing ideas about O'Casey in the light of new academic developments, and updates our understanding of this important writer by taking into account recent scholarly thinking and a range of theatrical productions from around the globe.
