Tracking the evolutionary arc of prison writing across the twentieth century in an international and comparative framework, this study proposes an integrated account of the major shifts and movements in this relatively neglected genre of autobiography. Dwelling on works—memoirs, novellas, poems—by actual detainees, the book offers a close stylistic analysis of 12 important texts to show how prison writing moved away from the confessional and self-scrutinizing modes of an earlier tradition, to espouse openly political sentiments and solidarities. Looking at works by Oscar Wilde, Rosa Luxemburg, Ezra Pound, Primo Levi, Bobby Sands, Angela Davis, Ngũgĩ wa Thiong’o, and Behrouz Boochani (among others), the book shows how themes such as the annihilation of experience, dehumanization, sensory deprivation, brutality, and numbing routine are woven into distinctive textual artefacts that give evidence of an abiding human resilience in the face of raw state power.
