Mosaic Fictions is the first book-length critical analysis of Canadian Spanish Civil War literature. Exploring published and archival writings, the book focuses on the extensive contributions of Jewish Canadian authors as they articulate the stakes of the Spanish Civil War (1936–9) in the language of a nascent North American multiculturalism. Placing Jewish Canadian writers within overlapping North American networks of Jewish, Black, immigrant, female, and queer writers challenges the national distinctions that dominate current critical approaches to Anglophone Spanish Civil War literature. Reframing the narrative of Spain’s noble but tragic struggle against fascism in the Spanish Civil War, the book demonstrates how marginalized North American supporters of the Spanish Republic crafted narratives of inclusive citizenship amidst a national crisis not entirely their own. Mosaic Fictions examines texts composed between the war’s outbreak and the present to illuminate the integral connections between Canada’s developing national identity and global leftist action.
