In Conflict, Diaspora, and Empire: Irish Nationalism in Britain, 1912–1922, Darragh Gannon investigates the development of Irish nationalism in Britain over the course of constitutional crisis, war, and revolution in the early twentieth century. The book has three overarching objectives: it aims to investigate the significance of the Irish in Britain during the Irish Revolution, identify the influences of overlapping contemporary themes, and establish the impact of Edwardian, World War I, and postwar culture on Irish nationalism in Britain. The result is a fascinating study of a complex community who were both molded by British society, and deeply connected by the conflicts and cultures across the Irish Sea.
