The Great War of 1914-1918 marked a turning point in modern history and culture. This Companion offers critical overviews of the major literary genres and social contexts that define the study of the literatures produced by World War I. It examines the war's impact on various national literatures before addressing the way the War affected Modernism, the European avant-garde, film, women's writing, memoirs, and, of course, the war poets. The volume concludes by addressing the legacy of the war for twentieth-century literature.
