Book excerpt: This book tackles cultural mobilization in the First World War as a plural process of identity formation and de-formation. It explores eight different settings in which individuals, communities and conceptual paradigms were mobilized. Taking an interdisciplinary approach, it interrogates one of the most challenging facets of the history of the Great War, one that keeps raising key questions on the way cultures respond to times of crisis. Mobilization during the First World War was a major process of material and imaginative engagement unfolding on a military, economic, political and cultural level, and existing identities were dramatically challenged and questioned by the whirl of discourses and representations involved.
