This book investigates architecture as a form of diplomacy in the context of the Second World War at six major European international and national expositions that took place between 1937 and ’59. The volume gives a fascinating account of architecture assuming the role of the carrier of war-related messages, some of them camouflaged while others quite frank. The book provides a novel assessment of modern architecture’s involvement with national representation it also argues that this widespread confidence in architecture’s ability to act as a propaganda tool was one of the reasons why Modernist architecture lent itself to the service of such different masters.
