In this extensively illustrated book, an international team of experts explores the war in all its different aspects. From its causes to its consequences, from the Western Front to the Eastern, from the strategy of the politicians to the tactics of the generals, the course of the war is charted and its political and human consequences assessed. Chapters on economic mobilization, the impact on women, the role of propaganda, and the rise of socialism establish the wider social context of fighting which took place at sea and in the air and which ranged on land from the Flanders trenches to the Balkan mountains and the deserts of the Middle East.
