The First World War was a watershed in world history. Tragic but far from futile, its origins, events and legacy have roused impassioned debate, creating multiple interpretations and confusion for those encountering the period for the first time. Synthesising the latest scholarship, acclaimed historian Gary Sheffield cuts to the heart of the conflict. He explores such key issues as: - the causes of war- the great battles on land, sea and in the air- the search for the peace and peace settlements- the political, social and economic consequences- the impact of 'total war' on the belligerents and the individual- and the place of the Great War in the history of warfare  Accessible and authoritative, this is the ultimate introduction for anyone wanting a clear understanding of what happened and why.
