A major work by our greatest military historian, acclaimed as the definitive history of the First World War, the conflict that shaped the twentieth century. The definitive account of the Great War and a national bestseller from eminent military historian John Keegan 2018 marks the centenary of the First World War - the war that created the modern world. It destroyed a century of relative peace and prosperity and saw a continent at the height of its success descend into slaughter. It unleashed both the demons of the twentieth century - political hatred, military destruction and mass death - and the ideas which continue to shape our world today: modernism in the arts, new approaches to psychology and medicine, and radical ideas about economics and society. By the end of the war, three great empires - the Austro-Hungarian, the Russian and the Ottoman - had collapsed. But as Keegan expertly shows, the devastation extended over the entirety over Europe and still profoundly informs the politics and culture of the continent today. Pertinent, authoritative and gripping, this panoramic account of WW1 is regarded as a world history classic. 'The best and most approachable introduction to the war' Guardian 'Nobody describes a battle as Keegan does, vividly relating the unfolding events to the contours of the field of combat... This book is a kind of war memorial. As first-hand memory fades, The First World War honours the dead as only true history can' Sunday Times
