The global impact of the First World War dominated the history of the first half of the twentieth century. This major reassessment of the origins of the war, based on extensive original research in several countries, is the first full analysis of the politics of armaments in pre-1914 Europe.David Stevenson directs attention away from the Anglo-German naval race towards the competition on land between the continental armies. He analyses the defence policies of the Powers, and the interaction between the growth of military preparedness and the diplomatic crises in the Mediterranean andthe Balkans that culminated in the events of July-August 1914. The thought-provoking conclusions about the relationship between armaments and international conflict offer a fresh conceptual framework for the study of the origins of the First World War.
