Now in its fifth edition, The Origins of the Second World War explores the reasons why the Second World War broke out in September 1939 and why a European conflict developed into a war that spanned the globe.

This book argues that the global conflict was not just ‘Hitler’s War’ but one that had its roots and origins in the decline of the old empires of Britain and France and the rise of ambitious new powers in Germany, Italy and Japan who wanted large empires of their own. Richard Overy covers the origins of the war from its background in the First World War to its expansion to embrace the Soviet Union, Japan and the United States by the end of 1941. Creating a comprehensive and analytical narrative while remaining a succinct overview of the subject, this book takes a thematic approach to the complex range of events that culminated in global warfare, discussing factors such as economic rivalry, rearmament and domestic politics and emphasizing that any explanation of the outbreak of hostilities must be global in scope. This new edition includes more discussion of the role of empire and the imperial background to the war.

Containing several new primary source documents alongside a glossary, a chronology of key events and a who’s who of important figures, this book is an invaluable introduction for any student of this fascinating period in history.
