The twentieth century was dominated by war and by preparations for war in a way that is unparalleled in history. Originally published in 1988, this textbook highlights key themes of warfare throughout the world and emphasizes the gulf between the theory of war and its practice.

The contributors are professional historians and strategists who consider the impact of war upon society, theories of insurgency and counter-insurgency and nuclear strategy, as well as more ‘traditional topics’ such as tactics and strategy on land, the role of sea power, the evolution of strategic bombing, colonial and revolutionary warfare. Each chapter discusses recent research on the topic and provides guides to further reading. Together they give a clear up-to-date overview of the conflicts which dominated the twentieth century.

This textbook is useful reading for all students and teachers of strategic and war studies, military history and international relations and for all those concerned with the study of major conflicts in the twentieth century.
