The fifth edition of International Relations covers the subject from the historical perspective—from the eve of the First World War to the end of the Cold War and beyond. This book is divided into two sections—the first deals with the theoretical perspectives, while the second provides an historical overview of events. These include the two World Wars, problems faced in peace-making, system of alliances, search for security, Nazism and Fascism, rise of communism, the arms race and disarmament, the Cold War and its end, Non-Aligned Movement, and the emergence of regional organizations. The book is a useful resource for teachers and students of history and political science, those appearing for civil services examinations, as well as those interested in international relations.
