Book excerpt: In a new interpretation of the history of the Balkans during the Second World War, Alfred J. Rieber explores the tangled political rivalries, cultural clashes, and armed conflicts among the great powers and the indigenous people competing for influence and domination. The study takes an original approach to the region based on the geography, social conditions, and imperial rivalries that spans several centuries, culminating in three wars during the first half of the twentieth century. Against this background, Rieber focuses on leadership - personified by Mussolini, Hitler, Stalin, Churchill, and Tito - as the key to explaining events.
