The Encyclopedia of World War I: A Political, Social, and Military History treats its monumental subject with the scope and insight it deserves. Its lavishly illustrated volumes, produced by an international team of experts, offer a deeper, more richly researched presentation of the battles, campaigns, and weapons technologies of the Great War than any previous work.

The encyclopedia also ranges well beyond the day-to-day battlefield struggles to capture the whole impact of the war, offering in-depth portraits of historic figures, everyday soldiers, and civilians on all home fronts. It provides the latest thinking from experts around the world on the war's buildup (the Anglo-German naval arms race), legacy (the Russian Revolution and Civil War, the Red Scare in the United States), and unresolved questions such as the ultimate responsibility for the war. With over 1,200 entries (over one million words), plus a volume of primary documents, The Encyclopedia of World War I is the definitive scholarly reference on a struggle whose aftershocks are still being felt.
