"the Fourth World War"

When war engulfed Europe in 1914, the conflict quickly took on global dimensions. Although fighting erupted in Africa and Asia, the Great War primarily pulled troops from around the world into Europe and the Ottoman Empire. Amid the fighting were large numbers of expeditionary forces—and yet they have remained largely unstudied as a collective phenomenon, along with the term “expeditionary force” itself.

The First World War, now a century ago, still shapes the world in which we live, and its legacy lives on, in poetry, in prose, in collective memory and political culture. By the time the war ended in 1918, millions lay dead. Three major empires lay shattered by defeat, those of Germany, Austria-Hungary, and the Ottomans. A fourth, Russia, was in the throes of a revolution that helped define the rest of the twentieth century.
