The exhibition The World at War, 1914-1918 marks the centenary of the start of World War I. Once thought to be "the war to end war," such naïve optimism was quickly shattered by the experience of civilian and soldier thrust into the shared horror of industrial warfare. The war lasted four long years and killed ten million people. Wilfred Owen eulogized those killed in battle as "our undying dead." Siegfried Sassoon called them "the nameless names." And Gertrude Stein famously pronounced the casualties as well as the survivors of the war the "Lost Generation," whose world view had been changed forever. The geopolitical causes, the war's global expansion, and the outcomes of the war are well documented. The collective personal and national trauma inflicted on all who experienced the war, however, remains a potent touchstone that speaks to a contemporary world still embroiled in conflict. Drawing on the Ransom Center's extensive cultural collections, this exhibition and companion publication illuminate the lived experience of the war from the point of view of its participants and observers, preserved for a twenty-first-century generation through letters, drafts, and diaries; memoirs and novels; photographs and works produced by battlefield artists; and propaganda posters and films.
