The Great War was fought from 1914 to 1918, and was officially ended in 1919 by the Treaty of Versailles. Its primary locus was the trench war on the Western Front between the Entente Powers (the British, French, and Russian empires, the US from 1917, and many other nations) and the Central Powers (the German, Austro-Hungarian, and Ottoman empires and Bulgaria). By the time the armistice was signed at Compiègne, at 11 a.m on November 11, 1918, almost nine million combatants had been killed. It was the first truly global war, whose modernity was felt in its scale, technology, and the corresponding speed with which events could be reported. The impact of the war was unavoidable in Europe and was felt in literature at the levels of content and form, in modernist prose and poetry, by men and women, combatants and civilians.
