World War I, also called First World War or Great War, an international conflict that in 1914–18 embroiled most of the nations of Europe along with Russia, the United States, the Middle East, and other regions. The war pitted the Central Powers—mainly Germany, Austria-Hungary, and Turkey—against the Allies—mainly France, Great Britain, Russia, Italy, Japan, and, from 1917, the United States. It ended with the defeat of the Central Powers. The war was virtually unprecedented in the slaughter, carnage, and destruction it caused.
World War I was one of the great watersheds of 20th-century geopolitical history.

His poetry is remembered for the satirical edge of its criticism of the military high command and disdain for unquestioning patriotism, with the anger and indignation present in much of his verse characteristic of many men who served in the trenches.
