<P> World War I ( often abbreviated as WWI or WW1 ) , also known as the First World War or the Great War , was a global war originating in Europe that lasted from 28 July 1914 to 11 November 1918 . Contemporaneously described as the `` war to end all wars '' , it led to the mobilization of more than 70 million military personnel , including 60 million Europeans , making it one of the largest wars in history . An estimated nine million combatants and seven million civilians died as a direct result of the war , while it is also considered a contributory factor in a number of genocides and the 1918 influenza epidemic , which caused between 50 and 100 million deaths worldwide . Military losses were exacerbated by new technological and industrial developments and the tactical stalemate caused by grueling trench warfare . It was one of the deadliest conflicts in history and precipitated major political changes , including the Revolutions of 1917 -- 1923 , in many of the nations involved . Unresolved rivalries at the end of the conflict contributed to the start of the Second World War about twenty years later . </P>
