World War I was a major war centered in Europe that began in the summer of 1914 and lasted until November 1918. It involved all of the world’s great powers, which were assembled in two opposing alliances: the Allies and the Central Powers. More than 70 million military personnel, including 60 million Europeans, were mobilized in one of the largest wars in history. More than 9 million combatants were killed, largely because of great technological advances in firepower without corresponding advances in mobility.
