World War I as a declared state of war lasted from July 28, 1914 to November 11, 1918. After a decade of unstable alliances and military buildups, World War I was triggered in 1914 by the assassination of Archduke Ferdinand. It ended in 1919 with the Treaty of Versailles. (See related question below.)
In 1918, on the eleventh hour of the eleventh day in the eleventh month, the world rejoiced and celebrated because after four years of bitter war, the Allied powers signed a cease-fire agreement (an armistice) with Germany at Rethondes, France on November 11, 1918. This brought World War I to a close.
