An armistice is an agreement between two or more parties to end hostilities. When the armistice for World War I was signed on November 11, 1918, the fighting stopped and the war was effectively over. The armistice called for the cessation of all hostilities by land, sea, and air within six hours of the signing of the agreement, and for the withdrawal of German troops from all occupied territories within two weeks. The armistice also set the stage for the negotiations that led to the signing of the Treaty of Versailles in 1919, which officially ended World War I and established the terms of peace.
