World War I officially ended when the Treaty of Versailles was signed on June 28, 1919, outside the town of Versailles, France. Seven months prior, an armistice, or temporary cessation of hostilities, went into effect between the Allied nations and Germany on the eleventh hour of the eleventh day of the eleventh month. Today, and every Nov. 11, we celebrate this armistice, the end of World War I and all the brave men and women who vowed to protect our country.
