On the 11th hour of the 11th day of the 11th month of 1918, an armistice, or temporary cessation of hostilities, was declared between the Allied nations and Germany in the First World War, then known as “The Great War.”
Commemorated as Armistice Day beginning the following year, November 11th became a legal federal holiday in the United States in 1938. In the aftermath of World War II and the Korean War, Armistice Day became Veterans Day, a holiday dedicated to American veterans of all wars.
On June 4, 1926, Congress passed a resolution that the “recurring anniversary of [November 11, 1918] should be commemorated with Thanksgiving and prayer and exercises designed to perpetuate peace through good will and mutual understanding between nations” and that the president should issue an annual proclamation calling for the observance of Armistice Day. By that time, 27 state legislatures had made November 11 a legal holiday. An act approved May 13, 1938 made November 11 a legal Federal holiday, “dedicated to the cause of world peace and to be hereafter celebrated and known as ‘Armistice Day.’” In actuality, there are no U.S. national holidays because the states retain the right to designate their own, and the government can only designate holidays for federal employees and for the District of Columbia. In practice, however, states almost always follow the federal lead.
