How far back does the celebration of verterans date?

The celebration of veterans dates back to the aftermath of World War I, specifically to November 11, 1919, when Armistice Day was first observed in the United States to honor those who served in the war. In 1954, after World War II and the Korean War, the day was officially renamed Veterans Day to recognize all American veterans. The commemoration has since evolved to honor the sacrifices and services of military personnel throughout history.
