World War I ended on November 11, 1918, with the signing of the Armistice by the Allies and Germany. In the first Armistice Day proclamation in 1919, President Woodrow Wilson called for the nation to remember those who had died in their country's service and to make the day an opportunity for America to "show her sympathy with peace and justice in the councils of the nation."
In 1927 Congress called for the display of the U.S. flag on government buildings, and in 1938 Congress called for the observance of Armistice Day in churches and schools — again dedicating the day to the cause of world peace.
Note the order here: the nation was telling the churches to celebrate this day. This was not an initiative arising from the churches, but from Congress. The timing was significant. The strong stirrings of World War II had already begun in earnest in Europe. The United States was still reeling from the effects of World War I and the Great Depression, and the political climate overall was against any sort of engagement in wars.
Of course, within just three years, the United States became involved in the War "over there" in Europe and "way out there" in the Pacific.
Since the end of World War II, observances of Armistice Day have been held all over the nation, but especially in our national cemeteries and monuments and at the Tomb of the Unknown Soldier in Washington, D.C. The president and many state governors have issued proclamations. Countless communities, veterans groups, and civic clubs and organizations have held local observances. Armistice Day became Veterans' Day by an act of Congress in 1954, changing its purpose and scope. President Eisenhower called on the nation to remember the sacrifices of those who fought in all our nation's wars, to celebrate the contributions of all veterans of military service, and to rededicate ourselves to the task of promoting an enduring peace. It is Eisenhower's call that remains the three-fold purpose of Veterans' Day: remembering those who fought and died, celebrating all veterans, and promoting an enduring peace.
