First observed on 20 May 1950, Armed Forces Day was
created on 31 August 1949 as President Harry S. Truman
led the effort to establish a single holiday for citizens to
come together and thank military members for their
patriotic service in support of the republic and national
interests and as a undeniable fact of American life.
