We reviewed the reasons the U.S. joined the Allied fighting in WWI: 1) Germany's unrestricted submarine warfare, 2) the Russian Revolution. 3) Germany's sinking the Lusitania, 4) the Zimmermann Telegram. U.S. soldiers are in France by June, 1917. Led by Gen. John J. Pershing, the American Expeditionary Forces fortified the Allies. An armistice begins on Nov. 11, 1918. (It becomes a holiday - known as Armistice Day. Since WWII, it is now known as Veteran's Day.) Life in the U.S. involved mobilizing the entire nation for the war effort. War material production was overseen by the National War Labor Board. More labor was needed to produce these materials, providing jobs for women and minorities. We discussed the Food Administration, War Industries Board and rationing. What were the Great Migration from 1914-1920 and the Sabotage & Sedition Acts of 1918?
