<span>Mobilization of the American Home Front
World War II officially began in Europe when Germany invaded Poland in 1939. By 1940 the war in Europe was in full swing, and the Allies, the nations fighting Germany and Italy, including Britain and France, needed U.S. support. At this time the United States was not involved in the war. However, it did agree to provide the Allies with weapons and other war materials. This agreement changed daily life in the United States as Americans began participating in a broad united effort to support the far-off military campaign. The biggest challenge involved industrial mobilization, the conversion of U.S. manufacturing from the production of civilian goods to the production of war materials. America had much to do to gear up for war production. It had to awaken from an economic lull brought on by the Great Depression. The Great Depression was the most severe economic crisis the United States ever experienced. It began in late 1929 and lasted throughout the 1930s. The Depression led to slowed business activity, high unemployment rates, and social unrest in many areas of the country.
To guide and coordinate the massive mobilization effort the U.S. government created numerous temporary federal agencies, including the War Resources Board, Office of Emergency Management, Office of Production Management, Supplies Priorities and Allocations Board, War Production Board, Office of Economic Stabilization, Defense Plant Corporation, and Office of War Mobilization. Under the guidance of these agencies, American businesses and workers brought about a giant increase in U.S. industrial productivity, and overall the mobilization effort created dramatic growth in large private corporations.</span>
