America during the Second World War, 1941-1945
With the surprise Japanese air attack on the United States Naval Base at Pearl Harbor, Hawaii, in 1941, America's isolationist stance in the Second World War came to a sudden and dramatic end. Over the next four years, the US fought a two-front war in Europe and the Pacific alongside the other Allied powers. In addition to political and military developments, America's involvement in the war also brought important changes on the domestic front, with Americans from all walks of life becoming involved in one way or another. Women joined the American workforce in record numbers, taking over jobs normally held by the men who were now at war, creating the enduring 'Rosie the Riveter' image. Women also participated actively in the war by joining special military units, as did African-Americans. At the same time, German- and Japanese-Americans faced discrimination and the government established internment camps for the confinement of Japanese-Americans. The tide of the war turned in favour of the Allies after the Normandy landings on D-Day, and the use of the atomic bomb on Hiroshima and Nagasaki brought an end to the conflict.
