On December 7, 1941, following the Japanese bombing of Pearl Harbor, the United States declared war on Japan. Three days later, after Germany and Italy declared war on it, the United States became fully engaged in the Second World War.

U.S. involvement in the Second World War was quickly followed by a massive mobilization effort. With millions of men and women serving overseas in the nation's armed forces, most of those who remained at home dedicated themselves to supporting the war effort in whatever means was available to them. Women, who had worked as homemakers or had held jobs outside military-related industries, took jobs in aircraft manufacturing plants, munitions plants, military uniform production factories, and so on. As the need for steel and other resources increased, American citizens participated in rationing programs, as well as recycling and scrap metal drives. Americans also supported the war effort with their hard-earned dollars by purchasing Liberty bonds. Sold by the U.S. government, the bonds raised money for the war and helped the bond purchasers feel they were doing their part for the war effort.

The U.S. entry into the war helped to get the nation's economy back on its feet following the depression. Although just ten years earlier, jobs were very difficult to come by, there were now jobs for nearly everyone who wanted one. With the creation of 17 million new jobs during the war, workers were afforded the opportunity to pay off old debts, as well as to begin saving some of their earnings.

Not all Americans remaining at home gained favorably from the war. Fearing that Japan might invade the West Coast of the United States, the government rounded up thousands of Japanese Americans who lived on the West Coast, and confined them to internment camps. By 1948 when the internment program ended, tens of thousands of Japanese had suffered as internees. In addition, German Americans, Italian Americans, Hungarians, Romanians and Bulgarians were also interned.

On May 8, 1945, Germany surrendered. After the atomic bomb was dropped on Hiroshima and Nagasaki, Japan surrendered on September 2, 1945, and the Second World War came to an end. The war cost the lives of more than 330,000 American soldiers. Many more were permanently injured or maimed.

War broke out in Europe in the summer of 1914, with the Central Powers led by Germany and Austria-Hungary on one side and the Allied countries led by Britain, France, and Russia on the other. At the start of the war, President Woodrow Wilson declared that the United States would be neutral. However, that neutrality was tested and fiercely debated in the U.S.

Submarine warfare in the Atlantic kept tensions high, and Germany’s sinking of the British ocean liner Lusitania on May 7, 1915, killed more than 120 U.S. citizens and provoked outrage in the U.S. In 1917, Germany’s attacks on American ships and its attempts to meddle in U.S.-Mexican relations drew the U.S. into the war on the side of the Allies. The United States declared war on Germany on April 6, 1917.

Within a few months, thousands of U.S. men were being drafted into the military and sent to intensive training. Women, even many who had never worked outside the home before, took jobs in factories producing supplies needed for the war effort, as well as serving in ambulance corps and the American Red Cross at home and abroad. Children were enlisted to sell war bonds and plant victory gardens in support of the war effort.

The United States sent more than a million troops to Europe, where they encountered a war unlike any other—one waged in trenches and in the air, and one marked by the rise of such military technologies as the tank, the field telephone, and poison gas. At the same time, the war shaped the culture of the U.S. After an Armistice agreement ended the fighting on November 11, 1918, the postwar years saw a wave of civil rights activism for equal rights for African Americans, the passage of an amendment securing women’s right to vote, and a larger role in world affairs for the United States.

As you explore the primary sources in this group, look for evidence of the different roles U.S. citizens played in the war effort, as well as the effects of the war on the people of the United States.
