The idea of using American Indians who were fluent in both their traditional tribal language and in English to send secret messages in battle was first put to the test in World War I with the Choctaw Telephone Squad and other Native communications experts and messengers. However, it wasn’t until World War II that the US military developed a specific policy to recruit and train American Indian speakers to become code talkers.

During World War II, African Americans made tremendous sacrifices in an effort to trade military service and wartime support for measurable social, political, and economic gains. As never before, local black communities throughout the nation participated enthusiastically in wartime programs while intensifying their demands for social progress.

When we think of World War II, the first images that enter our minds usually involve battle: armies fighting their desperate struggles on land, huge navies patrolling the oceans, and aircraft soaring sleekly overhead.

From our 21st-century point of view, it is hard to imagine World War II without the United States as a major participant. Before the Japanese attack on Pearl Harbor in 1941, however, Americans were seriously divided over what the role of the United States in the war should be, or if it should even have a role at all. Even as the war consumed large portions of Europe and Asia in the late 1930s and early 1940s, there was no clear consensus on how the United States should respond.

In January of 1941, President Franklin Delano Roosevelt outlined a vision of the future in which people the world over could enjoy four essential freedoms. This vision persisted throughout World War II and came to symbolize the ideals behind the rights of humanity and the pursuit of peace in a postwar world.

The United States was not the only leading power on the world stage after the end of World War II; it had a new competitor for this power in the Soviet Union. Tensions between the former allies quickly grew, leading to a new kind of conflict—one heightened with the threat of atomic weapons—that came to dominate global politics for the remainder of the twentieth century.

One of Japan’s main goals during World War II was to remove the United States as a Pacific power in order to gain territory in east Asia and the southwest Pacific islands. Japan hoped to defeat the US Pacific Fleet and use Midway as a base to attack Pearl Harbor, securing dominance in the region and then forcing a negotiated peace. 
 

In World War II, the three great Allied powers—Great Britain, the United States, and the Soviet Union—formed a Grand Alliance that was the key to victory. But the alliance partners did not share common political aims, and did not always agree on how the war should be fought.

After the US strategic victories at the Battles of the Coral Sea (May 7–8, 1942) and Midway (June 4–7, 1942), the Japanese Imperial Navy was no longer capable of major offensive campaigns, which permitted the Allies to start their own offensive in the Pacific.

“It was too much death to contemplate, too much savagery and suffering; and in August 1945 no one was counting. For those who had seen the face of battle and been in the camps and under the bombs—and had lived—there was a sense of immense relief.”

Wartime needs increased labor demands for both male and female workers, heightened domestic hardships and responsibilities, and intensified pressures for Americans to conform to social and cultural norms.

At the time of the Japanese attack on Pearl Harbor in 1941, about 120,000 persons of Japanese ancestry lived on the US mainland, mostly along the Pacific Coast. About two thirds were full citizens, born and raised in the United States. Following the Pearl Harbor attack, however, a wave of antiJapanese suspicion and fear led the Roosevelt administration to adopt a drastic policy toward these residents, alien and citizen alike.
