The second World War greatly reshaped ideas about national identity in America, especially for first-generation immigrants, second-generation immigrants, and African-Americans. During the war - and in the midst of the war effort - immigrants and African-Americans were welcomed into the armed services and, also, in areas of production where support was needed.

Also, for immigrants and African-Americans, they often felt they were part of American industry and service for the first time.
