The Second World War began to affect Americans long before the country was actually drawn into the fighting. Although the American nation stood on the sidelines for the first two years, America became a major source of money, supplies, and encouragement for Britain and France. Providing materiel for the Allies gave new life to the sagging American economy. There were still some five million unemployed in the nation, and something more seemed to be needed. Unfortunately for the Afro-American, most of the new jobs were not open to them. Aside from the fact that he was the first to be fired and the last to be hired, many of the new defense industries made it clear that they would hire no Negroes at all or, at most, would restrict their employment to janitorial positions regardless of the training or education of the applicant.

Hostility was expressed quite openly by some leaders in the West Coast aircraft industry. As better jobs became available, they were quickly filled by white workers eager to improve their economic status. This left some of the more undesirable jobs to go begging, and, as the result, the war boom benefits began to trickle down to the Afro-American community. Afro-Americans, however, were not content with the crumbs from the industrial table. Complaints began to flood into Washington. Several government officials made pronouncements condemning discrimination in defense industries, but they were not heard. It became clear that nothing would change without strong government action, and it was also evident that this would not occur unless the entire Afro-American community could exert united, political pressure.

Early in 1941, A. Philip Randolph put forth the idea of a gigantic March on Washington, and he expressed the belief that a hundred thousand Afro-Americans could be organized to participate in such an undertaking. The immediate response from most of the leaders of both black and white America was one of skepticism. Most of them felt that there was too much apathy in the Afro-American community for such a grandiose scheme to be taken seriously. Nevertheless, interest on the grass-roots level gradually grew and Randolph's idea was transformed into a project involving scores of organizers all across the country, all of whom were working diligently to enlist potential marchers. In the meantime, Randolph began to formulate the complex plans for organizing the actual march. By late spring, skepticism had turned to worry. Many government leaders and finally President Roosevelt himself tried to talk Randolph into canceling the march. They suggested that such an aggressive protest would do more to hurt the Afro-American than help him.

Randolph remained unyielding. Others tried to suggest that the protest would be bad for the American image and therefore was unpatriotic. When they suggested that it would create a bad impression in Rome and Berlin, Afro-Americans retorted that white racism had already created such an image. Finally, Roosevelt contacted Randolph and offered to issue an executive order barring discrimination in defense industries and promised to put "teeth" in the order, provided Randolph call off the march. When Randolph became convinced that Roosevelt's intentions were sincere, he complied.

Roosevelt fulfilled his promise by issuing Executive Order 8802, which condemned discrimination on the grounds of race, color, or creed. Then, he established the Fair Employment Practices Commission and assigned to it the responsibility for enforcing the order. Many Afro-Americans felt that Executive Order 8802 was the most important government document concerning the Negro to be issued since the Emancipation Proclamation. Their immediate joy was somewhat dampened when they found that discrimination still continued in some quarters. Nevertheless, the F.E.P.C. did condemn discrimination when it found it, and, as the result, many new jobs began to open up for Negroes.

Once America was drawn into the fighting, Afro-Americans hurried to the enlistment centers to volunteer their services in the war against Hitler's philosophy. However, it soon became clear that America intended to fight racism with a segregated army. The fact that Negroes were confined to the more menial positions in the armed forces was what irritated Afro-Americans the most. The Negro army units were obviously going to be led by white officers. The Marine Corps was still not accepting any Negroes in its ranks at all. Complaints again began to pour into Washington.

Afro-Americans generally admitted that the Selective Service Act per se was not discriminatory and that it was applied impartially in most places. One of the reasons for this impartiality, undoubtedly, was the fact that both local and national Selective Service Boards included Afro-American representation. In the course of the war, about one million Afro-Americans saw service on behalf of their country. Their ratio within the armed forces was almost the same as that within the nation. This had been the stated goal of the Department of War.

Gradually, the armed forces modified their discriminatory policies in response to the flood of complaints. The Air Force began to train Negro pilots although they still received segregated training and served in segregated squadrons. The Marine Corps accepted Negro recruits for the first time in its history. They, too, served in segregated units. The Navy, which had restricted Negroes to menial positions, gradually began to accept them in almost all noncommissioned positions. Eventually, it even began to commission some Negro officers. The Army, too, introduced an extensive program to prepare Negro officers. It trained most of them in integrated facilities, but they continued to lead segregated units. As the war grew to a close, the Army announced that it intended to experiment with integration. However, when the experiment took place, the integration proved not to be quite what had been expected. Instead of putting individuals from both races together in the same unit, the Army took segregated black and white platoons and merged them into an integrated fighting force although the platoons themselves remained segregated.

This integrated unit did fight well in the field and made a significant contribution to the defeat of Germany in 1945. Negro units, as well as individual Negro soldiers, made outstanding contributions to the war effort both in Europe and in the Pacific, and they received numerous commendations and citations. Skeptics noted, however, that not a single Negro soldier had received the Congressional Medal of Honor in either the First or Second World Wars, and they suggested that the nation's highest award was being reserved for whites.

Although most of the hostilities were focused on the enemy, racial tensions still ran very high within America. Southern whites were displeased with the self-confidence and manliness brought out in Negroes by military experience, and they were unhappy with the dignity which a military uniform conferred upon them.
