The events of World War II set the stage for the rise of modern civil rights movement thru the shortage of white male laborers which was caused by the early 1940s demand for soldiers. This labor shortage made new job opportunities available for Latinos, African Americans and white women.
The discriminatory policies ended since around 1 million African Americans served in the army, wherein the military needed a lot of fighting men. In the past, this policy did not allow African Americans from serving in the fighting unit.
