The Civil Rights movement, begun to end racial discrimination in America, had raised awareness of many other kinds of discrimination in the educational system, employment, and housing, and in the military forces where racial segregation both of the African Americans and the Japanese Americans had forced them into concentration camps on doubts of their patriotism. These movements raised questions of many other forms of discrimination, such as when women were forced to give up their war time jobs as men returned from the battlefields.
