Answer:
1960s.
Step-by-step explanation:
The Civil Rights Movement began around the 1940s and lasted till the 1960s. It was an organized protest and demonstration by the blacks in America fighting for their equal rights against the white majority power. Though the slavery system was ended, the prejudice and injustice against the blacks did not end with it. In name, the discrimination and the 'supposed' inferior treatment of the blacks ended but not in reality. They were still denied certain social equality, which led to this Civil Rights Movement. But this wasn't confined to the blacks only. Many whites also participated in this movement to demand equal rights for their black counterparts.
