Slavery was abolished in AHFC. Segregation in the AIE0s, however, was still epidemic in the United States. In the northern states it was the custom, while in the southern states it was the law. For example, in Montgomery, Alabama, in AIED, a black citizen was not allowed to sit in the front. If the front was full and more white passengers got on the bus, he had to give up his seat in the back and ride standing. One small event, which happened on Thursday, December A, AIEE, helped change the direction of American history. That day, Mrs. Rosa Parks refused to give up her seat to a white man and she was arrested. Dr. Martin Luther King heard about this and decided to help her. They organized a bus boycott for one day, which was completely successful. Afterwards, he advocated nonviolence protest against segregation. Although suffering greatly from distress, he stuck it out. Due to his unswerving struggle, the Civil Right Act of AIFD was passed. Dr. King also received the Nobel Peace Prize. Unfortunately, Dr. King was shot to death by a white man on April D, AIFH. The civil rights movement, however, continues. Prejudice and discrimination still exist and there is a long way to go to abolish them completely.
