Explanation: Jim Crow era began when state laws were enacted for the southern states of the United States of America. These measures defined that public schools and most public places (including trains and buses) had different facilities for whites and blacks. Jim Crow's laws were in force between 1876 and 1965 and were opposed by several groups, including the National Association for Advancing of Colored People (NAACP), a key body in ending segregation.
