Mississippi and other southern states followed the "Jim Crow" laws. In the states that followed the "Jim Crow" laws they were strictly enforced and people would be fined and imprisoned. In Mississippi, if anyone was caught promoting equality they could be fined up to $500.00 and/or be in jail 6 months in jail.
