When most people think of Jim Crow they think of laws (not the Jim Crow etiquette) which excluded blacks from public transport and facilities, juries, jobs, and neighborhoods. The passage of the 13th, 14th, and 15th Amendments to the Constitution had granted blacks the same legal protections as whites.im Crow was the name of the racial caste system which operated primarily, but not exclusively in southern and border states, between 1877 and the mid-1960s.
Jim Crow laws were state and local laws enforcing racial segregation in the Southern United States. Enacted after the Reconstruction period, these laws continued in force until 1965.They mandated de jure racial segregation in all public facilities in states of the former Confederate States of America, starting in 1890 with a  separate but equal  status for African Americans.enerally, the remaining Jim Crow laws were overruled by the Civil Rights Act of 1964 and the Voting Rights Act of 1965, but years of action and court challenges were needed to unravel numerous means of institutional discrimination.
