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.
(These Jim Crow Laws were separate from the 1800-66 Black Codes, which had restricted the civil rights and civil liberties of African Americans.) State-sponsored school segregation was declared unconstitutional by the Supreme Court of the United States in 1954 in Brown v. Board of Education.enerally, the remaining Jim Crow laws were overruled by the Civil Rights Act of 1964 and the Voting Rights Act; none were in effect at the end of the 1960s.
