Jim Crow etiquette operated in conjunction with Jim Crow laws (black codes). 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. However, after 1877, and the election of Republican Rutherford B. Hayes, southern and border states began restricting the liberties of blacks. Unfortunately for blacks, the Supreme Court helped undermine the Constitutional protections of blacks with the infamous Plessy v. Ferguson (1896) case, which legitimized Jim Crow laws and the Jim Crow way of life.
