What were jim crow laws and how were they applied?

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 Blacks.
