The Jim Crow Laws enforced racial segregation and discrimination in the Southern United States between the late 19th century and mid-20th century. They originated after the Reconstruction Era ended in 1877 and Democrats regained control of Southern state legislatures. The laws were named after a popular minstrel show song and restricted African Americans to separate public facilities under the doctrine of "separate but equal." It was not until the Civil Rights Movement in the 1950s and 1960s that the Jim Crow laws were challenged and eventually abolished.
