When were Jim crow laws passed?
Jim Crow laws were laws that were passed in the south after the civil war that separated white and black people in public and private facilities. Laws like this lost African Americans their voting rights in Southern states. It got its name from a minstrel-show character who sang a comic song ending in the words, "Jump, Jim Crow."
Jim Crow did not create the laws. He was a black man who was singing a song while working when a white man heard his song and wrote his own song called the Jim crow jubilee. It was a major hit so when the segregation laws came out they just used his name. Its a name thing like plessy vs Ferguson but Jim crow had nothing to do with the laws.
