Jim Crow Law

Laws that discriminated against black Americans by requiring segregation -- for example, in public schools, public places, and public transportation. "Jim Crow" was a derogatory term for black Americans, most likely derived from "Jump Jim Crow," a caricature performed in blackface as early as 1832. Jim Crow laws were declared unconstitutional and put to an end during the Civil Rights Movement in the 1960s.
