Jim Crow law, in U.S. history, any of the laws that enforced racial segregation in the South between the end of Reconstruction in 1877 and the beginning of the civil rights movement in the 1950s.
Jim Crow was the name of a minstrel routine (actually Jump Jim Crow) performed beginning in 1828 by its author, Thomas Dartmouth (“Daddy”) Rice, and by many imitators, including actor Joseph Jefferson.
The term came to be a derogatory epithet for African Americans and a designation for their segregated life. Commons
