“Jump Jim Crow” was the name of a minstrel routine originated about 1830 by Thomas Dartmouth (“Daddy”) Rice. He portrayed the Jim Crow character principally as a dim-witted buffoon, building on and heightening contemporary negative stereotypes of African Americans. “Jim Crow” came to be a derogatory term for Black people, and in the late 19th century it became the identifier for the laws that reinstated white supremacy in the American South after Reconstruction. The demeaning character symbolically rationalized segregation and the denial of equal opportunity.
