Black codes were laws that governed African Americans. However, Jim crows laws were state and local laws that enforced the segregation of African Americans and whites. So the difference would be that black codes didn’t include white people. Or, Jim Crow laws applied to blacks AND whites, while black codes only applied to blacks.
Black codes and Jim Crow laws were laws passed at different periods in the southern United States to enforce racial segregation and curtail the power of black voters.
