Calls for reparations for slavery date to the post-Civil War era ("forty acres and a mule"). The modern federal proposal, H.R. 40, would establish a commission to study the impacts of slavery and discrimination and propose remedies; it has been introduced in every Congress since 1989 without passage.
The empirical case rests on a long historical record: slavery, post-Reconstruction violence and disenfranchisement, Jim Crow, the GI Bill's racial exclusions, redlining and housing-policy harms, and persistent racial wealth gaps that economic studies tie at least in part to these histories.
Several states (notably California) and cities (Evanston, IL; San Francisco) have studied or implemented localized reparations programs. Federal action has not advanced. The debate spans moral philosophy, history, economics, and political feasibility.
