In short: Following the Civil War, the United States briefly expanded rights for African Americans. Yet, by 1896, the Supreme Court’s Plessy v. Ferguson ruling enshrined the separate but equal doctrine, effectively legalizing Jim Crow. This era of systemic disenfranchisement and violence forced Black communities to build their own parallel economic worlds.

The period between 1896 and 1954 represents a stark reversal of the progress made during Reconstruction. While the 13th, 14th, and 15th Amendments initially granted citizenship and voting rights, the Compromise of 1877—which withdrew federal troops from the South—allowed white legislatures to systematically dismantle these gains. By the turn of the 20th century, Southern states had implemented poll taxes, literacy tests, and white-only primaries that effectively stripped over 95% of Black voters of their franchise. This political exclusion was reinforced by the Supreme Court, which in Plessy v. Ferguson (1896) and Williams v. Mississippi (1898) provided the legal scaffolding for state-mandated segregation and discriminatory voting restrictions.

The social consequences were profound. Jim Crow laws dictated every aspect of public life, from segregated schools and transportation to cemeteries and water fountains. Beyond legal barriers, Black citizens faced the constant threat of extrajudicial violence; thousands were lynched by vigilante mobs, often with the complicity of local officials. The criminal justice system was frequently weaponized through the convict-lease system, where Black men were imprisoned on minor charges and leased to private corporations for forced labor, creating a perverse financial incentive for mass incarceration.

Despite this oppression, the era saw the rise of what historian Juliet Walker termed the 'Golden age of black business.' Cut off from white-dominated markets, Black entrepreneurs built thriving, independent enterprises. Between 1900 and 1914, the number of Black-owned businesses doubled from 20,000 to 40,000. Figures like Madame C.J. Walker built national franchises, while local professionals—particularly undertakers—became pillars of political and community life. This resilience set the stage for the long legal and social battle that would eventually culminate in the 1954 Brown v. Board of Education decision, finally overturning the Plessy doctrine and beginning the slow, difficult process of dismantling the legal infrastructure of American apartheid.
