After the passage of the 13th, 14th, and 15th Amendments, African Americans continued to face political and economic oppression due to systemic racism and discriminatory practices such as Jim Crow laws, which enforced racial segregation. Additionally, mechanisms like literacy tests, poll taxes, and intimidation tactics were implemented to disenfranchise Black voters. Economic oppression persisted through sharecropping and exploitative labor practices that kept African Americans in poverty and limited their economic mobility. These ongoing injustices reflected deeply entrenched societal attitudes that resisted true equality despite constitutional protections.
