The document summarizes the end of Reconstruction and the rise of Jim Crow laws in the Southern United States after the Civil War. It explains that after Reconstruction ended in 1877, without federal protection, African Americans lost many rights and freedoms. Southern states then began passing Jim Crow laws that legalized racial segregation and discrimination, denying African Americans equal access to public spaces, education, jobs, voting rights, and more. This led to the widespread oppression and disenfranchisement of African Americans under an entrenched system of racial segregation in the South for the next 70+ years.
