What happened when federal troops left the South in 1877?

• A. Northern control increased
• B. Civil rights protections expanded
• C. Federal protection weakened, emboldening white supremacist regimes
• D. Reconstruction gains were accelerated

Answer: (C)

When federal troops leave the South in 1877, federal protection for the rights of Black citizens and the enforcement of Reconstruction laws collapse. The military presence had been the mechanism shielding African Americans from violence and supporting Republican governments in the region. Once that protection is withdrawn, white supremacist groups and Redeemer governments can consolidate power, roll back civil rights, and effectively disenfranchise Black voters. This marks a sharp reversal of Reconstruction gains and the end of federal efforts to平 enforce equal rights in the South for decades. The other options don’t fit because Northern control does not increase, federal protections do not expand, and Reconstruction gains are not accelerated; they erode as Southern states reassert local control.
