When did radical resonstruction end in the south?

Radical Reconstruction in the South effectively ended in 1877 with the withdrawal of federal troops following the Compromise of 1877. This compromise resolved the disputed 1876 presidential election and led to the end of Reconstruction policies, resulting in the restoration of white Democratic control in Southern states. The withdrawal marked a significant shift in the political landscape, leading to the implementation of Jim Crow laws and the disenfranchisement of Black voters.
