How was the federal government affected by the Radical Reconstruction period?

During the Radical Reconstruction period (1867-1877), the federal government significantly increased its role in Southern states, enforcing civil rights protections and overseeing the integration of formerly enslaved people into society. This led to the establishment of the Freedmen's Bureau and the passage of the Reconstruction Amendments (13th, 14th, and 15th), which aimed to secure citizenship and voting rights for African Americans. Tensions arose between Congress and President Andrew Johnson, ultimately leading to Johnson's impeachment and a shift in power towards a more assertive Congress. The federal government thus became a key player in reshaping Southern society and addressing the legacies of slavery.
