How would you explain the increasingly radical nature of congressional reconstruction?

The increasingly radical nature of congressional Reconstruction can be attributed to the growing frustration among Northern Republicans with the slow pace of change in the South and the persistent resistance from Southern Democrats. Following the Civil War, Congress sought to impose stricter measures to ensure civil rights and political participation for freed slaves, culminating in the passage of the Reconstruction Acts. The desire to protect these advancements and to prevent former Confederates from regaining power fueled more radical policies. Additionally, the assassination of President Lincoln and the rise of more militant leaders in Congress intensified the push for transformative reforms.
