Who is group favored a much harsher reconstruction plan in south?

The Radical Republicans favored a much harsher Reconstruction plan for the South after the Civil War. They sought to impose strict measures on the Southern states, including the protection of African American civil rights and the redistribution of land. This group was driven by a desire to punish the South for its role in the war and to ensure that newly freed slaves would have equal rights and opportunities. Their approach led to significant political and social changes during the Reconstruction era.
