The three groups that supported Radical Reconstruction are:
- Newly freed African Americans - They sought to gain rights and improve their social and economic status following emancipation.
- Scalawags - This term referred to white Southerners who supported Radical Reconstruction and the Republican Party.
- Businesspeople interested in rebuilding - Some businesspeople supported Radical Reconstruction as a way to foster economic growth and development in the South after the Civil War.
Rich, white landowners generally resisted Radical Reconstruction, as it threatened their socio-economic status and traditional power structures.
