The three groups that supported Radical Reconstruction are:
- Newly freed African Americans - They sought rights and opportunities following the Civil War.
- Scalawags - These were white Southerners who supported the Reconstruction efforts and aligned themselves with the Republican Party.
- Businesspeople interested in rebuilding - Many business leaders supported Reconstruction as a means to expand the economy and develop the South after the war.
Rich, white landowners generally opposed Radical Reconstruction, as it threatened their economic and social dominance.
