What is The difference between presidential reconstruction and radical reconstruction?

Presidential Reconstruction, led primarily by President Abraham Lincoln and continued by Andrew Johnson, focused on rapidly reintegrating the Southern states into the Union with lenient policies and minimal federal intervention. In contrast, Radical Reconstruction, driven by the Republican-controlled Congress, aimed to transform Southern society through more stringent measures, including civil rights protections for freedmen and military oversight of the South to ensure compliance with new laws. This difference in approach reflected varying views on how to rebuild the nation and address the rights of formerly enslaved individuals.
