First it is essential to define Reconstruction especially from the Northern radicals point of view and from the Southern point of view (how did they differ)? Moreover, what were the Four phases/theories of Reconstruction? Who desired a particular theory and why, and what theory did they eventually settle on? How did Reconstruction in the end benefit the Freedmen (Blacks), or did it fail completely? if it failed, what replaced it? Be specific with pertinent data and legitimate sources.
