Lincoln went disgustingly soft on reconstruction, Johnson destroyed it.
Honestly Lincoln cared far more about getting the country together than he did about ending slavery, or attempting to integrate these new freed persons into society. Several times he seriously suggested sending them off to some island to colonize it themselves so he wouldn’t have to deal with it.
Also I’d highly encourage anyone to read “Black Reconstruction in America” by Dr. W.E.B. DuBois if you’re interested in this kind of thing.
