Unify the country--bring blacks out of slavery--rebuild the South.
The country needed to be unified but also the Confederate leaders could not be included in the government of the Southern states. This effort meant new state constitutions and loyalty oaths to the US. With the 13th Amendment ending slavery, blacks needed to be eased out of slavery and into freedom. They needed assistance in gaining a job and economic security. Lastly, the South was torn apart by war and needed to be rebuilt. There was also a goal of building industry and putting in more rail lines and telegraphs to build the infrastructure of the South.
