Lincoln goals for civil war changed during the war, at the beginning the war was about preserving the union, but it later changed to ending slavery. This was clear during the Gettysburg Address, in this speech he talked about the principles of human equality and need to end slavery.
After slavery ended African Americans still had to face many problems, such as Black Codes that were laws that restricted legal rights to blacks, like the right to marry, own property and others.
Because of this, many African Americans used sharecropping that was a system of work that exchanged labor in return for housing, land and other commodities. Carpetbagger was a name that people called people who went south with cloth bags with goods from the north.
