Reconstruction faced many challenges including how to rebuild the South after the Civil War, integrate freed black people, and determine the appropriate level of federal oversight. There were competing plans between Presidents Lincoln and Johnson and Congress, with Congress favoring more protections for black civil and voting rights through military occupation and constitutional amendments. However, the withdrawal of federal troops from the South in 1877 due to political deals marked the end of Reconstruction and freed southern states to impose Jim Crow laws discriminating against black citizens.
