Reconstruction in the South following the Civil War was a contentious period with competing plans over how to rebuild the former Confederate states. There were debates over granting rights to freed slaves, punishing Confederate leaders, and reintegrating the South into the Union. President Lincoln favored a lenient 10% plan for readmitting states, but he was assassinated in 1865. His successor, Andrew Johnson, took a harsher stance against the South. This led to conflicts with Radical Republicans in Congress who passed their own reconstruction plans over Johnson's veto. Reconstruction ultimately ended in 1877 after a compromise resolved a disputed presidential election. However, the end of federal oversight allowed Southern states to impose Jim Crow laws and disenfranchise black voters.
