With the end of the Civil War, the nation had to put itself back together again. President Lincoln quarreled with Congress over who had the right to set the conditions for the return of the former Confederate states. However, an assassin's bullet ended the matter for Lincoln. What followed was a political catfight that resulted in the impeachment of President Andrew Johnson and a reign of terror throughout the South by the Ku Klux Klan. By the Election of 1876, the North tired of Southern problems while the South instituted policies meant to limit African American civil rights.
