The impeachment of Andrew Johnson was a significant political event in 1868 where the 17th President of the United States faced charges brought by the House of Representatives, largely over his violation of the Tenure of Office Act. This situation arose during a tumultuous period of Reconstruction, reflecting the intense conflict between Johnson and Congress regarding how to handle the Reconstruction of the South following the Civil War. The impeachment highlighted the struggle over presidential power and congressional authority during a critical time in American history.
