Which president was impeached during the aftermath of the Tenure of Office Act?

Andrew Johnson was the president impeached during the aftermath of the Tenure of Office Act, which was a significant piece of legislation passed in 1867. This act aimed to restrict the president's power to remove certain officeholders without the Senate's approval. Johnson's impeachment stemmed from his violation of this act when he attempted to dismiss Edwin M. Stanton, the Secretary of War, which was seen as a direct challenge to congressional authority.

The context surrounding Johnson's impeachment involves a broader struggle between the presidency and Congress during the Reconstruction era following the Civil War. Although the Senate ultimately acquitted Johnson, the impeachment proceedings established important precedents regarding the limits of presidential power and the role of Congress in overseeing executive actions. This event is often discussed within the framework of checks and balances in the U.S. government.
