Andrew Johnson (December 29, 1808 – July 31, 1875) was the 16th Vice-President and 17th President of the United States. He was the first president to be impeached, but he was not removed from office. The impeachment happened because he fired the Secretary of War after Congress had made it illegal. This was also considered strange, as it is usually up to the president to appoint and fire his secretaries. However, Congress disliked him because he was a Democrat and did not want to help former slaves.
