This Day in History: President Andrew Johnson Is Impeached February 24, 1868 Johnson assumed the presidency after Lincoln's assassination.
He became the first U.S. president to be impeached.
11 articles of impeachment were approved by the House of Representatives.
They arose from Johnson's unpopular and racist post-Civil War Reconstruction policies, and the firing of Lincoln appointed secretary of war, Edwin Stanton.
Johnson's Senate impeachment trial began on March 13.
He was not convicted, narrowly escaping removal from office.
