November 8, 1864
Lincoln reelected
Following decisive Union victories by Admiral Farragut in Alabama and General Sherman in Atlanta, Abraham Lincoln is reelected as President of the United States, with Andrew Johnson as his vice president. Along with 55 percent of the popular vote, Lincoln wins 212 electoral votes to McClellan's 21.
With Lincoln's influence, the House of Representatives approves the Thirteenth Amendment, which calls for the emancipation of all slaves and no compensation to their owners. The amendment was passed by the Senate in 1864 but failed to receive the necessary votes in the House. By December of 1865, enough states ratify the amendment to make it constitutionally binding.
