Whatever might have been the disposition of the Northern politicians toward Lincoln's movements for Southern reinstatement, when it was undertaken by Andrew Johnson, it created such a state of fury and hate that his impeachment and expulsion from office was immediately attempted by Congress. In a trial of impeachment a committee from the House of Representatives makes the accusations, while the Senate sitting as a court under the presidency of the Chief Justice, hears the evidence and votes upon the guilt or innocence of the accused. A two-thirds vote is required to convict, and in this case one vote was lacking to secure conviction.

One of these expedients was to try Jefferson Davis for treason and to condemn him to death and execute him.
