The Nuremberg trials were a series of military tribunals, held by the Allied forces after World War II, most notable for the prosecution of prominent members of the political, military, and economic leadership of Nazi Germany. The trials were held in the city of Nuremberg, Germany. The first, and best known of these trials, described as "the greatest trial in history" by Norman Birkett, one of the British judges who presided over it, was the trial of the major war criminals before the International Military Tribunal (IMT). Held between 20 November 1945 and 1 October 1946, the Tribunal was given the task of trying 23 of the most important political and military leaders of the Third Reich, though one of the defendants, Martin Bormann, was tried in absentia, while another, Robert Ley, committed suicide within a week of the trial's commencement. Not included were Adolf Hitler, Heinrich Himmler, and Joseph Goebbels, all of whom had committed suicide several months before the indictment was signed. The second set of trials of lesser war criminals was conducted under Control Council Law No. 10 at the U.S. Nuremberg Military Tribunals (NMT); among these included the Doctors' Trial and the Judges' Trial.
