The first Nuremberg trial (formally known as the International Military Tribunal) was convened November 20, 1945, in Nuremberg, Germany, to try more than 20 high Nazi officials, including 4 members of the Armed Forces High Command. The verdict was rendered October 1, 1946. Legal teams from each of the four allied nations — the United States, Great Britian, Soviet Union, France — shared responsibility for the prosecution.
Hitler and two of his most notorious henchmen, Goebbels and Himmler, had committed suicide before V-E Day, May 8, 1945. But the Allies indicted 24 other Nazi leaders, of whom 23 were arrested and brought to trial at Nuremberg. Martin Bormann was thought to be still at large when the proceedings began, and was tried in absentia.
Before the trial began, it was decided that the industrialist Gustav Krupp von Bohlen und Halbach was too weak to stand trial. Shortly before the start of the trial, Dr. Robert Ley managed to hang himself in his Nuremberg cell.
That left 21 defendants in the dock at Nuremberg.
