What were the Nuremberg trials of Nazi war criminals?

The Nuremberg Trials were 13 trials held in Nuremberg, Germany, after World War II. The first, held by an international tribunal (American, British, French, and Russian), was the "War Criminals" trial (to keep it simple, it was the trial of the "big names" in Nazism). It was followed by a series of 12 more trials held buy the United States: the Doctor's trial, the Milch trial, the Judge's trial (this is what the movie "Judgment at Nuremberg" was based on), the Pohl trial, the Flick trial, the I. G. Farbern trial, the Hostages trial, the RuSHA trial, the Einsatzgruppen trial, the Krupp trial, the Ministries trial and the High Command trial. The British and Polish also held their own trials.
