How many Nuremberg trials were held?

There was only one 'TRUE' Nuremberg Trial, it was operating from November 1945 to October 1946. The trial was of 22 German principals which was made up of a mixture Generals, and Politicians, who where not fast enough to escape on the Odessa SS escape line, and so were in Allied hands.

I said above, only one 'TRUE' Trial, because there were a number of other trials held during that time, and afterwards, but these were for, so called, minor persons, both male and female, who were captured, and placed on trial for War Crimes against humanity, and though one or two were hung, most were given sentences ranging from one to five years, and most were let out after a short time.
