How did the Nuremberg Trials promote justice on a worldwide scale?

The Nuremberg Trials were held for the purpose of bringing Nazi war criminals to justice, the Nuremberg trials were a series of 13 trials carried out in Nuremberg, Germany, between 1945 and 1949. The defendants, who included Nazi Party officials and high-ranking military officers along with German industrialists, lawyers and doctors, were indicted on such charges as crimes against peace and crimes against humanity. Nazi leader Adolf Hitler (1889-1945) committed suicide and was never brought to trial. Although the legal justifications for the trials and their procedural innovations were controversial at the time, the Nuremberg trials are now regarded as a milestone toward the establishment of a permanent international court, and an important precedent for dealing with later instances of genocide and other crimes against humanity.
