After World War II ended, twenty-two of the most powerful Nazi officials who were not killed-in-action or who did not commit suicide were put on the first international trial recorded in history. Twelve of the accused men were given the death penalty, and the other ten were sentenced to time in prison. This was a very important event because it was the beginning of an international court system that held court for three different kinds of crime: Crime against Peace, War Crime, and Crimes against Humanity. These trials also led to the formation of the United Nations Genocide convention and Universal Declaration for Human Rights and war Customs convention.
