The Nuremberg trials were used to put high-ranking Nazis for war crimes and atrocities they committed during WW2. (obviously the Allies performed war crimes as well, but they won the war so no one cared lol) They were held accountable for their crimes and most were sentenced to death. However, many former high-ranking Nazis were never found guilty and went on to lead their own lives, including many former generals helping with the formation of the post-war German Army (Bundeswehr) in 1955.
The crusades were considered a turning point in history because the pope urban 2 wanted the christians to fight the muslims so that they could have back the control over the holy lands
