Which phase of war did the Nuremberg Trials address regarding Nazi leaders?

The Nuremberg Trials were a series of military tribunals held after World War II to bring Nazi leaders to justice for their actions during the war. The primary focus of these trials was on war crimes accountability, as the defendants were charged with crimes against humanity, war crimes, and other offenses related to their roles in the Holocaust and aggressive warfare. The trials set significant legal precedents by establishing that individuals, including government officials, could be held accountable for their actions during wartime. These legal proceedings were pivotal in developing international law regarding war crimes and reaffirmed the principle that moral and ethical responsibility should be upheld even in wartime scenarios.
