What defense did former Nazis offer at the Nuremberg trials for theirs actions doing war?

At the Nuremberg Trials, many former Nazis claimed they were following orders from superiors, arguing that they were not personally responsible for their actions. This defense, known as the "Nuremberg defense," suggested that adhering to orders in a military hierarchy absolved them of moral responsibility. Some also argued that their actions were justified by the context of wartime and national duty. However, this defense was largely rejected by the tribunal, which emphasized individual accountability for war crimes.
