The significance of the Nuremberg Trials lies in their establishment of accountability for war crimes and crimes against humanity following World War II. These trials represented the first time leaders were held legally accountable for such acts at an international level, setting important precedents in international law. The Nuremberg Trials underscored the principle that individuals, including heads of state, could be prosecuted for their actions during wartime. They helped shape the post-war order, promoting the idea of human rights and laying the groundwork for future international tribunals and the establishment of the International Criminal Court.
