The focus of the Nuremberg Trials after World War II was to hold Nazi war criminals accountable for their actions during the Holocaust and other war crimes. The trials began in 1945 and aimed to prosecute key leaders of the Third Reich for crimes against humanity, genocide, and violations of international law. The trials established important precedents in international law, emphasizing the principle that individuals, including state leaders, could be held criminally responsible for their actions. The Nuremberg Trials played a crucial role in addressing the atrocities of the Holocaust and sought to promote justice and prevent similar crimes in the future.
