The Nuremberg Trials established the significant legal principle of accountability for war crimes, crimes against humanity, and genocide. Held after World War II, these military tribunals prosecuted Nazi leaders for their roles in atrocities committed during the Holocaust and the war. The trials set a precedent for international law, asserting that individuals, including heads of state, could be held accountable for actions that violate human rights. They underscored the importance of justice and fairness in addressing egregious acts, contributing to the development of international treaties and institutions focused on human rights protections and the legal mechanism for prosecuting war crimes globally.
