In 1945, on the ninth day of testimony at the Nuremberg Trials, the prosecutors introduced a damning piece of evidence - a film that showed the gas chambers at Dachau. Nineteen Nazi war criminals were convicted, and the Nuremberg Trials helped establish an international system of criminal law that included the adoption of the Genocide Convention.
The Genocide Convention has some of the strongest protections under the law for victims, but its effectiveness rests on states fulfilling their obligations to prevent, suppress and punish genocide.
