It was first taken up in 1946, after President Truman called for the reaffirmation of “the principles of the Niirnberg Charter in the context of a general codification of offenses against the peace and security of mankind.” The General Assembly responded promptly by passing three resolutions in rapid succession on December 11, 1946, which created a Committee for the Progressive Development of International Law and its Codification, affirmed the Nuremberg principles, and declared that genocide was an international crime. The International Law Commission (ILC) was charged with preparing the desired Code of Offences after its establishment in 1947.
