The Convention on the Prevention and Punishment of the Crime of Genocide (CPPCG), or the Genocide Convention, is an international treaty that criminalizes genocide and obligates state parties to pursue the enforcement of its prohibition. It was the first legal instrument to codify genocide as a crime, and the first human rights treaty unanimously adopted by the United Nations General Assembly, on 9 December 1948, during the third session of the United Nations General Assembly. The Convention entered into force on 12 January 1951 and has 152 state parties as of 2022.
