The Convention on the Prevention and Punishment of the Crime of Genocide was adopted in 1948. It entered into force in January, 1951 by the General Assembly of the United Nations.
It is the legal definition of genocide, the focal point of a long-running campaign by lawyer Rafael Lemkin, who coined the term “genocide” based on the Genocide against Armenians and the Holocaust.
All participating countries were advised to prevent and punish acts of genocide in war-torn and peaceful situations. The number of states that have ratified the Convention is currently 137.
