On the eve of International Day of Commemoration and Dignity of the Victims of the Crime of Genocide and of the Prevention of this Crime, 9 December, we looked at the origin of the word. Mr. Lemkin developed the term partly in response to the Nazi policies of systematic murder of Jewish people during the Holocaust, but also in response to previous instances in history of targeted actions aimed at the destruction of particular groups of people.

Later on, he led the campaign to have genocide recognized and codified as an international crime. First recognized as a crime under international law by the UN General Assembly in 1946, genocide was codified as an independent crime in the 1948 Convention on the Prevention and Punishment of the Crime of Genocide.
