How has the definition of genocide changed over time

The definition of the crime of genocide as contained in Article II of the Genocide Convention was the result of a negotiating process and reflects the compromise reached among United Nations Member States in 1948 at the time of drafting the Convention. Genocide is defined in the same terms as in the Genocide Convention in the Rome Statute of the International Criminal Court (Article 6), as well as in the statutes of other international and hybrid jurisdictions. Many States have also criminalized genocide in their domestic law; others have yet to do so.
