What is the difference between the "Hague Conference" and the "Hague Conventions"?

The term "Hague Conference on Private International Law" refers to the name of the intergovernmental organisation, whose purpose is "to work for the progressive unification of the rules of private international law" (Article 1 of the Statute of the Hague Conference). The principal method used to achieve this goal consists in the negotiation and drafting of multilateral treaties, which are called Hague Conventions.
