In this contribution attention is paid to the development of private international law in the Netherlands. The establishment of the Hague Conference on Private International law in 1893 is taken as a starting point. The development of the Conference is roughly sketched. In 1910 the Netherlands Society of International Law was founded, the first national branch of the ILA. An overview is given of the Society's preliminary reports dealing with matters of private international law. The codification of PIL was the subject of the Society's annual meeting in 1990, where the importance of a step-by-step codification was emphasized. The development towards codification is discussed. Codification had already started in 1981 and would come to an end in 2009 with the introduction of the bill on Book 10 of the Dutch Civil Code. It may be expected that the bill will be adopted by Parliament in 2011. Attention is paid to this bill, which introduces the further codification and consolidation of the existing statutes on PIL and recombines them in Book 10 of the Civil Code.
