 HIS: This Day in History: 1944 – Belgium, Netherlands and Luxembourg constitute Benelux.

The Benelux Union (Dutch: Benelux Unie; French: Union Benelux; Luxembourgish: Benelux-Unioun), also known as simply Benelux, is a politico-economic union and formal international intergovernmental cooperation of three neighbouring states in western Europe: Belgium, the Netherlands, and Luxembourg. The name Benelux is a portmanteau formed from joining the first few letters of each country's name – Belgium, Netherlands, Luxembourg – and was first used to name the customs agreement that initiated the union (signed in 1944). It is now used more generally to refer to the geographic, economic, and cultural grouping of the three countries.

Cooperation among the governments of Belgium, the Netherlands, and Luxembourg has been a firmly established practice since the introduction of a customs union in 1944 which became operative in 1948 as the Benelux Customs Union. The initial form of economic cooperation expanded steadily over time, leading in 1958 to the signing of the treaty establishing the Benelux Economic Union. Initially, the purpose of cooperation among the three partners was to put an end to customs barriers at their borders and ensure free movement of persons, goods and services among the three countries. It was the first example of international economic integration in Europe since the Second World War. The three countries therefore foreshadowed and provided the model for future European integration, such as the European Coal and Steel Community, the European Economic Community (EEC), and the European Community/European Union (EC/EU). The three partners continue to play this pioneering role. They also launched the Schengen process, which came into operation in 1985, promoting it from the outset. Benelux cooperation has been constantly adapted and now goes much further than mere economic cooperation, extending to new and topical policy areas connected with security, sustainable development, and the economy. Benelux models its cooperation on that of the European Union and is able to take up and pursue original ideas. The Benelux countries also work together in the so-called Pentalateral Energy Forum, a regional cooperation group formed of five members - the Benelux states, France, Germany, Austria, and Switzerland. Formed ten years ago, the ministers for energy from the various countries represent a total of 200 million residents and 40% of the European electricity network. As of November 2019, the Benelux Union has a population of more than 29.55 million.

On 17 June 2008, Belgium (in all its component parts), the Netherlands, and Luxembourg signed a new Benelux treaty in The Hague. The purpose of the Benelux Union is to deepen and expand cooperation among the three countries so that it can continue its role as precursor within the European Union and strengthen and improve cross-border cooperation at every level. Through better cooperation between the countries the Benelux strives to promote the prosperity and welfare of the citizens of Belgium, the Netherlands and Luxembourg.

Benelux works together on the basis of an annual plan embedded in a four-year joint work programme.

Benelux seeks region-to-region cooperation, be it with France and Germany (North Rhine-Westphalia) or beyond with the Baltic States, the Nordic Council, the Visegrad countries, or even further. In 2018 a renewed political declaration was adopted between Benelux and North Rhine-Westphalia to give cooperation a further impetus.

Some examples of recent results of Benelux cooperation: automatic level recognition of all diplomas and degrees within the Benelux, a new Benelux Treaty on Police cooperation, common road inspections and a Benelux pilot with digital consignment notes. The Benelux is also committed to working together on adaptation to climate change. On 5 June 2018 the Benelux (Treaty) celebrated its 60 years of existence. In 2018, a Benelux Youth Parliament was created.

The main institutions of the Union are the Committee of Ministers, the Council of the Union, the General Secretariat, the InterParliamentary Consultative Council and the Benelux Court of Justice while the Benelux Office for Intellectual Property cover the same territory but are not part of the Benelux Union.

The Benelux General Secretariat is located in Brussels. It is the central platform of the Benelux Union cooperation. It handles the secretariat of the Committee of Ministers, the Council of Benelux Union and the various committees and working parties. The General Secretariat provides day-to-day support for the Benelux cooperation on the substantive, procedural, diplomatic and logistical levels. The Secretary-General is Alain de Muyser. The Deputy Secretary-General NL is Frank Weekers and the Deputy Secretary-General BE is Rudolf Huygelen.

The presidency of the Benelux is held in turn by the three countries for a period of one year. The Netherlands hold the presidency in 2020.

In addition to cooperation based on a Treaty, there is also political cooperation in the Benelux context, including summits of the Benelux government leaders. In 2019 a Benelux summit was held in Luxembourg.
