Nordic Council

The Nordic Council is the official body for formal inter-parliamentary Nordic cooperation among the Nordic countries. Formed in 1952, it has 87 representatives from Denmark, Finland, Iceland, Norway, and Sweden as well as from the autonomous areas of the Faroe Islands, Greenland, and Åland. The representatives are members of parliament in their respective countries or areas and are elected by those parliaments. The Council holds ordinary sessions each year in October/November and usually one extra session per year with a specific theme. The council's official languages are Danish, Finnish, Icelandic, Norwegian, and Swedish, though it uses only the mutually intelligible Scandinavian languages—Danish, Norwegian, and Swedish—as its working languages. These three comprise the first language of around 80% of the region's population and are learned as a second or foreign language by the remaining 20%.

In 1971, the Nordic Council of Ministers, an intergovernmental forum, was established to complement the council. The Council and the Council of Ministers are involved in various forms of cooperation with neighbouring areas in Northern Europe, including the German state of Schleswig-Holstein, the Benelux countries and the Baltic states.

During World War II, Denmark and Norway were occupied by Germany; Finland was under assault by the Soviet Union; while Sweden, though neutral, still felt the war's effects. Following the war, the Nordic countries pursued the idea of a Scandinavian defence union to ensure their mutual defence. However, Finland, due to its Paasikivi–Kekkonen policy of neutrality and FCMA treaty with the USSR, could not participate.

It was proposed that the Nordic countries would unify their foreign policy and defence, remain neutral in the event of a conflict and not ally with NATO, which some were planning at the time. The United States, keen on getting access to bases in Scandinavia and believing the Nordic countries incapable of defending themselves, stated it would not ensure military support for Scandinavia if they did not join NATO. As Denmark and Norway sought US aid for their post-war reconstruction, the project collapsed, with Denmark, Norway and Iceland joining NATO as founding members. Finland and Sweden joined NATO in 2023 and 2024, respectively, following the 2022 Russian invasion of Ukraine.

Further Nordic co-operation, such as an economic customs union, also failed. This led Danish Prime Minister Hans Hedtoft to propose, on 13 August 1951, a consultative interparliamentary body. This proposal was agreed by Denmark, Iceland, Norway, and Sweden during a meeting in Copenhagen on 15–16 March 1952. The council's first session was held in the Danish Parliament on 13 February 1953 and it elected Hans Hedtoft as its president. When Finnish-Soviet relations thawed following the death of Joseph Stalin, Finland joined the council in 1955, following a voting in the Parliament of Finland on 28 October that year, effective from 23 December the same year.

On 2 July 1954, the Nordic labour market was created and in 1958, building upon a 1952 passport-free travel area, the Nordic Passport Union was created. These two measures helped ensure Nordic citizens' free movement around the area. A Nordic Convention on Social Security was implemented in 1955. There were also plans for a single market but they were abandoned in 1959 shortly before Denmark, Norway, and Sweden joined the European Free Trade Area (EFTA). Finland became an associated member of EFTA in 1961 and Denmark and Norway applied to join the European Economic Community (EEC).

This move towards the EEC led to desire for a formal Nordic treaty. The Helsinki Treaty outlined the workings of the council and came into force on 24 March 1962. Further advancements on Nordic cooperation were made in the following years: a Nordic School of Public Health, a Nordic Cultural Fund, and Nordic House in Reykjavík were created. Danish Prime Minister Hilmar Baunsgaard proposed full economic cooperation ("Nordek") in 1968. Nordek was agreed in 1970, but Finland then backtracked, stating that its ties with the Soviet Union meant it could not form close economic ties with potential members of the EEC (Denmark and Norway). Nordek was then abandoned.

As a consequence, Denmark and Norway applied to join the EEC and the Nordic Council of Ministers was set up in 1971 to ensure continued Nordic cooperation. In 1970 representatives of the Faroe Islands and Åland were allowed to take part in the Nordic Council as part of the Danish and Finnish delegations. Norway turned down EEC membership in 1972 while Denmark acted as a bridge builder between the EEC and the Nordics. Also in 1973, although it did not opt for full membership of the EEC, Finland negotiated a free trade treaty with the EEC that in practice removed customs duties from 1977 on, although there were transition periods up to 1985 for some products. Sweden did not apply due to its non-alliance policy, which was aimed at preserving neutrality. Greenland subsequently left the EEC and has since sought a more active role in circumpolar affairs.
