Background

Three bodies shape Denmark's security and its regional role: NATO, the Nordic Council and the Arctic Council.
NATO's founding member countries were Belgium, Canada, Denmark, France, Iceland, Italy, Luxembourg, the Netherlands, Norway, Portugal, the United Kingdom and the United States; the twelve signed the North Atlantic Treaty in Washington, D.C.
The Nordic Council was established in 1952, and Denmark, Iceland, Norway and Sweden were founder members, with Finland joining later.
The Nordic Council has 87 elected members, of whom Denmark, Finland, Norway and Sweden have 20 each; the Faroe Islands and Aland joined in 1970 and Greenland in 1984.
The Arctic Council consists of the eight Arctic States: Canada, the Kingdom of Denmark, Finland, Iceland, Norway, the Russian Federation, Sweden and the United States.
Six Indigenous Peoples' organizations hold Permanent Participant status in the Arctic Council, among them the Inuit Circumpolar Council and the Saami Council.
