The Nordic countries are a geographical and cultural region in Northern Europe and the North Atlantic, where it is most commonly known as Norden. It consists of five countries (Denmark, Finland, Iceland, Norway, and Sweden) as well as their autonomous regions (the Åland Islands, the Faroe Islands, and Greenland). The Nordic countries have much in common in their way of life, history, their use of Scandinavian languages and social structure. Politically, Nordic countries do not form a separate entity, but they co-operate in the Nordic Council. Especially in English, Scandinavia is sometimes used as a synonym for the Nordic countries, but that term more properly refers to the three monarchies of Denmark, Norway, and Sweden. Scandinavian Peninsula on the other hand covers mainland Norway and Sweden as well as the northernmost part of Finland.
