The term "Nordics" encompasses a broader cultural-geographical region than "Scandinavia" proper. Scandinavia strictly includes Denmark, Norway, and Sweden—sharing mutually intelligible languages (North Germanic), intertwined histories, and the Viking Age heritage.
The Nordic region adds Finland, Iceland, and the autonomous territories (Faroe Islands, Greenland, Åland). Finland's Uralic language and distinct history set it apart linguistically, while Iceland's isolation preserved Old Norse roots.
The Nordic Council (1952) and Nordic Council of Ministers coordinate policy across labor markets, education, research, and culture. Passport-free travel predates Schengen. This deep integration makes the Nordics a unique supranational model.
