Northern Europe
Northern Europe is the northern part of Europe, commonly including the Nordic countries and often extending to the British Isles and Baltic states.
Nordic countries: A regional group comprising Denmark, Finland, Iceland, Norway, and Sweden, sometimes including associated territories. They form the core of many definitions of Northern Europe.
Baltic Sea: An inland sea in northern Europe, bordered by the Scandinavian Peninsula, Finland, the Baltic states, and central Europe. It connects several countries commonly grouped in the region.
Viking Age: The period, roughly from the late eighth to the eleventh century, when Scandinavian seafarers raided, traded, and settled widely. Scandinavian expansion connected northern Europe to distant parts of the continent.
Central Europe: A region in the middle of Europe whose boundaries vary, commonly including Germany, Poland, and neighboring countries. Its shifting boundary with Northern Europe reflects competing regional schemes.
Nordic Passport Union: An agreement among Nordic countries that removed passport controls for travel between them. It made cross-border movement easier within a major Northern European subregion.
Scandinavia: A region usually comprising Denmark, Norway, and Sweden, with broader definitions sometimes including Finland and Iceland. Its boundaries overlap with, but do not match, Northern Europe.
Scandinavian Peninsula: A peninsula occupied mainly by Norway and Sweden, with a small part of northwestern Finland. Its mountains and coastline shape much of the region's western geography.
Kalmar Union: A dynastic union of Denmark, Norway, and Sweden that lasted from 1397 until Sweden's withdrawal in the early sixteenth century. It briefly united major Nordic kingdoms under one monarch.
Western Europe: The western part of Europe, defined differently across geographic, historical, and political classifications. The British Isles may be classified as Western rather than Northern Europe.
Schengen Area: A group of European countries that have abolished routine internal border checks under shared rules. It provides a wider framework for travel across much of Northern Europe.
