Denmark and Norway remained under the same monarch until outside forces dissolved the union in 1814.
The union with Norway made it possible for Denmark to inherit the Faroe Islands, Greenland and Iceland.
The tribal Danes came from the east Danish islands (Zealand) and Scania and spoke an early form of North Germanic.
Historians believe that before their arrival, most of Jutland and the nearest islands were settled by tribal Jutes.
From the 8th to the 10th century the wider Scandinavian region was the source of Vikings.
A short note about the Dani in "Getica" by the historian Jordanes is believed to be an early mention of the Danes, one of the ethnic groups from whom modern Danes are descended. The Kingdom of Denmark also comprises two autonomous constituent countries in the North Atlantic Ocean: the Faroe Islands and Greenland.Denmark proper consists of a peninsula, Jutland, and an archipelago of 443 named islands, with the largest being Zealand, Funen and the North Jutlandic Island.During the Pre-Roman Iron Age (500 BC – AD 1), native groups began migrating south, and the first tribal Danes came to the country between the Pre-Roman and the Germanic Iron Age, The Roman provinces maintained trade routes and relations with native tribes in Denmark, and Roman coins have been found in Denmark.Evidence of strong Celtic cultural influence dates from this period in Denmark and much of North-West Europe and is among other things reflected in the finding of the Gundestrup cauldron.
