The Kingdom of Vingulmark (Old Norse: Vilgumǫrk) is the ancient name of a historical region, the former kingdom of Norway. It currently comprises the counties of Østfold and Akershus, and therefore includes the current Norwegian capital of Oslo, which had not been founded at that time. Archeologists have found rich funeral testimonial sites on the Glomma, Onsøy, Rolvsøy and Tune rivers where the remains of a funerary drakkar, Tune's ship, were found. These discoveries claim that the area was an important center of power during the Viking Age.
There are indications that at least show that the south of the area was under Danish rule at the end of the 9th century. Ohthere of Hålogaland, a Norwegian Viking adventurer who served in the court of English King Alfred the Great, cited that he sailed south from Skiringssal, staying in the Danish harbor for three days. The story of Ohthere is one of the oldest writings where the words "Norway" and "Denmark" are mentioned for the first time.
Norway of the Viking Age was divided into small independent kingdoms ruled by caudillos who ruled the territories, competed for supremacy at sea and political influence, and sought alliances or control over other royal families, either voluntarily or forced. These circumstances led to turbulent periods and heroic lives as recorded in the Heimskringla saga of Icelandic Scallop Snorri Sturluson in the thirteenth century. Bibliography
