Who can trace their lineage back to a king of Denmark and Norway that died in 985/86?
History of Denmark The history of Denmark as a unified kingdom began in the 8th century, but historic documents describe the geographic area and the people living there—the Danes—as early as 500 AD. These early documents include the writings of Jordanes and Procopius. With the Christianization of the Danes c. 960 AD, it is clear that there existed a kingship in Scandinavia, controlling the current Danish territory roughly speaking. Queen Margrethe II can trace her lineage back to the Viking kings Gorm the Old and Harald Bluetooth from this time, thus making the Monarchy of Denmark the oldest in Europe. The area now known as Denmark has a rich prehistory, having been populated by several prehistoric cultures and people for about 12,000 years, since the end of the last ice age.
House of Bjelbo The House of Bjelbo (Swedish: "Bjälboätten" ), also known as the House of Folkung ("Folkungaätten"), was an Ostrogothian Swedish family that provided several medieval Swedish bishops, jarls and kings. It also provided three kings of Norway, and one king of Denmark in the 14th century.
