Halfdan the Black

Halfdan the Black (Old Norse: Halfdanr Svarti; ) was a king of Vestfold. He belonged to the House of Yngling and was the father of Harald Fairhair, the first king of a unified Norway.

In sagas Petty kingdoms ca. 860 AD. The kingdom of Halfdan the Black is shown in red According to Íslendingabók, Heimskringla and Fagrskinna, Halfdan was the son of the Yngling King Gudrød the Hunter. Heimskringla also names his mother, as Åsa, daughter of King Harald of Agder, and his half-brother as Olaf Geirstad-Alf. Heimskringla relates that when Halfdan's father was killed, Åsa took the 1 year-old Halfdan and returned to Agder, where Halfdan was raised. When he was 18 or 19 years old, Halfdan became king of Agder. He quickly began adding to his kingdom, through political negotiation and military conquest. He divided the kingdom of Vestfold with his brother Olaf and, through military action, persuaded King Gandalf of Vingulmark to cede half his kingdom. Based on the formulaic nature of his ties to his predecessors, his strong affiliation with Agder, and the failure of an early saga dedicated to him to name any family connections, some scholars have suggested that the linkage to the earlier Yngling dynasty of Vestfold was a later invention, created to associate a conquering Halfdan and his son Harald Fairhair with the family glorified in the Ynglingatal, whom he had displaced.

Halfdan next is said to have subdued an area called Raumarike. To secure his claim to Raumarike, Halfdan first defeated and killed the previous ruler, Sigtryg Eysteinsson, in battle. He then defeated Sigtryg's brother and successor Eystein, in a series of battles. This established Halfdan's claim not only to Raumarike, but also to half of Hedmark, the core of Sigtryg and Eystein's kingdom. These details are only mentioned in Heimskringla.

Fagrskinna and Heimskringla both agree that Halfdan's first wife was Ragnhild, daughter of King Harald Gulskeg (Goldbeard) of Sogn. Halfdan and Ragnhild had a son named "Harald" after his grandfather, and they sent him to be raised at his grandfather's court. Harald Gulskeg, being elderly, named his grandson as his successor, shortly before his death. Ragnhild died shortly after her father, and the young king Harald fell sick and died the next spring. When Halfdan heard about his son's death, he travelled to Sogn and laid claim to the title of king. No resistance was offered, and Halfdan added Sogn to his realm.

Heimskringla'''s narrative adds that each of the districts of his kingdom wanted to claim his grave, and that it was agreed to divide his body into four pieces so each district could bury a piece of it, resulting in four different sites called Halvdanshaugen (from the Old Norse word haugr meaning mound). According to this version, only his head is buried in Ringerike.
