Person
Halfdan Ragnarsson
Viking chief and King of Jórvík
Halfdan Ragnarsson, or Halfdene to the Anglo-Saxons, is a Viking chief and one of the sons of Ragnar Lodbrok with Aslaug.
It has been suggested that Halfdan is the same person as Ragnar's son Hvitserk.
Halfdan pillages with his brothers Ivar Ragnarsson and Ubbe Ragnarsson, and later becomes a leader of the Great Heathen Army.
The army first lands in England in East Anglia during 865.
