Ivar Ragnarsson

"Hyngwar", Ivar's name as it appears in Harley MS 2278, a fifteenth-century Middle English manuscript

Ivar the Boneless (Old Norse: Ívarr hinn Beinlausi [ˈiːˌwɑrː ˈhinː ˈbɛinˌlɔuse]; died c. 873), also known as Ivar Ragnarsson, was a Viking leader who led invasions into England and Ireland. According to the Tale of Ragnarr Loðbrók, he was the son of Aslaug and her husband Ragnar Loðbrok, and was the brother of Björn Ironside, Halvdan (or Hvitserk), Sigurd Snake-in-the-Eye, and Ragnvald. However, it is not known whether this is historically accurate. Ivar is sometimes regarded as the same person as Ímar, a Viking king of Dublin between 870 and 873.
