 Supposedly, two of his sons, Eric Bloodaxe and Haakon the Good, succeeded Harald to become kings after his death.Most of Harald's biography remains uncertain, since the extant accounts of his life in the sagas were set down in writing around three centuries after his lifetime.Indeed, although it is possible to write a detailed account of Harald as a character in medieval Icelandic sagas (as this entry does), it is even possible to argue that there was no such historical figure at all.
