The Wulfings, Wylfings or Ylfings[Note 1] (the name means the "wolf clan") was a powerful clan in Beowulf, Widsith and in the Norse sagas. While the poet of Beowulf does not locate the Wulfings geographically, Scandinavian sources define the Ylfings (the Old Norse form of the name) as the ruling clan of the Eastern Geats.[1]
The Wulfings play an important role in Beowulf as Beowulf's father Ecgþeow of the Wægmunding clan had slain one of its members, and was banished for not paying the weregild. The Danish king Hroðgar, who was married to Wealhþeow, a Wulfing woman, graciously paid the weregild, and when Beowulf arrived at the Danish court in order to slay Grendel, Hroðgar interpreted this as a son's gratitude.
In Old Norse sources, the clan figure prominently in the Heimskringla and in Sögubrot, where Hjörvard and his son Hjörmund belong to it. It is also mentioned in the Lay of Hyndla and in Skáldskaparmál where Eiríkr the Wise was one of its members. However, its most famous member was Helgi Hundingsbane who had two poems of his own (Helgakviða Hundingsbana I and Helgakviða Hundingsbana II), in the Poetic Edda, and whose story is also retold in the Völsunga saga.
Helgi Hundingsbane resides at Hringstaðir (probably modern Ringstad, an old royal estate on the same plain).
In the Heimskringla, Högni was the ruler of Östergötland. The legends of Helge Hundingsbane relate that Högni lost his throne to Helgi Hundingsbane. On the other hand, Sögubrot relates that Ivar Vidfamne gave the East Geatish throne to Hjörmund, the son of Hjörvard, after Ingjald's death since it had been the kingdom of Hjörmund's father Hjörvard.
Hann setti konunga ok jarla ok lét ser skatta gjalda; han setti Hjörmund konung, on Hervardar Ylfings, yfir Eystra-Gautland, er átt hafði faðir hans ok Granmarr konungr.
However, this contradicts both the legend of Helge Hundingsbane and the Heimskringla in which the dynasty never lost Östergötland, unless Ivar killed either Högne or Helgi Hundingsbane before giving the throne to their relative Hjörmund.
Known Wulfings
Ylfur or Úlfur (Possible ancestor of the clan), based on clans being named after an ancestor.
Helm Wulfingum ("Helm of the Wulfings"), mentioned in Widsith.
^Word initial w was lost before rounded vowels in Proto-Norse, e.g. wulf corresponds to ulf, and Wulfing/Wylfing corresponds to Ylfing, because the i in the second syllable causes an umlaut in the first syllable u->y.
