The Hamðismál is a poem which ends the heroic poetry of the Poetic Edda, and thereby the whole collection. Gudrun had been the wife of the hero Sigurd, whom her brothers had killed. With Sigurd she had had the daughter Svanhild, who had married to the Goth king Ermanaric (Jörmunrekkr). Ermanaric had Svanhild trampled to death by horses, due to which Gudrun wants vengeance, and she agitates her sons (see Jonakr's sons) from a later marriage to kill Ermanaric, cf. Guðrúnarhvöt.
