Freawaru is a freoðuwebbe or peace-weaver (an important concept in the poem) who is married to Ingeld, King of the Heaðobards and son of Froda.
This marriage was created as a means of ending a feud between the two kingdoms[1] (due to the murder of Froda by the Danes).
[2] An old warrior urged the Heaðobards to revenge,[3] and Beowulf predicts to Hygelac that Ingeld will turn against his father-in-law Hroðgar.
[4] In a version given in the Danish chronicle Gesta Danorum (see below), the old warrior appears as Starkad, and he succeeded in making Ingeld divorce his bride and in turning him against her family.
The Danish king Frotho (Froda) was killed through treachery by a Saxon named Swerting (Swertingus).
