Hrólfr Kraki in the context of "Froda"

Hrothgar (Old English: Hrōðgār [ˈr̥oːðɡɑːr]; Old Norse: Hróarr) was a semi-legendary Danish king living around the early sixth century AD.

Hrothgar appears in the Anglo-Saxon epics Beowulf and Widsith, in Norse sagas and poems, and in medieval Danish chronicles. In both Anglo-Saxon and Scandinavian tradition, Hrothgar is a Scylding, the son of Halfdan, the brother of Halga, and the uncle of Hrólfr Kraki. Moreover, in both traditions, the mentioned characters were the contemporaries of the Swedish king Eadgils; and both traditions also mention a feud with men named Fróði and Ingeld. The consensus view is that Anglo-Saxon and Scandinavian traditions describe the same person.

Eadgils, Adils, Aðils, Adillus, Aðísl at Uppsölum, Athisl, Athislus or Adhel was a semi-legendary king of Sweden, who is estimated to have lived during the 6th century.

Beowulf and Old Norse sources present him as the son of Ohthere and as belonging to the ruling Yngling (Scylfing) dynasty. These sources also deal with his war against Onela, which he won with foreign assistance: in Beowulf he gained the throne of Sweden by defeating his uncle Onela with Geatish help, and in two Scandinavian sources (Skáldskaparmál and Skjöldunga saga), he is also helped to defeat Onela in the Battle on the Ice of Lake Vänern, but with Danish help. However, Scandinavian sources mostly deal with his interaction with the legendary Danish king Hrólfr Kraki (Hroðulf), and Eadgils is mostly presented in a negative light as a rich and greedy king. Snorri Sturluson, who documented many of the Scandinavian traditions, reported that the Swedes called him a "great king".

Hrólfs saga kraka, the Saga of King Rolf Kraki, is a late legendary saga on the adventures Hrólfr Kraki, a semi-legendary king in what is now Denmark, and his clan, the Skjöldungs. The events can be dated to the late 5th century and the 6th century. A precursor text may have dated to the 13th century, but the saga in the form that survived to this day dates to c. 1400. Forty-four manuscripts survive, but the oldest one of them is from the 17th century, although a manuscript is known to have existed c. 1461 at the monastery of Möðruvellir in Iceland.

The saga elaborates on the same matter as several other sagas and chronicles in Scandinavian tradition, and also in the Anglo-Saxon poems Beowulf and Widsith. In Beowulf and Widsith, many of the same characters appear in their corresponding Old English forms: Hrólfr Kraki appears as Hroðulf, his father Helgi as Halga, his uncle Hróarr as Hroðgar, his grandfather Halfdan as Healfdene and their clan, the Skjöldungs, as the Scyldings. Moreover, some of their enemies also appear: Fróðo as Froda and king Aðils of Sweden as the Swedish king Eadgils. There are similarities between Bödvar Bjarki killing the beast at the king's court and the killing of Grendel in Beowulf.
