Fredegund in the context of "Chlothar II"

Theuderic II (also spelled Theuderich, Theoderic or Theodoric; in French, Thierry) (c. 587–613), king of Burgundy (595–613) and Austrasia (612–613), was the second son of Childebert II. At his father's death in 595, he received Guntram's kingdom of Burgundy, with its capital at Orléans, while his elder brother, Theudebert II, received their father's kingdom of Austrasia, with its capital at Metz. He also received the lordship of the cities (civitates) of Toulouse, Agen, Nantes, Angers, Saintes, Angoulême, Périgueux, Blois, Chartres, and Le Mans. During his minority, and later, he reigned under the guidance of his grandmother Brunhilda, evicted from Austrasia by his brother Theudebert II.

In 596, Clotaire II, king of Neustria, and Fredegund, Clotaire's mother, took Paris, which was supposed to be held in common. Fredegund, then her son's regent, sent a force to Laffaux and the armies of Theudebert and Theuderic were defeated.

Gudrun (/ˈɡʊdruːn/ GUUD-roon; Old Norse: Guðrún) or Kriemhild (/ˈkriːmhɪlt/ KREEM-hilt; Middle High German: Kriemhilt) is the wife of Sigurd/Siegfried and a major figure in Germanic heroic legend and literature. She is believed to have her origins in Ildico, last wife of Attila the Hun, and two queens of the Merovingian dynasty, Brunhilda of Austrasia and Fredegund.

In both the Continental (German) and Scandinavian traditions, Gudrun/Kriemhild is the sister of the Burgundian king Gunther/Gunnar and marries the hero Siegfried/Sigurd. Both traditions also feature a major rivalry between Gudrun and Brunhild, Gunther's wife, over their respective ranks. In both traditions, once Sigurd has been murdered, Gudrun is married to Etzel/Atli, the legendary analogue of Attila the Hun. In the Norse tradition, Atli desires the hoard of the Nibelungen, which the Burgundians had taken after murdering Sigurd, and invites them to his court; intending to kill them. Gudrun then avenges her brothers by killing Atli and burning down his hall. The Norse tradition then tells of her further life as mother of Svanhild and enemy of Jormunrekr. In the continental tradition, Kriemhild instead desires revenge for her brothers' murder of Siegfried, and invites them to visit Etzel's court intending to kill them. Her revenge destroys both the Huns and the Burgundians, and in the end she herself is killed.
