Nibelungs

Nibelungs, or Niflunss, a mythical princely race which furnished the title of the great German epic, the Nibelungenlied. They were vanquished and despoiled of their vast treasures by the hero Siegfried, who wins as his bride Chriemhild, sister of Gunther, King of Burgundy, by overcoming for Gunther the amazon Brunhild of Iceland. Brunhild quarrels with Chriemhild, and persuades Hagen of Tronege to murder Siegfried, Gunther being privy to the crime. Chriemhild then marries Etzel [Attila] of Hungary, invites the Burgundians to Etzel's court, and brings about a war between them and the Huns from which none save Gunther and Hagen escape alive; these are captured by Dietrich of Berne, and put to death by Chriemhild, revenge being completely triumphant.
