The Nibelungenlied (German pronunciation: [ˈniːbəlʊŋən-], [ˈnɪbəlʊŋən-] or [ˌniːbəˈlʊŋənˌliːt] ; Middle High German: Der Nibelunge liet or Der Nibelunge nôt), translated as The Song of the Nibelungs, is an epic poem written around 1200 in Middle High German. Its anonymous poet was likely from the region of Passau. The Nibelungenlied is based on an oral tradition of Germanic heroic legend that has some of its origin in historic events and individuals of the 5th and 6th centuries and that spread throughout almost all of Germanic-speaking Europe. Scandinavian parallels to the German poem are found especially in the heroic lays of the Poetic Edda and in the Völsunga saga.
The poem is split into two parts. In the first part, the prince Siegfried comes to Worms to acquire the hand of the Burgundian princess Kriemhild from her brother King Gunther. Gunther agrees to let Siegfried marry Kriemhild if Siegfried helps Gunther acquire the warrior-queen Brünhild as his wife. Siegfried does this and marries Kriemhild; however, Brünhild and Kriemhild become rivals, leading eventually to Siegfried's murder by the Burgundian vassal Hagen with Gunther's involvement.
