The Nibelungenlied is a medieval epic poem from Germany, composed around the early 13th century. It tells the story of the hero Siegfried, who slays a dragon and acquires a treasure known as the Nibelungen hoard. The narrative explores themes of love, betrayal, and revenge, primarily focusing on the tragic fate of its characters. The poem is divided into two main parts: the first details Siegfried's marriage to Kriemhild and his subsequent murder, while the second part follows Kriemhild's quest for vengeance against those responsible for his death. The Nibelungenlied is considered a cornerstone of German literature and has influenced various adaptations in art and culture.
