Germanic heroic legend (germanische Heldensage) is the heroic literary tradition of the Germanic-speaking peoples, most of which originates or is set in the Migration Period (4th-6th centuries AD). Stories from this time period, to which others were added later, were transmitted orally, traveled widely among the Germanic speaking peoples, and were known in many variants. These legends typically reworked historical events or personages in the manner of oral poetry, forming a heroic age. Heroes in these legends often display a heroic ethos emphasizing honor, glory, and loyalty above other concerns. Like Germanic mythology, heroic legend is a genre of Germanic folklore.
Heroic legends are attested in Anglo-Saxon England, medieval Scandinavia, and medieval Germany. Many take the form of Germanic heroic poetry (germanische Heldendichtung): shorter pieces are known as heroic lays, whereas longer pieces are called Germanic heroic epic (germanische Heldenepik). The early Middle Ages preserves only a small number of legends in writing, mostly from England, including the only surviving early medieval heroic epic in the vernacular, Beowulf. Probably the oldest surviving heroic poem is the Old High German Hildebrandslied (c. 800). There also survive numerous pictorial depictions from Viking Age Scandinavia and areas under Norse control in the British Isles. These often attest scenes known from later written versions of legends connected to the hero Sigurd. In the High and Late Middle Ages, heroic texts are written in great numbers in Scandinavia, particularly Iceland, and in southern Germany and Austria. Scandinavian legends are preserved both in the form of Eddic poetry and in prose sagas, particularly in the legendary sagas such as the Völsunga saga. German sources are made up of numerous heroic epics, of which the most famous is the Nibelungenlied (c. 1200).
The majority of the preserved legendary material seems to have originated with the Goths and Burgundians.
