The riddarasögur (literally 'sagas of knights', also known in English as 'chivalric sagas', 'romance-sagas', 'knights' sagas', 'sagas of chivalry') are Norse prose sagas of the romance genre. Starting in the thirteenth century with Norse translations of French chansons de geste and Latin romances and histories, the genre expanded in Iceland to indigenous creations in a similar style.
While the riddarasögur were widely read in Iceland for many centuries they have traditionally been regarded as popular literature inferior in artistic quality to the Icelanders' sagas and other indigenous genres. Receiving little attention from scholars of Old Norse literature, many remain untranslated.
The production of chivalric sagas in Scandinavia was focused on Norway in the thirteenth century and then Iceland in the fourteenth. Vernacular Danish and Swedish romances came to prominence rather later and were generally in verse; the most famous of these are the Eufemiavisorna, themselves predominantly translations of Norwegian translations of Continental European romances.
