The 1789 opera "Holger Danske", composed by F.L.Æ. Kunzen with a libretto by Jens Baggesen, had a considerable impact on Danish nationalism in the late 18th century. It spawned the literary "Holger feud", which revealed the increasing dissatisfaction among the native Danish population with the German influence on Danish society. Danish intellectual Peter Andreas Heiberg joined the feud by writing a satirical version entitled "Holger Tyske" ("Holger the German") ridiculing Baggesen's lyrics. Ogier is also regarded as the symbol of national identity in Bernhard Severin Ingemann's 1837 epic poem "Holger Danske".
