"The Erl-King" or "The Alder King" ("Erlkönig" in German) is a [[GermanMedia German ballad]] written by Creator/JohannWolfgangVonGoethe in 1782.

It tells the story of a father who is carrying his sick son, while riding homewards after dark on horseback. The son is convinced that they are being pursued by [[TheFairFolk the Erl-King]], who speaks to him to persuade him to come away with him, while the father insists that the Erl-King doesn't exist -- what he sees, so he tells the boy, are only trees, bushes and fog. Yet the boy will not be calmed, finally screaming that Erl-King is touching him. Even the father is horrified now, and rides the horse as fast as possible. When he arrives, he realizes that the boy is dead.

The poem was inspired by a Danish folk tale, which was translated to German as "Erlkönigs Tochter" ("Daughter of the Arlen King"). However ''Erlkönig'' is a mistranslation (by Johann Gottfried Herder) of the Danish "ellerkonge", which actually means "King of the elves" (that would be "Elfenkönig" in German, in case you wondered). It is possible that Goethe went with the "wrong" translation consciously, as the Erl-King does not fit in with what most people of the era would have recognized as an Elf-King; in the ballad, he seems to serve as a substitute to the GrimReaper or Death. The "rational" interpretation is that the boy is hallucinating from fever.

"Erlkönig" is one the most recognizable of Goethe's works for Germans, thanks to its time-honored status as an inevitable [[SchoolStudyMedia school study medium.]] So is Zhukovsky's adaptation (see below) for Russians.

The poem was set to music (for solo voice and piano) by Music/FranzSchubert in 1815. In Germany in the 20th century the word "Erlkönig" came to denote a car prototype on a nightly Autobahn test drive (speeding, like the father in the ballad, "through night and wind" and fog) in an attempt to evade photojournalists.

!! Some works and artists that reference the "Erl-King":
* Russian XIX-century poet Vassily Zhukovsky translated (or perhaps adapted, it wasn't a very literal translation) Goethe's ballad into a Russian-language poem "Лесной царь" ("The Forest Tsar") with the same plot.
* ''Literature/TheDresdenFiles'' - A powerful member of TheFairFolk goes by this name and the poem is acknowledge to be about him in universe.
* ''Music/SarahBrightman'' - Her song ''Figlio Perduto'' uses an Italian adaptation of this poem for lyrics.
* ''{{Music/Rammstein}}'' - Has a song titled ''Dalai Lama'' which is the Erlkönig [[RecycledInSpace on a plane]].
* ''{{Webcomic/Roommates}}'' - Also has the Erlkönig as character, and a meta webcomic adaptation of the poem, which is his official backstory. He would also [[SchmuckBait love to hear]] about that AlternateCharacterInterpretation mentioned in the main tropes.
* DoomMetal band Pagan Altar's "The Erl King" is an adaptation of the Goethe poem. Also, the Erl King is mentioned in "Armageddon" as being quite pleased with the [[TheEndOfTheWorldAsWeKnowIt nuclear war that destroys humanity.]]
* There is a quite famous SurrealHorror ''{{Film/Labyrinth}}'' DarkFic by [[{{FanficRecs/Labyrinth}} Subtilior]] tiled "Erlkönig". Let's just say the references don't stop at the title.
* ''Le Roi des aulnes'': a 1970 novel written by Michel Tournier
* One episode of ''Series/BoardwalkEmpire'' is titled Erlkönig.
