Óðinn throws his spear at the Vanir host, illustration by Lorenz Frølich (1895)

In Norse mythology, the Æsir–Vanir War[a] was a conflict between two groups of deities that ultimately resulted in the unification of the Æsir and the Vanir into a single pantheon. The war is an important event in Norse mythology, and the implications for the potential historicity surrounding accounts of the war are a matter of scholarly debate and discourse.

Fragmented information about the war appears in surviving sources, including Völuspá, a poem collected in the Poetic Edda in the 13th century from earlier traditional sources; in the book Skáldskaparmál in the Prose Edda, written or compiled in the 13th century by Snorri Sturluson; and in euhemerized form in the Ynglinga saga from Heimskringla, also often considered to have been written by Snorri Sturluson in the 13th century.

In two stanzas of Völuspá, the war is recounted by a völva (who refers to herself here in the third person) while the god Óðinn questions her. The war is told rather vaguely, and the fact that it describes a war between the Æsir and the Vanir is not completely certain.[1] In the first of the two stanzas, the völva says that she remembers the first war in the world, when Gullveig was stabbed with spears and then burnt three times in one of Óðinn's halls, yet that Gullveig was reborn three times:

In the second stanza, the völva says that they called Gullveig Heiðr (meaning "Bright One"[3] or potentially "Gleaming" or "Honor"[4]) whenever she came to houses, that she was a wise völva, and that she cast spells. Heiðr performed seiðr where she could, did so in a trance, and was always the favorite of wicked women:[3]

Heith they named her | who sought their home,
The wide-seeing witch, | in magic wise;
Minds she bewitched | that were moved by her magic,
To evil women | a joy she was.

Henry Adams Bellows translation[2]

In two later stanzas, the völva tells Óðinn that all the powers went to the judgment seats and discussed whether the Æsir should pay a fine or if all of the gods should instead have equal tribute, then the völva provides the last of her account of the events surrounding the war. These stanzas are unclear, particularly the second half of the first stanza, but the battle appears to have been precipitated by the entry of Gullveig/Heiðr among the Æsir.[5] The first stanza relates a difficulty in reaching a truce which led to the all-out war described in the second stanza. However, the reference to "all the gods" could, in Lindow's view, indicate a movement towards a community involving both the Æsir and the Vanir.[5] In his translation of the poem, Bellows inverts the order of the two stanzas, stating that "This stanza and stanza 24 [the first and second stanzas] have been transposed from the order in the manuscripts, for the former describes the battle and the victory of the Wanes [Vanir], after which the gods took council, debating whether to pay tribute to the victors, or to admit them, as was finally done, to equal rights of worship."[6] Ursula Dronke points to extensive wordplay on all the meanings of the gildi and the adjective gildr to signal the core issue of whether the Æsir will surrender their monopoly on human tribute and join with the "all-too-popular" Vanir; as their only alternative, they attack again.[7]

On the host his spear | did Othin hurl,
Then in the world | did war first come;
The wall that girdled | the gods was broken,
And the field by the warlike | Wanes was trodden.

Then sought the gods | their assembly-seats,
The holy ones, | and council held,
Whether the gods | should tribute give,
Or to all alike | should worship belong.[6]

Henry Adams Bellows translation, in his inverted order
Translation:

Then all the powers went to the judgment seats
the very holy gods, and discussed this:
whether the æsir should pay a fine,
or all the gods should have tribute.

That was yet the battle of armies, the first one in the world.
Odin let fly and shot into the army,
The shield wall of the fortress of the æsir was broken,
The battle-wise vanir knew how to tread the field.[5]
