Norse Tradition
Æsir
AY-sir (Old Norse Æsir, singular Áss)
The primary tribe of Norse gods, including Odin, Thor, Týr, Frigg, and Baldr — divine rulers associated with sovereignty, war, and wisdom, united with the Vanir after the Æsir-Vanir war.
Æsir (Old Norse, singular Áss, feminine Ásynja) are the primary divine tribe of Norse religion — the gods of sovereignty, war, wisdom, law, and cosmic order. Odin stands as their chief; Thor as their protector; Týr as their embodiment of justice; Frigg as queen; Baldr as the beloved one who dies. Together they hold council at the judgment seat beside Yggdrasil and govern the cosmos until Ragnarök.
The twelve Æsir
Gylfaginning ch. 9 names twelve male Æsir: Óðinn, Þórr, Njörðr (counted among the Æsir after the war), Freyr (likewise), Týr, Bragi, Heimdallr, Höðr, Víðarr, Váli, Ullr, and Forseti. The Ásynjur — the goddesses — receive their own list: Frigg, Freyja, Sif, Skaði, Iðunn, Gerðr, Sigyn, Fulla, Gefjon, Nanna, and others. The distinction matters: the divine family is not exclusively male, and several Ásynjur are among the most theologically significant figures in the corpus.
The Æsir-Vanir war
Völuspá stanzas 21–24 preserve the mythological account of the first war: the Vanir sent Gullveig to the Æsir, who burned her three times and she rose three times. This sparked the Æsir-Vanir war — the battle fought between the two divine tribes, ending in an exchange of hostages that brought Njörðr, Freyr, and Freyja permanently into Ásgarðr. The Ynglinga saga gives a euhemerized version in which the Æsir are a tribe from Asia (a popular false etymology).
The Æsir in practice
Worship of the Æsir forms the core of modern Ásatrú and Heathenry: blót to Odin at the turn of the year, to Thor for protection and frith, to Tyr for justice, to Frigg and the Ásynjur for the wisdom of the home. The Æsir are addressed by name, through their specific attributes, and through the exchange of gifts.
