In
Old Norse, the Æsir (singular Ás, feminine Ásynja, feminine plural Ásynjur,
Anglo-Saxon Ós, from
Proto-Germanic *Ansuz) are the principal gods of the
pantheon of
Norse mythology. They include many of the major figures, such as
Odin,
Frigg,
Thor,
Baldr and
Tyr. A second clan of gods, the
Vanir, is also mentioned in the Norse mythos: the god
Njord and his children,
Freyr and
Freyja, are the most prominent Vanir gods who join the Æsir as hostages after a war between Æsir and Vanir. The Vanir appear to have mainly been connected with cultivation and fertility and the Æsir were connected with power and war.
