In Germanic religion , one of the two main groups of deities, the other being the Vanir .
Odin , his wife Frigg , Tyr (the god of war), and Thor were the four Aesir common to the Germanic nations. Balder and Loki were considered Aesir by other peoples. The Aesir were a warlike race and were originally dominant over the Vanir, but after numerous defeats in battle they were forced to grant the Vanir equal status. The poet-god Kvasir was born out of the peace ritual in which the two races mingled their saliva in the same vessel.
