Ásatrú is a modern revival of the ancient Norse pagan religion that worships the Aesir and Vanir, two groups of deities in Norse mythology. Practitioners honor gods such as Odin, Thor, and Freyja, often through rituals, offerings, and community gatherings. The belief system emphasizes a connection to nature, ancestral heritage, and the importance of personal honor. Ásatrú is recognized as a legitimate faith in several countries, and its followers may celebrate traditional festivals like Yule and Midsummer to mark seasonal changes and honor their gods.
