Ásatrú is possibly the most significant sect of Greater Heathenry. The term was constructed in the 1800's for the purpose of describing the beliefs of ancient Northern Europeans, and is Icelandic for "Faith in the Æsir." A constructed Old English equivalent for this term is Ēsatroþ, and the Vanic counterpart is Vanatrú. Ásatrú is sometimes written without the accute accent marks, as "Asatru."
In practice, most Ásatrúar do not simply limit themselves to the Æsir in their worship, although the Æsir are easily the most important aspect.
Ásatrúar tend to be more fundamentalist and "by-the-book" than other sects, being more involved in the studies of the Lore than the rest.
In casual speech, the term "Ásatrú" is often used interchangeably with "Heathenry," without reference to specific sects. This is particularly true outside of the United States.
