Asatru
The basic history, beliefs and practices of the Norse Pagan faith.
History:
Asatru (Icelandic word meaning "Those of the Aseir", or "True to the Aesir."  The Aesir are  the Norse Gods) is a religion based on the  religious traditions of the Nordic and Germanic peoples of Europe.  These  traditions, although officially replaced by Christianity, were kept alive in places such as Iceland and Lapland well into the 19th century.
Deities:
Asatru worship the gods and goddesses of the Nordic peoples, called the Aesir and the Vanir.  These include Thor, god of thunder; Odin, the wise wanderer; Nerthus, the Earth Mother; and Freya, goddess of fertility, magic, and war.  They also revere the spirits of nature (landvaettir) and various guardian spirits, such as the Disir and Alfar (Ancestors).
Beliefs:
Asatru worship the deities of the ancient Scandinavian and Germanic peoples.  They believe in Nine Noble Virtues: courage, truth, honor, loyalty, hospitality, industriousness, perseverance, self-discipline, and self-reliance.  "From these, individuals can decide the appropriate course of action for a given situation and honor themselves, their families, their communities, and their Gods by striving to do what is right."

Asatru do not believe that perfection is a necessity to human existence.  They revere the ancestors and the honored dead, nature, the spirits of the world, and hold hospitality and truth to be important above all.

Asatru hold  major holy celebrations, in Autumn (dísablót), at the beginning of Winter (vetrarblót), Midwinter (jólablót), and the beginning of Spring (sigrblót).  Modern neo-pagans have incorporated these Feasts into the eight festivals of their Wheel of the Year.
Practices:
The faith of Asatru recognizes three types of ritual: Blot, the Sumbel, and the Profession.

Blot, meaning sacrifice, entails a ceremonial offering of mead, beer, or cider to the Gods.  The liquid is consecrated to the God or Goddess being honored, and the worshippers commune with that Deity by drinking a portion of it. The rest is poured as a libation.

The Sumbel is a celebration consisting of  ritualized toasting. The first of the usual three rounds is to the Gods, starting with Odin, who won the mead of poetry from the Giant Suttung. The second round is held to remember the ancestors and other 'honorable dead'. The third round is open.

When a person Professes Asatru, they promise before the Aesir and their Hearth to honor only the Norse Gods.  Their Oath is sworn on a sacred ring and makes them part of the family of the Kindred.
Scripture:
Asatru do not recognize a holy book or set of writings, but most groups do recommend the Eddas, Havamal, and Voluspa as texts with valuable insight into their religion.  The Eddas were written in Medieval Iceland in order to preserve the cultural history and mythology of the Icelandic peoples.
 
Ragnarok:
The Norse believe in Ragnarok, the end of this world.  It is the time when the world will end in a great battle between the Gods and the giants.  Following Ragnarok, a new age of righteousness and peace will commence.
