Context paragraphs:
Vé (shrine): In Germanic paganism, a vé (Old Norse) or wēoh (Old English) is a type of shrine or sacred enclosure.  The term appears in skaldic poetry and in place names in Scandinavia (with the exception of Iceland), often in connection with a Norse pagan deity or a geographic feature.  The name of the Norse god Vé refers to the practice.  Andy Orchard says that a vé may have surrounded a temple or have been simply a marked, open place where worship occurred.  Orchard points out that Tacitus, in his 1st century CE work "Germania", says that the Germanic peoples, unlike the Romans, "did not seek to contain their deities within temple walls."

Old Norse religion: Old Norse religion developed from early Germanic religion during the Proto-Norse period, when the North Germanic peoples separated into a distinct branch of the Germanic peoples.  It was displaced by Christianization of the North Germanic peoples.  Scholars reconstruct aspects of North Germanic religion by historical linguistics, archaeology, toponymy, and records left by North Germanic peoples, such as runic inscriptions in the Younger Futhark, a distinctly North Germanic extension of the runic alphabet.  Numerous Old Norse works dated to the 13th century record Norse mythology, a component of North Germanic religion.

List of Germanic deities: In Germanic paganism, the indigenous religion of the ancient Germanic peoples that inhabited Germanic Europe, there were a number of different gods and goddesses.  Germanic deities are attested from numerous sources, including works of literature, various chronicles, runic inscriptions, personal names, place names, and other sources.  This article contains a comprehensive list of Germanic deities outside the numerous Germanic Matres and Matronae inscriptions from the 1st to 5th century CE.

Christianization of Scandinavia: The Christianization of Scandinavia took place between the 8th and the 12th centuries.  The realms of Scandinavia proper, Denmark, Norway and Sweden, established their own Archdioceses, responsible directly to the Pope, in 1104, 1154 and 1164, respectively.  The conversion to Christianity of the Scandinavian people required more time, since it took additional efforts to establish a network of churches.  The Sami remained unconverted until the 18th century.

Proto-Norse language: Proto-Norse (also called Proto-Scandinavian, Primitive Norse, Proto-Nordic, Ancient Nordic, Ancient Scandinavian, Old Nordic, Old Scandinavian, Proto-North Germanic, North Proto-Germanic or Common Scandinavian) was an Indo-European language spoken in Scandinavia that is thought to have evolved as a northern dialect of Proto-Germanic in the first centuries CE.  It is the earliest stage of a characteristically North Germanic language, and the language attested in the oldest Scandinavian Elder Futhark inscriptions, spoken around from the 2nd to 8th centuries (corresponding to the late Roman Iron Age and the Germanic Iron Age).  It evolved into the dialects of Old Norse at the beginning of the Viking Age in about 800, which later themselves evolved into modern North Germanic languages.

Harii: The Harii (Latinized West Germanic "warriors") were, according to 1st century CE Roman historian Tacitus, a Germanic people.  In his work "Germania", Tacitus describes them as using black shields and painting their bodies ("nigra scuta, tincta corpora"), and attacking at night as a shadowy army, much to the terror of their opponents.  Theories have been proposed connecting the Harii to the einherjar, ghostly warriors in service to the god Odin, attested much later among the North Germanic peoples by way of Norse mythology, and to the tradition of the Wild Hunt, a procession of the dead through the winter night sky sometimes led by Odin.

Germanic mythology: Germanic mythology consists of the body of myths native to the Germanic peoples.  Commonly featuring narratives focused on Germanic deities and a large variety of other entities, Germanic mythology dates from the Proto-Germanic period and reaches beyond the Christianization of the Germanic peoples and into modern Germanic folklore.  Germanic mythology includes Norse mythology, Anglo-Saxon mythology, and Continental Germanic mythology.

Germanic religion (aboriginal): Germanic religion refers to the aboriginal myths and rituals of the Germanic peoples from the Iron Age until Christianization during the Medieval period.  It has been described as being "a system of interlocking and closely interrelated religious worldviews and practices rather than as one indivisible religion" and as such consisted of "individual worshippers, family traditions and regional cults within a broadly consistent framework".

Swedish language: Swedish (   ] ) is a North Germanic language, spoken natively by more than 9 million people predominantly in Sweden (as sole official language) and parts of Finland, where it has equal legal standing with Finnish.  It is largely mutually intelligible with Norwegian and Danish.  Swedish is a descendant of Old Norse, the common language of the Germanic peoples living in Scandinavia during the Viking Era.  It is currently the largest of the North Germanic languages by number of speakers.

Rebirth in North Germanic religion: Surviving texts indicate that there was a belief in rebirth in Norse religion.  Examples include figures from eddic poetry and sagas, potentially by way of a process of naming and/or through the family line.  Scholars have discussed the implications of these attestations and proposed theories regarding belief in reincarnation among the Germanic peoples prior to Christianization and potentially to some extent in folk belief thereafter.
