  • The Iron Age began around 500 to 400 BCE in present-day Denmark and northern Germany, marking the emergence of Germanic languages. Archaeological evidence from this period reveals a cultural patchwork that evolved under wide-ranging influences from earlier Scandinavian religions. Some Bronze Age motifs, such as the wheel cross, reappear in later Iron Age contexts even though solar-oriented belief systems likely died out around 500 BCE. Tacitus wrote accounts of these Germanic peoples around 100 CE, describing priests, open-air sacred sites, and seasonal sacrifices. These observations help explain later Old Norse religion, which developed during the Proto-Norse period when North Germanic peoples separated into distinct branches. The earliest known usage of the term heiðinn appears in the poem Hákonarmál, indicating that Christianity generated consciousness of Old Norse religion as a distinct entity. During the Viking Age, Norse people left Scandinavia and settled throughout Northwestern Europe, bringing their belief system with them. Norwegian settlers colonized Iceland in the 870s, carrying their religious practices to an island where Thor was the most popular god. Place-name evidence suggests that Thor remained the dominant deity on the island, while no place-names connected to Odin exist there. Unlike other Nordic societies, Iceland lacked a monarchy and centralizing authority, allowing both Old Norse and Christian communities to coexist from the time of first settlement.

  • Old Norse religion was polytheistic, featuring many anthropomorphic gods and goddesses who expressed human emotions and sometimes had children. One god, Baldr, is said in myths to have died, while Loki remains imprisoned beneath the earth until Ragnarok when he will fight against the gods. Major deities among the Aesir include Thor, often referred to as Asa-Thor, Odin, and Tyr. Very few Vanir are named in sources: Njordr, his son Freyr, and his daughter Freyja. Some mythographers suggest the war between Aesir and Vanir reflects recollection of conflict between adherents of different belief systems in Scandinavia. The universe began as a void known as Ginnungagap before Ymir appeared, followed by gods who lifted the earth out of the sea. Völuspá portrays Yggdrasil as a giant ash tree where deities meet daily to pass judgment. Grímnismál claims that a serpent gnaws at its roots while a deer grazes from higher branches, with a squirrel running between them exchanging messages. The term Yggr means terrifier and is a synonym for Oðinn, making Yggdrasil mean Oðinn's Steed. The Ragnarok story suggests an idea of inescapable fate pervaded Norse worldviews, possibly reflecting the period of conflict between paganism and Christianity. Many scholars believe the giants were not worshipped, though this has been questioned. Localized and ancestral deities remained strong presences among Finns and Sámi even after Christianization.

  • The primary religious ritual in Norse religion appears to have been sacrifice, or blót, with many texts referring to these practices. The Saga of Hákon the Good states there were obligatory blóts where animals were slaughtered and their blood sprinkled on altars and temple walls. Adam of Bremen described a festival every nine years at Uppsala where nine males of every kind of animal were sacrificed and bodies hung in the temple grove. Animal sacrifices could take place before duels, after business concluded, before sailing to ensure favorable winds, and at funerals. Ibn Fadlan's account of a ship burial includes the sacrifice of a dog, draft animals, cows, a rooster, and a hen alongside that of a servant girl. Temple wells in which people were sacrificially drowned are mentioned in Adam of Bremen's account and Icelandic sagas as blótkelda or blótgröf. Human victims were included among those hanging in trees at Uppsala according to Adam of Bremen. Archaeological evidence supports Ibn Fadlan's report of funerary human sacrifice, such as at Birka where a decapitated young man was placed atop an older man buried with weapons. At Gerdrup near Roskilde, a woman was buried alongside a man whose neck had been broken. Many details of Ibn Fadlan's account are born out by archaeology, though elements like sexual encounters remain invisible to archaeological evidence.

  • The myth preserved in Hávamál shows Odin hanging for nine nights on Yggdrasil, sacrificing himself to secure knowledge of runes and other wisdom in what resembles an initiatory rite. The gods were associated with two distinct forms of magic: Odin particularly with runes and galdr, while seiðr and spæ involved both magic and divination. Seiðr was practiced mostly by women known as völur and spé-wives, often in communal gatherings at a client's request. Ninth- and 10th-century female graves containing iron staffs and grave goods have been identified as those of seiðr practitioners. According to Ynglinga saga, Freyja taught seiðr to the Aesir, but it involved so much ergi that its use was reserved for priestesses except for Odin himself. Practitioners such as Þorbjörg Lítilvölva in the Saga of Erik the Red appealed to spirit helpers for assistance. Many scholars point to similarities between reported seiðr ceremonies and shamanism, with some regarding it as borrowing from Sami or Balto-Finnic traditions. Jan de Vries regarded seiðr as an indigenous shamanic development among the Norse, though applicability remains disputed. Charms associated with runes were central to treating disease in both humans and livestock throughout Old Norse society. Religious practices often took place outdoors at sites like Hove in Trøndelag where offerings were placed at posts bearing images of gods.

  • The Nordic world first encountered Christianity through settlements in Christian British Isles and trade contacts with eastern Christians in Novgorod and Byzantium. By the time Christianity arrived in Scandinavia, it was already accepted religion across most of Europe. Danish king Harald Klak converted in 826, likely to secure political alliance with Louis the Pious against rivals for throne. The Danish monarchy reverted to Old Norse religion under Horik II who ruled from 854 until around 867. Norwegian king Hákon the Good had converted while in England but kept his faith largely private while encouraging Christian priests to preach among population. Three churches built near Trondheim were burned down by angry pagans according to Heimskringla. Haakon Sigurdsson later became de facto ruler of Norway and although he agreed to be baptized under pressure from Danish king, he enthusiastically supported pagan sacrificial customs. His reign from 975 to 995 saw emergence of state paganism binding together Norwegian identity with pagan identity. Olaf Tryggvason took power after Haakon's death in 995 and enthusiastically promoted Christianity, forcing high-status Norwegians to convert and destroying temples. Sweden was last Scandinavian country to officially convert, though Swedish kings had converted by early 11th century and country was fully Christian by early 12th. Across Germanic Europe, conversion to Christianity was closely connected to social ties with mass conversion being norm rather than individual conversion.

  • Present-day knowledge of Old Norse religion contains vast gaps requiring caution against basing wild assumptions on isolated details. The first extensive Nordic textual source for Old Norse Religion was Poetic Edda, some of which may have been originally composed by heathens. Hávamál contains information on heathen mysticism and ritual obligations according to Ursula Dronke. A large amount of mythological poetry has undoubtedly been lost during oral transmission before being recorded by Christians. Snorri Sturluson's Prose Edda incorporates manual of Norse mythology for use of poets constructing kennings while including numerous citations of lost poems like Þjóðólfr of Hvinir's Haustlöng. Non-Scandinavian sources include Tacitus' Germania from around 100 CE describing religious practices of several Germanic peoples but having little coverage of Scandinavia. Adam of Bremen wrote Gesta Hammaburgensis ecclesiae pontificum between 1066 and 1072 including account of temple at Uppsala. Saxo Grammaticus produced 12th-century Gesta Danorum containing versions of Norse myths and material on pagan religious practices. Muslim Arabs wrote accounts of Norse people they encountered with Ibn Fadlan's 10th-century Risala providing detailed description of ship burial. Archaeological evidence regarding religious practices indicates chronological geographic and class differences far greater than suggested by surviving texts. Place names provide additional source of evidence with theophoric place names indicating importance of deities in different areas dating back before earliest written sources.

  • During romanticist movement of 19th century various northern Europeans took increasing interest in Old Norse religion seeing ancient pre-Christian mythology as alternative to dominant Classical mythology. Artists featured Norse gods and goddesses in paintings and sculptures while their names were applied to streets squares journals and companies throughout parts of northern Europe. Richard Wagner used these narratives as basis for Der Ring des Nibelungen while J.R.R. Tolkien created fictional universe setting novels like The Lord of the Rings inspired by Old Norse tales. During 1930s and 1940s elements of Old Norse and other Germanic religions were adopted by Nazi Germany. Since fall of Nazis various right-wing groups continue using elements of Old Norse and Germanic religion in symbols names and references with some Neo-Nazi groups employing Mjölnir as symbol. Theories about shamanic component of Old Norse religion have been adopted by forms of Nordic neoshamanism with groups practicing what they called seiðr established in Europe and United States by 1990s. Interest in Norse mythology was revived in eighteenth century with scholars turning attention to it in early 19th century influenced by pervasive romanticist sentiment. Academic research into subject began in early 19th century with many operating through nationalism strongly influenced by interpretations by romantic notions about nationhood conquest and religion. Their understanding of cultural interaction also colored by 19th-century European colonialism and imperialism with many regarding pre-Christian religion as singular.
