Viking

Chronological History

Vikings[a] is the modern name given to seafaring people primarily[3] from Scandinavia (present-day Denmark, Norway and Sweden),[4][5][6] who from the late 8th to the late 11th centuries raided, pirated, traded and settled throughout parts of Europe.[7][8][9] They also voyaged as far as the Mediterranean, North Africa, the Middle East, and North America. In some of the countries they raided and settled in, this period is popularly known as the Viking Age, and the term "Viking" also commonly includes the inhabitants of the Scandinavian homelands as a collective whole. The Vikings had a profound impact on the early medieval history of Scandinavia, the British Isles, France, Estonia, and Kievan Rus'.[10]

Expert sailors and navigators aboard their characteristic longships, Vikings established Norse settlements and governments in the British Isles, Ireland, the Faroe Islands, Iceland, Greenland, Normandy, the Baltic coast, and along the Dnieper and Volga trade routes across modern-day Russia, Belarus,[11] and Ukraine,[12] where they were also known as Varangians. The Normans, Norse-Gaels, Rus' people, Faroese and Icelanders emerged from these Norse colonies. The Vikings also voyaged to Constantinople, Iran,[13] and Arabia.[14] They were the first Europeans to reach North America, briefly settling in Newfoundland (Vinland). While spreading Norse culture to foreign lands, they simultaneously brought home slaves, concubines and foreign cultural influences to Scandinavia, profoundly influencing the genetic[15] and historical development of both. During the Viking Age the Norse homelands were gradually consolidated from smaller kingdoms into three larger kingdoms: Denmark, Norway and Sweden.

The Vikings spoke Old Norse and made inscriptions in runes. For most of the period they followed the Old Norse religion, but later became Christians. The Vikings had their own laws, art and architecture. Most Vikings were also farmers, fishermen, craftsmen and traders. Popular conceptions of the Vikings often strongly differ from the complex, advanced civilisation of the Norsemen that emerges from archaeology and historical sources. A romanticised picture of Vikings as noble savages began to emerge in the 18th century; this developed and became widely propagated during the 19th-century Viking revival.[16][17] Perceived views of the Vikings as violent, piratical heathens or as intrepid adventurers owe much to conflicting varieties of the modern Viking myth that had taken shape by the early 20th century. Current popular representations of the Vikings are typically based on cultural clichés and stereotypes, complicating modern appreciation of the Viking legacy. These representations are rarely accurate—for example, there is no evidence that they wore horned helmets, a costume element that first appeared in Wagnerian opera.

The etymology of "Viking" is uncertain. In the Middle Ages it came to mean Scandinavian pirate or raider.[19][20][21] The Anglo-Saxons regarded the word wicing as synonymous with pirate and in several Old English sources wicing is translated into the Latin pirata. It was not seen as a reference to nationality, with other terms such as Norðmenn (Northmen) and Dene (Danes) being used for that. In Asser's Life of Alfred the Danes are referred to as pagani (pagans), but this is usually translated as 'Vikings', in modern English, which some regard as a mistake.[22] The earliest reference to wicing in English sources is from the Épinal-Erfurt glossary which dates to around 700, whereas the first known attack by Viking raiders in England at Lindisfarne was in 793.[23][24] The origin of wicing is disputed, with some believing that it is a loan-word from Old Norse.[25]

The form occurs as a personal name on some Swedish runestones. The stone of Tóki víking (Sm 10) was raised in memory of a local man named Tóki who got the name Tóki víking (Toki the Viking), presumably because of his activities as a Viking.[26] The Gårdstånga Stone (DR 330) uses the phrase "Þeʀ drængaʀ waʀu wiða unesiʀ i wikingu" (These valiant men were widely renowned on viking raids),[27] referring to the stone's dedicatees as Vikings. The Västra Strö 1 Runestone has an inscription in memory of a Björn, who was killed when "on a viking raid".[28][29] In Sweden there is a locality known since the Middle Ages as Vikingstad. The Bro Stone (U 617) was raised in memory of Assur who is said to have protected the land from Vikings (Saʀ vaʀ vikinga vorðr með Gæiti).[30][31] There is little indication of any negative connotation in the term before the end of the Viking Age.

Other theories suggest that its origin is from the Old English wicing and Old Frisian wizing that are almost 300 years older, and probably derive from wic itself related to the Latin vicus "village, habitation".[25] Another less popular theory is that víking from the feminine vík, meaning "creek, inlet, small bay".[32]

Various theories have been offered that the word viking may be derived from the name of the historical Norwegian district of Víkin, meaning "a person from Víkin". There are a few major problems with this theory. People from the Viken area were not called "Viking" in Old Norse manuscripts, but are referred to as víkverir, ('Vík dwellers'). In addition, that explanation could explain only the masculine (víkingr) and not the feminine (víking), which is a serious problem because the masculine is easily derived from the feminine but hardly the other way around.[33][34][35]

Another etymology that gained support in the early twenty-first century, derives Viking from the same root as Old Norse vika, f. 'sea mile', originally 'the distance between two shifts of rowers', from the root *weik or *wîk, as in the Proto-Germanic verb *wîkan, 'to recede'.[36][37][38][39] This is found in the Proto-Nordic verb *wikan, 'to turn', similar to Old Icelandic víkja (ýkva, víkva) 'to move, to turn', with well-attested nautical usages.[40] Linguistically, this theory is better attested,[40] and the term most likely predates the use of the sail by the Germanic peoples of North-Western Europe, because the Old Frisian spelling Witsing or Wīsing shows that the word was pronounced with a palatal k and thus in all probability existed in North-Western Germanic before that palatalisation happened, that is, in the 5th century or before (in the western branch).[39][38][41]

In that case, the idea behind it seems to be that the tired rower moves aside for the rested rower on the thwart when he relieves him. The Old Norse feminine víking (as in the phrase fara í víking) may originally have been a sea journey characterised by the shifting of rowers, i.e. a long-distance sea journey, because in the pre-sail era, the shifting of rowers would distinguish long-distance sea journeys. A víkingr (the masculine) would then originally have been a participant on a sea journey characterised by the shifting of rowers. In that case, the word Viking was not originally connected to Scandinavian seafarers but assumed this meaning when the Scandinavians begun to dominate the seas.[36]

In Old English, the word wicing appears first in the Anglo-Saxon poem, Widsith, which probably dates from the 9th century. In Old English, and in the history of the archbishops of Hamburg-Bremen written by Adam of Bremen in about 1070, the term generally referred to Scandinavian pirates or raiders. As in the Old Norse usages, the term is not employed as a name for any people or culture in general. The word does not occur in any preserved Middle English texts. One theory made by the Icelander Örnolfur Kristjansson is that the key to the origins of the word is "wicinga cynn" in Widsith, referring to the people or the race living in Jórvík (York, in the ninth century under control by Norsemen), Jór-Wicings (note, however, that this is not the origin of Jórvík).[42]

The word Viking was introduced into Modern English during the 18th-century Viking revival, at which point it acquired romanticised heroic overtones of "barbarian warrior" or noble savage. During the 20th century, the meaning of the term was expanded to refer to not only seaborne raiders from Scandinavia and other places settled by them (like Iceland and the Faroe Islands), but also any member of the culture that produced said raiders during the period from the late 8th to the mid-11th centuries, or more loosely from about 700 to as late as about 1100. As an adjective, the word is used to refer to ideas, phenomena, or artefacts connected with those people and their cultural life, producing expressions like Viking age, Viking culture, Viking art, Viking religion, Viking ship and so on.[42]

In Eastern Europe, of which parts were ruled by a Norse elite, víkingr came be perceived as a positive concept meaning "hero" in the Russian borrowed form vityaz' (витязь ).[43]

The Vikings were known as Ascomanni ("ashmen") by the Germans for the ash wood of their boats,[44] Dubgail and Finngail ( "dark and fair foreigners") by the Irish,[45] Lochlannaich ("people from the land of lakes") by the Gaels,[46] Dene (Dane) by the Anglo-Saxons[47] and Northmonn by the Frisians.[41]

The scholarly consensus[48] is that the Rus' people originated in what is currently coastal eastern Sweden around the eighth century and that their name has the same origin as Roslagen in Sweden (with the older name being Roden).[49][50][51] According to the prevalent theory, the name Rus' , like the Proto-Finnic name for Sweden (*Ruotsi), is derived from an Old Norse term for "the men who row" (rods-) as rowing was the main method of navigating the rivers of Eastern Europe, and that it could be linked to the Swedish coastal area of Roslagen (Rus-law) or Roden, as it was known in earlier times.[52][53] The name Rus' would then have the same origin as the Finnish and Estonian names for Sweden: Ruotsi and Rootsi.[53][54]

The Slavs and the Byzantines also called them Varangians (Russian: варяги , from Old Norse Væringjar 'sworn men', from vàr- "confidence, vow of fealty", related to Old English wær "agreement, treaty, promise", Old High German wara "faithfulness"[55]). Scandinavian bodyguards of the Byzantine emperors were known as the Varangian Guard. The Rus' initially appeared in Serkland in the 9th century, traveling as merchants along the Volga trade route, selling furs, honey, and slaves, as well as luxury goods such as amber, Frankish swords, and walrus ivory.[26] These goods were mostly exchanged for Arabian silver coins, called dirhams. Hoards of 9th century Baghdad-minted silver coins have been found in Sweden, particularly in Gotland.

During and after the Viking raid on Seville in 844 CE the Muslim chroniclers of al-Andalus referred to the Vikings as Magians (Arabic: al-Majus مجوس), conflating them with Zoroastrians from Persia.[56] When Ahmad ibn Fadlan encountered Vikings on the Volga, he referred to them as Rus.[57][58][59]

The Franks normally called them Northmen or Danes, while for the English they were generally known as Danes or heathen and the Irish knew them as pagans or gentiles.[60]

Anglo-Scandinavian is an academic term referring to the people, and archaeological and historical periods during the 8th to 13th centuries in which there was migration to—and occupation of—the British Isles by Scandinavian peoples generally known in English as Vikings. It is used in distinction from Anglo-Saxon. Similar terms exist for other areas, such as Hiberno-Norse for Ireland and Scotland.

The Viking Age in Scandinavian history is taken to have been the period from the earliest recorded raids by Norsemen in 793 until the Norman conquest of England in 1066.[61] Vikings used the Norwegian Sea and Baltic Sea for sea routes to the south.

The Normans were descendants of those Vikings who had been given feudal overlordship of areas in northern France, namely the Duchy of Normandy, in the 10th century. In that respect, descendants of the Vikings continued to have an influence in northern Europe. Likewise, King Harold Godwinson, the last Anglo-Saxon king of England, had Danish ancestors. Two Vikings even ascended to the throne of England, with Sweyn Forkbeard claiming the English throne in 1013 until 1014 and his son Cnut the Great being king of England between 1016 and 1035.[62][63][64][65][66]

Geographically, the Viking Age covered Scandinavian lands (modern Denmark, Norway and Sweden), as well as territories under North Germanic dominance, mainly the Danelaw, including Scandinavian York, the administrative centre of the remains of the Kingdom of Northumbria,[67] parts of Mercia, and East Anglia.[68] Viking navigators opened the road to new lands to the north, west and east, resulting in the foundation of independent settlements in the Shetland, Orkney, and Faroe Islands; Iceland; Greenland;[69] and L'Anse aux Meadows, a short-lived settlement in Newfoundland, circa 1000.[70] The Greenland settlement was established around 980, during the Medieval Warm Period, and its demise by the mid-15th century may have been partly due to climate change.[71] The Viking Rurik dynasty took control of territories in Slavic and Finnic-dominated areas of Eastern Europe; they annexed Kiev in 882 to serve as the capital of the Kievan Rus'.[72]

As early as 839, when Swedish emissaries are first known to have visited Byzantium, Scandinavians served as mercenaries in the service of the Byzantine Empire.[73] In the late 10th century, a new unit of the imperial bodyguard formed. Traditionally containing large numbers of Scandinavians, it was known as the Varangian Guard. The word Varangian may have originated in Old Norse, but in Slavic and Greek it could refer either to Scandinavians or Franks. In these years, Swedish men left to enlist in the Byzantine Varangian Guard in such numbers that a medieval Swedish law, Västgötalagen, from Västergötland declared no one could inherit while staying in "Greece"—the then Scandinavian term for the Byzantine Empire—to stop the emigration,[74] especially as two other European courts simultaneously also recruited Scandinavians:[75] Kievan Rus' c. 980–1060 and London 1018–1066 (the Þingalið).[75]

There is archaeological evidence that Vikings reached Baghdad, the centre of the Islamic Empire.[76] The Norse regularly plied the Volga with their trade goods: furs, tusks, seal fat for boat sealant, and slaves. Important trading ports during the period include Birka, Hedeby, Kaupang, Jorvik, Staraya Ladoga, Novgorod, and Kiev.

Scandinavian Norsemen explored Europe by its seas and rivers for trade, raids, colonization, and conquest. In this period, voyaging from their homelands in Denmark, Norway and Sweden the Norsemen settled in the present-day Faroe Islands, Iceland, Norse Greenland, Newfoundland, the Netherlands, Germany, Normandy, Italy, Scotland, England, Wales, Ireland, the Isle of Man, Estonia, Ukraine, Russia and Turkey, as well as initiating the consolidation that resulted in the formation of the present day Scandinavian countries.

In the Viking Age, the present day nations of Norway, Sweden and Denmark did not exist, but were largely homogeneous and similar in culture and language, although somewhat distinct geographically. The names of Scandinavian kings are reliably known for only the later part of the Viking Age. After the end of the Viking Age the separate kingdoms gradually acquired distinct identities as nations, which went hand-in-hand with their Christianisation. Thus the end of the Viking Age for the Scandinavians also marks the start of their relatively brief Middle Ages.

Slavic and Viking tribes were "closely linked, fighting one another, intermixing and trading".[77][78][79] In the Middle Ages, ware was transferred from Slavic areas to Scandinavia, and Denmark could be considered "a melting pot of Slavic and Scandinavian elements".[77] It is argued that the presence of Slavs in Scandinavia is "more significant than previously thought"[77] although "the Slavs and their interaction with Scandinavia have not been adequately investigated".[80]

A 10th-century grave of a warrior-woman in Denmark was long thought to belong to a Viking. However, new analyses suggest that the woman may have been a Slav from present-day Poland.[77] The first king of the Swedes, Eric, was married to Gunhild, of the Polish House of Piast.[81] Likewise, his son, Olof, fell in love with Edla, a Slavic woman, and took her as his frilla (concubine).[82] She bore him a son and a daughter: Emund the Old, King of Sweden, and Astrid, Queen of Norway. Cnut the Great, King of Denmark, England and Norway, was the son of a daughter of Mieszko I of Poland,[83] possibly the former Polish queen of Sweden, wife of Eric. Richeza of Poland, Queen of Sweden, married Magnus the Strong, and bore him several children, including Canute V, King of Denmark.[84] Catherine Jagiellon, of the House of Jagiellon, was married to John III, King of Sweden. She was the mother of Sigismund III Vasa, King of Poland, King of Sweden, and Grand Duke of Finland.[85] Ragnvald Ulfsson, son of Jarl Ulf Tostesson and the Wendic Princess Ingeborg, had a Slavic name (Rogvolod, from Slavic Рогволод).[86]

Colonization of Iceland by Norwegian Vikings began in the ninth century. The first source mentioning Iceland and Greenland is a papal letter of 1053. Twenty years later, they appear in the Gesta of Adam of Bremen. It was not until after 1130, when the islands had become Christianized, that accounts of the history of the islands were written from the point of view of the inhabitants in sagas and chronicles.[87] The Vikings explored the northern islands and coasts of the North Atlantic, ventured south to North Africa, east to Kievan Rus (now – Ukraine, Belarus), Constantinople, and the Middle East.[88]

They raided and pillaged, traded, acted as mercenaries and settled colonies over a wide area.[89] Early Vikings probably returned home after their raids. Later in their history, they began to settle in other lands.[90] Vikings under Leif Erikson, heir to Erik the Red, reached North America and set up short-lived settlements in present-day L'Anse aux Meadows, Newfoundland, Canada. This expansion occurred during the Medieval Warm Period.[91]

Viking expansion into continental Europe was limited. Their realm was bordered by powerful tribes to the south. Early on, it was the Saxons who occupied Old Saxony, located in what is now Northern Germany. The Saxons were a fierce and powerful people and were often in conflict with the Vikings. To counter the Saxon aggression and solidify their own presence, the Danes constructed the huge defence fortification of Danevirke in and around Hedeby.[92]

The Vikings witnessed the violent subduing of the Saxons by Charlemagne, in the thirty-year Saxon Wars of 772–804. The Saxon defeat resulted in their forced christening and the absorption of Old Saxony into the Carolingian Empire. Fear of the Franks led the Vikings to further expand Danevirke, and the defence constructions remained in use throughout the Viking Age and even up until 1864.[93]

The south coast of the Baltic Sea was ruled by the Obotrites, a federation of Slavic tribes loyal to the Carolingians and later the Frankish empire. The Vikings—led by King Gudfred—destroyed the Obotrite city of Reric on the southern Baltic coast in 808 AD and transferred the merchants and traders to Hedeby.[94] This secured Viking supremacy in the Baltic Sea, which continued throughout the Viking Age.

Because of the expansion of the Vikings across Europe, a comparison of DNA and archeology undertaken by scientists at the University of Cambridge and University of Copenhagen suggested that the term "Viking" may have evolved to become "a job description, not a matter of heredity," at least in some Viking bands.[95]

The motives driving the Viking expansion are a topic of much debate in Nordic history.

Researchers have suggested that Vikings may have originally started sailing and raiding due to a need to seek out women from foreign lands.[96][97][98][99] The concept was expressed in the 11th century by historian Dudo of Saint-Quentin in his semi imaginary History of The Normans.[100] Rich and powerful Viking men tended to have many wives and concubines; these polygynous relationships may have led to a shortage of eligible women for the average Viking male. Due to this, the average Viking man could have been forced to perform riskier actions to gain wealth and power to be able to find suitable women.[101][102][103] Viking men would often buy or capture women and make them into their wives or concubines.[104][105] Polygynous marriage increases male-male competition in society because it creates a pool of unmarried men who are willing to engage in risky status-elevating and sex seeking behaviors.[106][107] The Annals of Ulster states that in 821 the Vikings plundered an Irish village and "carried off a great number of women into captivity".[108]

One common theory posits that Charlemagne "used force and terror to Christianise all pagans", leading to baptism, conversion or execution, and as a result, Vikings and other pagans resisted and wanted revenge.[109][110][111][112][113] Professor Rudolf Simek states that "it is not a coincidence if the early Viking activity occurred during the reign of Charlemagne".[109][114] The ascendance of Christianity in Scandinavia led to serious conflict, dividing Norway for almost a century. However, this time period did not commence until the 10th century, Norway was never subject to aggression by Charlemagne and the period of strife was due to successive Norwegian kings embracing Christianity after encountering it overseas.[115]

Another explanation is that the Vikings exploited a moment of weakness in the surrounding regions. Contrary to Simek's assertion, Viking raids occurred sporadically long before the reign of Charlemagne; but exploded in frequency and size after his death, when his empire fragmented into multiple much weaker entities.[116] England suffered from internal divisions and was relatively easy prey given the proximity of many towns to the sea or to navigable rivers. Lack of organised naval opposition throughout Western Europe allowed Viking ships to travel freely, raiding or trading as opportunity permitted. The decline in the profitability of old trade routes could also have played a role. Trade between western Europe and the rest of Eurasia suffered a severe blow when the Western Roman Empire fell in the 5th century.[117] The expansion of Islam in the 7th century had also affected trade with western Europe.[118]

Raids in Europe, including raids and settlements from Scandinavia, were not unprecedented and had occurred long before the Vikings arrived. The Jutes invaded the British Isles three centuries earlier, pouring out from Jutland during the Age of Migrations, before the Danes settled there. The Saxons and the Angles did the same, embarking from mainland Europe. The Viking raids were, however, the first to be documented in writing by eyewitnesses, and they were much larger in scale and frequency than in previous times.[116]

Vikings themselves were expanding; although their motives are unclear, historians believe that scarce resources or a lack of mating opportunities were a factor.[119]

The "Highway of Slaves" was a term for a route that the Vikings found to have a direct pathway from Scandinavia to Constantinople and Baghdad while traveling on the Baltic Sea. With the advancements of their ships during the ninth century, the Vikings were able to sail to Kievan Rus and some northern parts of Europe.[120]

Jomsborg was a semi-legendary Viking stronghold at the southern coast of the Baltic Sea (medieval Wendland, modern Pomerania), that existed between the 960s and 1043. Its inhabitants were known as Jomsvikings. Jomsborg's exact location, or its existence, has not yet been established, though it is often maintained that Jomsborg was somewhere on the islands of the Oder estuary.[121]

While the Vikings were active beyond their Scandinavian homelands, Scandinavia was itself experiencing new influences and undergoing a variety of cultural changes.[122]

By the late 11th century, royal dynasties were legitimised by the Catholic Church (which had had little influence in Scandinavia 300 years earlier) which were asserting their power with increasing authority and ambition, with the three kingdoms of Denmark, Norway, and Sweden taking shape. Towns appeared that functioned as secular and ecclesiastical administrative centres and market sites, and monetary economies began to emerge based on English and German models.[123] By this time the influx of Islamic silver from the East had been absent for more than a century, and the flow of English silver had come to an end in the mid-11th century.[124]

Christianity had taken root in Denmark and Norway with the establishment of dioceses in the 11th century, and the new religion was beginning to organise and assert itself more effectively in Sweden. Foreign churchmen and native elites were energetic in furthering the interests of Christianity, which was now no longer operating only on a missionary footing, and old ideologies and lifestyles were transforming. By 1103, the first archbishopric was founded in Scandinavia, at Lund, Scania, then part of Denmark.

The assimilation of the nascent Scandinavian kingdoms into the cultural mainstream of European Christendom altered the aspirations of Scandinavian rulers and of Scandinavians able to travel overseas, and changed their relations with their neighbours.

One of the primary sources of profit for the Vikings had been slave-taking from other European peoples. The medieval Church held that Christians should not own fellow Christians as slaves, so chattel slavery diminished as a practice throughout northern Europe. This took much of the economic incentive out of raiding, though sporadic slaving activity continued into the 11th century. Scandinavian predation in Christian lands around the North and Irish Seas diminished markedly.

The kings of Norway continued to assert power in parts of northern Britain and Ireland, and raids continued into the 12th century, but the military ambitions of Scandinavian rulers were now directed toward new paths. In 1107, Sigurd I of Norway sailed for the eastern Mediterranean with Norwegian crusaders to fight for the newly established Kingdom of Jerusalem; the kings of Denmark and Sweden participated actively in the Baltic Crusades of the 12th and 13th centuries.[125]

A variety of sources illuminate the culture, activities, and beliefs of the Vikings. Although they were generally a non-literate culture that produced no literary legacy, they had an alphabet and described themselves and their world on runestones. Most contemporary literary and written sources on the Vikings come from other cultures that were in contact with them.[126] Since the mid-20th century, archaeological findings have built a more complete and balanced picture of the lives of the Vikings.[127][128] The archaeological record is particularly rich and varied, providing knowledge of their rural and urban settlement, crafts and production, ships and military equipment, trading networks, as well as their pagan and Christian religious artefacts and practices.

The most important primary sources on the Vikings are contemporary texts from Scandinavia and regions where the Vikings were active.[129] Writing in Latin letters was introduced to Scandinavia with Christianity, so there are few native documentary sources from Scandinavia before the late 11th and early 12th centuries.[130] The Scandinavians did write inscriptions in runes, but these are usually very short and formulaic. Most contemporary documentary sources consist of texts written in Christian and Islamic communities outside Scandinavia, often by authors who had been negatively affected by Viking activity.

Later writings on the Vikings and the Viking Age can also be important for understanding them and their culture, although they need to be treated cautiously. After the consolidation of the church and the assimilation of Scandinavia and its colonies into the mainstream of medieval Christian culture in the 11th and 12th centuries, native written sources begin to appear in Latin and Old Norse. In the Viking colony of Iceland, an extraordinary vernacular literature blossomed in the 12th through 14th centuries, and many traditions connected with the Viking Age were written down for the first time in the Icelandic sagas. A literal interpretation of these medieval prose narratives about the Vikings and the Scandinavian past is doubtful, but many specific elements remain worthy of consideration, such as the great quantity of skaldic poetry attributed to court poets of the 10th and 11th centuries, the exposed family trees, the self images, the ethical values, that are contained in these literary writings.

Indirectly, the Vikings have also left a window open onto their language, culture and activities, through many Old Norse place names and words found in their former sphere of influence. Some of these place names and words are still in direct use today, almost unchanged, and shed light on where they settled and what specific places meant to them. Examples include place names like Egilsay (from Eigils ey meaning Eigil's Island), Ormskirk (from Ormr kirkja meaning Orms Church or Church of the Worm), Meols (from merl meaning Sand Dunes), Snaefell (Snow Fell), Ravenscar (Ravens Rock), Vinland (Land of Wine or Land of Winberry), Kaupanger (Market Harbour), Tórshavn (Thor's Harbour), and the religious centre of Odense, meaning a place where Odin was worshipped. Viking influence is also evident in concepts like the present-day parliamentary body of the Tynwald on the Isle of Man.

Common words in everyday English language, such as leg, skin, dirt, sky, egg, kid, anger, window, husband, knife, bag, gift, glove, guest, wing, birth, law, gate, scab, skirt, root, skull, reindeer, happy, wrong, ugly, low, weak, loose, want, give, take, get, smile, guess, seem, hit, kick, scare, crawl, call, lift, both, they, them, and their, stem from the Old Norse of the Vikings and give us an opportunity to understand their interactions with the people and cultures of the British Isles.[131] In the Northern Isles of Shetland and Orkney, Old Norse completely replaced the local languages and over time evolved into the now extinct Norn language. Some modern words and names only emerge and contribute to our understanding after a more intense research of linguistic sources from medieval or later records, such as York (Horse Bay), Swansea (Sveinn's Isle) or some of the place names in Normandy like Tocqueville (Toki's farm).[132]

Linguistic and etymological studies continue to provide a vital source of information on the Viking culture, their social structure and history and how they interacted with the people and cultures they met, traded, attacked or lived with in overseas settlements.[133][134] A lot of Old Norse connections are evident in the modern-day languages of Swedish, Norwegian, Danish, Faroese and Icelandic.[135] Old Norse did not exert any great influence on the Slavic languages in the Viking settlements of Eastern Europe. It has been speculated that the reason for this was the great differences between the two languages, combined with the Rus' Vikings more peaceful businesses in these areas and the fact that they were outnumbered. The Norse named some of the rapids on the Dnieper, but this can hardly be seen from the modern names.[136][137]

The Norse of the Viking Age could read and write and used a non-standardised alphabet, called runor, built upon sound values. While there are few remains of runic writing on paper from the Viking era, thousands of stones with runic inscriptions have been found where Vikings lived. They are usually in memory of the dead, though not necessarily placed at graves. The use of runor survived into the 15th century, used in parallel with the Latin alphabet.

The runestones are unevenly distributed in Scandinavia: Denmark has 250 runestones, Norway has 50 while Iceland has none.[138] Sweden has as many as between 1,700[138] and 2,500[139] depending on definition. The Swedish district of Uppland has the highest concentration with as many as 1,196 inscriptions in stone, whereas Södermanland is second with 391.[140][141]

The majority of runic inscriptions from the Viking period are found in Sweden. Many runestones in Scandinavia record the names of participants in Viking expeditions, such as the Kjula runestone that tells of extensive warfare in Western Europe and the Turinge Runestone, which tells of a war band in Eastern Europe.

Other runestones mention men who died on Viking expeditions. Among them include the England runestones (Swedish: Englandsstenarna) which is a group of about 30 runestones in Sweden which refer to Viking Age voyages to England. They constitute one of the largest groups of runestones that mention voyages to other countries, and they are comparable in number only to the approximately 30 Greece Runestones[142] and the 26 Ingvar Runestones, the latter referring to a Viking expedition to the Middle East.[143] They were engraved in Old Norse with the Younger Futhark.[144]

The Jelling stones date from between 960 and 985. The older, smaller stone was raised by King Gorm the Old, the last pagan king of Denmark, as a memorial honouring Queen Thyre.[145] The larger stone was raised by his son, Harald Bluetooth, to celebrate the conquest of Denmark and Norway and the conversion of the Danes to Christianity. It has three sides: one with an animal image, one with an image of the crucified Jesus Christ, and a third bearing the following inscription:

King Haraldr ordered this monument made in memory of Gormr, his father, and in memory of Thyrvé, his mother; that Haraldr who won for himself all of Denmark and Norway and made the Danes Christian.[146]

Runestones attest to voyages to locations such as Bath,[147] Greece (how the Vikings referred to the Byzantium territories generally),[148] Khwaresm,[149] Jerusalem,[150] Italy (as Langobardland),[151] Serkland (i.e. the Muslim world),[152][153] England[154] (including London[155]), and various places in Eastern Europe. Viking Age inscriptions have also been discovered on the Manx runestones on the Isle of Man.

The last known people to use the Runic alphabet were an isolated group of people known as the Elfdalians, that lived in the locality of Älvdalen in the Swedish province of Dalarna. They spoke the language of Elfdalian, the language unique to Älvdalen. The Elfdalian language differentiates itself from the other Scandinavian languages as it evolved much closer to Old Norse. The people of Älvdalen stopped using runes as late as the 1920s. Usage of runes therefore survived longer in Älvdalen than anywhere else in the world.[156] The last known record of the Elfdalian Runes is from 1929; they are a variant of the Dalecarlian runes, runic inscriptions that were also found in Dalarna.

Traditionally regarded as a Swedish dialect,[157] but by several criteria closer related to West Scandinavian dialects,[158] Elfdalian is a separate language by the standard of mutual intelligibility.[159][160][161] Although there is no mutual intelligibility, due to schools and public administration in Älvdalen being conducted in Swedish, native speakers are bilingual and speak Swedish at a native level. Residents in the area who speak only Swedish as their sole native language, neither speaking nor understanding Elfdalian, are also common. Älvdalen can be said to have had its own alphabet during the 17th and 18th century. Today there are about 2,000-3000 native speakers of Elfdalian.

There are numerous burial sites associated with Vikings throughout Europe and their sphere of influence—in Scandinavia, the British Isles, Ireland, Greenland, Iceland, Faeroe Islands, Germany, Latvia, Estonia, Finland, Russia, etc. The burial practices of the Vikings were quite varied, from dug graves in the ground, to tumuli, sometimes including so-called ship burials.

According to written sources, most of the funerals took place at sea. The funerals involved either burial or cremation, depending on local customs. In the area that is now Sweden, cremations were predominant; in Denmark burial was more common; and in Norway both were common.[162] Viking barrows are one of the primary source of evidence for circumstances in the Viking Age.[163] The items buried with the dead give some indication as to what was considered important to possess in the afterlife.[164] It is unknown what mortuary services were given to dead children by the Vikings.[165] Some of the most important burial sites for understanding the Vikings include:

There have been several archaeological finds of Viking ships of all sizes, providing knowledge of the craftsmanship that went into building them. There were many types of Viking ships, built for various uses; the best-known type is probably the longship.[172] Longships were intended for warfare and exploration, designed for speed and agility, and were equipped with oars to complement the sail, making navigation possible independently of the wind. The longship had a long, narrow hull and shallow draught to facilitate landings and troop deployments in shallow water. Longships were used extensively by the Leidang, the Scandinavian defence fleets. The longship allowed the Norse to go Viking, which might explain why this type of ship has become almost synonymous with the concept of Vikings.[173][174]

The Vikings built many unique types of watercraft, often used for more peaceful tasks. The knarr was a dedicated merchant vessel designed to carry cargo in bulk. It had a broader hull, deeper draught, and a small number of oars (used primarily to manoeuvre in harbours and similar situations). One Viking innovation was the 'beitass', a spar mounted to the sail that allowed their ships to sail effectively against the wind.[175] It was common for seafaring Viking ships to tow or carry a smaller boat to transfer crews and cargo from the ship to shore.

Ships were an integral part of the Viking culture. They facilitated everyday transportation across seas and waterways, exploration of new lands, raids, conquests, and trade with neighbouring cultures. They also held a major religious importance. People with high status were sometimes buried in a ship along with animal sacrifices, weapons, provisions and other items, as evidenced by the buried vessels at Gokstad and Oseberg in Norway[176] and the excavated ship burial at Ladby in Denmark. Ship burials were also practised by Vikings abroad, as evidenced by the excavations of the Salme ships on the Estonian island of Saaremaa.[177]

Well-preserved remains of five Viking ships were excavated from Roskilde Fjord in the late 1960s, representing both the longship and the knarr. The ships were scuttled there in the 11th century to block a navigation channel and thus protect Roskilde, then the Danish capital, from seaborne assault. The remains of these ships are on display at the Viking Ship Museum in Roskilde.

In 2019, archaeologists uncovered two Viking boat graves in Gamla Uppsala. They also discovered that one of the boats still holds the remains of a man, a dog, and a horse, along with other items.[178] This has shed light on death rituals of Viking communities in the region.

Viking society was divided into the three socio-economic classes: Thralls, Karls and Jarls. This is described vividly in the Eddic poem of Rígsþula, which also explains that it was the god Ríg—father of mankind also known as Heimdallr—who created the three classes. Archaeology has confirmed this social structure.[179]

Thralls were the lowest ranking class and were slaves. Slaves comprised as much as a quarter of the population.[180] Slavery was of vital importance to Viking society, for everyday chores and large scale construction and also to trade and the economy. Thralls were servants and workers in the farms and larger households of the Karls and Jarls, and they were used for constructing fortifications, ramps, canals, mounds, roads and similar hard work projects. According to the Rigsthula, Thralls were despised and looked down upon. New thralls were supplied by either the sons and daughters of thralls or captured abroad. The Vikings often deliberately captured many people on their raids in Europe, to enslave them as thralls. The thralls were then brought back home to Scandinavia by boat, used on location or in newer settlements to build needed structures, or sold, often to the Arabs in exchange for silver. Other names for thrall were 'træl' and 'ty'.

Karls were free peasants. They owned farms, land and cattle and engaged in daily chores like ploughing the fields, milking the cattle, building houses and wagons, but used thralls to make ends meet. Other names for Karls were 'bonde' or simply free men. Similar classes were churls and huskarls.

The Jarls were the aristocracy of the Viking society. They were wealthy and owned large estates with huge longhouses, horses and many thralls. The thralls did most of the daily chores, while the Jarls did administration, politics, hunting, sports, visited other Jarls or went abroad on expeditions. When a Jarl died and was buried, his household thralls were sometimes sacrificially killed and buried next to him, as many excavations have revealed.[181]

In daily life, there were many intermediate positions in the overall social structure and it is believed that there must have been some social mobility. These details are unclear, but titles and positions like hauldr, thegn, landmand, show mobility between the Karls and the Jarls.

Other social structures included the communities of félag in both the civil and the military spheres, to which its members (called félagi) were obliged. A félag could be centred around certain trades, a common ownership of a sea vessel or a military obligation under a specific leader. Members of the latter were referred to as drenge, one of the words for warrior. There were also official communities within towns and villages, the overall defence, religion, the legal system and the Things.

Like elsewhere in medieval Europe, most women in Viking society were subordinate to their husbands and fathers and had little political power.[182][183] However, the written sources portray free Viking women as having independence and rights. Viking women generally appear to have had more freedom than women elsewhere,[183] as illustrated in the Icelandic Grágás and the Norwegian Frostating laws and Gulating laws.[184]

Most free Viking women were housewives, and the woman's standing in society was linked to that of her husband.[183] Marriage gave a woman a degree of economic security and social standing encapsulated in the title húsfreyja (lady of the house). Norse laws assert the housewife's authority over the 'indoor household'. She had the important roles of managing the farm's resources, conducting business, as well as child-rearing, although some of this would be shared with her husband.[185]

After the age of 20, an unmarried woman, referred to as maer and mey, reached legal majority and had the right to decide her place of residence and was regarded as her own person before the law.[184] An exception to her independence was the right to choose a husband, as marriages were normally arranged by the family.[186] The groom would pay a bride-price (mundr) to the bride's family, and the bride brought assets into the marriage, as a dowry.[185] A married woman could divorce her husband and remarry.[183][187]

Concubinage was also part of Viking society, whereby a woman could live with a man and have children with him without marrying; such a woman was called a frilla.[187] Usually she would be the mistress of a wealthy and powerful man who also had a wife.[182] The wife had authority over the mistresses if they lived in her household.[183] Through her relationship to a man of higher social standing, a concubine and her family could advance socially; although her position was less secure than that of a wife.[182] There was little distinction made between children born inside or outside marriage: both had the right to inherit property from their parents, and there were no "legitimate" or "illegitimate" children.[187] However, children born in wedlock had more inheritance rights than those born out of wedlock.[185]

A woman had the right to inherit part of her husband's property upon his death,[185] and widows enjoyed the same independent status as unmarried women.[187] The paternal aunt, paternal niece and paternal granddaughter, referred to as odalkvinna, all had the right to inherit property from a deceased man.[184] A woman with no husband, sons or male relatives could inherit not only property but also the position as head of the family when her father or brother died. Such a woman was referred to as Baugrygr, and she exercised all the rights afforded to the head of a family clan, until she married, by which her rights were transferred to her new husband.[184]

Women had religious authority and were active as priestesses (gydja) and oracles (sejdkvinna).[188] They were active within art as poets (skalder)[188] and rune masters, and as merchants and medicine women.[188] There may also have been female entrepreneurs, who worked in textile production.[183] Women may also have been active within military office: the tales about shieldmaidens are unconfirmed, but some archaeological finds such as the Birka female Viking warrior may indicate that at least some women in military authority existed.[189]

These liberties of the Viking women gradually disappeared after the introduction of Christianity,[190] and from the late 13th-century, they are no longer mentioned.[184]

Examinations of Viking Age burials suggests that women lived longer, and nearly all well past the age of 35, as compared to earlier times. Female graves from before the Viking Age in Scandinavia holds a proportional large number of remains from women aged 20 to 35, presumably due to complications of childbirth.[191]

Examinations of skeletal remains also allow us to reconstruct the relative health and nutritional status of boys and girls in the past, using anthropometric techniques. Burials from Scandinavia and other European countries suggests that, in comparison with other societies at the time, female equality was remarkably high in rural Scandinavia. Females in the rural periphery of Nordic countries during the Viking period and the later Middle Ages had relatively high status, resulting in substantial nutritional and health resources being allocated to girls, enabling them to grow stronger and healthier.[192]

Scandinavian Vikings were similar in appearance to modern Scandinavians; "their skin was fair and the hair color varied between blond, dark and reddish". Genetic studies suggest that people were mostly blond in what is now eastern Sweden, while red hair was mostly found in western Scandinavia.[193] Most Viking men had shoulder-length hair and beards, and slaves (thralls) were usually the only men with short hair.[194] The length varied according to personal preference and occupation. Men involved in warfare, for example, may have had slightly shorter hair and beards for practical reasons. Men in some regions bleached their hair a golden saffron color.[194] Females also had long hair, with girls often wearing it loose or braided and married women often wearing it in a bun.[194] The average height is estimated to have been 1.70 m (5 ft 7 in) for men and 1.55 m (5 ft 1 in) for women.[193]

The three classes were easily recognisable by their appearances. Men and women of the Jarls were well groomed with neat hairstyles and expressed their wealth and status by wearing expensive clothes (often silk) and well crafted jewellery like brooches, belt buckles, necklaces and arm rings. Almost all of the jewellery was crafted in specific designs unique to the Norse (see Viking art). Finger rings were seldom used and earrings were not used at all, as they were seen as a Slavic phenomenon. Most Karls expressed similar tastes and hygiene, but in a more relaxed and inexpensive way.[179][195]

Archaeological finds from Scandinavia and Viking settlements in the British Isles support the idea of the well groomed and hygienic Viking. Burial with grave goods was a common practice in the Scandinavian world, through the Viking Age and well past the Christianization of the Norse peoples.[196] Within these burial sites and homesteads, combs, often made from antler, are a common find.[197] The manufacturing of such antler combs was common, as at the Viking settlement at Dublin hundreds of examples of combs from the tenth-century have survived, suggesting that grooming was a common practice.[198] The manufacturing of such combs was also widespread throughout the Viking world, as examples of similar combs have been found at Viking settlements in Ireland,[199] England,[200] and Scotland.[201] The combs share a common visual appearance as well, with the extant examples often decorated with linear, interlacing, and geometric motifs, or other forms of ornamentation depending on the comb's period and type, but stylistically similar to Viking Age art.[202] The practice of grooming was a concern for all levels of Viking age society, as grooming products, combs, have been found in common graves as well as aristocratic ones.[203]

The sagas tell about the diet and cuisine of the Vikings,[204] but first hand evidence, like cesspits, kitchen middens and garbage dumps have proved to be of great value and importance. Undigested remains of plants from cesspits at Coppergate in York have provided much information in this respect. Overall, archaeo-botanical investigations have been undertaken increasingly in recent decades, as a collaboration between archaeologists and palaeoethno-botanists. This new approach sheds light on the agricultural and horticultural practices of the Vikings and their cuisine.[205]

The combined information from various sources suggests a diverse cuisine and ingredients. Meat products of all kinds, such as cured, smoked and whey-preserved meat,[206] sausages, and boiled or fried fresh meat cuts, were prepared and consumed.[207] There were plenty of seafood, bread, porridges, dairy products, vegetables, fruits, berries and nuts. Alcoholic drinks like beer, mead, bjórr (a strong fruit wine) and, for the rich, imported wine, were served.[208][209]

Certain livestock were typical and unique to the Vikings, including the Icelandic horse, Icelandic cattle, a plethora of sheep breeds,[210] the Danish hen and the Danish goose.[211][212] The Vikings in York mostly ate beef, mutton, and pork with small amounts of horse meat. Most of the beef and horse leg bones were found split lengthways, to extract the marrow. The mutton and swine were cut into leg and shoulder joints and chops. The frequent remains of pig skull and foot bones found on house floors indicate that brawn and trotters were also popular. Hens were kept for both their meat and eggs, and the bones of game birds such as black grouse, golden plover, wild ducks, and geese have also been found.[213]

Seafood was important, in some places even more so than meat. Whales and walrus were hunted for food in Norway and the north-western parts of the North Atlantic region, and seals were hunted nearly everywhere. Oysters, mussels and shrimp were eaten in large quantities and cod and salmon were popular fish. In the southern regions, herring was also important.[214][215][216]

Milk and buttermilk were popular, both as cooking ingredients and drinks, but were not always available, even at farms.[217] Milk came from cows, goats and sheep, with priorities varying from location to location,[218] and fermented milk products like skyr or surmjölk were produced as well as butter and cheese.[219]

Food was often salted and enhanced with spices, some of which were imported like black pepper, while others were cultivated in herb gardens or harvested in the wild. Home grown spices included caraway, mustard and horseradish as evidenced from the Oseberg ship burial[208] or dill, coriander, and wild celery, as found in cesspits at Coppergate in York. Thyme, juniper berry, sweet gale, yarrow, rue and peppercress were also used and cultivated in herb gardens.[205][220]

Vikings collected and ate fruits, berries and nuts. Apple (wild crab apples), plums and cherries were part of the diet,[221] as were rose hips and raspberry, wild strawberry, blackberry, elderberry, rowan, hawthorn and various wild berries, specific to the locations.[220] Hazelnuts were an important part of the diet in general and large amounts of walnut shells have been found in cities like Hedeby. The shells were used for dyeing, and it is assumed that the nuts were consumed.[205][217]

The invention and introduction of the mouldboard plough revolutionised agriculture in Scandinavia in the early Viking Age and made it possible to farm even poor soils. In Ribe, grains of rye, barley, oat and wheat dated to the 8th century have been found and examined, and are believed to have been cultivated locally.[222] Grains and flour were used for making porridges, some cooked with milk, some cooked with fruit and sweetened with honey, and also various forms of bread. Remains of bread from primarily Birka in Sweden were made of barley and wheat. It is unclear if the Norse leavened their breads, but their ovens and baking utensils suggest that they did.[223] Flax was a very important crop for the Vikings: it was used for oil extraction, food consumption and most importantly the production of linen. More than 40% of all known textile recoveries from the Viking Age can be traced as linen. This suggests a much higher actual percentage, as linen is poorly preserved compared to wool for example.[224]

The quality of food for common people was not always particularly high. The research at Coppergate shows that the Vikings in York made bread from whole meal flour—probably both wheat and rye—but with the seeds of cornfield weeds included. Corncockle (Agrostemma), would have made the bread dark-coloured, but the seeds are poisonous, and people who ate the bread might have become ill. Seeds of carrots, parsnip, and brassicas were also discovered, but they were poor specimens and tend to come from white carrots and bitter tasting cabbages.[221] The rotary querns often used in the Viking Age left tiny stone fragments (often from basalt rock) in the flour, which when eaten wore down the teeth. The effects of this can be seen on skeletal remains of that period.[223]

Sports were widely practised and encouraged by the Vikings.[225][226] Sports that involved weapons training and developing combat skills were popular. This included spear and stone throwing, building and testing physical strength through wrestling (see glima), fist fighting, and stone lifting. In areas with mountains, mountain climbing was practised as a sport. Agility and balance were built and tested by running and jumping for sport, and there is mention of a sport that involved jumping from oar to oar on the outside of a ship's railing as it was being rowed.[227] Swimming was a popular sport and Snorri Sturluson describes three types: diving, long-distance swimming, and a contest in which two swimmers try to dunk one another. Children often participated in some of the sport disciplines and women have also been mentioned as swimmers, although it is unclear if they took part in competition. King Olaf Tryggvason was hailed as a master of both mountain climbing and oar-jumping, and was said to have excelled in the art of knife juggling as well.

Skiing and ice skating were the primary winter sports of the Vikings, although skiing was also used as everyday means of transport in winter and in the colder regions of the north.

Horse fighting was practised for sport, although the rules are unclear. It appears to have involved two stallions pitted against each other, within smell and sight of fenced-off mares. Whatever the rules were, the fights often resulted in the death of one of the stallions.

Icelandic sources refer to the sport of knattleik. A ball game akin to hockey, knattleik involved a bat and a small hard ball and was usually played on a smooth field of ice. The rules are unclear, but it was popular with both adults and children, even though it often led to injuries. Knattleik appears to have been played only in Iceland, where it attracted many spectators, as did horse fighting.

Hunting, as a sport, was limited to Denmark, where it was not regarded as an important occupation. Birds, deer, hares and foxes were hunted with bow and spear, and later with crossbows. The techniques were stalking, snare and traps and par force hunting with dog packs.

Both archaeological finds and written sources testify to the fact that the Vikings set aside time for social and festive gatherings.[225][226][228]

Board games and dice games were played as a popular pastime at all levels of society. Preserved gaming pieces and boards show game boards made of easily available materials like wood, with game pieces manufactured from stone, wood or bone, while other finds include elaborately carved boards and game pieces of glass, amber, antler or walrus tusk, together with materials of foreign origin, such as ivory. The Vikings played several types of tafl games; hnefatafl, nitavl (nine men's morris) and the less common kvatrutafl. Chess also appeared at the end of the Viking Age. Hnefatafl is a war game, in which the object is to capture the king piece—a large hostile army threatens and the king's men have to protect the king. It was played on a board with squares using black and white pieces, with moves made according to dice rolls. The Ockelbo Runestone shows two men engaged in Hnefatafl, and the sagas suggest that money or valuables could have been involved in some dice games.[225][228]

On festive occasions storytelling, skaldic poetry, music and alcoholic drinks, like beer and mead, contributed to the atmosphere.[228] Music was considered an art form and music proficiency as fitting for a cultivated man. The Vikings are known to have played instruments including harps, fiddles, lyres and lutes.[225]

Experimental archaeology of the Viking Age is a flourishing branch and several places have been dedicated to this technique, such as Jorvik Viking Centre in the United Kingdom, Sagnlandet Lejre and Ribe Viking Center [da] in Denmark, Foteviken Museum in Sweden or Lofotr Viking Museum in Norway. Viking-age reenactors have undertaken experimental activities such as iron smelting and forging using Norse techniques at Norstead in Newfoundland for example.[229]

On 1 July 2007, the reconstructed Viking ship Skuldelev 2, renamed Sea Stallion,[230] began a journey from Roskilde to Dublin. The remains of that ship and four others were discovered during a 1962 excavation in the Roskilde Fjord. Tree-ring analysis has shown the ship was built of oak in the vicinity of Dublin in about 1042. Seventy multi-national crew members sailed the ship back to its home, and Sea Stallion arrived outside Dublin's Custom House on 14 August 2007. The purpose of the voyage was to test and document the seaworthiness, speed, and manoeuvrability of the ship on the rough open sea and in coastal waters with treacherous currents. The crew tested how the long, narrow, flexible hull withstood the tough ocean waves. The expedition also provided valuable new information on Viking longships and society. The ship was built using Viking tools, materials, and much the same methods as the original ship.

Other vessels, often replicas of the Gokstad ship (full- or half-scale) or Skuldelev have been built and tested as well. The Snorri (a Skuldelev I Knarr), was sailed from Greenland to Newfoundland in 1998.[231]

Elements of a Scandinavian identity and practices were maintained in settler societies, but they could be quite distinct as the groups assimilated into the neighboring societies. Assimilation to the Frankish culture in Normandy for example was rapid.[232] Links to a Viking identity remained longer in the remote islands of Iceland and the Faroes.[232]

Knowledge about the arms and armour of the Viking age is based on archaeological finds, pictorial representation, and to some extent on the accounts in the Norse sagas and Norse laws recorded in the 13th century. According to custom, all free Norse men were required to own weapons and were permitted to carry them at all times. These arms indicated a Viking's social status: a wealthy Viking had a complete ensemble of a helmet, shield, mail shirt, and sword. However, swords were rarely used in battle, probably not sturdy enough for combat and most likely only used as symbolic or decorative items.[233][234]

A typical bóndi (freeman) was more likely to fight with a spear and shield, and most also carried a seax as a utility knife and side-arm. Bows were used in the opening stages of land battles and at sea, but they tended to be considered less "honourable" than melee weapons. Vikings were relatively unusual for the time in their use of axes as a main battle weapon. The Húscarls, the elite guard of King Cnut (and later of King Harold II) were armed with two-handed axes that could split shields or metal helmets with ease.

The warfare and violence of the Vikings were often motivated and fuelled by their beliefs in Norse religion, focusing on Thor and Odin, the gods of war and death.[235][236] In combat, it is believed that the Vikings sometimes engaged in a disordered style of frenetic, furious fighting known as berserkergang, leading them to be termed berserkers. Such tactics may have been deployed intentionally by shock troops, and the berserk-state may have been induced through ingestion of materials with psychoactive properties, such as the hallucinogenic mushrooms, Amanita muscaria,[237] or large amounts of alcohol.[238]

The Vikings established and engaged in extensive trading networks throughout the known world and had a profound influence on the economic devel
