King Harald Fairhair and the Viking Age

The Gokstad ship was built from timber felled around 890 AD, placing its construction squarely within the reign of one of the most significant figures in Scandinavian history: Harald Fairhair (Old Norse: Haraldr Harfagri), traditionally regarded as the first king to rule over a unified Norway.

From Petty Kingdoms to One Realm

Before Harald’s rise to power, Norway was not a single kingdom but a patchwork of independent petty kingdoms, each ruled by local chieftains or minor kings. Major territories included Vestfold in the southeast, Halogaland in the north, Agder in the south, Hordaland, and Rogaland, among others. These smaller realms were frequently at odds, engaged in raiding and power struggles.

Harald was the son of Halfdan the Black, King of Vestfold, and Ragnhild Sigurdsdotter. Born around the 850s in Leikanger, Sogn, he inherited sovereignty over several small, scattered kingdoms in Vestfold after his father drowned. Beginning around 866 AD, Harald embarked on a military campaign to bring the other kingdoms under his rule, a drawn-out conflict spanning roughly two decades that combined military force with strategic diplomacy and marriage alliances.

The Hair Vow

According to Heimskringla, the saga compilation written by Icelandic historian Snorri Sturluson around 1230, Harald proposed marriage to Gyda Eiriksdottir, daughter of King Eirik of Hordaland. She refused, saying she would not marry him before he was king over all of Norway. In response, Harald swore a vow: he would not cut nor comb his hair until he was sole king of all Norway.

During the approximately ten years of his campaign, he earned the nickname “Tangle-hair” (Old Norse: Haraldr lufa). After achieving his goal, Jarl Ragnvald of More cut and groomed his hair. It was reportedly so fine that he was thereafter called “Fairhair” (harfagri). It is worth noting that the earlier Egil’s Saga uses only the name “Tangle-hair,” suggesting the more flattering epithet may be a later tradition.

The Battle of Hafrsfjord

The decisive moment of Harald’s unification campaign came at the Battle of Hafrsfjord, a naval engagement fought near Stavanger in Rogaland. This battle is traditionally dated to around 872 AD, though most modern researchers place it sometime during the 880s. The traditional 872 date was established by historian Rudolf Keyser in the 19th century and popularized during Norway’s millennial celebration in 1872.

Harald’s forces from Vestfold faced a coalition from the kingdoms of Hordaland, Agder, and Rogaland, led by Kjotve the Rich and Eirik of Hordaland. The battle was fought ship-to-ship in the waters of the fjord, and Harald achieved a decisive victory. According to Snorri Sturluson, after this battle “Harald found himself king over the whole country.”

Naval Power and the Age of the Gokstad Ship

Harald’s military strength rested on superior naval power. Norway’s geography, a fragmented coastline of fjords and islands, made control of the sea the key to political authority. He controlled vital fjords and shipping lanes, allowing him to project influence along the coast and deeper inland. After consolidating power in Norway, Harald used his fleet to assert control over Norse territories in Orkney, Shetland, and the Hebrides, mounting a naval expedition westward to subdue Viking raiders who were using these islands as bases.

The Gokstad ship, built around 890 AD during this period of consolidation, represents the pinnacle of Viking-era shipbuilding. At 23.80 meters long, clinker-built from oak, and capable of speeds over 12 knots, it was the kind of vessel that made Harald’s naval dominance possible. The ship was ultimately used for a high-status burial around 901 AD at Gokstad farm in Sandefjord, Vestfold, the heartland of Harald’s original kingdom.

Emigration: From Norway to Iceland and Beyond

Harald’s rule had a profound and far-reaching consequence: it drove large-scale emigration from Norway. Many chieftains and freemen who refused to submit to his authority or accept his taxation left Norway entirely.

The most significant destination was Iceland. According to the Landnamabok (Book of Settlements) and Islendingabok (Book of Icelanders), Harald’s consolidation of power was a primary cause of the Norse settlement of Iceland. Ingolfur Arnarson became the first permanent Norse settler in Iceland around 874 AD, founding what became Reykjavik. Over the following decades, an estimated 10,000-20,000 people settled the island, mainly from Western Norway, the Scottish Isles, and Ireland.

Others fled to the Faroe Islands. The Faereyinga Saga states that settlers were “spurred by their disapproval of the monarchy of Harald Fairhair” and fled due to the tax burden. Still others settled in Orkney, Shetland, the Hebrides, Scotland, and Ireland.

This chain of emigration had consequences that extended far beyond Harald’s lifetime. The Icelandic settlements eventually produced the explorers who would push further west: Erik the Red to Greenland in 985, and his son Leif Erikson to North America around 1000 AD. In this sense, Harald Fairhair’s unification of Norway set in motion the events that led to the first European contact with the Americas.

A Note on Historical Sources

Much of what we know about Harald Fairhair comes from saga literature written 250-400 years after his lifetime. The primary sources include Snorri Sturluson’s Heimskringla (c. 1230), Fagrskinna (c. 1220), and Islendingabok by Ari Thorgilsson (c. 1122-1133). The only near-contemporary evidence consists of fragmentary skaldic poems attributed to the court poet Thorbjorn Hornklofi, which survive only as quotations in later works.

Modern historians have increasingly questioned the reliability of these accounts. The late 9th-century account of Norway given by the traveler Ohthere to the court of King Alfred the Great of England, and the history written by Adam of Bremen in 1075, record no king of Norway for the relevant period. Some scholars, such as Sverrir Jakobsson, have proposed that Harald Fairhair may be partly a constructed figure, created to explain Iceland’s settlement and to justify Norwegian claims over Iceland in the 13th century.

A common middle-ground position among historians is that Harald was based on a historical king named Harald who ruled western Norway, but that the legend grew considerably beyond the historical figure over the centuries of oral and written transmission. What remains certain is that the period attributed to his reign produced extraordinary achievements in shipbuilding and navigation, as the Gokstad ship itself attests.
