Somewhere around 872 AD, in a fjord on the southwest coast of Norway, a naval battle took place that changed the course of Scandinavian history. It is called the Battle of Hafrsfjord, and while the exact date is still argued over by historians, what happened is broadly accepted: a king called Harald Harfagri — Harald Fairhair — defeated a coalition of petty kings and local chieftains who had come together to stop him before he could stop them.
They failed. And what Harald did with that victory shaped the next hundred years of the Norse world, including the story of a son who would become one of its most notorious figures.
You cannot understand Erik Bloodaxe without understanding Harald. The throne Erik fought to keep, the brothers he killed to hold it, the exile he was eventually driven into — all of it begins here, with a king who was too successful.
The Vow and the Hair
The sagas, as they often do, give the story a romantic origin. Harald, as a young man, was apparently pursuing a woman named Gyda — a chieftain's daughter of opinions. She refused to marry him, the story goes, unless he first became king of all Norway. The implication was that this was an impossible demand, a polite refusal dressed as a challenge.
Harald took it as a challenge. He vowed not to cut or comb his hair until he had unified Norway under a single ruler. For ten years he campaigned, consolidated, fought, negotiated, and married strategically across the Norwegian territories. When it was done — when Hafrsfjord secured his supremacy — he finally washed and combed his hair. It was, by all accounts, magnificent. He became Harald Fairhair.
The story has the texture of legend rather than biography, and historians treat it accordingly. But legends encode something true even when they embroider fact, and the truth encoded here is that Harald's unification of Norway was not quick, not easy, and not bloodless. It took a decade of sustained effort, and it left deep marks on the people it touched.
What Unification Actually Meant
Norway in the 9th century was not a country in the modern sense. It was a collection of territories — some fertile coastal areas, some mountainous inland regions — each governed by its own petty king or powerful jarl. These were men with genuine local authority, loyal followings, and no particular interest in being absorbed into someone else's kingdom.
Harald's consolidation changed their situation fundamentally. Where they had previously held land as their own, with their own legal rights and tax revenues, they now held it under Harald's authority — paying tribute, providing military service, acknowledging his supremacy. Some accepted this. Others did not.
Those who did not had two choices: fight Harald and lose, or leave.
Many left. The sagas are explicit about this. The settlement of Iceland — which began in earnest in the 870s, exactly concurrent with Harald's campaign — was driven in significant part by people who were unwilling to submit to Harald's new order. The Landnámabók, the Book of Settlements, records hundreds of early Icelandic settlers, and a notable proportion of them are described as men who left Norway specifically because of Harald. They took their families, their livestock, their household gods, and their independence, and they sailed west to an empty island in the North Atlantic rather than bend the knee.
This is not a footnote. The settlement of Iceland by people fleeing Harald's Norway is one of the most consequential migrations in Norse history. Iceland became the place where the sagas were written. It became the place where the old traditions were preserved longest. The literary culture that gave us the Eddic poems, the skaldic tradition, the historical sagas — all of it was produced by the descendants of the people who left rather than accept Harald's authority.
History, as it turns out, was written by the ones who ran away.
The Problem of Too Many Sons
Harald lived a long life by Norse standards — probably into his eighties, dying around 932 AD. He had, over the course of that long life, an implausible number of children. The sagas disagree on the exact count, but the number of sons alone runs to somewhere between ten and twenty, depending on which source you consult and how much you trust its arithmetic.
Many of these sons had different mothers. Harald accumulated wives and concubines throughout his reign in the way that powerful early medieval rulers often did — each new marriage or relationship creating an alliance, building loyalty, connecting Harald's household to another region's power. It was rational politics. It was also, as the sons grew up, a dynastic catastrophe waiting to happen.
By the time Harald was old, he had tried to manage the problem by dividing authority among his sons — making various ones sub-kings of different regions while maintaining overall supremacy himself. He had also, by most accounts, elevated Erik above the others. Erik was his chosen successor, the son he wanted to inherit the whole.
The problem with choosing a favourite among twenty sons is that you have just made enemies of the other nineteen.
What Harald Got Right — and What He Got Wrong
The thing that makes Harald's story complicated is that, by most of the measures he cared about, he succeeded. He built a kingdom that did not exist before him. He held it together for his entire reign. He died in his bed, at an advanced age, which was genuinely remarkable for a Norse king who had spent decades in active military and political conflict.
What he could not do was transmit the stability he had built. A king can unify a territory in his own lifetime through the force of his personality, his military reputation, and the relationships he has personally cultivated. None of those things transfer smoothly to a successor — particularly not to a succession dispute among a large number of armed, ambitious, mutually hostile sons.
Erik inherited the throne and promptly began killing brothers — not from pure savagery, though the sagas paint him as violent by nature, but because brothers with royal blood and armed followings were a direct threat to his position. The logic was cold and clear. Several of them died. The ones who survived formed the opposition that would eventually drive Erik out.
The brother who mattered most was Haakon — raised at the court of King Athelstan of Wessex in England, educated, politically sophisticated, and eventually invited back to Norway by the jarls who had grown tired of Erik and his wife Gunnhild. Haakon the Good, as history would call him, deposed Erik around 934 AD without a major battle. The support simply wasn't there for Erik to hold on.
Harald's great mistake, in the end, was not the unification. It was the children.
Harald's Legacy — and Why It Matters for Bloodaxe
Harald Fairhair is remembered in Norwegian national consciousness as a foundational figure — the first King of Norway, the man who made the country. There is a monument to him at Hafrsfjord, three massive Viking swords driven into rock by the fjord's edge, each representing a different region involved in the battle. It is one of the most striking public monuments in Norway.
The historical Harald is harder to locate than the legendary one. Modern historians emphasise that his "unification" was probably more partial and more contested than the sagas suggest — a regional supremacy in the west and south, with considerable independent power persisting elsewhere. The full consolidation of Norway as a political unit would take several more generations and several more rulers.
But the saga Harald — the young man who made an impossible vow, who spent a decade making it possible, who built something genuinely new in the world and then watched his sons fight over the pieces — that figure is real in the ways that matter to literature and memory. He is the shadow behind every scene of Amazon's Bloodaxe, the man whose choices created the world Erik and Gunnhild had to navigate.
Without Harald, there is no Norwegian throne to inherit. Without that throne, there is no fratricidal conflict. Without that conflict, there is no exile. Without the exile, there is no Jorvik, no second kingdom built on English soil, no Battle of Stainmore, no death on the moorland.
The whole story begins with a man who wanted to comb his hair.

FAQ
Was Harald Fairhair a real person?
Yes, though the details of his life are filtered through sagas written down two or three centuries after his death. The broad outlines — a king who consolidated power over much of Norway in the late 9th century, whose sons fought each other after his death — are accepted by historians. The romantic details (the vow, Gyda, the hair) are saga tradition and should be treated as such.
When did Harald Fairhair rule?
He is generally dated to roughly 850–932 AD, with his reign beginning after Hafrsfjord (around 872) and his death in old age around 932. The dates are approximate — the Norse did not keep records in the way that later medieval states did, and the sagas were written long after the events they describe.
How many sons did Harald Fairhair have?
The sagas give different numbers, ranging from around ten to more than twenty. The discrepancy reflects both the genuine complexity of Harald's household and the tendency of saga authors to rationalize and occasionally inflate royal genealogies. What is consistent across sources is that Harald had many sons by multiple mothers, which created the succession crisis that consumed his dynasty after his death.
Why did people leave Norway during Harald's reign?
Harald's unification changed the legal and political status of previously independent chieftains and petty kings. Where they had held land and authority in their own right, they were now expected to hold it under Harald's supremacy — paying tribute and providing military service. Those who found this unacceptable left, principally for Iceland, which was being settled in exactly this period. The connection between Harald's consolidation and the Icelandic settlement is explicitly noted in multiple sources.
What is Harald Fairhair's connection to the Bloodaxe TV series?
Harald is Erik Bloodaxe's father. The entire premise of the Bloodaxe series — Erik's rise, his reign over Norway, his conflict with his brothers and his eventual exile — begins with Harald's choice to unify Norway and designate Erik as his heir. Harald himself may appear in the series covering the earlier period of Erik's life, though the main story centres on the period after Harald's death.
