Recognised as one of the most prominent kings of the Anglo-Saxon era, King Cnut (Canute) conquered England, Denmark, Norway, and areas of Sweden. Here is everything you need to know about the Danish royal king…
King Cnut: a brief biography
Born: c985–995 AD, Denmark
Died: AD 12 November 1035, Dorset, England
Ruled England: AD 1016–1035
Remembered for: Conquering kingdoms across northern Europe and becoming king of England, Denmark, Norway, and areas of Sweden.
Family: Cnut’s father was the Danish prince Svein ‘Forkbeard’, who became king of England in 1013. Little is known about Cnut’s mother, but it has been suggested that she may have been the daughter of King Mieszko I of Poland.
Cnut married Ælfgifu of Northampton (date unknown), and together they had two children named Svein and Harold. However, it has been suggested that the church did not officially recognise this marriage, for reasons that are unclear, thus Cnut was allowed to marry again.
Cnut married Emma of Normandy in 1017, and they had two children – a son named Harthacnut and a daughter named Gunhilda.
Where was Cnut born?
Cnut descended from some notable Danish rulers
The Danish royal dynasty from which Cnut descended was actually relatively young – it had been established by his great-grandfather, Gorm the Old. Gorm was a confirmed pagan worshipper who respected the old Norse gods such as Thor, Odin and Freya.
Gorm’s son Harald was of a different disposition – he adopted Christianity and firmly established the religion in Denmark for the first time. Harald was known for an unusual distinguishing physical characteristic – his teeth appeared to be blue. This may be because they were just in poor condition and were discoloured as a result. Another possible explanation is that Harald may have filed his teeth and carved grooves in them, which he then coloured with blue dye. At any rate, he became known as Harald Bluetooth. Modern Bluetooth technology (a joint initiative between various Scandinavian companies) was named after Harald for the part that he played in trying to unify Denmark and Norway during his reign.
Harald Bluetooth was the father of Sweyn Forkbeard (who in turn was the father of Cnut). Harald and Sweyn came to blows and there was a bitter civil war between them. Harald was eventually defeated and died soon after fleeing from Denmark.

The exact date and location of Cnut’s birth is unknown, and there is little evidence of his upbringing in the 10th century.

When did Cnut first travel to England?
Cnut’s first experience of invading England ended in personal disaster
Cnut grew up at a time when the crown of England was being ferociously fought over by the Anglo-Saxons and the Vikings. In 1013, he accompanied his father Sweyn Forkbeard on an invasion of England and deposed the king, Æthelred ‘The Unready’. As far as we know, this was the first time Cnut had been to the country. Sweyn was not just raiding England; by this time, he was trying to conquer it. It soon looked like Sweyn was about to become king of the country; he had been so successful in battle that the current king Æthelred had fled. But then, just as it appeared that Sweyn’s triumph was complete, he suddenly died on 3 February 1014.
Cnut, probably then just a teenager, seems to have been caught with his guard down. He assumed that he would merely assume the role left vacant by his father’s death. But he was faced by an unexpected English backlash. An army caught him unawares and a catastrophic defeat followed. Cnut barely escaped. The English nobles then invited Æthelred to return to the throne.
When Cnut left England by ship, he left behind a number of hostages – minus their ears and noses. It was a stark warning to those who did not support him that they could be in for a seriously difficult time in the future.
In 1015, Æthelred’s health deteriorated and England became divided over who should succeed the throne if he were to die. Some parts of the country allied with Cnut and the Vikings, while others showed support for Æthelred’s son, Edmund Ironside.

How did Cnut become king of England?
For a brief period in 1016, England had two kings at the same time
Opportunity arose for Cnut in 1016. Following the death of Anglo-Saxon king Æthelred ‘the Unready’, his son Edmund Ironside became king of England. However, Ironside did not have unanimous support, even from the English. Some seem to have reasoned that Cnut, who had returned to the country with a newly-raised army, was a better bet. Cnut and Edmund fought a vicious and drawn-out war. After several major clashes, the conflict’s final climactic battle was fought at Ashingdon (‘Assandun’) in Essex.
Cnut was triumphant and Ironside was forced to flee for his life. Cnut caught up with him in Gloucestershire in October 1016. However, rather than fight yet another battle, the two men agreed to divide England between them. Edmund was to have the kingdom of Wessex and Cnut the rest of England. Whether or not this unusual arrangement would have ever worked in the long-run we shall never know. Conveniently for Cnut, Ironside died just a few weeks later, on 30 November 1016, most probably after sustaining battle wounds. Cnut was now the undisputed successor to the English throne, and he was crowned at the Old St Paul’s cathedral in January 1017.
In 1018, Cnut’s brother, Harald, the king of Denmark, died, and Cnut succeeded to the Danish throne. In 1027, Cnut traveled to Scotland where the Scottish kings acknowledged Cnut as the legitimate ruler of England, bringing peace to the two rivaling countries.
Did you know?
In order to secure his position as king of England, Cnut married Æthelred’s widow, Emma of Normandy, in 1017. He also had any remaining enemies killed, and he exiled members of Æthelred’s family who were possible threats to his position on the throne.
How did Cnut deal with the issue of Viking raiders during his reign?
He forked out huge sums to get rid of raiders
‘Danegeld’ was the term used for money paid to troublesome Viking raiders, in order to make them go away. The late king Æthelred was infamous for his frequent Danegeld payments, though it was not Æthelred who made the largest Danegeld payment, but Cnut.
The idea of paying off raiders was not new; it had been used in Carolingian Francia two centuries earlier and even the heroic Alfred the Great had used it as a tactic. However, there were problems with the approach. Even if one party of raiders went away, another would soon take their place and the payments would need to be repeated, which was clearly an expensive scenario. Meanwhile, some raiders, such as Sweyn Forkbeard, might go away for a short time before simply coming back again.
When Cnut first became king, he was faced with the problem of what to do with thousands of unemployed Viking raiders. His solution was to pay them to go away. The cost was enormous – Cnut raised 10,000 Troy lbs [a measurement used to measure gold and silver] of silver from London and 72,500 Troy lbs from the rest of England to finance his policy. This was a mammoth sum at the time; while it is difficult to meaningfully convert into modern currency, it amounted to more than 30,000kg of silver. Cnut’s payment was greater than any previous Danegeld sum (the former highest was 48,000 pounds, paid in 1012 during the reign of Æthelred). But although it must have caused great pain to the taxpayers of England, the policy largely seems to have worked, as Viking raids diminished substantially.

How did Cnut become king of Denmark?
Cnut inherited Denmark from his older brother, not his father
At the time of Cnut’s rule, the laws of Viking succession were fairly flexible. When a great leader such as Sweyn Forkbeard died, it was not unusual for his patrimony to be divided between his sons, rather than the eldest taking everything. In theory, this helped prevent disputes involving disgruntled younger sons, though in reality these disagreements were still common.
Because Sweyn Forkbeard died while he and Cnut were in England, another of his sons, Harald, took over control of Denmark. Cnut was forced to fight for the country he was in, otherwise he would have been left with nothing. In 1018, Harald died without an obvious heir, leaving Denmark available for his brother Cnut. He seems to have taken the country without too much difficulty and held on to it for the rest of his reign.
Norway was a different matter. Although Sweyn Forkbeard had conquered the country at the end of the 11th century, it was never fully assimilated into his territories and he lost control of it after an uprising there. In 1030 Cnut won a decisive victory against his opponent, King Olaf II of Norway, at the battle of Stiklestad, but his subsequent reign in the country was short-lived. Those he appointed to be his representatives there were not popular, partly due to a period of extended famine, and they were ejected from the country. Norway was never securely integrated into Cnut’s kingdom.
Who was Cnut’s wife and what do we know about her?
Emma, Cnut’s wife, was the only woman to marry two different kings of England
Emma’s first husband was the luckless Æthelred ‘the Unready’. The royal couple had several children, one of whom would later become King Edward the Confessor. When Æthelred died in 1016, Emma seems to have left the country and returned to Normandy.
When she returned to England in 1017, it was as Cnut’s wife. Emma was a loyal lieutenant for Cnut and their marriage was a great political success. Emma seems to have had a strong instinct for political survival. Cnut and Emma had several children together, including Harthacnut, who later became king of both England and Denmark for a short time.
However, marital alliances at the time could be complicated. When Cnut married Emma, he already had a partner, Ælfgifu of Northampton. Whether they were ever married or not is unclear. It was quite normal at that period for kings and noblemen to have a concubine rather than an official wife and it would appear that Ælfgifu fell into that category. Their relationship did produce several children. One of them, Harold ‘Harefoot’, was king of England for a short time.
Ælfgifu and Emma were bitter rivals for decades, and they both outlived Cnut.

How did Cnut view England and its people?
Despite being Danish, Cnut was an Anglophile
Cnut was an astute statesman. Rather than rejecting the former Anglo-Saxon kings of England, he went out of his way to show support for them. He did this by visiting or making gifts to shrines associated with Anglo-Saxon kings, such as Shaftesbury Abbey, where King Edward the Martyr lay buried, or Wilton Abbey, linked with St Edith, sister of Æthelred. He even paid his respects to his old adversary, Edmund Ironside, at Glastonbury Abbey. This Anglophile policy was a smart political move on Cnut’s part, as it was well regarded by his English subjects.
He also adopted a new law code, which was regarded as introducing a strong but fair regime to England. Cnut based these laws on those of the Anglo-Saxon king Edgar, whose reign was regarded as a golden age.
Cnut also not only adopted English policies, but also introduced them to his overseas territories with a good degree of success. He took full advantage of the English coinage system, which was renowned for its quality at the time. He ensured that this quality was maintained and introduced a vastly improved coinage into Denmark. There are a number of cases recorded where the moneyers working in Denmark were of English origin.

Cnut was praised by his contemporaries for strictly enforcing English law and justice, and he strengthened the crown’s finances by establishing new trade routes between England and Scandinavia. Cnut successfully created a unified England, and it has been suggested that he was the first English ruler to not face any internal rebellions throughout his reign.
How did Cnut use religion to bolster his power?
Cnut made his reputation as a passionate supporter of the church
Cnut was in many senses a Viking, and is probably best known as such today. He led his army using Viking tactics and launched raids on enemy territory using instantly recognisable longships. He was also fond of skalds [Scandinavian bards, or minstrels] who related old Viking sagas and tales.
Yet, it was as a patron of the church that Cnut made his reputation; this was quite a turnaround given the fact that Vikings had become renowned as scourges of the institution and frequent raiders of monasteries and other religious establishments.
This reflected the fact that these were changing times for the Viking world. Christianity had gained a foothold in much of Europe centuries previously, but was a more recent introduction to the Viking world. Cnut’s family, especially his grandfather Harald Bluetooth, had been patrons of the church. However, Cnut’s reign in England, then one of Europe’s richest countries, allowed him to take this policy to new heights. He was able to make a number of generous gifts to the church and strengthen the fledgling religion in Denmark.
Cnut’s recognition of the church reached its height in 1027, when he journeyed to Rome to attend the coronation of the Holy Roman Emperor, Conrad II. While there he met Pope John XIX. The fact that a Viking ruler could meet the head of the church and be treated as an equal of other mainstream European leaders shows just how much the world had changed.
Did you know?
According to legend, Cnut’s circle of courtiers in England was so convinced of his power that they believed he could control the tides of the sea. Cnut saw this as an opportunity to demonstrate that, despite being king, he was not unaccountable to God. To prove this, he ordered that his throne be carried to the seashore. There, he sat on his throne and proved to his courtiers that he could not make the tides change, and in doing so demonstrated that God held power over everyone on Earth.
When did Cnut die and who was he succeeded by?
Cnut died in Dorset, England, on 12 November 1035. The English crown was succeeded by his son Harold I. Cnut was buried in Winchester, which was the capital of the kingdom of Wessex, and his remains are now held in Winchester Cathedral.
