Cnut the Great (Old Norse: Knútr inn ríki; c. 985 or 995 – 12 November 1035), more commonly known as Canute, was a king of Denmark, England, Norway and parts of Sweden. After the death of his heirs within a decade of his own and the Norman conquest of England in 1066, his legacy was largely lost to history. Historian Norman F. Cantor has made the paradoxical statement that he was "the most effective king in Anglo-Saxon history", despite his not being Anglo-Saxon.
Cnut was of Danish and Slavic descent. His father was Sweyn Forkbeard, King of Denmark (which gave Cnut the patronym Sweynsson, Old Norse Sveinsson). Cnut's mother was the daughter of the first duke of the Polans, Mieszko I; her name may have been Świętosława (see: Sigrid Storråda), but the Oxford DNB article on Cnut states that her name is unknown.
As a prince of Denmark, Cnut won the throne of England in 1016 in the wake of centuries of Viking activity in northwestern Europe. His accession to the Danish throne in 1018 brought the crowns of England and Denmark together. Cnut maintained his power by uniting Danes and Englishmen under cultural bonds of wealth and custom, rather than sheer brutality. After a decade of conflict with opponents in Scandinavia, Cnut claimed the crown of Norway in Trondheim in 1028. The Swedish city Sigtuna was held by Cnut. He had coins struck which called him king there, but there is no narrative record of his occupation.
The kingship of England lent the Danes an important link to the maritime zone between the islands of Great Britain and Ireland, where Cnut, like his father before him, had a strong interest and wielded much influence among the Gall-Ghaedhil.
Cnut's possession of England's dioceses and the continental Diocese of Denmark – with a claim laid upon it by the Holy Roman Empire's Archdiocese of Hamburg-Bremen – was a source of great leverage within the Church, gaining notable concessions from Pope Benedict VIII, and his successor John XIX, such as one on the price of the pallium of his bishops. Cnut also gained concessions on the tolls his people had to pay on the way to Rome from other magnates of medieval Christendom, at the coronation of the Holy Roman Emperor. After his 1026 victory against Norway and Sweden, and on his way to Rome for this coronation, Cnut, in a letter written for the benefit of his subjects, stated himself "king of all England and Denmark and the Norwegians and of some of the Swedes".
Birth and kingship 
Cnut was a son of the Danish Prince Sweyn Forkbeard; his father was the son and heir to King Harald Bluetooth from a line of Scandinavian rulers central to the unification of Denmark. Neither the place nor the date of his birth are known. Harthacnut was the semi-legendary founder of the Danish royal house at the beginning of the tenth century, and his son, Gorm the Old, was the first in the official line (the 'Old' in his name being to this effect). Harald Bluetooth, Gorm's son and Cnut's grandfather, was the Danish king at the time of the Christianization of Denmark. He was the first Scandinavian king to accept Christianity. Cnut's grandfather died when he was 2 and his father became King Sweyn Forkbeard.
Cnut's mother's precise identity is unknown, although it is likely that she was a Slavic princess, daughter to Mieszko I of Poland (in accord with the Monk of St Omer's, Encomium Emmae and Thietmar of Merseburg's contemporary Chronicon). Norse sources of the high medieval period, most prominently Snorri Sturluson's Heimskringla, also give a Polish princess as Cnut's mother, whom they call Gunhild and a daughter of Burislav, the king of Vindland. Since in the Norse sagas the king of Vindland is always Burislav, this is reconcilable with the assumption that her father was Mieszko (not his son Bolesław). Adam of Bremen in Gesta Hammaburgensis ecclesiae pontificum is unique in equating Cnut's mother (for whom he also produces no name) with the former queen of Sweden, wife of Eric the Victorious and by this marriage mother of Olof Skötkonung. To complicate the matter, Heimskringla and other Sagas also have Sweyn marrying Eric's widow, but she is distinctly another person in these texts, by name of Sigrid the Haughty, whom Sweyn only marries after Gunhild, the Slavic princess who bore Cnut, has died. Different theories regarding the number and ancestry of Sweyn's wives (or wife) have been brought forward (see Sigrid the Haughty and Gunhild). But since Adam is the only source to state the identity of Cnut's with Olof Skötkonung's mother, this is often seen as an error of Adam, and it is often assumed that Sweyn had two wives, the first being Cnut's mother, and the second being the former queen of Sweden.
Some hint of Cnut's childhood can be found in the Flateyjarbók, a 13th-century source, stating at one point that Cnut was taught his soldiery by the chieftain Thorkell the Tall, brother to Sigurd, Jarl of mythical Jomsborg, and the legendary Joms, at their Viking stronghold on the Island of Wollin, off the coast of Pomerania. His date of birth, like his mother's name, is unknown. Contemporary works such as the Chronicon and the Encomium Emmae, do not mention it. Even so, in a Knútsdrápa by the skald Óttarr svarti, there is a statement that Cnut was "of no great age" when he first went to war. It also mentions a battle identifiable with Forkbeard's invasion of England, and attack on the city of Norwich, in 1003/04, after the St. Brice's Day massacre of Danes by the English, in 1002. If it is the case that Cnut was part of this, his birthdate may be near 990, or even 980. If not, and the skald's poetic verse envisages another assault, with Forkbeard's conquest of England in 1013/14, it may even suggest a birth date nearer 1000. There is a passage of the Encomiast's (as the author of the Encomium Emmae is known) with a reference to the force Cnut led in his English conquest of 1015/16. Here (see below) it says all the Vikings were of "mature age" under Cnut "the king".
A description of Cnut can be found within the 13th-century Knýtlinga saga:
Knut was exceptionally tall and strong, and the handsomest of men, all except for his nose, that was thin, high-set, and rather hooked. He had a fair complexion none-the-less, and a fine, thick head of hair. His eyes were better than those of other men, both the handsomer and the keener of their sight.
Hardly anything is known for sure of Cnut's life until the year he was part of a Scandinavian force under his father, King Sweyn; with his invasion of England in summer 1013. It was the climax to a succession of Viking raids spread over a number of decades. With their landing in the Humber the kingdom fell to the Vikings quickly, and near the end of the year King Aethelred fled to Normandy, leaving Sweyn in possession of England. In the winter, Forkbeard was in the process of consolidating his kingship, with Cnut left in charge of the fleet, and the base of the army at Gainsborough.
On the death of Forkbeard after a few months as king, on Candlemas Sunday 3 February 1014, Harald succeeded him as King of Denmark, while Cnut was immediately elected king by the Vikings, and the people of the Danelaw. However, the English nobility took a different view, and the Witenagemot recalled Aethelred from Normandy. The restored king swiftly led an army against Cnut, who fled with his army to Denmark, along the way mutilating the hostages they had taken and abandoning them on the beach at Sandwich. Cnut went to Harald and supposedly made the suggestion they might have a joint kingship, although this found no favour with his brother. Harald is thought to have offered Cnut command of his forces for another invasion of England, on the condition he did not continue to press his claim. In any case, Cnut was able to assemble a large fleet with which to launch another invasion.
Conquest of England 
Among the allies of Denmark was Boleslaw the Brave, the Duke of Poland and a relative to the Danish royal house. He lent some Polish troops, likely to have been a pledge made to Cnut and Harald when, in the winter, they "went amongst the Wends" to fetch their mother back to the Danish court. She had been sent away by their father after the death of the Swedish king Eric the Victorious in 995, and his marriage to Sigrid the Haughty, the Swedish queen mother. With this wedlock there was a strong alliance between the successor to the throne of Sweden, Olof Skötkonung, and the rulers of Denmark, his in-laws. Swedes were certainly among the allies in the English conquest. Another in-law to the Danish royal house, Eiríkr Hákonarson, was Trondejarl (Earl of Lade) and the co-ruler of Norway, with his brother Svein Hakonarson – Norway having been under Danish sovereignty since the Battle of Svolder, in 999. Eiríkr's participation in the invasion left his son Hakon to rule Norway, with Svein.
In the summer of 1015, Cnut's fleet set sail for England with a Danish army of perhaps 10,000 in 200 longships. Cnut was at the head of an array of Vikings from all over Scandinavia. The invasion force was to engage in often close and grisly warfare with the English for the next fourteen months. Practically all of the battles were fought against Aethelred's son, Edmund Ironside.
Landing in Wessex 
According to the Peterborough manuscript of the Anglo-Saxon Chronicle, early in September 1015 "[Cnut] came into Sandwich, and straightway sailed around Kent to Wessex, until he came to the mouth of the Frome, and harried in Dorset and Wiltshire and Somerset", beginning a campaign of an intensity not seen since the days of Alfred the Great. A passage from Emma's Encomium provides a picture of Cnut's fleet:
[T]here were so many kinds of shields, that you could have believed that troops of all nations were present. ... Gold shone on the prows, silver also flashed on the variously shaped ships. ... For who could look upon the lions of the foe, terrible with the brightness of gold, who upon the men of metal, menacing with golden face, ... who upon the bulls on the ships threatening death, their horns shining with gold, without feeling any fear for the king of such a force? Furthermore, in this great expedition there was present no slave, no man freed from slavery, no low-born man, no man weakened by age; for all were noble, all strong with the might of mature age, all sufficiently fit for any type of fighting, all of such great fleetness, that they scorned the speed of horsemen.
Wessex, long ruled by the dynasty of Alfred and Aethelred, submitted to Cnut late in 1015, as it had to his father two years earlier. At this point Eadric Streona, the Ealdorman of Mercia, deserted Aethelred together with 40 ships and their crews and joined forces with Cnut. Another defector was Thorkell the Tall, a Jomsviking chief who had fought against the Viking invasion of Sweyn Forkbeard, with a pledge of allegiance to the English in 1012 – some explanation for this shift of allegiance may be found in a stanza of the Jómsvíkinga saga which mentions two attacks against Jomsborg's mercenaries while they were in England, with a man known as Henninge among their casualties, a brother of Thorkell's. If the Flateyjarbók is correct in its statement this man was Cnut's childhood mentor, it explains his acceptance of his allegiance – with Jomvikings ultimately in the service of Jomsborg. The 40 ships Eadric came with, often thought to be of the Danelaw were probably Thorkell's.
Advance into the North 
Early in 1016, the Vikings crossed the Thames and harried Warwickshire, while Aethelred's eldest son Edmund Ironside's attempts at opposition seem to have come to nothing – the chronicler says the English army disbanded because the king and the citizenry of London were not present. Cnut's mid-winter assault devastated its way northwards across eastern Mercia. Another summons of the army brought the Englishmen together, and they were met this time by the king although 'it came to nothing as so often before', and Aethelred returned to London with fears of betrayal. Edmund then went north to join Uhtred the Earl of Northumbria and together harried Staffordshire, Shropshire and Cheshire in western Mercia, possibly targeting the estates of Eadric Streona. Cnut's occupation of Northumbria meant Uhtred returned home to submit himself to Cnut who seems to have sent a Northumbrian rival, Thurbrand the Hold, to massacre Uhtred and his retinue. Eiríkr Hákonarson, most likely with another force of Scandinavians, came to support Cnut at this point, and the veteran Norwegian jarl was put in charge of Northumbria.
In London, still unsubdued behind its famous walls, Edmund was elected king after the death of Aethelred on 23 April 1016.
Siege of London 
Cnut returned southward and the Danish army evidently divided, some dealing with Edmund – who had broken out of London before Cnut's encirclement of the city was complete and gone to gather an army in Wessex, the traditional heartland of the English monarchy – some besieging London – with the construction of dikes on the northern and southern flanks and a channel dug across the banks of the Thames to the south of the city for the longships to cut off communications up-river.
There was a battle fought at Penselwood, in Somerset – with a hill in Selwood Forest as the likely location – and a subsequent battle at Sherston, in Wiltshire, which was fought over two days but left neither side victorious.
Edmund was able to temporarily relieve London, driving the enemy away and defeating them after crossing the Thames at Brentford. Suffering heavy losses he withdrew to Wessex to gather fresh troops, and the Danes again brought London under siege, but after another unsuccessful assault themselves withdrew into Kent under attack by the English, with a battle fought at Otford. At this point Eadric Streona went over to Edmund, and Cnut set sail northwards across the sea to Essex, and from the landing of the ships up the River Orwell went to ravage Mercia.
London captured by treaty 
On 18 October 1016, as the Danes retired towards their ships they were engaged by Edmund's army, leading to the Battle of Assandun - fought at either Ashingdon, in south-east, or Ashdon, in north-west Essex. In the ensuing struggle, Eadric Streona, whose return to the English side had perhaps only been a ruse, withdrew his forces from the fray, bringing about a decisive English defeat. Edmund fled westwards and Cnut went after him into Gloucestershire, with another battle probably fought near the Forest of Dean – for Edmund had an alliance with some of the Welsh.
On an island near Deerhurst Cnut and Edmund - who had been wounded - met to negotiate terms of peace. It was agreed all of England north of the Thames was to be the domain of the Danish prince, while all to the south was kept by the English king, along with London. Accession to the reign of the entire realm being set to pass to Cnut upon Edmund's death. Edmund died on 30 November, within weeks of the agreement. Some sources claim Edmund was murdered, although the circumstances of his death are unknown. In accord with his treaty with Ironside, Cnut was left as king of all England. His coronation was in London, at Christmas, with recognition by the nobility in January the next year at Oxford.
King of England 
Cnut was to rule England for almost twenty years. The protection he lent against Viking raiders – with many of them under his command – restored the prosperity that had been increasingly impaired since the resumption of Viking attacks in the 980s. The resources he commanded in England helped him to establish control of the majority of Scandinavia too.
Consolidation and Danegeld 
In July 1017, Cnut wed Emma of Normandy, the widow of Aethelred, and daughter of Richard the Fearless, the first Duke of Normandy. With Edmund dead, Cnut was quick to eliminate any prospective challenge from the survivors of the Wessex dynasty. The first year of his reign was marked by the executions of a number of English noblemen whom he considered suspect. Aethelred's son Eadwig fled from England but was killed on Cnut's orders. Edmund Ironside's sons Edward and Edmund likewise fled abroad, Edward eventually to Hungary. Emma's sons by Aethelred, Edward the Confessor and Alfred Atheling went into exile among their relatives in Normandy. Cnut put forward Harthacnut, his son by Emma, to be his heir; Svein Knutsson and Harold Harefoot, his two sons from his marriage to Ælfgifu of Northampton, his handfast wife, were kept on the sidelines.
In 1018, having collected a Danegeld amounting to the colossal sum of £72,000 levied nationwide, with an additional £10,500 extracted from London, Cnut paid off his army and sent most of them home. He retained 40 ships and their crews as a standing force in England. An annual tax called heregeld (army payment) was collected through the same system Aethelred had instituted in 1012 to reward Scandinavians in his service
Cnut extended the existing trend for multiple shires to be grouped together under a single ealdorman, dividing the country into four large administrative units whose geographical extent was based on the largest and most durable of the separate kingdoms which had preceded the unification of England. The officials responsible for these provinces were designated earls, a title of Scandinavian origin already in localised use in England which now everywhere replaced that of ealdorman. Wessex was initially kept under Cnut's personal control, while Northumbria went to Erik of Hlathir, East Anglia to Thorkell the Tall, and Mercia remained in the hands of Eadric Streona.
This initial distribution of power was short-lived. The chronically treacherous Eadric was executed within a year of Cnut's accession. Mercia passed to one of the leading families of the region, probably first to Leofwine, ealdorman of the Hwicce under Aethelred, but certainly soon to his son Leofric. In 1021 Thorkel the Tall also fell from favour and was outlawed. Following the death of Erik in the 1020s, he was succeeded as Earl of Northumbria by Siward, whose grandmother, Estrid (married to Úlfr Thorgilsson), was Cnut's sister. Bernicia, the northern part of Northumbria, was theoretically part of Erik and Siward's earldom but throughout Cnut's reign it effectively remained under the control of the English dynasty based at Bamburgh who had dominated the area at least since the early tenth century. They served as junior Earls of Bernicia under the titular authority of the Earl of Northumbria. By the 1030s Cnut's direct administration of Wessex had come to an end, with the establishment of an earldom under Godwin, an Englishman from a powerful Sussex family. In general, after initial reliance on his Scandinavian followers in the first years of his reign, Cnut allowed those Anglo-Saxon families of the existing English nobility who had earned his trust to assume rulership of his Earldoms.
Affairs to the East 
At the Battle of Nesjar, in 1016, Olaf Haraldsson won the kingdom of Norway from the Danes. It was at some time after Eirkr left for England, and on the death of Svein while retreating to Sweden, maybe intent on returning to Norway with reinforcements, Erikr's son Hakon went to join his father and support Cnut in England too.
Cnut's brother Harald was possibly at Cnut's coronation, in 1016, with his return to Denmark, as its king, with part of the fleet, at some point thereafter. It is only certain, though, there was an entry of his name, alongside Cnut's, in confraternity with Christ Church, Canterbury, in 1018. This, though, is not conclusive, for the entry may have been made in Harald's absence, by the hand of Cnut himself even, which means, while it is usually thought that Harald died in 1018, it is unsure if he was even alive to do this. Entry of his brother's name in the Canterbury codex may have been Cnut's attempt to make his vengeance for Harald's murder good with the Church. Of course, this was maybe just a gesture for a soul to be under God's protection. There is evidence Cnut was in battle with pirates in 1018, with his destruction of the crews of thirty ships, although it is unknown if this was off the English or Danish shores. He himself mentions troubles in his 1019 letter (to England, from Denmark), written as the King of England and Denmark. These events can be seen, with plausibility, to be in connection with the death of Harald. Cnut says he dealt with dissenters to ensure Denmark was free to assist England:
King Cnut greets in friendship his archbishop and his diocesan bishops and Earl Thurkil and all his earls... ecclesiatic and lay, in England... I inform you that I will be a gracious lord and a faithfull observer of God's rights and just secular law. (He exhorts his ealdormen to assist the bishops in the maintenance of) God's rights... and the benefit of the people.
If anyone, ecclesiastic or layman, Dane or Englishman, is so presumptuous as to defy God's law and my royal authority or the secular laws, and he will not make amends and desist according to the direction of my bishops, I then pray, and also command, Earl Thurkil, if he can, to cause the evil-doer to do right. And if he cannot, then it is my will that with the power of us both he shall destroy him in the land or drive him out of the land, whether he be of high or low rank. And it is my will that all the nation, ecclesiatical and lay, shall steadfastly observe Edgar's laws, which all men have chosen and sworn at Oxford.
Since I did not spare my money, as long as hostility was threatening you, I with God's help have put an end to it. Then I was informed that greater danger was approaching us than we liked at all; and then I went myself with the men who accompanied me to Denmark, from where the greatest injury had come to us, and with God's help I have made it so that never henceforth shall hostility reach you from there as long as you support me rightly and my life lasts. Now I thank Almighty God for his help and his mercy, that I have settled the great dangers which were approaching us that we need fear no danger to us from there; but we may rekon on full help and deliverance, if we need it—Cnut's letter of 1019
Cnut was generally remembered as a wise and successful king of England, although this view may in part be attributable to his good treatment of the Church, keeper of the historic record. Accordingly, we hear of him, even today, as a religious man (see below), despite the fact that he was in an arguably sinful relationship, with two wives, and the harsh treatment he dealt his fellow Christian opponents.
Under his reign, Cnut brought together the English and Danish kingdoms, and the people saw a golden age of dominance across Scandinavia, as well as within the British Isles. His campaigns abroad meant the tables of Viking supremacy were stacked in favour of the English, turning the prows of the longships towards Scandinavia. He reinstated the Laws of King Edgar to allow for the constitution of a Danelaw, and the activity of Scandinavians at large. He also reinstituted the extant laws with a series of proclamations to assuage common grievances brought to his attention. Two significant ones were: On Inheritance in case of Intestacy, and, On Heriots and Reliefs. He strengthened the currency, initiating a series of coins of equal weight to those being used in Denmark and other parts of Scandinavia.
King of Denmark 
In 1018, Harald II died and Cnut went to Denmark to affirm his succession to the Danish crown as Cnut II. In the 1019 letter (see above) he states his intentions to avert attacks against England. It seems there were Danes in opposition to him, and an attack he carried out on the Wends of Pomerania may have had something to do with this. In this expedition at least one of Cnut's English men, Godwin, apparently won the king's trust after a night-time raid he personally led against a Wendish encampment.
His hold on the Danish throne presumably stable, Cnut was back in England in 1020. Ulf Jarl, the husband of his sister Estrid Svendsdatter, was his appointee as regent of Denmark, with the entrustment of his young son by Queen Emma, Harthacnut, whom he had made the crown prince of his kingdom.
Thorkell the Tall's banishment in 1021 may be seen in relation to the attack on the Wends for the death of Olof Skötkonung in 1022, and the succession to the Swedish throne of his son, Anund Jacob, bringing Sweden into alliance with Norway. Thus, there was cause for a demonstration of Danish strength in the Baltic. Jomsborg, the legendary stronghold of the Jomsvikings, thought to be on an island off the coast of Pomerania, was probably the target of Cnut's expedition. After this clear display of Cnut's intentions to dominate Scandinavian affairs, it seems Thorkell reconciled with Cnut in 1023.
When Olaf Haraldsson and Anund Jakob took advantage of Cnut's commitment to England and began to launch attacks against Denmark, Ulf gave the freemen cause to accept Harthacnut, still a child, as king. This was a ruse on Ulf's part since the role he had as the caretaker of Harthacnut consequently gave him the reign of the kingdom. Upon news of these events Cnut set sail for Denmark, to restore himself and deal with Ulf, who then got back in line. In a battle known as the Battle of the Helgeå, Cnut and his men fought the Norwegians and Swedes at the mouth of the river Helgea. 1026 is the likely date for the battle, and the apparent victory left Cnut as the dominant leader in Scandinavia. Ulf the usurper's realignment and participation in the battle did not, in the end, earn him Cnut's forgiveness. Some sources state, at a banquet in Roskilde, the brothers-in-law were playing chess when an argument arose between them, and the next day, Christmas of 1026, one of Cnut's housecarls, with his blessing, killed the jarl, in Trinity Church, the predecessor to Roskilde Cathedral.
Journey to Rome 
His enemies in Scandinavia subdued, and apparently at his leisure, Cnut was able to accept an invitation to witness the accession of the Holy Roman Emperor Conrad II. He left his affairs in the north, and went from Denmark to the coronation of the King of the Romans, at Easter 1027, in Rome – a pilgrimage of considerable prestige for rulers of Europe in the Middle Ages, to the heart of Christendom.
On the return journey his letter of 1027, like his letter of 1019, was written to inform his subjects in England of his intentions from abroad. It is in this letter he proclaims himself ‘king of all England and Denmark and the Norwegians and of some of the Swedes’.
Consistent with his role as a Christian king, Cnut says he went to Rome to repent for his sins, pray for redemption and the security of his subjects, and negotiate with the Pope for a reduction in the costs of the pallium for English archbishops, and for a resolution to the competition of the archdioceses of Canterbury, and Hamburg-Bremen, for superiority over the Danish dioceses. He also sought to improve the conditions for pilgrims, as well as merchants, on the road to Rome. In his own words:
... I spoke with the Emperor himself and the Lord Pope and the princes there about the needs of all people of my entire realm, both English and Danes, that a juster law and securer peace might be granted to them on the road to Rome and that they should not be straitened by so many barriers along the road, and harassed by unjust tolls; and the Emperor agreed and likewise King Robert who governs most of these same toll gates. And all the merchants confirmed by edict that my people, both merchants, and the others who travel to make their devotions, might go to Rome and return without being afflicted by barriers and toll collectors, in firm peace and secure in a just law.—Cnut's letter of 1027
"Robert" in Cnut's text is probably a clerical error for Rudolph, the last ruler of an independent Kingdom of Burgundy. Hence, the solemn word of the Pope, the Emperor, and Rudolph, was given with the witness of four archbishops, twenty bishops, and 'innumerable multitudes of dukes and nobles'. This suggests it was before the ceremonies were at an end. It is without doubt Cnut threw himself into his role with zest. His image as the just Christian king, statesman and diplomat, and crusader against unjustness, seems to be one with its roots in reality, as well as one he sought to project.
A good illustration of his status within Europe is the fact Cnut, and the King of Burgundy went alongside the emperor in the imperial procession, and stood shoulder to shoulder with him on the same pedestal. Cnut and the emperor, in accord with various sources, took one another's company like brothers, for they were of a similar age. Conrad gave Cnut lands in the Mark of Schleswig—the land-bridge between the Scandinavian kingdoms and the continent—as a token of their treaty of friendship. Centuries of conflict in this area between the Danes and the Germans was the cause for the construction of the Danevirke, from Schleswig, on the Schlei, an inlet of the Baltic Sea, to the North Sea.
His visit to Rome was a triumph. In the verse of Knútsdrápa, Sigvatr Þórðarson praises Cnut, his king, as being "dear to the Emperor, close to Peter". In the days of Christendom, a king seen to be in favour with God could expect to be ruler over a happy kingdom. He was surely in a stronger position, not only with the Church, and the people, but with the alliance with his southern rivals he was able to conclude his conflicts with his rivals in the north. His letter not only tells his countrymen of his achievements in Rome, but also of his ambitions within the Scandinavian world at his arrival home:
... I, as I wish to be made known to you, returning by the same route that I took out, am going to Denmark to arrange peace and a firm treaty, in the counsel of all the Danes, with those races and people who would have deprived us of life and rule if they could, but they could not, God destroying their strength. May he preserve us by his bounteous compassion in rule and honour and henceforth scatter and bring to nothing the power and might of all our enemies! And finally, when peace has been arranged with our surrounding peoples and all our kingdom here in the east has been properly ordered and pacified, so that we have no war to fear on any side or the hostility of individuals, I intend to come to England as early this summer as I can to attend to the equipping of a fleet.—Cnut's letter of 1027
Cnut was to return to Denmark from Rome, arrange for some kind of pact with the peoples of Scandinavia, and afterwards sail to England.
King of Norway and part of Sweden 
In the 1027 letter, Cnut considers himself King of all England and Denmark, and the Norwegians, and of some of the Swedes – victory over Swedes suggests Helgea to be the river in Uppland and not the one in eastern Scania, while Sweden's king appears to have been made a renegade. He also stated his intention of proceeding to Denmark, for the securing of a peace between the kingdoms of Scandinavia, which fits John of Worcester's writing that in 1027 Cnut heard some Norwegians were discontented and sent them sums of gold and silver to gain their support in his claim on the throne.
In 1028, after his return from Rome, through Denmark, Cnut set off from England with a fleet of fifty ships, to Norway, and the city of Trondheim. Olaf Haraldsson stood down, unable to put up any fight, as his nobles were against him for a tendency to flay their wives for sorcery. Cnut was crowned king, now of England and Denmark, and Norway (he was not King of Sweden, only some of the Swedes). He entrusted the Earldom of Lade to the former line of earls, in Håkon Eiriksson, with Earl Eiríkr Hákonarson probably dead at this date. Hakon was possibly the Earl of Northumbria after Erik too.
Hakon, a member of a family with a long tradition of hostility towards the independent Norwegian kings, and a relative of Cnut's, was already in lordship over the Isles, with the earldom of Worcester, possibly from 1016–17. The sea-lanes through the Irish Sea and Hebrides, led to Orkney and Norway, and were central to Cnut's ambitions for dominance of Scandinavia, as well as the British Isles. Hakon was meant to be Cnut's lieutenant of this strategic chain. And the final component was his installation as the king's deputy in Norway, after the expulsion of Olaf Haraldsson in 1028. Hakon, though, died in a shipwreck in the Pentland Firth, between the Orkneys and the Scottish mainland, either late 1029 or early 1030.
Upon the death of Hakon, Olaf Haraldsson was to return to Norway, with Swedes in his army. He, though, was to meet his death at the hands of his own people, at the Battle of Stiklestad, in 1030. Cnut's subsequent attempt to rule Norway without the key support of the Trondejarls, through Ælfgifu of Northampton, and his eldest son by her, Sweyn Knutsson, was not a success. It is known as Aelfgifu's Time in Norway, with heavy taxation, a rebellion, and the restoration of the former Norwegian dynasty under Saint Olaf's illegitimate son Magnus the Good.
Influence in the western sea-ways 
At the Battle of Clontarf on 23 April 1014—even as Cnut was preparing his re-invasion of England—there was an epic array of armies laid out on the fields before the walls of Dublin. Máel Mórda, king of Leinster, and Sigtrygg Silkbeard, ruler of the Norse-Gaelic kingdom of Dublin, had sent out emissaries to all the Viking kingdoms to request assistance in their rebellion against Brian Bóruma, the High King of Ireland. Sigurd the Stout, the Earl of Orkney, was offered command of all the Norse forces. Likewise, the High King had sought assistance from the Albannaich, who were led by Domhnall Mac Eiminn Mac Cainnich, Mormaer of Ce (Marr & Buchan).
The Leinster-Norse alliance was defeated, with both commanders, Sigurd and Máel Mórda, being killed. However, Brian, his son, his grandson, and the Mormaer Domhnall were slain too. Sigtrygg's alliance was broken, although he was left alive, and the high-kingship of Ireland went back to the Uí Néill, again under Máel Sechnaill mac Domnaill.
There was a brief period of freedom in the Irish Sea zone for the Vikings of Dublin with a political vacuum felt throughout the entire Western Maritime Zone of the North Atlantic Archipelago, and prominent among those who stood to fill it was Cnut, "whose leadership of the Scandinavian world gave him a unique influence over the western colonies and whose control of their commercial arteries gave an economic edge to political domination". A strong piece of evidence for Dublin's involvement with Cnut is that its king, Silkbeard, struck coinage of Cnut's quatrefoil type—in issue c. 1017–25 – sporadically replacing the legend with one bearing his own name and styling him as ruler either 'of Dublin' or 'among the Irish'. Another is the entry of one Sihtric dux in three of Cnut's charters.
In one of his verses, Cnut's court poet Sigvatr Þórðarson recounts that famous princes brought their heads to Cnut and bought peace. This verse mentions Olaf Haraldsson in the past tense, with his death at the Battle of Stiklestad, in 1030. It was therefore at some point after this, and the consolidation of Norway, Cnut went to Scotland, with an army, and the navy in the Irish Sea, in 1031, to receive, without bloodshed, the submission of three Scottish kings: Maelcolm, Maelbeth, and Iehmarc. One of these kings, Iehmarc, may be one Echmarcach mac Ragnaill, an Uí Ímair chieftain, and the ruler of a sea-kingdom of the Irish Sea, with Galloway among his domains. Furtherly, a Lausavísa attributable to the skald Óttarr svarti greets the ruler of the Danes, Irish, English and Island-dwellers – use of Irish here being likely to mean the Gall Ghaedil kingdoms, rather than the Gaelic kingdoms too, while it "brings to mind Sweyn Forkbeard's putative activities in the Irish Sea and Adam of Bremen's story of his stay with a rex Scothorum (? king of the Irish) [&] can also be linked to... Iehmarc, who submitted in 1031 [&] could be relevant to Cnut's relations with the Irish".
Relations with the Church 
Cnut's actions as a Viking conqueror had made him uneasy with the Church. He was already a Christian before he was king – being named Lambert at his baptism – although the Christianization of Scandinavia was not at all complete in his day. His ruthless treatment of the overthrown dynasty, as well as his open relationship with a concubine—Ælfgifu of Northampton, his handfast wife, whom he kept as his northern queen when he wed Emma of Normandy, confusingly also Ælfgifu in Old English, who was kept in the south, with an estate in Exeter— was a bone of contention, to say the least. It was important for him to reconcile himself with his churchmen, and he made considerable efforts to do so. In this effort Cnut repaired all the English churches and monasteries that were victims of the Viking love for plunder, and refilled their coffers. He also built new churches and was an earnest patron of monastic communities. His homeland of Denmark was a Christian nation on the rise, and the desire to enhance the religion still fresh. As an example, the first stone church recorded to have been built in Scandinavia, was in Roskilde c. 1027, and its patron was Cnut's sister Estrid.
It is hard to conclude if Cnut's attitude towards the Church came out of deep religious devotion, or merely as a means to reinforce his regime's hold on the people. There is evidence of a respect for the Viking religion in his praise poetry, which he was happy enough for his skalds to embellish in Norse mythology, while other Viking leaders were insistent on the rigid observation of the Christian line, like St Olaf. We see too the desire for a respectable Christian nationhood within Europe. In 1018, some sources suggest he was at Canterbury on the return of its Archbishop Lyfing from Rome, to receive letters of exhortation from the Pope. If this chronology is correct, he probably went from Canturbury to the Witan at Oxford, with Archbishop Wulfstan of York in attendance to record the event.
Cnut's ecumenical gifts were widespread and often exuberant. Commonly land was given, exemption from taxes, as well as relics. Christ Church was probably given rights at the important port of Sandwich as well as tax exemption, with confirmation in the placement of their charters on the altar, while it got the relics of St Ælfheah, which was at the displeasure of the people of London. Another see in the king's favour was Winchester, second only to the Canturbury see in terms of its wealth. New Minster's Liber Vitae records Cnut as a benefactor of the monastery, and the Winchester Cross, with 500 marks of silver and 30 marks of gold in, as well as relics of various saints was given to it. Old Minster was the recipient of a shrine for the relics of St Birinus and the probable confirmation of its privileges. The monastery at Evesham, with its Abbot Ælfweard purportedly a relative of the king through Ælfgifu the Lady (probably Ælfgifu of Northampton, rather than Queen Emma, also known as Ælfgifu), got the relics of St Wigstan. Cnut's generosity towards his subjects, a thing his skalds called destroying treasure, was of course popular with the English. Still, it is important to remember not all Englishmen were in his favour, and the burden of taxation was widely felt. His attitude towards London's see was clearly not benign. The monasteries at Ely and Glastonbury were apparently not on good terms either. Other gifts were also given to his neighbours. Among these were a gift to Chartres, of which its bishop wrote, "When we saw the gift that you sent us, we were amazed at your knowledge as well as your faith ... since you, whom we had heard to be a pagan prince, we now know to be not only a Christian, but also a most generous donor to God's churches and servants". He is known to have sent a psalter and sacramentary made in Peterborough, famous for its illustrations, to Cologne, and a book written in gold, among other gifts, to William the Great of Aquitaine. This golden book was apparently to support Aquitanian claims of St Martial, patron saint of Aquitaine, as an apostle. Of some consequence, its recipient was an avid artisan, scholar, and devout Christian, and the Abbey of Saint-Martial was a great library and scriptorium, second only to the one at Cluny. It is probable that Cnut's gifts were well beyond anything we can now prove.
Cnut’s journey to Rome in 1027 is another sign of his dedication to the Christian religion. It may be that he went to attend Emperor Conrad II’s coronation in order to improve relations between the two powers, yet he had made a vow previously to seek the favour of St Peter, the keeper of the keys to the heavenly kingdom. While in Rome, Cnut made an agreement with the Pope to reduce the fees paid by the English archbishops to receive their pallium. He also arranged that travelers from his realm should pay reduced or no tolls, and that they should be safeguarded on their way to and from Rome. Some evidence exists for a second journey in 1030.
Death and succession 
Cnut died in 1035, at the Abbey in Shaftesbury, Dorset. His burial was in Winchester, the English capital of the time, and stronghold of the royal house of Wessex, whom the Danes had overthrown more or less two decades before.
In Denmark he was succeeded by Harthacnut, reigning as Cnut III, although with a war in Scandinavia against Magnus I of Norway, Harthacnut was "forsaken [by the English] because he was too long in Denmark", and his mother Queen Emma, previously resident at Winchester with some of her son's housecarls, was made to flee to Bruges, in Flanders; under pressure from supporters of Cnut's other son – after Svein – by Ælfgifu of Northampton. Harold Harefoot – regent in England 1035–37 – succeeded to claim the throne, in 1037, reigning until his death in 1040. Eventual peace in Scandinavia left Harthacnut free to claim the throne himself, in 1040, and regain his mother her place. He brought the crowns of Denmark and England together again, until his death, in 1042. Denmark fell into a period of disorder with the power struggle between the pretender to the throne Sweyn Estridsson, son of Ulf, and the Norwegian king, until Magnus' death in 1047 and restoration of the Danish sovereignty. And the inheritance of England was briefly to return to its Anglo-Saxon lineage.
The house of Wessex was to reign again in Edward the Confessor, whom Harthacnut his half-brother - had brought out of exile in Normandy and made a treaty with. Like in his treaty with Magnus, it was decreed the throne was to go to Edward if Harthacnut died with no legitimate male heir. In 1042, Harthacnut died, and Edward was king. His reign meant Norman influence at Court was on the rise thereafter, and the ambitions of its dukes finally found fruition in 1066, with William the Conqueror's invasion of England, and crowning, fifty years after Cnut was crowned in 1016.
Had the sons of Cnut not died within a decade of him, and his (only known) daughter Cunigund – set to marry Conrad II's son Henry III eight months after his death – not died in Italy before she became empress, Cnut's reign might well have been the foundation for a complete political union between England and Scandinavia.
Bones at Winchester 
The new regime of Normandy was keen to signal its arrival with an ambitious programme of grandiose cathedrals and castles throughout the High Middle Ages. Winchester Cathedral was built on the old Anglo-Saxon site (Old Minster) and the previous burials were set in mortuary chests there. Then, during the English Civil War, in the 17th century, plundering Roundhead soldiers scattered the bones on the floor, and the bones of Cnut were spread amongst the various other chests of rulers: notably William Rufus. After the restoration of the monarchy, the bones were collected and replaced randomly in their chests.
Marriages and children 
- 1 – Ælfgifu of Northampton
- 2 – Emma of Normandy
Family tree 
+Said to have been a great-granddaughter of Cnut's grandfather Harald Bluetooth, but this was probably a fiction intended to give her a royal bloodline.
Ruler of the waves 
Henry of Huntingdon, the 12th-century chronicler, tells how Cnut set his throne by the sea shore and commanded the tide to halt and not wet his feet and robes. Yet "continuing to rise as usual [the tide] dashed over his feet and legs without respect to his royal person. Then the king leapt backwards, saying: 'Let all men know how empty and worthless is the power of kings, for there is none worthy of the name, but He whom heaven, earth, and sea obey by eternal laws.' He then hung his gold crown on a crucifix, and never wore it again "to the honour of God the almighty King". This incident is usually misrepresented by popular commentators and politicians as an example of Cnut's arrogance.
This story may be apocryphal. While the contemporary Encomium Emmae has no mention of it, it would seem that so pious a dedication might have been recorded there, since the same source gives an "eye-witness account of his lavish gifts to the monasteries and poor of St Omer when on the way to Rome, and of the tears and breast-beating which accompanied them". Goscelin, writing later in the 11th century, instead has Cnut place his crown on a crucifix at Winchester one Easter, with no mention of the sea, and "with the explanation that the king of kings was more worthy of it than he". Nevertheless, there may be a "basis of fact, in a planned act of piety" behind this story, and Henry of Huntingdon cites it as an example of the king's "nobleness and greatness of mind." Later historians repeated the story, most of them adjusting it to have Cnut more clearly aware that the tides would not obey him, and staging the scene to rebuke the flattery of his courtiers; and there are earlier Celtic parallels in stories of men who commanded the tides, namely Saint Illtud, Maelgwn, king of Gwynedd, and Tuirbe, of Tuirbe's Strand, in Brittany.
The encounter with the waves is said to have taken place at Thorn-eye (Thorn Island), or Southampton in Hampshire. There were and are numerous islands so named, including at Westminster and Bosham in West Sussex, both places closely associated with Cnut. According to the House of Commons Information Office, Cnut set up a royal palace during his reign on Thorney Island (later to become known as Westminster) as the area was sufficiently far away from the busy settlement to the east known as London. It is believed that, on this site, Cnut tried to command the tide of the river to prove to his courtiers that they were fools to think that he could command the waves. Conflictingly, a sign on Southampton city centre's Canute Road reads, "Near this spot AD 1028 Canute reproved his courtiers".
Cnut's skalds 
The Old Norse catalogue of skalds known as Skáldatal lists eight skalds who were active at Cnut's court. Four of them, namely Sigvatr Þórðarson, Óttarr svarti, Þórarinn loftunga and Hallvarðr háreksblesi, composed verses in honour of Cnut which have survived in some form, while no such thing is apparent from the four other skalds Bersi Torfuson, Arnórr Þórðarson jarlaskáld (known from other works), Steinn Skaptason and Óðarkeptr (unknown). The principal works for Cnut are the three Knútsdrápur by Sigvatr Þórðarson, Óttarr svarti and Hallvarðr háreksblesi, and the Höfuðlausn and Tøgdrápa by Þórarinn loftunga. Cnut also features in two other contemporary skaldic poems, namely Þórðr Kolbeinsson's Eiríksdrápa and the anonymous Liðsmannaflokkr.
Cnut's skalds emphasize the parallelism between Cnut's rule of his earthly kingdom and God's rule of Heaven. This is particularly apparent in their refrains. Thus the refrain of Þórarinn's Höfuðlausn translates to "Cnut protects the land as the guardian of Byzantium [God] [does] Heaven" and the refrain of Hallvarðr's Knútsdrápa translates to "Cnut protects the land as the Lord of all [does] the splendid hall of the mountains [Heaven]". Despite the Christian message, the poets also make use of traditional pagan references and this is particularly true of Hallvarðr. As an example, one of his half-stanzas translates to "The Freyr of the noise of weapons [warrior] has also cast under him Norway; the battle-server [warrior] diminishes the hunger of the valcyrie's hawks [ravens]." The skald here refers to Cnut as "Freyr of battle", a kenning using the name of the pagan god Freyr. References of this sort were avoided by poets composing for the contemporary kings of Norway but Cnut seems to have had a more relaxed attitude towards pagan literary allusions.

- Cnut's mother is the subject of historical debate. Some sources identify as her Gunnhilda, others say she is apocryphal or that there is insufficient evidence to name her. According to Medieval chroniclers Thietmar of Merseburg and Adam of Bremen, Cnut was the son of a Polish princess who was the daughter of Mieszko I and sister of Boleslaw I: this has been linked to Cnut's use of Polish troops in England and Cnut's sister's Anglicized Slavic name, Santslaue.
