One of only two British monarchs to be given the epithet “the Great” (the other was Alfred the Great), Cnut was King of England, Denmark, and Norway and together his dominions were called the North Sea Empire. He was born circa 995 in Denmark, the elder son of Sweyn Forkbeard, then King of Denmark and Norway, later also King of England. Sweyn Forkbeard had two wives: Sigrid Storråda (the Haughty) and Gunhilda of Wenden. Both women are mentioned in the Norse sagas but there is very little information about them in the medieval chronicles. Sweyn Forkbeard had seven known children but which of the two women are their mothers is uncertain. It is probable that Gunhilda of Wenden was the mother of Cnut and his brother Harald.

Cnut had six known siblings:

Hardly anything is known about Cnut until 1013 when he was part of an army under his father Sweyn Forkbeard in his invasion of England. This was a culmination of Sweyn Forkbeard’s raids in England since 1003. According to The Anglo-Saxon Chronicle, in 1002 Æthelred II, King of the English was told that the Danish men in England “would faithlessly take his life, and then all his councilors, and possess his kingdom afterward.” In response, Æthelred “ordered slain all the Danish men who were in England.” St. Brice’s Day Massacre occurred on November 13, 1002. There was a significant loss of life including Gunhilde, the sister of Sweyn Forkbeard. In retaliation, Sweyn attacked England during 1003 – 1004 but famine in 1005 caused him to retreat. The Danish invaders returned and within a few years, all of England came under Danish rule. On Christmas Day in 1013, Sweyn was formally proclaimed King of England. Æthelred II had fled to the Isle of Wight and then to Normandy.

However, Sweyn Forkbeard’s reign was short-lived as he suddenly died on February 3, 1014. Sweyn’s younger son succeeded him as Harald II, King of Denmark, and his elder son Cnut, was proclaimed King of England by the Danes in England. However, English noblemen sent a deputation to Æthelred II to negotiate his restoration to the throne. Æthelred returned from exile in Normandy in the spring of 1014, managed to drive Cnut out of England, and then reigned until his death on April 23, 1016.

Æthelred II’s son Edmund Ironside became King of the English but had to fight Cnut to keep the Kingdom of England. He earned the added name “Ironside” because of his bravery in resisting the Danish invasion led by Cnut the Great. The war between Edmund and Cnut ended in a decisive victory for Cnut at the Battle of Assandun on October 18, 1016. Because Edmund’s reputation as a warrior was great, Cnut agreed to divide England, with Edmund taking Wessex and Cnut the rest of the country beyond the River Thames. However, Edmund died on November 30, 1016, and Cnut the Great became King of England. Cnut succeeded his brother Harald II as King of Denmark in 1019. In 1029, Cnut invaded Norway and when King Olaf II of Norway was killed in 1030 at the Battle of Stiklestad, Cnut became King of Norway. He eventually also ruled parts of Sweden, Pomerania, and Schleswig.

Cnut’s first wife was Ælfgifu of Northampton, daughter of Ælfhelm, Ealdorman of Northumbria. In 1006, her father and brothers came under suspicion of consorting with the Danes in northern England. Her father was murdered and her brothers were blinded, probably at the command of Æthelred II. When Sweyn Forkbeard invaded England, the people of the north, many of them of Scandinavian descent, immediately submitted to him. He then married his son Cnut to Ælfgifu to seal their loyalty.

After Cnut’s conquest of England in 1016, he married Emma of Normandy, the widow of King Æthelred II. At that time, it was acceptable to put aside one wife and take another. Exactly how Cnut’s second marriage affected Ælfgifu’s status is unknown but there is no evidence to suggest that she was repudiated. In fact, in 1030, after the defeat and death of King Olaf II of Norway by forces loyal to Cnut, Cnut sent Ælfgifu with their eldest son Sweyn to govern Norway. Their rule was considered oppressive by the Norwegians and they were expelled in 1035.  Magnus the Good, a son of Olaf II, then became King of Norway. There are no records of Ælfgifu after 1036 but it is unknown when she died.

Cnut and Ælfgifu had two sons:

In 1017, Cnut thought it would be expedient to marry Æthelred II’s widow and sent for Emma of Normandy, a daughter of Richard I, Duke of Normandy. It is unclear whether Emma married Cnut by force or if she chose to accept Cnut’s proposal but she returned to England from Normandy and married Cnut.

Emma and Cnut had two children:

Emma’s children by Æthelred II remained in exile in Normandy:

Emma and Cnut’s marriage had begun as a loveless, political strategy but Emma’s importance in the affairs of the kingdom grew. Chroniclers often mentioned that Emma was alongside her husband as if they were inseparable from each other one. After Cnut became King of Denmark in 1019 and King of Norway in 1028, it was often necessary for him to be absent from England and Emma assumed a form of regency during those periods with the main nobles of the kingdom and the Archbishops of Canterbury and York.

Cnut the Great died on November 12, 1035, when he was about 40-years-old. He was buried at the Old Minster in Winchester. When the Old Minster was demolished in 1093, Canute’s remains were moved to Winchester Cathedral. They are among the remains in the mortuary chests that rest on top of the choir screen. Cnut was succeeded in England by Harold Harefoot, his son from his first marriage to Ælfgifu of Northampton, and in Denmark by Harthacnut, his son from his second marriage to Emma of Normandy.
