Knud II den Store (995-1035), King of England (1014-1035), King of Denmark (1018-1035), and King of Norway (1028-1035).
The pirate empire developed by the kings of Denmark, namely the North Sea Empire, finally reached its peak in the hands of Knut.
He is the grandson of Harar Bluetooth king and the second son of the king of Svan-Beard. In 1014, King Svan's eight-letter beard conquered most of England and became the first Dane recognized by the English as king.

Knut was the real hegemon of Northwestern Europe at that time, and the man of the age of Norman conquest. He made Denmark reach its zenith, known as "Knut the Great" in history.
Sifan left two sons:
Halal and Knut, brothers split up the empire of their father. Halal became king of Denmark and Knut became king of England.
However, the descendants of Alfred the Great, who were respected by the people of England, refused the Danish Knut to be their king, and Knut was forced to return to Denmark.
The next year (1015), with the support of his brother, he led a fleet of 200 pirate ships to England, and got the help of the Yums Viking soldiers. The two sides fought a fierce battle with each other.
Because the Danish pirates were brave and brave, they finally defeated the English, but failed to completely make the English surrender.
In 1016, he reached an agreement with the British:
Britain is divided into two parts by the Thames River. He is divided with Edmund II, the descendant of Alfred, and the one who died first between the two kings will give his land to another living king, whose descendants will rule the whole of Britain.
This is also the last large-scale expedition in the history of Danish pirates.
In November of the same year, Edmund II, who was seriously wounded in the war, died, and Knut became the only king of Britain.
Knut has just consolidated his rule in England. In 1018, King Harald of Denmark died suddenly. Knut returned to his country and became the king of Denmark and Britain.

The young Knut became the ruler of a huge empire, but he was not satisfied with it.
The blood of the ancestors advocating force beats in his body.
He built a small elite army. He called this army the "Royal Army". The "Royal Forest Army" is composed of rich children and young aristocratic descendants. They always followed around the Emperor Knut, eating and living in the palace. They have strict discipline. Like the pirates in Yomsburg, they live a very strict life, have strict discipline, have strong fighting ability, and are loyal to King Knut. This army plays an important role in maintaining Knut's empire.
While Knut's reputation was at its zenith, the rule of King Olaf II of Norway was in crisis, and Norwegians were extremely dissatisfied with it.
In 1028, with the support of Norwegian nobles, Knut took the opportunity to enter Norway and defeated Olaf. Olaf fled abroad, and Knut became the king of Norway and ruled southern Sweden. In 1030, Olaf II's counterattack was defeated and Olaf was killed.
In this way, Knut established a great empire including Denmark, Norway, England, most of Scotland and southern Sweden. He was honored as the "Knut Great", and his empire was also known as the "North Sea Empire", which was the only emperor in history that almost unified the coastal areas of the North Sea.
In his great empire, Knut preferred England and lived in England for most of the year.
In England, he initially ruled as a conqueror, but later he gradually turned to the policy of appeasement and made large donations to the monasteries to win the trust and support of the local church.
He also worked hard to eliminate the differences between Danes and Englishmen. Since his grandfather, King Bluetooth, the Danish royal family has ruled as a Christian. Knut has sent priests to Denmark for preaching many times. During his reign, Christianity in Denmark developed rapidly.
When Knut lived in England, he made his brother-in-law Count Ulf the vice-king in Denmark.
Ulf attempted to seize power by taking advantage of the Danish people's dissatisfaction with Knut. After hearing the news, Emperor Knut quickly returned to Denmark and smashed the plot.
Ulf escaped into a church. He thought the church was a holy place, and Knut would not kill him. However, Knut's soldiers captured Ulf in the church and killed him in front of the altar.
Although Knut paid a large amount of fine to his sister and church, it can be seen that Knut's thought has the Christian confession side, and also has the aggressive side of Odin, which just reflects the complexity of the two religions in Denmark at this time.
Knut the Great had two queens:
She had two sons with the first queen, Elfgifu of Northampton:
Sweyn Knutson (1016-1035); Harold Harefoot.
With Emma of Normandy, the second queen, she had a son and a daughter:
Harthacnut (1018-1042, king of England, 1040-1042); Gunhilda of Denmark.
Knut was a ruler with means. He formulated the Knut Code and publicly punished himself for violating discipline.
There is a story that spreads widely. A subordinate of Knut flattered that Knut was the ruler of the sea, and even the sea would obey the orders of Knut the Great. Knut then ordered the chair to be placed on the seashore, and the sea water was not allowed to wet the feet of the chair. As a result, he reprimanded the minister's nonsense, saying that God was the ruler of the sea, and that the king's power was only a small amount.
Knut presided over the compilation of the Knut Code, which clearly stipulated the power of the king.
At the same time, in order to win the hearts of the people, Knut set up four Berks in Britain, of which the Wessex Berk was ruled by the Danish Godwin, and the four earls were all marquises of one side with great power, while Godwin, the Earl of Wessex, was the most powerful of the four Berks.
It should be noted that the United Kingdom has been unified at this time. Therefore, the Wessex Kingdom at this time was granted to ministers by the British king, which is quite different from the former independent Wessex Kingdom.

In 1035, Knut died, and his North Sea empire soon fell apart, becoming a flash in the pan in history.
His rule was the last glory of the Vikings. Since then, the pirate kingdom has never made any remarkable achievements.
The inclusion of Knut in the List of 100 Emperors Affecting the World is mainly due to the impact of his conquest and rule on the countries along the North Sea.
As an emperor who almost unified the North Sea, his rule greatly promoted the exchange of countries along the North Sea. One example is the acceleration of the spread of Christianity in the Nordic countries.
At present, many similarities can be found between the languages and cultures of England, Scotland, Denmark and Norway.
