Cnut and the North Sea Empire

Who was King Cnut?
King Cnut was a Viking who ruled England from 1016 until 1035. He married Emma of Normandy, the widow of the previous Saxon king. As well as being king of England, he became king of Denmark and Norway, creating a North Sea Empire.
When was Cnut king of England?
There are some key dates in the reign of King Cnut:
  • Cnut originally came to England with his father, Sweyn Forkbeard, who defeated the English king Aethelred the Unready in 1013.
  • Sweyn's invasion might have been prompted by the St Brice's Day Massacre of 1002, when Aethelred the Unready ordered the murder of all Danes living in England.
  • However, Sweyn Forkbeard only lived for a short while after defeating Aethelred, dying in 1014. Aethelred resumed the English throne.
  • Cnut succeeded Sweyn as king of Denmark, and now had a 'right' to the English throne, too. So he invaded England again in 1016.
  • He fought against Aethelred's son, Edmund Ironside. Neither could claim outright victory, so eventually they agreed to divide England between them.
  • However, Edmund Ironside died only a couple of months later, and Cnut now became the king of all England.
  • In 1018 Cnut became king of Denmark, and in 1028 he became king of Norway. He now presided over a North Sea Empire, based around Scandinavia.

  • Because the Vikings had ruled large parts of England in the 9th century, Cnut believed he had a right to take the throne.
