Origins & Early Life

The North Sea Empire, also known as the Anglo-Scandinavian Empire, was the personal union of the kingdoms of England, Denmark and Norway for most of the period between 1013 and 1042 towards the end of the Viking Age. This ephemeral Norse-ruled empire was a thalassocracy, its components only connected by and dependent upon the sea. The first king to unite all three kingdoms was Sweyn Forkbeard, king of Denmark since 986 and of Norway since 1000, when he conquered England in 1013. He died in the following year, and his realm was divided. His son Cnut the Great acquired England in 1016, Denmark in 1018 and Norway in 1028.

Career & Major Achievements

He died in 1035 and his realm was again divided, but his successor in Denmark, Harthacnut, inherited England in 1040 and ruled it until his death in 1042. At the height of his power, when Cnut ruled all three kingdoms (1028–1035), he was the most powerful ruler in western Europe after the Holy Roman Emperor. The term "North Sea Empire" was coined by historians at the beginning of the 20th century, although the conception of Cnut's domains as having constituted an empire can be found as early as 1623, in John Speed's Histoire of Great Britaine. Historically, the union was referred to by its individual parts: the kingdoms of Denmark, Norway, and England. As a largely maritime empire, it is often considered a thalassocracy.

Enduring Legacy & Impact

Cnut was the younger son of the Danish king Sweyn Forkbeard. In early 1014 Sweyn and the Danes were in the midst of invading England. Cnut joined the expedition, and was given command of the fleet in the River Trent during one of Sweyn's visit to the south. Sweyn died on 3 February, and Cnut had the early support of his Danish troops. But the invasion fell apart as the men of the Kingdom of Lindsey failed to supply horses they had promised.
