North Sea Empire

1013–1042 empire in Northwest Europe

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.
