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 Kingdom of England was a sovereign state on the island of Great Britain from the early 10th century, when it emerged from various Anglo-Saxon kingdoms, until 1 May 1707, when it united with Scotland to form the Kingdom of Great Britain, which would later become the United Kingdom. The Kingdom of England was among the most powerful states in Europe during the medieval and early modern colonial periods.
