Eleventh Century Danish King of England (6)

I believe the answer is:

canute

(Other definitions for canute that I've seen before include "Ancient king who ordered the waves to retreat" , "Old king of England who tried to stop the tide" , "The king who thought he could hold back the tide" , "King defeated by tide" , "Pre-Norman king of England & Denmark" .)

I've seen this clue in the Sydney Morning Herald.
