Taking the English throne was the very beginning of a conquest that saw King Cnut rule most of Northern Europe, by the time of his death he controlled England, Denmark, Norway and parts of Sweden, yet the one event he is only ever remembered for is his attempt at controlling an incoming tide, Cnut probably didn’t paddle in the sea but what he is thought to have said was:
“Let all inhabiting the world know the power of kings to be empty and worthless and that there is no other king worthy
of the name but He at whose will heaven earth, sea obey by the eternal laws.”
Not the words of arrogant and powerful foreign invader, just man suggesting that a kings were human.
Cnut controlled much of Scandinavia, under his rule Viking raids on England’s coastline lessened, the economy improved, and by marrying Emma, Ethelred the Unready’s Norman widow, he consolidated his power.
