The pirate empire developed by the Danish king finally reached its peak in Knut's hands. He is the grandson of Harald Blatand and the second son of Swann bearded king. Swann's bearded king conquered most of England in 10 14, becoming the first Dane to be recognized as king by the English. Knut was the real overlord of northwest Europe at that time and the man of the hour in Norman Conquest. He made Denmark reach the peak and was called "Knut the Great" in history.
