Canute Henriksen
Canute Henriksen (c. 1110–1162) was a son of Prince Henrik Skadelår. During the civil war he fought for Canute V and helped drive Sweyn Grathe and Valdemar out of Schleswig. After Canute V was murdered at the Bloodfeast of Roskilde in 1157, he and his brother Buris switched sides, helping Valdemar win at Grathe Heath and become sole king.
Rewarded with the Duchy of Schleswig, Canute ruled it until his sudden death in 1162. He left no children and was succeeded by Buris.
