Harald III Hen of Denmark

Harald III, called Hen (c. 1040–1080), an illegitimate son of Sweyn II Estridsson, was king of Denmark from 1076. He joined his father's 1069 English raid and was elected king after promising to uphold the law.

A peaceful ruler, he standardized Danish coinage with royal mints and sought to reform trial by combat and hot-iron ordeals by introducing sworn oath-helpers after English custom. He died on 17 April 1080 and was buried at Dalby in Scania, leaving no heirs; Canute IV succeeded him.
