Harold Bluetooth (died about 985), king of Denmark (940?-985), who consolidated the Danish realm as a unitary kingdom. He was the son of Gorm the Old (d. about 940) and inherited his kingdom, centered on Jelling in Jutland. Although he temporarily (974-983) lost southern Jutland to Holy Roman Emperor Otto II, Harold secured all Denmark under his control and extended his rule to much of Norway. Baptized in 960 and thus introducing Christianity into Denmark, he had the famous Jelling rune stone erected in his parents' memory. Harold was fatally wounded during a rebellion by his son and successor, Sweyn I.
King Harald Bluetooth lived in Denmark between 910-940 AD, and was the son of Gorm.
Contrary to popular opinion, Bluetooth or "Blåtand" as it was in old Viking language had nothing to do with a blue tooth.
It means dark complexion - he had very dark hair, which was unusual for Vikings. Not only did Harald not fit the classic image physically, he was a rather unusual Viking.
That is, if your understanding was that the life of a Viking was all battles and pillage. The good King Harald brought Christianity to Scandinavia and also "united" Denmark and Norway. And while we are destroying long-held beliefs, Vikings did not have horns on their helmets!
Much of Harald's history was learnt from two runic stones erected to his memory in the town of Jelling in Denmark
