'Horik I' (d. 854) reigned as sole
King of
Denmark from 827 to his violent death in 854. His reign was marked by Danish raids on the Franco-German empire of
Louis the Pious, son and successor of
Charlemagne.
Horik's father was King
Gudfred, known for his successful raids and wars against the Charlemagne's Frankish empire and against the
Abodrites. In 810, Godfred was assassinated by one of his retinue, and his nephew and successor
Hemming made peace with Charlemagne.
Hemming did not last long. Horik and another of Gudfred's sons took power in 811, later expelling a rival named
Harald, who took refuge at the court of Charlemagne's son and successor,
Louis the Pious. In 819, Louis forced Godfred's sons to accept Harald as co-ruler. Harald converted to
Christianity in 826, with Louis standing as his godfather, but Harald was driven out of Denmark for the second and final time in 827. By now just one of Godfred's sons -- Horik -- still lived. So in 827, Horik became sole king of the
Danes.
Horik refused to convert to Christianity, as it was his enemies' religion, and resisted attempts by Archbishop
Anskar of
Hamburg-
Bremen to proselytize the Danes. In 845, Horik's army attacked Hamburg and destroyed the cathedral there. It was Horik's last major war in
Germany.
However, Danish raids against
Frisia continued. The
Franks lacked an effective fleet, so the Danes could raid more or less with impunity. The Danes sacked the silver minting center of
Dorestad in 834, 835, and 836, and plundered
Walcheren in 837. In 845, a Viking warlord named Ragnar attacked
Paris and had to be bought off with 7000 pounds of gold and silver.
King Horik seems to have disapproved of these raids, for successful raiders constituted possible rivals. Occasionally, Horik even punished raiders. In 836, Horik sent an embassy to King Louis declaring that he had nothing to do with the raids on Frisia, and that he had executed those responsible. In 845, following Ragnar's mysterious death, he had Ragnar's followers massacred.
Events proved Horik's precautions to be fully justified. In 854, King Horik I was killed by a nephew whom he had driven into exile. While in exile, the nephew had become a successful raider.
