Bjørn

Who is Bjørn?

Bjørn was a Viking chieftain. He is the earliest known Scandinavian who was not a relative of the Danish kings to enter the service of a Frankish king, in his case Charles the Bald, king of West Francia. He is sometimes tenuously identified with the Swedish king Björn Ironside.

In July 856 a Viking chieftain named Sidroc entered the River Seine to pillage. On 19 August he was joined by a fleet commanded by Bjørn. Come winter Sidroc left Frankish waters while Bjørn built a fortified camp on an island called Oscellus, probably Oissel. The Vikings proceeded to raid as far as Bayeux and Évreux, and the entire region showed little resistance to their movements throughout 857.

The surviving sources do not record Bjørn's reasons for visiting King Charles at Verberie early in 858. In the words of the Annales Bertiniani, the preeminent West Frankish annals for the period: “Bjørn, leader of the faction of pirates of the Seine, pursuing King Charles came to the palace in Veberie, and giving him his hands, swore fidelity to him.” Bjørn had probably been offered tribute in return for submitting to the act of commendation. In November the bishops of West Francia, meeting in a synod at Quercy, sent a letter, probably authored by Hincmar, to Louis the German, the king of East Francia, in which the raising of tribute to pay off the Vikings is mentioned. Probably this refers to Bjørn and his men, since no other Vikings are known to have made their peace with the Franks at about this time.
