The Kylfings (Old Norse Kylfingar; Estonian Kalevid; Hungarian Kölpények; Old East Slavic Колбяги, Kolbiagi; Byzantine Greek Κουλπίγγοι, Koulpingoi; Arabic al-Kilabiyya) were a people of uncertain origin active in Northern Europe during the Viking Age, roughly from the late ninth century to the early twelfth century.
According to the sagas, the Kylfings opposed the consolidation of Norway under Harald Fairhair and participated in the pivotal late ninth century Battle of Hafrsfjord.
He hypothesised that Kylfingr was a direct Norse translation of the Votic self-designation Vatjalaiset and Vatja (or Vadjalaiset and Vadja) used by the Votes, a Finnic people residing in Ingria, Russia.
Thorolf Kveldulfsson, King Harald's tax agent in northern Norway, engaged Saami scouts to monitor the Kylfings' movements and report back to him.
[13] Some scholars see them as Scandinavians while others consider them to have been a Finnic tribe, and assert a connection between the word Kylfing and the Finnish, Saami, and Karelian myths of Kaleva.
[14] Elsewhere they are described as a mixture of Norse and Finnish people who were employed as mercenaries and tax-agents by Scandinavian rulers; in this context Ravndal interpreted the kylfa element to refer to a "club" in the sense of organization.
Carl Christian Rafn, Edgar V. Saks, B. Briem and Sigurður Nordal have proposed Kylfings to have been the Norse name for the Votes.
Holm considers it apparent that the Varangians and the Finnic tribes were able to cooperate well, and he points to the relative ease and stability with which Finland was later integrated as a part of the Swedish kingdom.
[21] Barði Guðmundsson identified the Kylfings as an East Scandinavian, possibly Swedish, tribe that infiltrated northern Norway during the late ninth century.
[5] Some scholars have considered the Kylfings of Egil's Saga to be a "conquering Germanic people", or the Swedish king's tax collectors.
Under this interpretation, the Slavic term Kolbiag may share common origins with such place-names as Kołobrzeg (formerly Kolberg), a town on the Pomeranian Baltic coast, and Kolpino, a settlement near modern St.
[29] Eleventh-century Byzantine sources refer to Kylfings (Κουλπίγγοι, Koulpingoi; often attested in the genitive plural Κουλπίγγων, Koulpingon) as being among the foreigners serving as mercenaries in Constantinople, but appear to distinguish between them and the Varangians.
[30][31] For instance, an imperial chrysobull, an edict bearing a golden seal, issued in 1073 exempts certain monasteries from being forced to billet soldiers of specific ethne: Varangians, Rus', Saracens, Franks and Koulpingoi.
[32] The edict issued by Alexios I Komnenos 1088, for instance, reads: The whole of the above-mentioned island [of Patmos], as well as the monastery with all its properties, is granted exkousseia [exemption] from the billetting [mitata] of all commanders, both Rhomaioi and foreign allies, that is the Rus, Varangians, Koulpingoi, Inglinoi, Frangoi, Nemitsoi, Bulgarians, Saracens, Alans, Abasgoi, the Immortals, and all other Romans and foreigners.
[5][34] The eleventh-century Ruskaya Pravda, the law code of the Kievan Rus', grants certain privileges to Kylfings (Колбяги or "Kolbiagi") in addition to Varangians ("Varyagi").
[40] Others, such as F. Jonsson, interpreted Austkylfur to mean "eastern logs", while Vigfusson believed that the phrase properly meant simply "men of the east".
As such they formed part of the force, led by Kjotve the Rich of Agder and the kings and jarls of Hordaland, Rogaland, and Telemark, that came to Hafrsfjord to fight Harald's encroaching hegemony.
[39] After their defeat by Harald and his army, the Kylfings' property was plundered and their womenfolk, described as "eastern maidens", were distributed by the victorious king among his warriors.
