The name Kutrigur, also recorded as Kwrtrgr, Κουτρίγουροι, Κουτούργουροι, Κοτρίγουροι, Κοτρίγοροι, Κουτρίγοροι, Κοτράγηροι, Κουτράγουροι, Κοτριαγήροι,[2] has been suggested as a metathecized form of Turkic *Toqur-Oğur, with *quturoğur meaning "nine Oğur (tribes)".
[12] This story was also confirmed by the words of the Utigur ruler Sandilch:It is neither fair nor decent to exterminate our tribesmen (the Kutrigurs), who not only speak a language, identical to ours, who are our neighbours and have the same dressing and manners of life, but who are also our relatives, even though subjected to other lords".
[10]Agathias Scholasticus, Greek poet and the principal historian of part of the reign of the Roman emperor Justinian I. recalls the origin of their name as follows:"In ancient times the Huns inhabited the region east of lake Maeotis to the north of the river Don, as did the rest of the barbarian peoples established in Asia on the near side of Mount Imaeus.
"[13]The Syriac translation of Pseudo-Zacharias Rhetor's Ecclesiastical History (c. 555) in Western Eurasia records thirteen tribes, the wngwr (Onogur), wgr (Oğur), sbr (Sabir), bwrgr (Burğar, i.e. Bulgars), kwrtrgr (Kutriğurs), br (probably Abar, i.e. Avars), ksr (Kasr; Akatziri?
[16]In 551, a 12,000-strong Kutrigur army led by many commanders, including Chinialon, came from the "western side of the Maeotic Lake" to assist the Gepids who were at the war with the Lombards.
[11] In the winter of 558, the remaining large Kutrigur army led by Zabergan crossed the frozen Danube and divided into three sections; one raided south as far as Thermopylae; while two others the Thracian Chersonesus; and the periphery of Constantinople.
[20] The transit of such distances in a short period of time shows that they were mounted warriors,[19] and compared to the Chinialon's army, Zabergan's raiders were already encamped near the banks of the Danube.
[22][7] Between 630 and 635, Khan Kubrat managed to unite the Onogur Bulgars with the tribes of the Kutrigurs and Utigurs under a single rule, creating a powerful confederation which was referred to by the medieval authors in Western Europe as Old Great Bulgaria,[23] or Patria Onoguria.
