Uar and Hunnoi
The Kidarite dynasty which ruled the Xionites came from the Uar. As a result, the Xionites have sometimes been called Uar-Hunnoi.
Uar and Hunnoi are the names associated with the two biggest tribes of Procopius's White Huns, commonly identified with the Sanskrit Sveta Huna but called Varkhon or Varkunites (OuarKhonitai) by Menander Protector. Procopius writes that these White Huns are white-skinned and have an organized kingship. According to him, their life is not wild or nomadic, and they live in cities.
The Uar and Hunnoi are supposed to have united around 460 under the rule of one of the five Yuezhi families, the Hephthal. Near the end of the 6th century they were joined by the Zabender, Tarnach and Kutrigurs. They became known as the Onogurs, from whom the name Hungary derives. The Onogurs were composed of three groups, see also Avars and Kabars. Around 670 the Bulgars under Kouber and Asparukh, who were also part of their empire, revolted. The Kouber tribes moved south to Thessaly and Asparukh lead his people south of the Danube.
