State office in the early Turkic states, roughly equivalent to viceroy

Yabghu, also rendered as Jabgu, Djabgu or Yabgu, was a state office in the early Turkic states, roughly equivalent to viceroy. The title carried autonomy in different degrees, and its links with the central authority of Khagan varied from economical and political subordination to superficial political deference. The title had also been borne by Turkic princes in the upper Oxus region in post-Hephthalite times.
