the göktürk rulers originated from the ashina clan, who were first attested to 439. the book of sui reports that in that year, on october 18, the tuoba ruler emperor taiwu of northern wei overthrew juqu mujian of the northern liang in eastern gansu, whence 500 ashina families fled northwest to the rouran khaganate in the vicinity of gaochang. peter benjamin golden points out the possibility that the khaghans of the turkic khaganate, the ashina, were themselves originally indo-europeans (possibly iranian peoples) who later adopted the turkic language but continued to use titles from their earlier indo-european languages. german turkologist w.-e. scharlipp points out that many common terms in turkic are iranian in origin.
