Abstract
Nothing of the kind has been transmitted for Central Asia. On the other hand, Sogdiana provides data for these periods testifying to the rapid assimilation of successive waves of newcomers, particularly among the merchant class then expanding on the trade routes. In Sogdian inscriptions from the upper Indus, dating from around the5th century , "Khūn" accounts for a third of the names, including sixteen whose fathers bore Sogdian names. In the early 8thcentury , the ruler of Bukhara was still called Khūnak. The painting in the cella of the Dzhartepe temple (5th century , pre-Hephtalite?) probably shows the new mixed aristocracy hunting in the "paradise" of the rulers of Samarkand. Linguistically, for the pre-Hephtalite period we have a few rare onomastic clues indicating an Altaic language: Khunkhas = "khan of the Huns", "Huns Oghlar" *Oghullar, "princely Huns" or "Huns Oghur" (the Oghur would later become the other major division of the Turks along with the Oghuz).
For the Hephtalite period, textual data become even more numerous and diverse, but they leave us with very contrasting impressions. There are two ways of looking at these contrasts: a hybrid politico-social structure or a chronological evolution. A bit of both, no doubt.
