Article devoted to analysis the role and significance of Tatar-born Russian officials in gathering information about state and law of the Central Asian khanates – Bukhara, Khiva, Khoqand in the 18th-19th cc. on the examples of M.Bekchurin, M.Aitov and I.Batyrshin. All of them served as officials of the Orenburg Frontier Commission, two of them were diplomats in Bukhara and Khiva, last one contacted with informers from abovementioned khanates. The common feature for them was that they were Turks and Moslems. Firstly that fact provided Central Asian population’s sympathies to them (including favor of representatives of the ruling elites of the khanates) and gave an opportunity to gather more useful information. Secondly, as representatives of the Turkic-Islamic culture they could better understand and estimate the level of political and legal development of the Central Asian khanates and prepare impartial reports for their chiefs. Also it’s necessary to notice that their affiliation with Turkic-Islamic world didn’t influence on quality of fulfillment of missions by such officials: they tried all ways to contribute to realization of the Russian policy in the Central Asia and advance of the Russian Empire in this region.
