This substantial article offers an overview of some wide syntheses recently published by a leading Uzbekistani archaeologist and historian of the ancient and early mediaeval civilisations of Central Asia, notably through his monograph Tsivilizatsii, gosudarstva, kul’tury Tsentral’noi Azii (Tashkent, 2005). The author underlines Edvard Rtveladze’s lasting interest in the role of civilisations as the driving force behind the appearance of statehood, since the Bronze Age; he also stresses his insistence on the deepest impact of permanent migrations upon Central Asia’s ethnic history on the long duration. A special chapter on Rtveladze’s Istoriia i numizmatika Chacha, vtoraia polovina iii v. n.e. – seredina viii v. n.e. [The History and Numismatics of Chach [ancient Tashkent], from the Second Half of the Third to the Mid-Eighth Century, Tashkent, 2006] sheds a well-chosen light on the historian’s interest in the formation of early Turkic statehood in western Central Asia, the beginning of which could be dated by more than a century earlier than in pre-existing literature (allusions to Rtveladze’s study of the role of rulers like Tun-Yabgu, Tegin of Chach, and Kunigur-Tudun, as well as by the city of Chach itself in the emergence of this statehood, through a pioneering study of numismatic sources).
