The transition between the Final Bronze and Early Iron Age remains one of the least understood periods in the archaeology of southern Central Asia. In this paper, we introduce the newly discovered site of Kimirek-kum-1 (floruit ca. 1250-1050 CAL B.C.) in the old delta of the Zerafshan River in present-day Uzbekistan. Combined pedestrian survey, geomagnetic prospection, hand augering, and stratigraphic excavation, conducted between 2021 and 2023, demonstrate the site's unique potential to improve our understanding of the Final Bronze/Early Iron Age transition and the interface between the Central Eurasian steppes to the north and the Indo-Iranian world to the south. Notably, our investigations yielded nearly 400 objects in copper alloys, lead, gold, and semiprecious stone. These findings strongly suggest that Kimirek-kum-1 represents a substantial new Final Bronze/Early Iron Age center with extensive external links. It raises critical questions about the continuity of long-distance exchanges and elite networks after the end of the Oxus civilization.

Glass manufacturing processes and recipes changed fundamentally after the 8th century CE. The earlier centralised production system diversified, primary production sites multiplied, and the scale of individual productions contracted. Mineral soda was no longer used and instead replaced by plant ash as the main fluxing agent, affecting the chemical composition and properties of the glass. In this work, LA-ICP-MS and Raman spectroscopy were used to investigate the compositional and structural characteristics of 68 glass fragments recovered during recent excavations at Bukhara in Uzbekistan, dating to the 9th to early 11th centuries CE. This is the most extensive systematically collected and studied glass assemblage from Central Asia to date. The glass can be attributed to different origins, confirming on the one hand the diversification of glass production during the early Islamic period and, on the other hand, regional variations in the chemical compositions and network structure of soda-rich plant ash glasses. As clear archaeological evidence for early Islamic glass production sites in Central Asia is rare, regional production groups are distinguished primarily on relative concentrations of Mg, K, P, Cl, Li and Cs in relation to the plant ash component, while variabilities in Al, Ti, Cr, Y, Zr, Th and REEs and their ratios indicate different silica sources. Raman spectra suggest variations in network connectivity and Q n speciation that confirm compositional groupings and suggest structural differences between regional productions of plant ash glass. The results demonstrate a clear dominance of local or regional glass groups, while revealing the importation of Mesopotamian glass, notably a high-end colourless glass type from the region around Samarra in Iraq. The new analytical data allow further separation and characterisation of novel early Islamic plant-ash glass types and their production areas.

The Silk Road is a modern name for a globalization phenomenon that marked an extensive network of communication and exchange in the ancient world; by the turn of the second millennium AD, commercial trade linked Asia and supported the development of a string of large urban centers across Central Asia. One of the main arteries of the medieval trade routes followed the middle and lower Zarafshan River and was connected by mercantile cities, such as Samarkand and Bukhara. Bukhara developed into a flourishing urban center between the fourth and sixth centuries AD, served as the capital of the Samanid court between AD 893 and 999, and remained prosperous into the Qarakhanid period (AD 999-1220), until the Mongol invasion in AD 1220. We present the first archaeobotanical study from this ancient center of education, craft production, artistic development, and commerce. Radiocarbon dates and an archaeological chronology that has been developed for the site show that our samples cover a range between the third and eleventh centuries AD. These samples from Bukhara represent the richest systematically collected archaeobotanical assemblage thus far recovered in Central Asia. The assemblage includes spices and both annual and perennial crops, which allowed Sogdians and Samanids to feed large cities in river oases surrounded by desert and arid steppe and supported a far-reaching commercial market in the first millennium AD.

Rice is one of the most culturally valued and widely grown crops in the world today, and extensive research over the past decade has clarified much of the narrative of its domestication and early spread across East and South Asia. However, the timing and routes of its dispersal into West Asia and Europe, through which rice eventually became an important ingredient in global cuisines, has remained less clear. In this article, we discuss the piecemeal, but growing, archaeobotanical data for rice in West Asia. We also integrate written sources, linguistic data, and ethnohistoric analogies, in order to better understand the adoption of rice outside its regions of origin. The human-mediated westward spread of rice proceeded gradually, while its social standing and culinary uses repeatedly changing over time and place. Rice was present in West Asia and Europe by the tail end of the first millennium BC, but did not become a significant crop in West Asia until the past few centuries. Complementary historical, linguistic, and archaeobotanical data illustrate two separate and roughly contemporaneous routes of westward dispersal, one along the South Asian coast and the other through Silk Road trade. By better understanding the adoption of this water-demanding crop in the arid regions of West Asia, we explore an important chapter in human adaptation and agricultural decision making.

The pistachio (Pistacia vera L.) is commercially cultivated in semi-arid regions around the globe. Archaeobotanical, genetic, and linguistic data suggest that the pistachio was brought under cultivation somewhere within its wild range, spanning southern Central Asia, northern Iran, and northern Afghanistan. Historically, pistachio cultivation has primarily relied on grafting, suggesting that, as with many Eurasian tree crops, domestication resulted from genetically locking hybrids or favored individuals in place. Plant domestication and dispersal research has largely focused on weedy, highly adaptable, self-compatible annuals; in this discussion, we present a case study that involves a dioecious long-lived perennial-a domestication process that would have required a completely different traditional ecological knowledge system than that utilized for grain cultivation. We argue that the pistachio was brought under cultivation in southern Central Asia, spreading westward by at least 2000 years ago (maybe a few centuries earlier to the mountains of modern Syria) and moved eastward only at the end of the first millennium AD. The seeds remain rare in archaeological sites outside its native range, even into the mid-second millennium AD, and may not have been widely cultivated until the past few hundred years.

The article covers the results of new excavations at the citadel of Paikend, an ancient city in the south of Bukhara oasis (modern Uzbekistan).  The data obtained demonstrated that an extensive construction work was performed in the 2nd half of the 3rd – 4th cc. A.D. New protective walls, garrison’s barracks were built and the Fire temple was rebuilt. The details of the temple’s layout find parallels in Iranian cult architecture. The mural paintings were found as well. It is possible that they were influenced by Sasanian art. Coins, pottery, small products had also undergone changes and are similar to the Kushano-Sasanian material assemblage of Bactria-Tokharistan. The hypothesis proposed that the phenomenon related with the expansion of Sasanian Iran into the Bukhara oasis.

Until relatively recently, the centuries between Xiongnu and Türk domination in the Mongolian steppelands (both north and south of the Gobi Desert) appeared as an archaeological »dark age«. At the same time, the steppe empire of the Rouran has, compared to the polities of the Xiongnu and the Türks, received relatively little attention by modern historians.
In recent years however, archaeological discoveries have started to throw new light on this period, shattering long-held assumptions and, at the same time, generating new questions. Among the most important of these recent discoveries are five 5th century elite tombs found at Yihe-nur in southeastern Inner Mongolia.
Previous studies dealing with these sumpotously furnished tombs have been focused on detailing connections with the contemporary Northern Wei court culture, labeling the tomb owners either as »Xianbei« or as »Gaoche«. However, a closer look at a set of two exquisite parade belts and a peculiar type of pectoral found at Yihe-nur, suggests that the tomb owners of Yihe-nur also adhered to fashions that were much more
common in the steppes and in the »Western Regions« than in the Chinese heartland, pointing to elite networks spanning far across Central Eurasia. Finally, this paper will inquire into the question how a better understanding of the Rouran polity and its elites can shed additional light on these elite networks in the northern Chinese frontier and beyond during the 5th and early 6th century.

The present article argues that the earliest attestation of the city of Paykand in Bukhārān Soghd is to be found in the memoirs of the ‘Western regions’ of the Beishi and the extant Weishu (both going back to the now lost original ‘Xiyu zhuan’ of the Weishu). This identification has so far been overlooked due to a scribal error. This earliest mentioning of Paykand goes in all likelihood back to information gathered by the Northern Wei embassy of the years 436-437, which visited the various countries of the ‘Western regions’ up to Chāch.
Although the passage in question is relatively short, it nonetheless provides us with important details regarding the urbanization process in Paykand, the mercantile atmosphere already at this early stage of the development of the city, and the earliest attestation of rice in Sogdiana. It is quite possible that these details were provided to the Chinese emissaries by an informant from Bukhārān Sogd.

Excavations at the site of Bashtepa, at the western interface of the Bukhara oasis and the Kyzyl-kum desert, and at the kurgan sites at Kuyu-Mazar and Lyavandak on the eastern and north eastern fringes of the oasis, are detailed here, enriching our understanding of agro-pastoralism in Antiquity. At Bashtepa, results indicate a shifting site function, from a border fortress, over a phase during which a monumental though still poorly understood platform dominated the northern part of the site, to a final phase when the site evolved into a small rural settlement characterized by pit houses. Preliminary archaeo-botanical and paleo-zoological studies demonstrate an engagement with grain farming, but also with animal husbandry, as well as hunting and fishing. Ceramics indicate contacts with the surrounding oases. Excavations at the kurgans provide new data on burial architecture and funerary customs, including a collective burial with khums being used as containers for human bones. Results challenge the chronology of previously excavated comparable kurgans in the area, suggesting an earlier date. The analysis of ceramics from the kurgan burials underlines the need to rework the dating of the ceramic typology for the Bukhara oasis, especially for the period between the 3rd century BCE and the 3rd century CE.

The present article aims at publishing fourteen new terracotta figurines from Western (Bukharan) Sogdiana with their archaeological context. They were found between 2016 and 2018 during excavations and surface surveys at the sites of Bashtepa and Tali-Surkh. The specimens from Bashtepa were found in contexts dating between the middle of the 2nd century BCE and the late 1st century CE, the specimens from Tali-Surkh are surface finds. Also discussed are aspects regarding the interpretation and the production of terracotta figurines in post-Hellenistic Sogdiana and Bactria.

The study of urbanism in the oases of pre-Islamic south-western Central Asia remains a critical issue. However, modern perspectives are typically shaped by the iconic image of cities as densely populated commercial centres of intensively farmed oasis hinterlands, characteristic for the region during the pre-Islamic and Islamic Middle Ages. Yet for Sogdiana during antiquity, such a picture is problematic. At least for Bukharan Sogdiana – the focus of this study – there is no evidence for genuine urban centres before the 4th or 5th century CE. It is not easy to address questions concerning the character of settlements in the Bukhara oasis during antiquity. Certainly, part of the issue lies in the fact that Antique-period levels have not been extensively excavated inside the oasis, mostly due to the presence of massive later medieval occupation levels. Only at the fringes of the oasis – in areas outside the present-day and the medieval irrigated oasis – can we hope to get a more systematic insight into the question of how settlements and their patterns in the region looked during antiquity. In this paper we focus on the Antique site of Bashtepa and its surrounds, lying at the interface of the Bukhara oasis and the Kyzyl-kum Desert, in order to explore an example of a Central Asian oasis without cities.

In summer 2016 the Uzbek-American Expedition in Bukhara (UzAmEB) conducted the first field season at Bashtepa. Bashtepa is the westernmost site within a cluster of about a dozen of small tepas along several now dry terminal branches of the delta system of the Zerafshan river in Western Sogdiana, outside the medieval perimeter of the oasis. Works focused on two areas: the fortifications, and the central part of the site.
Excavations of the fortifications revealed three major construction phases, adding up to a width of more than 10 m at the base of the fortifications. There is no evidence for towers or bastions. In the central part of the site we encountered a monumental masonry block into which was cut a series of pits of varying dimensions. The larger pits seem to represent pit-houses, while others seem to be economic pits. C14 data range between the end of the 5th century BCE and the very beginning of the 2nd century CE. The ceramic inventory from the site – including the first known imitation of a Megarian bowl in Sogdiana – features a few Yaz III examples, but has otherwise strong parallels with the complexes of Hellenistic and post-Hellenistic sites in Central and Southern Sogdiana, Choresmia, Bactria, and Margiana. Bearing in mind the early stage of our investigations, we suggest that the site was first established as a border fortress on one of the main routes between Sogdiana and Chorasmia, most likely during the very end of the 4th or the first half of the 3rd century, that is during the early Seleucid period. During its last occupation phase the summit of the site seems to feature a small agro-pastoral settlement, dating to the 1st century CE or – at the very latest – to the very beginning of the 2nd century CE. Although preliminary in character our results from 2016 shed new light on the Hellenistic and post-Hellenistic periods in western Sogdiana, which are – up to now – poorly investigated.
The appendix is devoted to the finds of Hellenistic coins in the Bukharan oasis: a drachm with the types of Alexander, coppers of Antiochus I and Antiochus II/Diodotus, silver coins of Diodotus, Euthydemus, Demetrius, Eukratides, and Heliocles as well as Takhmachtepa hoard containing tetradrachms of Diodotus, Euthydemus, and Agathocles. Although the sample of Hellenistic coins is still very small, its composition suggests that the history of the Bukharan oasis followed the same path as the rest of Sogdiana, which was controlled by Seleucids until the middle of the 3rd century and then passed for a short time to Bactrian Greeks, who lost it no later than at the very beginning of the reign of Euthydemus (ca. 230 BCE).

SUMMARY The present article analyses Chinese histories and encyclopaedias for data on diplomatic contacts between Tang China and a country named Bosi (Persia) postdating the death of Yazdegerd III in 651 AD. Combined with evidence from Iranian apocalyptic texts, numismatics, and artistic metal ware they seem to point to the existence of a veritable Sasanian court-in-exile somewhere in the southern Hindukush area, i.e. in the political environment of the courts in Zāwul or Kāwul, until at least the middle of the 8th century. RÉSUMÉ Le présent article analyse des données pertinentes issues de sources historiques et ency-clopédiques chinoises portant sur les contacts diplomatiques entre la Chine des Tang et un pays nommé Bosi (Perse) postérieurs à la mort de Yazdegerd III en 651 de n.è. Ces données combinées avec les témoignages des textes apocalyptiques iraniens, de la numis-matique et des arts visuels semblent indiquer l'existence d'une véritable cour sassanide en exil quelque part dans la région méridionale de l'Hindou-Kouch, c.-à-d. relevant du milieu politique des cours de Zāwul ou de Kāwul jusqu'à au moins la moitié du VIII e siècle.

The present article summarizes the first field season of new investigations at the Devor-i Kampirak in Bukharan Sogd in 2011. In the first part we give a detailed description of our topographic survey, documenting a total of 15 sectors of the Kampirak in the western, eastern and – possibly – the northern fringes of the oasis.

The second part deals with the results of our excavations: at Sector 1 and at Sector 12. The profile at Sector 1 only revealed a pakhsa monolith, perhaps a platform of some non-preserved superstructure. In Sector 12 we observed a peculiar building technique: a sand-gravel pile was at both sides stabilized by a very coarse wall consisting of mortar and little irregular pakhsa lumps. The space between these two walls was filled with loose gravel. Only for the upper parts of the wall mudbricks were used (46-49×30-33×9-10 cm). A similar building technique has been observed at the Devor-i Kundalang near Rabat-i Gaziyon in Samarkand Sogd. Excavations at Section 12 also revealed a semi-circular bastion. The erosion layers of the bastion and the wall contained a significant number of diagnostic ceramic fragments suggesting the late 4th and 5th century as the original date of construction of the Kampirak in the delta area of the Zerafshan oasis.

In the third part we discuss observations resulting from a new topographic plan of the site Shakhri-Vayron. It shows that the center of the site is formed by a quadratic structure with four round towers at each side. This resembles a type of castles known from Chach, Ustrushana, and Samarkand Sogd, dating to 4th-5th centuries. However, the central structure at Shakhri-Vayron (measuring ca. 65 x 65 m) is 2-3 times larger than these small castles. While there are good arguments to finally reject the equation of Shakhri-Vayron with Tawawis-Arqud (which must be identified with the major site of Khodja-Buston) it is noteworthy that the central structure at Shakhri-Vayron is comparable in size with the “citadel” at Kafir-kala, the rural residence of the Ikhshids of Samarkand. Could the central structure at Shahri-Vayron originally also have functioned as a rural residence of the lords of Tawawis-Arqud, before it was later turned into a fortress in the system of the Devor-i Kampirak?

The Türgesh – one of the 10 “tribes” of the On Oq federation of the Western Türk – succeeded the Western Ashinas-Türk as an imperial power in the Western Central Asian steppes. Although the Türgesh Empire was relatively short-lived – it thrived for only about 20 years under their energetic khagan Sulu – it played an important role in the concert of great powers during the first half of the 8th century, largely on a par with Tang China, the Umayyad Caliphate, Tibet, and the Eastern Türks. The Türgesh are particularly known for having posed a serious threat to Umayyad rule in Mawarannahr and Eastern Khorasan/Tokharestan, inflicting several major defeats on Muslim armies in the 720s and 730s C.E. After the death of Sulu the Türgesh Empire quickly disintegrated, giving way to the immigrating Qarluq as the new dominant power in the steppes north of the Tianshan.

Abstract

The Khaganate (or Qaghanate) of the Türk, centered in the Central Eurasian steppes, was one of the hegemonic powers in Eurasia during the second half of the 6th and the first part of the 7th centuries C.E., exerting suzerainty over large parts of the Eurasian continent. The constituent hallmark of the empire of the Türk was the principle of collective sovereignty, vesting legitimate rule over the Türkic realm in the Ashinas lineage. This tradition – like other ideological as well as structural key features of their polity – the Türk inherited from their various predecessors in the steppes, notably the Xiongnu and the Rouran. Türk rule had a long-lasting impact on imperial ideologies and structures of governance in Eurasia down to the time of the Mongol Empire. Like the pax Mongolica in the 13th century, the unification of territories under Türk rule, from Manchuria in the east to Crimea in the west, resulted in a considerable increase of trans-cultural economic and diplomatic exchanges across Eurasia.

Using Structure from Motion (SfM) software and low-cost UAVs equipped with digital camera systems, archaeologists record high-resolution image series of sites and produce orthoimages, elevation models and textured 3D models. In practice, however, one of the biggest challenges in image-based 3D reconstruction remains ensuring that the image series contains sufficient overlap and full coverage of the site. In this respect, video streams are an intriguing alternative (or complementary) source of image data. Although each individual video frame has a relatively low resolution, the enormous number of frames and the almost complete overlap between consecutive frames provide ideal input for SfM reconstruction algorithms. Another attractive aspect is the sheer speed at which distortion free HD video can be recorded by current consumer cameras.
Our primary aim is the development of truly rapid and robust 3D recording technologies. We constrain ourselves to freely available software and low-cost consumer hardware. In October 2014 we put our ambitions to the test by documenting 13 monumental medieval fortresses in the harsh climate of Uzbekistan. The results are encouraging not only because they show how much can be achieved with very limited resources and in adverse environmental conditions, but also that current SfM and surface reconstruction algorithms are capable of handling the low-contrast, sparsely structured remains of typical mud brick architecture.
This paper discusses a number of key aspects and techniques to consider on the way to establishing a best-practice routine for SfM-based reconstruction using UAV-mounted cameras and video streams (as well as mixed video and image-based reconstructions). We discuss aspects ranging from pre-flight planning (weather and light conditions, operational safety, legal restrictions, etc.) to hardware selection, modification and maintenance (always focused on low-cost and sturdy consumer hardware), flight control software (including mobile applications) and data processing. Regarding the latter, we consider both on-site data processing of sparse preview models and off-site processing of complete, fully textured models.
