Bactria–Margiana Archaeological Complex

The extent of the BMAC (according to the Encyclopedia of Indo-European Culture)

Archaeological cultures associated with Indo-Iranian migrations (after EIEC). The Andronovo, BMAC and Yaz cultures have often been associated with Indo-Iranian migrations. The GGC (Swat), Cemetery H, Copper Hoard and PGW cultures are candidates for cultures associated with Indo-Aryan migrations.

The Bactria–Margiana Archaeological Complex (short BMAC), also known as the Oxus civilization, is the modern archaeological designation for a Bronze Age civilization of Central Asia, dated to c. 2400–1900 BC in its urban phase or Integration Era, located in present-day northern Afghanistan, eastern Turkmenistan, southern Uzbekistan and western Tajikistan, centred on the upper Amu Darya (Oxus River). Its sites were discovered and named by the Soviet archaeologist Viktor Sarianidi (1976). Bactria was the Greek name for the area of Bactra (modern Balkh), in what is now northern Afghanistan, and Margiana was the Greek name for the Persian satrapy of Marguš, the capital of which was Merv, in modern-day southeastern Turkmenistan.

Their DNA was mostly from Middle East Neolithic and did not contribute substantially to later populations.

Sarianidi's excavations from the late 1970s onward revealed numerous monumental structures in many sites, fortified by impressive walls and gates. Reports on the BMAC were mostly confined to Soviet journals until the last years of the Soviet Union, so the findings were largely unknown to the West until Sarianidi's work began to be translated in the 1990s.

Development

Early Food Producing Era

There is archaeological evidence of settlement in the well-watered northern foothills of the Kopet Dag during the Neolithic period, in this region, at Jeitun (or Djeitun), mud brick houses were first occupied during Early Food Producing Era, also known as Jeitun Neolithic from c. 7200 to 4600 BC. The inhabitants were farmers who kept herds of goats and sheep and grew wheat and barley, with origins in southwest Asia. Jeitun has given its name to the whole Neolithic period in the northern foothills of the Kopet Dag. At the late Neolithic site of Chagylly Depe, farmers increasingly grew the kinds of crops that are typically associated with irrigation in an arid environment, such as hexaploid bread wheat, which became predominant during the Chalcolithic period. This region is dotted with the multi-period hallmarks characteristic of the ancient Near East, similar to those southwest of the Kopet Dag in the Gorgan Plain in Iran.

Regionalization Era

Regionalization Era begins in Anau IA with a pre-Chalcolithic phase also in Kopet Dag piedmont region from 4600 to 4000 BC, then Chalcolithic period developes from 4000 to 2800 BC in Namazga I-III, Ilgynly Depe, and Altyn Depe. During this Copper Age, the population of the region grew. Archaeologist Vadim Mikhaĭlovich Masson, who led the South Turkmenistan Complex Archaeological Expedition from 1946, sees signs that people migrated to the region from central Iran at this time, bringing metallurgy and other innovations, but thinks that the newcomers soon blended with the Jeitun farmers. (Vadim was the son of archaeologist Mikhail Masson, who already started work in this same area previously.) By contrast a re-excavation of Monjukli Depe in 2010 found a distinct break in settlement history between the late neolithic and early chalcolithic eras there.

Major chalcolithic settlements sprang up at Kara-Depe and Namazga-Depe. In addition, there were smaller settlements at Anau, Dashlyji, and Yassy-depe. Settlements similar to the early level at Anau also appeared further east– in the ancient delta of the river Tedzen, the site of the Geoksiur Oasis. About 3500 BC, the cultural unity of the area split into two pottery styles: colourful in the west (Anau, Kara-Depe and Namazga-Depe) and more austere in the east at Altyn-Depe and the Geoksiur Oasis settlements. This may reflect the formation of two tribal groups. It seems that around 3000 BC, people from Geoksiur migrated into the Murghab delta (where small, scattered settlements appeared) and reached further east into the Zerafshan Valley in Transoxiana. In both areas pottery typical of Geoksiur was in use. In Transoxiana they settled at Sarazm near Pendjikent. To the south the foundation layers of Shahr-i Shōkhta on the bank of the Helmand river in south-eastern Iran contained pottery of the Altyn-Depe and Geoksiur type. Thus the farmers of Iran, Turkmenistan and Afghanistan were connected by a scattering of farming settlements.

Late Regionalization Era

In the Early Bronze Age, at the end of Late Regionalization Era (2800 to 2400 BC), the culture of the Kopet Dag oases and Altyn-Depe developed a proto-urban society. This corresponds to level IV at Namazga-Depe. Altyn-Depe was a major centre even then. Pottery was wheel-turned. Grapes were grown.

Integration Era

The height of this urban development was reached in the Middle Bronze Age also known as Integration Era, corresponding to Namazga-Depe level V (c. 2400-2000 BC). It is this Bronze Age culture which has been given the BMAC name. Gonur Depeis the largest of all settlements in this period and is located at the delta of Murghab river in southern Turkmenistan (Margiana region) with an area of around 55 hectares. An almost elliptical fortified complex, known as Gonur North includes the so called "Monumental Palace", other minor buildings, temples and ritual places, together with the "Royal Necropolis", and water reservoirs, all dating from around 2400 to 1900 BC.

Agriculture & economy

The inhabitants of the BMAC were sedentary people who practised irrigation farming of wheat and barley. With their impressive material culture including monumental architecture, bronze tools, ceramics, and jewellery of semiprecious stones, the complex exhibits many of the hallmarks of civilisation. The complex can be compared to proto-urban settlements in the Helmand basin at Mundigak in western Afghanistan and Shahr-e Sukhteh in eastern Iran, or at Harappa and Mohenjo-daro in the Indus Valley.

Models of two-wheeled carts from c. 3000 BC found at Altyn-Depe are the earliest complete evidence of wheeled transport in Central Asia, though model wheels have come from contexts possibly somewhat earlier. Judging by the type of harness, carts were initially pulled by oxen, or a bull. However camels were domesticated within the BMAC. A model of a cart drawn by a camel of c. 2200 BC was found at Altyn-Depe.

Art

Fertility goddesses, named "Bactrian princesses", made from limestone, chlorite and clay reflect agrarian Bronze Age society, while the extensive corpus of metal objects point to a sophisticated tradition of metalworking. Wearing large stylised dresses, as well as headdresses that merge with the hair, "Bactrian princesses" embody the ranking goddess, character of the central Asian mythology that plays a regulatory role, pacifying the untamed forces.

Architecture

Sarianidi regards Gonur as the "capital" of the complex in Margiana throughout the Bronze Age. The palace of north Gonur measures 150 metres by 140 metres, the temple at Togolok 140 metres by 100 metres, the fort at Kelleli 3 125 metres by 125 metres, and the house of a local ruler at Adji Kui 25 metres by 25 metres. Each of these formidable structures has been extensively excavated. While they all have impressive fortification walls, gates, and buttresses, it is not always clear why one structure is identified as a temple and another as a palace. Mallory points out that the BMAC fortified settlements such as Gonur and Togolok resemble the qila, the type of fort known in this region in the historical period. They may be circular or rectangular and have up to three encircling walls. Within the forts are residential quarters, workshops and temples.

The people of the BMAC culture were very proficient at working in a variety of metals including bronze, copper, silver, and gold. This is attested through the many metal artefacts found throughout the sites.

Extensive irrigation systems have been discovered at the Geoksiur Oasis.

Writing

The discovery of a single tiny stone seal (known as the "Anau seal") with geometric markings from the BMAC site at Anau in Turkmenistan in 2000 led some to claim that the Bactria-Margiana complex had also developed writing, and thus may indeed be considered a literate civilisation. It bears five markings which are similar to Chinese "small seal" characters. The only match to the Anau seal is a small jet seal of almost identical shape from Niyä (near modern Minfeng) along the southern Silk Road in Xinjiang, originally thought to be from the Western Han dynasty but now thought to date to 700 BC.

Interactions with other cultures

BMAC materials have been found in the Indus Valley Civilisation, on the Iranian Plateau, and in the Persian Gulf. Finds within BMAC sites provide further evidence of trade and cultural contacts. They include an Elamite-type cylinder seal and a Harappan seal stamped with an elephant and Indus script found at Gonur-depe. The relationship between Altyn-Depe and the Indus Valley seems to have been particularly strong. Among the finds there were two Harappan seals and ivory objects. The Harappan settlement of Shortugai in Northern Afghanistan on the banks of the Amu Darya probably served as a trading station.

There is evidence of sustained contact between the BMAC and the Eurasian steppes to the north, intensifying c. 2000 BC. In the delta of the Amu Darya where it reaches the Aral Sea, its waters were channelled for irrigation agriculture by people whose remains resemble those of the nomads of the Andronovo culture. This is interpreted as nomads settling down to agriculture, after contact with the BMAC, known as the Tazabagyab culture. About 1800 BC, the walled BMAC centres decreased sharply in size. Each oasis developed its own types of pottery and other objects. Also pottery of the Tazabagyab-Andronovo culture to the north appeared widely in the Bactrian and Margian countryside. Many BMAC strongholds continued to be occupied and Tazabagyab-Andronovo coarse incised pottery occurs within them (along with the previous BMAC pottery) as well as in pastoral camps outside the mudbrick walls. In the highlands above the Bactrian oases in Tajikistan, kurgan cemeteries of the Vaksh and Bishkent type appeared with pottery that mixed elements of the late BMAC and Tazabagyab-Andronovo traditions. In southern Bactrian sites like Sappali Tepe too, increasing links with the Andronovo culture are seen. During the period 1700 - 1500 BCE, metal artifacts from Sappali Tepe derive from the Tazabagyab-Andronovo culture.

Relationship with Indo-Iranians

See also: Indo-Aryan migration theory

The Bactria-Margiana complex has attracted attention as a candidate for those looking for the material counterparts to the Indo-Iranians (Aryans), a major linguistic branch that split off from the Proto-Indo-Europeans. Sarianidi himself advocates identifying the complex as Indo-Iranian, describing it as the result of a migration from southwestern Iran. Bactria–Margiana material has been found at Susa, Shahdad, and Tepe Yahya in Iran, but Lamberg-Karlovsky does not see this as evidence that the complex originated in southeastern Iran. "The limited materials of this complex are intrusive in each of the sites on the Iranian Plateau as they are in sites of the Arabian peninsula."

A significant section of the archaeologists are more inclined to see the culture as begun by farmers in the Near Eastern Neolithic tradition, but infiltrated by Indo-Iranian speakers from the Andronovo culture in its late phase, creating a hybrid. In this perspective, Proto-Indo-Aryan developed within the composite culture before moving south into the Indian subcontinent. As James P. Mallory phrased it:

It has become increasingly clear that if one wishes to argue for Indo-Iranian migrations from the steppe lands south into the historical seats of the Iranians and Indo-Aryans that these steppe cultures were transformed as they passed through a membrane of Central Asian urbanism. The fact that typical steppe wares are found on BMAC sites and that intrusive BMAC material is subsequently found further to the south in Iran, Afghanistan, Nepal, India and Pakistan, may suggest then the subsequent movement of Indo-Iranian-speakers after they had adopted the culture of the BMAC.

According to recent studies BMAC was not a primary contributor to later South-Asian genetics.

Evidence for a BMAC substratum in Indo-Iranian?

As argued by Michael Witzel and Alexander Lubotsky, there is a proposed substratum in Proto-Indo-Iranian which can be plausibly identified with the original language of the BMAC. Moreover, Lubotsky points out a larger number of words apparently borrowed from the same language, which are only attested in Indo-Aryan and therefore evidence of a substratum in Vedic Sanskrit. He explains this by proposing that Indo-Aryan speakers probably formed the vanguard of the movement into south-central Asia and many of the BMAC loanwords which entered Iranian may have been mediated through Indo-Aryan. Michael Witzel points out that the borrowed vocabulary includes words from agriculture, village and town life, flora and fauna, ritual and religion, so providing evidence for the acculturation of Indo-Iranian speakers into the world of urban civilisation.

Genetics
