Kura–Araxes culture

The Kura–Araxes culture (also named Kur–Araz culture, Mtkvari–Araxes culture, Early Transcaucasian culture) was an archaeological culture that existed from about 4000 BC until about 2000 BC, which has traditionally been regarded as the date of its end; in some locations it may have disappeared as early as 2600 or 2700 BC. The earliest evidence for this culture is found on the Ararat plain; it spread north in the Caucasus by 3000 BC.

Altogether, the early Transcaucasian culture enveloped a vast area approximately 1,000 km by 500 km, and mostly encompassed the modern-day territories of the South Caucasus (except western Georgia), northwestern Iran, the northeastern Caucasus, eastern Turkey, and as far as Syria.

The name of the culture is derived from the Kura and Araxes river valleys. Some local variations of the Kura–Araxes culture are sometimes known as Shengavitian, Karaz (Erzurum), Pulur (after a site renamed later as Sakyol), and Yanik Tepe (Iranian Azerbaijan, near Lake Urmia) cultures. It gave rise to the Khirbet Kerak-ware culture found in the Levant and Trialeti culture of the South Caucasus and Armenian Highlands. In Nakhchivan region and nearby areas, Kura-Araxes culture was followed by Nakhchivan culture.

Early history
The formative processes of the Kura-Araxes cultural complex, and the date and circumstances of its rise, have been long debated.

Shulaveri-Shomu culture preceded the Kura–Araxes culture in the area. There were many differences between these two cultures, so the connection was not clear. Later, it was suggested that the Sioni culture of eastern Georgia possibly represented a transition from the Shulaveri to the Kura-Arax cultural complex.

At many sites, the Sioni culture layers can be seen as intermediary between Shulaver-Shomu-Tepe layers and the Kura-Araxes layers. This kind of stratigraphy warrants a chronological place of the Sioni culture at around 4000 BCE.

Some scholars consider the Kartli and Kakheti areas as key to forming the earliest phase of the Kura–Araxes culture. To a large extent, this appears as an indigenous culture of Caucasus that was formed over a long period, and at the same time incorporating foreign influences.

There are some indications (such as at Arslantepe) of the overlapping in time of the Kura-Araxes and Uruk cultures; such contacts may go back even to the Middle Uruk period.

Some scholars have suggested that the earliest manifestation of the Kura-Araxes phenomenon should be dated at least to the last quarter of the 5th millennium BC. This is based on the recent data from Ovçular Tepesi, a Late Chalcolithic settlement located in Nakhchivan by the Arpaçay river.



Expansion
Rather quickly, elements of Kura–Araxes culture started to proceed westward to the Erzurum plain, southwest to Cilicia, and to the southeast into the area of Lake Van, and below the Urmia basin in Iran, such as to Godin Tepe. Finally, it proceeded into the present-day Syria (Amuq valley), and as far as Israel.

Its territory corresponds to large parts of modern Armenia, Azerbaijan, Chechnya, Dagestan, Georgia, Ingushetia, North Ossetia, and parts of Iran and Turkey.

At Sos Hoyuk, in Erzurum Province, Turkey, early forms of Kura-Araxes pottery were found in association with local ceramics as early as 3500-3300 BC. During the Early Bronze Age in 3000-2200 BC, this settlement was part of the Kura-Araxes phenomenon.

At Arslantepe, Turkey, around 3000 BCE, there was widespread burning and destruction, after which Kura-Araxes pottery appeared in the area.

According to Geoffrey Summers, the movement of Kura-Araxes peoples into Iran and the Van region, which he interprets as quite sudden, started shortly before 3000 BC, and may have been prompted by the 'Late Uruk Collapse' (end of the Uruk period), taking place at the end of Uruk IV phase c. 3100 BC.

Iranian sites
There are many important Kura-Araxes sites located along the Araxes river, south of which is modern Iran. Kultepe, Azerbaijan, in Nakhchivan Autonomous Republic close to Araxes river, has already been known for a long time. In Iran, the excavations especially accelerated in the 21st century. Kul Tepe Jolfa, a related site, is seen as an important gateway for Kura-Araxes culture on its way south towards Lake Urmia area. Ancient obsidian trade and distribution are particularly revealing of cultural connections, and Kul Tepe Jolfa was an important transshipment point for the movement of Caucasian obsidian to Iranian sites. This trade was probably conducted by groups of mobile pastoralists from Iran.

Also in Iran downstream the Araxes river, two additional sites from the same period have recently been excavated, Kohne Pasgah and Kohne Tepesi.

Many other Iranian sites have come to light recently and have been excavated already.

Cultural connections
Kura–Araxes culture is closely linked to the approximately contemporaneous Maykop culture of the North Caucasus. The two cultures seem to have influenced one another.

Economy
The economy was based on farming and livestock-raising (especially of cattle and sheep). They grew grain and orchard crops, and are known to have used implements to make flour. They raised cattle, sheep, goats, dogs, and in later phases, horses.

Before the Kura-Araxes period, horse bones were not found in Transcaucasia. Later, beginning about 3300 BCE, they became widespread, with signs of domestication.

There is evidence of trade with Mesopotamia as well as Asia Minor. It is, however, considered above all to be indigenous to the Caucasus, and its major variants characterized (according to Caucasus historian Amjad Jaimoukha) later major cultures in the region.

Settlements
Archaeological evidence of inhabitants of the Kura–Araxes culture showed that ancient settlements were found along the Hrazdan river, as shown by drawings at a mountainous area in a cave nearby. Structures in settlements have not revealed much differentiation, nor was there much difference in size or character between settlements, facts that suggest they probably had a poorly developed social hierarchy for a significant stretch of their history. Some, but not all, settlements were surrounded by stone walls. They built mud-brick houses, originally round, but later developing into subrectangular designs with structures of just one or two rooms, multiple rooms centered around an open space, or rectilinear designs.

At some point the culture's settlements and burial grounds expanded out of lowland river valleys and into highland areas. Although some scholars have suggested that this expansion demonstrates a switch from agriculture to pastoralism and that it serves as possible proof of a large-scale arrival of Indo-Europeans, facts such as that settlement in the lowlands remained more or less continuous suggest merely that the people of this culture were diversifying their economy to encompass crop and livestock agriculture.

Shengavit Settlement is a prominent Kura-Araxes site in present-day Yerevan area in Armenia. It was inhabited from approximately 3200 BC cal to 2500 BC cal. Later on, in the Middle Bronze Age, it was used irregularly until 2200 BC cal. The town occupied an area of six hectares, which is large for Kura-Araxes sites.

Metallurgy
In the earliest phase of the Kura–Araxes culture, metal was scarce. In comparison, the preceding Leilatepe culture's metalwork tradition was far more sophisticated. Especially after 3000 BC, a significant increase in the use of metal objects occurred at Kura-Araxes sites. Also the variation in copper alloys increased during this time. The rich tomb of a woman at Kvazchela is a good example of this, which is quite similar to the 'royal tomb' from Arslantepe. The use of an arsenical component up to 25% in copper objects resulted in a shiny greyish, silvery colour. So it's quite possible that these unusually high arsenical alloys were intended to imitate silver.

The Kura–Araxes culture would later display "a precocious metallurgical development, which strongly influenced surrounding regions". They worked copper, arsenic, silver, gold, tin, and bronze.

Their metal goods were widely distributed, from the Volga, Dnieper and Don-Donets river systems in the north to Syria and Palestine in the south and Anatolia in the west.

Pottery


Their pottery was distinctive. The spread of their pottery along trade routes into surrounding cultures was much more impressive than any of their achievements domestically. It was painted black and red, using geometric designs. Examples have been found as far south as Syria and Israel, and as far north as Dagestan and Chechnya. The spread of this pottery, along with archaeological evidence of invasions, suggests that the Kura-Araxes people may have spread outward from their original homes and, most certainly, had extensive trade contacts. Jaimoukha believes that its southern expanse is attributable primarily to Mitanni and the Hurrians.

According to Giulio Palumbi (2008), the typical red-black ware of Kura–Araxes culture originated in eastern Anatolia, and then moved on to the Caucasus area. But then these cultural influences came back to Anatolia mixed in with other cultural elements from the Caucasus.

Köhne Shahar is a very large Kura-Araxes archaeological site in Iran located close to the Turkish border. Situated in a narrow valley at the altitude of 1905m asl, it was excavated in 2012-2014. It was located on the trade route between Iran and Anatolia.

Viticulture
Viticulture and wine-making were widely practised in the area from the earliest times. Viticulture even goes back to the earlier Shulaveri-Shomu culture.

The earliest evidence of domesticated grapes in the world has been found at Gadachrili Gora, near the village of Imiri, Marneuli Municipality, in southeastern Republic of Georgia; carbon-dating points to the date of about 6000 BC.

Grape pips dating back to the V-IVth millennia BC were found in Shulaveri; others dating back to the IVth millennium BC were found in Khizanaant Gora—all in this same 'Shulaveri area' of the Republic of Georgia.

A theory has been suggested by Stephen Batiuk that the Kura-Araxes folk may have spread Vitis vinifera vine and wine technology to the "Fertile Crescent"—to Mesopotamia and the Eastern Mediterranean. The spread of the wine-goblet form, such as represented by the Khirbet Kerak ware, is clearly associated with these peoples. The same applies to the large ceramic vessels used for grape fermentation.

Burial customs
Inhumation practices are mixed. Flat graves are found but so are substantial kurgan burials, the latter of which may be surrounded by dolmen. This points to a heterogeneous ethno-linguistic population (see section below).

Analyzing the situation in the Kura-Araxes period, T. A. Akhundov notes the lack of unity in funerary monuments, which he considers more than strange in the framework of a single culture; for the funeral rites reflect the deep culture-forming foundations and are weakly influenced by external customs. There are non-kurgan and kurgan burials, burials in ground pits, in stone boxes and crypts, in the underlying ground strata and on top of them; using both the round and rectangular burials; there are also substantial differences in the typical corpse position. Burial complexes of Kura–Araxes culture sometimes also include cremation.

Here one can come to the conclusion that the Kura–Araxes culture developed gradually through a synthesis of several cultural traditions, including the ancient cultures of the Caucasus and nearby territories.

Late Kura-Araxes sites often featured Kurgans of greatly varying sizes, with larger, wealthier kurgans surrounded by smaller kurgans containing less wealth. These kurgans also contained a wide assortment metalworks. This trend suggests the eventual emergence of a marked social hierarchy. Their practice of storing relatively great wealth in burial kurgans was probably a cultural influence from the more ancient civilizations of the Fertile Crescent to the south.

In the 3rd millennium B.C., one particular group of mounds of the Kura–Araxes culture is remarkable for their wealth. This was the final stage of culture's development. These burial mounds are known as the Martqopi (or Martkopi) period mounds. Those on the left bank of the river Alazani are often 20–25 meters high and 200–300 meters in diameter. They contain especially rich artefacts, such as gold and silver jewelry.

Ethno-linguistic makeup
While it is unknown what languages were present in Kura-Araxes, the two most widespread theories suggest a connection with Hurro-Urartian   and/or Anatolian languages. The Kartvelian and Northeast Caucasian languages were likely spoken in the region as well. A 2023 study employing Bayesian linguistic phylogenetics in conjunction with archaeological, ethnoecological, and human population genetic data suggests that Proto-Karto-Zan (i.e. Proto-Georgian-Zan) prior to its split into Georgian and Zan was spoken by pre-Kura-Araxes and Kura-Araxes farmers that thrived in the watershed of Mtkvari (Kura) River during the Copper and Bronze Ages.
