Prehistory of the Steppes
The original people of the western and central steppes were likely
Proto-Uralic (the ancestors to Finnish, Hungarian, Samoyede, etc.).
They would include the neolithic Samara culture of the Volga valley,
as well as the fishing communities of the Kelteminar culture further
south. These would evolve into the Pit-Comb culture beginning around
4200 bc, which would extend all the way to Scandinavia and both
sides of the Ural mountains, including the Khvalynsk copper culture
of the Volga valley.
At around this same time period, proto-Indo-Europeans (PIE) were
expanding from the Balkans into the Ukraine. The Dnieper-Donets
culture (~5000 bc) and the Sredny Stog culture (~4000 bc)
represented an eastern PIE dialect, ancestral to the Indo-Iranian
and possibly the Tokharian and Hittite languages as well.
Note: Most linguists follow Marija Gimbates' Kurgan theory. A smaller group follow Colin Renfrew's Anatolian theory. I am admittedly only an amateur, but I prefer Diakonov's Balkan theory, which is also a part of Renfrew's extended theory
Botai culture (~3700 bc) was perhaps the first to domesticate the horse. It is highly uncertain whether they spoke an early Uralic dialect or represented a "far-eastern" PIE dialect, possibly the ancestor of Tokharian.
The Stedny Stog culture would continue
to evolve into the proto-Indo-Iranian dialect. These
proto-Indo-Iranians would over time move eastward and be at least partially responsible for the development of the
extensive Yamna culture (~3600). The Yamna culture would absorb much
of the earlier eastern PIE and proto-Uralic people, as well as drive
others even further east. It may have remained linguistically diverse for many centuries
Of the eastern PIE people, one group, already by this time located along the Kuba river valley north of
the Caucasus, developed the Maykop culture (~3700 bc), which thrived
as an intermediary between the Indo-Iranians of the steppes and the
civilizations south of the Caucasus. I believe that they would
eventually move into Anatolia to become the Hittites and their
relations. Another group moved north and east where, by 3300 bc,
they would form the Afanasevo culture of the Tokharians.
In the following millenium, we see several bronze age cultures
develop in the area: the Catacomb culture (~2800 bc) in the Ukraine;
the Poltavka culture (~2700 bc) in the Volga valley; and, north of
the Poltavka culture, the Abashevo culture (~2500 bc), which may
have been at least in part Finno-Ugric.
Next, we see the Sintashta culture (~2100 bc) - which introduced the chariot - and the broader Andronovo culture (~2000 bc) in what is now Kazakhstan.
After the Sintashta and Andronovo, we find the Srubna culture (~1800 bc) which ranged from Ukraine to the Ural mountains, with the Andronovo continuing to the east. This culture may have included the Cimmerians, who would be pushed back into eastern Europe by the Indo-Iranian Scyths and, eventually, invade Anatolia.
The famous Tarim Basin mummies (Xinjiang, in western China) -
presumed to be Tokharian - are from this time period as well, the
earliest dating to 1800 bc. By the final centuries bc, the Yuezhi -
likely Tokharians - would be displaced by the Turkish Xiongnu, the beginnings of the westward movement of Turkish tribes that would eventually lead them to Anatolia and domination of central Asia, while the Indo-Europeans of the steppes moved towards and into southern Asia.
The Bactrian-Margiana archeological complex, which thrived from 2300 to 1700 aec, was a culture of sedentary farmers living in fortified villages in the area between what is now Kazakhstan and Afghanistan. Their culture was related more to the cultures to the south than to the cultures of the steppes to their north, and they may have been of Dravidian stock.
It is possible that the Indo-Iranians raided the farmers of the area over centuries, eventually becoming a dominating group while adopting the farmers' culture (similar to the way that China succumbed to the "barbarians" from the steppes to the west).
From the Bactria-Margiana area, a portion of the Indo-Iranians would eventually (circa 1500 bc) enter the area that is now Syria as the Mittani, a ruling class among the Hurrians. Soon after, other Indo-Iranians would travel from Bactria through the mountain passes into the Swat Valley and beyond, where they would become the ruling class in most of northern India.
The Iranians of the steppes would, in the final millennium bc, expand in many directions: They would move back into eastern Europe as the Scyths and Sarmatians. They would move east to Xinjiang as the Sakas. And they would move into the Iranian plateau where they would become the Persians, Parthians, and Medes.
By the last centuries bc, the Scyths
and their relations would be driven out of the steppes or absorbed by the Turks,
resulting in a spit between the Asian Indo-Europeans and the
European Indo-Europeans that persists to the present.
