In 4000 BC, Indo-European was spoken somewhere, but its location is very controversial.
Broadly speaking, three major economic lifestyles were in competition in Central Europe during 5th and 4th Millenia BC. These were
This was the era of the ``Secondary Products Revolution'' with inventions like cheese, leather, beer, and, most notably, the wheeled wagon. (Cast copper axles have been discovered near the Cucuteni dominion dated to the 5th millenium BC; and Kurgans are known to have bridled horses for riding by 4000 BC.)
By 4000 BC, three mixed-farming (dairy) cultures were in competition in East Central Europe; these were
(Again, dating is approximate: Tripolye was being replaced with later cultures while TRB/Funnel was just emerging.)
There is no universal agreement on which of these three groups provided the proto-Indo-European language, and you can find sober scientists guessing that Indo-European was spoken by any combination of these groups, including none or all three!
Although all three of these groups -- Tripolye, Sredny Stog, and Funnel Beaker -- could be described as ``early dairy farmers;'' in fact the cultures were quite distinct: Tripolye was an organized village society with egalitarian matriarchal customs; Sredny Stog was a semi-nomadic patriarchal society which stressed individualistm; the haphazard lifestyle of Funnel Beaker villagers betrays their recent development from unsettled foragers.
(Cereal farming stresses patience, while stockbreeding requires physical strength -- this may explain why domesticating large animals changes a matriarchal society to patriarchal. Furthermore, the contrast between land-fixed self-growing crops and mobile animals needing to be tended, may help predict whether ancient economics will be based on communal or individual property rights.)
The geographical placements on the map are only approximate. Moreover there was overlap: Kurgan tombs from this era are found as far West as Czechoslovakia, while Tripolye had settlements in central Ukraine. Finally, the indicated cultures are only roughly contemporaneous: Lengyel was 5th millenium, and TRB/Funnel Beaker mainly 4th millenium.
With sophisticated mining, smelting and casting, this era might be called the ``Advanced Copper Age.'' There were metallurgical centers in the Karanovo area in the Balkans, as well as in West-Central Asian areas accessible to Kurgan traders, and the Carpathian Mountains, situated roughly at the central point between the three competing dairy cultural styles, was a rich source of copper ore.
But, although the Bronze Age would begin to emerge 1000 years later, archaeological evidence suggests that by 4000 BC the Balkan metal industry was entering a ``Dark Age'' lasting several centuries. Was this apparent conflict related to competition by the competing dairy cultures being played out in the fertile Danube Basin just to the North of the Balkans?
A thousand years later, new cultures have emerged, and the locations of Indo-European branches can be inferred. (It is good to remember that there was rapid change even in prehistoric times -- Europe's population may have tripled between 4000 and 3000 BC, although both dates fall in the ``Late Neolithic.'')
Again dates and places are very approximate: The Bell Beaker culture emerged almost 1000 years after Globular Amphora.
Although Indo-European languages do not enter the historical record until the 2nd millenium BC, one can infer, with some confidence, much of Indo-European geography by the third millenium. Most supporters of both the Gimbutas Kurgan Theory and Danubist or Anatolian hypotheses would agree that Usatovo culture can be tentatively identified with the first speakers of proto-Greek, and both theories usually identify Tocharian with the Afanasievo culture far to the East in Asia. Similarly the identifications of Indo-Iranian with Yamnaya, Balto-Slavic with Battle Axe, and Germanic with Corded Ware (see below) are not controversial. Most of the other identifications shown in the map might also be tentatively accepted by theorists on both sides of the Kurgan-Danubian debate.
In other words, many would agree that the Balkan-Pontic area
of the 5th or 4th millenium BC was a locus for early Indo-European expansion;
the debate is whether Tripolye ``converted'' the Kurgans to speak I-E,
or vice versa!
For most experts, the signs of Kurgan culture among the early
Indo-European speakers are unmistakable.
As just one example, the warrior heroes in Homer's Iliad
are buried in Kurgans (though of course Homer doesn't use that Russian word).
In the map above, it should not be inferred that the Battle-Axe people spoke ``proto-Balto-Slavic,'' nor that the Yamnaya people spoke ``proto-Indo-Iranian.'' The languages had diverged too recently for that. Instead both groups spoke the same language, called ``Late Indo-European'' or ``proto-Satem,'' but were developing divergent dialects which after a few more centuries would become the familiar distinct proto-languages of the Indo-European group. Only proto-Anatolian (and probably a few other Centum branches) existed as distinct Indo-European languages in 3000 BC.
Proto-Indo-European has been reconstructed and shown to contain many words related to horses and stockbreeding. The word kwe-kwlo (cognate of wheel and cyclos) is reconstructed for the wheel, but in all theories besides Gimbutas', proto-Indo-European had already separated into its branches before the wheel was invented.
Opponents of Gimbutas' theory of Indo-European origin base their case on five assumptions:
Let me answer these ``charges'' one by one:
Finally, the genetic language tree of Indo-European would have a different structure if Celtic and Italic were spoken in Central Europe before the Kurgan intrusions. I try to explain that on a separate page, but briefly:
Baltic Battle Axe and German Corded Ware were sibling cultures, and some scientists hardly distinguish the two. Yet, Baltic seems to be the Indo-European branch which most closely preserves the prehistoric proto-Indo-European language, while Germanic has undergone major changes in grammar, phonology, and lexicon.
While the position of Germanic in the Indo-European tree is controversial, it has close affinities to Baltic and Slavic, and many theorists speak of a ``Germano-Balto-Slavic branch.'' Yet the single most important ``split'' in Indo-European is the Centum/Satem divide; Baltic and Slavic are Satem languages while Germanic is Centum like Italic.
Do the prehistories of Battle-Axe/Corded-Ware culture and the early Germano-Balto-Slavic language shed light on each other?
The reason Baltic preserves ancient Indo-European most closely is that any pre-Kurgan culture in the Baltic was weakish, small population (prob. emphasized hunting and fishing rather than farming), and may have spoken a sibling of Old Kurgan already. The Corded-Ware invaders into present-day Germany, however, encountered the entrenched Funnel-Beaker Folk, who resisted Corded-Ware culture for several centuries. Germanic evolved as a hybrid language, with elements of
The term ``language hybrid'' may offend professional linguists, since independent languages don't ``interbreed.'' But mutually intelligible dialects of the same language do interbreed and during the Corded-Ware expansion Baltic and Italic speakers could probably make a little sense of each other, as the common ancestor was only a few centuries in the past. (Similarly, Saxon and Viking languages were partly mutually intelligible at the time of early Saxon-Viking rivalry in Britain.)
The very name ``Corded-Ware'' provides a strong affirmation of the Gimbutas Theory. This refers to leather cords which were added to pottery as ornaments. (Anti-Gimbutists don't like to admit it but before the advent of Corded-Ware, the Kurgan people were applying cord ornaments to pottery.) The relationship between cord and ornament is preserved in Germanic languages! Consider two cognates in Dutch:
