In this essay I wish to discuss the language spoken by the people of Leubingen and its subsequent development. The development of language in the Unetice cultural areas is inextricably linked to the DNA of their populations. As Gustav Kossinna demonstrated in his The Indo-Germanics: An Outline: Part 1: The Proto-Indo-Germanics and The Origin of the Germanics: On the Method of Settlement Archaeology (both translated into English from German by Trevor Sutcliffe), a material culture in its entirety is ultimately linked to and is the possession of the people who created it and the same can be said for language, in my opinion.
'Sharply defined archaeological cultural areas correspond unquestionably
with the areas of particular people or tribes.' (Kossinna's Law)
In other words, a unified culture is the product of a unified ethnicity, not withstanding that individual elements of that culture may be present in other ethno-cultures through trade or copying. The key word to emphasise here is unified. I believe that DNA studies are finally vindicating Kossinna's theory.
Returning now to the issue at hand, the language spoken by the Unetice culture or more specifically the community at Leubingen. In 1950 BCE, the approximate date of the Leubingen burials, the Germanic and Celtic languages did not yet exist, but obviously the ancestors of those who spoke those languages did exist and so did the ancestral language(s) of Germanic and Celtic. Proto-Celtic, the hypothetical original language of the Celtic dialects did not arise until about 1300-800 BCE, and Proto-Germanic is even later at 500 BCE to 200 CE. Thus Proto-Celtic (southern branch of Unetice) broke away from Proto-Indo-European (Proto-Indo-Germanic, as it is known in the German speaking world) much earlier than Proto-Germanic (northern branch of Unetice) and for this reason Celtic civilisation is much older than the Germanic.
Proto-Celtic started to emerge with the Urnfield and the early Hallstatt cultures. Prior to this point in time the ancestor of Proto-Celtic is an early Northwest Indo-European dialect, from which Proto-Germanic and Proto-Italic also emerged. An alternative name for 'North-West-Indo-European' (NwIE) is 'Italo-Celtic-Germanic'. This was the language likely spoken by the inhabitants of the Unetice Bronze Age community at Leubingen. I believe that it would be appropriate to call this language-'Celtic-Germanic'. Proto-Germanic started to emerge with the Nordic Bronze Age and Jastorf cultures.
Just as Proto-Celtic and Proto-Germanic developed from NwIE so did the peoples themselves, the Celts and the Germanics, and this is reflected in their similar DNA, consisting of shared Yamnaya derived steppe ancestry, Neolithic European Farmer ancestry and Western Hunter Gatherer ancestry. It is the Yamnaya ancestry, the largest shared element which was the Indo-European speaking component and is reflected in R1b and R1a lineages. Across the Germanic and former Celtic speaking worlds these two haplogroups are dominant, most especially R1b which is shared by people of Germanic and Celtic ancestry. Both Proto-Celts and Proto-Germanics descend from the Bell Beaker, Unetice and Tumulus cultures. By the time that the Germanics and Celts developed into separate and distinct cultures their genetic admixtures changed slightly but the shared deep ancestry remained as it still does today.
The cause of the breakdown of NwIE is due to the subsequent geographical isolation of the Proto-Germanics with the onset of the Nordic Bronze Age, creating different trade networks from the Proto-Celts with their Urnfield and Hallstatt networks. The dramatic sound shifts which affected the northern branch of the Unetice culture was responsible for the development of Germanic into a separate language (Grimm's Law, Verner's Law, et cetera). As Proto-Germanic and Proto-Celtic developed into separate languages so did their material cultures along with slight changes in genetic admixtures.
The Unetice culture is a fascinating one as it represents a culture from which both the Germanics and Celts descend from and is thus worthy of more study and discussion, which I intend to continue (the gods willing) on this blog.
