In fact, some important scholars argue that, in addition to the aforementioned Indo-European linguistic unity, it is possible to identify a common heritage at the social level. and cultural, in other words a minimum of common Indo-European culture.
This minimal cultural common denominator becomes apparent through comparisons attempted at the level of social organization, religion and mythology.
According to this theory, in the Indo-European societies of antiquity a three-part form appears, a three-part hierarchical structure, which is a component of the Indo-European social and cultural identity.
This three-part distinction at a social level (priests, warriors, cultivators of the earth) is also reflected in the religious field, with corresponding distinctions of deities.
In the context of the so-called “tripartite” theory, which was briefly set out in the above lines. Cultural similarities in ancient Indo-European societies are evidence of a distant cultural unit, an “Indo-European cultural edifice”.
Of course, the conclusion reached by the “tripartite” theory is not There were ancient societies with a similar tripartite organization and similar institutions that did not belong to the Indo-European linguistic space, and on the other hand the archaeological evidence does not support a strongly hierarchical social organization in the distant prehistory, where the origin of the Indo-European is placed. On a much more solid basis than the aforementioned theory of an Indo-European cultural edifice is the study of the so-called vocabulary of the Indo-European institutions, ie the unquestionable formal similarities observed in related terms of various Indo-European, e.g. “King” in Latin, ancient Indian and Irish language). However, the linguistic data that we have at our disposal in this case, although they suggest through the comparative study some primitive linguistic form, are not sufficiently enlightening as to the meaning of these terms, since the meanings change despite the preservation of the formal similarities.
