The problem of localization of the ancestral homeland of Indo-European peoples has been facing science for a long time. As far back as the mid-18th century, the linguistic kinship of European peoples was noted, and in 1767, Kerdu pointed out the proximity of a number of European languages to Sanskrit, the language of the sacred texts of Ancient India "Vedas. "The decisive for the emergence of Indo-European studies was the discovery of Sanskrit, acquaintance with the first texts on it and the enthusiasm that began with ancient Indian culture, the most striking reflection of which was the book of F. von Schlegel" On the language and wisdom of Indians "(1808), writes V. N. Toporov . F. von Schlegel, the first to express the idea of a single ancestral home of all Indo-Europeans, placed this ancestral home on the territory of Hindustan. However, the fallacy of this assumption was soon proved, since before the arrival of the Aryan (Indo-European) tribes, India was inhabited by representatives of another language family and another one-time type - black Dravids.
Assumed at different times as the ancestral home of the Indo-Europeans (today this is the people of 10 language groups: Indian, Iranian, Slavic, Baltic, German, Celtic, Romance, Albanian, Armenian and modern Greek): India, the slopes of the Himalayas, Central Asia, Asian steppes, Mesopotamia , Near and Middle East, Armenian Highlands, territories from Western France to the Urals between 60 ° and 45 ° N, territory from the Rhine to the Don, Black Sea-Caspian steppes, steppes from the Rhine to Hindu Kush, areas between the Mediterranean and Altai, in Western Europe - currently, for one reason or another, most researchers rejected.
