Our knowledge about the original home of the Aryans is still in a speculative stage.
There has been a great divergence of opinion in the matter of identification of the place wherefrom the Aryans came into India. No firm conclusion is, therefore, possible in this regard
The problem of identification of the original home of the Aryans has to be approached from both linguistic and racial points of view. As early as the sixteenth century Filippo Sassetti, a Florentine, during his long stay in India noticed a definite relation between Sanskrit and some of the principal languages of Europe.
But it was Sir William Jones who in 1786 showed that Sanskrit and the European languages such as Greek, Latin, German, Celtic, Gothic, as also the Persian, had a common origin. The scholars have named this language group as Indo-European or Indo-German language group. Max Muller also emphatically pointed out that scientifically speaking, Aryan means language and not race.
From this language affinity it is argued that the Indo-European languages, at least a large number of them, are crowded in Europe and some of them are found to stretch out in a narrow length reaching upto the region of the Punjab in the early Rig Vedic time. This has led many a scholar to conclude that the original home of the Aryans was Europe rather than India. They support their conclusion by pointing out that comparative philology has shown that the Lithuanian language is the only language that retains the basic Aryan idioms even today.
Penka and his school of thought, particularly Kossuna, approached the problem of the Indo-Aryans from racial point of view and concluded that Germany was the original home of the Indo-Aryans.
From the above approaches the claim that India was the original home of the Aryans becomes untenable. However, some scholars, such as Gananath Jha, D. S. Triveda, L. D. Kalla, are advocates of the theory of indigenous origin of the Aryans. While J ha seeks to prove that Brahmarshi-Desha was the original home of the Aryans, Triveda mentions the region of the Devika River in Multan, and Kalla claims Kashmir and the Himalayan regions as the original home of the Aryans.
