Despite the early misgivings of some scholars about such a correlation between language and race and the circular nature of many of the arguments, the concept of a common linguistic, cultural, biological, and historical heritage linking European and Indian peoples became internationally accepted as more fact than theory. Based on linguistic reconstructions, the prehistoric to historic chronologies of Europe and India were interpreted as reflecting various invasions of Indo-European or Indo-Aryan peoples who possessed a common cultural heritage, albeit remote. For Europe, this concept ultimately resulted in the disaster of the Third Reich, whereas in South Asia, the concept of Indo-Aryan peoples played a quite different cultural role.

However, in South Asian studies the concept of an Indo-Aryan invasion continues to be the main explanation for the cultural history of that region. The importance of these invasions is linked to the persistent opinion that the Indo-Aryan invaders were the authors of early Vedic (Sanskrit) literature, which is viewed as the foundation for all subsequent' 'Indian civilization.

The concept of an Indo-European or Indo-Aryan group of peoples has played a prominent role in interpretative studies of Old World history and archaeology. For almost 200 years, scholars and quasi scholars have attributed the linguistic, cultural, and racial affiliations of very disparate groups to a common Indo-Aryan heritage. In such widely seperated areas as Europe and India, many significant cultural changes recorded for the first and second millennia B.C. are attributed to an influx, or invasion, of Indo-Aryan peoples who shared a common cultural base and who were responsible for important socioeconomic and linguistic changes in the areas they invaded.
