A cultural tradition refers to persistent configurations o f basic technologies and cultural systems as well as structure within the context of temporal and geographic continuity.

That the archaeological record and ancient oral and literate traditions of South Asia (ie. the Vedic tradition) are now converging has significant implications for regional cultural history. A few scholars have proposed that there is nothing in the 'literature' firmly placing the Indo-Aryans, the generally perceived founders of the modern South Asian cultural tradition(s), outside of South Asia, and now the archaeological record is confirming this. Within the context of cultural continuity described here, an archaeologically significant indigenous discontinuity occurs due to ecological factors (ie. the drying up of the Sarasvati river). This cultural discontinuity was a regional population shift from the Indus Valley, in the west, to locations east and southeast, a phenomenon also recorded in ancient oral (ie. Vedic) traditions. As data accumulates to support cultural continuity in South Asian prehistoric and historic periods, a considerable restructuring of existing interpretive paradigms must take place. We reject most strongly the simplistic historical interpretations, which date back to the eighteenth century, that continue to be imposed on South Asian culture history. These still prevailing interpretations are significantly diminished by European ethnocentrism, colonialism, racism, and antisemitism. Surely, as South Asian studies approaches the twenty-first century, it is time to describe emerging data objectively rather than perpetuate interpretations without regard to the data archaeologists have worked so hard to reveal.

Taken together, the above traits establish that despite significant differences, urban developments in the Indus-Sarasvatī and Ganges regions do belong to ‘a single Indo-Gangetic cultural tradition which can be traced for millennia’; in the words of Jim Shaffer, ‘a continuous series of cultural developments links the so-called two major phases of urbanization in South Asia’, the Harappan and the historical. His conclusion is plain: ‘the essential of Harappan identity persisted’.
