For over a century, the question of who the people of the Sapta Sindhu were — and where they came from — has divided scholars. The traditional “Aryan invasion” thesis holds that horse-riding populations swept in from the steppes around 1500 BCE, bringing Sanskrit and the Vedic hymns with them, and displacing or subjugating an earlier civilization.
The archaeological record tells a different story. No layer of destruction, no mass grave, no sudden replacement of material culture marks the supposed invasion. Cities of the mature phase show gradual transformation, not conquest. The horse itself — central to the invasion argument — is nearly absent from the archaeological sites of the region in the relevant period, while the Rig Veda describes a landscape of great rivers, some of which, like the Sarasvati, are known to have dried up well before 1500 BCE — placing at least part of the hymns earlier than the invasion scenario allows.
Linguistic arguments, once considered decisive, rest on reconstructed proto-languages and migration models that recent genetic studies have both complicated and partly confirmed — showing gradual, mixed population movements over millennia rather than a single conquering wave. The picture emerging today is one of continuity and slow transformation, not rupture.
The archaeological, geographical, and genetic evidence, argument by argument — it’s all unpacked hymn by hymn in The 7 Rivers Civilization and Understanding the Rig Veda. [→ Discover the books]
