What happened

The oldest layer of what became Hinduism took shape as the religion of Sanskrit-speaking peoples whose hymns were later collected into the Rig Veda and three companion Vedas, the Sama, Yajur, and Atharva. Vedic religion centered on fire sacrifice conducted by Brahmin priests, addressed to sky and nature gods including Indra, Agni, and Rudra, the deity later identified with Shiva, and involved the ritual drink soma. Each Veda was later divided into layers: Samhitas of hymns, Brahmanas explaining the rituals, Aranyakas for forest hermits, and Upanishads, philosophical texts appended at the end. The entire corpus was transmitted orally, memorized with word-for-word phonetic precision across generations by priestly lineages, and was not committed to writing until long after its composition. Historians place the Rig Veda's core composition around 1500 to 1000 BCE, though how Sanskrit-speaking Vedic culture arrived in the Indus region, whether by migration from Central Asia or as an indigenous development, remains one of the most contested questions in South Asian history.

Why it matters

Vedic ritual religion supplied the priestly class, the sacrificial vocabulary, and the god-names that all later Hinduism built on or reacted against, and the Upanishads and philosophical schools that followed presented themselves as extensions of the Vedas rather than replacements for them. The fact that the entire Vedic corpus survived by memory alone, without writing, for centuries is itself treated by scholars as one of the most disciplined oral transmission systems in human history.

How we know

There is no archaeological Rig Veda text; dating rests on comparative linguistics and the hymns' own internal references, both of which different scholars read differently, while the ritual and social content of the Vedas is corroborated across the Samhita, Brahmana, and Upanishad layers of the surviving oral-then-written corpus.
