Transitional Period

The Transitional Period spans the post-IVC world through to the emergence of historically verifiable dynasties. It encompasses the Late/Post-Harappan phase, the Painted Grey Ware (PGW) culture associated with the Kuru-Panchala kingdom, the arrival of Steppe-related ancestry (2,300–1,500 BCE), and the transition to iron technology.

The Sinauli discovery (2018) is this era's most significant finding. Three wooden chariots with copper coverings, helmets, antenna swords, and elite burials — C14-dated to 1,865–1,507 BCE — demonstrate organized warrior culture in the Ganga-Yamuna region. Whether these are war chariots (challenging the Steppe-origin narrative) or ceremonial ox-carts (consistent with it) remains debated.

The Narasimhan et al. 2019 study places the arrival of Steppe-related ancestry at 2,300–1,500 BCE. IVC populations mixed with Steppe groups to form Ancestral North Indians (ANI) and with peninsular groups to form Ancestral South Indians (ASI). Whether this genetic mixing brought Indo-European languages or occurred independently of language spread is the central open question.

By ~1,200 BCE, Painted Grey Ware culture appears in the Ganga-Yamuna doab — associated with the Kuru-Panchala kingdom of later Vedic texts. Hastinapura's PGW layers date to this period. Iron technology appears by ~1,000 BCE. The 16 Mahajanapadas (great kingdoms) consolidate by ~600 BCE, setting the stage for the historically verified Haryanka dynasty.
