Models of the Indo-Aryan migration discuss scenarios of prehistoric migrations of the proto-Indo-Aryans to their historically attested areas of settlement in the northwest of the Indian subcontinent.

Claims of Indo-Aryan migration are drawn from linguistic evidence but also from a multitude of data stemming from Vedic religion, rituals, poetics as well as some aspects of social organization and chariot technology.Indo-Aryan language derives from an earlier Proto-Indo-Iranian stage, usually identified with the Bronze Age Sintashta and Andronovo culture north of the Caspian Sea.

Their migration to and within Northwestern parts of South Asia is consequently presumed to have taken place in the Middle to Late Bronze Age, contemporary to the Late Harappan phase (ca.

1700 to 1300 BCE).This period is marked by a gradual and continual shift of the population to the east, first to the Gangetic plain with the Kurus and Panchalas, and further east with the Kosala and Videha.

This Iron Age expansion corresponds to the black and red ware and painted gray ware cultures.
