Indo-Aryan Migration refers to the movement of Indo-European speaking peoples into the Indian subcontinent, which is believed to have occurred around 1500 BCE. This migration played a crucial role in shaping the cultural and linguistic landscape of ancient India, contributing to the development of the Vedic texts, including the Rig Veda, Sama Veda, Yajur Veda, and Atharva Veda. These texts are foundational in understanding the beliefs, rituals, and social structures that emerged as a result of this migration.
