It gets its name from the Vedas, which are liturgical texts containing details of life during this period that have been interpreted to be historical and constitute the primary sources for understanding the period . </P> <P> The Vedas were composed and orally transmitted by speakers of an Old Indo - Aryan language who had migrated into the northwestern regions of the Indian subcontinent early in this period . The associated Vedic culture was tribal and pastoral until c. 1200 or 1100 BCE and centred in the Punjab . It then spread eastward to the western Ganges Plain, becoming more agricultural and settled, while the central Ganges Plain was dominated by a related but non-Vedic Indo - Aryan culture . The Vedic period saw the emergence of a hierarchy of social classes and the coalescence of peoples into Janapada (monarchical state - level polities). The end of the Vedic period witnessed the rise of Mahajanapada (large, urbanised states) as well as śramaṇa movements (including Jainism and Buddhism) which challenged the Vedic orthodoxy of the Kuru Kingdom . </P>
