Kamarupa is not included in the list of sixteen Mahajanapadas from the sixth to fourth centuries BCE; nor does it or the northeast Indian region find any mention in the Ashokan records (3rd century BCE)—it was not part of the Mauryan Empire. The 3rd-2nd century BCE "Baudhayana Dharmasutra" mentions Anga (eastern Bihar), Magadha (southern Bihar), Pundra (northern Bengal) and Vanga (southern Bengal), and that a Brahmana required purification after visiting these places—but it does not mention Kamarupa, thereby indicating it was beyond the ambit and recognition of the Brahminical culture in the second half of the first millennium BCE.
