The historical interactions between the indigenous tribal communities of the Arunachal Himalayas and the rulers of the Brahmaputra valley during the ancient period are primarily documented through which of the following sources?

💡 Solution & Explanation

Historical interactions between the hill tribes of Arunachal Pradesh and the valley kingdoms of Kamarupa are chronicled through regional copper plate inscriptions, stone grants, and indigenous historical chronicles known as buranjis. These records detail reciprocal trade in forest produce, salt, and iron implements, alongside occasional military expeditions or peace pacts. Greek accounts did not penetrate the deep northeastern frontier, and Mauryan edicts are absent from the Arunachal region. Copper plate grants provide precise epigraphic evidence of land endowments and tributary relationships.
