Pre-history and myths

Assam and adjoining regions have evidence of human settlement from all periods of the Stone ages. That the known hills settlements belonged to earlier periods may suggest that the valleys were populated later, or it may reflect sampling bias due to mountainous areas being more likely to remain less disturbed over long stretches of time.

The earliest ruler according to legend was Mahiranga (sanskritized form of the Tibeto-Burman name Mairang). He was followed by others in his line: Hatak, Sambar, Ratna and Ghatak. Naraka removed this line of rulers and established his own dynasty. The Naraka king mentioned at various places in Kalika Purana, Mahabharata and Ramayana covering a wide period of time were probably different rulers from the same dynasty. Kalika Purana, a Sanskrit text compiled in Assam in the 9th and 10th century, mentions that the last of the Naraka-bhauma rulers, Narak, was slain by Krishna. His son Bhagadatta, mentioned in the Mahabharata, fought for the Kauravas in the battle of Kurushetra with an army of kiratas, chinas and dwellers of the eastern coast. Later rulers of Kamarupa frequently drew their lineage from the Naraka rulers.
