The ancient names of Assam were Kamrupa and Pragjyotisa, which had been inhabited by the Kirata or Mongoloid people before the Aryan culture could spread its influence over the North Eastern part of India. Before the advent of the Aryan civilization, the Austric-Mongolian and Dravidian culture was the prevalent culture of the people of this area. According to some scholar, the Aryans advent in North East India was occurrence of the pre-Buddhist period. The period of the Brahmins was followed by (...) the Buddhist period, so far as the cultural history of India is concerned. In comparatively, ancient inscriptions of Assam, we find that, the high caste Aryans like Brahmans, Shatriyas and Kalitas entered into Assam and began to settle here even during the Pre-Christian era. The mention of Kamrupa and Devoka in the Allahabad pillar inscription of the Gupta king Samudragupta has an important bearing on the Aryanisation of North East India. In the domain of political system, it is all probable that the ancient Assam populated by the non-Khmer group of the Austric and the Tibeto-Burman people was in tribal state of society. Narakasura and Bhagadutta, the legendary kings of Assam were probably the first monarchical rulers and they were in all probability the Aryanised or Hunduised Mongoloid persons. In other words, the tribal political system of Assam was changed into monarchical system by the influence of the Aryan culture. (shrink)
