Pragjyotisha is a mythological kingdom that is mentioned in a multitude of Hindu epics. It came to be associated with the historical Kamarupa[1] after Bhaskaravarman of the Varman dynasty by drawing his lineage from Naraka/Bhagadatta of the legendary Pragjyotisha to bring his peripheral kingdom closer to mainland traditions at a time when he was emerging as a powerful king with interests in North India.[2] The identification with the mythical Naraka/Bhagadatta lineage continued to be used by the Mlechchhas and Palas for roughly similar purposes.[3]
^"Considering the historical content of the seventh century Kāmarūpa, especially during the reign of Bhāskarvarman when the Varmans was ascending to one of the important powers in north India, it appears that they projected Kāmarūpa on a larger geopolitical map by combining it with Prājyotisa, the Epic kingdom. In other words, Prājyotisa was retrieved from the ancient Epic past by the aspirant local kingship to overcome this peripherality. An elusive mythical space was brought into the actual geography of Kāmarūpa" (Shin 2018, p. 38)
