The Kapili-Jamuna Valley is situated in the present districts of Nagaon, Marigaon and Hojai in Central Assam and is formed by the rivers Kapili, Jamuna and their tributaries. The presence of these rivers has made the region very fertile, attracting human habitation from remote pasts. The Sri Rajamalastates that in early times the kingdom of Trivega was located in the fertile tracts of the Kapili-Jamuna and Kalang Valley. The Allahabad pillar inscription of Samudra Gupta, datable to 4th century C.E, mentions Devaka (Doboka of the Kapili-Jamuna Valley) along with the kingdom of Kamarupa whose rulers paid nominal allegiance to the Gupta monarch. But by the second quarter of the fifth century C.E, sources would indicate that the kingdom of Devaka had broken off from the Gupta suzerainty. Again, in course of time, by sixth century C.E the Kapili-Jamuna valley was incorporated in the kingdom of Pragjyotisa-Kamarupa. In spite of the dearth of literary and epigraphic sources in constructing the history of the region, the abundance of material remains in the form of temple ruins and sculptures throughout the valley would indicate the presence of a flourishing kingdom, whose rulers patronized temple building activities and different artistic traditions. The region’s history, illuminated mainly through archaeology forms an important chapter in the history of Assam and thus needs to be carefully assessed
