The references to Davaka comes from the 4th century Allahabad pillar inscription of Samudragupta, where it is mentioned as one of five frontier kingdoms of the Gupta Empire; the Shung-Shu History of the Liu Song dynasty, where the kingdom is named Kapili (now the name of a river); the Gachtal stone pillar inscription written in Kamrupi language. N K Bhattasali has identified it with Dabaka in modern Nagaon district, with the kingdom associated with the Kopili-Kolong river valley.
In 4th-century Davaka was mentioned as frontier kingdom with Kamarupa in the Samudragupta's Prayaga stone inscription. Historians like Kanak Lal Barua (1933) claim Davaka was an aboriginal Austric-Dravidian kingdom which was later absorbed by 6th or 7th century by western kingdom of Kamarupa, though later historians like B N Puri (1968) and P C Choudhury (1959) claim that it was absorbed much earlier in the first half of the 5th century during the reign of Kalyana Varman (422-446).
