Pushyavarman (350–374) established the Varman Dynasty, by fighting many enemies from within and without his kingdom; but his son Samudravarman (374–398), named after Samudragupta, was accepted as an overlord by many local rulers. Nevertheless, subsequent kings continued their attempts to stabilise and expand the kingdom. The Nagajari Khanikargaon rock inscription of 5th century found in Sarupathar in Golaghat district of Assam adduces the fact that the kingdom spread to the east very quickly. Kalyanavarman (422–446) occupied Davaka and Mahendravarman (470–494) further eastern areas. Narayanavarma (494–518) and his son Bhutivarman (518–542) offered the "ashwamedha" (horse sacrifice); and as the Nidhanpur inscription of Bhaskarvarman avers, these expansions included the region of Chandrapuri "visaya", identified with present-day Sylhet division. Thus, the small but powerful kingdom that Pushyavarman established grew in fits and starts over many generations of kings and expanded to include adjoining possibly smaller kingdoms and parts of Bangladesh.
