Avantivarman is believed to be the last king of the Varman dynasty of Kamarupa in present-day North-East India.
No direct evidence of this king exists, nor does this name appear anywhere in a historical record — the name Avanti Varma itself is reconstructed from the benedictory verses of a Sanskrit play Mudrarakshasa by Vishakhadatta.
[2] According to Bargaon grant of Ratnapal, Mlechchha king Salasthambha took over the rule of Kamarupa from the descendants of Naraka.
Barua states that there was a Mlechha revolt in Kamarupa and the leader of the Mlecchas usurped the throne by deposing Bhaskaravarman's immediate successor Avantivarman.
[4] Mukunda Madhava Sharma theorizes that Salasthambha must have overthrown the immediate successor of Bhaskaravarman.
