The Varman dynasty (350–650) was the first historical dynasty of the Kamarupa kingdom. It was established by Pushyavarman, a contemporary of Samudragupta. The earlier Varmans were subordinates of the Gupta Empire, but as the power of the Guptas waned, Mahendravarman (470–494) performed two horse sacrifices and the status of Kamarupa as an independent state remained unimpaired. As per the Apsad Inscription of Adityasen, Susthivarman was defeated by Mahasengupta on the bank of Lauhitya. The first of the three Kamarupa dynasties, the Varmans were followed by the Mlechchha and then the Pala dynasties.

Kamarupa, an early state during the Classical period on the Indian subcontinent, was the first historical kingdom of Assam.
