Explanation:

The Varman dynasty 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 independent state remained umimpaired. According to the Allahabad Prasasti, the ruler of Kamarupa was a frontier ruler (Pratyanta-nrpatis) of the great Gupta emperor. 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.
