Varman dynasty The Varman dynasty (350-650) is the first historical dynasty of the Kamarupa kingdom. It was established by Pushyavarman, a contemporary of Samudragupta.[2][3] This dynasty became vassals of the Gupta Empire, but as the power of the Guptas waned, Mahendravarman (470-494) performed two horse sacrifices and threw off the imperial yoke.[4] The first of the three Kamarupa dynasties, the Varmans were followed by the Mlechchha and then the Pala dynasties.
