The Mlechchha dynasty (c. 650 - 900) ruled Kamarupa from their capital at Hadapeshvar in the present-day Tezpur, Assam, after the fall of the Varman dynasty. The rulers were aboriginals, though their lineage from Narakasura was constructed to accord legitimacy to their rule. According to historical records, there were twenty one rulers in this dynasty but the line is obscure and the names of some intervening rulers are not known. The Mlechchha dynasty in Kamarupa was followed by the Pala kings.
According to some historians, the remnant of the Mlechchha kingdom formed the later Kachari kingdom  based in Dimapur and the Sutiya kingdom based in Sadiya after being driven south and east by Brahmapala of the Pala dynasty.
