The Mlechchha dynasty (c. 650 - 900) ruled Kamarupa from their capital at Harruppesvar in the present-day Tezpur, Assam, after the fall of the Varman dynasty. The rulers were aboriginals (local clan, genetically non-diverse), and like all other claimed lineages, 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.

But the distinct mention of Sala-stambha as being a lord of the Mlecchas, as in the Bargaon copper-plate of the 19th century, would appear to make it clear that he was a Bodo chief of the Mèch tribe (Sanskritised as Mlēccha), who followed Bhaskara-varman in assuming the rulership of Assam.
^The name Mech is almost a corruption of the Sanskrit word Mleccha i.e An outcast from the Brahmin point of view. (Endle 1911:81)
