Assam, Mlechchha Dynasty, Tyagasimha (890-900 AD), Heavy Bell Metal Unit, 19.30 gms, ‘Ta’, in Brahmi, letter attributed to Tyagasimha, extremely fine, very rare. Note: Tyagasimha was the last known ruler of the Mlechchha dynasty, which ruled the ancient kingdom of Kamarupa (present-day Assam) from approximately 650 to 900 AD. After Tyagasimha’s death without an heir, the Mlechchha dynasty came to an end. The local people then chose Brahmapala, leading to the establishment of the subsequent Pala dynasty of Kamarupa after 900 AD. "Mlechchha" was a generic term used in ancient Indian texts to denote foreigners, "barbarians" or people of non-Vedic origins, much like the Greek "barbaros". This suggests the rulers were likely indigenous tribal chiefs (possibly of Bodo-Kachari or Mech origin) who were considered outsiders to mainstream Indo-Aryan society before their integration into the political landscape.
