The ancient name of Tinsukia was Bangmara. It was the capital of Muttack Kingdom. Sarbananada Singha established his capital at Rangagarah situated in the bank of river Guijan. In 1791 A.D. he transferred his capital to Bengmara.

As per the direction of Sarbananda Singha, Godha Baruah dug a triangler shaped pond in Bangmara which is known as “Tinikunia Pukhuri”. In 1884 Dibru-Sadiya Rail line was constructed and a station was setup near the “Tinikunia Phukhuri” which was named as Tinsukia. Since then the City was popularly known as Tinsukia.

The muttack Kingdom occupied a distinct place in the history of Assam during the later part of the 18th century and the early part of 19th century.

The Moamareeyas or the Muttacks turned the history of the mighty Ahom Kingdom by leading the historic Moamareeya Rebellion, which may be described as the first socio-political movement in the history of Assam.
