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.

According to the map prepared by Captain Hemilton Vetch in 1841, a large portion of present Dibrugarh and Tinsukia district had been identified as "Bengmara Country of Moamareeya Tribe" with its capital at Bengmara (present Tinsukia). In the history of Assam, this Bengmara Country was later popularly known as Muttack Country of Soumar, early name of a region in the North East corner of Assam.

The First King of Muttack Kingdom was Swargadeo Sarbananda Singha. Sarbananada Singha established his capital at Rangagarah situated in the bank of river Guijan. In 1791 A.D. he transferred his capital to Bengmara.

Apart from the these ponds there are many ancient roads constructed in different parts of the Muttack territory. Godha-Borbaruah road, Rangagarah road, Rajgor road and Hatiali road were main roads within the territory.

After becoming King, Mezara adopted the name Sarbananda Singha. Sarbananda Singha introduced coins after his name. In Saka 1716 and 1717 he inscribed the title Swargadeo in the coins.
