[10] It extended over almost the entire region of present districts of Lakhimpur, Dhemaji, Tinsukia, and some parts of Dibrugarh in Assam,[11] as well as the plains and foothills[12] of Arunachal Pradesh.

[31] The earliest Chutia king in the epigraphic records is Nandin or Nandisvara, from the latter half of the 14th century,[32] mentioned in a grant by his son Satyanarayana who nevertheless draws his royal lineage from Asuras in his mother's side who were "enemies of the gods".

[33] The mention of Satyanarayana as having the shape of his maternal uncle (which is also an indirect reference to the same Asura/Daitya lineage)[34] may also constitute evidence of matrilineality of the Chutia ruling family, or that their system was not exclusively patrilineal.

[8] Brahmanical influence in the form of Vaishnavism reached the Chutia polity in the eastern extremity of present-day Assam during the late fourteenth century.

[45] This deity, noticed in the 10th century Kalika Purana well before the establishment of the Chutia kingdom, continued to be presided by a Deori priesthood well into the Ahom rule and outside Brahminical influence.

[59] A late discovery of an inscription, published in a 2002 souvenir of the All Assam Chutiya Sanmilan[69] seems to genealogically connect the last historically known king, Dhirnarayan with Neog's list above.

[77] Nevertheless, it is estimated by most modern scholarship that Chutias held the areas on the north bank of Brahmaputra from Parshuram Kund (present-day Arunachal Pradesh) in the east and included the present districts of Lakhimpur, Dhemaji, Tinsukia and some parts of Dibrugarh in Assam.

[86] During the same era (late 14th century) Gadadhara, the younger brother of Rajadhara and a descendent of Candivara in order to expand his influence collected a large army at Borduwa and attacked the Chutiyas and Khamtis but was held captive, he was later set free and had to settle at Makhibaha (in present-day Nalbari district).

[87][88] Suhungmung, the Ahom king, followed an expansionist policy and annexed Habung and Panbari in either 1510 or 1512, which, according to Swarnalata Baruah, was ruled by Bhuyans[89] while according to Amalendu Guha, it was a Chutia dependency.

[96] As a reward for the assistance, the Ahom king settled this Bhuyans in Kalabari, Gohpur, Kalangpur and Narayanpur as tributary feudal lords.

[98][99] The rest of the royal family was dispersed, the nobles were disbanded and the territory was placed under the newly created office of the Sadiakhowa Gohain.

These people were settled in the Bosa (Doyang) and Ujoni regions and asked to build iron implements like knives, daggers, swords as well as guns and cannons.
