The Chutia kingdom[8] (also Sadiya[9] or Chutiya) (Pron: /ˈsʊðiːjɑː/ or Sutia) was a late medieval state that developed around Sadiya in present Assam and adjoining areas in Arunachal Pradesh.[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.[13] The kingdom fell around the year 1524 to the Ahom Kingdom after a series of conflicts and the capital area ruled by the Chutia rulers became the administrative domain of the office of Sadia Khowa Gohain of the Ahom kingdom.[14]
The Chutia kingdom came into prominence in the second half of the 14th century,[15] and it was one among several rudimentary states (Ahom, Dimasa, Koch, Jaintia etc.) that emerged from tribal political formations in the region after the fall of Kamarupa kingdom, between the 13th and the 16th century.[16] Among these, the Chutia state was the most advanced,[17][18] with its rural industries,[19] trade,[20] surplus economy and advanced Sanskritisation.[21][22] It is not exactly known as to the system of agriculture adopted by the Chutias,[23] but it is believed that they were settled cultivators.[24] After the Ahoms annexed the kingdom in 1523, the Chutia state & its population was absorbed into the Ahom kingdom through Ahomisation — the nobility and the professional classes were given important positions in the Ahom officialdom[25][26] and the land was resettled for wet rice cultivation.[27]
^"(T)he Chutiyas seem to have assumed political power in Sadiya and contiguous areas falling within modern Arunachal Pradesh." (Shin 2020:51)
^"Their kingdom called Sadiya extended in the north over the entire region from the Sisi in the west to the Brahmaputra in the east. The hills and the river Buri Dihing formed its northern and southern boundaries respectively. Thus the Chutiya territory extended over almost the entire region of present districts of Lakhimpur, Dhemaji, Tinsukia, and some parts of Dibrugarh." (Gogoi 2002:20–21)
^(Shin 2020:57) "The ruins of two forts in Lohit district of Arunachal Pradesh is said to be the remains of Bhīṣmaka's city, viz. Bhismaknagar (sk.
Bhīṣmakanagara): one ruin about 16 miles northwest of Sadiya at the foot of the hills between the rivers Dikrang and Dibang is known as the fort of Bhīṣmaka, and the other about 24 miles north of Sadiya between the gorges of those two rivers is believed to be the fort of Śiśupāla. Based on an inscribed brick with the name of Śrīśrī-Lakṣmīnārāyaṇa, discovered from the ruins of the forts in Bhismaknagar, it is assumed that Chutiya king Lakṣmīnārāyaṇa of the early fifteenth century had his capital in the area. The paleographical analysis of the inscription supports this dating."
^"In the main, however, their territory was confined to the river valleys of the Suvansiri, Brahmaputra, Lohit, and the Dihing and hardly extended to the hills at its zenith."(Nath 2013:27)
^"The Chutiya power lasted until 1523 when the Ahom king Suhungmung, alias Dihingia Rāja (1497–1539), conquered their kingdom and annexed it to his sphere of influence. A new officer of Ahom state, known as Sadiya Khowa Gohain, was appointed to administer the area ruled by the Chutiyas." (Shin 2020:52)
^"It is more likely that if there was a Chutiya state at this time, it was of little significance until the second half of the fourteenth century." (Shin 2020:52)
^"The period from the 13th to the 16th century saw the emergence and development of a large number of tribal political formations in northeast India. The Chutiya, the Tai-Ahom, the Koch, the Dimasa (Kachari), the Tripuri, the Meithei (Manipuri), the Khasi (Khyriem), and the Pamar (Jaintia)—all these tribes crystallised into rudimentary state formations by the 15th century." (Guha 1983:5)
^"The most developed of the tribes in the 15th century were the Chutiya." (Guha 1983:5)
^"Indeed it appears that of all the tribes of the Brahmaputra valley, the Chutiyas were the most advanced and had a well-developed civilization."(Datta 1985:29)
^"The growth of a number of professions among the people of this kingdom like tanti (weaver), kahar (bell-metal worker), sonari (goldsmith) ... indicates the growth of some rural industries among the Chutiyas." (Gogoi 2002:22)
^"(T)he Chutias, who held power by regulating the easterly trade and migration of people to and from Tibet, Southern China, and Assam." (Saikia 2004:8)
^"(T)he Chutiyas were one of the earliest tribes to be Hinduised and to form a state, may point to their surplus economy." (Gogoi 2002:21–22)
^(At the time of annexation by the Ahoms) caste system had become prevalent in (the Chutiya) society." (Gogoi 2002:21)
^"It is not definitely known as to the system of agriculture adopted by them." (Gogoi 2002:22)
^"It must be noted, however, that the word 'khā' of Tai-Ahom language, which is usually prefixed to names of non-Ahom people practicing shifting cultivation, does not appear for the Chutiyas, probably because they were neither stateless nor were they solely shifting cultivators in the early phase of Ahom rule. There seems no serious interaction between the Ahoms and old settled people of the neighborhood including the Chutiyas until the fourteenth century." (Shin 2020:51)
^"The Ahoms accepted many Chutiyas to their fold and offered them responsible offices in the administration"(Dutta 1985:30)
^"[T]he Chutiya kingdom consisted of a vast plan level and fertile territory which provided for the Ahoms possibility of easy extension of wet rice culture in the region." (Gogoi 2002:22)
