==History== ===Medieval period=== ====Chutia Kingdom==== The medieval Chutia Kingdom was on the bank of the river Brahmaputra. It was a powerful kingdom which had ruled in northeastern Assam and the plains and foothill areas of present-day Arunachal Pradesh, with the capital at Sadiya. The kingdom controlled almost the entire region of present Assam districts of Lakhimpur, Dhemaji, Tinsukia and Dibrugarh as well as parts of Sonitpur, Golaghat, Jorhat and Sivasagar districts. In Arunachal Pradesh, it covered the districts bordering Assam.

====Ahom Kingdom==== The Ahom Kingdom was a kingdom in the Brahmaputra valley in Assam that maintained its sovereignty for nearly 600 years and successfully resisted Mughal expansion in North-East India. Established by Sukaphaa, a Tai prince from Mong Mao, it began as a Mong in the upper reaches of the Brahmaputra River. It expanded suddenly under Suhungmung in the 16th century after annexing the Chutia kingdom and parts of Kachari kingdom and therefore became multi-ethnic in character. The kingdom became weaker with the rise of the Moamoria rebellion, and subsequently fell to a succession of Burmese invasions. With the defeat of the Burmese after the First Anglo-Burmese War and the Treaty of Yandabo in 1826, control of the kingdom passed into British (East India Company) hands.

== Demographics == The Upper Assam division, comprising 28 percent of Assam's population at 7.69 million, predominantly adheres to Hinduism embraced by nearly 90 percent of its people. More than 90 percent of the people speak Assamese. The major communities of Upper assam are Ahom, Chutia, Tea tribes, Mishing, Sonowal Kacharis, Moran, Matak, Deori, Thengal Kacharis and indigenous Assamese Muslim communities like Gorias Morias and others living here from thousands of years
