Tibetan Buddhism got a strong foothold among the tribal groups as early as in the 7th century, where the Kachen Lama constructed the Lhagyala Gompa in Morshing.Upon the arrival of the British, the present-day West Kameng was placed under what was known as the North-East Frontier Agency (later, Arunachal Pradesh).It comprises all the regions inhabited by the Miji community[2] West Kameng district occupies an area of 7,442 square kilometres (2,873 sq mi),[3] comparatively equivalent to Papua New Guinea's New Ireland.[9] Like most of Arunachal Pradesh, Jhum, or shifting cultivation, is practised among the tribes who live in lower elevations where there is a temperate or subtropical climate.There are 4 Arunachal Pradesh Legislative Assembly constituencies located in this district: Dirang, Kalaktang, Thrizino-Buragaon and Bomdila.[10] According to the 2011 census West Kameng district has a population of 83,947,[12] roughly equal to the nation of Antigua and Barbuda.Languages of West Kameng (2011)[14] Most of the inhabitants are Buddhist, though the Aka, Bugun (Khowa), and Miji have indigenous religions and those tribe members follow a mix of Buddhism, Hinduism, and Donyi-Polo (a form of Animism).
