immigration from Bangladesh, Nepal and Tibet. There has been influx of vast number of Chakma and Hajong refugees from Bangladesh, which remained a continuous influx till today. Other reasons for high growth rate are migration of labour forces from other neighbouring states and establishment of Government offices, institutions and industries in the District.

The district Headquarter, Changlang and Sub-Divisional Headquarter Jairampur and Miao are declared as urban and whereas, rest of the area of the district are still considered as rural.


Changlang district is home land of fascinating and interesting tribes such as Tangsa, Singpho and Tutsa, and also found Nocte, Lisu (Yobin), Deori and few Adibasi tribes.

The Tangsa tribe is comprise of a number of Sub-Tribes, namely Lungchang, Muklom, Tikhak, Jugli, Mossang, Ronrang, Kimsing, Mungrey, Lungphi, Pongthai, Havi, Sangkey (Sangkeng), Logri, Sangwal, Langching, Hacheng, Yangkuk and Thamphang. They occupy the southeastern hills of the district along Indo-Myanmar border and Namchik basin.

The Singphos occupy the plain foothills area of northern part of the district under Miao, Bordumsa and Diyun circles. Singphos believe themselves to be the descendants of Shapawng Yawng who was first born on this earth. He called himself as Singpho. Shapawng Yawng & rsquo;s son, Tingli Yawang wanted to get the blessings of father and the Mathum Matha, the creator of the world. So he organised the first Manau poi as praising of Gods (Bhikan Gundan Poi). Later, the festival came to be known as Shapawang Yawng Manau Poi in the memory of their ancestor Shapawng Tawng.

Traditionally, Manau dance originated from the birds while they were feasting. The dance was initiated by the human beings under the leadership of Ma Den Yau. In this festival, ethnic dance was performed to the rhythm of the drumbeats traditionally known as ‘Gongs’ and ‘Thongs’. The festival was solemnized for the first time in Miao, Arunachal Pradesh in 1985. Since then it has been celebrated on annual basis by the Singphos of Assam and Arunachal Pradesh which is supported by Shapawng Yawng Manau Poi Festival Celebration Committee. The annual congregation strengthens and upholds their unique culture with the participation of the Singphos residing in different parts of the world.

The Tutsas live in the western part of the district under Changlang and Khimiyong circles. Other tribes and dwellers in district are Nocte, Deori, Adibasi of Bordumsa & Diyun, Lisu (Yobin) & Nepali of Vijoynagar, and Chakma, Hajong and Tibetan came as refugees.

Arts, Culture and Tradition

As far religion is concerned, each tribe has its own traditional religious belief and practices. The Tangsas and Tutsas belief in existence of a supreme being called ‘Rangfrah’. Besides they also believe in a number of deities and spirits. However recently many of them have came under the influence of Christianity and Buddhism. The Singphos are Buddhist by religion but they have not given up their own traditional beliefs of their ancestors as they had adopted the Buddhism as their religion.

The housing pattern of all the tribes and Sub-Tribes are similar. Platform (Machang) types of houses are generally preferred. The floor of the houses are elevated about four to five feet high from the ground. The houses are of single room system with two fire places (Chullas). They cook and sleep in the same room. However, in modern days some people construct house keeping separate provision for fire places and living rooms.

The Tangsas and Singphos have democratic form of social life. They do not have kingship system. All village disputes are settled by the Panchayat i.e. Gaon Buras.

The main occupation of the indigenous people of the district is agriculture and allied activities. They also rear domestic animals like Cattle, Pig, Goats and Poultry birds.

The most of the indigenous population lives in the villages. They are living through farming and allied activities such as government jobs, agricultural labourer, government contract works, casual workers under government departments, trade in local products etc. There is no direct interference in preservation of traditional customs. But with the spread of education and socio-economic development, aged old traditional customs and economic pattern of the inhabitants are changing gradually. Today, one can see many tribal youths particularly educated group instead of working in agricultural have switched over to business deals, contract works, government jobs and others, which offer them good income. However, majority of the population are living hand to mouth particularly in the interior areas where road communication and other developments have not yet reached.

Moh-Mol: Moh-Mol is basically agricultural related festival of Tangsas, which signifies end of an agricultural activity or beginning of crop season. Since life and activity of tribal people revolve around agriculture, they adhere to utmost important to this festival. It is a gala of pomp and show of traditional colourful costumes, ornaments, art and crafts that enriched the pride of Tangsa’s cultural heritage of the past. It therefore inspires younger generation every year to inherit, protect, preserve and continue it to the later generations further.

While some community of Tangsas observe it for beginning of agriculture activity in the field, some do it for sowing of paddy, and some other for welcoming new crop into home. That is why celebration is performed with religious fervor and devotion. People chant mantras for good harvest of their crops, prosperity of their live stocks and wealth, and disease free live of their family or village community to enjoy food and drinks year after year. So, the offerings, sacrifices, food, drinks, folk-songs and dances accompanied by rhythmic music of drum beats and gong reverberations highlight the festival.

As time of particular agriculture activity differ from village to village, time of their festival also vary accordingly. It is observed generally between April and July, but village community in the council as per their convenience decides exact date.

As Tangsas have no definite date to mark the New Year, the Moh-Mol festival is considered to be the end and beginning of the calendar. People of all ages, on this occasion, sing and dance with their best presentation in colorful attire. In a sense, they do it in order to shake off the shackles of old painful memories and fatigues, and to recharge their energy and enthusiasm, preparing to face reality of life in waiting.

This is also a wonderful occasion for people to exchange goodies, love and affection with their near and dear ones, especially, relatives who visit from distant villages or places. Bogged down by daily chores of their households, people usually look for “Moh/Mol” occasion to see those distant relatives.

“Moh/Mol” is also a forum for development of new friends and acquaintances. Many strangers come into contact on this day, and it may become a permanent relationship. Especially, it is common among young boys and girls who may knot their relation to grow into life time partner.

Some communities of Tangsa, on Moh-Mol eve or during, bid ritual farewell to departed soul of the family, if any member expired during the year. They believe deceased soul dwells in the family who needs farewell by offering foods and drinks for his/her peaceful rest in the ancestor realm.

Then there are prayer “ROM-ROM” to Godess of Crops “Tungaja Chamja” for blessing of bumper harvest, Godess of Prosperity for gain of wealth and “NONG” for longevity of the Nong Culture. All walks of people, irrespective of sex and age, lay down their hearts in enjoying food, drinks, songs, dances and music that filled the air of the ground with maddening effect.

However, with the passage of time, dedication, spirit and traditional costumes are seen continuously undergoing mark changes. The sensitive youths are, therefore, seriously concern over this fading and ever degenerating trend of traditional culture and colours of the society. They feel that it is high time for the society especially the youths to dedicate and mobilize resources for protection, preservation and propagation of tradition and culture for the future generations.

River Systems

Namdapha River Deban

Namdapha River

The major Rivers are Noa-Dehing, Namchik and Tirap. Other Rivers are Namphuk, Dapha, Namphai,

Rima, Tissu, Tarit, Tara, Tikeng, and Tiging. Most of the rivers after winding through the hills and valleys come down to the plains and join Buri-Dihing River. The Noa-Dihing River, which originates from Patkai Range flows east to west through the entire northeastern and northern stretch of the District. The Tirap rises from a high peak between Laju and Wakka and flows Southwest to Northeast passing through the Changlang town ultimately meet Buri-Dihing near Lekhapani in Assam. These rivers become turbulent during the monsoon and cause a great damage to agriculture fields in the area but at the same time increases the fertility of the soil by depositing silt along their courses.
