Kokrajhar District Museum was declared as a District Museum in 1986. The foundation stone was laid by the then Hon’ble Chief Minister of Assam Lt. Hiteswar Saikia in the presence of Sri Mukut Sharma, the then Minister of Education, Assam, Sri Luis Islary then Minister of state Education, Late Ranen Basumatary, Ex- Minister of Assam, Sri Mohini Mohan Brahma, a respected citizen of Kokrajhar and many others were also present on the occasion.
In the early days, the District Museum was functioning at a rented house with only a work charge employee as its care taker. Later Sri Arun Ch. Bargayary, a very enthusiastic assistant teacher of a local H.S. school was entrusted with the task of collection of Museum objects. Later on the posts of the Museum workers were sanctioned by the Government and then the Museum started to function in full movtivation. Mr. Jiten Shyam was the first Officer-in-charge of the sanctioned post of District Museum, Kokrajhar. He was followed by Mrs. Kabita Devi. Sri Sunil Kr. Goswami, Lt Gautom Bordoloi, Smt Banani Deka, Sri Suresh Ch. Kalita and now Smt. Supriya Brahma. Sri Suresh Ch. Kalita rendered his service to the District Museum, Kokrajhar for the longest period of his service life.
During his period itself, the department of Museum under BTAD was transferred to the administration of BTC combined with Department of Archaeology. So the Department of Museum has become under Museum & Archaeology Department in BTC. A new building was set up at Bhabanipur, Titaguri about 2 (two) km away from Kokrajhar town. A beautiful round shaped building for District Musuem cum C.H.D. (Council Head of Department) office is established under the administration of Bodoland Territorial Council. The office is now functioning only with 5 (Five) number of employees viz C.H.D. cum District Museum Officer assisted by a Junior Assistant, a Peon, a Chowkider & a Night Chowkider.
The District Museum, Kokrajhar is rich with the ethnographic objects of Boro, Garo, Rabha and Santhals. In collection of those objects we always should remember the name of Sri Mohini Mohan Brahma, a respected resident of Kokrajhar town who was very interested and put his all effort to make the treasure of Kokrajhar Museum. Now many of the collections are transferred to the Assam State Museum for Preservation. When we talk about the objects displayed in District Museum, Kokrajhar, we can never forget the name of Arun Ch. Bargayary and Sri Sibananda Sarma whose effort and initiative are the physical outcome of the District Museum, Kokrajhar. Now the Museum is rich with more than 200 (Two hundred) objects of diverse categories.
