It is said that the existing zila headquarters is situated on the bank of the chengi stream(chhara) which was full of Catkin plants means ‘Khagra’ in local languages. This might be the origin of the zila name as Khagrachhari.

Administration: Khagrachhari subdivision was turned into a zila in 1983. The zila of Chittagong Hill Tracts was established in 1860 under the 'Frontier Tribes Act 22 of 1860'. Following the zila of Chittagong Hill Tract Regulation Act the Chittagong Hill Tract was divided into three subdivisions (included Khagracharri) in 1900. The Khagrachhari Local Government Legislative Council was formed in 1989 (in accordance with the Khagrachhari Hill Zilas Council, Act 20), which, on the basis of the historic 'Chittagong Hill Tracts Peace Accord', was turned into Khagrachhari Hill Zila Council on 2 December, 1997. The zila consists of 8 upazilas, 38 unions, 120 mauzas, 1702 villages, 3 paurashavas, 27 wards and 154 mahallas. The Upazilas are DIGHINALA, KHAGRACHHARI SADAR, LAKSHMICHHARI, MAHALCHHARI, MANIKCHHARI, MATIRANGA, PANCHHARI and RAMGARH.

Historical Events: The Chittagong Hill Tracts was under the reign of the Tripura State, the Arakans and the Sultans in different times before it came under the control of the British East India Company in 1760. Although the British got the authority of the Chittagong Hill Tracts in 1760, they had no authority besides collecting nominal taxes. Until 1860, two kings or chiefs governed the internal administration of this region. In 1860, another 'circle' was formed in present Khagrachhari zila, inhabited by the Tripura population. The chief or the Raja of this circle was selected from the minority Marma population. The 'circle' was named after the Tripura dialect the 'Mun Circle', but later, the 'Mun dialect', was changed and renamed as 'Mong Circle'. In 1900 the British offered independent status to Chittagong Hill Tracts recognising the culture and language of the hill tracts population. But during the Pakistan period this status was abolished, which created anger among the hill population. Moreover, due to the construction of the Kaptai dam in 1960, thousands of people became homeless and refugee. At this perspective the hill population revolted claiming autonomy. Through the Chittagong Hill Tracts peace Accord on 2 December 1997 this problem was resolved.
