Dima Hasao district (IPA: [ˈdɪmə həˈsaʊ]), earlier called North Cachar Hills district, is an administrative district in the state of Assam, India. As of 2011, it is the least populous district of Assam.[1] [2]

Dima Hasao district is one of the two autonomous hill districts of the state of Assam. The district headquarters Haflong is the only hill station in Assam, a tourist destination, also nicknamed the Switzerland of the north-east.


"Dima Hasao" means "Dimasa Hills" in the Dimasa language.


The earliest inhabitants of the present district were Mongoloid groups who preferred hilly terrain and practised their own culture, tradition and land rights, governing themselves as independent tribes. As per records of different British historians and officials, North Cachar Hills was already occupied by the Dimasa Kacharis, erstwhile old Kuki tribes viz. Biate, Hrangkhol, Hmar, Sakachep and Zeme Naga tribes, during the British Rule in India.[3]

Medieval period

During the medieval period (1500–1854), Dima Hasao was part of the Dimasa Kachari Kingdom called the "Cachar Kingdom", with its capital at Maibang. The Dimasa Kingdom as per Ahom Buranji, stretched from the Kallang river in Nagaon to the Kapili river.[4] This includes parts of Cachar and North Cachar (Dima Hasao), the districts of Hojai, Nagaon, Golaghat and Karbi Anglong of Assam and Dimapur district, in Nagaland.

Colonial period

Raja Govinda Chandra Hasnu
Raja Govinda Chandra Hasnu

In the colonial period, Khaspur in present-day Cachar district was the administrative centre. However an internal schism led to the division of the old Cachar Kingdom into North Kachar and South Kachar. The last Dimasa king, Govinda Chandra Hasnusa, assigned Kashi Chandra the hilly tract of Cachar i.e. roughly Dima Hasao (North Kachar Kingdom), for administrative purposes. Soon the latter declared its independence over the hilly portion. That led to the treacherous murder of Kashi Chandra by Raja Govinda Chandra Hasnusa.[citation needed] Incensed, the son of Kashi Chandra, Tularam, incessantly created political turbulence, asserting his sovereignty over hilly portion of Cachar Kingdom. Finally, with British assistance, Tularam succeeded in carving North Cachar Hills from Cachar Kingdom. David Scott, agent to the British Raj in 1829[5] made an arrangement to recognise Tularam as the ruler of North Cachar (Dima Hasao). In 1850s, Tularam died and the frequent Angami raids and a grave incident at Semkhor village paved the ground to extend British influence over North Cachar. In 1853, North Cachar was annexed and made part of the Nagaon district of British Assam as a subdivision.

In 1867, this sub-division was abolished and apportioned into three parts among the Cachar, Khasi and Jaintia Hills districts, and Nagaon. The present Dima Hasao district, or formerly North Cachar Hills district was included in the old Cachar district, with Asalu being only police outpost. In 1880, this portion was constituted into a sub-division with headquarters at Gunjung under Cachar district.

This headquarters was shifted to Haflong in 1895. Since then, Haflong has continued to be the headquarters. In 1951, after the adoption of the Indian constitution, North Cachar Hills ceased to be a part of Cachar district, as specified under paragraph 20 of the sixth schedule to the constitution. This part, along with Mikir Hills, constituted a new civil district named "United District of North Cachar and Mikir Hills", which went into effect on 17 November 1951. According to a provision of the sixth schedule, two different councils were later constituted, viz., North Cachar Hills District Council and Mikir Hills District Council. Within those geographical boundaries, North Cachar Hills District Council was inaugurated on 19 April 1952.

Since Independence

On 17 November 1951, Mikir Hills and North Cachar Hills District was created with area occupying present Dima Hasao district, Karbi Anglong and West Karbi Anglong district. On 2 February 1970, the government declared an independent administrative district, viz., North Cachar Hills District with the geographical boundary of autonomous North Cachar Hills district council. At present,[when?] this autonomous council possesses administrative control over almost all departments of the district except Law and Order, Administration, and Treasury department.


Dima Hasao comprises three subdivisions: (I) Haflong, (II) Maibang and (III) Diyungbra. The district consists of five Community Development Blocks: (I) Jatinga Valley Development Block, Mahur; (II) Diyung Valley Development Block, Maibang; (III) Harangajao ITD Block, Harangajao; (IV) Diyungbra ITD Block, Diyungmukh; and (V) New Sangbar Development Block, Sangbar.[6] There is one municipality board viz. Haflong and three town committees in Dima Hasao viz. Mahur, Maibang and Umrangso and also mini-towns like Harangajao, Langting and Diyungbra.


The district headquarters are located at Haflong. Dima Hasao district occupies an area of 4,888 square kilometres (1,887 sq mi).,[7] comparable to Brazil's Ilha Grande do Gurupá.[8] It is the second-largest district of Assam after Karbi Anglong. Dima Hasao District is surrounded by Karbi Anglong district and Nagaland on the northeast, Manipur on the east, Hojai District to the north, West Karbi Anglong district on the northwest, Meghalaya on the west and Cachar district in the south.
