The biggest district in the Indian state of Nagaland is the district of Tuensang. It is located in the extreme eastern corner of the state. Tuensang is the administrative headquarters of the district. It shares an international boundary with the country of Myanmar. In order to govern over the then existing North Eastern Frontier Agency, the establishment of this town occurred in the year of 1947. The North Eastern Frontier Agency was made up of the currently existing regions of Tuensang, Mon, Longleng and Kiphire Districts. In the present time, the region of Eastern Nagaland comprises of these four numbers of districts.
1,371 meters above the sea level is the elevation of this place. The district shares its boundaries on the north-eastern side with the district of Mon, on the northern side with Longleng, on the western side with the districts of Mokokchung and Zunheboto and on the southern side with Kiphire. It also has an international boundary with the country of Myanmar on the eastern façade. Mount Saramati, which is the most altitudinous peak of the state, is situated in the district of Tuensang. The names of the principal rivers of the district are Dikhu and Tizu.
The current day region of Tuensang was a huge expanse of land situated in between Assam and Burma till the starting part of the 20th century. Throughout this period of time, each of the villages in this territory was a self-governing body. The village used to have clashes with each other. They were engaged in frequent battles with each other. Sometimes, these battles took place in the areas, which were under the control of British forces. The governed villages were attacked and destructed by the un-governed villages. Consequently, actions had to be taken against the villages by the British forces, who had taken wrongful actions. The British send forces to these villages in the ungoverned areas.
On 12th January of the year 1889, the very initial disciplinary group was sent to Tuensang. The British forces triumphed over these ungoverned villages, although these villages fought back fiercely most of the times. The villages were scorched down as a penalty and the security was forced on them. During this time, the British Government did not bring these areas under the control. However with the starting of the 20th century, these regions, along with other territories of the Naga Hills, were taken under their control and administration. The expansion of the Assam Frontier Tract Regulation of 1880 was done to the Hills by the year of 1914 with the initiation of the Foreign and Political Department of Government. After taking these regions under their control, the name of ‘North East Frontier Tract’ was given to them. Thus, the current day district of Tuensang was also included in their administered areas; however, in reality these areas were not governed properly till the year of 1948.
