I had the opportunity of travelling in Nagaland as a part of my work last year. I spent a few weeks in Tuensang district.
Located at the northeastern corner of the state of Nagaland the Tuensang district shares 159 kilometers long border with Myanmar (Burma) in the east, Mon district in the north, Assam in the northwest, Mokokchung and Zunheboto districts in the west and Phek district in the south. Tuensang was a part of the area earlier known as North-East Frontier Agency (NEFA). In 1957 Tuensang division of the then NEFA became a district as one of the then three districts of the state viz. Kohima, Mokokchung and Tuensang. In December 1963 the district of Nagaland was divided into seven districts in place of three. Tuensang district had an area of 4,228 sq. km until recently, the district has been further divided into two districts visibly Kiphire district and Longleng district since January 24th 2004.
I will post later about the tribes of Nagaland and some of my travel experiences there.
