The term "Naga" refers to the Naga people, who were called "Naga" or "Naka" in the Burmese language, meaning "people with pierced ears".History
In British India, the major part of the hills came under the Naga Hills District. A part of the Naga Hills under the British India control was coalesced into a district in 1866. The boundaries of the Naga Hills District were gradually expanded by annexation of the territories of several Naga tribes, including the Aos, the Semas and the Konyaks. In 1912, the district was made part of Assam province. Following the Partition of India, it was merged with the Tuensang Division to create the state called Nagaland in 1963.Geology: national geological monument
