Tripura is situated southeast of Bangladesh and is located between the parallels of 22056” and 24032” North latitudes and 91021” east longitudes. The present Tripura state

The Tripuri people have a rich historical, social and cultural heritage which is totally distinct from that of the mainland Indians, their distinctive culture as reflected in their dance, music, festivals, management of community affairs, dress and food habit has a strong Mongoloid Base. Kok Borok, the linguafranca of the twelve largest linguistic groups of the indigenous Tripuris and other dialects spoken in Trpura are of the Tibeto-Burman group as distinct from those spoken in India. There is no influence whatsoever of from those spoken by other Mongoloid peoples in the North-eastern region.
Tripura’s basic problem, rather the indigenous Tripuri peoples’ problem, is the huge influx of foreigners, mainly Hindu Bengalis and the resultant alienation of indigenous land thereby causing the threat to the distinctive identity of the Tripuri people and their very existence. India has all along been encouraging this influx of co-religionists and co-ethnic population so as to induct a co-ethnic population base to serve her security interests. The huge influx of foreigners has completely upset the demographic composition of Tripura. The indigenous Tripuri people which constituted more than 85% of the total population at the time of annexation by India has now been reduced to an insignificant minority of less than 29% of the present total of 3 million. To the indigenous, the urban areas have already become a foreign land where their presence is hardly 5%. This population invasion has become the gravest threat to the very existence of the small indigenous Tripuri people as a distinct human groups.
