Tripura is a state in North-East India which borders Bangladesh, Mizoram and Assam. It is surrounded by Bangladesh on its north, south and west: the length of its international border is 856 km (84 per cent of its total border). It shares a 53 km long border with Assam and a 109 km long border with Mizoram. The state is connected with the rest of India by only one road (NH-44) that runs through the hills to the border of Karimganj District in Assam and then winds through the states of Meghalaya, Assam and North Bengal to Calcutta.
There is a common belief that the name of the State has originated from "Tripura Sundari" - the presiding deity of the land which is famous as one of the “51 Pithas” of Hindu Pilgrims. Apart from this traditional view, it is also believed that the land was originally known as "Tuipra" meaning a land adjoining the water. It is a fact that in the early days, the boundaries of Tripura extended up to the Bay of Bengal when its rulers held sway from Garo hills to Arakan.
