Tripura () is a state in northeastern India. The third-smallest state in the country, it covers 10,491.69 km2 (4,050.86 sq mi) and is bordered by Bangladesh to the north, south, and west, and the Indian states of Assam and Mizoram to the east. In 2011 the state had 3,671,032 residents, constituting 0.3% of the country's population.The area of modern Tripura — ruled for several centuries by the Manikya Dynasty — was part of an independent princely state under the protectorate of the British Empire. The independent Tripuri Kingdom (also known as Hill Tippera) joined the newly independent India in 1949.
Tripura lies in a geographically isolated location in India, as only one major highway, National Highway 8, connects it with the rest of the country. Five mountain ranges — Hathai Kotor, Atharamura, Longtharai, Shakhan and Jampui Hills — run north to south, with intervening valleys; Agartala, the capital, is located on a plain to the west.
