Tripura () is a state in northeastern India. The third-smallest state in the country, it covers 10,491 km (4,051 sq mi); and the seventh-least populous state with a population of 3.67 million. It is bordered by Assam and Mizoram to the east, and by Bangladesh to the north, south and west. Tripura is divided into 8 districts and 23 sub-divisions, where Agartala is the capital and the largest city in the state. Tripura has 19 different tribal communities with a majority Bengali population. Bengali, Kokborok, and English are the state's official languages.
The area of modern Tripura — ruled for several centuries by the Manikya Dynasty — was part of the Tripuri Kingdom (also known as Hill Tippera). It became a princely state under the British Raj during its tenure, and acceded to independent India in 1947. It merged with India in 1949 and was designated as a 'Part C State' (union territory). It became a full-fledged state of India in 1972.
