Tripura is a state in Northeast India. The third-smallest state in the country, it covers 10,491 km2 (4,051 sq mi) and is bordered by Bangladesh (East Bengal) 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. Indigenous communities, known in India as scheduled tribes, form about 30 per cent of Tripura's population. The Kokborok speaking Tripuri people are the major group among 19 tribes and many subtribes. The Bengali people form the ethno-linguistic majority in Tripura.
The area of modern Tripura was ruled for several centuries by the Tripuri dynasty. It was the independent princely state of the Tripuri Kingdom under the protectorate of the British Empire which was known as Hill Tippera while the area annexed and ruled directly by British India was known as Tippera District (present Comilla District). The independent Tripuri Kingdom (or Hill Tippera) joined the newly independent India in 1949. Ethnic strife between the Tripuri people and Bengali population
led to tension and scattered violence since its integration into the
country of India, but the establishment of an autonomous tribal
administrative agency and other strategies have led to peace.
