Tripura is a state in Northeast India.there have been suggestions to the effect that "the origin of the name Tripura is doubtful", raising the possibility that the Sanskritic form is just due to a folk etymology of a Tibeto-Burman (Kokborok) name. Variants of the name include Tripra, Tuipura and Tippera.
The Indian epic, the Mahabharata; ancient religious texts, the Puranas; and the Edicts of Ashoka – stone pillar inscriptions of the emperor Ashoka dating from the third century BCE – all mention Tripura.The boundaries of the kingdom changed over the centuries. At various times, the borders reached south to the jungles of the Sundarbans on the Bay of Bengal; east to Burma; and north to the boundary of the Kamarupa kingdom in Assam. There were several Muslim invasions of the region from the 13th century onward, which culminated in Mughal dominance of the plains of the kingdom in 1733, although their rule never extended to the hill regions. The Mughals had influence over the appointment of the Tripuri kings.Tripura became a princely state during British rule in India.Following the independence of India in 1947, Tippera district – the estate in the plains of British India – became a part of East Pakistan, and Hill Tippera remained under a regency council until 1949. The Maharani Regent of Tripura signed the Tripura Merger Agreement on 9 September 1949, as a result of which Tripura became a Part C state of India.
