The Tripuras are one of the indigenous peoples living both in the plains and the Chittagong Hill Tracts in Bangladesh. During the partition of the Indian subcontinent, the princely state of Tripura were merged neither into India nor Pakistan. However, Tripura Kingdom was merged in 1949 with India through a merger agreement. The peoples of Tripura, both in Bangladesh and the Indian State of Tripura, shared common culture, history, tradition, and way of life. Their languages are called Kokborok, of which there are more than one million speakers. Tripura's main festival is boishu.
