Manipur is a state in northeastern India with Imphal as its capital. It borders the Indian states of Assam to the west, Mizoram to the south, and Nagaland to the north and shares the international border with Myanmar, specifically the Sagaing Region to the east and Chin State to the southeast. Covering an area of 22,330 square kilometers (8,621 mi²), the state consists mostly of hilly terrain with the 1813-square-kilometre (700 mi²) Imphal Valley inhabited by the Meitei (Manipuri) community, historically a kingdom. Surrounding hills are home to Naga and Kuki-Zo communities, who speak Tibeto-Burman languages. The official language and lingua franca, Meitei (Manipuri), also belongs to the Tibeto-Burman family.
