State (pop., 2008 est.: 2,187,000), northeastern India. It borders Myanmar (Burma) and the states of Manipur, Assam, and Arunachal Pradesh and has an area of 6,401 sq mi (16,579 sq km). Its capital is Kohima. Except for a small area of plain, the entire state is covered with ranges of hills that are northward extensions of the Arakan Mountains system. Myanmar ruled the region from 1819 to 1826, when the British began annexing its hill areas. The Naga people accepted statehood within an independent India in 1963. There are more than 20 major Naga tribes and subtribes, with different dialects and customs. About two-thirds are Christian, and most others are Hindu or Muslim. Agriculture is the mainstay of the economy. Crops include rice, millet, sugarcane, potatoes, and tobacco.
