Arunachal Pradesh

Arunachal Pradesh is a state in Northeastern India. It was formed from the erstwhile North-East Frontier Agency (NEFA) region, and became a state on 20 February 1987. Itanagar is the state capital.

Arunachal Pradesh is the largest of the Seven Sister States of Northeast India by area. It borders the states of Assam and Nagaland to the south. It shares international borders with Bhutan in the west, Myanmar in the east, and a disputed 1,129 km border with China's Tibet Autonomous Region in the north at the McMahon Line.

As of the 2011 Census of India, Arunachal Pradesh has a population of 1,382,611 and an area of 83,743 square kilometres (32,333 sq mi). It is an ethnically diverse state, with predominantly Monpa people in the west, Tani people in the centre, Mishmi and Tai people in the east, and Naga people in the southeast of the state. About 26 major tribes and 100 sub-tribes live in the state,[citation needed] including Adi, Nyshi, Singpho, Galo, Tagin and Apatani. The Mishmi tribe has three sub-tribes, namely Idu-Mishmi, Digaru-Mishmi and Miju-Mishmi.

A major part of the state is claimed by the former Republic of China (as part of Tibet Area) and People's Republic of China (Tibet Autonomous Region), which refers to it as "Zangnan," (lit. "South Tibet"). The People's Liberation Army briefly occupied parts of the state in 1962.
