Arunachal Pradesh /ˌɑːrəˌnɑːtʃəl prəˈdɛʃ/ is one of the twenty-nine states of India. Located in northeast India, it holds the most north-eastern position among the states in the north-east region of India. Arunachal Pradesh borders the states of Assam and Nagaland to the south, and shares international borders with Bhutan in the west, Myanmar in the east and China in the north. Itanagar is the capital of the state. Arunachal Pradesh has territorial disputes with both the PRC and ROC due to its cultural, ethnic and geographic proximity to Tibet.
A major part of the state, formerly called the North-East Frontier Agency, is disputed by China as the legality of the Simla Accord is not recognized by it. China claims most of the state as South Tibet. The state is seen to have major potential for hydropower development.
Arunachal Pradesh, whose name means Land of the Dawn-Lit Mountains in Sanskrit, is also known as the Orchid State of India or the Paradise of the Botanists. Geographically, it is the largest among the North-east Indian states commonly known as the Seven Sister States. As in other parts of Northeast India, the people native to the state trace their origins to the Tibeto-Burman people. In recent times, large number of migrants from various parts of India and other lands have built extensive economic and cultural ties with the state's population.
No reliable population count of the migrant population exists, and the percentage estimating the total actual population accordingly, vary. Arunachal Pradesh has the highest number of regional languages in the Indian subcontinent, enriched with diverse culture and traditions.
