A river of gold flows through this exotic land of dawn-lit mountains and that's only the beginning of the story. Mysterious, powerful and beautiful, with faces and moods that change dramatically ever so often, rivers with distinctive individualities form the colorful lifelines of Arunachal Pradesh-the land kissed by the first rays of the sun. Arunachal Pradesh, earlier known as Northeast Frontier Agency, and largest of the seven sisters of North East India, shares international boundaries with Bhutan, Tibet, China and Myanmar and state boundaries with Assam and Nagaland.
Arunachal Pradesh stretches on the Northeast frontier of India from the foothills of the eastern Himalayas to their peaks. The state extends latitudes 26.42°N-29.30°N and longitudes 90.36°E- 97.30°E. One of the landlocked states of India, Arunachal Pradesh shares its border in the east with Myanmar, Bhutan in the west, China in the north, and Assam in the south.
There is not much information available on the history of Arunachal Pradesh. The earliest recorded history dates back to 16th century AD when Ahom rulers of Assam extended their kingdom to this region. The Ahom rulers had a tradition of not interfering in the affairs of the tribes of this region. The British continued this policy, and in 1873, they banned entry of outsiders to this region. The Government of India continued this policy until 1962, when China attacked this region. After 1962, steps were taken to counter future border disputes with China, and roads, electricity, modern democratic institutions, and cash economy were introduced here.
Before 1962, the state was known as Northeast Frontier Agency and was constitutionally a part of Assam. Because of its strategic importance, it was administered by the Ministry of External Affairs until 1965 and subsequently by the Ministry of Home Affairs through the governor of Assam. In 1972, Arunachal Pradesh was constituted as a union territory, and, in 1987, it became the 24th state of the Indian Union.
