Arunachal Pradesh also called as “Land of the Rising Sun” is one of the twenty-nine states of India, located in northeast India.
Neolithic tools found in Arunachal Pradesh indicate that people have been living here for at least eleven thousand years.The earliest inhabitants of Arunachal Pradesh were the people from Indus Valley Civilisation. The history of pre-modern Arunachal Pradesh is unclear. Oral histories possessed to this day by many Arunachali tribes of Tibeto-Burman stock are much richer and point unambiguously to a northern origin in modern-day Tibet.According to the Arunachal Pradesh government, the Hindu texts Kalika Purana and Mahabharata mention the region as the Prabhu Mountains of the Puranas, and where sage Parashuram washed away sins, the sage Vyasa meditated, King Bhishmaka founded his kingdom, and Lord Krishna married his consort Rukmini.In 1913–1914 representatives of China, Tibet and Britain met in India ending with the Simla Accord.British administrator, Sir Henry McMahon, drew up the 550 miles (890 km) McMahon Line as the border between British India and Outer Tibet during the Simla Conference. But the conference was not that successful. In 1938 the Survey of India published a detailed map showing Tawang as part of North-East Frontier Agency. In 1944 Britain established administrations in the area from Dirang Dzong in the west to Walong in the east. Tibet altered its position on the McMahon Line in late 1947 when the Tibetan government wrote a note presented to the newly independent Indian Ministry of External Affairs laying claims to Tawang south of the McMahon Line. In 1947, India unilaterally declared that the McMahon Line is the boundary.
