Arunachal Pradesh is the north-eastern state of India, and it is believed that the state existed from the prehistoric days of Ramayana, Mahabharata, and other sacred legends. It is written and believed that Lord Parashuram, King Bhismaka, and Princess Rukmini belong to Arunachal Pradesh. As per records, it is believed that the state can be found in the Ahom Chronicles, which comes from the 16th Century. Arunachal Pradesh has seen several rulers and reigns rise and fall, yet it remains calm and pious.
From 500 BC and 600 AD, Arunachal Pradesh was ruled by the Monpa Kingdom. After this period, the northern area was ruled by Bhutan and Tibet, and the other parts were under the reign of Ahom and Assamese until the British annexation occurred in 1858. At that time, there were majorly Tibeto-Burmese origin people there. Monpas, Bangians, and Dallas were there as majority tribes. The history of Arunachal Pradesh has a distinct charm that attracts the tourists. There are remains of temples here from the 14th Century that tell so many tales.
The relationship between Arunachal with Tibet has been for centuries and is proved by the Tawang Monastery, which lies towards the northwest of Arunachal Pradesh. The monastery is 400 years old. Earlier the state was called North Eastern Frontier Agency (NEFA), and it was constitutionally a part of Assam.
The Simla Accord, a treaty in the country, was negotiated by the representatives of Tibet, China, and Britain between 1913 and 1914. China did not accept the borderline. After that, a map was published that showed the official boundary between India and Tibet.
After getting independence, China declared victory in the year 1962, and thus the nation had to withdraw from the borderline and get the prisoners of war back. Until 1965, the External Affairs Ministry and the Home Affairs Minister administered NEFA. The Union Territory of Arunachal Pradesh was renamed Arunachal Pradesh in 1972. Then in 1987, Arunachal Pradesh became the 24th state of the Indian Union. In 2007 the Government Of Arunachal Pradesh decided to start the barter trade with Tibet, which was closed after the Sino-Indian war of 1962.
