Arunachal Pradesh is India 's land of the rising sun. Situated on the easternmost tip of the country, it shares its international border with Bhutan , China and Burma , and its national border with Assam and Nagaland. The territory is divided into 10 districts. This land, blessed with the most breathtaking scenery, an amazing variety of wildlife, magnificent ancient ruins and charming tribal folk, is any traveller's paradise.

In 1826 the British exercised their control in Assam after the treaty of Yandaboo concluded on 24th February 1826 . Before 1962 the Arunachal was popularly called North Eastern Frontier Agency and was constitutionally a part of Assam . 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 January 20,1972 , it was constituted as a Union Territory and renamed Arunachal Pradesh. Arunachal has become full-fledged State on February 20, 1987 . Till 1972, it was known as the North- East Frontier Agency (NEFA)

The first ancestors of the tribal groups migrated from Tibet during the pre-historic period, they were joined by Thai-Burmese counterparts later. Except for the northwestern parts of the state, little is known about the history of Arunachal Pradesh, although the Apatani tribe had legendary knowledge of the history. Recorded history was only available in the Ahom chronicles during the 16th century. The tribal Monpa and Sherdukpen do keep historical records of the existence of local chiefdoms in the northwest as well. Northwestern parts of this area came under the control of the Monpa kingdom of Monyul , which flourished between 500 B.C. and 600 A.D. This region then came under the loose control of Tibet and Bhutan , especially in the Northern areas. The remaining parts of the state, especially those bordering Myanmar , came under the control of the Ahom and the Assamese until the annexation of India by the British in 1858.

Recent excavations of ruins of Hindu temples such as the 14th Malinithan at the foot of the Siang hills in West Siang shed new light on the ancient history of Arunachal Pradesh. Paintings of the Hindu gods and altars remained untouched for many years. They attracted many local pilgrims. Another notable heritage site, Bhismaknagar, suggested that the Idu Mishmi had a local civilisation. The third heritage site, the 400-year-old Tawang monastery in the Tawang district also provides historical evidence of the Buddhist tribal peoples.
