Arunachal Pradesh is a state located in the far north eastern part of India, bordering China, and part of which is claimed by China. It has borders with state of Assam to the south and Nagaland to the southeast. Burma/Myanmar lies to the east, Bhutan to the west north, it borders with Chinese-occupied and ruled Tibet. China disputes the border, which is the McMahon Line agreed to by Great Britain and then-de-facto-independent Tibet (but failed to let the then-Chinese government sign, resulting in the dispute) in a 1914 treaty. Itanagar is the capital of the state.

Arunachal Pradesh means "land of the dawn lit mountains" in Sanskrit. It is also known as "land of the rising sun"("pradesh" means "state" or "region") in reference to its position as the easternmost state of India. Most of the people native to and/or living in Arunachal Pradesh are of Tibeto-Burman origin. A large and increasing number of migrants have reached Arunachal Pradesh from many other parts of India, although no reliable population count of the migrant population has been conducted, and percentage estimates of total population accordingly vary widely. Part of the famous Ledo Burma Road, which was a lifeline to China during World War II, passes through the eastern part of the state.

The history of pre-modern Arunachal Pradesh remains shrouded in mystery. It is popularly believed, and may be speculatively assumed, that the first ancestors of most indigenous tribal groups migrated from pre-Buddhist Tibet two or three thousand years ago, if not before, and were joined by Tibetic and Thai-Burmese counterparts later. The earliest written references to Arunachal are popularly believed to be found in the Mahabharata, Ramayana and other Vedic legends. Several characters, such as, King Bhismaka, are believed to represent people from the region in the Mahabharata; however, since corroborating information is unavailable, and since place-names cannot be verified at that historical time-depth, such associations are to a large extent speculative. For example, there is no evidence whatsoever that the name Bhismaka plausibly associates with any indigenous Arunachali tribes or languages at all.

Arunachal Pradesh attracts tourists from many parts of the world. Tourist attractions include the Namdapha tiger project in Changlang district and Sela lake near Bomdila with its bamboo bridges overhanging the river. Religious places of interest include Malinithan in Lekhabali, Rukhmininagar near Roing (the place where Rukmini, Lord Krishna's wife in Hindu mythology, is said to have lived), and Parshuram Kund in Lohit district (which is believed to be the lake where Parshuram washed away his sins). Rafting and trekking are common activities. A visitor's permit from the tourism department is required. Places like Tuting have wonderful, undiscovered scenic beauty.
