Northeast India
group of Northeastern Indian states
Northeast India, officially the North Eastern Region (NER), is the easternmost region of India representing both a geographic and political administrative division of the country. It comprises eight states: Arunachal Pradesh, Assam, Manipur, Meghalaya, Mizoram, Nagaland, and Tripura (commonly known as the "Seven Sisters"), and the state of Sikkim. North-east India is one of the most linguistically diverse regions in the world.
The region has India's international border of 5,182 kilometres (3,220 mi) with five neighbouring countries: China to the north, Myanmar to the east, Bangladesh to the southwest, Nepal to the west, and Bhutan to the northwest. It comprises an area of 262,184 square kilometres (101,230 sq mi), almost 8 per cent of that of India and has a population of 45,772,188, almost 4 per cent that of India. The Siliguri Corridor connects the region to other parts of India.
Northeast India is very rich in mineral wealth; India's first oil well was dug in Northeast India in 1865, in Digboi in Assam. The region houses one of the notable ophiolites in the world.
The region has been highly strategic and it witnessed one of the fiercest battles in the Second World War, the Battle of Imphal and Kohima (1944) where the Japanese Forces and the Allied Forces were engaged in a pitched battle that saw thousands of casualties on both sides.
The states of North Eastern Region are officially recognised under the North Eastern Council (NEC), constituted in 1971 as the acting agency for the development of the north eastern states.

Why this record matters
The phrase “group of Northeastern Indian states” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Sep 11, 2026. The linked authority identifier is Q863038. VIAF identifies the subject as 173797985. The Library of Congress control number is sh85064956. Authority coordinates are 26.000, 92.700. None of the 3 selected statements returned an explicit reference. The first chronological checks are 1865, 1944 and 1971.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
