Home to one of the last uncontacted peoples on Earth
North Sentinel Island
A small island in the Bay of Bengal is off limits to the entire world by law, protecting the Sentinelese, a tribe that has resisted outside contact for tens of thousands of years.
North Sentinel Island, part of India's Andaman Islands in the Bay of Bengal, is home to the Sentinelese, believed to be one of the last people on Earth who have had virtually no contact with outside civilization. Estimates put their population between 50 and 200 people, and they have violently repelled nearly every attempt at outside contact for centuries, including a fatal encounter in 2018 when an American missionary who illegally traveled to the island was killed by residents shortly after landing. The Sentinelese are thought to be descendants of some of the earliest human migrations out of Africa, potentially preserving a lineage isolated for tens of thousands of years. Because the tribe has no immunity to common outside diseases, and firmly rejects contact anyway, the Indian government has made it illegal to approach within several nautical miles of the island, enforcing an exclusion zone by law rather than simply by tribal hostility. Almost nothing is known about their language, beliefs, or society, since virtually no anthropologist has ever been able to safely observe them up close, making North Sentinel one of the true blank spots left on the modern map.
Tens of thousands of years of isolation
Genetic and anthropological evidence suggests the Sentinelese are descended from some of the earliest human populations to leave Africa and settle South Asia, possibly 50,000 years ago or more, and that they have remained isolated from other Andamanese groups and outside contact for most of that time. Their language is unrelated to any known language, and even neighboring Andamanese peoples cannot communicate with them, indicating an extraordinarily long period of separation.
A history of resisting contact
The Sentinelese have repelled nearly every documented approach since British colonial explorer Maurice Vidal Portman made contact in the 1880s, an encounter that reportedly ended badly for the islanders due to disease and violence. Indian anthropologists made a handful of friendly gift-giving expeditions in the 1970s through 1990s, but these were largely discontinued after the tribe consistently signaled they wanted no further contact, sometimes firing arrows at approaching boats and helicopters.
The 2018 incident
In November 2018, American missionary John Allen Chau paid local fishermen to illegally ferry him near the island, hoping to convert the Sentinelese to Christianity. He was killed by tribespeople shortly after reaching the shore. Indian authorities did not attempt to recover his body, citing the danger and the legal protections surrounding the island, and the case drew global attention to the ethics and legality of contacting isolated peoples.
Legal protection today
India enforces a strict exclusion zone of several nautical miles around North Sentinel Island under the Andaman and Nicobar Islands Protection of Aboriginal Tribes Regulation, making it a criminal offense to travel there or photograph the tribe from close range. The policy reflects both concern for the Sentinelese's total lack of immunity to outside diseases, which could wipe out the small population, and respect for their repeatedly expressed wish to be left alone.
