sentineles people

In the azure waters of the Bay of Bengal, lies a small, isolated island shrouded in mystery. North Sentinel Island, part of the Andaman archipelago, is home to the Sentinelese people, one of the last uncontacted tribes on the planet. Their fiercely guarded isolation and enigmatic way of life have fascinated the world for centuries. In this article, we will delve into the secrets of North Sentinel Island and the Sentinelese people while also uncovering some of the bizarre incidents that have occurred on this remote piece of land.

Geography and Location

Sentinelese island
  • North Sentinel Island is part of the Andaman and Nicobar Islands, which belong to India.
  • It covers an area of approximately 72 square kilometers (28 square miles).
  • The island is surrounded by coral reefs, which make it challenging to approach by sea.

A World Apart

Sentinelese people

The Sentinelese people are believed to have inhabited the island for thousands of years, living a hunter-gatherer lifestyle. Their isolation from the modern world has allowed them to maintain their unique cultural traditions and language. Their hostility toward outsiders and limited contact with the rest of humanity have contributed to their reputation as one of the last truly uncontacted tribes.

Mysterious Language and Culture

The Sentinelese language remains untranslatable, and their culture remains largely undocumented. Their small population, estimated to be between 50 and 200 individuals, is organized into family groups. Their survival on the island depends on their resourcefulness in hunting, fishing, and gathering.

Bizarre Incidents

The Sentinelese people have gained notoriety for their hostile reactions to outsiders. Several bizarre incidents have occurred when attempts were made to contact or study them:

  • 1970s Helicopter Incident: In 1974, a National Geographic film team attempted to make contact with the Sentinelese using a helicopter. The response was swift and violent, with the tribespeople showering the helicopter with arrows. Fortunately, the team managed to escape unharmed.
  • Lethal Incident with Poachers: In 2006, two fishermen who strayed too close to the island were killed by the Sentinelese. Their bodies were later buried on the beach.
  • Rescue of an Abandoned Sailor: In 1981, a cargo ship named “MV Primrose” ran aground near North Sentinel Island. The crew abandoned the ship, and a few days later, the Sentinelese were seen on the beach, brandishing spears and bows. They made it clear that they wanted the intruders to leave.
  • 2018 Death of American Missionary: In a tragic incident, an American Christian missionary, John Allen Chau, was killed by the Sentinelese in 2018 when he illegally attempted to make contact with them.
  • 1991 Anthropological Expedition: In 1991, the Indian government authorized an anthropological expedition to approach North Sentinel Island. The team, including Madhumala Chattopadhyay, a senior research officer with the Ministry of Social Justice and Empowerment, embarked on this historic journey. They left gifts for the Sentinelese on the beach and observed the tribe from a distance. While the Sentinelese did not engage in violent behavior during this particular visit, they made it clear they did not want contact and used gestures to communicate their wish for the outsiders to leave. It was during this expedition that Madhumala Chattopadhyay made history by establishing the first friendly contact with the Sentinelese, offering coconuts as a gesture of goodwill. Her presence as a woman played a pivotal role in signaling the non-threatening nature of the visiting party. Subsequent visits in February 1991 were received with welcoming arms, marking a unique and less hostile aspect of the Sentinelese culture.

Protecting Their Isolation


The Indian government, recognizing the need to preserve the Sentinelese culture and protect both the tribe and outsiders from potential diseases, has declared a 3-mile exclusion zone around the island. It is illegal to approach North Sentinel Island, and any attempt to make contact is met with strict legal consequences.

Conservation Efforts

Efforts to monitor the Sentinelese from a distance aim to ensure their well-being without direct contact. Conservationists and anthropologists are dedicated to respecting their isolation and preserving their unique culture, all while keeping a watchful eye on this remarkable society.



North Sentinel Island and its Sentinelese inhabitants continue to be a subject of intrigue and mystery. While their way of life remains largely enigmatic, their fierce determination to protect their isolation and unique culture has earned them respect from the international community. As the world changes rapidly, the Sentinelese stand as a testament to the endurance of cultures untouched by time.
The Sentinelese people’s ability to survive for thousands of years in isolation, without the benefits of modern technology and knowledge, is a testament to the resilience of human communities in challenging conditions. Their adaptation to the natural resources available on their island and their determination to protect their way of life in the face of encroachment is a compelling story of survival.
