The Last Sentinels: Ancient Tribes of the Andaman and Nicobar Islands

The Andaman and Nicobar Islands, an emerald archipelago in the Bay of Bengal, are home to some of the most ancient and isolated human populations on Earth. These tribes are broadly classified into two groups based on their origin: the Negrito tribes of the Andaman Islands and the Mongoloid tribes of the Nicobar Islands.

Their stories are a profound testament to human resilience, but they also serve as a cautionary tale about the fragile balance between traditional life and modern encroachment.


The Negrito Tribes of the Andamans

The tribes of the Andaman Islands—the Great Andamanese, Onge, Jarawa, and Sentinelese—are believed to have arrived from Africa roughly 60,000 years ago. They are hunter-gatherers who have maintained a Paleolithic lifestyle for millennia.

  • The Sentinelese: Perhaps the most famous, they reside on North Sentinel Island and are known for their fierce rejection of any contact with the outside world. They remain one of the last “uncontacted” tribes globally.+1
  • The Jarawa: For centuries, they lived in total isolation. However, the construction of the Andaman Trunk Road has brought them into forced proximity with modern civilization, leading to issues with disease and cultural dilution.+1
  • The Onge: Inhabiting Little Andaman, the Onge are skilled forest dwellers. Their population has dwindled significantly, and they now live in government-established settlements.
  • The Great Andamanese: Once the largest group, they were devastated by diseases introduced during the British colonial era. Today, only a small number remain, living on Strait Island.

The Mongoloid Tribes of the Nicobars

The Nicobar Islands house two primary groups: the Nicobarese and the Shompen. Unlike their Andamanese neighbors, these tribes show linguistic and genetic affinities with Southeast Asian populations.

  • The Nicobarese: They are the most populous and “modernized” of the groups. They are horticulturalists, famously skilled in coconut farming and pig rearing. Many have embraced Christianity and participated in the local economy.
  • The Shompen: Residing in the interior of Great Nicobar, the Shompen are semi-nomadic hunter-gatherers. They are shy and largely avoid the coastal Nicobarese, maintaining a lifestyle centered around the tropical rainforest.

The Struggle for Survival

The survival of these tribes is currently hanging in a delicate balance. They face three primary threats:

  1. Epidemics: Having lived in isolation, their immune systems are not equipped to handle common “mainland” illnesses like measles or the flu.
  2. Habitual Loss: Infrastructure projects and deforestation threaten the biodiversity of the forests they rely on for food and medicine.
  3. Cultural Erosion: The pressure to assimilate into “civilized” society often leads to the loss of unique languages, oral traditions, and survival skills that have been passed down for sixty thousand years.

A Note on Ethics: The Indian government follows a “Eyes on, Hands off” policy for the more isolated tribes, aiming to protect their territory while minimizing direct interference. Respecting their sovereignty is crucial for their continued existence.


The Andaman and Nicobar tribes are not “living fossils”; they are vibrant, contemporary societies that have mastered the art of living in harmony with nature. Protecting them isn’t just about preserving the past—it’s about respecting the diversity of the human experience.
