The Sentinelese are indeed one of the world's last uncontacted tribes, residing on North Sentinel Island in India's Andaman and Nicobar Islands.

Location and Habitat

North Sentinel Island lies off India's southeastern coast in the Bay of Bengal, spanning about 23 square miles with dense forests and fringing reefs that enhance its isolation.

Historical Timeline

They are thought to have inhabited the region for up to 60,000 years, descending from early African human migrations and sharing traits with other Negrito groups like the Onge. First recorded outsider sightings date to the 1700s–1800s, with limited contacts in 1867 and the 1990s led by Indian anthropologists, but these turned hostile.

Isolation Policy

India enforces a strict no-contact zone with a 3-mile (5 km) exclusion radius under the 1956 Aboriginal Tribes Regulation to shield them from diseases—they lack immunity—and exploitation. Population estimates range from 50–200 based on aerial surveys.
