9. The Invasion of North Sentinel Island (Various)
Over the centuries, numerous outsiders have attempted to land on North Sentinel Island, aiming to establish contact or exploit its resources. The island is home to the Sentinelese, an indigenous tribe that has remained in voluntary isolation for thousands of years. These incursions have consistently been met with fierce resistance, resulting in the repulsion or death of the intruders. For instance, in 2006, two Indian fishermen were killed after their boat drifted too close to the island. In 2018, American missionary John Allen Chau was killed by the Sentinelese after attempting to evangelize them. More recently, in March 2025, a U.S. tourist illegally landed on the island, leaving behind offerings and recording a video before being arrested upon his return. These repeated failures underscore the tribe’s steadfast commitment to maintaining their isolation and the futility of external attempts to breach it (en.wikipedia.org).
