North Sentinel Island is one of the Andaman Islands, and home to the Sentinelese, an indigenous people in voluntary isolation who have defended, often by force, their protected isolation from the outside world.

In 1956, the Government of India declared North Sentinel Island a tribal reserve and prohibited travel within 3 nautical miles (5.6 kilometers) of it.

That means people from outside world are strictly prohibited to enter this island

But why?

Well, If reports are to be believed, the Sentinelese tribe has been living on the island for more than 50000 years under the protection of the Indian Government, and They usually get violent and start attacking those who try to visit the island. That’s why entry is strictly prohibited for visitors.

In fact in 2018 an American tourist who tried to enter the island illegally was killed by the Sentinelese people.

Fishermen who took the man to North Sentinel Island say tribes people shot him with arrows and left his body on the beach.

He has been identified as John Allen Chau, a 27 year old from Alabama.

How many people live in North Sentinel Island?

Their population was estimated to be between 50 and 400 people in a 2012 report. But this date is not completely reliable as actual population is highly uncertain.

So hence this was some information about the tribe which is stilled untouched by the advanced human society.
