In November 2018, 26-year-old American missionary John Allen Chau was killed by the Sentinelese people on North Sentinel Island in the Indian Ocean.
The young adventure blogger and evangelical Christian had spent years getting ready for this trip. He believed it was his life’s purpose to bring Christianity to one of the world’s last uncontacted tribes. His death started a big debate around the world about missionary work, the rights of native people, and the dangers of trying to contact isolated communities.
