Fun Fact: 99 year old Prince Philip is believed, by the Kastom people of the island of Tanna in Vanuatu (a south Pacific archipelago) to be a god.
(a condensed version of the wikipedia article)
According to ancient Yaohnanen tales, the son of a mountain spirit travelled over the seas to a distant land. There, he married a powerful woman and in time would return to them.
The people of the Yaohnanen area believe that Prince Philip, Duke of Edinburgh, must be this mythical figure. They had seen the respect accorded to Queen Elizabeth II by the colonial officials and concluded that her husband, Prince Philip, must be the son referred to in their legends.
It is unclear just when this belief came about, but it was probably some time in the 1950s or 1960s. It was strengthened by the royal couple's official visit to Vanuatu in 1974, when a few villagers had the opportunity to actually see Prince Philip from a distance. The Prince was not then aware of the sect, but it was brought to his attention several years later by John Champion, the British Resident Commissioner in the New Hebrides.
Champion suggested that Prince Philip send them a portrait of himself. He agreed and sent a signed official photograph. The villagers responded by sending him a traditional pig-killing club called a nal-nal. In compliance with their request, the Prince sent a photograph of himself posing with the club. Another photograph was sent in 2000.
Princess Anne (Prince Philip's daughter) visited Tanna in October 2014. She had visited Vanuatu in 1974, but had not previously travelled to the island.
In 2007, five Tanna men from the Prince Philip Movement visited Britain. Their trip culminated in an audience with Philip, where gifts were exchanged, including a new photograph of the Prince.
