History is full of supposed Messiahs and Saviors who founded religious movements and/or identified themselves as saviors (e.g. Joseph Smith and Raël). (By contrast, some messiahs were only venerated posthumously, possibly obscuring their actual wishes and intentions.)
Haile Selassie is a possibly unique example of an involuntary living messiah. Rastafarians considered his ascension to the Ethiopian throne to fulfill predictions of Marcus Garvey and the Book of Daniel. Selassie treated his unorthodox adherents respectfully, meeting them when he visited Jamaica in 1966 and allowing some to move to Ethiopia. He arranged to send an Ethiopian Orthodox mission to Jamaica and had no direct involvement in the Rastafarian movement.
Did anyone else happen to find themselves identified as a messiah for thousands of believers during their lifetime? Of course, a similar story was the premise of the comedy film "Life of Brian". Let's exclude quasi-religious subjection in the form of the divine right of kings or celebrity worship syndrome.
Or was Haile Selassie the world's only involuntary messiah?
