Joseph Di Mambro and Luc Jouret founded The Order of the Solar Temple. They told their followers that the world would end in 1995, but if they killed themselves, they would be reborn on the star Sirius.

How were Di Mambro and Jouret able to convince so many followers to die for something they likely knew not to be true?
