The death of a pope triggers a centuries-old ritual to elect a new one, involving sacred oaths, the piercing of ballots with a needle and the white or black smoke to signal whether cardinals have chosen a new leader for the world’s 1.3 billion Catholics.
Pope Francis' death at 88 early Monday set off the process. His body has been moved to St. Peter's Basilica for public viewing ahead of his funeral on Saturday with world leaders in attendance. Francis will be buried, according to his wishes, in a simple underground tomb at St. Mary Major Basilica in Rome.
