When the cardinals meet for the conclave, they gather in the Sistine Chapel. All cardinal electors must swear an oath of secrecy and vote by secret ballot. A two-thirds majority is needed to elect a new pope, and campaigning is part of the process, though it should not appear so.

World leaders, cardinals and at least 250,000 of the faithful gathered in the Vatican on Saturday morning to bid farewell to Pope Francis.

Crowds of mourners waited in line on Sunday for a chance to visit Pope Francis’ final resting place in the Santa Maria Maggiore church in Rome, a day after his funeral service that was attended by world leaders and royalty.
