There are no official candidates for the papacy, but some cardinals are considered “papabile,” or possessing the characteristics necessary to become pope. After St. John Paul II broke the centurieslong Italian hold on the papacy in 1978, the field of contenders has broadened considerably.

The decision was made during a closed-door meeting of the College of Cardinals and announced at a media briefing at the Vatican.

Catholic cardinals on Monday set May 7 as the start date for the conclave to elect Pope Francis’ successor, delaying the secret voting for two days so they can get to know one another better and find consensus on a candidate before they are sequestered in the Sistine Chapel.
