Catholic cardinals are gathering at the Vatican to elect the successor to Pope Francis, who died on April 21. Voting will take place in the Sistine Chapel, with ballots continuing in succession until any candidate secures two-thirds of the available votes.

As cardinals gather at the Sistine Chapel to begin voting for a successor to Pope Francis, there is no single frontrunner, and it remains unclear whether the new pope will align with Francis’s more inclusive ideology.

Mass was held in St. Peter’s Basilica hours before 133 cardinals began the conclave to select the man who will replace Pope Francis as the next pontiff.
