Francis’ successor will be selected by cardinals at the conclave that began on May 7. Cardinals, known as the “princes of the church,” rank just below the pope in the Roman Catholic Church; together, they are known as the College of Cardinals. When a pope dies, the college chooses a successor.

In this case, it took only two days for Catholic cardinals to elect a successor to Pope Francis. That’s among the shortest conclaves in recent decades, but not the shortest ever.

This selection comes after two days of conclave in the Sistine Chapel, tying the modern record for the fastest selection of a pope.
