How a Pope Is Elected
For 900 years, electing a pope has been the prerogative of the College of Cardinals meeting in conclave. The cardinals meet in Rome 15 to 20 days after the death of a pope and pick a successor from among themselves in secret balloting. Pope John Paul II wrote the rules for electing his successor.
