# When the Pope dies, the head of the Sacred College of Cardinals, or Camerlengo, verifies the death. Standing over the deceased, he calls the pontiff by his baptismal name three times. Upon receiving no response, he announces the death and arranges for the Fisherman's ring -- inscribed with the name of the reigning pope -- and papal seal to be broken. Later, another ring will be made for the newly elected pope. The Camerlengo then prepares for the Pope's burial and the traditional nine days of mourning. Assisted by three officials elected from the college, he directs the election of the pontiff's successor.
# Fifteen to 20 days after the death of the Pope, the Sacred College of Cardinals meets for the election. Hailing from every corner of the globe, the cardinals are handpicked by the pope to advise and help him. There are currently 123 voting cardinals.
# After a Mass of the Holy Spirit in St. Peter's Basilica, the cardinals enter a guarded annex of the Sistine Chapel for the election process, known as a conclave. Each cardinal swears an oath to protect the secrecy of the election. Breaking the oath carries a penalty of immediate excommunication. Literally locked within the walls of the annex, which is screened for bugging devices, the cardinals are sequestered from any contact with the outside world. Entrances are sealed and curtains closed.
# The next morning, the cardinals attend mass in the Sistine Chapel and the electoral session begins. According to the reforms of Pope Paul VI, only cardinals under the age of 80 may vote. While for centuries only cardinals have been elected pope, in theory, any adult male Roman Catholic is papabile, or a potential candidate for the papacy.
# The election is conducted in secret written ballots counted by the Camerlengo and his three assistants. In the past, a pope needed two thirds of the vote plus one to be elected. In 1996, however, Pope John Paul II changed this rule so that if the votes continue to be unsuccessful for 12 or 13 days, the cardinals may agree by absolute majority (half plus one) to elect.
# Two ballots are taken each morning and two each afternoon until a successful vote is completed. After each voting session, ballots are burned. If the vote is inconclusive, a chemical substance is added to the paper to produce black smoke. Billowing from the roof of the Vatican Palace, the smoke is a message to the crowds watching in St. Peter's Square that the church is still without a pope.
# When the college eventually reaches the final decision, each cardinal lowers a purple canopy over his chair, leaving the elected Pope's canopy folded. The final ballots are burned and their white smoke signals a successful election. The dean of the cardinals asks if the chosen member accepts the papacy. Upon accepting, the new pontiff is made bishop of Rome and is honored by each of the cardinals.
# The dean then steps out onto the balcony of the Vatican, shouting "Habemus papam!" ("We have a Pope!") The new pontiff then appears to greet and bless the waiting world.
