The election of a new pope is one of the most iconic events in the Catholic Church, marked by centuries of tradition and a meticulously regulated process. Held in the Sistine Chapel, the conclave brings together cardinals from around the world in an environment of absolute secrecy to decide who will be the next spiritual leader of over 1.3 billion Catholics. This ritual, blending spirituality, complex logistics, and symbolism, sparks global curiosity, especially after the death or resignation of a pontiff. With recent discussions about papal succession, understanding how the conclave works and its duration is essential to follow this historic moment.
The term “conclave” comes from the Latin cum clave, meaning “with key,” referring to the medieval practice of locking cardinals in an isolated location until they chose a new pope. This tradition began to take shape in the 13th century, following prolonged disputes that left the Church without leadership for months or even years. Today, the process is governed by the Apostolic Constitution Universi Dominici Gregis, issued by John Paul II in 1996 and amended by Benedict XVI in 2007 and 2013, ensuring greater efficiency and protection against external interference.
The conclave is not just a vote but a deeply spiritual event. The cardinals, considered the pope’s primary advisors, gather in a sacred space under Michelangelo’s Last Judgment fresco to invoke the guidance of the Holy Spirit. The election requires significant consensus, with the candidate needing two-thirds of the votes, which often extends deliberations.
Historical origins of the conclave
The conclave as we know it today was formalized in 1274 during the Second Council of Lyon by Pope Gregory X. The decision came after the longest election in history, from 1268 to 1271 in Viterbo, which lasted 1,006 days due to political disputes and lack of consensus among the 15 voting cardinals. Frustrated, the city’s residents locked the cardinals in a palace, reduced their food to bread and water, and even removed the building’s roof, forcing a decision. The result was the election of Gregory X, who, to prevent future delays, issued the document Ubi Periculum, establishing strict rules for papal elections.
Before the 13th century, the selection of popes was less structured. In the early centuries of Christianity, the bishops of Rome, like other bishops, were chosen by consensus among clergy and laity of the diocese. The creation of the College of Cardinals in 1059 defined an exclusive group of electors, but elections were still vulnerable to pressures from kings, nobles, and internal Church factions. The Ubi Periculum introduced the isolation of electors, limited the number of assistants, and set a standard that, with adjustments over the centuries, remains in place today.
How the conclave is organized
Preparations for the conclave begin immediately after the death or resignation of the pope, a period known as Sede Vacante. The camerlengo, a cardinal responsible for administering the Church during this interval, takes on critical tasks, such as officially verifying the pontiff’s death, sealing his apartments, and summoning the College of Cardinals. The conclave must start between 15 and 20 days after the vacancy, allowing cardinals from around the world to arrive at the Vatican.
The voting cardinals, all under 80 years old at the time of the vacancy, stay at the Domus Sanctae Marthae, a residence within the Vatican. During the conclave, they are completely isolated from the outside world, with no access to phones, the internet, or any means of communication. This seclusion ensures confidentiality and protects the process from external influences.
- Oath of secrecy: Before voting, cardinals take a solemn oath, pledging to keep the deliberations secret under penalty of excommunication.
- Sistine Chapel: Voting takes place in the Sistine Chapel, a sacred space that underscores the gravity of the moment.
- Symbolic smoke: After each voting round, ballots are burned. Black smoke indicates no candidate reached the required two-thirds, while white smoke signals the election of the new pope.
- Extra omnes: After the oath, the master of liturgical ceremonies issues the order “extra omnes” (everyone out), and all non-participants leave the chapel.
The voting process
The papal election is a meticulous process designed to ensure consensus and legitimacy. On the first day of the conclave, only one vote is held. From the second day onward, up to four votes occur daily, two in the morning and two in the afternoon. Each cardinal writes their chosen candidate’s name on a rectangular ballot inscribed with Eligo in Summum Pontificem (I elect as Supreme Pontiff). The vote is secret, and cardinals cannot vote for themselves.
Three cardinals, chosen by lot as scrutineers, count the votes. Another three, the revisers, verify the count, and three infirmarii collect votes from cardinals who are ill. After the count, the ballots are burned in a special stove in the Sistine Chapel. A chemical is added to ensure the smoke is clearly black or white, avoiding confusion, as happened in past conclaves, such as in 1958.
If no candidate achieves two-thirds after three days, the conclave pauses for a day of prayer and reflection. This cycle can repeat up to seven times. If consensus is still not reached, the two cardinals with the most votes enter a final runoff, where a simple majority decides the winner. The elected is then asked by the cardinal dean: “Do you accept your canonical election as Supreme Pontiff?” and, if affirmative, “By what name do you wish to be called?” The new pope chooses his name and is presented to the world with the announcement Habemus Papam.
How long the conclave lasts
The duration of the conclave varies depending on the consensus among cardinals. In modern history, conclaves have been relatively short, rarely exceeding five days. The 1939 conclave, which elected Pius XII, lasted two days and three votes, while the 1922 conclave, which chose Pius XI, took five days and 14 votes. In contrast, medieval conclaves could last months or years, such as the 1292-1294 conclave, which took 27 months to elect Celestine V.
In the contemporary era, the average is two to four days. The 2005 conclave, which elected Benedict XVI, and the 2013 conclave, which chose Francis, both lasted two days. Modern efficiency is due to rules limiting the number of electors to 120 and imposing a strict voting schedule.
- 1268-1271 conclave: 1,006 days, the longest in history, in Viterbo.
- 1503 conclave: One day, the shortest, electing Julius II.
- 2013 conclave: Two days, resulting in the election of Francis.
- 1939 conclave: Three votes in two days, electing Pius XII.
Symbolism and traditions
The conclave is rich in symbolism that reflects its spiritual and historical significance. The smoke, black or white, is one of the most recognizable elements, capturing global attention as the faithful wait in St. Peter’s Square. The practice dates to the 20th century, when chemicals made the smoke’s color more distinct. Before that, burning ballots with wax or wet straw often produced unclear results, causing confusion.
The Sistine Chapel, built between 1473 and 1481 under Pope Sixtus IV, has been the heart of the conclave since the 15th century. Its isolation and architectural beauty create an environment conducive to spiritual reflection. Michelangelo’s Last Judgment fresco serves as a constant reminder of the cardinals’ responsibility to choose a leader who will guide the Church wisely.
Another striking symbol is the Habemus Papam, announced by the cardinal protodeacon from the balcony of St. Peter’s Basilica. The phrase, followed by the new pope’s name and chosen name, marks the end of the conclave and the start of a new pontificate. The new pope then delivers his first apostolic blessing, Urbi et Orbi, to the city and the world.
Rules and restrictions
The conclave’s rules are designed to protect the process’s integrity. The Apostolic Constitution Universi Dominici Gregis prohibits any form of campaigning or agreements among cardinals to influence votes, under penalty of excommunication. Until the early 20th century, Catholic monarchs had veto power, a practice abolished by Pius X in 1914. Today, any attempt at external interference is severely punished.
Cardinals are also forbidden from revealing voting details, even after the conclave. This confidentiality ensures deliberations remain free from pressure and speculation. Conclave staff, such as secretaries and doctors, also take oaths of secrecy, reinforcing the process’s security.
- Communication ban: Phones, internet, and any external contact are prohibited.
- Excommunication penalty: Applied to those who break secrecy or attempt to manipulate the election.
- Elector limit: Maximum of 120 cardinals under 80 years old.
- Secret vote: Ensures freedom of choice without internal pressures.
The camerlengo’s role
During the Sede Vacante, the camerlengo plays a central role. He is responsible for managing the Church’s assets, organizing the deceased pope’s funeral, and preparing the conclave. After the pontiff’s death, the camerlengo officially verifies the passing in the presence of other Vatican officials and issues the death certificate. He also destroys the Ring of the Fisherman, a symbol of the papacy, and seals the papal apartments to preserve their privacy.
The camerlengo presides over the preparatory meetings of the College of Cardinals, known as General Congregations, where cardinals discuss the desired profile for the new pope. These meetings, held before the conclave, help align expectations and clarify the Church’s needs at a given historical moment.
The choice of papal name
After the election, the new pope chooses a name that reflects his mission or honors predecessors. The tradition of changing names began in the 6th century when Mercury, elected pope, chose John II, rejecting his pagan name. Since then, most popes adopt a new name, often inspired by apostles, saints, or previous pontiffs.
For example, John Paul I, elected in 1978, combined the names of his predecessors, John XXIII and Paul VI, as a tribute. Jorge Mario Bergoglio chose Francis in 2013, inspired by St. Francis of Assisi, signaling a pontificate focused on simplicity and the poor. The choice of name is one of the new pope’s first acts and carries significant symbolic weight.
Global impact of the conclave
The election of a new pope transcends the Catholic Church’s boundaries, influencing social, political, and cultural debates worldwide. The 2013 conclave, which elected Francis, marked a historic moment by choosing the first Latin American pope, reflecting the growing influence of peripheral regions in the Church. The diversification of the College of Cardinals, promoted by Francis, with greater representation from Asia, Africa, and Latin America, suggests future conclaves may bring leaders from even more diverse backgrounds.
The conclave also attracts global media attention. Thousands of journalists and faithful gather in St. Peter’s Square, tracking each smoke signal and speculating about potential candidates. The papal election is a rare moment when the Catholic Church takes center stage globally, highlighting its spiritual and cultural relevance.
Conclave curiosities
The conclave is full of details that capture the public’s imagination. Beyond the smoke and isolation, there are lesser-known aspects that enrich its history.
- Special urns: Since 2005, ballots are placed in gold, silver, and bronze urns designed by Italian sculptor Cecco Bonanotte.
- Infirmarii cardinals: Ill cardinals can vote from their quarters, with votes collected by designated colleagues.
- Perforated ballots: After counting, ballots are pierced at the word Eligo and tied together before burning.
- Historical confusion: In 1958, ambiguous smoke caused uncertainty about John XXIII’s election, leading to process adjustments.
Typical conclave timeline
The conclave follows a strict timeline designed to balance deliberation and efficiency. While duration varies, the process is structured to avoid excessive delays.
- Day 1: Mass Pro Eligendo Pontifice in St. Peter’s Basilica, followed by one vote in the Sistine Chapel.
- Day 2 onward: Up to four votes daily (two in the morning, two in the afternoon) until the election.
- Pause after three days: If no consensus is reached, cardinals take a 24-hour break for prayer.
- Final runoff: After seven cycles without a winner, the two top candidates compete for a simple majority.
Modern challenges of the conclave
Although the conclave is a well-established ritual, it faces contemporary challenges. The globalization of the Church, with cardinals from over 50 countries, requires greater logistical coordination. Cultural diversity can complicate consensus, especially on issues like inclusion, morality, and the Church’s role in the modern world. Additionally, media pressure and speculation about candidates make secrecy an ongoing challenge.
Cybersecurity is also a concern. While cardinals are isolated, the Vatican takes measures to prevent leaks, such as electronic sweeps in the Sistine Chapel to detect recording devices. These precautions reflect the need to adapt a medieval ritual to 21st-century realities.
The future of conclaves
With the appointment of cardinals from previously underrepresented regions like Asia and Africa, the profile of future conclaves is changing. This diversity could lead to popes with innovative perspectives, capable of addressing global issues like climate change, inequality, and interfaith dialogue. The conclave, though rooted in tradition, evolves to reflect the Church’s universality.
The next conclave, expected in the coming years, will test this transformation. The choice of Francis’s successor will depend on how cardinals interpret his legacy of openness and reform. Regardless of the outcome, the conclave will remain a symbol of continuity and renewal, bridging past and future in one of history’s most fascinating rituals.
