🔑 What Is a Conclave?
A conclave is the formal gathering of the College of Cardinals to elect a new pope when the papacy is vacant—either after a pope dies or resigns (as Benedict XVI did in 2013).
The name “conclave” comes from the Latin cum clave, meaning “with a key.” This refers to the strict isolation under which the cardinals gather—traditionally, they are “locked in” to prevent outside influence.

🔍 When Does a Conclave Happen?
- Upon the death of a pope (most common scenario)
- After a papal resignation (e.g., Pope Benedict XVI in 2013)
The period of vacancy is called “sede vacante”—meaning “the seat is vacant.” To fully understand how is a Pope chosen, we need to explore both the spiritual and procedural aspects of the conclave.
🏛️ A Brief History of the Papal Conclave
While popes have been elected since the early Church, the conclave process as we know it was formalized in 1274 at the Second Council of Lyon. Before that, elections were often disorganized and influenced by politics, monarchs, or even mobs.

⏳ Key Developments:
| Year | Milestone |
|---|---|
| 1059 | Pope Nicholas II limited voting rights to cardinals |
| 1274 | Conclave procedures defined by Pope Gregory X |
| 1621 | Paper ballots introduced |
| 1903 | Political vetoes banned (Papal Veto) |
| 1970 | Voting age limited to cardinals under 80 |
| 1996 | Pope John Paul II updated rules (Constitution Universi Dominici Gregis) |
🧑🦳 Who Votes in a Conclave?
The College of Cardinals is responsible for electing the new pope. Not all cardinals can vote—only those under the age of 80 on the day the papacy becomes vacant.
🗳️ Voter Profile:
- All cardinals under 80 years old
- Maximum number of electors: 120
- Most are bishops or archbishops appointed by previous popes
These cardinals are called cardinal electors. They come from all over the world, reflecting the global nature of the Church.
🧾 How Does the Voting Process Work?
The voting takes place in the Sistine Chapel at the Vatican. The process is highly ritualized, secret, and solemn.
🕊️ Step-by-Step Voting Procedure:
- Mass & Oath: Before the conclave begins, cardinals attend the “Pro Eligendo Papa” Mass. They swear oaths of secrecy and commit to electing the new pope faithfully.
- Sealing Off: The doors of the Sistine Chapel are closed (extra omnes), and only cardinals remain.
- Balloting:
- Each cardinal writes a name on a ballot.
- They approach the altar and place it in a chalice.
- Three cardinals count the votes.
- A two-thirds majority is required to elect.
- Burning the Ballots:
- Ballots are burned after each round.
- Black smoke (fumata nera) = No pope elected.
- White smoke (fumata bianca) = Pope elected.

Usually, up to four votes occur each day—two in the morning, two in the afternoon.

🎉 What Happens When a Pope Is Elected?
When someone receives a two-thirds majority and accepts the position, the process immediately moves into the public announcement phase.
📣 Key Rituals:
- The dean of the cardinals asks: “Do you accept your canonical election as Supreme Pontiff?”
- Upon acceptance, the new pope chooses a papal name.
- He is dressed in white papal garments (prepared in various sizes).
- Cardinal Protodeacon announces:
“Habemus Papam” – “We have a Pope!” - The new pope appears on the balcony of St. Peter’s Basilica and gives his first blessing to the people.
