The longest conclave in history lasted nearly three years, spanning 1,006 agonizing days between November 1268 and September 1271. Triggered by the death of Pope Clement IV, this political stalemate in Viterbo, Italy, redefined how the Catholic Church chooses its leaders and gave birth to the modern concept of the conclave.
Long before white smoke drifted over the Sistine Chapel, papal elections were messy affairs marred by intense geopolitical meddling, bitter factionalism, and extreme coercion. Understanding this historic marathon reveals the roots of modern Vatican governance and the strict rules designed to prevent another multi-year vacancy.
The Roots of the 1268 Deadlock
When Pope Clement IV died in Viterbo on November 29, 1268, the College of Cardinals gathered to find a successor. They faced a deeply divided house. Twenty cardinals split into rigid factions, primarily driven by Mediterranean royal politics:
- The French faction: Supported by Charles of Anjou, King of Sicily, who wielded heavy influence over Italian peninsula politics.
- The anti-French faction: Composed of cardinals resisting Angevin expansion and seeking to protect traditional papal autonomy.
Neither side could secure the required two-thirds majority. Weeks turned into months, and months into years. As the cardinals argued, several elderly prelates died from natural causes and illness brought on by prolonged confinement, further shrinking the voting pool and deepening the gridlock.

Clamped Down: The Birth of Clavis
The word conclave stems from the Latin phrase cum clave, meaning "with a key". This term originated directly from the extreme measures taken by the citizens of Viterbo to force a decision out of the stubborn clerics.
Frustrated by nearly three years of inaction, the local magistrates and townspeople took matters into their own hands. They locked the cardinals inside the papal palace to cut off outside interference and communication. When that failed to break the deadlock, the authorities took even more drastic steps:
- They reduced the cardinals' daily rations to a bare minimum of bread and water.
- As winter elements beat down, the exasperated townspeople reportedly ripped the roof off the building entirely, exposing the electors to the open sky.
This brutal coercion finally worked. Forced to compromise, the remaining cardinals delegated their voting power to a committee of six members. This committee elected Tedaldo Visconti, an archdeacon who wasn't even present in Italy at the time—he was away participating in the Ninth Crusade. Taking the name Pope Gregory X, he did not arrive in Viterbo to assume office until early 1272, more than three years after Clement IV's death.
Institutional Reforms: Ubi Periculum
Determined to ensure a crisis like the Viterbo stalemate never happened again, Pope Gregory X issued the papal bull Ubi Periculum at the Second Council of Lyon in 1274. This document established the formal framework for papal elections that, with minor modifications, still influences modern Vatican procedures.
Key rules introduced by Gregory X included:
- Strict Isolation: Cardinals had to live in a secure, enclosed space without private quarters or external communication.
- Ration Penalties: If an election dragged past three days, cardinals were restricted to a single meal a day. If it stretched past eight days, their diet was reduced strictly to bread, water, and a small allowance of wine.
- Financial Cutoffs: While sequestered, cardinals lost all rights to collect revenues from their individual church offices, cutting off financial incentives to drag out negotiations.
Though some of the harsher dietary penalties were relaxed or altered by later pontiffs, the core principle of total isolation remained untouched.
Modern Contrast: How Conclaves Work Today
Today's papal elections bear little resemblance to the grueling ordeal of the thirteenth century. Modern popes, governed by Universi Dominici Gregis, reside in the comfortable Domus Sanctae Marthae guest house within Vatican City during the voting process.
While secrecy remains absolute—and electronic jamming devices are deployed to block any outside signals—the sheer speed of modern elections makes multi-year vacancies a relic of the past. Recent elections, such as the ones that chose Pope Benedict XVI and Pope Francis, concluded within just a few days.
Frequently Asked Questions
Why did the 1268-1271 election take so long?
The delay stemmed from an intense political split between French royal interests and anti-French factions within the College of Cardinals. Neither side could reach the necessary two-thirds majority, and political interference prevented compromise until the citizens of Viterbo intervened.
Who won the longest conclave in history?
Tedaldo Visconti was chosen as the compromise candidate and took the name Pope Gregory X. Because he was traveling abroad on a crusade, his coronation took place months after his selection.
Are modern cardinals still locked in with a stripped roof?
No. While modern cardinals are still isolated from the outside world during the voting process, they stay in comfortable Vatican housing and enjoy standard meals, thanks to reforms implemented over the centuries following Gregory X's strict medieval mandates.
What is the shortest conclave on record?
While pre-1274 elections occasionally saw same-day choices, the fastest modern elections typically wrap up within 24 to 48 hours over just a few ballots. Pope Julius II in 1503 was famously elected in just a few hours.
