You’ve probably seen the white smoke. It’s that iconic, cinematic moment when the world stops to look at a chimney in Rome. But if you think the history of the papacy is just a long, dusty line of saintly men in robes praying in quiet rooms, you're missing the best parts. It is actually a story of survival. It’s a story about how a small group of underground believers in a Roman suburb turned into the world’s oldest functioning institution.
Honestly, it’s a miracle the office even exists today.
Between the assassinations, the literal wars, and the moments where there were three different guys all claiming to be the "real" Pope at the same time, the timeline is a mess. It’s a fascinating, human mess. We’re talking about an office that has outlasted the Roman Empire, the Vikings, the Black Death, and the rise and fall of the Soviet Union. To understand how it stuck around, you have to look past the stained glass.
The Rough Start in a Roman Basement
It started with a fisherman. Tradition says Peter was the first, but he wasn't exactly living in a palace. He was a fugitive. In those early years, being the Bishop of Rome was basically a death sentence. Most of the early leaders ended up executed by the state. There was no "Vatican City" back then; it was just a network of house churches and catacombs.
Then came Constantine.
Everything changed in 313 AD with the Edict of Milan. Suddenly, Christianity wasn't illegal. The Emperor started throwing money and land at the church. This is where the history of the papacy takes a sharp turn from spiritual leadership into political powerhouse. By the time the Western Roman Empire collapsed in 476, the Pope was often the only person in Italy with a functioning administration. When the Goths and Vandals showed up to burn things down, they didn't talk to a General; they talked to Pope Leo I.
He literally stepped out to meet Attila the Hun to talk him out of sacking Rome. That’s not just theology. That’s high-stakes crisis management.
When Things Got Truly Wild: The Cadaver Synod
If you want to know why people get obsessed with the darker side of this history, look up the year 897. This period is often called the Saeculum Obscurum. It was chaotic.

Pope Stephen VI was so angry at his predecessor, Formosus, that he had the man's rotting corpse dug up. He dressed the body in papal robes, sat it on a throne, and put it on trial. They called it the Cadaver Synod. A deacon had to stand behind the corpse and speak for it. Unsurprisingly, the corpse lost the trial. They chopped off the body's "blessing fingers" and tossed it in the Tiber River.
It sounds like a horror movie. It was actually just 9th-century Italian politics.
The papacy had become a trophy for powerful Roman families. The Theophylacti family, and specifically a woman named Marozia, basically controlled who sat on the throne for decades. This wasn't about the Bible; it was about who owned the most land and had the most soldiers. If you ever feel like modern politics is a circus, remember that we haven't reached the "put a corpse on trial" phase yet.
Power, Politics, and the Great Schism
By the middle ages, the Pope was a king. Period. He had his own armies. He had his own taxes. The "Papal States" were a real country in the middle of Italy. This caused a massive rift with the East.
In 1054, the Church split in two—the Great Schism. The Pope in Rome and the Patriarch in Constantinople essentially broke up via a very formal, very angry series of excommunications. This created the Catholic and Orthodox divide we still see today.
The Avignon "Vacation" and the Triple Pope Problem
For a while in the 1300s, the Popes didn't even live in Rome. They moved to Avignon, France. It was basically a golden cage under the thumb of the French King. When they finally tried to move back to Rome, things broke.
- Rome elected a Pope.
- The French cardinals got mad and elected a different Pope.
- For years, they both claimed to be the boss.
- A council tried to fix it by electing a third guy, but the first two refused to quit.
For a hot minute, you had three Popes all excommunicating each other. It was a PR nightmare that took years to resolve at the Council of Constance. This mess is why the history of the papacy is so central to Western history; you can't understand the Protestant Reformation without understanding how much the prestige of the office had slipped during these power struggles.

The Renaissance Popes: Art and Scandal
We have to talk about the Borgias. Alexander VI is the name most people know, mostly because of the rumors of poisonings and wild parties. While some of the stories are likely exaggerations by his enemies, he was definitely more of a prince than a priest.
But this era also gave us the Sistine Chapel.
Julius II, the "Warrior Pope," was more comfortable in armor than in a miter. He’s the one who bullied Michelangelo into painting that ceiling. Without the ego and the massive wealth of these Renaissance Popes, we wouldn't have half the masterpieces in the Vatican Museums. They were patrons of the arts on a scale the world had never seen, even if their personal lives were... complicated.
Losing the Land but Gaining the World
The biggest shift in the modern history of the papacy happened in 1870. Italy was unifying into one country. They marched into Rome and took the Papal States away. Pope Pius IX called himself a "prisoner in the Vatican" and refused to leave.
It felt like the end. It was actually a rebranding.
Without a country to run or armies to lead, the Pope became a purely moral and spiritual figurehead. The Lateran Treaty of 1929 finally settled the beef, creating the tiny, 100-acre Vatican City State we know today. It’s the smallest country in the world.
In the 20th century, the role changed again with the advent of mass media.

- Pius XII had to navigate the horrors of World War II and the Holocaust, a topic that historians like Mark Riebling (Church of Spies) still debate fiercely today regarding how much he did behind the scenes.
- John XXIII called Vatican II in the 60s, basically trying to drag a medieval institution into the modern world. They stopped saying the Mass in Latin and started looking at other religions with more respect.
- John Paul II became a global celebrity. He traveled more than every previous Pope combined. He used the "Bully Pulpit" to help take down Communism in his native Poland.
What Most People Get Wrong
People often think the Pope is "infallible" in everything he says. That’s a huge misconception. In the context of the history of the papacy, the doctrine of Papal Infallibility (defined in 1870) is actually very narrow. It only applies when he speaks "Ex Cathedra" on specific matters of faith or morals. It’s only been used officially a couple of times in over 150 years. He can be wrong about the weather, he can be wrong about politics, and he can definitely be wrong about who’s going to win the World Cup.
Another myth is that the archives are "secret" because they’re hiding aliens or Da Vinci Code secrets. The "Vatican Apostolic Archive" is actually open to qualified scholars. The "secret" part comes from a mistranslation of the Latin secretum, which just means "private." It's more like a private filing cabinet than a conspiracy lair.
Why It Still Matters Today
The papacy is the ultimate "soft power" play. Pope Francis, for example, doesn't have a single tank or fighter jet. Yet, when he writes an encyclical about climate change or economic inequality, world leaders have to react.
The history of the papacy teaches us about the endurance of institutions. It shows how an office can survive its own worst leaders and its most crushing defeats. It’s a mirror of Western civilization—sometimes inspiring, often corrupt, but always influential.
How to Explore This History Yourself
If you actually want to get a handle on this without reading a 900-page textbook, here is how you should start.
First, don't just look at the list of names. Look at the "pivotal" years: 313, 1054, 1517, and 1870. Those are the hinges the door swings on. If you're ever in Rome, skip the main line for a second and go to the Basilica of Saint Paul Outside the Walls. There’s a long row of mosaic portraits of every single Pope in history. There are a few empty spots left. Whether you're religious or not, standing under that timeline makes you realize how long this game has been going on.
Read Eamon Duffy’s Saints and Sinners. It’s widely considered the gold standard for a fair, academic, yet readable account of how the office evolved. He doesn't sugarcoat the bad parts, and he doesn't ignore the impact of the good ones.
Understand that the papacy isn't just a religious role; it’s a diplomatic one. It is the only entity that has a seat at the table in almost every major historical shift in the West for the last 2,000 years. To know the Pope is to know the history of Europe, for better or worse.
Start by looking at the lives of the "Greats"—Gregory the Great or Leo the Great. See how they handled the collapse of society. Then, compare them to the modern era. You'll see that while the tools change (from parchment to Twitter), the struggle to maintain authority in a changing world stays exactly the same.
