Naming a child is hard enough. Now, imagine you’ve just been elected to lead a global institution with over a billion followers, and you have about ten minutes to pick the name that will define your entire legacy. No pressure, right? Since the middle of the 20th century, the names of popes since 1940 have shifted from a rigid adherence to tradition to some pretty surprising, even radical, choices. It’s not just about a favorite saint or a cool-sounding Latin word. It is a political manifesto wrapped in a single word.
Think about it.
When Cardinal Eugenio Pacelli stepped onto the balcony in 1939, right on the cusp of the decade that would change everything, he chose Pius XII. He was leaning into continuity. But by the time we get to the current era, the naming conventions have been blown wide open. We went from a long line of Piuses and Benedicts to a guy naming himself after a beggar-saint from Assisi.
The Era of the "Pious" Continuity
Pius XII is a name that carries a lot of weight, and honestly, a lot of baggage. He reigned from 1939 to 1958. By choosing "Pius," he was signaling that he intended to follow the path of his predecessor, Pius XI. It was a safe bet in a world that was about to fall apart. You have to realize that in the Vatican, names are like a shorthand for a specific brand of theology. The "Pius" line was generally associated with a more centralized, traditionalist, and somewhat legally-minded papacy.
Pacelli was a diplomat. He knew that by keeping the name Pius, he was projecting stability while Europe was literally catching fire. He was the last in a long, almost unbroken chain of that specific name.
Then came the curveball.
When John XXIII Broke the Pattern
In 1958, everyone expected another "Pius" or maybe a "Benedict." Instead, Angelo Roncalli chose John. People were genuinely confused. You see, there hadn't been a Pope John in over 500 years. The last one, John XXIII (the first one), was actually an "antipope" during the Western Schism, which made the name sort of radioactive in Catholic circles.
By picking John XXIII, Roncalli was effectively "cleaning" the name and signaling a fresh start. He wasn't interested in the rigid, aristocratic vibe of the Piuses. He was "Good Pope John." He wanted to open the windows of the Church. This choice paved the way for the Second Vatican Council, arguably the most significant religious event of the 20th century.

The Birth of the Double Name: John Paul
If you were alive in the 60s and 70s, you saw the papacy try to balance two worlds. Paul VI (1963–1978) chose his name to honor the Great Apostle, signaling an era of global travel and outward-facing mission. But it’s what happened in 1978 that really messed with the history books.
1978 is known as the "Year of Three Popes."
Albino Luciani became John Paul I. This was the first time in history a pope had used a double name. It wasn't just a stylistic choice; it was a tribute to his two predecessors, John XXIII and Paul VI. He wanted to bridge the gap between the progressive "John" fans and the more moderate "Paul" supporters. He only lasted 33 days.
Then came Karol Wojtyła.
When the Polish cardinal was elected, he took the name John Paul II to honor the man who had just died so suddenly. He kept that name for 26 years. Because of his massive global presence, the name "John Paul" became synonymous with the papacy for an entire generation. Honestly, most kids growing up in the 80s and 90s probably thought "John Paul" was just the title you took when you got the job, like "President" or "CEO."
Benedict and the Return to Roots
When Joseph Ratzinger was elected in 2005, he pivoted hard. He didn't become John Paul III. He chose Benedict XVI.

Benedict XV was the "Pope of Peace" during World War I. Ratzinger wanted to evoke that spirit during a time of global conflict. He also wanted to link back to St. Benedict of Nursia, the father of Western monasticism. It was a signal that he wanted to focus on the Christian roots of Europe. It was a scholarly name. A quiet name. It was a complete departure from the "Rock Star" energy of the John Paul years.
Francis: The Ultimate Disrupter
Then we get to 2013. Jorge Mario Bergoglio did something that hadn't been done since the year 913. He chose a completely new name.
Francis.
No Roman numeral. Just Francis.
He didn't name himself after a previous pope. He named himself after St. Francis of Assisi, the man of the poor, the man of peace, the man who loved creation. This was a massive shift in the names of popes since 1940. By skipping the traditional papal names, he was saying that the institution needed to stop looking at its own history and start looking at the world's problems.
The choice of Francis was a "programmatic" name. It told you exactly what his papacy was going to be about before he even finished his first speech. He was choosing the periphery over the center. It’s kinda wild when you think about how much power a single word holds in that context.
Why Do These Names Matter to Us?
You might think this is just ecclesiastical trivia. It’s not. The naming process reflects how an ancient institution views its role in the modern world.

- Pius XII represented the old guard and the struggle of the World War II era.
- John XXIII and Paul VI represented the "Aggiornamento" or the bringing-up-to-date of the Church.
- John Paul II was the global communicator.
- Benedict XVI was the intellectual conservator.
- Francis is the social reformer.
Each name is a data point in a 2,000-year-old conversation. If you look at the trajectory of the names of popes since 1940, you see a move away from "dynastic" naming (where you just pick the next number in a sequence) toward "thematic" naming.
Actionable Insights for the History Buff
If you’re researching this topic or just curious about how these naming conventions work, here’s how to look at the data more deeply.
First, check the "Regnal Name" versus the "Birth Name." The contrast is usually where the story is. For example, a "Leo" is usually interested in social justice and labor rights, thanks to Leo XIII. A "Pius" is almost always a sign of traditionalism.
Second, look at the gaps. The fact that we haven't had a "Pius XIII" tells you more about the current state of the Catholic Church than any official document could. It suggests that the specific brand of 19th and early 20th-century traditionalism associated with that name is currently out of favor in the Vatican's inner circles.
Third, pay attention to the "firsts." John Paul I was the first double name. Francis was the first Francis. These aren't accidents. They are deliberate breaks from the status quo.
If you're ever in a position to name something—a business, a kid, a pet, or a papal legacy—remember that names carry the ghosts of everyone who used them before. The Popes certainly do.
To dig deeper into this, you should look up the "Annuario Pontificio." It’s the official Vatican directory. It lists every pope in history, and you can see the clusters where certain names dominate during specific centuries. You’ll notice that since 1940, the variety has actually slowed down, even as the meanings behind the names have become more intense and politically charged.
Keep an eye on the next Conclave. The name the next guy picks will tell you everything you need to know about the next twenty years of church history before he even says "Hello."
