Sigismund and the Council of Constance
Hello, this is Kori.
When we look back at medieval Europe, there are moments that feel almost unbelievable.
Today, I want to take you into one of those moments — a time when the Christian world had not one, not two, but three popes.
Yes, three.
A World Where Even Faith Was Divided
Imagine this for a second.
You’re a farmer in 15th-century Europe.
You wake up on a Sunday, walk to church, and ask a simple question:
“Who is the real pope?”
And the answer?
“It depends.”
One in Rome.
One in Avignon.
And eventually… another one in Pisa.
For people whose entire lives revolved around religion, this wasn’t just confusing — it was terrifying.
If the Church itself was divided, what truth could anyone trust?
This crisis became known as the Western Schism.
The Roots of Chaos: The Avignon Papacy
To understand how things spiraled out of control, we need to go back a bit.
In the early 14th century, the papacy moved from Rome to Avignon in southern France.
For nearly 70 years, the popes were heavily influenced by the French crown.
When Pope Gregory XI finally returned to Rome in 1377, it seemed like stability would return.
But then he died.
And everything collapsed.
At the root of all this turmoil stood one powerful figure.
That figure was Philip IV of France | The Avignon Captivity and the Fall of Papal Power
By directly challenging the pope and relocating the papacy to France,
he created the first major crack in the authority of the medieval Church.
Two Popes… Then Three
Under pressure from Roman citizens, an Italian pope — Urban VI — was elected.
But French cardinals rejected him, claiming the election was invalid.
They elected their own pope, Clement VII, in Avignon.
Europe split into two camps.
| Faction | Pope | Supported By |
|---|---|---|
| Rome | Urban VI | England, Holy Roman Empire |
| Avignon | Clement VII | France, Scotland, Spain |
Then came the worst move of all.
The Council of Pisa (1409)
Leaders tried to fix the problem by deposing both popes and electing a new one.
But the original two refused to step down.
Now there were three popes.
Sigismund Enters the Stage
At this point, Europe wasn’t just divided — it was paralyzed.
This is where Emperor Sigismund comes in.
He wasn’t just acting out of religious concern.
He had a bigger problem.
The Ottoman Threat
After suffering a devastating defeat at the Battle of Nicopolis (1396), Sigismund knew:
Europe needed unity to survive.
No unity → No crusade
No crusade → Ottoman expansion continues
So fixing the Church wasn’t optional.
It was strategic.
The Council of Constance Begins (1414)
Sigismund pressured Pope John XXIII (the Pisa pope) to call a new council.
Location: Constance (modern-day Germany)
What followed was one of the largest international gatherings of the medieval world.
Thousands attended:
- Cardinals
- Bishops
- Kings
- Diplomats
- Merchants
It was basically a medieval version of a global summit.
The Turning Point: Authority Shift
One radical idea changed everything:
Conciliarism — the belief that a council has more authority than the pope.
The council declared:
Even the pope must obey the council.
That was revolutionary.
The Great Collapse of the Three Popes
Here’s how the three-popes problem ended:
| Faction | Pope | Outcome |
|---|---|---|
| Rome | Gregory XII | Voluntarily resigned |
| Avignon | Benedict XIII | Refused → Deposed |
| Pisa | John XXIII | Fled → Captured & removed |
Suddenly, all three were gone.
For the first time in decades, the seat of power was empty.
The Escape of Pope John XXIII
One of the most dramatic moments?
John XXIII literally fled the council disguised as a messenger.
Yes… the pope ran away.
But Sigismund didn’t let the council collapse.
He used military force to hold everything together.
That moment alone shows who was really in charge.
The Tragedy of Jan Hus
But the council wasn’t just about unity.
It also dealt with “heresy.”
Enter Jan Hus — a reformer who criticized corruption in the Church.
Sigismund promised him safe passage.
But once Hus arrived…
He was arrested.
And in 1415, he was burned at the stake.
Why This Matters
This wasn’t just an execution.
It triggered:
- Massive outrage in Bohemia
- The Hussite Wars
- Long-term instability for Sigismund himself
In many ways, Hus became the precursor to the Protestant Reformation.
The Final Resolution: One Pope Again
In 1417, a new pope was elected:
Martin V
For the first time in nearly 40 years, Europe had a single pope again.
The Western Schism was over.
What Changed After the Council?
This wasn’t just a religious fix.
It was a major shift in power.
Before:
- Pope = supreme authority
After:
- Councils + political rulers gained influence
Sigismund emerged as:
- Mediator of Europe
- Defender of Christendom
- Political strategist
Key Takeaways
- The Western Schism wasn’t just religious — it was political
- The Council of Constance restored unity but at a cost
- Sigismund used diplomacy, pressure, and force effectively
- Jan Hus’ death planted seeds for future religious reform
Kori’s Thought
When you really sit with this story, it hits differently.
Sigismund unified the Church — a huge achievement.
But he did it while allowing an innocent man to burn.
History rarely gives us pure heroes or villains.
It gives us people making impossible choices.
And honestly…
that feels a lot like today, doesn’t it?

As the Council of Constance brought an end to the division within the Church,
a different kind of power shift was quietly unfolding across Europe.
To fully understand this moment, we need to step back and look at a broader theme:
“Rulers of Medieval Europe: The Clash and Evolution of Holy Roman Emperors and English Kings ”
While the Holy Roman Emperor continued to claim universal authority over Christendom,
emerging kingdoms like England were strengthening their own centralized and independent power.
This growing tension between imperial unity and national sovereignty
marked the limits of the medieval order
and signaled the beginning of Europe’s transition toward modern states.
Sigismund and the Council of Constance Q&A
Q1. What caused the Western Schism?
The conflict began after the papacy returned from Avignon to Rome. Disputes over legitimacy led to rival popes in different regions.
Q2. Why did the Council of Pisa fail?
Because the original popes refused to step down, creating a third pope instead of resolving the conflict.
Q3. Why didn’t Sigismund save Jan Hus?
He prioritized the success of the council and Church unity over Hus’ safety, leading to a political compromise.
