History isn't usually a clean-cut affair of heroes and villains. Honestly, it’s mostly a messy pile of "it depends" and "what were they thinking?" When you talk about Leopold III of Belgium, you’re stepping right into one of the biggest political minefields of the 20th century. To some, he was a stoic leader who stayed with his people during their darkest hour. To others? He was the man who betrayed the Allies, ignored his own government, and basically handed his country to the Nazis on a silver platter.
The "Royal Question." That’s what they call the years-long drama that followed his actions during World War II. It wasn't just a polite debate in a classroom; it almost sparked a civil war. We’re talking about strikes, riots, and a country literally split down the middle between the Dutch-speaking north and the French-speaking south.
The Eighteen-Day Fall of Belgium
Let’s get the facts straight about May 1940. It was chaos. The German Blitzkrieg was tearing through Western Europe, and Belgium was right in the crosshairs. Leopold III had already made waves by insisting on a policy of "armed neutrality" before the war. Basically, he didn't want to side with France or Britain too early, hoping to keep Belgium out of the fight.
It didn't work.
When the Nazis invaded on May 10, the Belgian army fought hard, but they were hopelessly outmatched. By May 25, the situation was dire. Leopold met with his ministers at the Kasteel van Wijnendale. This is where things got ugly. His ministers—including Prime Minister Hubert Pierlot—begged him to flee to London. They wanted to set up a government-in-exile, just like the Dutch and Norwegian royals did.
Leopold said no.
"I have decided to stay," he told them. He believed the Allied cause was lost and that leaving would make him look like a deserter. He wanted to share the fate of his soldiers. Three days later, on May 28, 1940, he surrendered unconditionally.

Traitor or Prisoner?
The backlash was instant. Winston Churchill was livid, calling the surrender a "pitiful episode" that exposed the Allied flank. In Paris, refugees threw stones at statues of his father, the beloved King Albert I.
But inside Belgium? The story was different.
For the first few years of the occupation, many Belgians actually respected him for staying. He was technically a prisoner of war at Laeken Castle, and he used his position to write to Hitler, which some historians, like those at Britannica, credit with saving about 500,000 Belgian women and children from being deported to German munitions factories.
But then he made a move that even his supporters struggled to defend. In 1941, while his country was starving and under Nazi boots, he got married.
The Secret Marriage That Changed Everything
Leopold’s first wife, Queen Astrid, had been the "Diana" of her time—beautiful, kind, and tragically killed in a car accident in 1935. The nation was still mourning her. So, when it leaked that Leopold had secretly married a commoner named Lilian Baels in a religious ceremony (without the government’s permission, which was unconstitutional), the public mood shifted.
It felt like a slap in the face.

The fact that the marriage happened while he was supposed to be a "prisoner" made it worse. People started asking: "If he's a prisoner of war, how does he have time for a royal wedding?" The optics were terrible. Lilian was never given the title of Queen—she was the Princess de Réthy—but the damage was done.
The Royal Question Explodes
After the war ended in 1945, Leopold couldn't just walk back onto the throne. He was stuck in Switzerland while his brother, Prince Charles, acted as regent. The country was paralyzed.
- The Flemish (North): Mostly supported Leopold. They saw him as a victim of smear campaigns.
- The Walloons (South): Mostly hated him. They saw his surrender as a betrayal of the French-speaking resistance.
- The Socialists and Liberals: Demanded his abdication, fearing he had authoritarian tendencies.
In 1950, they finally held a referendum. Leopold won with about 57% of the vote. In any other election, that’s a clear win. But in a monarchy meant to symbolize unity? It was a disaster. The "Yes" votes came mostly from Flanders, while Wallonia screamed "No."
When Leopold finally returned to Brussels on July 22, 1950, the country went into meltdown. General strikes paralyzed the economy. In Liège, three protesters were shot dead by police. It looked like Belgium was about to tear itself apart.
The Abdication and the "Diarchy"
Leopold realized he couldn't stay. On August 1, 1950, he agreed to hand over his powers to his son, Baudouin. He officially abdicated a year later.
But he didn't exactly go away.

For years, Leopold and Lilian stayed at the royal palace, reportedly exerting a huge amount of influence over the young King Baudouin. Historians often refer to this period as a "diarchy"—a two-headed monarchy. It wasn't until Baudouin married Fabiola in 1960 that Leopold finally moved out and turned his attention to his other passions: travel, social anthropology, and entomology.
Believe it or not, there are actually two species of reptiles named after him: Gehyra leopoldi and Polemon leopoldi.
What We Can Learn from Leopold III
Looking back, Leopold III was a man who seemed to value his personal sense of duty over the political realities of a constitutional monarchy. He thought he was being a leader by staying with his troops, but he forgot that a King isn't just a soldier—he's a symbol of the state. When that symbol becomes a source of division, the institution itself is at risk.
If you’re interested in diving deeper into this era, there are a few things you can do to get the full picture:
- Visit the Kasteel van Wijnendale: This is the actual spot where the 1940 confrontation happened. It’s a preserved historical site in West Flanders.
- Read "Leopold III and the Belgian Royal Question": This book by E. Ramón Arango is one of the most cited works for understanding the constitutional nuances of the crisis.
- Check out the Royal Museum of the Armed Forces and Military History in Brussels: They have extensive exhibits on the 18 Days' Campaign and the Belgian Resistance.
The story of Leopold III of Belgium is a reminder that in politics, being "right" in your own mind isn't the same as being right for the people you lead. His reign ended in 1951, but the linguistic and cultural divisions he inadvertently widened are still a major part of Belgian life today.
