France was once the undisputed center of the world, or at least that’s how Louis XIV saw it from his gold-leafed bedroom at Versailles. But in October 1685, he made a choice that historians still scratch their heads over. He signed the Edict of Fontainebleau. You might know it better as the Edict of Nantes revocation, a single piece of parchment that effectively told roughly 800,000 of France’s most productive citizens to either convert to Catholicism or get out. Most of them chose to leave. It was a massive "brain drain" before that term even existed.
Honestly, the fallout was catastrophic. Imagine losing your best engineers, your most skilled silk weavers, and your most disciplined soldiers all in a single decade. That is exactly what happened to 17th-century France.
Why Louis XIV Actually Did It
We like to think of kings as having master plans. Sometimes they just have massive egos and bad advice. By the 1680s, Louis XIV—the "Sun King"—was obsessed with the idea of un roi, une loi, une foi (one king, one law, one faith). He felt that having a Protestant minority, the Huguenots, was a personal insult to his absolute power. It wasn't just about religion; it was about total control.
He’d been tightening the screws for years. First, they banned Huguenots from government jobs. Then, they started the dragonnades. This was a particularly nasty tactic where the state would literally force Protestant families to house rowdy, violent soldiers (dragoons) who were encouraged to make life a living hell until the family converted.
The king was told that almost everyone had already converted because of these pressures. His advisors, particularly the Marquis de Louvois and maybe even his second wife, Madame de Maintenon, gave him a skewed version of reality. They told him the Huguenots were gone. So, he figured, why not just make it official? He signed the Edict of Nantes revocation thinking it was the final stroke of a pen on a problem that was already solved. He was wrong.
The Great Escape: A 17th-Century Refugee Crisis
Protestants weren't technically allowed to leave France under the new law. If you were caught trying to flee, the men were sent to be galley slaves and the women were imprisoned. Yet, people fled by the thousands. They hid in coal ships. They dressed as peasants. They hiked across the Jura Mountains into Switzerland.

It’s estimated that between 200,000 and 300,000 people escaped. This wasn't just a loss of people; it was a massive transfer of wealth and intellect. The Huguenots took their secrets with them.
Where the Talent Went
The map of Europe literally changed because of this migration. Berlin, which was a backwater swamp at the time, welcomed the French refugees with open arms. The Great Elector of Prussia issued the Edict of Potsdam just weeks after the French move, basically saying, "If France doesn't want you, we do." Within a few years, one-third of Berlin’s population was French. They brought with them the secrets of high-end manufacturing that Prussia desperately needed.
London saw a similar boom. The Spitalfields district became a global hub for silk weaving. In the Netherlands, the publishing industry exploded because all the French thinkers who were censored at home moved to Amsterdam to print their books. Even the fledgling colonies in South Africa and North America (like New Rochelle in New York or Charleston in South Carolina) felt the impact.
The Economic Suicide of the Sun King
If you look at the numbers, the Edict of Nantes revocation was a self-inflicted wound. France was already struggling with the costs of Louis's endless wars. By kicking out the Huguenots, he removed the very people who were paying the taxes to fund those wars.
The Huguenots were the "middle class" of their day. They weren't the landed gentry who sat around waiting for rent; they were the doers. They ran the maritime trade in La Rochelle. They managed the banking systems. When they left, the French economy didn't just stumble; it stalled. Meanwhile, France's greatest rivals—England and the Dutch Republic—were essentially handed a free "tech tree" upgrade by their biggest enemy.

Historian Scoville has pointed out that while the economic impact wasn't the sole reason for France's later decline, it certainly accelerated it. You can't lose your most literate and skilled demographic and expect things to stay the same.
What Most People Get Wrong About the Revocation
A common myth is that this was a popular move. In reality, while some Catholics celebrated, many French merchants were horrified. They saw their business partners disappearing overnight. Even some members of the Catholic clergy, like the famous military engineer Vauban, thought it was a disaster. Vauban actually wrote a bold memo to the King suggesting that the revocation was ruining the country’s prestige and economy. Louis, unsurprisingly, ignored him.
Another misconception is that it "fixed" the religious divide. It didn't. It just pushed it underground. The Camisard Rebellion in the early 1700s saw French Protestants in the Cévennes mountains waging a bloody guerrilla war against the crown. It was a distraction the French military didn't need while they were fighting the War of the Spanish Succession.
Long-Term Scars on French History
The Edict of Nantes revocation set a precedent for intolerance that would haunt France for a century. It created a deep-seated resentment toward the monarchy and the Church that eventually boiled over during the French Revolution in 1789. Many of the Enlightenment thinkers, like Voltaire, used the story of Huguenot persecution as a primary weapon against organized religion and absolute monarchy.
Basically, Louis XIV tried to create unity through force, but he ended up creating the very fractures that would eventually bring down the House of Bourbon.

Real-World Lessons from 1685
History isn't just about dusty dates. The story of 1685 is a case study in what happens when ideology overrides economic reality.
- Human Capital is Mobile: If you make your country inhospitable to certain groups, they will take their talents elsewhere. Your loss becomes your competitor's gain.
- Echo Chambers are Dangerous: Louis XIV lived in a bubble. His advisors told him what he wanted to hear (that the Huguenots were gone), leading to one of the biggest policy blunders in European history.
- Religious Freedom is Economic Freedom: Countries that practiced relative tolerance during this era, like the Dutch Republic, consistently outperformed those that enforced strict religious conformity.
How to Explore This History Further
If you want to see the physical legacy of this event, don't just go to Versailles. Go to the Huguenot Museum in Rochester, UK, or visit the "French Quarter" in Berlin (Friedrichstadt). You can still see the French influence in the architecture and even the surnames of the people living there.
For those researching their own ancestry, the Huguenot Society of Great Britain and Ireland maintains incredible records of the families that fled. Because the refugees were often literate and well-documented, it is surprisingly easy to trace these lineages back to specific French provinces.
When you're looking at the Edict of Nantes revocation, don't just see it as a religious conflict. See it as a moment when a superpower decided that conformity was more important than prosperity—and paid the price for the next hundred years.
To truly understand the impact, look at the trade balances of 18th-century Europe. You'll find that France’s loss of the luxury goods market was almost directly proportional to the rise of British and Prussian manufacturing. If you're a history buff or an economics student, studying the specific industries that moved—like clockmaking, lens grinding, and lace production—provides a granular look at how migration drives innovation. Start by looking into the "Refugee Records" available through the French Protestant Church of London; they offer a raw, human look at the people who risked everything to escape the Sun King's reach.
