How Spain's Catholic Monarchs turned religious enforcement into a state weapon that prosecuted 150,000 people over centuries.
[INTRO]
ALEX: The Spanish Inquisition executed far fewer people than you'd think — maybe 3,000 to 5,000 over its entire existence. But here's the twist: execution wasn't the point. The real weapon was confiscation — seizing everything you owned, your home, your wealth, your future.
JORDAN: Wait, so this was basically a profit-driven shakedown dressed up as religious purity?
ALEX: Exactly. And it started as a tool to control people who had just been forced to convert to Christianity. Today, we're unpacking how the Spanish Inquisition became one of history's most effective instruments of state terror.
[CHAPTER 1 - ORIGIN]
ALEX: In 1478, Pope Sixtus IV authorized King Ferdinand and Queen Isabella of Spain to establish their own Inquisition. The first inquisitors, Miguel de Morillo and Juan de San Martín, got to work in 1480. Officially, their job was maintaining Christian orthodoxy — rooting out heresy.
JORDAN: But Spain already had an Inquisition, right? The medieval one run by the Pope?
ALEX: Yes, and that's the key. The Catholic Monarchs wanted their own version, one they controlled, not the Pope. This wasn't just about faith — it was about consolidating royal power. By taking religious enforcement into their own hands, Ferdinand and Isabella created a parallel justice system that answered only to them.
JORDAN: So the Church gave them a weapon, and they pointed it wherever they wanted?
ALEX: Precisely. And their first targets were conversos — Jews who had converted to Christianity. Spain's rulers didn't trust these conversions. They suspected many converts were secretly practicing Judaism, and the Inquisition gave them legal cover to investigate, interrogate, and punish.
JORDAN: But why the obsession with conversos specifically?
ALEX: Because in 1492, Ferdinand and Isabella issued a decree: all Jews had to convert to Catholicism, leave Spain, or face death. An estimated 40,000 to 100,000 Jews were expelled that year. The ones who stayed and converted became immediate suspects. The Inquisition treated conversion itself as evidence of possible fraud.
[CHAPTER 2 - CORE STORY]
ALEX: Over the next few centuries, the Inquisition prosecuted around 150,000 people. Conversos and moriscos — Muslims who had converted — bore the brunt early on. A second decree in 1502 forced Muslims to convert or leave, creating another wave of suspects.
JORDAN: And what happened to people the Inquisition arrested?
ALEX: Punishments ranged wildly. Some faced public penance or flogging. Others were exiled, sentenced to galley slavery, or imprisoned for years — sometimes for life. But the most devastating punishment wasn't physical. Historian Joseph Pérez argues the profit motive drove much of this: the Inquisition confiscated all property from the accused.
JORDAN: So even if you weren't executed, you were financially destroyed.
ALEX: Right. Your family lost everything. And this is where it gets darker: Spain introduced limpieza de sangre — blood purity statutes. These laws created a racial hierarchy, barring anyone with Jewish or Muslim ancestry from holding certain jobs or titles. This was Europe's first codified system of racial discrimination, and it lasted into the 19th and 20th centuries.
JORDAN: Wait, this wasn't just religious anymore — it became racist?
ALEX: Exactly. Even if you converted sincerely, your bloodline marked you. The Inquisition expanded its targets over time, too. It went after Protestants during the Reformation, people accused of witchcraft, alumbrados — mystics the Church found threatening — and even Freemasons. Charges included blasphemy, bigamy, sodomy, basically anything the state wanted to criminalize.
JORDAN: How did they actually carry out these punishments?
ALEX: Through the auto-da-fe — the act of faith. These were massive public spectacles. The accused were paraded through the streets, their sentences read aloud, confessions extracted or announced. Then the guilty were handed over to civil authorities for execution, usually burning at the stake. The Inquisition technically didn't kill anyone — it just condemned them and let the state do the deed.
JORDAN: That's a convenient loophole.
ALEX: Very. And the Inquisition didn't stay in Spain. It spread to Spanish-controlled Southern Italy, to the Americas, anywhere the crown held power. For over three centuries, it operated as both religious police and political weapon.
[CHAPTER 3 - WHY IT MATTERS]
ALEX: The Spanish Inquisition wasn't abolished until the 19th century, but its legacy runs deeper than its timeline. It engineered mass expulsions, hundreds of thousands of forced conversions, and introduced systemic racism into European law.
JORDAN: And it set a template, right? For how states could weaponize religion?
ALEX: Absolutely. It showed how a government could take a moral cause — defending the faith — and twist it into a tool for control, profit, and persecution. The Inquisition normalized surveillance, encouraged denunciations, and made fear a governing strategy. Those tactics didn't die with it.
JORDAN: What about the phrase 'Nobody expects the Spanish Inquisition'? Where does that come from?
ALEX: That's Monty Python, 1970s comedy. But the joke works because the Inquisition became shorthand for sudden, arbitrary cruelty. In reality, people absolutely expected it — that was the point. The fear kept everyone in line.
[OUTRO]
JORDAN: Okay, so what's the one thing to remember about the Spanish Inquisition?
ALEX: It wasn't about saving souls — it was about seizing power, wealth, and control under the cover of religious purity.
