When you think of the Spanish Inquisition, you probably picture dark robes, secret chambers, and endless flames. The truth is even more chilling: although popular myth inflates the death toll into the hundreds of thousands or even millions, historians agree the actual number of executions hovers between 3,000 and 5,000. Still, those figures represent a terrifying institution that spared no one – not even children or entire families. Below, we dive into the top 10 disturbing stories that reveal just how ruthless the Inquisition could be.
Why These Top 10 Disturbing Stories Matter
10 Ines Esteban
In the spring of 1499 a startling figure emerged from the modest village of Herrera del Duque: a ten‑year‑old girl named Ines Esteban who proclaimed herself a prophet. She announced that the Messiah would descend to Earth the following year, rescuing the persecuted conversos – Jews forced to adopt Christianity – and ushering them to a promised sanctuary.
Ines’s bold proclamations ignited hope among the oppressed converso community. Children and adults flocked to hear her, and many began to revive Jewish customs such as Sabbath observance and adherence to Mosaic law. The anticipated arrival of the Messiah was slated for March 8, 1500, and the entire town waited with bated breath.
The Inquisition, however, could not tolerate such open defiance. Within a month of the missed prophecy, Ines was seized, hauled to Toledo, and detained from May through July of 1500. Though still a child, the inquisitors showed no mercy; they condemned her to the stake, and the young prophet met a fiery end.
9 Diego Rodriguez Lucero
From 1499 to 1506 the city of Córdoba fell under the iron grip of inquisitor Diego Rodriguez Lucero, infamously dubbed “the bringer of darkness.” Lucero’s reign was marked by grotesque personal vendettas, including sending a man named Julian Trigueros to the flames simply to claim his wife, and murdering the parents and husband of one of his own mistresses.
Lucero’s cruelty knew no bounds; whether the accused were conversos, peasants, or nobles, he employed torture and intimidation to extract confessions and never hesitated to sentence anyone to the stake. In June 1506 alone, he ordered a staggering 100 death sentences.
Eventually, the citizens of Córdoba grew weary of his terror. A marquis mustered an army, stormed Lucero’s prison, and liberated the captives. Lucero escaped, but the scandal of his atrocities reached the Grand Inquisitor, who ordered his arrest in 1908. Though briefly detained, Lucero was released and died in Seville later that year.
8 William Lithgow
In 1620 the Scottish traveler William Lithgow found himself in the port city of Málaga, where inquisitors, suspecting him of espionage for England, arrested him. Though they uncovered no concrete evidence, the inquisitors admitted his innocence yet chose to keep him imprisoned because his writings criticized Catholic doctrine.
Accused of heresy, Lithgow endured brutal torture and severe starvation. Remarkably, two slaves – one Black, one Muslim – slipped him food, keeping him alive just enough to refuse recantation. The inquisitors eventually sentenced him to be burned at the stake.
Fate intervened when the governor of Málaga stepped in at the last moment, ordering Lithgow’s release and safe passage back to England. The ordeal left him with a permanently disabled left arm, but he survived and later chronicled his travels, providing a vivid first‑hand account of his terrifying ordeal.
7 Joseph Perez
While the Spanish Inquisition is best known for quashing heresy, it also prosecuted other offenses, such as sodomy, especially in the Kingdom of Aragon. By the early 17th century, the Inquisition had conducted nearly a thousand trials related to sodomy, initially treating it as a capital crime.One of the victims of these brutal proceedings was university professor Joseph Perez. Arrested in 1613 on accusations of making advances toward two of his students, Perez was initially slated for a fine and exile. However, while incarcerated he spiraled into madness, prompting the Inquisition to assign him a physician.
In a fateful conversation with his appointed lawyer, Perez confessed that the accusations were true and even claimed to have engaged in sexual acts with his doctor while in jail. The attorney, acting as the Inquisition’s official legal representative, reported the confession, sealing Perez’s fate: both he and the doctor were sentenced to death.
6 Pedro de Arbues
The Inquisition was established in Aragon in 1484, but the affluent converso community soon plotted against it. After inquisitor Gaspar Juglar’s sudden death – rumored to be the work of poisoned conversos – a year later a group of conspirators plotted to kill another inquisitor, Pedro de Arbues.
In September 1485, Arbues fell victim to a coordinated attack inside a cathedral, where assassins slashed his throat. The murder sparked outrage, prompting the Inquisition to launch a massive crackdown: hundreds were arrested, many conspirators were executed, one man beheaded with his head displayed on a pole, while others suffered hand amputation before being decapitated and quartered.
Ironically, before Arbues’s murder many Aragonese already despised the Inquisition. The conspirators hoped to weaken the fledgling institution, but the brutal retaliation only cemented its power and public acceptance.
5 Ana de Castro
In 1707 the strikingly beautiful Ana de Castro set sail from Spain with her husband, eventually establishing herself in Lima, Peru. Though initially struggling, her charm and a second marriage soon made her one of the city’s wealthiest and most socially prominent women.
Castro’s beauty attracted many suitors, and in 1726 a jealous rival orchestrated a plot to ruin her reputation. He bribed a maid to hide a crucifix beneath Castro’s mattress, then reported to the Inquisition that she had been caught with the sacred object, implying blasphemy.
The Inquisition seized her assets, imprisoned her for over a decade, and subjected her to three rounds of torture. Accused of secretly practicing Judaism—a “Judaizer”—she pleaded repentance, which under the law should have spared her life. Nevertheless, she was executed in December 1736, her tragic fate a stark reminder of the era’s intolerance.
4 The Bohorques Sisters
Maria de Bohorques, a bright young woman from Seville, was fluent in Greek and Latin and immersed herself in Lutheran literature. When the Inquisition interrogated her, she openly admitted that Lutheranism held truth for her, a confession that sealed her doom.
Before Maria’s execution, she warned her sister Jane that she bore no ill will toward the inquisitors. Despite being six months pregnant, Jane was arrested solely on Maria’s confession, with no additional evidence. While incarcerated, Jane gave birth, only to see her newborn taken away after eight harrowing days.
Jane endured relentless torture, bound with cords until she bled from her mouth. She succumbed to her injuries shortly after, and on the very day of her death the Inquisition paradoxically declared her innocent, a bitter irony that underscored the institution’s capricious cruelty.
3 The Carabajal Family
In 1580 Portuguese-born Luis de Carabajal y Cueva led a wave of settlers to Mexico, founding a colony in what is now Nuevo León. Among the colonists were his sister, Francisca Nunez de Carabajal, her husband, and eight children, who later relocated to Mexico City.
Life seemed prosperous until 1590, when the Inquisition abruptly arrested the entire Carabajal family on accusations of secretly practicing Judaism. Under brutal torture, the family fractured: Francisca confessed that her husband and children were guilty, while her son Luis Jr. turned on his mother, testifying against her and his siblings.
In December 1596, Francisca and five of her children were burned at the stake. Her husband died before the execution, while son Baltasar escaped by fleeing the city. Daughter Mariana met the same fiery fate six years later. Only the youngest two, Anica and Miguel, survived the ordeal.
2 The Holy Child Of La Guardia
In the summer of 1490, two Jews and six conversos were seized by the Inquisition on the bizarre charge of murdering a Christian boy near the town of La Guardia. One of the accused, Juce Franco, absurdly confessed that he and his companions had crucified the boy in a cave, torn out his heart, and drained his blood.
The remaining prisoners offered wildly conflicting testimonies: they could not agree on the date, the victim’s name, or even the location of the alleged murder. No missing child was reported, and the supposed burial site yielded no corpse.
Rather than acquit the men for lack of evidence, the Inquisition deemed them liars and sentenced them to the stake. The fictional victim was later venerated as a folk saint, the Holy Child of La Guardia, and astonishingly, some locals continue to honor his supposed martyrdom even in the 21st century.
1 Cayetano Ripoll
By the 18th century, the Spanish Inquisition was waning. The Bourbon reforms, coupled with Enlightenment skepticism, eroded its authority, leaving only a handful of executions in the entire century.
The final victim of this dying institution was Cayetano Ripoll, a deist teacher accused of neglecting his students’ religious instruction. After two years of imprisonment, he was sentenced to death and, in July 1826, hanged for heresy. Post‑mortem, his body was placed in a barrel painted with flames, symbolizing a fiery condemnation.
Ripoll’s execution sparked outrage across Europe, highlighting the anachronistic cruelty of a fading Inquisition. Although the tribunal had been abolished, revived, and finally abolished again in 1834 by Queen Maria Christina, this grim episode remains a stark reminder of the institution’s lingering darkness.
