When the Knights of St. John settled in Malta, they built a fortress of faith and military might. But beneath the gleaming bastions lay a brutal economy powered by enslaved labour. This episode uncovers the slave market in Valletta's Piazza degli Schiavi, the bagnio prison holding thousands, and the 1749 conspiracy in which slaves nearly seized the island. We explore the moral contradictions of the Order as both defenders of Christendom and traders in human flesh, and how this dark legacy shaped Malta's society and wealth. Learn about the corso privateering network, the everyday lives of slaves, and the eventual decline of the trade.

## Transcript

Lucas: You know, when we talk about the Knights of St. John on Malta, we usually focus on the heroic defence during the Great Siege, or the magnificent Sacre Infermeria. But there's a much darker side to their story, one that's often left out of the romanticised image.
Luna: The slave market, right? I've heard that Valletta had a major slave trade.
Lucas: Exactly. From the moment the Knights took possession of Malta in 1530, the economy of the island became heavily dependent on slave labour. The Knights themselves were not just warrior monks — they were also corsairs. The corso, their sanctioned privateering, was one of the main sources of income for the Order.
Lucas: And corsair raids meant captives. Thousands of Muslim men, women, and children were brought to Malta and sold in the slave market. The market itself was located in the heart of Valletta, in a square called the Piazza degli Schiavi — literally 'the Square of the Slaves'.
Luna: So it was a public, everyday part of life, not hidden away.
Lucas: Exactly. The slave market was a bustling hub. Slaves were auctioned off, often with families separated. And the numbers are staggering. At its peak in the 17th and early 18th centuries, Malta had a slave population of around 2,000 at any given time — on an island with a free population of maybe 50,000. That's a higher proportion of slaves than in most American colonies.
Lucas: These slaves were housed in a special building called the bagnio, just behind the Sacre Infermeria. It was essentially a prison that could hold up to 2,500 people, with cells and workshops. Slaves were used for hard labour on the fortifications, in the shipyards, and even in the hospital itself.
Luna: Wait, the Sacre Infermeria — the great hospital — used slave labour?
Lucas: Yes. The hospital employed slaves as orderlies, cooks, and cleaners. It's one of those uncomfortable facts that jar with the image of the merciful knights. But the Order's view was pragmatic: slaves were a resource, and the hospital was a place of healing, so why not use them? The moral contradiction was rarely questioned.
Lucas: However, that contradiction occasionally exploded into violence. The most dramatic episode was the Conspiracy of the Slaves in 1749. A group of Ottoman slaves, led by a man named Suleiman, plotted a mass uprising to seize the island. They planned to kill the Grand Master and the leadership, then open the gates for an Ottoman fleet.
Luna: Was it an inside job? Did they have help from outside?
Lucas: They did have some help. A Maltese priest, disillusioned with the Order, acted as an intermediary. But the plot was betrayed by a slave who revealed it to his master. The authorities rounded up the conspirators, and the ringleaders were executed in brutal fashion — some were broken on the wheel, others hanged. The aftermath saw even tighter control over the slave population.
Lucas: It's a reminder that the Knights' power rested on a foundation of coercion. And that foundation extended beyond the island. The corso created a constant flow of captives from across the Mediterranean, fueling a slave economy that made Malta one of the wealthiest islands per capita in the region.
Luna: It's a side of the story we rarely hear. And it makes you wonder about all the other hidden histories.
Lucas: Absolutely. And that's part of why we do this show — to bring those hidden histories to light, the ones that challenge the comfortable narratives. If you appreciate that kind of deep dive, one way to keep us going is to support the show. A listener recently said that listening to these conversations feels like being invited into a time machine, and that's exactly what we aim for.
Luna: Yeah, it's like we get to travel back and see the whole picture, not just the highlights.
Lucas: Right. And listener support is what keeps this ad-free and independent. If you'd like to help, you can do it at buy me a coffee dot com slash fexingo. Just a small gesture goes a long way in helping us research and produce these episodes. No pressure, but thanks for considering.
Luna: Agreed. Now, back to the slave trade — after the 1749 conspiracy, did attitudes change at all?
Lucas: To some extent, yes. The Knights became more cautious about the size of the slave population. They also began to limit the corso to avoid provoking the Ottomans too much. But the trade continued well into the 18th century, and it only really wound down after the Knights were expelled by Napoleon in 1798.
Lucas: It's also worth noting that the Catholic Church on Malta was deeply complicit. The Inquisition itself owned slaves, and many Church institutions profited from the trade. The morality of slavery was rarely challenged from within.
Luna: What about the slaves themselves? Do we have any records of their lives?
Lucas: We do, though they're fragmentary. Some slaves converted to Christianity and were freed. Others managed to buy their freedom through work. But most lived out their lives in servitude. There are records from the bagnio of prisoners writing letters home, hoping for ransom. Some were skilled artisans who were able to work for wages, but the bulk of their earnings went to their masters.
Lucas: One striking document is a petition from a group of Turkish slaves in the 17th century, complaining about their conditions — it shows they had some limited legal recourse, but only as a collective. The Order's courts did hear slave grievances, but outcomes were rarely just.
Luna: So the Knights were both warriors and entrepreneurs, with all the moral ambiguity that implies.
Lucas: Exactly. And that's why Malta in this period is such a fascinating case study. On one hand, you have a bastion of Christendom, a bulwark against Ottoman expansion. On the other, you have a slave-based economy that resembles the plantation systems of the Atlantic world. It's a reminder that history is never black and white.
Lucas: The legacy of that slave trade is still visible today. The Maltese language contains words from Arabic, Italian, and from the slaves who were brought here. And some Maltese families can trace their ancestry back to these captives. The fortress island was built not just by knights, but by thousands of enslaved hands.
Luna: That's a powerful image to end on. Thanks, Lucas.
