- Lucas: So, Luna, today we're diving into a moment that didn't end the slave trade by itself, but it changed how people back in Britain saw it. I'm talking about the Zong massacre—a single, horrifying event that became a rallying cry for abolitionists. Lucas: The year is 1781. The Zong is a British slave ship, owned by a Liverpool syndicate, on its way from the coast of Africa to Jamaica. It's carrying 442 enslaved Africans—far more than the ship could comfortably hold. And then something goes wrong. Luna: What happened? A storm? Lucas: Not exactly. The captain, a man named Luke Collingwood, made a navigational error. He overshot Jamaica, and by the time he realized, the ship was low on drinking water. Now, you'd think the first priority would be to get to port. But Collingwood had another idea. Lucas: He began ordering the enslaved Africans—133 of them—to be thrown overboard, alive. Over the course of several days, they were chained and tossed into the ocean. Some managed to climb back on board, only to be thrown again. The crew even saved some of the chains to use again. Luna: That's monstrous. But why would he do that instead of rationing water? Lucas: Because of insurance. The Zong was insured under a policy that covered 'perils of the sea'—storms, shipwreck, that sort of thing. But if slaves died of natural causes, like thirst, the owners got nothing. However, if they were thrown overboard to save the ship, that was considered a jettison—and the insurers had to pay. Lucas: So Collingwood saw a business opportunity. He calculated that the insurance money for those 133 people would be worth more than their sale price in Jamaica. The slaves were literally worth more dead than alive. Luna: That's calculated murder for profit. Did anyone on the crew object? Lucas: The first mate, James Kelsall, did—at first. But Collingwood threatened him, and eventually Kelsall went along. After the Zong finally reached Jamaica, the owners filed an insurance claim. The insurers refused to pay, suspecting fraud. So the case went to court in London in 1783. Lucas: The case was Gregson v. Gilbert. Gregson was the shipowner, Gilbert the insurer. And the entire trial was about property law—whether the slaves were legally considered cargo that could be jettisoned. Not a single charge of murder was brought. Luna: So the court just accepted that you could kill people for insurance money? Lucas: Almost. The presiding judge was Lord Mansfield, the same Lord Mansfield who had earlier ruled on the Somerset case, which some interpreted as making slavery illegal in England. But here, Mansfield instructed the jury that the case was 'the same as if horses were thrown overboard.' He said the real question was whether the captain acted from necessity—not whether the act was murder. Luna: And what did the jury decide? Lucas: They ruled for the owners. But the insurers pressed for a new trial, and during the proceedings, more details came out. The ship's log, for example, showed that after the massacre, the Zong had 420 gallons of water left—plenty to reach Jamaica. The necessity claim was a lie. Lucas: The case was never retried. Instead, it was leaked to a prominent abolitionist named Granville Sharp. Sharp was a lawyer and activist who had already fought against slavery. He saw the Zong case as the perfect weapon. Luna: How did he use it? Lucas: Sharp published the story widely, and he tried to get the Admiralty to prosecute the crew for murder. The Admiralty declined—saying the case was a matter for civil courts, not criminal. But the publicity was enormous. Sharp also recruited Olaudah Equiano, the former enslaved writer who had bought his freedom, to help spread the word. Lucas: Equiano had been on slave ships himself. He wrote letters and gave talks, and the Zong became a symbol of everything wrong with the trade. People in England were horrified that their insurance laws could treat humans as cargo. Luna: So the Zong case really did change public opinion? Lucas: It was a major turning point. The abolitionist movement had been building for years, but the Zong gave them a visceral, concrete example. It showed that the slave trade wasn't just cruel in the abstract—it was a system that incentivized mass murder. Within a few years, the Society for Effecting the Abolition of the Slave Trade was formed, and petitions flooded Parliament. Lucas: The Zong case itself faded from legal history, but its impact lasted. In 1807, Britain abolished the slave trade. And the case is often cited as the moment the tide of public opinion began to turn. Luna: And it all started with an insurance claim on human lives. Lucas: Exactly. And that's the chilling part. The men who threw those people overboard didn't see them as human; they saw them as property. The legal system initially agreed. It took people like Sharp and Equiano to force the nation to see what had really happened. Lucas: And it's a reminder that so much of this history is about everyday people saying, 'This isn't right.' I think that's part of why we keep doing these episodes. Luna: Speaking of keeping things going—how do we actually make this show? Lucas: You know, it's a good question. We don't run ads on Fexingo History—no sponsors, no commercials. That means it's entirely listener-supported. A small group of people chip in monthly through buy me a coffee dot com slash fexingo, and that covers the research, the hosting, everything. Luna: Yeah, it's honestly the only reason we can keep digging into these stories. And we're grateful to everyone who makes that possible. Lucas: Absolutely. So back to the Zong—one thing I want to underline is that the 133 people thrown overboard were named. We don't know their names, but they were individuals. And the case, for all its legal coldness, helped restore some humanity to the conversation. Lucas: Thanks for listening. And if you want to help us keep telling these stories, you know where to find us.
