Latest / The Atlantic Slave Trade: Empire Built on Human Suffering — Fexingo History / The 1788 Dolben Act: Britain's First Slave Ship Regulation
Transcript
- Lucas: So we've talked a lot about the horrors of the Middle Passage — the Zong massacre, the Brookes diagram, the testimonies that drove the abolition movement. But there's a parliamentary story that often gets overlooked: the very first law ever passed to regulate conditions on British slave ships. It came in 1788, and it was called the Dolben Act. Luna: Wait — a law to regulate the slave trade, before abolition was even on the table? Lucas: Exactly. It didn't end the trade — far from it. But it was the first time Parliament acknowledged that the treatment of enslaved Africans during the voyage was a matter of public concern. And it happened largely because of a backbench MP who'd never been particularly vocal on the issue before: Sir William Dolben. Lucas: Dolben was a member for Oxford University, which sounds like an odd base for slave trade reform. But he was genuinely horrified by what he learned from Thomas Clarkson's research — especially the testimony from James Field Stanfield, the sailor we talked about in episode 142, who'd actually served on a slave ship and wrote a searing account of the conditions. Luna: So what did the Dolben Act actually do? Lucas: It set a maximum number of enslaved people that could be carried per ship, based on the vessel's tonnage. Before the act, ships like the Brookes — which Clarkson had publicized with that famous diagram showing 454 people crammed into every available space — could pack in as many as they wanted. The Dolben Act limited that. For a ship of a certain size, you could only carry a certain number. It also required that every ship carry a surgeon to document deaths and illnesses. Lucas: Now, it wasn't exactly humane by modern standards. But it was a start. The act reduced the average number of enslaved people per voyage by about a third, and mortality rates did drop in the years that followed. Not because slave traders suddenly cared about human life, but because overcrowding literally killed their cargo, and this law forced them to spread the suffering out a bit. Luna: And the Liverpool merchants fought it tooth and nail, I'm guessing? Lucas: Oh, absolutely. Liverpool was the epicenter of the British slave trade, and its representatives in Parliament argued that the act would destroy the trade entirely. They claimed it was an infringement on private property rights — that a ship owner had the right to use every inch of his vessel as he saw fit. One MP even said the bill was 'a libel on the character of the British merchant.' They tried to water it down with amendments, but Dolben held firm. Lucas: And he had powerful allies. William Wilberforce, who was just beginning his abolition campaign, spoke in favor of the bill. So did Prime Minister William Pitt the Younger. The act passed the Commons by a comfortable margin, then cleared the Lords, and received royal assent in July 1788. Luna: It's interesting — the first real legislative win for the abolition movement wasn't a ban, but a regulation. It's like they had to prove they could limit the trade before they could end it. Lucas: That's a really sharp observation. And you're right — the Dolben Act was a test case. It showed that Parliament could intervene in the slave trade at all, which was a huge psychological shift. Before 1788, the trade was seen as a private commercial matter, almost sacred. After the Dolben Act, it became something the state could regulate. Lucas: But there were obvious loopholes. The act only applied to British ships, so some traders simply reflagged their vessels or transferred them to foreign ownership. And enforcement was spotty — the government appointed a few surveyors, like a man named John Reeves, who inspected ships at Liverpool and Bristol, but he couldn't be everywhere. Still, the act was renewed every year until 1799, when it was made permanent. Luna: So the Dolben Act is really the first crack in the wall. It's not abolition, but it's the beginning of the end. Lucas: Exactly. If you've been stepping into history with us episode by episode, you've seen how the movement built momentum — from Granville Sharp's legal victories to Clarkson's research to the Zong trial. The Dolben Act is the moment that momentum hits Parliament for the first time. And honestly, if today's episode was worth a coffee to you, that's the link — buymeacoffee dot com slash fexingo. It's a small gesture that keeps these conversations going, ad-free. Luna: Yeah, it really does make a difference. And it's nice to know that listener support is what keeps this show independent. Lucas: Alright — back to the Dolben Act. One of the most fascinating details is how the act actually set the numbers. Dolben and Clarkson used data from the Privy Council's investigation into the slave trade, which had collected information on ship capacities and mortality rates. They established a ratio: for ships under 200 tons, you could carry 1.5 enslaved people per ton; for larger ships, the ratio was slightly lower. It was crude, but it gave them a legal formula to work with. Luna: So the act actually had a mathematical basis. It wasn't just a random limit. Lucas: Right. And that math mattered. Before the act, the average British slave ship carried about 2.5 enslaved people per ton. After, it dropped to around 1.7. That's a huge reduction in density. Of course, shippers tried to cheat — they'd underreport the tonnage of their ships, or they'd squeeze in extra people and bribe the inspectors. But overall, the act had a measurable effect. Lucas: There's also the question of who actually enforced it. The government appointed John Reeves as the first 'Inspector of the Slave Trade' in 1789. Reeves was a naval officer with a reputation for integrity. He traveled to Liverpool and Bristol, examined ships, and prosecuted violators. But his powers were limited — he could only inspect ships before they sailed, not during the voyage. And the fines for breaking the act were relatively small, so some traders simply factored them into their costs. Luna: So it was a step forward, but not a revolution. Still, it set a precedent that the trade could be regulated at all. Lucas: Exactly. And that precedent was crucial. When the abolitionists finally pushed for the end of the British slave trade in 1807, they could point to the Dolben Act as proof that Parliament had authority over the trade, and that regulation could work. It also gave them a model for what a complete ban might look like — a system of inspections, penalties, and oversight. Lucas: So the Dolben Act is one of those quiet, incremental reforms that doesn't get the same attention as the big dramatic moments — the Somerset case, the Zong trial, the 1807 abolition. But without it, the abolition movement might never have gotten its foot in the door. Luna: It's the kind of story that reminds you how change happens in steps. Not always with a bang, but with a bill.
