- Lucas: So, we've talked a lot about the slave trade itself — the ships, the plantations, the revolts. But I want to step back and look at how Britain, which was the biggest slave-trading nation by the 18th century, actually ended its involvement. And it wasn't a foregone conclusion. Luna: You mean the abolition movement? I know Wilberforce is famous, but wasn't there a lot more to it? Lucas: Absolutely. Wilberforce was the parliamentary face, but the movement was a grassroots phenomenon. It started with Quakers in the 1750s and 60s — they were among the first to condemn slavery on religious grounds. Then you had Granville Sharp, a civil servant who took up the cause after a enslaved man named Jonathan Strong was beaten by his owner in London. Sharp helped get a ruling that a slave couldn't be forcibly removed from Britain. Luna: So that was the Somerset case? I remember that from an earlier episode. Lucas: Exactly — Somerset v Stewart in 1772. Lord Mansfield ruled that slavery wasn't supported by common law in England. It didn't end slavery, but it made it clear that enslaved people couldn't be forced out of the country. That became a rallying point. Then in the 1780s, a group of abolitionists formed the Society for Effecting the Abolition of the Slave Trade. Key figures were Granville Sharp, Thomas Clarkson, and a few Quakers like William Dillwyn. They focused on the trade itself, not slavery outright, thinking that was more achievable. Luna: Why the trade rather than slavery? Lucas: They thought abolition of the trade would choke the system. If you stop new supplies, plantations wither. Plus, it was easier to get public outrage over the Middle Passage than over the institution as a whole. Thomas Clarkson spent years traveling to ports like Bristol and Liverpool, gathering evidence from sailors and ship logs — the horrors of the slave ships. He even collected samples of shackles and branding irons to show Parliament. He published a book in 1786 called An Essay on the Slavery and Commerce of the Human Species. Luna: Wow, that's really hands-on research. Did that sway public opinion? Lucas: It did, but slowly. The big turning point was the Zong massacre trial in 1783. You'll remember from episode 4 — the ship's captain threw 133 enslaved people overboard to claim insurance. When the case came to court, Granville Sharp pushed for murder charges. The insurer won, but the details were horrific. It galvanized the public. By 1788, the abolitionists organized a massive petition campaign — over 100,000 signatures across Britain. Parliament held its first debate on the slave trade that year. Luna: A hundred thousand signatures in the 18th century — that's incredible. How did they get that many? Lucas: Local committees. They went church to church, town to town. They printed pamphlets, gave lectures, used networks of Quakers and Methodists. Thomas Clarkson rode on horseback across England, speaking at meetings and gathering witness testimony. There was also a huge push to boycott slave-grown sugar. Thousands of people stopped using sugar — which was a big deal in tea-drinking Britain. The boycott was led by women, who were otherwise excluded from politics. Luna: So women were involved even though they couldn't vote? Lucas: Exactly. Women organized local abolition societies, boycotts, and fundraisers. Hannah More wrote poems and plays against the trade. But they couldn't sit in Parliament, so they worked through moral suasion. Meanwhile, William Wilberforce took up the cause in the House of Commons. He introduced a bill to abolish the slave trade in 1789, but it failed. He tried again and again — year after year — often losing by narrow margins. It took 18 years of political maneuvering, wars, and shifting public opinion. Luna: What finally made it pass in 1807? Lucas: A combination of factors. The Haitian Revolution made people associate slavery with rebellion and instability. The Napoleonic Wars made the government want to undercut France's colonies. And the abolitionists kept up the pressure — over 300 petitions were submitted in 1806 alone, with more than half a million signatures. Wilberforce and his allies tied the abolition bill to a Foreign Slave Trade Bill that banned British involvement in supplying slaves to foreign colonies. That passed in 1806, and then in 1807, the Act for the Abolition of the Slave Trade passed overwhelmingly. Luna: So it was a long, hard fight. But it only ended the trade, not slavery itself. Lucas: Right. That took another 26 years. The 1833 Slavery Abolition Act finally freed all slaves in the British Empire, with a system of apprenticeship and compensation for slave owners. But the 1807 act was the first crack. It banned British ships from carrying slaves, and the Royal Navy then enforced it with the West Africa Squadron. They freed thousands of captives and resettled them in Sierra Leone. The abolition movement became a model for later human rights campaigns — it showed that a dedicated minority could change the mind of a nation. Luna: It's amazing to think how much changed in one generation. From the Zong massacre to the end of the trade. Lucas: It really is. And it wasn't inevitable — it took people like Clarkson, Sharp, Equiano, and thousands of anonymous petitioners. Their moral outrage, combined with political savvy, shifted the course of history.
