Transcript
- Lucas: So, we've talked a lot about slave revolts and mutinies on the high seas, but I want to step back and look at the economic engine that kept the transatlantic slave trade churning well into the 19th century—specifically, Cuba's sugar boom in the 1830s. Luna: I know Cuba was a big sugar producer, but why the 1830s specifically? Lucas: Great question. By the 1820s, most Spanish American colonies had won independence, but Cuba stayed loyal to Spain. And with the Haitian Revolution wiping out Saint-Domingue as the world's top sugar producer, Cuba saw an opening. The Spanish crown actively encouraged plantation expansion, and the result was an explosion of sugar production—and, with it, a massive surge in slave imports. Lucas: If today's conversation gives you a clearer picture of how this system really worked, the reason we can keep doing these deep dives without ads is listener support. You can help at buymeacoffee.com/fexingo—just a small thing that lets us keep the focus on the history. Luna: Yeah, it's a good way to make sure the show stays independent and we can tackle these specific stories. Lucas: Exactly. So, the key figure here is Francisco de Arango y Parreño. He was a Cuban creole economist and planter who essentially wrote the blueprint for the island's sugar boom. In the 1790s, he published a treatise arguing that Cuba needed unlimited slave imports to compete with other colonies, and he lobbied the Spanish crown to relax trade restrictions. Luna: So he's basically the architect of Cuba's plantation system? Lucas: Pretty much. His ideas led to the Royal Cédula of 1789, which liberalized the slave trade to Cuba, and by the 1830s, the island was importing tens of thousands of Africans each year—legally and illegally. Britain had banned the slave trade in 1807 and pressured Spain to sign a treaty in 1817 outlawing it, but Cuba's planters found ways around it. Lucas: They used contraband ships flying false flags, bribed officials, and landed captives on remote beaches. The British Navy's West Africa Squadron tried to intercept them, but the sheer volume made it impossible. Between 1821 and 1830, an estimated 200,000 Africans were brought to Cuba illegally. Luna: That's staggering. So the 1817 treaty was basically ignored? Lucas: For the most part, yes. The Spanish colonial authorities in Cuba turned a blind eye because the sugar economy depended on it. And the technology was changing, too. The old trapiche—animal-powered mills—were replaced by steam-powered ingenios. A single steam mill could process as much cane in a day as dozens of animal mills, but it also required a much larger workforce to feed the machinery. Lucas: This is where the 'grinding season'—la zafra—became a brutal endurance test. During harvest, enslaved workers labored 18 to 20 hours a day, often in shifts, cutting cane and feeding the mills. The accident rate was horrific: people lost hands and arms to the rollers. And because the mills ran continuously, there was no downtime. Luna: Was there any resistance specific to these sugar plantations? Lucas: Absolutely. There were small-scale revolts and individual acts of sabotage—burning cane fields, breaking machinery, poisoning overseers. But the most famous rebellion tied to this era is the 1833 mutiny on the Cuban schooner Amistad, which we covered in an earlier episode. That ship was carrying 53 African captives from Havana to a sugar plantation when they revolted. Lucas: But the Amistad was just one ship. The scale of the illegal trade meant that for every successful revolt, there were hundreds of ships that made it through. And the conditions on sugar plantations were so deadly that the enslaved population couldn't reproduce naturally—they had to keep importing people just to maintain the workforce. Luna: So it's a system that literally consumes people. Lucas: Exactly. The mortality rate on Cuban sugar plantations was brutal. A typical enslaved person might last 7 to 10 years before dying from overwork, disease, or malnutrition. And the demand was so high that the price of a prime field hand in Havana rose from around 300 pesos in 1800 to over 500 by the 1830s. Lucas: One interesting detail is the role of the 'Jamaica train'—not the railroad, but a system of shallow iron boiling pans that sped up sugar crystallization. It was invented in Jamaica in the late 18th century and adopted widely in Cuba. It made production more efficient, but also more dangerous, because workers had to skim boiling liquid sugar manually. Luna: Wait—so the name 'Jamaica train' is for a boiling system, not a train? Lucas: Right. It's a series of copper or iron kettles arranged in a row, heated by a single furnace. The cane juice flows from one to the next, getting thicker and hotter. Workers had to stir and transfer the liquid with long ladles, and if they slipped, they'd fall into the boiling syrup. Burns were common and often fatal. Lucas: So the sugar boom in Cuba created what historians call a 'sugarocracy'—a small elite of planters who controlled the island's economy and politics. Men like Arango and the Count of Villanueva amassed huge fortunes, built lavish townhouses in Havana, and dominated the colonial government. Luna: Were there any voices in Cuba arguing against the slave trade? Lucas: A few, but they were marginalized. Some Cuban intellectuals, like José Antonio Saco, criticized the slave trade on moral and demographic grounds, arguing that it would lead to a African majority and threaten Spanish control. But the planters had too much power, and the Spanish crown relied on Cuba's revenue to prop up its empire. Lucas: And there's a tragic irony: the 1837 cholera epidemic hit Cuba hard, killing perhaps 100,000 people, including many enslaved laborers. The planters responded by importing even more Africans to replace the dead, which just prolonged the trade. By 1840, enslaved people made up over 40% of Cuba's population—one of the highest percentages in the Americas. Luna: So the abolition of the slave trade in the British Empire didn't really slow things down in Cuba—it just made it illegal and more brutal. Lucas: Exactly. And that's the key takeaway: the demand for sugar in Europe and the United States drove a massive, illegal slave trade to Cuba that continued well into the 1860s. The last slave ship to reach Cuba, the Pedro, arrived in 1866, decades after Britain had outlawed the trade. So the sugar boom of the 1830s was a pivotal moment—it entrenched slavery in Cuba for another generation. Lucas: It's a reminder that economic incentives can overpower legal and moral reforms. The same forces that drove the early Atlantic slave trade—profit, demand, and political power—kept it alive long after it was supposed to be dead.
