Transcript
- Lucas: So we've spent a lot of time on the Atlantic slave trade, but there's another massive slave trade that ran in the Indian Ocean, centered on Zanzibar. And it's intimately connected to one crop: cloves. Luna: Cloves? Like the spice? Lucas: Exactly. In the early 19th century, the Omani Sultan, Said bin Sultan, moved his capital from Muscat in Oman to Zanzibar in the 1840s. He saw that Zanzibar's soil was perfect for cloves. He forced plantation owners to grow them, and soon Zanzibar became the world's leading clove producer. But the plantations required massive labor, and that labor came from enslaved Africans. Lucas: The slave trade in East Africa had existed for centuries, but it exploded under Omani rule. By the mid-1800s, Zanzibar was the largest slave market in East Africa. The Mkunazini slave market, right in Stone Town, was where thousands of people were sold every year. Luna: How many people were being trafficked? Lucas: Estimates vary, but between 1830 and 1870, at least 600,000 slaves were shipped from East Africa to Zanzibar and other Indian Ocean destinations. Many were taken from the interior by traders like Tippu Tip, a Swahili-Arab slave and ivory trader who operated deep in the Congo Basin. Lucas: Tippu Tip was an incredibly powerful figure. He used firearms to raid villages, capturing people from the Nyamwezi, Yao, and Makua groups. He marched them in coffles to the coast at Bagamoyo or Kilwa, then shipped them to Zanzibar. Luna: And then they were forced to work on clove plantations. Lucas: Right. On Zanzibar and Pemba islands. The conditions were brutal. Slaves worked from dawn to dusk, often beaten if they didn't meet quotas. Many died from exhaustion or disease. The mortality rate on the plantations was high, and the trade kept feeding new slaves in. Luna: So the clove industry was built on a constant supply of enslaved people. Lucas: Exactly. And the British, who had abolished their own slave trade in 1807, were complicit for decades. They signed anti-slave trade treaties with Zanzibar's sultans, but enforcement was weak. The British navy patrolled the coast, but they only had so many ships. And the Omani rulers often turned a blind eye. Lucas: It wasn't until the Heligoland-Zanzibar Treaty of 1890, where Britain traded Heligoland to Germany in exchange for Zanzibar, that the British took direct control. In 1897, Sultan Hamoud bin Mohammed, under British pressure, finally abolished slavery in Zanzibar. But even then, many former slaves remained on plantations as 'squatters' with little freedom. Luna: So the end of slavery in Zanzibar was really a slow process. Lucas: Very slow. And the legacy is still visible today. Stone Town's architecture, the winding alleys, the carved doors — they were built with wealth from cloves and slaves. It's a dark history that's often overlooked compared to the Atlantic trade. Luna: It's amazing how a single spice can drive such human suffering. Lucas: Yeah, and it's a reminder that the slave trade wasn't just an Atlantic phenomenon. The Indian Ocean trade connected Africa, the Middle East, and Asia in a network of exploitation that lasted well into the 19th century. It's a story that deserves more attention.
