Transcript
- Lucas: We've talked a lot about Tamerlane as a destroyer — the towers of skulls, the cities razed. But there's another side to his conquests that doesn't get as much attention: the knowledge he stole. Luna: Stole? You mean like looted books? Lucas: Books, yes, but also people. When he took a city, he'd order his soldiers to round up the scholars — astronomers, mathematicians, physicians, calligraphers — and march them back to Samarkand. He wanted the intellectual elite of the Islamic world working for him. Luna: So he basically kidnapped entire universities. Lucas: Exactly. And it wasn't random. We know from the Zafarnama and from Ibn Arabshah that Tamerlane had a specific policy: skilled craftsmen and scholars were to be separated from the general population and sent east. In Damascus, for example, after the siege of 1401, he had the Umayyad Mosque's library ransacked, but he also took the astronomer Jamal al-Din and his colleagues. They ended up in Samarkand, where they helped build the city's first observatory. Luna: Jamal al-Din — was he the one who later worked with Ulugh Beg? Lucas: Not directly — Ulugh Beg was Tamerlane's grandson, and his famous observatory came decades later. But the foundation was laid by Tamerlane. He brought in Persian and Arab astronomers, set up a madrasa in Samarkand, and commissioned translations of Greek and Persian scientific texts. The Zafarnama boasts that Samarkand became a 'second Cairo' for learning. Luna: But wasn't he illiterate? I remember reading that he couldn't read or write. Lucas: That's a contested point — some sources say he was illiterate, others that he could read but not write. Either way, he clearly valued knowledge. He loved hearing history and astronomy read aloud, and he surrounded himself with advisors who were scholars. But there's also a darker pragmatism: by moving the best minds to his capital, he was depriving rival cities of their intellectual capital. Luna: So it was a form of cultural warfare. Lucas: Exactly. And it worked. After Tamerlane's death, Samarkand became the center of the Timurid Renaissance. Ulugh Beg's observatory, the beautiful madrasas, the development of Timurid miniature painting — all of that traces back to Tamerlane's forced relocation of scholars. But it came at a huge cost to the cities he emptied. Luna: What about the scholars themselves? Did they have any choice? Lucas: Very little. Ibn Arabshah, who was captured as a child and taken to Samarkand, wrote bitterly about his experience. He says the scholars were treated well materially — given houses, stipends, access to libraries — but they were prisoners. Some adapted and thrived, others tried to escape and were executed. It was a gilded cage. Luna: Hmm. So Tamerlane saw knowledge as a resource, like gold or slaves. Lucas: Exactly. And that's the paradox: he could destroy a city like Isfahan, killing tens of thousands, and then personally oversee the construction of a madrasa in Samarkand. His chroniclers struggled to explain this. Some portray it as a sign of his greatness — he could be both a sword of God and a patron of learning. Others, like Ibn Arabshah, saw it as pure hypocrisy. Luna: Did any of those scholars end up influencing Ulugh Beg directly? Lucas: Yes, some of the astronomers Tamerlane brought in — like Jamal al-Din's students — lived long enough to teach Ulugh Beg. The observatory built around 1420 used instruments that were essentially upgrades of what the Damascene astronomers had developed. So in a way, Tamerlane's kidnapping of scientists planted the seeds for one of the greatest scientific achievements of the 15th century: Ulugh Beg's star catalogue, which was the most accurate in the world for over 200 years. Luna: That's an incredible legacy. But hard to celebrate when you think about how it started. Lucas: Right. And that's the tension we're left with. Tamerlane's patronage of learning was real — he funded libraries, built madrasas, paid translators. But it was also a form of looting. He took the best minds of his conquered cities and brought them to Samarkand not out of pure love of knowledge, but because he wanted to consolidate power. The intellectual flowering of the Timurid period is built on the ruins of Damascus, Baghdad, and Herat. Luna: It makes you wonder: what if those scholars had stayed in their home cities? Would the Renaissance have happened in Syria or Iraq instead? Lucas: That's a fascinating counterfactual. Some historians argue that the Timurid Renaissance was a direct result of concentrating so many scholars in one place — that the cross-pollination of ideas from different regions created something new. Others say it was just a transfer, not a creation. We'll probably never know for sure. Luna: Before we move on, I want to say something. If you're finding these deep dives useful — if this kind of nuance is why you listen — you should know that the show stays ad-free because listeners chip in. You can find us at buy me a coffee dot com slash fexingo. It's a small way to keep this going. Lucas: Yeah, that's exactly right. We pour a lot into these episodes, and knowing they're valuable to you makes it worth it. Now, back to the scholars in Samarkand — one of the most interesting figures was Ghiyath al-Din Jamshid al-Kashi, a mathematician and astronomer from Kashan. He worked at Ulugh Beg's observatory, and his calculations of pi were astonishingly precise. Luna: Was he one of the kidnapped scholars too? Lucas: Actually, no — he came voluntarily, which is rare. Ulugh Beg invited him, and he was so attracted by the resources in Samarkand that he moved there willingly. That shows the pull of the intellectual center Tamerlane had created. But most of the early generation were forced migrants. Luna: It's wild to think that Tamerlane's brutal conquests inadvertently created a scientific golden age. Lucas: It is. And it's a reminder that history isn't neat. Good things can come from terrible origins. The same hands that stacked skulls also laid the foundation for one of the most advanced observatories in the medieval world. That's the kind of contradiction that makes Tamerlane so endlessly fascinating.
