Transcript
- Lucas: Last time we talked about the astronomers Tamerlane brought to Samarkand, but there's another group of captives that had a huge impact on his military campaigns — and they came from a place you might not expect: the Ottoman Empire. Luna: Wait, Tamerlane fought the Ottomans? I thought he fought mostly in Persia and India. Lucas: He did, but in 1402 he clashed with the Ottoman Sultan Bayezid I at the Battle of Ankara. It was a massive confrontation — both sides had around 100,000 men. Tamerlane won decisively, captured Bayezid, and then his armies swept through Anatolia. Lucas: And among the spoils he brought back to Samarkand were not just gold and silk, but people — specifically, Turkish military engineers. These were the guys who knew how to build siege engines, from trebuchets to battering rams, and they were experts in undermining walls. Luna: So he basically imported the Ottoman siege corps? Lucas: Exactly. The Ottomans had a well-developed tradition of siege warfare, partly inherited from Byzantine and Persian practices. Tamerlane recognized that his own steppe army, while brilliant in open battle, needed heavy engineering to crack the fortified cities of Persia, Syria, and India. Lucas: So he settled these engineers in a dedicated district of Samarkand, not far from the main kar-khana — the state workshops. They were given materials, slaves, and a steady stream of projects. Over time, they built a siege train that was probably the most advanced in Central Asia. Luna: What kind of siege engines are we talking about? Trebuchets, like the ones the Mongols used? Lucas: Trebuchets, yes, but also mangonels, battering rams covered with metal plates, and mobile siege towers called pavises. The Zafarnama describes Tamerlane using 'stone-throwing engines' that could hurl projectiles weighing over a hundred kilograms. At the siege of Damascus in 1401, his engineers reportedly built a trebuchet that took a week to assemble. Lucas: And here's the interesting part: these Turkish engineers also brought knowledge of early gunpowder weapons. The Ottomans were already experimenting with primitive cannons and handguns by the late 1300s. Tamerlane's campaigns might have been among the first in Central Asia to use gunpowder in siege warfare. Luna: Wait, really? I thought gunpowder came to the Middle East later, like in the 1500s. Lucas: That's a common assumption, but there's evidence of gunpowder weapons in the Ottoman arsenal by the 1390s. Ibn Arabshah, a contemporary Arab historian who was captured by Tamerlane, writes about 'fire tubes' used by the Ottomans at Ankara. And after the battle, Tamerlane's engineers began producing something called 'huojian' — fire arrows — that were basically early rockets. Lucas: Now, the Chinese had been using gunpowder for centuries, but the transfer to the Islamic world was slow. Tamerlane's captive engineers might have accelerated that process, combining Ottoman know-how with Chinese ingredients and Persian metalworking. Luna: So Samarkand became a kind of melting pot for military tech. Lucas: Exactly. And this is where the story gets even more interesting. The engineers didn't just build weapons — they also trained local artisans. The Zafarnama mentions that Tamerlane ordered the creation of a permanent siege workshop, the kar-khana, where master engineers from different traditions worked together. Lucas: You had Turkish siege specialists, Persian architects, Mongol cavalry tacticians, and Chinese pyrotechnicians all in one complex. The Yassa, the Mongol legal code, was adapted to regulate these workshops. Tamerlane himself, the Sahib-i Qiran — the Lord of the Auspicious Conjunction — personally inspected the production lines. Luna: That's a lot of coordination. Did these engineers also influence the design of Samarkand's fortifications? Lucas: Absolutely. After capturing cities like Damascus and Bukhara, Tamerlane had his engineers study their walls and adapt their designs. The Bibi-Khanym mosque, which we've talked about before, was built partly with stone brought from India and carving techniques from Persian stonemasons. But the city walls themselves were reinforced based on Ottoman and Syrian models. Lucas: In fact, when the Spanish ambassador Ruy González de Clavijo visited Samarkand in 1404, he described the city's fortifications as 'very strong, with towers and double walls.' That was a direct result of Tamerlane's investment in siege engineering. Luna: I never connected Tamerlane's building projects with his military campaigns. It's like he conquered cities to learn how to build better ones. Lucas: That's a great way to put it. And the same pattern applied to his later campaigns. When he invaded India in 1398, his engineers built a bridge of boats across the Indus River in just a few days — a technique they likely learned from Ottoman or Persian engineers. Lucas: Then at the siege of Delhi, they used a combination of trebuchets and sappers to breach the walls. The Zafarnama says the bombardment lasted for hours, and the defenders were terrified by the 'thunder of the stones.' Luna: It's amazing how much detail survives in those chronicles. Lucas: Speaking of which, we're able to bring you these stories because of the time we put into researching primary sources. And if you've been getting value from these episodes, a couple of dollars a month — buy me a coffee dot com slash fexingo — genuinely helps keep the podcast ad-free and allows us to keep digging into these overlooked histories. Luna: Yeah, it really does. Every little bit helps us keep the show going. Lucas: So back to the engineers: after Tamerlane's death in 1405, his successors, especially his grandson Ulugh Beg, continued to support the kar-khana. But the siege workshop gradually declined as the empire fractured. Still, the legacy lived on. Lucas: Decades later, when Babur founded the Mughal Empire in India, he brought with him the Timurid tradition of siege engineering, including the use of Ottoman-style cannons. That's a direct line from Tamerlane's captive Turkish engineers to the artillery that helped Babur conquer northern India. Luna: So Tamerlane's hostage-taking actually ended up shaping the military technology of later empires? Lucas: Exactly. It's one of those unintended consequences of his empire-building. He captured engineers to serve his own immediate needs, but the knowledge transfer that happened in Samarkand had ripple effects for centuries. Lucas: And it's not just gunpowder. The Ottoman siege techniques that were refined in Samarkand later influenced the Safavids and even the Mamluks. The Zafarnama, written by Sharaf al-Din Ali Yazdi, describes these engineers in detail, but it's a part of Tamerlane's story that often gets overlooked. Luna: I feel like every episode we do, there's another layer to this guy. It's hard to believe one man had such a wide reach. Lucas: That's what makes him so fascinating — and so terrifying. He wasn't just a conqueror; he was a systematizer. He took expertise from everywhere and concentrated it in his capital. And through that, he created a brief but brilliant synthesis of Central Asian, Persian, Ottoman, and Indian military traditions.
