Latest / Tamerlane: The Conqueror Who Tried to Rebuild the Mongol Legacy — Fexingo History / The Siege of Ankara: Tamerlane vs Bayezid the Thunderbolt
Transcript
- Lucas: You know, we've talked a lot about Tamerlane's campaigns — his wars in India, his sieges in Syria, his clashes with the Golden Horde. But today I want to focus on what might be his most famous battle, the one that really cemented his reputation in the West: the Battle of Ankara against the Ottoman sultan Bayezid I. Luna: The Thunderbolt, right? That's what Yıldırım means. Lucas: Exactly. Bayezid had earned that nickname for his speed on the battlefield. By 1402, he had expanded Ottoman control across Anatolia and into the Balkans, even defeating a Crusader army at Nicopolis in 1396. He was the rising power in the region, and he'd been encroaching on Timur's borders by annexing Turkmen beyliks that were under Timur's protection. Luna: So Timur had been watching him for a while. Lucas: Absolutely. By early 1402, Timur had already crushed the Mamluk sultanate and was marching through Anatolia. He sent letters to Bayezid, demanding he return the beyliks and submit. Bayezid's response was famously insulting — he called Timur a dog and said he'd meet him in battle. Timur later said that the letter 'filled his heart with fire.' Luna: I remember reading about that exchange. Bayezid really didn't take him seriously. Lucas: He underestimated Timur, and that was a fatal mistake. Timur's army was massive — perhaps 140,000 men — and included war elephants, though they weren't decisive here. Bayezid fielded around 85,000, including his elite Janissary infantry and the Sipahi cavalry. But here's the thing: many of Bayezid's troops were from those very beyliks Timur was claiming to protect. And Timur had been in contact with them. Luna: He turned them before the battle even started. Lucas: Exactly. The battle took place on July 28, 1402, near the city of Ankara. Timur used a classic strategy: he positioned his army to block the Ottomans from reaching a nearby river, and then he launched attacks designed to provoke Bayezid into committing his reserves. Meanwhile, he had agents within Bayezid's camp spreading discontent. As the battle wore on, entire contingents from the Turkmen beyliks switched sides. Even Bayezid's Serbian allies under Stefan Lazarević fought bravely but couldn't turn the tide. Luna: And Bayezid himself was captured, right? But there's a story about a cage... Lucas: Ah, the cage — one of the most famous legends about Timur. According to later accounts, especially from European sources, Timur supposedly kept Bayezid in an iron cage and paraded him around as a trophy. The story goes that Bayezid died in captivity from a broken heart, or maybe he smashed his head against the bars. But contemporary sources like the Zafarnama and Ibn Arabshah don't mention a cage. Ibn Arabshah, who was hostile to Timur, says Bayezid was treated well initially but died of illness — possibly a stroke or an infection — about eight months later. The cage story appears in later chronicles, likely as propaganda to portray Timur as a barbarian. Luna: So it's probably a myth, but it stuck. Lucas: It stuck hard. You see it in paintings and plays all through the Renaissance. Christopher Marlowe wrote a play called Tamburlaine the Great that features the cage. But the reality is less dramatic and more interesting. Bayezid's capture and death triggered a civil war among his sons — the Ottoman Interregnum we covered in another episode. That period of chaos gave the Ottomans a decade of fragmentation, which Timur exploited to redraw the map of Anatolia. Luna: He restored the beyliks, didn't he? Handed the territory back to their native rulers. Lucas: He did. Timur saw himself as a restorer of the Mongol order, which in his view meant a federation of vassal states under his supreme authority. He didn't want to rule Anatolia directly — he just wanted to humble the Ottomans and ensure no rival empire emerged. So after the battle, he reinstated the Turkmen beyliks and even gave some territory to the Byzantine Empire, which had sent him a diplomatic mission. It was a strategic rebalancing. Luna: And the Byzantine Empire got a few more decades of life out of it. Lucas: Exactly. Constantinople was saved, temporarily, from Ottoman siege. The Battle of Ankara is often seen as a pivotal moment: if Bayezid had won, he might have taken Constantinople decades earlier. Instead, the Ottomans had to pause and regroup. Timur, meanwhile, turned his attention eastward and began planning his invasion of Ming China — which he died before completing. So in a way, the battle shaped not just Anatolia but the entire Eurasian balance of power. Luna: Looking at the battle itself, how did Timur's tactics differ from what the Ottomans were used to? Lucas: Great question. The Ottoman army was based on a mix of feudal cavalry and the Janissary corps — disciplined infantry armed with bows and later guns. But Timur brought a steppe tradition: mobile archers on horseback, feigned retreats, and psychological warfare. He also used his engineers to dig trenches and divert water, which left the Ottoman troops exhausted and thirsty. The battle started around midday in the blazing Anatolian summer, and by late afternoon, the Ottoman center was broken. Bayezid himself was captured during the rout, along with many of his commanders. Luna: And what happened to Bayezid after his capture? The non-cage version. Lucas: According to the Zafarnama, Timur received Bayezid with respect, expressing admiration for his martial prowess. He was kept under guard but not mistreated. But within several months, Bayezid's health deteriorated — perhaps from the stress, or from an illness. He died in March 1403 in Akşehir, while Timur was still in Anatolia. Timur allowed his body to be taken to Bursa for burial, which was a gesture of honor. So the cage story is almost certainly a later invention, possibly by European chroniclers who wanted to paint Timur as a savage. Luna: It shows how history gets shaped by the stories we tell. Lucas: Absolutely. The Battle of Ankara is one of those events that has been mythologized on both sides. For the Ottomans, it was a humiliating defeat that taught them the importance of unity. For the Timurids, it was proof of their founder's invincibility. And for Europe, it was a moment of relief and fascination — a chance to see the dreaded Turk brought low by an even more fearsome conqueror. In the end, it's a story about the fragility of empires and the unpredictability of war.
