Latest / Tamerlane: The Conqueror Who Tried to Rebuild the Mongol Legacy — Fexingo History / Tamerlane's Captive Steppe Strategists: The Yassa Revival
Transcript
- Lucas: So, Luna — we've talked a lot about the people Tamerlane brought to Samarkand, the artisans and scholars. But there's one thing he brought that wasn't a person — it was an idea. The Yassa, the legal code of Genghis Khan. Luna: The Yassa — that's the Mongol law code, right? Lucas: Exactly. And Tamerlane, who claimed descent from Genghis Khan's line — through the Barlas tribe — used the Yassa as a political tool. It legitimized his rule in the eyes of the steppe warriors, and it gave him a framework to govern his rapidly expanding empire. Lucas: But here's the thing — the Yassa itself is a bit of a mystery. We don't have a complete copy. What we know comes from snippets in Persian and Arab chronicles, like Ibn Arabshah and al-Maqrizi. And even they weren't always sure what was original and what was later tradition. Luna: How did Tamerlane use something so fragmentary? Lucas: He used it selectively. The Yassa was said to cover everything — military organization, taxes, family law, even how to treat animals. Tamerlane enforced the parts that served him: loyalty oaths, the chain of command, harsh penalties for desertion. And he let other parts slide, like the rule that all Mongols must follow the steppe way of life — he built palaces and cities, which the Yassa supposedly forbade. Lucas: But for his soldiers, the Yassa was sacred. It reminded them of the glory days under Genghis. By reviving it, Tamerlane cast himself as a restorer, not just a conqueror. Lucas: You know, if today's episode makes you appreciate how far we've come from the days of blood feuds and summary execution, that's the link — buy me a coffee dot com slash fexingo. Luna: It definitely makes you think about how law shapes an army's identity. Lucas: Exactly. So, the Yassa was traditionally proclaimed at a kurultai, a grand assembly. Tamerlane held his own kurultais, especially early on, to get buy-in from the tribal leaders. He'd read out the Yassa's key clauses — or his version of them — and require everyone to swear allegiance. Luna: What were those key clauses? Lucas: Things like: no stealing from a comrade, share food and water in the field, obey your commander without question, and if you retreat in battle, you and your whole unit could be executed. Another one — the Yassa said all religions were to be respected, and Tamerlane, despite his reputation for brutality, was surprisingly tolerant of Christians, Buddhists, and even Zoroastrians, at least when it suited him. Lucas: But there's a darker side. The Yassa also prescribed death for adultery, for espionage, for a third bankruptcy. And Tamerlane used that ruthlessly. After taking a city, he'd sometimes have the Yassa proclaimed, then execute anyone who violated it — which gave him legal cover for mass killings. Luna: So he was cherry-picking the parts that solidified his control. Lucas: Absolutely. And he wasn't above adding his own rules. For example, his military units, the tumens, were organized on the decimal system from the Yassa — 10, 100, 1000, 10,000. But Tamerlane also created a special corps of bodyguards and a postal relay system that went beyond what Genghis had. Lucas: One interesting detail: the Yassa forbade the enslavement of Mongols. Tamerlane upheld that — but he enslaved everyone else, including Turkic tribes that weren't considered 'true' Mongols. So he used the Yassa to create a hierarchy of peoples within his empire. Luna: How did the regular people — the farmers, the merchants — experience the Yassa? Lucas: That's the question. The Yassa was really designed for a nomadic, military society. In a settled city like Samarkand, it coexisted with Islamic law and local custom. Tamerlane's officials — the yarghuchi, or judges — would apply the Yassa mainly to military and criminal cases, while leaving civil matters to qadis. But there's evidence that the Yassa's harsh penalties, like amputation for theft, were used in the cities too, especially against rebels. Lucas: The Persian historian Sharaf al-Din Ali Yazdi, who wrote the Zafarnama, presents Tamerlane as a strict enforcer of the Yassa. But he's writing to glorify him, so we have to be careful. Luna: So the Yassa was as much propaganda as it was law. Lucas: Exactly. By invoking the Yassa, Tamerlane sent a message: I am the true heir of Genghis Khan. And that mattered because many of his rivals, like the Chagatai khans, claimed the same legacy. The Yassa gave him a moral and legal edge. Lucas: There's also a practical side. The Yassa standardized punishments across a huge empire. A soldier from Persia knew he'd face the same penalty for desertion as a soldier from Khorasan. That consistency helped hold the army together. Luna: What happened to the Yassa after Tamerlane died? Lucas: It faded. His son Shah Rukh and grandson Ulugh Beg were more Persianized — they relied on Islamic law and royal decrees. By the 15th century, the Yassa was mostly a memory, though some tribes in the steppes kept elements of it for centuries. But Tamerlane's revival of it was a key part of his brand. Luna: It's fascinating how an unwritten code — or barely written — could hold such power. Lucas: And that's the paradox. The Yassa was never fully written down in one place, but it was memorized by generations of Mongol leaders. Tamerlane's court had scribes who compiled collections of Yassa rulings, but those are lost. We have to piece it together from chronicles, many of them hostile. Lucas: Ibn Arabshah, who was captured by Tamerlane but later wrote a highly critical biography, says the Yassa was 'a mixture of justice and tyranny' — and that Tamerlane used it to justify his worst atrocities. Luna: Did any other conqueror try something similar? Lucas: Some of the later Mughal emperors in India, who were also descended from Timur, claimed to follow the Yassa in principle. But by then it was more a symbol than a functioning legal system. The last real echo was among the Kazakhs and other steppe peoples into the 19th century. Lucas: So when we think of Tamerlane's legacy, we usually think of the pyramids of skulls, the great buildings of Samarkand, the astronomy of Ulugh Beg. But one of his most important tools was something invisible — a set of laws, or the idea of them, that held his empire together. Luna: It's a reminder that empires are built on more than swords. Lucas: And on more than one person. The Yassa gave Tamerlane a framework that outlasted any single battle. It's a quieter kind of conquest.
