Transcript
- Lucas: In 1393, Tamerlane was at the height of his power. He'd crushed the Kipchak Khan Tokhtamysh, conquered Persia, and was eyeing the remnants of the Mongol Ilkhanate. But then he did something that surprised even his own commanders: he launched a campaign not against infidels, but against fellow Muslims, and he justified it as a holy war against heretics. Luna: Wait, he declared war on other Muslims? I thought the whole point of his conquests was rebuilding the Mongol Empire, not religious purification. Lucas: That's the tension at the heart of his later reign. Tamerlane styled himself as the 'Sword of Islam' and the 'Shadow of God on Earth'. But he was perfectly happy killing Muslims by the tens of thousands when it suited him. The difference was, he needed a theological excuse, and he found it in the concept of takfir — declaring someone an apostate. If he could label a rival ruler a heretic, then war against them was not only legal but a religious duty. Luna: So who did he target first? Lucas: One of his first targets was the Sarbadars of Sabzevar, in northeastern Iran. The Sarbadars were a Shia-leaning movement — they were known for their egalitarian, almost revolutionary politics. They'd rebelled against Mongol rule decades earlier and established a republic of sorts. Tamerlane saw them as a perfect target: they were not orthodox Sunnis, they were politically independent, and their territory lay right on his route into Persia. In 1381, he besieged Sabzevar and massacred the defenders. The Zafarnama, his official biography, describes how he had the Sarbadar leaders flayed alive and their skins stuffed with straw. That's the thing about these religious campaigns: the violence was as extreme as anything he did to non-Muslims. Luna: Flayed alive and stuffed? That's... a level of brutality that's hard to wrap my head around. Lucas: It was meant to be a message. But the Sarbadars were just the beginning. In 1393, Tamerlane turned his attention to the Muzaffarids of Shiraz and Isfahan. The Muzaffarids were Sunni Muslims, but they had resisted Tamerlane's overlordship. More importantly, they had sheltered poets and scholars who had mocked Tamerlane — most famously Hafiz of Shiraz, whom we've talked about before. But the Muzaffarid ruler, Shah Mansur, was no heretic; he was a devout Muslim. So Tamerlane needed a pretext. He accused Shah Mansur of being a rebel against legitimate authority — which, in Tamerlane's mind, was himself as the restorer of the Mongol Yassa and Islamic law combined. The battle of Patila in 1393 was decisive: Shah Mansur was killed, and Tamerlane entered Shiraz in triumph. He then executed many of the Muzaffarid nobles and claimed he was purifying the city of corruption. Luna: So he was using religion as a cover for political consolidation. Lucas: Absolutely. But here's where it gets really interesting. In 1393, Tamerlane also marched on Baghdad, then under the Jalayirid sultan Ahmad Jalayir. The Jalayirids were a Mongol successor state, culturally Persianized, and they were Sunni. But Ahmad had allied with Tamerlane's enemies, the Mamluks and the Ottoman sultan Bayezid. So Tamerlane needed to delegitimize him. He accused Ahmad of being a bad Muslim — of neglecting prayer, of surrounding himself with corrupt officials, of failing to enforce sharia. Ibn Arabshah, the Syrian historian who hated Tamerlane, records that Tamerlane's scholars issued a fatwa authorizing war against the Jalayirids because they had "deviated from the path of Islam". The result was the sack of Baghdad in 1393, though Ahmad escaped. Tamerlane's forces massacred thousands and destroyed many of the city's mosques and libraries. Luna: Destroying mosques seems counterproductive if you're claiming to fight for Islam. Lucas: Exactly. And that's the contradiction. The Zafarnama, written by Sharaf al-Din Ali Yazdi, tries to spin it as a necessary cleansing — these mosques had become dens of heresy, they said. But Ibn Arabshah, writing from a Mamluk perspective, calls Tamerlane a hypocrite and a tyrant. He points out that Tamerlane's own court was filled with astrologers, that he consulted soothsayers, and that he was more attached to the Yassa, the Mongol customary law, than to the sharia. In fact, Tamerlane never fully converted to Islam in the way the ulama would have wanted. He kept many Mongol customs, like the law of the steppe, and he was deeply superstitious. So when he claimed to be fighting for Islam, many contemporary scholars saw it as a cynical ploy. Luna: But did any religious authorities actually buy it? Lucas: Some did. Tamerlane was very careful to cultivate a network of religious scholars — the ulama — who would support his actions. He built madrasas, endowed mosques, and patronized Sufi saints. The most famous example is his relationship with the Naqshbandi Sufi order, particularly the saint Sayyid Baraka, who blessed his campaigns. In return, these scholars provided the theological cover he needed. They issued fatwas declaring his enemies apostates. Without that support, Tamerlane's religious campaigns would have lacked legitimacy. But other scholars, like the great historian Ibn Khaldun, saw right through it. Luna: Ibn Khaldun actually met Tamerlane, right? Lucas: Yes, in 1401, when Tamerlane was besieging Damascus. Ibn Khaldun was in the city and was lowered over the walls in a basket to negotiate with the conqueror. He spent several weeks in Tamerlane's camp, and he wrote about their conversations. Ibn Khaldun was deeply impressed by Tamerlane's intelligence and his interest in history and politics. But he also noted that Tamerlane was utterly ruthless and that his religious justifications were thin. In his autobiography, Ibn Khaldun describes Tamerlane as "a man who loved to argue about theology, but who had no real commitment to any school of thought." He saw Tamerlane as a pragmatist who used religion when it served him. Luna: So Tamerlane the 'Sword of Islam' was actually more like a politician in a turban? Lucas: In many ways, yes. But it's also important to note that Tamerlane was genuinely pious in his own way. He prayed regularly, he fasted, he gave alms. But his piety was intertwined with his Mongol heritage and his personal ambition. He believed he was divinely chosen — you see that in his title 'Sahib-i Qiran', which means 'Lord of the Auspicious Conjunction', implying he was born under a special planetary alignment that destined him for greatness. So he likely saw his conquests as a divine mission, but he was flexible about what that meant. Christians, Zoroastrians, and Hindus in his empire were generally left alone, as long as they paid the jizya tax. He even employed Christian engineers and Buddhist artists. But Muslims who opposed him were branded heretics and destroyed. That selectivity tells you a lot about his priorities. Luna: It reminds me of how the early caliphs dealt with apostasy — death penalty for leaving Islam, but tolerance for non-Muslims under certain conditions. Lucas: Exactly. Tamerlane was applying the classical Islamic law of apostasy, but he was stretching it to cover political opposition. And he had the scholars to back him up. But here's the thing: his religious campaigns also had a strategic dimension. By targeting Shia and heterodox groups like the Sarbadars and later the Hurufis, he was also weakening potential centers of resistance that were not aligned with his vision of a centralized Sunni empire under his control. He was clearing the board of any alternative power structures that could challenge his authority. Luna: And we should mention the economic side too, right? Looting religious sites was a huge source of wealth. Lucas: Absolutely. Every campaign brought in treasure to fund his building projects in Samarkand. The Bibi-Khanym Mosque, the Registan — they were built with the spoils of these so-called holy wars. So there was always a material incentive. But I think the religious justification was more than just window-dressing. Tamerlane was a man of his time. In the 14th century, legitimacy came from God — or from the Chinggisid lineage, which he lacked. So he leaned heavily on the religious card. And it worked. He built an empire that lasted after his death, in part because his successors, like his son Shah Rukh, continued the policy of patronizing Islam and using it to unite their diverse realms. Luna: It's fascinating how a single episode in history can reveal so much about the intersection of faith, power, and violence. Lucas: That's what keeps me coming back to Tamerlane. He's not just a conqueror; he's a case study in how ideology is molded to fit ambition. And I think if you're listening to these conversations with us, you probably appreciate that kind of depth. It's one of the reasons we can keep making this show — because listeners like you want to go beyond the headlines. Luna: And speaking of that — a quick honest thing. A handful of listeners chip in monthly through buy me a coffee dot com slash fexingo, and that's literally what funds making as many episodes as we do. No ads, no sponsors, just people who love history. Lucas: Yeah, it's been humbling. We get to spend time on the details that matter — like how Tamerlane's religious policies shaped the Timurid Renaissance — because of that support. So if you've been enjoying these deep dives, that's the way to keep them coming. Luna: Okay, back to the story. So after Baghdad, what was Tamerlane's next religious target? Lucas: He turned his attention to the Mamluk Sultanate, which he also accused of being illegitimate. But that's a whole other episode. For now, let's leave it at this: Tamerlane's religious wars were a masterful blend of pragmatism, piety, and propaganda — and they left a deep mark on the Islamic world, from the destruction of Baghdad to the rise of the Timurid cultural flowering in Samarkand.
