Latest / Trade Routes That Changed Human History Forever — Fexingo History / The Khazar Khaganate and the Silk Road Slave Trade
Transcript
- Lucas: So we've talked a lot about the Silk Road's east-west connections — the Sogdians, the Mongols, the spices from India. But there's a whole northern arc that we haven't really touched, and it's one of the darkest parts of the story: the slave trade that ran through the Khazar Khaganate. Luna: The Khazars — I've heard the name, but I don't know much about them. Weren't they the ones who converted to Judaism? Lucas: Exactly right. The Khazar Khaganate was a Turkic empire that controlled a huge swath of what's now southern Russia and Ukraine, from about the 7th to the 10th centuries. Their heartland was between the Volga and Don rivers, with capital cities like Itil on the Volga delta and Samandar in the Caucasus. And yes, around the 8th or 9th century, the ruling elite converted to Judaism — probably as a way to stay independent from both Christian Byzantium and the Muslim Caliphate. Luna: That's a fascinating political move. But you said slave trade — how did that tie into their economy? Lucas: It was central. The Khazars sat at a crossroads where they could raid or tax the flow of captives from Eastern Europe — Slavs, Finns, Balts, even some Vikings — and sell them south into the Islamic world. Arabic sources use the term 'sakaliba' to refer to Slavic slaves, and they were highly prized in Baghdad, Cordoba, and other Muslim cities. The Khazars didn't just trade slaves themselves — they also collected duties from merchants who passed through their territory. Luna: So they were like gatekeepers of a human traffic highway. Lucas: Exactly. And they weren't the only ones involved. There's a famous group of Jewish merchants called the Radhanites — they operated from the 8th to 10th centuries, traveling between Europe, North Africa, and Asia. They spoke multiple languages and had networks that could move slaves, textiles, spices, and other goods across enormous distances. The Khazars, being Jewish themselves, likely had close ties with these Radhanites. Luna: Were the Radhanites Khazar Jews, or were they from elsewhere? Lucas: Most scholars think the Radhanites were mostly Persian or Babylonian Jews, not Khazars. But they certainly did business with the Khazars. The 9th-century Persian geographer Ibn Khordadbeh actually describes four main trade routes of the Radhanites, and one of them goes right through Khazar territory — from the Rhône valley in France, through Prague, then down the Volga to the Caspian Sea, and eventually to Baghdad. Slaves were a major part of that trade. Luna: So the Khazars were both traders and raiders. How did they get the slaves in the first place? Lucas: They conducted raids into Slavic lands — what's now Ukraine, Belarus, and western Russia. They also demanded tribute from subject peoples in the form of slaves. For example, the 10th-century Arab historian al-Mas'udi says the Khazars regularly raided the Slavic tribes around the Dnieper River. Sometimes they'd capture people themselves; other times they'd buy captives from Viking bands who were raiding along the rivers. Luna: It's grim. But it sounds like this trade was a huge part of the early medieval economy. Lucas: Absolutely. The slave trade was arguably the most valuable commodity on the northern Silk Road. A single slave could fetch a huge price — especially young women and eunuchs, who were in demand in harems and households across the Islamic world. The Khazar khagan himself took a 10% tax on all goods passing through his realm, including slaves. That tax, plus the direct raiding, made the Khazars one of the wealthiest states in Eastern Europe. Luna: And their conversion to Judaism — did that affect their trade relationships? Lucas: It probably helped them maintain neutrality. They were sandwiched between two great powers: the Byzantine Empire to the west, which was Christian, and the Umayyad Caliphate to the south, which was Muslim. By adopting Judaism, they didn't have to ally with either side. And it gave them a natural connection to Jewish merchant networks like the Radhanites, who were spread all across Eurasia. So in a way, their religious choice was a trade strategy. Luna: That's clever, but also risky. Didn't it isolate them eventually? Lucas: It did, especially as the balance of power shifted. In the 10th century, the Kievan Rus' — a Viking-influenced state centered on Kiev — began to grow stronger. The Rus' had their own trade routes and ambitions, and they didn't like the Khazars controlling the Volga. Around 965, the Kievan prince Sviatoslav I launched a massive campaign against the Khazars. He sacked the capital Itil and the fortress of Sarkel, and essentially destroyed the Khazar state. Luna: Wait — Sviatoslav? That's the same prince who later fought the Byzantines, right? Lucas: That's the one. He's a fascinating figure — he spent most of his reign on horseback, campaigning. After crushing the Khazars, he did turn on Byzantium, but he was eventually defeated. The Khazar Khaganate never recovered. Some remnants survived in the Crimea and the Caucasus for a couple more centuries, but as a major power, they were gone. Luna: So what happened to the slave trade after the Khazars fell? Lucas: It didn't stop — it just shifted. The Rus' took over the Volga route, and they continued selling slaves to the Islamic world. But the Khazars' collapse really opened the door for new powers. The Cumans, the Pechenegs, and later the Mongols all played similar roles. The slave trade on the Silk Road continued for centuries — it was a constant, brutal undercurrent of the medieval economy. Lucas: And it's a reminder that when we talk about trade routes, we can't just think of silks and spices. Human beings were moved as commodities, and the Khazars were one of the key players in that system. Luna: It's a sobering angle. But it's important to understand how integral slavery was to these networks. Lucas: Exactly. And I think that's one of the reasons the Khazars have been somewhat overlooked in popular history — people prefer the romantic Silk Road of Marco Polo and Buddhist monks. But the reality was often much harsher. Luna: On that note — I know we've been doing this for a while, and I just want to say, if listeners are getting something out of these deep dives, it's worth considering tossing a couple of dollars a month toward the show. We keep it ad-free because of people like that. Lucas: Yeah, honestly, a small amount really does make a difference.

Luna: Exactly. No pressure, but it's appreciated. Lucas: So back to the Khazars — one more thing I find really interesting: their conversion to Judaism wasn't just a top-down thing. There's a famous letter from the Khazar king Joseph to a Spanish Jewish diplomat, Hasdai ibn Shaprut, in the 10th century. In it, Joseph describes how the Khazars adopted Judaism after a debate between a Jew, a Christian, and a Muslim. Whether that story is literally true or not, it shows how they saw their own identity as a deliberate choice. Luna: A debate — that's almost like a medieval interfaith dialogue. Do we have any other sources from the Khazars themselves? Lucas: Very few. Most of what we know comes from outsiders: Byzantine chroniclers, Arab geographers, and a handful of Hebrew letters. The Khazars left almost no archaeological traces that we're certain are theirs — no distinct material culture. That's partly why there's so much debate about them. Some historians even question how widespread Judaism really was among the Khazars — it might have been limited to the elite. Luna: So even their identity is kind of a mystery. That makes them even more intriguing. Lucas: It does. And the fact that they sat at such a crucial intersection — between Europe and Asia, between Christianity and Islam — makes them a fascinating case study in how trade, religion, and power all intersect. The Khazars show that the Silk Road wasn't just a single route; it was a web of connections, and some of the most profitable threads were the darkest ones.
