- Lucas: So we've covered silk, spices, porcelain, paper — the glamorous stuff. But there's one commodity that's older than all of them, more essential, and honestly just as fascinating. Salt. Luna: White gold. Lucas: Exactly. And while we tend to think of salt as just something on our table, for most of history it was literally worth its weight in gold. The word 'salary' comes from Latin salarium, the allowance Roman soldiers got to buy salt. And the Via Salaria — the Salt Road — was one of the oldest Roman roads, built to carry salt from the salt pans at Ostia inland. Luna: So the very word 'salary' ties back to this one route. Lucas: It does. And that's just Rome. In West Africa, salt was so valuable that for centuries it was traded ounce for ounce for gold. The Mali Empire, under Mansa Musa in the 14th century, controlled some of the richest salt mines in the world — especially at Taghaza and later Taoudenni. Caravans of hundreds of camels would carry slabs of salt across the Sahara to Timbuktu and beyond. Luna: 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 this many of these. So if you've been stepping into history with us episode by episode, that's the engine. Lucas: Yeah, it's a small group, but it keeps the whole thing ad-free and independent. Really appreciate it. Luna: Alright, back to the salt. So Mansa Musa's salt caravans — how big were they? Lucas: Contemporary accounts talk about caravans of 12,000 slaves carrying gold and salt, though that number might be exaggerated. But the salt trade was massive. The mines at Taghaza were literally built from salt blocks — the whole town was made of salt. When the Moroccan traveler Ibn Battuta visited in 1352, he described houses made of salt slabs, with camel-skin roofs. Luna: A town made of salt — that's incredible. Lucas: And the salt itself came in slabs about two feet long and an inch thick, carried on camels across the Sahara. The Azalai — the annual salt caravan — still runs today from Timbuktu to the Taoudenni mines, though on a smaller scale. The Tuareg have been guiding these caravans for centuries. Luna: What made salt so valuable there? Lucas: In West Africa, salt was a dietary necessity. People needed it to prevent dehydration and to preserve food. But there were no local salt deposits, and the climate made extraction difficult. So it had to come from the Sahara. And the empires that controlled those mines — Ghana, Mali, Songhai — they got rich taxing the trade. Mansa Musa's famous pilgrimage to Mecca in 1324, where he gave away so much gold it crashed the Egyptian economy — that was funded partly by salt. Luna: So salt literally bankrolled the richest man in history. Lucas: It did. But salt wasn't just an African story. In Europe, the Venetian Republic built its early wealth on salt. Venice had a monopoly on salt production in the Adriatic, and they controlled the salt trade throughout the Mediterranean. The Venetian galleys that carried crusaders to the Holy Land often returned laden with salt. Luna: And salt was crucial for preserving fish, right? For Lent? Lucas: Exactly. The Catholic Church's demand for salted fish during Lent created a massive market. Venice supplied salt to the whole of northern Italy and beyond. They even forced cities like Padua and Verona to buy their salt — it was a state monopoly. And in China, the Tang dynasty had a state salt monopoly that funded much of its military expansion. By the 8th century, salt taxes made up half of the Tang government's revenue. Luna: Half of the government's income from one thing? Lucas: Half. And that led to smuggling on a massive scale. The Tang government had to deploy troops to patrol salt routes and arrest smugglers. Some of those smugglers became folk heroes — like the salt smugglers of the Huai River who were celebrated in local ballads. But the most dramatic salt-related event was probably the French Revolution. The gabelle — the hated salt tax — was one of the most resented impositions of the Ancien Régime. Luna: The gabelle. I've heard that word — it's the salt tax, right? Lucas: Yes. The gabelle varied by region — some areas paid a lot, some paid nothing, which drove smuggling and resentment. When the Revolution came, the abolition of the gabelle was one of the first demands of the Third Estate. And in 1790, the National Assembly finally abolished it. The salt tax was gone, but the memory of it fueled revolutionary fervor. Luna: So a humble mineral helped bring down a monarchy. Lucas: In a way. And salt played a role in the American Revolution too. The British blockade disrupted salt imports, which were essential for preserving food. The Continental Army had to establish salt works, and some of the first acts of the Continental Congress dealt with salt supply. So salt has been at the center of some of history's biggest turning points — from the rise of empires to revolutions. Luna: It makes you think — every time you shake salt on your food, you're touching history. Lucas: Exactly. It's a reminder that the most ordinary things often have the most extraordinary stories.
