The Mongol Diet: Fuel Behind Conquest

“Milk and meat—that’s all they eat?”
That incredulous comment came from Bhola, my long-suffering domestic help, as he peered over my shoulder at a passage I’d highlighted in a 13th-century Persian chronicle. “Sir, I’ve seen street dogs eat better than that.”
To which I replied, “Ah, but Bhola, those very milk-and-meat eaters conquered half the known world.”

Let’s be honest. When most people think of the Mongols, their minds leap to Genghis Khan thundering across the steppe, not to fermented mare’s milk or boiled mutton. But, as any historian worth his salt (or salted horse jerky) will tell you, the Mongols didn’t just win with swords and siege tactics—they won with their stomachs. Or more precisely, with what they could survive eating… and what their enemies couldn’t stomach even hearing about.

So pull up a stool, pour yourself a cup of salted yogurt tea (if you dare), and let’s dig into the diet that terrified civilizations from the Persian plateau to the gates of Vienna.

The Steppe as Pantry

“To understand a people,” my old mentor used to say, “first look in their kitchen.”
Well, the Mongols didn’t have kitchens—at least not in the way the Persians or Chinese did. They had yurts, fires, pouches of dried curds, and guts lined with blood sausage. Their pantry was the living steppe, and their menu was minimalist, mobile, and—by medieval standards—utterly horrifying.

Consider this: most Mongol warriors could go days without cooking a proper meal. Their horses provided everything—transport, milk, blood (yes, blood), and occasionally meat. In a pinch, a warrior would nick a vein in his horse’s neck, collect the warm blood in a leather cup, mix it with milk or water, and drink.
Bhola nearly fainted when I told him this. “Sir, if I tried that with our cow downstairs, the society secretary would call the police.”

And yet, this blood-milk cocktail wasn’t just survival—it was sustenance. High in iron, protein, and sheer willpower. Mongol warriors could ride 100 kilometers a day with nothing but dried meat, curds, and fermented mare’s milk, known as airag. It’s slightly alcoholic, fiercely sour, and smells like something that crawled out of an unloved cheese wheel. And yet it was considered a delicacy—and a disinfectant.

Why It Scared Everyone

Now imagine you’re a well-fed Persian courtier, sipping sherbet beneath a fig tree, when news arrives that a Mongol horde is approaching. You’re told they drink horse blood and chew on dried goat meat like tobacco. You look down at your saffron pilaf and suddenly lose your appetite.

This wasn’t just culinary culture shock—it was psychological warfare.

While the Mongols were feasting on boiled organs and hard cheese, their enemies were used to food that required fields, ovens, spices, and servants. They needed infrastructure. The Mongols needed a knife and a fire. Maybe just a knife.

There are accounts—some exaggerated, no doubt—of Mongol warriors boiling meat in their enemies’ helmets. Of them using the fat from horses or camels to cook bread on their shields. One Persian source even claimed that Mongols would throw whole animals into pits and roast them alive.
Bhola insists this is where tandoori came from. I told him to stop slandering Mughal cuisine.

The Enemy’s Weak Stomach

Here’s the genius: the Mongols didn’t have to win every battle. They just had to last longer. Their diet gave them that edge.

A European army, marching into the steppes with wine and bread carts, would crumble within weeks. No harvests, no bakeries, no spice merchants. Meanwhile, the Mongols could live off their horses, their herds, and the wind.

More than one chronicler noted how bewildering it was to fight men who didn’t need supply chains. “They carry their food with them,” wrote one frightened Polish scribe, “in leathern bags, and they eat it as if it were a feast.”
Imagine thinking you’ve cut off the enemy’s grain routes, only to find they’ve just slaughtered a yak and are throwing a celebratory feast.

It’s like trying to starve a cactus.

A Mobile Protein Factory

Each Mongol warrior rode with several horses—not just for backup transport but as moving meal kits. Horse milk (especially from mares) was turned into airag. Goats and sheep followed the camps like protein on hooves. Nothing went to waste: liver, tongue, heart, marrow, even bones were cracked open and boiled.

They carried dried cheese curds (called aaruul), which were so hard they had to be sucked for hours to soften. One Western knight reportedly broke a tooth trying them.
Bhola asked me if this was medieval protein bar. I said yes—except it doubled as a missile in a pinch.

And then there was borts—thin slices of meat (usually horse or goat) dried in the sun and crushed into powder. Just add water, and voilà: instant nomadic stew.
Try doing that with your biryani.

Culinary Superiority Complex

Now, the irony is that many Mongols saw their diet not as barbaric, but superior. They mocked the sedentary Chinese for their elaborate banquets, and the Persians for their flowery confections. Food, to them, was meant to sustain life and conquest—not to pamper the tongue.

When Genghis Khan’s descendants ruled over China, they reluctantly adopted aspects of Chinese cuisine—but with resentment. Kublai Khan, for example, maintained separate kitchens: one Mongol (meat-heavy, boiled), one Chinese (vegetable-based, steamed). Guess which one he ate from during war councils?

Even today, modern Mongolian cuisine retains echoes of its past—think buuz (steamed meat dumplings), khorkhog (meat cooked with hot stones inside a metal canister), and endless variations of dairy products.

The Psychological Effect of a Menu

Imagine, if you will, an invading army that not only destroys your defenses but turns your grain silos into smoking meat pits. That wears clothes soaked in fermented milk. That drinks the blood of its own transport. That doesn’t need your city’s riches—just a goat and a fire.

It wasn’t just their tactics that terrified the world. It was their indifference to comfort. The message was clear: “We don’t need what you have. We bring our own chaos.”

As one Persian poet lamented:
“They eat from their knives and drink what would make a drunkard gag.
And yet they ride like thunder and strike like gods.”

Final Bite: Why It Still Matters

So why does this matter today, you ask? Why should Bhola—or anyone—care what Genghis Khan had for breakfast?

Because diet, dear reader, is power. Always has been.

The Mongols’ ability to sustain themselves with minimal resources reshaped the world map. Their stomachs were their supply lines. Their culinary resilience was military genius in disguise. And their menu—raw, fermented, unapologetically unrefined—was a statement.

It said: “We can thrive where you starve. We can endure what you cannot even smell.”

And that, perhaps more than any sword or strategy, is why the world trembled before them.

Bhola, for the record, still refuses to try airag.
But last week I caught him eyeing a packet of borts on my bookshelf.
Curiosity, after all, is the first step toward conquest.
