Here’s a question that keeps me up at night: How does a tribe of 3,700 people—barely enough to fill a small college campus—go from zero to wiping out two hundred-year-old empires in 12 years?
Most people reach for the usual suspects: “Oh, Liao and Song were rotten to the core.” Or “Those Jurchen warriors must have had secret weapons.” But surface-level explanations are just comfort food for the brain. The real story is way more practical—and it has everything to do with how you structure a team when you have nothing to lose.
Think about it. Rome spent 250 years just to conquer Italy. The Mongol Empire took 45 years to bring down the Southern Song. Even the Qing, the Jurchen’s own descendants, needed 30 years to enter the Great Wall. Yet the Jin dynasty? 12 years flat. That’s not just luck—it’s a different species of organization.
Here’s the kicker: when Wanyan Aguda declared himself emperor in 1115, his kingdom wasn’t a kingdom at all—it was a startup. No bureaucratic layers, no pension systems, no “I’ve been here 20 years, where’s my promotion?” Just a group of people who knew that if they lost, they’d all die. Compare that to Liao and Song, where generals cared more about their rank than the mission. The difference isn’t firepower—it’s internal friction.
And guess what? This exact same dynamic plays out every day. A giant corporation sits on top of a mountain of resources, yet a 10-person startup can outmaneuver it. Why? Because small, hungry teams have zero internal drag. Everyone’s incentive is aligned with survival, not with protecting their corner office.
So the next time you feel outmatched by a bigger competitor, remember the 3,700. The real enemy isn’t size—it’s how well your organization can act as one. That’s the lesson from 1115, and it’s just as true today.
