Hey there, night crew. Tonight we're tackling one of history's greatest vanishing acts,

an entire civilization that built towering pyramids, tracked the cosmos with terrifying accuracy,

and then just walked away. The Maya collapse. And no, aliens didn't do it,

the calendar didn't end the world in 2012, and they definitely didn't all mysteriously disappear

into thin air like some History Channel fever dream.

Where in the world are you watching from right now?

I always wonder who's joining me on these late-night history trips.

Now dim those lights, get comfortable,

and let's figure out what actually happened when one of the most advanced civilizations on

earth decided their magnificent cities weren't worth living in anymore. Here's the thing,

the Maya didn't vanish. They're still here, millions of them, but they're great cities. Those did collapse, and the

story of how and why is way more fascinating than any mystery-mongering documentary would have

you believe. Ready? Let's get into it. The last dated monument in the great city of Kapan was

erected on January 18, 822 CE. Someone carved that date into stone with the

confidence of a civilisation that assumed it would be around to read it centuries later. They were

wrong. By 900 CE, the city that had once housed tens of thousands of people was silent. The pyramid

still stood, the ball courts remained intact,

and the elaborate water systems continued to function exactly as designed, which was unfortunate

because there was nobody left to use them. It's like building the perfect smart home and then

moving out without telling anyone the Wi-Fi password. This is what archaeologists call the Terminal Classic period, though Terminal makes it sound

like the Maya showed up at an airport and never boarded their flight.
