The Ancient City That Vanished Overnight (And Nobody Knows Why)

One day, a city of 30,000 people just stopped. No war. No fire. No plague anyone can prove. It was bigger than London or Paris at the time — and you've probably never heard its name. In this video, you'll discover Cahokia, the largest city in North America before Columbus, hidden just outside modern St. Louis. You'll learn how it rose almost overnight, why archaeologists still can't fully explain its collapse, and how drought, deforestation, and human tension may have quietly unraveled it. By the end, you'll see why this 900-year-old mystery is really a mirror held up to every modern city.
