Around 1150 AD Civilizations on FOUR Continents Collapsed Together - Nobody Connected Them

Get our book: https://sleepytimehistory.com Did four powerful civilizations on different continents really collapse around 1150 AD at almost the same time… without ever knowing each other existed? In this video, we investigate a strange twelfth‑century pattern: the crises of Chaco Canyon in North America, Tiwanaku in the Andes, the Ghana Empire in West Africa, and the Liao dynasty in East Asia. Were these collapses caused by a shared global climate disturbance, shifting trade networks, political breakdown, or is it all just a misleading coincidence? We break down archaeological dates, drought evidence, trade routes, and regional vulnerabilities, and ask what “collapse” actually means: disappearance, transformation, or later historians oversimplifying complex stories. Along the way, you’ll see how a world without a single global empire could still share surprisingly similar risks. If you’re interested in ancient history, climate change in the past, and why societies rise and fall, this deep-dive is for you. Subscribe to the channel for more historically grounded investigations into collapse, resilience, and the hidden connections that shaped our world.

We work as directors and editors, using AI tools to assist with research and drafting the script while we shape the narrative and verify the facts. The narration is delivered by a digital replica of a professional voice actor, and the visuals are individually crafted artistic impressions created with AI. Even with these tools, bringing a story of this depth to life takes many hours of work.
