They Built This 4,000 Years Ago (Then Vanished)

They had flush toilets, city grids, and a government without kings—4,000 years before the rest of the world caught up. Then, they disappeared without a trace. In this episode of Era by Era, we uncover the mystery of the Indus Valley Civilization (Harappa and Mohenjo-daro). While Egypt was building pyramids for the dead, these people were building plumbing for the living. They mastered water engineering, created a writing system we still can't crack, and built a society that looks suspiciously modern. So why did a civilization of 5 million people vanish overnight? And why are we only just now rediscovering their secrets? *In this video, we cover:* The ancient city planning that rivals modern New York. The "impossible" plumbing system of 2500 BC. The mystery of the undeciphered Indus Script. The terrifying reason why they collapsed. *Subscribe for more history mysteries:* [Insert Link] #AncientHistory #IndusValley #MohenjoDaro #LostCivilizations #HistoryDocumentary #Archaeology #EraByEra
