The Civilization That Vanished Without a Trace

4,000 years ago, the Indus Valley Civilization built cities with running water, perfect drainage, and grid-planned streets — while much of the world still lived in huts. Then, around 1800 BC, they mysteriously vanished. No war. No fire. No invasion. Just silence. Their script remains unreadable, their cities abandoned — and the truth behind their disappearance is still one of history’s greatest unsolved mysteries. 🏺🌍 #HistoryShorts #LostCivilizations #IndusValley #AncientMystery #UnsolvedHistory #MohenjoDaro #HistoryReel #AmazingHistory #AncientSecrets #WorldHistory #MindBlowingFacts #Archaeology
