A series of severe, decades-long droughts ushered the end of the Indus Valley Civilization, one of the world's oldest civilizations, a new study finds.
This Indus Valley Civilization (also known as the "Harappan" civilization) flourished between 5,000 and 3,500 years ago in a region that stretched across the modern-day India-Pakistan border. Its people created cities, such as Harappa and Mohenjo Daro, which had sophisticated water-management systems. They also created a written script, which remains undeciphered by modern scholars, and they traveled to Mesopotamia, where they conducted trade.
