The Indus Valley civilization flourished around 3300-1300 BCE along the Indus River valley in modern-day Pakistan and northwest India. It included large urban settlements like Mohenjo-Daro and Harappa that had advanced sewage and drainage systems. While the exact reasons are unknown, the civilization began to decline around 1900 BCE, with many urban centers abandoned.
