The ancient Indus civilization flourished along the Indus River valley from 2500 BCE to 1500 BCE. At its height, over 500 cities and settlements extended over 1,000 miles. The Indus cities of Harappa and Mohenjo-Daro were well-planned with gridded streets and advanced water and drainage systems. The Indus civilization engaged in extensive trade and had a literate population, though its writing remains undeciphered. The civilization declined rapidly around 1500 BCE, possibly due to flooding, drought, or invasion.
