Centered on cities like Mohenjo-daro and Harappa in the Indus River basin, this Bronze Age civilization built grid-planned streets and covered drainage systems well before comparable urban infrastructure appeared elsewhere.
Background
At its height the civilization covered a larger area than contemporary Egypt or Mesopotamia, with standardized weights, brick sizes, and city layouts suggesting a high degree of coordination across settlements.
“Some of history's earliest city planners left messages that still cannot be read.”
The Key Events
Thousands of short inscriptions survive on seals and pottery, but the script has never been definitively deciphered, and scholars still debate whether it represents full language or another kind of symbolic system.
Legacy and Lasting Impact
The civilization declined gradually around 1900 BCE, likely due to shifting river courses and climate change rather than sudden collapse. Its cities remain a benchmark for early urban planning studied by archaeologists today.
- Mohenjo-daro featured covered drains along most of its streets.
- The Indus script's inscriptions are typically very short, rarely more than a few symbols.
- The civilization's territory was larger than that of ancient Egypt or Mesopotamia.
