Decline of Harappan Civilization

Key notes

The decline of the Harappan urban system occurred gradually after around 1900 BCE. It was not necessarily a single event or uniform process across all regions.[ncert.nic]

Main features of decline

  • Deurbanisation.
  • Decline of long-distance trade.
  • Disappearance of standardised urban features.
  • Reduced use of writing and seals.
  • Regionalisation of material culture.
  • Movement of populations toward smaller settlements.
  • Expansion toward the upper Ganga-Yamuna region and other areas.

Possible causes

Environmental changes

  • Changes in river courses.
  • Floods.
  • Droughts.
  • Climate change.
  • Decline in monsoon strength.
  • Water stress.
  • Ecological degradation.

Economic factors

  • Decline in external trade.
  • Disruption of raw-material supply.
  • Weakening of craft specialisation.
  • Collapse of urban redistribution systems.

Social and political factors

  • Weakening of central or regional institutions.
  • Internal stress.
  • Transformation of settlement patterns.
  • Conflict is possible but not conclusively established.

Migration and cultural transformation

  • Populations may have dispersed or migrated.
  • Late Harappan cultures continued in several regions.
  • There was no complete disappearance of Harappan traditions.
  • Many agricultural and craft practices continued.

Rejected or cautious theories

  • The old “Aryan invasion” explanation is not accepted as a sufficient explanation for the civilisation’s decline.
  • Evidence for widespread destruction is limited.
  • Decline was likely multi-causal and regionally varied.
