Phases of Indus Valley Civilisation

Pre-Harappan Phase (7000-3300 BC)

Early Harappan Phase (3000-2600 BC)

  • Emergence of several urban features like town planning, scripts and metal technology. Important sites include Kot Diji, Amri, Kalibangan, Dholavira.

Mature/Urban Harappan Phase (2600-1900 BC)

  • Full growth of urban economy and society. Important sites: Mohen-jo-Daro, Harappa, Lothal, Kalibangan, Dholavira, Ganweriwala, Rakhigarh etc.

Late Harappan Phase (1900-1300 BC)

  • Gradual collapse of urban character and towards the end of this phase IVC disappeared. Sumerian records ceased to mention trade with Meluhha.
