The last phase of the Indus Valley Civilisation that lasted from c. 1900 to 1300 BCE and was preceded by the Early Harappan Phase (c. 3300–2600 BCE) and Mature Harappan Phase (c. 2600–1900 BCE). The period marks the gradual decline of the civilisation, with a breakdown of urban centres and the establishment of rural networks. Towards the end of the phase, most post-urban sites were abandoned. Important sites from this phase include Jhukar in Sindh and Rangpur in Gujarat.
