Early Harappan (Ravi, Kot Diji and Sothi-Siswal phases)
The formative stage of the Indus civilisation, when regional farming cultures of the Indus plain, Baluchistan and the Ghaggar-Hakra valley grew into walled towns with shared pottery styles, early signs, standard bricks and long-distance trade. It is known by phases named after sites: Ravi and Hakra Ware, Kot Diji in Sindh and Punjab, and Sothi-Siswal on the Ghaggar.
Around 2600 BCE these merged into the Mature Harappan civilisation. From about 3000 BCE the map shows the Indus civilisation as a state.
