Explanation: The Early Harappan phase, known as the Regionalisation Era, was the formative, proto-urban phase of the Harappan civilization.

It is related to the Hakra phase of settlements, and the settlements in this period are marked by their fortification, a fairly high level of expertise in specialised crafts such as stone-working, bead-making, and metal-crafting, the use of wheeled transport, and the existence of trade networks.
