The histories of the early descendants of Manu portray the Harappan Civilization in its infancy. The changes in the archaeological strata of the Early-Harappan Civilization reflect such processes like Asura presence (Amri Culture), Aikṣvāku expansion (Rapid Spread of Kot-Diji Culture) and the decline of Aila power (Shrinking of Hakra Culture). The growth of the Aikṣvākus at the expense of the Ailas was aided by the local orthodoxy.
