Eventually, indo-Europeans from central Asia invaded the valley and settled among the existing population. Many farmers and pastoralists moved into adjacent regions in the south and east, and, slowly, sand silt buried the ruins of the cities. But the Indus culture did not die.
Although the Indo Aryan languages of the new settlers from the west eventually prevailed, the indigenous Dravidian languages had a strong influence on their vocabulary grammar and pronunciation. The Hindu religion that crystallized in the 1st millennium BC combined elements introduced by the Indo Aryans with the earlier beliefs of the inhabitants of Indus Valley settlements such as Harappa. Today, many features of modern Indian life have their roots in the Indus civilization- the first great flowering of culture in the subcontinent.
