Sites such as Harappa continued to be inhabited and are still important cities today. . . . Late and post-Harappan settlements are known from surveys… - Jonathan Mark Kenoyer

There is evidence for the intensification of subsistence practice, multicropping and the adoption of new forms of transportation (camel and horse). These changes were made by the indigenous inhabitants, and were not the result of new people streaming into the re- gion. The horse and camel would indicate connections with Central Asia. The cultiva- tion of rice would connect with cither the Late Harappan in the Ganga-Yamuna region or Gujarat. (Kenoyer 1995, 227;)

The dating of glass in the Indus Valley and northern India, between 1900 and 1700 BC suggests that this industry was becoming common in all three regions at about the same time. ...No analysis of the recently discovered Late Harappan glass has been undertaken, but the styles of beads and the presence of a highly developed faience industry suggests that the Indus glass technology was an indigenous development.

Contrary to the common notion that Indo-Aryan speaking peoples invaded the subcontinent and obliterated the culture of the Indus people; we now believe that there was no outright invasion; the decline of the Indus cities was the result of many complex factors.
