" There were several developments in different parts of the subcontinent during the long span of 1,500 years following the end of the Harappan civilisation. This was also the period during which the Rigveda was composed by people living along the Indus and its tributaries. Agricultural settlements emerged in many parts of the subcontinent, including north India, the Deccan Plateau, and parts of Karnataka. Besides, there is evidence of pastoral populations in the Deccan and further south.
