The advent of the Indus Valley Civilisation roughly dates back to about 5,000 years ago. More than 250 major centres of the Harappan civilisation have been discovered in different areas of the Indian subcontinent. According to reports, the civilisation may have extended from Jammu in the North to Gujarat in the South, and from Meerut in the East to the coast in the West. The Aryans, on the hand, migrated to the Indian subcontinent around 1,500 BCE.
