Hook and explanation of Persian and Greek adaptations of Sindhu.
Most foreign names for India originally derived from the Sindhu (Indus) River. In the 6th century BCE, a Persian emperor launched a military campaign and gained control of the Indus region.
Because of how their language worked, the Persians adapted the word 'Sindhu' into 'Hind', 'Hidu', or 'Hindu' in their earliest records and stone inscriptions.
