Foreign Invasion During Ancient India
- There were two significant foreign invasions of the Indian Subcontinent:
- The Persian invasion can be dated back to 550 BC when Cyrus conquered India’s northwestern front.
- The Greek invasion began in 327 BC when Alexander conquered North-West India.
- These two incursions aided Indo-Iranian trade and commerce.
- In India, Iranian scribes brought the Kharosthi script, which was later employed in several Ashokan inscriptions.
- It was written in the Arabic style, from right to left.
Persian Invasions
- In the first half of the sixth century BC, North West India had a number of tiny tribal republics.
- There was no sovereign power to bring these feuding tribes together.
- The Achaemenid kings of Persia or Iran took advantage of the region’s political discord.
- Cyrus, the Achaemenid dynasty’s founder, and his successor Darius I acquired sections of Punjab and Sindh.
- It was thought to be the Achaemenid Empire’s most fertile and populous region. The Achaemenid army also included Indian subjects.
- Nearly two centuries were spent under Persian hegemony in northwestern India.
- There must have been regular contact between the two regions during this time.
- Skylax’s maritime mission most likely increased trade and commerce between Persia and India.
