Iranian Invasion of India
- The Iranians invaded India in the 6th century B.C, when King Darius I ruled over Iran.
- He invaded India and occupied the territories in the North-Western Frontier Province, Sind and Punjab in 516 B.C.
- These parts remained with the Iranian Empire till Alexander’s invasion of India.
The Condition in India, at that time
- In north-east India, smaller principalities and republics gradually merged with the Magadhan Empire.
- North-west India, however, presented a different picture in the sixth century BC. Several small principalities, such as those of the Kambojas, Gandharas, and Madras fought one another.
- This area did not have any powerful kingdom like that of Magadha to weld the warring communities into one organized kingdom.
- Further, as the area was fertile and rich in natural resources, it attracted the attention of its neighbours. In addition, it could be easily penetrated through the passes in the Hindu Kush.
The Invasion
- The Achaemenian rulers of Iran, who expanded their empire at the same time as the Magadhan princes, took advantage of the political disunity on the north-west frontier.
- The Iranian ruler Darius penetrated north-west India in 516 BC and annexed the Punjab, west of the Indus, and Sindh.
- This area was converted into the twentieth province or Satrapy of Iran, which had a total number of twenty-eight satrapies.
- The ‘’Indian satrapy’’ included Sindh, the north-west frontier, and the part of Punjab that lay to the west of the Indus.
- Further, the Indian subjects were also enrolled in the Iranian army.
- Xerxes, Darius’s successor, employed Indians in the long war against the Greeks. It appears that India continued to be a part of the Iranian empire till its invasion by Alexander.

Conquest of Iranian empire to India
Impact of the Invasion on India
- Political impact
- Even though the invasion did not affect Indian Politics in any significant manner, it only exposed the weakness of the Indian Defense in that region and paved way for the conquest of Alexander.
- The Satrap system of administration introduced by Persians in Indian provinces, served as model to later dynasties especially the Sakas and Kushanas.
- Eventually, Indians learnt the necessity of strong and united empire to repel the foreign invasions.
- Encouragement to Trade
- The mutual contacts helped in the growth of trade between the two countries.
- The India Traders and merchants now reached distant places in the Vast Persian Empire to dispose of their goods.
- Similarly, the Persian goods began to flow smoothly into India.
- Settlement of Foreigners on Indian Soil
- A large number of foreigners, the Greek the Persians, Turks etc. settled down in the North –Western parts of India.
- With the passage of time they completely absorbed among the Indians.
- Impact on Art and Architecture
- The Iranian art also influenced the Indian art.
- Ashoka, followed the Iranian custom of preaching ideals by inscribing them on the stone pillars.
- The Indians also learnt the art of polishing.
- Interchange of Indo Persian culture
- Indian Scholars and philosophers went to Persia and exchanged their views freely with the intellectuals of that country.
- This contact brought about a great change in the outlook of the people and bought the people closer.
- Impact on Art and Architecture
- According to Megasthenes (Greek Ambassador at court of Chandragupta), the Mauryan ruler adopted certain Persian Ceremonies and rituals. Hence, the Mauryan art was influenced by the Persian art to some extent
- Asoka, followed Iranian custom of preaching ideals by inscribing them on the stone pillars. The Architecture of the period of Asoka was influenced by Persian Architecture
- Iranian influence may also be traced in the preamble to Ashoka’s edicts as well as in certain terms used in them. For instance, for the Iranian term dipi, the Ashokan scribe used the term lipi
- Kharoshthi script
- The Aramaic form of writing, which the Persians introduced in the North-Western India, after their conquest, gradually developed into the Kharoshti script, which is written from right to left
- All the Asokan rock inscription, in the North-West India were engraved in the Kharoshti script
- The idea of inscribing ethical exhortations on rocks, in form of royal proclamations might have been borrowed from Persia
- Influence on Coinage
- The Persian silver coins that were in circulation in India, were known for their refined minting and elegant looks.
- This had an impact, as Indian rulers adopted similar techniques to mint their coins on the Persian model.
Thus, the Iranian invasion led to certain lasting impacts. Also, it appears that through the Iranians, the Greeks learnt about the great wealth of India, which whetted their greed and led to Alexander’s invasion of India.
