Iranian Invasion of North-West India and its Results

Ancient History › Religious Movements, Mahajanapadas and Foreign Invasions · Topic 5.12

Taking advantage of the disunity of Kambojas, Gandharas and Madras, the Achaemenian ruler Darius annexed the Punjab west of the Indus and Sindh in 516 BC, making it the twentieth satrapy, paying 360 talents of gold. The contact lasted about 200 years and brought the Kharoshthi script, Iranian influence on Mauryan sculpture and edicts, and Indo-Iranian trade, though not punch-marked coins.

Where Does It Fit?

This is the twelfth topic of the category on religious movements. The previous topic covered society and the state, and this one covers the Iranian invasion. The next topic covers Alexander’s invasion. Previous topic: Varna System, Social Orders and Legislation in the Age of the Buddha.

Why and How Did Iran Invade?

In short: the disunited principalities of the north-west and the passes of the Hindu Kush invited Iranian conquest.

In north-east India, smaller principalities and republics gradually merged into the Magadhan empire. The north-west presented a different picture in the sixth century BC. Several small principalities, such as those of the Kambojas, Gandharas and Madras, fought one another, and there was no powerful kingdom like Magadha to weld them together. The area was fertile and rich and could be easily penetrated through the passes of the Hindu Kush. The Achaemenian rulers of Iran, who expanded at the same time as the Magadhan princes, took advantage of this disunity. Darius penetrated north-west India in 516 BC and annexed the Punjab west of the Indus and Sindh. The area became the twentieth province, or satrapy, of Iran, which had twenty-eight in all. The Indian satrapy comprised Sindh, the north-west frontier and the Punjab west of the Indus; it was the most fertile and populous part of the empire and paid a tribute of 360 talents of gold, one-third of the total revenue Iran received from its Asian provinces. Indians were enrolled in the Iranian army, and Xerxes employed them in the long war against the Greeks. India seems to have remained a part of the Iranian empire until Alexander.

How Did North-West and North-East India Differ?

The comparison with the Magadhan experience is instructive. In the north-east, iron-based agriculture, towns and a succession of strong rulers drew smaller principalities and republics into a single large empire, as seen in Rise and Growth of the Magadhan Empire. In the north-west, fertile land and natural resources existed but no ruler was strong enough to unify the Kambojas, Gandharas and Madras, who fought each other. The region’s wealth, together with the ease of crossing the Hindu Kush passes, made it the natural target for the Achaemenian expansion that was taking place at the same time as Magadha’s.

The annexation also placed the area within a vast imperial system. As a satrapy it paid a heavy tribute in gold and supplied soldiers; Indians fought in the Iranian army under Xerxes in his long war against the Greeks. Because the area remained within the Iranian empire for about two hundred years, officials and scribes of the empire were present, and this explains the arrival of the Kharoshthi script. The large Persian demand on the satrapy also shows how much wealth the north-west produced, a fact that the Greeks noted and later exploited.

What Were the Results of the Contact?

The Indo-Iranian contact lasted about 200 years and gave an impetus to trade and commerce between the two. The cultural results were more significant.

Result	Evidence
Script	Iranian scribes brought a form of writing, the Kharoshthi script, written right to left like Arabic; some Ashokan inscriptions in the north-west in the third century BC use it; used in India till the third century AD
Coins	Iranian coins found on the north-west frontier, showing exchange; but punch-marked coins did not come from Iran
Art	Iranian influence on Mauryan sculpture; Ashoka’s bell-shaped capitals owe something to Iranian models
Edicts	Influence on the preamble and certain terms; Iranian dipi became lipi
Greek interest	Through Iranians, Greeks learnt of India’s wealth, which whetted their greed and led to Alexander’s invasion

As an analytical point, the contact was political and cultural more than economic: the annexation was limited to the north-west, while Magadhan power grew in the east, a contrast that explains why the region later fell so easily to Alexander in Alexander’s Invasion and its Effects. The scripts of the period are discussed in Inscriptions as a Source of Ancient Indian History, and the art influence in Mauryan Art and Architecture.

Frequently Asked Questions

When did Darius annex north-west India?

Darius, the Achaemenian ruler of Iran, penetrated north-west India in 516 BC and annexed the Punjab west of the Indus and Sindh, converting the area into the twentieth satrapy of an empire that had twenty-eight satrapies.

How much tribute did the Indian satrapy pay?

The Indian satrapy paid a tribute of 360 talents of gold, which accounted for one-third of the total revenue Iran received from its Asian provinces, and it was the most fertile and populous part of the empire.

What is the Kharoshthi script?

Kharoshthi is a script brought by Iranian scribes into India, written from right to left like Arabic. Some Ashokan inscriptions in north-west India of the third century BC use it, and it continued in India until the third century AD.

Did the Iranians introduce coinage to India?

It is wrong to think that punch-marked coins came into use in India as a result of contact with Iran. Iranian coins have been found in the north-west frontier region, which points to exchange of goods, but the earliest Indian coinage developed in the Gangetic plains.

How did Iranian contact influence Mauryan India?

Iranian influence is visible in Mauryan sculpture, especially the bell-shaped capitals of Ashoka's monuments, and in the preamble and certain terms of Ashoka's edicts, such as lipi derived from the Iranian dipi, along with other points of Iranian preambles.
