Ancient History › Religious Movements, Mahajanapadas and Foreign Invasions · Topic 5.13
Alexander of Macedonia entered India through the Khyber pass in 326 BC, took advantage of the disunity of the north-west, received the submission of Ambhi of Taxila, defeated Porus on the Jhelum, and turned back at the Beas when his army refused to go further. He stayed nineteen months, left three Greek governors and founded cities. His invasion opened land and sea routes, gave valuable geographical and historical accounts and paved the way for the Mauryas.

Where Does It Fit?
This is the last topic of the category on religious movements, Mahajanapadas and foreign invasions. The previous topic covered the Iranian invasion, and this one covers the Greek invasion. The next category begins with the sources of the Mauryan Empire. Previous topic: Iranian Invasion of North-West India and its Results.
Why Did Alexander Invade India?
In short: wealth, curiosity and ambition drew Alexander, and the disunity of the north-west made the conquest easy.
In the fourth century BC the Greeks and the Iranians fought for supremacy, and under Alexander of Macedonia the Greeks destroyed the Iranian empire. After conquering Asia Minor, Iraq and Iran, Alexander marched to India, attracted by its great wealth. Herodotus, the father of history, and other Greek writers had painted India as a fabulous land. Alexander also had a passion for geographical inquiry and natural history, had heard that the Caspian Sea continued on the eastern side of India, and was inspired by the mythical exploits of past conquerors whom he wanted to surpass. The political situation suited him: the north-west was parcelled out into many independent monarchies and tribal republics, strongly wedded to the soil and to their own principality, which he could conquer one by one. The two best-known rulers, Ambhi, prince of Taxila, and Porus, whose kingdom lay between the Jhelum and the Chenab, might together have resisted, but could not form a united front and the Khyber pass remained unguarded.
How Did the Campaign Unfold?
| Stage | Event |
|---|---|
| Approach | After Iran, Alexander moved to Kabul and marched through the Khyber pass in 326 BC; reached the Indus in five months |
| Taxila | Ambhi submitted readily, augmenting Alexander’s army and treasure |
| Jhelum | Strongest resistance from Porus, who was defeated but, impressed by his bravery, restored to his kingdom as an ally |
| Beas | Alexander advanced as far as the Beas; his army refused to go further |
| Return | Vanquished many small republics on the way back to the frontier |
| Stay | Nineteen months, 326 to 325 BC |
The Greek soldiers were war-weary and diseased, homesick after ten years of continuous campaigning in a hot climate, and had seen the fighting qualities of Indians on the Indus; the historian Arrian says the Indians were far superior in the art of war to the other nations in the region. They were also told of a formidable power on the Ganges, the kingdom of Magadha under the Nandas with an army far larger than Alexander’s. Despite his appeals the soldiers refused to advance, and the king who had never known defeat had to accept it from his own men. His dream of an eastern empire remained unfulfilled. Most conquered states were restored to their rulers who submitted to his authority; his own possessions were divided into three parts under three Greek governors, and he founded cities to hold the region.
What Were the Effects of the Invasion?
The invasion was the first occasion when ancient Europe came into close contact with ancient South Asia. Alexander added an Indian province much larger than that Iran had conquered, but the Greek possessions were soon lost to the Mauryas. Its most important outcome was the establishment of direct contact between India and Greece. The campaign opened four distinct routes by land and sea, helping Greek merchants and craftsmen and increasing trade facilities. Greek settlements multiplied in the north-west, notably Alexandria in the Kabul region, Boukephala on the Jhelum and Alexandria in Sindh. Though the Mauryas conquered the area, Greeks continued to live under Chandragupta Maurya and Ashoka.
| Effect | Detail |
|---|---|
| Geography | Nearchus sent with a fleet from the mouth of the Indus to the Euphrates; geographical accounts |
| Chronology | Clearly dated records of the campaign allow Indian chronology of later events to be fixed |
| Social information | Accounts mention sati, sale of girls by poor parents, fine oxen (200,000 sent to Macedonia), and flourishing carpentry |
| Political | Destruction of small states paved the way for Mauryan expansion; Chandragupta is said to have seen Alexander’s military machine |
As an analytical point, the campaign did not change India’s political structure in the way the Mauryas later did; its chief value is as a source of dating and as an episode of contact, and the dated Greek record makes the Mauryan chronology workable, as in Megasthenes Epigraphic source Ashokan edicts Literary Mudrarakshasa, Puranas, Buddhist and…">Sources for the Study of the Mauryan Empire. The earlier Iranian experience is in Iranian Invasion of North-West India and its Results, and Greek rule in the north-west later is in Indo-Greeks in North-West India.
