Why did Alexander the Great decide to turn back after he conquered Northern India?


This actually spells out his direct reason for actually entering India.  It was to secure the Persian Empire itself to its fullest extent.  When he arrived, he did just that and actually no more.  What he learned though was that any further extension of his power was completely unrealistic and simply foolhardy.  Recall that the geographical extent of India matches that of Europe to the Urals.  It took the British several generations to do exactly this...

Thus he needed to consolidate Persia.  Had he been able to create a unified Greek led empire, then further expansion may have come naturally.  That did not happen and it also may have simply been impossible.

What did happen soon released those Indian provinces he held.

Why did Alexander the Great decide to turn back after he conquered Northern India?

In order to understand why Alexander the Great decided to turn back after conquering Northern India, it is important to first look at his reasons for invading India. He invaded India for two reasons:

  1. To reconquer the Indian provinces of the old Persian Empire; Alexander the Great had been proclaimed a successor and avenger of the Great Kings of the Persian Empire. As such, he considered the old Persian Empire to be his by right of conquest. Since Northern India was a province of the Persian Empire, Alexander considered it to be his.
  2. To reach to the Ends of the World; Alexander, as his teacher Aristotle did, believed that the great Ocean was nearby: do remember that Alexander did not have modern maps like we have. He could not have known that the ‘great Ocean’ was still very, very far away and that there was a whole subcontinent between him and the sea. Alexander could not resist the temptation of going to the great Ocean. He could then claim to have reached the Ends of the World.   

  1. This map shows how Alexander the Great and the Greeks of that era viewed the world. As you can see, Alexander did not believe that his Indian campaign would be long; the sea was nearby and India wasn’t a very vast land. Things did not go according to plan, however:
  • His army, not being used to the tropical environment of India, was ravaged by diseases, constant rain due to Monsoons and snakes and other animals. We have to remember that the Macedonian army had been on campaign for almost 12 years. Many of them wanted to return to Macedonia and enjoy the fruits of victories instead of fighting in some distant land. They had already conquered the entire Persian Empire and already had enough wealth to live a luxurious life, so they did not see the reason to fight any further, especially under such conditions.
By the time the Macedonian army had reached the Hyphasis River, Alexander knew that beyond the Ganges River was the powerful Nanda Empire which had 200,000 infantry, 80,000 cavalry, 8,000 war chariots, and 6,000 war elephants. Alexander had only 40,000 infantry and 7,000 cavalry and his men were exhausted and on the brink of mutiny. Alexander also now knew that the great Ocean was very far away. He had already conquered the old Persian provinces in India and even more, so there was no reason to continue the campaign.
According to the ancient historians, the army mutinied at Hyphasis River and forced Alexander to turn back. However, some modern historians, with good reason, believe that Alexander may have staged or let the mutiny happen in order to justify his turning back from India without damaging his prestige. Alexander was no idiot; he knew that to continue the Indian campaign would be a madness and that the army would mutiny for real sooner or later. Whether the army really mutinied at the Hyphasis River or this was simply a PR stunt, Alexander turned back from India.

The legend is his army was exhausted and became rebellious:

East of Porus's kingdom, near the Ganges River (the Hellenic version of the Indian name Ganga), was the powerful Nanda Empire of Magadha and the Gangaridai Empire of Bengal. Fearing the prospects of facing other powerful Indian armies and exhausted by years of campaigning, his army mutinied at the Hyphasis River (the modern Beas River), refusing to march further east.

As for the Macedonians, however, their struggle with Porus blunted their courage and stayed their further advance into India. For having had all they could do to repulse an enemy who mustered only twenty thousand infantry and two thousand horse, they violently opposed Alexander when he insisted on crossing the river Ganges also, the width of which, as they learned, was thirty-two furlongs, [3 1/2 miles] its depth a hundred fathoms [600 feet], while its banks on the further side were covered with multitudes of men-at-arms and horsemen and elephants. For they were told that the kings of the Ganderites and Praesii were awaiting them with eighty thousand horsemen, two hundred thousand footmen, eight thousand chariots, and six thousand fighting elephants.
— Plutarch's Lives
Gangaridai, a nation which possesses a vast force of the largest-sized elephants. Owing to this, their country has never been conquered by any foreign king: for all other nations dread the overwhelming number and strength of these animals. Thus Alexander the Macedonian, after conquering all Asia, did not make war upon the Gangaridai, as he did on all others; for when he had arrived with all his troops at the river Ganges, he abandoned as hopeless an invasion of the Gangaridai when he learned that they possessed four thousand elephants well trained and equipped for war.
— Megasthenes, Indika
Alexander, using the incorrect maps of the Greeks, thought that the world ended a mere 1,000 kilometres (620 mi) away, at the edge of India. He therefore spoke to his army and tried to persuade them to march further into India, but Coenus pleaded with him to change his mind and return, saying the men "longed to again see their parents, their wives and children, their homeland". Alexander, seeing the unwillingness of his men, agreed and turned back.
