Alexander Invasion (327-326 BC) and Its Impact on Ancient India

Alexander the Great’s invasion of India in 327-326 BC marked a significant event in ancient history, bringing Greek influence to the Indian subcontinent and influencing the region’s political dynamics and cultural exchanges.

Reason Behind the Invasion of India:

• Greek-Iranian Conflict: In the 4th century AD, the Greeks and Persians fought for world supremacy. After defeating the Persian army, the Macedonian conqueror Alexander marched towards India.
• Disunity in North-West India as it was divided into/with numerous independent monarchies and tribal republics like Taxila, Punjab (Kingdom of Porus), and Gandhara. Thus, the Khyber Pass remained unguarded, thus an accessible route for invaders.
• Wealth of India, as described by Greek writers like Herodotus. 

Alexander’s Campaign in India and Its Implications:

• Alexander’s invasion of India began in 326 BC (during Dhanananda’s reign) when he crossed Khyber Pass to enter India.
  • The Jhelum River marked the first strong resistance from Porus, an Indian prince. 
  • Although Alexander defeated Porus in the battle of Hydaspes (on the bank of Jhelum), he was impressed by Porus’s valour and restored his kingdom. 
• Alexander continued eastward up to the Beas River, but his army refused to go further due to the formidable power of Magadha, war-weariness, disease, and homesickness.
• Thus, Alexander was forced to retreat, ending his dream of an eastern empire. During his return, he died of typhoid in Babylon.
