Frequently Asked Questions

Who was King Porus?

King Porus was the Indian ruler who fought against Alexander the Great at the Battle of Hydaspes (Jhelum) in 326 BCE. Although he lost, Alexander was so impressed by his courage and dignity that he restored his kingdom and even expanded it.

Why did Alexander’s army refuse to march further east at the Beas River?

Alexander’s soldiers were exhausted after years of continuous campaigning. They also feared the massive war-elephant army of the powerful Nanda Empire of Magadha, which reportedly had around 6,000 war elephants. This led to the famous mutiny at the Beas River.

What was the long-term political impact of Alexander’s invasion on India?

By defeating the small independent kingdoms of the Northwest, Alexander created a political vacuum. This helped Chandragupta Maurya to rise and eventually unify much of India under the Mauryan Empire.

What is the significance of the Battle of Hydaspes?

The Battle of Hydaspes (326 BCE) was Alexander’s last major battle in India. Although he won a pyrrhic victory against King Porus, it marked the easternmost limit of his empire. The battle is famous for Porus’s use of war elephants and Alexander’s subsequent generous treatment of the defeated king.

How did Alexander’s invasion influence Indian art?

Alexander’s invasion led to cultural interaction between Greek and Indian traditions, which gave rise to the Gandhara School of Art — a unique style that blended Hellenistic (Greek) artistic features with Indian Buddhist themes.
