800 years ago, in the year 1221, the great Mongol conqueror Genghis Khan stood victorious at the western bank of the Indus river with 50,000 soldiers, having just defeated Jalal-ad-Din, the Shah of Khwarazm.

Across the river lay the richest country in the history of the world: India.

All he had to do was cross the river. If he crossed the river, not only would he be able to kill his enemy, he would also have the opportunity to smash the Delhi sultanate and conquer the world’s richest country.

Instead, he turned back, spurning the heaven-sent, once-in-a-lifetime chance to conquer India.

His decision to not invade India has perplexed historians for centuries. It remains an enduring mystery to this day.

This video reveals the reasons for Genghis Khan's refusal to invade India.
