Indians often wonder how things would be, had the great centres of learning like Nalanda, Takshashila and Vikramshila would still be around, flourishing. These and more fell to the invaders from time to time, and only a small part of the glory exists today.
How would Indian civilization be different today had Nalanda University not been destroyed?
A simple, straight, innocent but incomplete answer would be -
Muhammad bin Bakhtiyar Khilji was a warrior with weapons, who upon encountering the mighty Nalanda, saw thousands of savants who intellectually were centuries ahead of anything he had experienced. Nalanda was using the formal Vedic systems of learning since 5th c. A.D., like Takshashila and Vikramshila. Khilji had two choices - bow his head, learn from them, exceed them in knowledge. Or, burn them down. In ca.1193 AD, he chose to end Nalanda. And had this monster not done so, this University would be better and bigger than the Harvards and Stanfords of this world. India would have had a big education brand to flaunt globally, and so on and so forth.
Modern day ruins of Nalanda, and a reconstruction of the University seal -
Khilji and the end of the Buddhist monks -
BUT Such an answer will be not only superficial, it will be a grave injustice to the ancient Indians who built a magnificent civilization second to none.
