Q. Mongols under Genghis Khan invaded India under whose reign?
Answer:
Iltutmish
Notes: In 1221 A.D., Genghis Khan threatened India while pursuing Jalal-ud-din Mangbarni. Iltutmish chose diplomacy, denying asylum to Jalal-ud-din, which helped avoid a Mongol invasion and preserved the Delhi Sultanate. His strategic alliances and fortifications also protected the empire.
