In which reign Mongols were seen on the Bank of Indus river for the first time?

Correct option is B

The correct answer is (b) Iltutmish

Explanation:

• In 1221 AD, the Mongol leader Genghis Khan reached the banks of the Indus while pursuing Jalal-ud-din Mangabarni, the ruler of Khwarezm.
• Mangabarni sought asylum from Iltutmish, the Sultan of Delhi.
• Iltutmish diplomatically refused the request, stating that the climate of Delhi would not suit Mangabarni.
• This wise decision saved the Delhi Sultanate from the wrath of the Mongol invasion at that early stage.
• The Mongols eventually withdrew without crossing the Indus into the Sultanate.

• Iltutmish is considered the real founder of the Delhi Sultanate.
• He introduced the Iqta system and the Tanka/Jital coins.

• Daughter of Iltutmish; Mongol threats continued during her time but the first appearance was earlier.

• The founder of the Slave dynasty; Genghis Khan had not yet reached the Indian borders during his reign.

• He established a separate department (Diwan-i-Arz) to deal with the Mongol menace, but he reigned much later than the first appearance.
