Which ruler of the Delhi Sultanate introduced the silver 'Tanka' and copper 'Jital', establishing the standard monetary system of the Sultanate?

💡 Solution & Explanation

Iltutmish reformed the currency system of the Delhi Sultanate by introducing the silver Tanka and the copper Jital, moving away from indigenous coinage designs toward an Islamic monetary standard. Earlier rulers like Qutb-ud-din Aibak did not issue standard coins of this scale, while later monarchs built upon this foundation. The silver Tanka weighed approximately 175 grains and remained the standard coin of the Sultanate era.
