Which of the following Delhi Sultanate rulers established the new administrative department known as Diwan-i-Kharaj for managing agricultural revenue?

💡 Solution & Explanation

Ala-ud-din Khilji instituted stringent revenue reforms, establishing the Diwan-i-Mustakhraj to investigate arrears and recover outstanding revenues from corrupt revenue officials. Plausible wrong options like Firoz Shah Tughluq established departments for welfare and employment such as Diwan-i-Bundagan and Diwan-i-Khairat, but revenue recovery fell under Khilji specialized administrative overhaul. This centralization helped him maintain a massive standing army without increasing taxes arbitrarily.
