Which Delhi Sultan established the department of 'Diwan-i-Ariz', dedicated entirely to maintaining, inspecting, and organizing the military forces of the realm?

💡 Solution & Explanation

Sultan Ghiyas-ud-din Balban established the Diwan-i-Ariz to overhaul the military administration and safeguard the Sultanate against external invasions and internal rebellions. Ala-ud-din Khilji later expanded upon this by introducing cash salaries and the branding of horses known as DagH. Iltutmish organized the original Iqta system, whereas Firoz Shah Tughlaq focused on public welfare and canal construction.
