Which Delhi Sultan is credited with establishing a separate department for slaves known as 'Diwan-i-Bundagan'?

💡 Solution & Explanation

Firuz Shah Tughluq created a dedicated administrative department named Diwan-i-Bundagan to oversee the maintenance and employment of his large retinue of enslaved individuals. Other Delhi Sultans like Iltutmish or Muhammad bin Tughluq established different administrative bureaus such as Diwan-i-Ariz or Diwan-i-Kohi, but did not institute this specific slave department.
