Which Sultan of Delhi established the dedicated administrative department for royal slaves known as 'Diwan-i-Bandagan'?

💡 Solution & Explanation

Firoz Shah Tughlaq established the specialized department called Diwan-i-Bandagan to oversee the welfare, maintenance, and employment of the extensive population of royal slaves amassed during his reign. Other Sultans like Alauddin Khalji or Balban created distinct administrative bodies for military organization or revenue control rather than slave management. This welfare institution reflected the unique administrative and social priorities of the Tughlaq ruler.
