Balban (reigned 1266–1287) further strengthened the administrative structure, but his reign is more associated with military reforms and centralization rather than financial measures like Diwane-e-Riyasat.
Ala-ud-Din Khalji (reigned 1296–1316) was known for his efficient administration and economic policies. He appointed the first Diwane-e-Riyasat, which significantly improved the state's financial management.
Qutub-ud-din Aibak (reigned 1206–1210) laid down the foundation of the Delhi Sultanate but did not implement such specific administrative measures.
