His military and administrative innovations, while often harsh, demonstrated the capacity of Islamic governance to defend and administer a vast, diverse territory.

His market reforms are studied as an early experiment in state economic management — contributing to debates about price controls and command economies centuries later. His conquests in the Deccan opened South India to Islamic cultural influence, leading eventually to the great Deccan Sultanates and their contributions to Indo-Islamic art, archi…
