Nizam-ul-Mulk, Asaf Jah I, appointed as Governor of the Entire Deccan region, including Central India and Gujarat up to Kanyakumari.

Later, his son, Nawab Amir Nawazul Mulk Bahadur, ruled successfully, displaying generosity by donating gold to compensate for a theft from Tulja Bhawani Temple.

Following the Nawab's demise, his successors governed until 1948, with the current heirs residing in Hyderabad, Telangana, showing sentimental attachment to Naldurg and its people.

Strategically located en route from Solapur to Bijapur-Bidar, the fort boasts medieval architecture and engineering techniques, reflecting the era's signature styles.
