Bahmani Sultanate
The Prabalgad Fort was built by the Bahmani Sultanate to keep an eye on the Panvel Fort and the Kalyan Fort in the North Konkan area. Around 1458 A.D, "Malik Ahmad" the prime minister of the kingdom of Ahmednagar, took over the fort during his conquest of Konkan. After disintegration of the Bahmani Sultanate, the fort remained with the Ahmadnagar Sultanate.
