The Deccan sultanates were five late-medieval Indian kingdoms—on the Deccan Plateau between the Krishna River and the Vindhya Range—that were ruled by Muslim dynasties: namely Ahmadnagar, Berar, Bidar, Bijapur, and Golconda. The sultanates had become independent during the break-up of the Bahmani Sultanate. In 1490, Ahmadnagar declared independence, followed by Bijapur and Berar in the same year. Golconda became independent in 1518, and Bidar in 1528.
