The Deccan sultanates were five dynasties of various ethnic backgrounds (Afghan, Turk, Mongol etc.) that ruled late medieval kingdoms, namely, Bijapur, Golkonda, Ahmadnagar, Bidar, and Berar in south-western India. The Deccan sultanates were located on the Deccan Plateau, between the Krishna River and the Vindhya Range. These kingdoms became independent during the breakup of the Bahmani Sultanate. In 1490, Ahmadnagar declared independence, followed by Bijapur and Berar in the same year.
