Explanation:

The Deccan sultanates refer to five Muslim-ruled late medieval kingdoms–-Bijapur, Golkonda, Ahmadnagar, Bidar, and Berar of south-central India. The Deccan sultanates located on the Deccan Plateau, between the Krishna River and the Vindhya Range. They had become independent states during the breakup of the Bahmani Sultanate: Bijapur, Ahmadnagar, and Berar in 1490, Bidar in 1492, and Golkonda in 1512. In 1510, Bijapur repulsed an invasion by the Portuguese against the city of Goa, but lost it later that year.

The Barid Shahi rulers focused their architectural activities on garden tombs. The tomb of Ali Barid Shah (1577) represents the most notable monument in Bidar.
