Tucked away in the distant north of Karnataka, Bidar is a piece of Isfahan transplanted in the heart of the Deccan. Once the capital of the Bahmani Sultanate and later one of the five splinter Deccan Sultanates, Bidar was the beating heat of Islamic culture in the Deccan during the middle ages. Though now abandoned it still reflects evidence of its grand past in some truly monumental architecture. Bidar Fort is the largest fort in the Deccan and the Mahmud Gawan Madrasa is distinctly Iranian in its architecture. The Bahanamis of Deccan left an important heritage of Indo-Islamic art, language, and spread of Islamic tradition in South India. The Bahamanis paved way for the distinct style of architecture by inviting architects from Persia, Turkey, and Arabia and blended it with local styles.
