Gulbarga Fort, located in the city of Gulbarga (Kalaburagi), Karnataka, is a historic fortification that reflects the architectural and strategic prowess of the Bahmani Sultanate. The fort's origins date back to the 12th century, though it was significantly expanded and fortified during the Bahmani rule in the 14th and 15th centuries. Historical Background Gulbarga Fort originally began as a smaller fortification under the Kakatiya dynasty. However, it gained prominence when Sultan Ala-ud-Din Bahman Shah adopted it as the capital of the Bahmani Sultanate in 1347. The fort served as the sultanate's political and administrative center until the capital was later moved to Bidar in 1427. Despite the shift in capital, Gulbarga remained an important military and administrative hub.
