The Bahmani Sultanate (also called the Bahmanid Empire or Bahmani Kingdom) was a Muslim state of the Deccan in South India and one of the great medieval Indian kingdoms. Bahmanid Sultanate was the first independent Islamic Kingdom in South India.
The empire was established by Turkic general Ala-ud-Din Bahman Shah after revolting against the Delhi Sultanate of Muhammad bin Tughlaq. Nazir Uddin Ismail Shah who had revolted against the Delhi Sultanate stepped down on that day in favour of Bahman Shah. His revolt was successful, and he established an independent state on the Deccan within the Delhi Sultanate’s southern provinces. The Bahmani capital was Ahsanabad (Gulbarga) between 1347 and 1425 when it was moved to Muhammadabad (Bidar). The Bahmani contested the control of the Deccan with the Vijayanagara Empire to the south. The sultanate reached the peak of its power during the vizierate (1466–1481) of Mahmud Gawan.
The south Indian Emperor Krishnadevaraya of the Vijayanagara Empire defeated the last remnant of Bahmani Sultanate power after which the Bahmani Sultanate collapsed. After 1518 the sultanate broke up into five states: Nizamshahi of Ahmednagar, Qutb Shahi of Golconda (Hyderabad), Baridshahi of Bidar, Imadshahi of Berar, Adilshahi of Bijapur. They are collectively known as the “Deccan Sultanates”.
The Bahmanis encouraged a distinct style by inviting architects from various parts of the Muslim world and blending them with local styles. The resulting culture was a blend of both northern and southern styles and had its own distinct elements. Gumbaz (the largest dome in the world) and Charminar located at Hyderabad are world-famous examples of Bahamani architecture.
