Named after Hyder Mahal, wife of Muhammad Quli, a 16th-century ruler of the Qutb Shahi dynasty, Hyderabad was one of the largest and wealthiest of India's former princely states. The city built its fortune on the trade of pearls, gold, steel, fabric, and, above all, diamonds, which some believe remains hidden beneath the foundations of Giaconda Fort, precursor to the city some 10km (6 1/4 miles) away. Once the most famous diamond mining area in the world, Golconda was where the 108-carat Koh-i-Noor diamond (not to mention the Orloff, Regent, and Hope diamonds) was excavated. It was in fact Golconda's legendary wealth that attracted the attention of the voracious Mughal emperor Aurangzeb, and with the aid of an inside agent he captured the fortress in 1687. Aurangzeb's invasion marked the temporary decline of the city, but when the Mughal empire began to fade, the enterprising local viceroy, Asaf Jah I, promptly proclaimed himself Nizam, and established independent rule over the Deccan state. Under the notoriously opulent Nizams of the Asaf Jahi dynasty, their power cemented by an alliance forged in 1798 with the British East India Company, Hyderabad again became a major influence, and even contributed to the British military campaigns against the recalcitrant Tipu Sultan of Mysore.
