One example of the wealth of the Nizams are the Jewels of the Nizams, an international tourist attraction once displayed in Salar Jung Museum, but now locked in an Reserve Bank of India vault in Delhi. In 1948 Hyderabad state had an estimated population of 17 million (1.7 crore), and it generated an estimated annual revenue of £90,029,000.
