Asaf Jah VII of Hyderabad

Mir Osman Ali Khan, Asaf Jah VII (5 or 6 April 1886 – 24 February 1967) was the last Nizam (ruler) of the Princely State of Hyderabad, the largest princely state in British India. He ascended the throne on 29 August 1911, at the age of 25 and ruled the Kingdom of Hyderabad between 1911 and 1948, until India annexed it. He was styled as His Exalted Highness-(H.E.H) the Nizam of Hyderabad, and was widely considered one of the world's wealthiest people of all time. With some estimate placing his wealth at 2% of U.S. GDP, his portrait was on the cover of Time magazine in 1937. As a semi-autonomous monarch, he had his own mint, printing his own currency, the Hyderabadi rupee, and had a private treasury that was said to contain £100 million in gold and silver bullion, and a further £400 million of jewels (in 2008 terms). The major source of his wealth was the Golconda mines, the only supplier of diamonds in the world at that time. Among them was the Jacob Diamond, valued at some £50 million (in 2008 terms), and used by the Nizam as a paperweight. During his 37-year rule, electricity was introduced, and railways, roads, and airports were developed. He was known as the "Architect of modern Hyderabad" and is credited with establishing many public institutions in the city of Hyderabad, including Osmania University, Osmania General Hospital, State Bank of Hyderabad, Begumpet Airport, and the Hyderabad High Court. Two reservoirs, Osman Sagar and Himayat Sagar, were built during his reign, to prevent another great flood in the city. The Nizam also constructed the Nizam Sagar Dam and, in 1923, a reservoir constructed across the Manjira River, a tributary of the Godavari River, between Achampet and BanjePally villages of the Kamareddy district in Telangana, India. It is located at about 144 km (89 mi) north-west of Hyderabad. Nizam Sagar is the oldest dam in the state of Telangana. The Nizam had refused to accede Hyderabad to India after the country's independence on 15 August 1947. He wanted his domains to remain an independent state or join Pakistan. Later, he wanted his state to join India; however, his power had weakened because of the Telangana Rebellion and the rise of a radical militia known as the Razakars, whom he could not put down. In 1948, the Indian Army invaded and annexed Hyderabad State and defeated the Razakars.
