Mir Osman Ali Khan, Last Nizam of Hyderabad State (born 1886)

Mir Osman Ali Khan, Asaf Jah VII was the last Nizam (ruler) of Hyderabad State, the largest state in the erstwhile Indian Empire. He ascended the throne on 29 August 1911, at the age of 25 and ruled the State of Hyderabad between until 1948, when the Indian Union 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 estimates 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 mint, printing his 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. 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, and used by the Nizam as a paperweight.

Nizam of Hyderabad was the title of the ruler of Hyderabad State. Nizam is a shortened form of Niẓām ul-Mulk, and was the title bestowed upon Asaf Jah I when he was appointed Viceroy of the Deccan by the Mughal emperor Farrukhsiyar. In addition to being the Mughal viceroy (Naib) of the Deccan, Asaf Jah I was also the premier courtier of the Mughal Empire until 1724, when he established an independent realm based in Hyderabad, but in practice, continued to recognise the nominal authority of emperor.

Hyderabad State was a princely state in the Deccan region of south-central India with its capital at the city of Hyderabad. It is now divided into the present-day state of Telangana, the Kalyana-Karnataka region of Karnataka, and the Marathwada region of Maharashtra in India.
