Mahboob Ali Khan, 6th Nizam of Hyderabad (died 1911)

Asaf Jah VI, also known as Sir Mir Mahboob Ali Khan Siddiqi, was the sixth Nizam of Hyderabad. He ruled Hyderabad State, one of the princely states of India, between 1869 and 1911.

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.
