In 1713 Farrukhsiyar, the Mughal emperor, appointed Asif Jah I to be Viceroy of the Deccan, with the title Nizam-ul-Mulk (Administrator of the Realm). In 1724, Asif Jah I defeated Mubariz Khan to establish autonomy over the Deccan Suba, named the region Hyderabad Deccan, and started what came to be known as the Asif Jahi dynasty. Subsequent rulers retained the title Nizam ul-Mulk and were referred to as Asif Jahi Nizams, or Nizams of Hyderabad. The death of Asif Jah I in 1748 resulted in a period of political unrest as his sons, backed by opportunistic neighbouring states and colonial foreign forces, contended for the throne. The accession of Asif Jah II, who reigned from 1762 to 1803, ended the instability. In 1768 he signed the treaty of Masulipatnam, surrendering the coastal region to the East India Company in return for a fixed annual rent.
