I want to know the answer to the following question:
What official title did the Viceroy of Deccan hold?
All the background I'm provided with is that "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.". Is that enough to answer the question?
