I want to know the answer to the following question:
In what year did the establishment of the Qutb dynasty occur?
All the background I'm provided with is that "Sultan Quli, a governor of Golkonda, revolted against the Bahmani Sultanate and established the Qutb Shahi dynasty in 1518; he rebuilt the mud-fort of Golconda and named the city "Muhammad nagar".". Is that enough to answer the question?
