I want to know the answer to the following question:
What ruler recognized the Ottomans in 1547?
All the background I'm provided with is that "The French conquests of Nice (1543) and Corsica (1553) occurred as a joint venture between the forces of the French king Francis I and Suleiman, and were commanded by the Ottoman admirals Barbarossa Hayreddin Pasha and Turgut Reis.". Is that enough to answer the question?
Answer: no
