I want to know the answer to the following question:
What port was lost by the Ottoman empire as a result of the Treaty of Belgrade?
All the background I'm provided with is that "The Austro-Russian–Turkish War, which was ended by the Treaty of Belgrade in 1739, resulted in the recovery of Serbia and Oltenia, but the Empire lost the port of Azov, north of the Crimean Peninsula, to the Russians.". Is that enough to answer the question?
Answer: yes
