I want to know the answer to the following question:
Who was treated as second class citizens under the Ottomans?
All the background I'm provided with is that "The goal was to promote year-round trade and a year-round navy.:11 Pursuit of this goal brought the emerging Russian state into conflict with the Ukrainian Cossacks and then with the Tatars of the Crimean Khanate and Circassians.". Is that enough to answer the question?
Answer: no
